II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to introduce a new index options product, 
Nasdaq Bitcoin Index Options. This product would enable retail and 
institutional investors to obtain a precise price for bitcoin. Nasdaq 
Bitcoin Index Options is represented by the CME CF Bitcoin Real Time 
Index, a precise spot market source for bitcoin pricing and a leading 
price benchmark for real time valuations. The CME CF Bitcoin Real Time 
Index is a Registered Benchmark under EU BMR.\5\
---------------------------------------------------------------------------

    \5\ Today, the CME CF Bitcoin Reference Rate--New York Variant 
for the Bitcoin--U.S. Dollar trading pair (the ``CF Benchmarks 
Index'') constitutes the index for the following exchange-listed ETF 
products comprising $58 billion of assets as of July 18, 2024: 
iShares Bitcoin Trust (IBIT), Grayscale Bitcoin Trust (GBTC), 
Fidelity Wise Origin Bitcoin Fund (FBTC), ARK 21Shares Bitcoin ETF 
(ARKB), Bitwise Bitcoin ETF Trust (BUTB), VanEck Bitcoin Trust 
(HODL), Coinshares Valkyrie Bitcoin Fund (BRRR), Invesco Galaxy 
Bitcoin ETF (BTCO), Franklin Bitcoin ETF (EZBC). (See <a href="https://etfdb.com/index/cme-cf-benchmarks-bitcoin-reference-rate-new-york-variant">https://etfdb.com/index/cme-cf-benchmarks-bitcoin-reference-rate-new-york-variant</a>).
---------------------------------------------------------------------------

Background
    The CME CF Bitcoin Real Time Index (``BRTI'') is calculated every 
second of every day, using the Relevant Order Books \6\ of all 
Constituent Exchanges,\7\ thereby aggregating the notional value of 
bitcoin trading activity across major bitcoin spot platforms. The CF 
Benchmarks Index is designed based on the IOSCO Principles for 
Financial Benchmarks.\8\ The administrator of the CF Benchmarks Index 
is CF Benchmarks Ltd. The CF Benchmarks Index serves as a once-a-day 
benchmark rate of the U.S. dollar price of bitcoin (USD/BTC), 
calculated as of 4:00 p.m. ET. The CF Benchmarks Index aggregates the 
trade flow of several bitcoin platforms, during an observation window 
between 3:00 p.m. and 4:00 p.m. ET into the U.S. dollar price of one 
bitcoin at 4:00 p.m. ET. Specifically, the CF Benchmarks Index is 
calculated based on the Relevant Transactions of all of its constituent 
bitcoin platforms, which are currently Bitstamp, Coinbase, itBit, 
Kraken, Gemini, and LMAX (the ``Constituent Platforms''), and which may 
change from time to time.\9\
---------------------------------------------------------------------------

    \6\ Relevant Order Books comprise the universe of the currently 
unmatched limit orders to buy or sell a unit of the cryptocurrency 
base asset versus the quote asset on a Constituent Exchange in the 
Relevant Pair, aggregated by price, that is reported through its API 
to the Calculation Agent. To assure that the CME CF Cryptocurrency 
Pricing Products reflect global cryptocurrency trading activity in a 
representative and unbiased manner, a geographically diverse set of 
spot trading venues is included within the current framework. At 
their launch the Indices for any given Relevant Pair shall require 
input data from no less than two (2) Constituent Exchanges.
    \7\ Constituent Exchanges are cryptocurrency trading venues 
approved by the CME CF Cryptocurrency Pricing Products Oversight 
Committee to serve as pricing source for the calculation of a CME CF 
Cryptocurrency Reference Rate or CME CF Cryptocurrency Real Time 
Index, collectively known as the CME CF Cryptocurrency Pricing 
Products. See proposed Options 4D, Section 2(a)(2).
    \8\ See <a href="https://www.iosco.org/library/pubdocs/pdf/IOSCOPD589.pdf">https://www.iosco.org/library/pubdocs/pdf/IOSCOPD589.pdf</a>.
    \9\ All aspects of the Index Methodology are publicly available 
at the website of Index Provider, CF Benchmarks. See <a href="https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf</a>.
---------------------------------------------------------------------------

    A trading venue is eligible as a Constituent Exchange in any of the 
CME CF Cryptocurrency Pricing Products if it offers a market that 
facilitates the spot trading of the relevant cryptocurrency base asset 
against the corresponding quote asset, including markets where the 
quote asset is made fungible with Accepted Assets (the ``Relevant 
Pair'') and makes trade data and order data available through an 
Automatic Programming Interface (``API'') with sufficient reliability, 
detail and timeliness. Furthermore, it must meet certain criteria.\10\ 
Should the average

[[Page 10546]]

daily contribution of a Constituent Exchange fall below 3% for any 
Reference Rate, then the continued inclusion of the venue as a 
Constituent Exchange to the Relevant Pair shall be assessed by the CME 
CF Oversight Committee.
---------------------------------------------------------------------------

    \10\ The venue's Relevant Pair spot trading volume for an index 
must meet the minimum thresholds for it to be admitted as a 
Constituent Exchange. The average daily volume the venue would have 
contributed during the observation window for the Reference Rate of 
the Relevant Pair exceeds 3% for two consecutive calendar quarters. 
The venue has policies to ensure fair and transparent market 
conditions at all times and has processes in place to identify and 
impede illegal, unfair or manipulative trading practices. The venue 
does not impose undue barriers to entry or restrictions on market 
participants, and utilizing the venue does not expose market 
participants to undue credit risk, operational risk, legal risk or 
other risks. The venue complies with applicable law and regulation, 
including, but not limited to capital markets regulations, money 
transmission regulations, client money custody regulations, know-
your-client (``KYC'') regulations and anti-money laundering 
regulations. Finally, the venue cooperates with inquiries and 
investigations of regulators and the Administrator upon request and 
must execute data sharing agreements with CME Group Once admitted a 
constituent exchange must demonstrate that it continues to meet the 
aforementioned criteria.
---------------------------------------------------------------------------

    When calculated, the Relevant Order Book of each Constituent 
Exchange is added to a joint list of order books,\11\ which are 
aggregated into one consolidated order book. If the size at the bid or 
ask order price level exceeds the order size cap, it enters the 
consolidated order book with a size equal to the order size cap. The 
cumulative bid price-volume curve, ask price-volume curve, mid price-
volume curve \12\ and mid spread-volume curve are calculated from the 
consolidated order book at a granularity equal to the spacing 
parameter.
---------------------------------------------------------------------------

    \11\ An order book is a list of buy and sell orders with 
associated limit prices and sizes that have not yet been matched due 
to lack of supply or demand to trade at that price. CME CF 
Cryptocurrency Real Time Indices are calculated from order book 
data, as opposed to, for instance, trade data.
    \12\ The mid price-volume curve represents the average of the 
marginal price at which a certain amount of cryptocurrency can be 
sold and bought. By averaging across the mid price-volume curve, CME 
CF Cryptocurrency Real Time Indices represent a blend of such 
(hypothetical) transactions at various transaction sizes. See 
<a href="https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf</a>.
---------------------------------------------------------------------------

    Using the above notation, the ask price-volume curve is defined as 
askPV, the bid price-volume curve as bidPV, the mid-price volume curve 
as midPV, and the mid spread-volume curve as midSV, in each case as of 
the effective time T, as:
[GRAPHIC] [TIFF OMITTED] TN24FE25.000

    The utilized depth is calculated as the maximum cumulative volume 
for which the mid spread-volume curve does not exceed a certain 
percentage deviation from the mid price.\13\ If this volume is less 
than the spacing parameter, the utilized depth is set to the spacing 
parameter. The utilized depth, v, is calculated as:
---------------------------------------------------------------------------

    \13\ CME CF Cryptocurrency Real Time Indices are calculated from 
the section of the mid price-volume curve for which ask limit order 
price levels at a certain depth diverge by no more than a certain 
percentage from the mid-price at that depth. It therefore reflects a 
significant portion of the top of the consolidated order book (as 
opposed to, for instance, the best bid and ask prices only) but 
discards limit order price levels that are less likely to be 
matched. This makes it a meaningful representation of true liquidity 
and robust to local changes in order books. See <a href="https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf</a>.
[GRAPHIC] [TIFF OMITTED] TN24FE25.001

    The mid price-volume curve is weighted by the normalized 
probability density of the exponential distribution up to the utilized 
depth. The CME CF Cryptocurrency Real Time Index is then given by the 
sum of the weighted mid price-volume curve obtained in the previous 
step.\14\ The CME CF Cryptocurrency Real Time Index as of the effective 
time T, CCRTI, is then given by:
---------------------------------------------------------------------------

    \14\ See the qualitative description of the calculation 
methodology at <a href="https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf</a>.
[GRAPHIC] [TIFF OMITTED] TN24FE25.002

    The order size cap is calculated from the uncapped consolidated 
order book. Using the above notation, the dynamic order size cap is 
derived as follows:

[[Page 10547]]

[GRAPHIC] [TIFF OMITTED] TN24FE25.003

    The order size cap as of the effective time T, C, is then given by:
    [GRAPHIC] [TIFF OMITTED] TN24FE25.004
    
    If the Retrieval Time of the Relevant Order Book of a Constituent 
Exchange is at least 30 seconds older than the Calculation Time, the 
Constituent Exchange is disregarded in the calculation of the CME CF 
Cryptocurrency Real Time Index for that Calculation Time. If the 
Retrieval Times of the Relevant Order Books of all Constituent 
Exchanges are each at least 30 seconds older than the Calculation Time, 
a CME CF Cryptocurrency Real Time Index calculation failure occurs for 
that Calculation Time. All Relevant Order Books are subject to an 
automated screening for erroneous data.\15\
---------------------------------------------------------------------------

    \15\ If the format of a Relevant Order Book: deviates from the 
expected format such that it cannot be parsed; contains no bid 
orders or no ask orders; crosses; or contains any entries with a 
non-numeric or non-positive limit price or size, it is flagged as 
erroneous. Relevant Order Books flagged as erroneous for a given 
Calculation Time are disregarded in the calculation of the CME CF 
Cryptocurrency Real Time Index for that Calculation Time. See 
<a href="https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Real%20Time%20Indices%20Methodology.pdf</a>.
---------------------------------------------------------------------------

Overview of the Bitcoin Industry
    Bitcoin is a digital asset that is created and transmitted through 
the operations of the peer-to-peer bitcoin network, a decentralized 
network of computers that operates on cryptographic protocols (the 
``Bitcoin network''). No single entity owns or operates the Bitcoin 
network, the infrastructure of which is collectively maintained by its 
user base. The Bitcoin network allows people to exchange tokens of 
value, called bitcoin, which are recorded on a public transaction 
ledger known as the Bitcoin blockchain (the ``Bitcoin blockchain''). 
Bitcoin can be used to pay for goods and services, or it can be 
converted to fiat currencies, such as the U.S. dollar, at rates 
determined on bitcoin platforms that enable trading in bitcoin or in 
individual end-user-to-end-user transactions under a barter system.
    The Bitcoin network is commonly understood to be decentralized and 
does not require governmental authorities or financial institution 
intermediaries to create, transmit or determine the value of bitcoin. 
Rather, bitcoin is created and allocated by the Bitcoin network 
protocol through a ``mining'' process. The value of bitcoin is 
determined by the supply of and demand for bitcoin-on-bitcoin platforms 
or in private end-user-to-end-user transactions.
    New bitcoins are created and rewarded to the miners of a block in 
the Bitcoin blockchain for verifying transactions. The Bitcoin 
blockchain is a shared database that includes all blocks that have been 
solved by miners and it is updated to include new blocks as they are 
solved. Each bitcoin transaction is broadcast to the Bitcoin network 
and, when included in a block, recorded in the Bitcoin blockchain. As 
each new block records outstanding bitcoin transactions, and 
outstanding transactions are settled and validated through such 
recording, the Bitcoin blockchain represents a complete, transparent 
and unbroken history of all transactions of the Bitcoin network.
History of Bitcoin
    The Bitcoin network was initially contemplated in a whitepaper that 
also described bitcoin and the operating software to govern the Bitcoin 
network. The whitepaper was purportedly authored by Satoshi Nakamoto. 
However, no individual with that name has been reliably identified as 
bitcoin's creator, and the general consensus is that the name is likely 
a pseudonym for the actual inventor or inventors. The

[[Page 10548]]

first bitcoins were created in 2009 after Nakamoto released the Bitcoin 
network source code (the software and protocol that created and 
launched the Bitcoin network). The Bitcoin network has been under 
active development since that time by a loose group of software 
developers who have come to be known as core developers.
Overview of Bitcoin Network Operations
    In order to own, transfer or use bitcoin directly on the Bitcoin 
network (as opposed to through an intermediary, such as an exchange), a 
person generally must have internet access to connect to the Bitcoin 
network. Bitcoin transactions may be made directly between end-users 
without the need for a third-party intermediary. To prevent the 
possibility of double-spending bitcoin, a user must notify the Bitcoin 
network of the transaction by broadcasting the transaction data to its 
network peers. The Bitcoin network provides confirmation against 
double-spending by memorializing every transaction in the Bitcoin 
blockchain, which is publicly accessible and transparent. This 
memorialization and verification against double-spending is 
accomplished through the Bitcoin network mining process, which adds 
``blocks'' of data, including recent transaction information, to the 
Bitcoin blockchain.
Overview of Bitcoin Transfers
    Prior to engaging in bitcoin transactions directly on the Bitcoin 
network, a user generally must first install on its computer or mobile 
device a Bitcoin network software program that will allow the user to 
generate a private and public key pair associated with a bitcoin 
address commonly referred to as a ``wallet.'' The Bitcoin network 
software program and the bitcoin address also enable the user to 
connect to the Bitcoin network and transfer bitcoin to, and receive 
bitcoin from, other users.
    Each Bitcoin network address, or wallet, is associated with a 
unique ``public key'' and ``private key'' pair. To receive bitcoin, the 
bitcoin recipient must provide its public key to the party initiating 
the transfer. This activity is analogous to a recipient for a 
transaction in U.S. dollars providing a routing address in wire 
instructions to the payor so that cash may be wired to the recipient's 
account. The payor approves the transfer to the address provided by the 
recipient by ``signing'' a transaction that consists of the recipient's 
public key with the private key of the address from where the payor is 
transferring the bitcoin. The recipient, however, does not make public 
or provide to the sender its related private key.
    Neither the recipient nor the sender reveals their private keys in 
a transaction because the private key authorizes transfer of the funds 
in that address to other users. Therefore, if a user loses his or her 
private key, the user may permanently lose access to the bitcoin 
contained in the associated address. Likewise, bitcoin is irretrievably 
lost if the private key associated with them is deleted and no backup 
has been made. When sending bitcoin, a user's Bitcoin network software 
program must validate the transaction with the associated private key. 
The resulting digitally validated transaction is sent by the user's 
Bitcoin network software program to the Bitcoin network to allow 
transaction confirmation.
    Some bitcoin transactions are conducted ``off-blockchain'' and are 
therefore not recorded in the Bitcoin blockchain. Some ``off-blockchain 
transactions'' involve the transfer of control over, or ownership of, a 
specific digital wallet holding bitcoin or the reallocation of 
ownership of certain bitcoin in a digital wallet containing assets 
owned by multiple persons, such as a digital wallet maintained by a 
digital assets platform. In contrast to on-blockchain transactions, 
which are publicly recorded on the Bitcoin blockchain, information and 
data regarding off-blockchain transactions are generally not publicly 
available. Therefore, off-blockchain transactions are not truly bitcoin 
transactions in that they do not involve the transfer of transaction 
data on the Bitcoin network and do not reflect a movement of bitcoin 
between addresses recorded in the Bitcoin blockchain. For these 
reasons, off-blockchain transactions are subject to risks as any such 
transfer of bitcoin ownership is not protected by the protocol behind 
the Bitcoin network or recorded in, and validated through, the 
blockchain mechanism.
Summary of a Bitcoin Transaction
    In a bitcoin transaction directly on the Bitcoin network between 
two parties (as opposed to through an intermediary, such as a 
custodian), the following circumstances must initially be in place: (i) 
the party seeking to send bitcoin must have a Bitcoin network public 
key, and the Bitcoin network must recognize that public key as having 
sufficient bitcoin for the transaction; (ii) the receiving party must 
have a Bitcoin network public key; and (iii) the spending party must 
have internet access with which to send its spending transaction.
    The receiving party must provide the spending party with its public 
key and allow the Bitcoin blockchain to record the sending of bitcoin 
to that public key. After the provision of a recipient's Bitcoin 
network public key, the spending party must enter the address into its 
Bitcoin network software program along with the number of bitcoin to be 
sent. The number of bitcoin to be sent will typically be agreed upon 
between the two parties based on a set number of bitcoin or an agreed 
upon conversion of the value of fiat currency to bitcoin. Since every 
computation on the Bitcoin network requires the payment of bitcoin, 
including verification and memorialization of bitcoin transfers, there 
is a transaction fee involved with the transfer, which is based on 
computation complexity and not on the value of the transfer and is paid 
by the payor with a fractional number of bitcoin.
    After the entry of the Bitcoin network address, the number of 
bitcoin to be sent and the transaction fees, if any, to be paid, will 
be transmitted by the spending party. The transmission of the spending 
transaction results in the creation of a data packet by the spending 
party's Bitcoin network software program, which is transmitted onto the 
decentralized Bitcoin network, resulting in the distribution of the 
information among the software programs of users across the Bitcoin 
network for eventual inclusion in the Bitcoin blockchain.
    As discussed in greater detail below, Bitcoin network miners record 
transactions when they solve for and add blocks of information to the 
Bitcoin blockchain. When a miner solves for a block, it creates that 
block, which includes data relating to (i) the solution to the block, 
(ii) a reference to the prior block in the Bitcoin blockchain to which 
the new block is being added and (iii) transactions that have occurred 
but have not yet been added to the Bitcoin blockchain. The miner 
becomes aware of outstanding, unrecorded transactions through the data 
packet transmission and distribution discussed above.
    Upon the addition of a block included in the Bitcoin blockchain, 
the Bitcoin network software program of both the spending party and the 
receiving party will show confirmation of the transaction on the 
Bitcoin blockchain and reflect an adjustment to the bitcoin balance in 
each party's Bitcoin network public key, completing the bitcoin 
transaction. Once a transaction is

[[Page 10549]]

confirmed on the Bitcoin blockchain, it is irreversible.
Creation of a New Bitcoin
    New bitcoins are created through the mining process. The process by 
which bitcoin is ``mined'' results in new blocks being added to the 
Bitcoin blockchain and new bitcoin tokens being issued to the miners. 
Computers on the Bitcoin network engage in a set of prescribed complex 
mathematical calculations in order to add a block to the Bitcoin 
blockchain and thereby confirm bitcoin transactions included in that 
block's data. The Bitcoin network is designed in such a way that the 
reward for adding new blocks to the Bitcoin blockchain decreases over 
time. In the future, once new bitcoin tokens are no longer awarded for 
adding a new block, miners will only have transaction fees to 
incentivize them, and as a result, it is expected that miners will need 
to be better compensated with higher transaction fees to ensure that 
there is adequate incentive for them to continue mining.
Limits on Bitcoin Supply
    Under the source code that governs the Bitcoin network, the supply 
of new bitcoin is mathematically controlled so that the number of 
bitcoin grows at a limited rate pursuant to a pre-set schedule. The 
number of bitcoin awarded for solving a new block is automatically 
halved after every 210,000 blocks are added to the Bitcoin blockchain, 
approximately every 4 years. The fixed reward for solving a new Bitcoin 
block is currently 3.125 BTC per block. This amount is the result of 
the most recent Bitcoin halving event, which occurred in April 2024. 
The next Bitcoin halving is anticipated in 2028 when Bitcoin will halve 
to 1.5625. This deliberately controlled rate of bitcoin creation means 
that the number of bitcoin in existence will increase at a controlled 
rate until the number of bitcoin in existence reaches the pre-
determined 21 million bitcoin. However, the 21 million supply cap could 
be changed in a hard fork. A hard fork could change the source code to 
the Bitcoin network, including the 21 million bitcoin supply cap.
Bitcoin as an Underlying for an Index
    The proposed product is a cash-settled index option that permits 
holders to receive U.S. dollars representing the difference between the 
current bitcoin spot market and the exercise price of the option and 
would not involve holding physical bitcoin similar to the approved 
Bitcoin-Based Commodity-Based Trust Shares and Trust (collectively 
``Spot Bitcoin ETPs'') \16\ which entailed the custody of bitcoin 
assets.

    In 2006, Phlx received approval to list and trade foreign currency 
index options.\17\ These foreign currency options are cash-settled, 
European-styled options issued by The Options Clearing Corporation 
(``OCC'') that permit holders to receive U.S. dollars representing the 
difference between the current foreign exchange spot price and the 
exercise price of the option.\18\ Further, similar to this proposal, 
Phlx noted in SR-Phlx-2026-34, its proposal seeking approval for 
foreign currency options (or ``U.S. dollar-settled FCOs''), that ``U.S. 
dollar-settled FCOs would trade in the same general manner as equity 
index options, which are also U.S. dollar-settled products.'' \19\ The 
Commission noted in the SR-Phlx-2006-34 approval order that it believed 
that, ``. . . . sufficient venues exist for obtaining reliable 
information on the Currencies so that investors in U.S. dollar-settled 
FCOs can monitor the underlying spot market in the Currencies. The 
Commission also believes that the Phlx's procedures and the competitive 
nature of the spot market for the [c]urrencies should help to ensure 
that the settlement values for U.S. dollar-settled FCO contracts will 
accurately reflect the spot price for foreign currencies . . .''.\20\

    Foreign currency options established precedent to list and trade 
index options overlying an underlying that is not a security, such as 
proposed herein. Like foreign currency markets, the bitcoin market is 
liquid and is characterized by a significant degree of volume and 
turnover. As a result, the Exchange believes that sufficient venues 
exist to provide investors with ready access to reliable information on 
the spot market price of bitcoin for purposes of this product.\21\ 
While bitcoin is a novel asset, the requirements of a benchmark price 
for bitcoin are no different from those required of a benchmark price 
for any asset.
---------------------------------------------------------------------------

    \21\ Today, there are regulated bitcoin futures and options on 
futures derivatives contracts from CME Group and Eurex AG, approved 
regulated spot FTSE Bitcoin Index futures as well as a variety of 
other regulated exchange traded products and funds in Canada, 
Brazil, Hong Kong and Europe.
---------------------------------------------------------------------------

Final Settlement
    The final settlement value for Nasdaq Bitcoin Index Options would 
be the CME CF Bitcoin Reference Rate--New York Variant (BRRNY) on the 
expiration date (usually a Friday). BRRNY will be divided by a factor 
of one hundred (100) to create a new settlement value to arrive at the 
settlement value for Nasdaq Bitcoin Index Options, which will be 
published as BRRNY--NOS (Nasdaq Options Settlement). BRRNY is a once-a-
day benchmark index price for bitcoin that aggregates trade data from 
multiple bitcoin-USD markets operated by major cryptocurrency exchanges 
that conform to the CME CF Constituent Exchange Criteria. It is 
synchronized to the traditional U.S. financial market close of 1600 New 
York Time and is calculated every single day of the year. The index is 
a Registered Benchmark under UK BMR and as such is a Third Country 
benchmark under the EU BMR Regime.
    The BRRNY index is methodologically identical to the regulated CME 
CF Bitcoin Reference Rate (BRR), the most widely used benchmark price 
for Bitcoin, that settles the Bitcoin-USD derivatives complex listed by 
CME Group, and which serves as the NAV for exchange listed investment 
products from WisdomTree Europe, Evolve ETFs (CAN) and QR Asset 
Management (BRZ). The only difference between the CME CF BRRNY and the 
CME CF BRR, is that BRRNY references the price of bitcoin at the 
closing time of U.S. markets, 16:00 New York Time, rather than the 
price at 16:00 London Time, referenced by the BRR.
    The purpose of BRRNY is to provide a replicable, manipulation-
resistant and representative Bitcoin benchmark that synchronizes with 
the traditional U.S. market close. The CME CF Bitcoin Reference Rate--
New York Variant is a regulated Benchmark under the UK Benchmarks 
Regulation (BMR) regime. The BRRNY calculation methodology aggregates 
transactions of Bitcoins in U.S. dollars that are only conducted on the 
most liquid markets for which data is publicly available and operated 
by

exchanges that meet the CME CF Constituent Exchange Criteria.\22\
---------------------------------------------------------------------------

    \22\ See infra note 25.
---------------------------------------------------------------------------

    BRRNY is a valid and robust benchmark that is calculated from input 
data of sufficient volume so that it is representative of the market it 
seeks to measure. Additionally, BRRNY has volume sufficiency which 
permits it be replicated by institutional market participants and 
product providers that need to warehouse price risk. The below table 
summarizes the total number of transactions and average number of 
transactions per day observed each month for BRRNY.\23\ Between 
February 28, 2022, and January 31, 2024 (weekdays only), on average 
2,116.73 Bitcoins, or $59M were traded during each daily observation 
window between 15:00 and 16:00 New York Time.\24\
---------------------------------------------------------------------------

    \23\ The data represents both trade count and bitcoin volume 
during the observation window.
    \24\ BRRNY was launched on February 28, 2022. LMAX Digital was 
added as a Constituent Exchange from May 2022.

    This trading activity exhibits volatility that is not substantially 
different from that shown in traditional asset markets. The volume 
observed and the reliability of that volume are clearly evident to be 
sufficient for the calculation of a robust and reliable benchmark.
    Phlx believes that Nasdaq Bitcoin Index Options will be utilized 
for a wide range of activities such as asset valuation, settlement of 
financial risk, risk management, NAV calculation, unit creation and 
unit redemption. To that end, the index design is fair and transparent. 
CF Benchmarks exclusively sources input data from Constituent Exchanges 
that meet published criteria as set out in its Constituent Exchanges 
Criteria and conducts a thorough review of any exchange under 
consideration for inclusion as a Constituent Exchange.\25\ BRRNY 
methodology takes an observation period and divides it into equal 
partitions of time. The volume-weighted median of all transactions 
within each partition is then calculated. The benchmark index value is 
determined from the arithmetic mean of the volume-weighted medians, 
equally weighted. As a result, individual trades of large size have 
limited effect on the index level as they only influence the level of 
the volume-weighted median for that specific partition. Further, a 
cluster of trades in a short period of time will also only influence 
the volume-weighted median of the partition or partitions they were 
conducted in, thereby limiting impact. Use of volume-weighted medians 
as opposed to volume-weighted means ensures that transactions conducted 
at outlying prices do not have an undue effect on the value of a 
specific partition. By not volume weighting partitions, trades of large 
size or clusters of trades over a short period of time will not have an 
undue influence on the index level. CF Benchmarks applies equal weight 
to transactions observed from CME CF Constituent Exchanges. With no 
pre-set weights, the BRRNY index is not readily subject to 
manipulation. Using the arithmetic mean of partitions of equal weight 
further denudes the effect of trades of large size at prices that 
deviate from the prevailing price having undue influence on the 
benchmark level.\26\
---------------------------------------------------------------------------

    \25\ The criteria are available at: <a href="https://docs.cfbenchmarks.com/CME%20CF%20Constituent%20Exchanges%20Criteria.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Constituent%20Exchanges%20Criteria.pdf</a>. The arrangements 
of all Constituent Exchanges are reviewed annually to ensure that 
they continue to meet all criteria specified within ``Constituent 
Exchange Criteria.'' This due diligence is documented, and the 
information is distributed to CF Benchmarks' oversight organs to 
consider. The deliberations of oversight organs are conducted during 
regular meetings, minutes of such meetings are publicly available, 
being published by the administrator on its website.
    \26\ See also <a href="https://www.cfbenchmarks.com/blog/suitability-analysis-of-the-cme-cf-bitcoin-reference-ratenew-york-variant-as-a-basis-for-regulated-financial-products-february-2024-update">https://www.cfbenchmarks.com/blog/suitability-analysis-of-the-cme-cf-bitcoin-reference-ratenew-york-variant-as-a-basis-for-regulated-financial-products-february-2024-update</a>.
---------------------------------------------------------------------------

    BRRNY's methodology incorporates a procedure for potentially 
erroneous data. Although volume-weighted medians of transaction prices 
from individual data sources are not part of the benchmark 
determination process, they are calculated as a means of quality 
control and manipulation resistance. In the event of an instance of 
index calculation in which a Constituent Exchange's volume-weighted 
median transaction price exhibits an absolute percentage deviation from 
the volume-weighted median price of other Constituent Exchange 
transactions greater than the Potentially Erroneous Data Parameter 
(10%), then transactions from that Constituent Exchange are deemed 
potentially erroneous and excluded from the index calculation. All 
instances of data excluded from a calculation trigger a Benchmark 
Surveillance Alert that is investigated. By way of example, between 
February 28, 2022, and January 31, 2024, the Potentially Erroneous Data 
Parameter of the methodology for the CME CF Bitcoin Reference Rate--New 
York Variant has never been triggered. Analysis of the max volume-
weighted median per exchange during the observation period produced the 
results in the table. The results illustrate that during the 
observation period, no Constituent Exchange's input data needed to be 
excluded due to exhibiting potential manipulation and indeed no 
individual cryptocurrency exchange exhibits a deviation percentage 
above 2.41% during this period.

[[Page 10551]]

[GRAPHIC] [TIFF OMITTED] TN24FE25.006

    CF Benchmarks has implemented a benchmark surveillance program for 
the investigation of alerts. Instances of suspected benchmark 
manipulation are escalated through appropriate regulatory channels in 
accordance with CF Benchmarks' obligations under the UK Benchmarks 
Regulation (UK BMR). As a regulated Benchmark Administrator, CF 
Benchmarks is subject to supervision by the UK FCA.\27\
---------------------------------------------------------------------------

    \27\ Furthermore, CF Benchmarks' Control Procedures with respect 
to compliance with the UK BMR have been audited by `Big Four' 
accountancy firm Deloitte. The Independent Assurance Report on 
Control Procedures Noted by CF Benchmarks Regarding Compliance with 
the UK Benchmarks Regulation as of September 12, 2022 is available 
at: <a href="https://docs.cfbenchmarks.com/Deloitte_CF%20Benchmarks%20SOC1%20Audit%20Report.pdf">https://docs.cfbenchmarks.com/Deloitte_CF%20Benchmarks%20SOC1%20Audit%20Report.pdf</a>.
---------------------------------------------------------------------------

    In terms of correlation, an analysis was undertaken of the pair-
wise correlation of prices from Constituent Exchanges on a per-minute 
basis (the price difference between transactions for each minute at 
each exchange) during the observation period. The results are shown in 
the below table.
[GRAPHIC] [TIFF OMITTED] TN24FE25.007


[[Page 10552]]


    With respect to replicability, a simple replication simulation was 
thereby conducted of BRRNY to demonstrate the extent of slippage that 
implementation of the BRR would probably encounter. The methodology was 
as follows for weekdays only.
    [ssquf] Trades are executed on n (6) Constituent Exchanges, during 
a 3,600-second window.
    [ssquf] One trade is executed every second and the price achieved 
is assumed to be the last execution price observed in that second. Its 
associated volume is assumed to be the volume executed during that 
second.
    [ssquf] If no trade is completed in any single-second period, then 
the price achieved is assumed to be the price achieved in the previous 
second, but the associated volume from the previous second is not added 
to the volume executed in the latest second.
    The results of this simulation are displayed below.
    [GRAPHIC] [TIFF OMITTED] TN24FE25.008
    
    Summary data for the above simulation is provided below.
    [GRAPHIC] [TIFF OMITTED] TN24FE25.009
    
    As evidenced above, the BRRNY can be replicated with a high degree 
of confidence and usually with slippage of no more than 1 basis point 
(0.01%). On only 6.76% of days would slippage have been greater than 5 
basis points (0.05%). Indeed, even on the most volatile day, slippage 
was approximately one half of one percent, 51.6 basis points (0.516%). 
Furthermore, in the 24-month period under observation slippage would 
have been in double-digit basis points only 10 times.
    As evidenced by the foregoing data, Nasdaq Bitcoin Index Options 
are representative of the underlying market, resistant to manipulation, 
and replicable by market participants.
Amendments to Exchange Rules
    The proposal is designed to ensure that Nasdaq Bitcoin Index 
Options are listed and traded under the same terms that apply to other 
index options that are currently traded on the Exchange. The Exchange 
proposes to create a new Options 4D, titled ``Nasdaq Bitcoin Index 
Options,'' with rules that would apply specifically to the listing and 
trading of Nasdaq Bitcoin Index Options.
Applicability
    The proposed Options 4D Rules would be applicable to Nasdaq Bitcoin 
Index Options. All Options Rules shall apply to Nasdaq Bitcoin Index 
Options, in addition to the Options 4D Rules, however where the Options 
4D Rules disagree with another Options Rule not within Options 4D a 
conflict shall be resolved in favor of the Options 4D Rule as it 
applies to Nasdaq Bitcoin Index Options.\28\
---------------------------------------------------------------------------

    \28\ See proposed Options 4D, Section 1.
---------------------------------------------------------------------------

Definitions
    The Exchange proposes to define certain terms for the trading of 
Nasdaq Bitcoin Index Options in Options 4D, Section 2, titled 
``Definitions.'' The Exchange proposes to utilize certain defined terms 
in Options 4A, Section 1, such as ``aggregate exercise price,'' 
``current index value,'' ``exercise price,'' ``European-style index 
option,'' ``index multiplier,'' and ``reporting authority.''
    Specifically, the term ``aggregate exercise price'' shall be as 
defined within Options 4A, Section 2(a).\29\ The term ``current index 
value'' shall be as defined within Options 4A, Section 2(e).\30\ The 
term ``exercise price'' shall be as defined within Options 4A, Section 
2(f).\31\ The term ``European-style index option'' shall be as defined 
within Options 4A, Section 2(g).\32\ The term ``index multiplier'' 
shall be as defined within Options 4A, Section 2(i).\33\ Finally, the 
term ``reporting authority'' shall be as defined within Options 4A, 
Section 2(o).\34\
---------------------------------------------------------------------------

    \29\ See proposed Options 4D, Section 2(a)(1).
    \30\ See proposed Options 4D, Section 2(a)(2).
    \31\ See proposed Options 4D, Section 2(a)(3).
    \32\ See proposed Options 4D, Section 2(a)(4).
    \33\ See proposed Options 4D, Section 2(a)(5).
    \34\ See proposed Options 4D, Section 2(a)(6).
---------------------------------------------------------------------------

    The Exchange proposes to adopt a new term, ``Constituent 
Exchange,'' in Options 4D, Section 2(a)(2) which shall be defined as a 
cryptocurrency trading venue approved by the CME CF Cryptocurrency 
Pricing Products Oversight Committee to serve as pricing source for the 
calculation of a CME CF Cryptocurrency Reference Rate-New York Variant 
or CME CF Cryptocurrency Real Time Index, collectively known as the CME 
CF Cryptocurrency Pricing Products.\35\ The Exchange proposes to define 
the term ``underlying'' at proposed Options 4D, Section 2(a)(7) with 
respect to Nasdaq Bitcoin Index Options to mean the bitcoin that is the 
basis for the calculation of the index. The Exchange notes that the 
term ``unit of foreign currency'' is defined at Options 4C, Section 
2(b)(4) and also does not refer to a security for the listing of index 
options on foreign currencies.
---------------------------------------------------------------------------

    \35\ Of note, Nasdaq Bitcoin Index Options will have an 
aggregated price derived from Constituent Exchanges, whereas broad-
based indices have components.
---------------------------------------------------------------------------

    The Exchange also proposes to note in Supplementary Material .01 to 
Options

[[Page 10553]]

4C, Section 2 that CF Benchmarks shall be the reporting authority for 
Nasdaq Bitcoin Index Options.
Trading Sessions
    Options 4D, Section 3, titled ``Trading Sessions,'' notes that 
Nasdaq Bitcoin Index Options may be effected on the Exchange between 
the hours of 9:30 a.m. (Eastern time) and 4:15 p.m. (Eastern time), 
except that on the last trading day, transactions in expiring in Nasdaq 
Bitcoin Index Options may be effected on the Exchange between the hours 
of 9:30 a.m. (Eastern time) and 4:00 p.m. (Eastern time). As is the 
case for all index options listed on Phlx, General 3, Rule 1030 governs 
the days the Exchange will be open for business.\36\ These hours are 
consistent with trading hours for index options listed on Phlx.
---------------------------------------------------------------------------

    \36\ See proposed Options 4D, Section 3(a).
---------------------------------------------------------------------------

Designation of an Index
    Unlike other index options, Nasdaq Bitcoin Index Options need not 
meet the requirements of Options 4, Section 3 or Options 4A, Section 
3.\37\ The Exchange does not propose to designate Nasdaq Bitcoin Index 
Options as a broad based, narrow based or sector index. Of note, index 
options on foreign currencies are also not designated as a broad based, 
narrow based or sector index.
---------------------------------------------------------------------------

    \37\ See proposed Options 4D, Section 4.
---------------------------------------------------------------------------

Minimum Increments
    As proposed, Nasdaq Bitcoin Index Options would have a minimum 
increment of $0.01 for all series.\38\ Similar to the Nasdaq 100 Micro 
Index (``XND'') that are based on 1/100th of the value of the Nasdaq-
100 Index, the Exchange proposes this increment given the 1/100th 
relationship to the BRRNY. Nasdaq Bitcoin Index Options would be quoted 
and traded in U.S. dollars.\39\
---------------------------------------------------------------------------

    \38\ See proposed Supplementary Material .06 to Options 3, 
Section 3.
    \39\ Phlx Options 4A, Section 12(a)(1) titled ``Meaning of 
Premium Bids and Offers,'' provides that bids and offers shall be 
expressed in terms of dollars and decimal equivalents of dollars per 
unit of the index (e.g., a bid of 85.50 would represent a bid of 
$85.50 per unit).
---------------------------------------------------------------------------

Position and Exercise Limits
    Generally, Options 9, Section 13 shall govern position limits for 
Nasdaq Bitcoin Index Options, except as modified by this Options 4D, 
Section 6. Position Limits for Nasdaq Bitcoin Index Options shall be 
equal to 250,000 contracts on the same side of the market, restricted 
to no more than 150,000 near-term contracts.\40\ All position limit 
hedge exemptions applicable to broad-based index options would also 
apply to Nasdaq Bitcoin Index Options. Nasdaq Bitcoin Index Options 
contracts would not be aggregated with options contracts. Nasdaq 
Bitcoin Index Options positions in Short Term Option Series, Monthly 
Options Series, and Quarterly Options Series shall be aggregated.\41\ 
The proposed position limits are similar to those applied to broad-
based index options.
---------------------------------------------------------------------------

    \40\ See proposed Options 4D, Section 6(a).
    \41\ See proposed Options 4D, Section 6(b).
---------------------------------------------------------------------------

    Each member or member organization that maintains a position on the 
same side of the market in excess of 100,000 contracts for its own 
account or for the account of a customer in excess of 100,000 contracts 
for its own account or for the account of a customer in Nasdaq Bitcoin 
Index Options, would be required to file a report with the Exchange 
that includes, but is not limited to, data related to the option 
positions, whether such positions are hedged and if applicable, a 
description of the hedge and information concerning collateral used to 
carry the positions. Market Makers would be exempt from this reporting 
requirement.\42\ Finally, exercise limits for index option contracts on 
Nasdaq Bitcoin Index Options shall be equivalent to the position limits 
described in Options 4D, Section 6.\43\ Nasdaq Bitcoin Index Options 
are cash-settled.
---------------------------------------------------------------------------

    \42\ See proposed Options 4D, Section 6(c).
    \43\ See proposed Options 4D, Section 6(d).
---------------------------------------------------------------------------

Terms of Index Options Contracts
    As noted herein, the Exchange proposes to provide for the listing 
and trading of Nasdaq Bitcoin Index Options, a new index that reflects 
the price of bitcoin as represented by the CME CF Bitcoin Real Time 
Index, a once a second benchmark index price for bitcoin that 
aggregates order data from Bitcoin-USD markets operated by major 
cryptocurrency exchanges that conform to the CME CF Constituent 
Exchange Criteria.
    Similar to other index options at Options 4A, Section 12(a)(1), 
bids and offers on Nasdaq Bitcoin Index Options would be expressed in 
terms of dollars and cents per unit of the index.\44\ The Exchange 
shall determine fixed-point intervals of exercise prices for call and 
put options.\45\
---------------------------------------------------------------------------

    \44\ See proposed Options 4D, Section 7(a)(1).
    \45\ See proposed Options 4D, Section 7(a)(2).
---------------------------------------------------------------------------

    As proposed, strike price intervals of no less than $2.50 are 
generally permitted for Nasdaq Bitcoin Index Options, if the strike 
price is less than $200. This is the case today for XND, which is based 
on 1/100th of the value of the Nasdaq-100 Index.\46\ Similar to XND, 
the Exchange may also determine to list strike prices at $1 or greater, 
subject to certain conditions. The Exchange may list series at $1 or 
greater strike price intervals for Nasdaq Bitcoin Index Options and 
will list at least two strike prices above and two strike prices below 
the current value of the Nasdaq Bitcoin Index Options at about the time 
a series is opened for trading on the Exchange. The Exchange shall list 
strike prices for Nasdaq Bitcoin Index Options that are within 5 points 
from the closing value of Nasdaq Bitcoin Index Options on the preceding 
day.\47\
---------------------------------------------------------------------------

    \46\ See proposed Options 4D, Section 7(a)(3).
    \47\ See proposed Options 4D, Section 7(a)(3)(A).
---------------------------------------------------------------------------

    Additional series of the same class of Nasdaq Bitcoin Index Options 
may be opened for trading on the Exchange when the Exchange deems it 
necessary to maintain an orderly market, to meet customer demand or 
when the underlying Nasdaq Bitcoin Index Options moves substantially 
from the initial exercise price or prices. To the extent that any 
additional strike prices are listed by the Exchange, such additional 
strike prices shall be within thirty percent (30%) above or below the 
closing value of Nasdaq Bitcoin Index Options. The Exchange may also 
open additional strike prices that are more than 30% above or below the 
current Nasdaq Bitcoin Index Options value provided that demonstrated 
customer interest exists for such series, as expressed by 
institutional, corporate or individual customers or their brokers. 
Market-Makers trading for their own account shall not be considered 
when determining customer interest under this provision. In addition to 
the initial listed series, the Exchange may list up to sixty (60) 
additional series per expiration month for each series in Nasdaq 
Bitcoin Index Options.\48\
---------------------------------------------------------------------------

    \48\ See proposed Options 4D, Section 7(a)(3)(B).
---------------------------------------------------------------------------

    The Exchange shall not list LEAPS on Nasdaq Bitcoin Index Options 
Nasdaq Bitcoin Index Options at intervals less than $5.\49\
---------------------------------------------------------------------------

    \49\ See proposed Options 4D, Section 7(a)(3)(C).
---------------------------------------------------------------------------

    With respect to delisting, Nasdaq Bitcoin Index Options added 
pursuant Options 4D, Section 7(a)(3)(A) and (B) will be reviewed by the 
Exchange on a monthly basis. The Exchange will review series that are 
outside a range of five (5) strikes above and five (5) strikes below 
the current value Nasdaq Bitcoin Index Options, and delist series with 
no open interest in both the put and the call series having a: (i) 
strike higher than the highest strike price with open interest in the 
put and/or call series for a given expiration month; and (ii) strike

[[Page 10554]]

lower than the lowest strike price with open interest in the put and/or 
call series for a given expiration month.\50\ Notwithstanding this 
delisting policy, customer requests to add strikes and/or maintain 
strikes in Nasdaq Bitcoin Index Options series eligible for delisting 
shall be granted.\51\ If the Exchange identifies series for delisting, 
the Exchange shall notify other options exchanges with similar 
delisting policies regarding eligible series for delisting, and shall 
work with such other exchanges to develop a uniform list of series to 
be delisted, so as to ensure uniform series delisting of multiply 
listed Nasdaq Bitcoin Index Options.\52\
---------------------------------------------------------------------------

    \50\ See proposed Options 4D, Section 7(a)(3)(D).
    \51\ See proposed Options 4D, Section 7(a)(3)(D)(1).
    \52\ See proposed Options 4D, Section 7(a)(3)(D)(2).
---------------------------------------------------------------------------

    Notwithstanding any other provision regarding strike prices in 
Options 4D, Section 6, non-Short Term Options that are on Nasdaq 
Bitcoin Index Options that have been selected to participate in the 
Short Term Option Series Program (referred to as a ``Related non-Short 
Term Option series'') shall be opened during the month prior to 
expiration of such Related non-Short Term Option series in the same 
manner as permitted in Supplementary .01 of Options 4D, Section 6 and 
in the same strike price intervals that are permitted in Supplementary 
.01 of Options 4D, Section 6.\53\ The Exchange proposes to adopt the 
same strike price intervals for Nasdaq Bitcoin Index Options as are 
listed for XND options on Phlx at Supplementary Material .02 to Options 
4A, Section 12.
---------------------------------------------------------------------------

    \53\ See proposed Options 4D, Section 7(a)(3)(E).
---------------------------------------------------------------------------

    As is the case for index options at Options 4A, Section 12(a)(4), 
the Exchange proposes to state that Nasdaq Bitcoin Index Options 
contracts may expire at three (3)-month intervals, in consecutive weeks 
or in consecutive months. The Exchange may list: (i) up to six (6) 
standard monthly expirations at any one time in a class of Nasdaq 
Bitcoin Index Options, but will not list Nasdaq Bitcoin Index Options 
that expire more than twelve (12) months out.\54\
---------------------------------------------------------------------------

    \54\ See proposed Options 4D, Section 7(a)(4).
---------------------------------------------------------------------------

    Nasdaq Bitcoin Index Options would be European-style index 
options.\55\
---------------------------------------------------------------------------

    \55\ See proposed Options 4D, Section 7(a)(5).
---------------------------------------------------------------------------

    Nasdaq Bitcoin Index Options would be P.M.-settled and the exercise 
settlement value would be derived from closing prices on the expiration 
day. The last day of trading for P.M.-settled index options would be 
the business day of expiration, or, in the case of a Nasdaq Bitcoin 
Index Options contract expiring on a day that is not a business day, on 
the last business day before its expiration date. The current index 
value at expiration of Nasdaq Bitcoin Index Options is determined by 
the last reported sale price of each component. In the event that the 
underlying does not open for trading on the expiration date, the price 
of Nasdaq Bitcoin Index Options shall be the last reported sale price 
prior to the expiration date.\56\ The Exchange believes that market 
participants, and in particular, retail investors, prefer P.M.-settled 
index options. P.M.-settlement is preferred by retail investors as it 
allows market participants to hedge their exposure for the full week. 
A.M.-settled options by contrast are based on opening prices on the day 
of expiration and therefore stop trading on the day prior, leaving 
residual risk on the day of expiration. P.M.-settlement is needed to 
garner retail investor support for this product.
---------------------------------------------------------------------------

    \56\ See proposed Options 4D, Section 7(a)(6).
---------------------------------------------------------------------------

    Similar to index options at Options 4A, Section 12(b), after a 
particular class of Nasdaq Bitcoin Index Options has been approved for 
listing and trading on the Exchange, the Exchange shall from time to 
time open for trading series of options therein. Within each approved 
class of Nasdaq Bitcoin Index Options, the Exchange shall open for 
trading a minimum of one expiration month and series for each class of 
approved Nasdaq Bitcoin Index Options and may also open for trading 
series of options having not less than twelve and up to 60 months to 
expiration (``Long-Term Index Options Series'').\57\ Prior to the 
opening of trading in any series of Nasdaq Bitcoin Index Options, the 
Exchange shall fix the expiration month and exercise price of option 
contracts included in each such series.\58\
---------------------------------------------------------------------------

    \57\ See proposed Options 4D, Section 7(b)(2).
    \58\ See proposed Options 4D, Section 7(b).
---------------------------------------------------------------------------

    Also, similar to index options at Options 4A, Section 12(b)(1), 
additional series of Nasdaq Bitcoin Index Options of the same class may 
be opened for trading on the Exchange when the Exchange deems it 
necessary to maintain an orderly market, to meet customer demand or 
when the market price of the underlying index moves more than five 
strike prices from the initial exercise price or prices. The opening of 
a new series of options shall not affect the series of options of the 
same class previously opened. New series of Nasdaq Bitcoin Index 
Options may be added until the beginning of the month in which the 
options contract will expire. Due to unusual market conditions, the 
Exchange, in its discretion, may add a new series of Nasdaq Bitcoin 
Index Options until the fourth business day prior to the business day 
of expiration, or, in the case of Nasdaq Bitcoin Index Options contract 
expiring on a day that is not a business day, up to the fifth business 
day prior to expiration.\59\
---------------------------------------------------------------------------

    \59\ See proposed Options 4D, Section 7(b)(1).
---------------------------------------------------------------------------

    The Exchange would also list Long-Term Option Series or ``LEAPs.'' 
Similar to index options at Options 4A, Section 12(b)(2), the Exchange 
proposes that it may list LEAPs on Nasdaq Bitcoin Index Options that 
expire from twelve (12) to sixty (60) months from the date of issuance. 
There may be up to ten (10) expiration months, none further out than 
sixty (60) months. Strike price intervals and continuity Rules shall 
not apply to such options series until the time to expiration is less 
than twelve (12) months. Bid/ask differentials for LEAPs are specified 
within Options 2, Section 4(b)(4)(i)(A).\60\ Also similar to index 
options at Options 4A, Section 12(b)(1), when new Nasdaq Bitcoin Index 
Options LEAPs are listed, such series would be opened for trading 
either when there is buying or selling interest, or forty (40) minutes 
prior to the close, whichever occurs first. No quotations would be 
posted for such options series until they are opened for trading.\61\
---------------------------------------------------------------------------

    \60\ See proposed Options 4D, Section 7(b)(2)(a).
    \61\ See proposed Options 4D, Section 7(b)(2)(a)(i).
---------------------------------------------------------------------------

    Similar to index options at Options 4A, Section 12(d), the reported 
level of the underlying index that is calculated by the reporting 
authority for purposes of determining the current index value at the 
expiration of Nasdaq Bitcoin Index Options may differ from the level of 
the index that is separately calculated and reported by the reporting 
authority and that reflects trading activity subsequent to the opening 
of trading in the underlying.\62\

---------------------------------------------------------------------------

    The Exchange proposes to note in Supplementary .01 to Options 4D, 
Section 7 that the Short Term Options Series Program listing rules at 
Options 4A, Section 12(b)(4) shall be applicable to Nasdaq Bitcoin 
Index Options. The Monthly Options Series Program at Options 4A, 
Section 12(b)(5) shall be applicable to Nasdaq Bitcoin Index Options. 
Finally, the Quarterly Options Series Program at Options 4A, Section 
12(b)(3) shall be applicable to Nasdaq Bitcoin Index Options. These 
listing rules shall be applicable to an underlying as defined in 
proposed Options 4D, Section 2(a)(7).
    The Exchange proposes to describe the settlement of Nasdaq Bitcoin 
Index Options in Options 4D, Section 9, titled

[[Page 10555]]

``Closing Settlement Value.'' Nasdaq Bitcoin Index Options would be 
settled in U.S. dollars on the business day following expiration. Cash 
settlement would be equal to the difference between the final 
settlement value and the strike price of the contract multiplied by 
$100.\63\
---------------------------------------------------------------------------

    \63\ See proposed Options 4D, Section 8(a).
---------------------------------------------------------------------------

    The Nasdaq Bitcoin Index Options final settlement value would be 
the CME CF Bitcoin Reference Rate--New York Variant (BRRNY) on the 
expiration date (usually a Friday). BRRNY would be divided by a factor 
of one hundred (100) and published as BRRNY--NOS (Nasdaq Options 
Settlement). Nasdaq Bitcoin Index Options will have a multiplier of 
$100.\64\ As noted herein, BRRNY is a once-a-day benchmark index price 
for bitcoin that aggregates trade data from multiple bitcoin-USD 
markets operated by major cryptocurrency exchanges that conform to the 
CME CF Constituent Exchange Criteria. This index price for bitcoin risk 
settlement is synchronized to the traditional U.S. financial market 
close of 1600 New York Time and is calculated every single day of the 
year. BRRNY is a benchmark registered under UK Benchmark Regulations 
and as such is a third country benchmark under the EU BMR Regime. 
Specifically, the BRRNY is calculated based on the Relevant 
Transactions. Relevant Transactions include those that trade bitcoin 
versus U.S. Dollars that occur from 15:00 to 16:00 New York Time on a 
CME CF Constituent Exchange that is reported through its API to the 
Calculation Agent of all CME CF Constituent Exchanges.\65\
---------------------------------------------------------------------------

    \64\ By way of example, if the bitcoin index if 576.97, with a 
$100 multiplier the notional value would be $57,697.00.
    \65\ See proposed Options 4D, Section 8(b).
---------------------------------------------------------------------------

    Settlement is calculated by combining all Relevant Transactions on 
a joint list and recording the trade price and size for each 
transaction. That list is partitioned into a number of equally-sized 
time intervals, of 5 minutes. For each partition \66\ separately, the 
volume-weighted median \67\ trade price is calculated from the trade 
prices and sizes of all Relevant Transactions, i.e., across all 
Constituent Exchanges.\68\ A volume-weighted median differs from a 
standard median in that a weighting factor, in this case trade size, is 
factored into the calculation.\69\ For each partition k, the volume-
weighted median trade prices WM across all Relevant Transactions is 
calculated as:
---------------------------------------------------------------------------

    \66\ CME CF Cryptocurrency Reference Rates are calculated as the 
equally-weighted average of the intermediate calculation steps for 
the K partitions. A single large trade or cluster of trades 
occurring in any one partition will therefore only have a limited 
effect on CME CF Cryptocurrency Reference Rates. See <a href="https://www.cfbenchmarks.com/data/indices/BRRNY">https://www.cfbenchmarks.com/data/indices/BRRNY</a>.
    \67\ Spot prices have historically varied considerably across 
trading venues, in particular during times of high volatility. The 
use of medians to calculate the weighted median trade price for each 
partition (as opposed to averages) greatly reduces CME CF 
Cryptocurrency Reference Rates' susceptibility to price extremes on 
one or more Constituent Exchanges. See <a href="https://www.cfbenchmarks.com/data/indices/BRRNY">https://www.cfbenchmarks.com/data/indices/BRRNY</a>. Trading is driven to some extent by automated 
algorithms that may execute a high number of small trades. The use 
of volume-weighted medians to calculate the weighted median trade 
price for each partition (as opposed to simple medians) assures that 
CME CF Cryptocurrency Reference Rates appropriately reflect large 
trades and that whether an order is executed in parts or in full has 
no effect on calculation results.
    \68\ Partitions are equally-weighted (as opposed to volume-
weighted) to facilitate replication of CME CF Cryptocurrency 
Reference Rates through trading on Constituent Exchanges. Assuming K 
partitions, a trader aiming to transact Y units of the relevant 
cryptocurrency at the CME CF Cryptocurrency Reference Rates can do 
so with little tracking error by transacting Y/K units of the 
cryptocurrency during each partition. See <a href="https://www.cfbenchmarks.com/data/indices/BRRNY">https://www.cfbenchmarks.com/data/indices/BRRNY</a>.
    \69\ See proposed Options 4D, Section 8(b).
    [GRAPHIC] [TIFF OMITTED] TN24FE25.010
    
    The CME CF BRRNY is then given by the equally weighted average of 
the volume-weighted medians of all partitions.\70\ The CME CF 
Cryptocurrency Reference Rate as of the effective time T, CCRR, is then 
given by:
---------------------------------------------------------------------------

    \70\ See proposed Options 4D, Section 8(b).

    Delayed data and missing data are subject to certain rules. Any 
Relevant Transaction for a given Calculation Day that is not available 
from a Constituent Exchange's API by the Retrieval Time is disregarded 
in the calculation of the CME CF Cryptocurrency Reference Rate for that 
Calculation Day. If no Relevant Transaction occurs on a Constituent 
Exchange on a given Calculation Day or one or more Relevant 
Transactions occur but for any reason cannot be retrieved by the 
Calculation Agent, the Constituent Exchange is disregarded in the 
calculation of the CME CF Cryptocurrency Reference Rate for that 
Calculation Day. If, for any of the K partitions of the TWAP Period, no 
Relevant Transaction occurs on any Constituent Exchange or one or more 
Relevant Transactions occur but for any reason cannot be retrieved by 
the Calculation Agent, the partition remains empty and will be 
disregarded in the calculation of the CME CF Cryptocurrency Reference 
Rate for that Calculation Day. The denominator in Eq. 2 above will then 
be decremented by the number of empty partitions. If one or more 
Relevant Transactions occur but for any reason no Relevant Transaction 
can be retrieved from any Constituent Exchange API by the Calculation 
Agent, a CME CF Cryptocurrency Reference Rate calculation failure 
occurs for that Calculation Day. All Relevant

[[Page 10556]]

Transactions retrieved by the Calculation Agent for a given Calculation 
Day are subject to an automated screening for erroneous data.\71\

    The Exchange proposes to adopt ``Disclaimers'' at Options 4D, 
Section 9. As noted herein, CF Benchmarks shall be the reporting 
authority for Nasdaq Bitcoin Index Options.\75\ Other options markets 
provide similar disclaimers for the reporting authority.\76\

---------------------------------------------------------------------------

    The Exchange proposes to provide at Options 4D, Section 9 that no 
reporting authority, and no affiliate of a reporting authority (each 
such reporting authority, its affiliates, and any other entity 
identified in Options 4D, Section 9 are referred to collectively as a 
``Reporting Authority''), makes any warranty, express or implied, as to 
the results to be obtained by any person or entity from the use of an 
index it publishes, any opening, intra-day or closing value therefor, 
or any data included therein or relating thereto, in connection with 
the trading of any options contract based thereon or for any other 
purpose. The Reporting Authority shall obtain information for inclusion 
in, or for use in the calculation of, such index from sources it 
believes to be reliable, but the Reporting Authority does not guarantee 
the accuracy or completeness of such index, any opening, intra-day or 
closing value therefor, or any date included therein or related 
thereto. The Reporting Authority hereby disclaims all warranties of 
merchantability or fitness for a particular purpose or use with respect 
to such index, any opening, intra-day, or closing value therefor, any 
data included therein or relating thereto, or any options contract 
based thereon. The Reporting Authority shall have no liability for any 
damages, claims, losses (including any indirect or consequential 
losses), expenses, or delays, whether direct or indirect, foreseen or 
unforeseen, suffered by any person arising out of any circumstance or 
occurrence relating to the person's use of such index, any opening, 
intra-day or closing value therefor, any data included therein or 
relating thereto, or any options contract based thereon, or arising out 
of any errors or delays in calculating or disseminating such index.
Margin
    The Exchange proposes to apply margin requirements for the purchase 
and sale of Nasdaq Bitcoin Index Options that are identical to those 
applied for its broad-based index options. Therefore, purchases of puts 
or calls with 9 months or less until expiration must be paid for in 
full. Writers of uncovered puts or calls must deposit/maintain 100% of 
the option proceeds plus 15% of the underlying index value less out-of-
the-money amount, if any, to a minimum of option proceeds plus 10% of 
underlying index value for calls; 10% of the put exercise price for 
puts.
Regulatory Rules
    The trading of Nasdaq Bitcoin Index Options would be subject to the 
same rules that presently govern the trading of index options on Phlx, 
including sales practice rules and trading rules. Options 10, Section 
6, ``Opening of Accounts,'' is designed to protect public customer 
trading and shall apply to trading in Nasdaq Bitcoin Index Options. 
Specifically, Options 10, Section 6(a) prohibits members and member 
organizations from accepting a customer order to purchase or write an 
option, including Nasdaq Bitcoin Index Options, unless such customer's 
account has been approved in writing by an Options Principal. 
Additionally, Phlx Options 10, Section 8, ``Suitability of 
Recommendations,'' is designed to ensure that options, including Nasdaq 
Bitcoin Index Options, are only sold to customers capable of evaluating 
and bearing the risks associated with trading in this instrument. 
Further, Phlx Options 10, Section 9, ``Discretionary Accounts,'' 
permits members and member organizations to exercise discretionary 
power with respect to trading options, including Nasdaq Bitcoin Index 
Options, in a customer's account only if the customer has given prior 
written authorization and the account has been accepted in writing by a 
Registered Options Principal. Phlx Options 10, Section 9 also requires 
a record to be made of every option transaction for an account in 
respect to which a member or member organization or a partner, officer 
or employee of a member organization is vested with any discretionary 
authority, such record to include the name of the customer, the 
designation, number of contracts and premium of the option contracts, 
the date and time when such transaction took place and clearly 
reflecting the fact that discretionary authority was exercised. 
Finally, Phlx Options 10, Section 7, ``Supervision of Accounts,'' Phlx 
Options 10, Section 10, ``Confirmations to Customers,'' and Phlx 
Options 10, Section 13, ``Delivery of Options Disclosure Documents and 
Prospectus,'' will also apply to trading in Nasdaq Bitcoin Index 
Options.
    The trading of Nasdaq Bitcoin Index Options will be subject to the 
trading halt procedures applicable to other index options traded on the 
Exchange.\77\
---------------------------------------------------------------------------

    \77\ Phlx Options 4A, Section 18(c), Trading Rotations, Halts or 
Reopenings.

    The Exchange believes that all Phlx and OCC members will be able to 
accommodate trading, clearance and settlement of Nasdaq Bitcoin Index 
Options without alteration.
Surveillance
    In 2024, the Commission approved various rule changes to list and 
trade Spot Bitcoin ETPs.\78\ The Commission noted in the Spot Bitcoin 
ETPs Approval Order that, ``. . . one way an exchange that lists 
bitcoin-based exchange-traded products (``ETPs'') can meet the 
obligation under Exchange Act Section 6(b)(5) that its rules be 
designed to prevent fraudulent and manipulative acts and practices is 
by demonstrating that the exchange has a comprehensive surveillance-
sharing agreement with a regulated market of significant size related 
to the underlying or reference bitcoin assets. Such an agreement would 
assist in detecting and deterring fraud and manipulation related to 
that underlying asset.'' The Commission has recognized that the 
``regulated market of significant size'' standard is not the only means 
for satisfying Section 6(b)(5) of the Act, specifically providing that 
a

[[Page 10557]]

listing exchange could demonstrate that ``other means to prevent 
fraudulent and manipulative acts and practices'' are sufficient to 
justify dispensing with the requisite surveillance-sharing 
agreement.\79\ For example, in approving the Spot Bitcoin ETPs, the 
Commission found that there were ``sufficient `other means' of 
preventing fraud and manipulation,'' including that:
---------------------------------------------------------------------------

    \78\ See supra note 16.
    \79\ See Securities Exchange Act Release No. 83723 (July 26, 
2018), 83 FR 37579 at 37580 (August 1, 2018) (The ``Winklevoss 
Order''). The Commission has also specifically noted that it ``is 
not applying a `cannot be manipulated' standard; instead, the 
Commission is examining whether the proposal meets the requirements 
of the Exchange Act and, pursuant to its Rules of Practice, places 
the burden on the listing exchange to demonstrate the validity of 
its contentions and to establish that the requirements of the 
Exchange Act have been met.'' See Winklevoss Order, 83 FR at 37582.

    [B]ased on the record before the Commission and the improved 
quality of the correlation analysis in the record, including the 
Commission's own analysis, the Commission is able to conclude that 
fraud or manipulation that impacts prices in spot bitcoin markets 
would likely similarly impact CME bitcoin futures prices. And 
because the CME's surveillance can assist in detecting those impacts 
on CME bitcoin futures prices, the Exchanges' comprehensive 
surveillance-sharing agreement with the CME--a U.S. regulated market 
whose bitcoin futures market is consistently highly correlated to 
spot bitcoin, albeit not of ``significant size'' related to spot 
bitcoin--can be reasonably expected to assist in surveilling for 
fraudulent and manipulative acts and practices in the specific 
context of the [Spot Bitcoin ETPs].\80\
---------------------------------------------------------------------------

    \80\ See Spot Bitcoin ETPs Approval Order 89 FR 3010 and 3011.

    As described in the Spot Bitcoin ETPs Approval Order, there is 
currently a regulated U.S. market with respect to spot bitcoin, the CME 
bitcoin futures (``Bitcoin Futures'') market.\81\ In its Spot Bitcoin 
ETPs Approval Order, the Commission found there was a high price 
correlation between the underlying and the futures market.\82\ The 
proposed Nasdaq Bitcoin Index Options and the various Spot Bitcoin ETPs 
reference the same underlying market for spot bitcoin that trade on 
spot bitcoin trading platforms.
---------------------------------------------------------------------------

    \81\ CME began offering trading in Bitcoin Futures in 2017. Each 
contract represents five bitcoin and is based on the CME CF Bitcoin 
Reference Rate. The contracts trade and settle like other cash 
settled commodity futures contracts.
    \82\ A correlation analysis was conducted by the Commission in 
analyzing the Spot Bitcoin ETP proposals. The results of the 
Commission's analysis confirmed that the CME bitcoin futures market 
has been consistently highly correlated with the subset of the spot 
bitcoin market utilized in the analysis for the timeframe reviewed. 
See Spot Bitcoin ETPs Approval Order at 89 FR 3010.
---------------------------------------------------------------------------

    Specifically, the Exchange has a comprehensive surveillance-sharing 
agreement with the CME via its common membership in ISG, which 
facilitates the sharing of information that is available to the CME 
through its surveillance of its markets, including its surveillance of 
the Bitcoin Futures market. Similar to the Spot Bitcoin ETPs previously 
approved by the SEC, Nasdaq's ability to obtain information regarding 
trading in the Bitcoin Futures market from other markets that are 
members of the ISG (specifically the CME) would assist Nasdaq in 
detecting and deterring misconduct.
    Further, the exchanges that list Spot Bitcoin ETPs comprehensively 
surveil market conditions and price movements on a real time and 
ongoing basis in order to detect and prevent price distortions, 
including price distortions caused by manipulative efforts. Thus, the 
CME's surveillance as well as Nasdaq's surveillance and other equity 
markets that list Spot Bitcoin ETPs can reasonably be relied upon to 
capture the effects on the Bitcoin Futures market and Spot Bitcoin 
ETPs, as applicable, that are caused by a person attempting to 
manipulate the futures ETP or Spot Bitcoin ETPs by manipulating the 
price of bitcoin futures contracts or Spot Bitcoin ETPs, whether that 
attempt is made by directly trading on the Bitcoin Futures market or 
Spot Bitcoin ETPs, or indirectly by trading outside of the Bitcoin 
Futures market or Spot Bitcoin ETPs.
    The Exchange would have an adequate surveillance program in place 
for Nasdaq Bitcoin Index Options as it intends to apply the same 
program procedures that it applies to the Exchange's other index 
options products.\83\ Index products and their respective symbols are 
integrated into the Exchange's existing surveillance system 
architecture and are thus subject to the relevant surveillance 
processes. This is true for both surveillance system processing and 
manual processes that support the Phlx's surveillance program. 
Additionally, the Exchange is also a member of the Intermarket 
Surveillance Group (``ISG'') under the Intermarket Surveillance Group 
Agreement. ISG members work together to coordinate surveillance and 
investigative information sharing in the stock and options markets. 
Both the Exchange and CME are members of ISG.\84\
---------------------------------------------------------------------------

    \83\ The surveillance program includes real-time patterns for 
price and volume movements and post-trade surveillance patterns 
(e.g., spoofing, marking the close, pinging, phishing).
    \84\ For a list of the current members and affiliate members of 
ISG, see <a href="https://www.isgportal.com/">https://www.isgportal.com/</a>.
---------------------------------------------------------------------------

    The Exchange, in its normal course of surveillance, will monitor 
for any potential manipulation of the Nasdaq Bitcoin Index Options 
settlement value according to the Exchange's current procedures. The 
Exchange believes that its surveillance procedures currently in place 
will allow it to adequately surveil for any potential manipulation in 
the trading of Nasdaq Bitcoin Index Options.
Capacity
    The Exchange represents that it has the necessary system capacity 
to support additional quotations and messages that will result from the 
listing and trading Nasdaq Bitcoin Index Options. Finally, the Options 
Price Reporting Authority (``OPRA'') has the necessary systems capacity 
to handle the additional traffic associated with the listing of Nasdaq 
Bitcoin Index Options. The proposal is limited to one new class and the 
additional traffic that would be generated from the introduction of 
Nasdaq Bitcoin Index Options would be manageable and well within any 
systems capacity capabilities.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\85\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\86\ in particular, in that it will permit trading 
in Nasdaq Bitcoin Index Options pursuant to rules designed to prevent 
fraudulent and manipulative acts and practices and promote just and 
equitable principles of trade. In particular, the Exchange believes the 
proposed rule change will further the Exchange's goal of introducing 
new and innovative products to the marketplace. The Exchange believes 
that listing Nasdaq Bitcoin Index Options will provide an opportunity 
for investors to hedge, or speculate on, the market risk associated 
with trading bitcoin. This proposal offers market participants with 
choice of product structures for bitcoin exposure and offers a flexible 
way to gain exposure to bitcoin through transparent, regulated index 
options.

---------------------------------------------------------------------------

    In 2006, Phlx received approval to list and trade foreign currency 
index options.\87\ These foreign currency options are cash-settled, 
European-styled options, issued by OCC that permit holders to receive 
U.S. dollars representing the difference between the current foreign 
exchange spot price and

[[Page 10558]]

the exercise price of the option.\88\ Further, similar to this 
proposal, Phlx noted in its rule change seeking approval for foreign 
currency options (or ``U.S. dollar-settled FCOs'') that ``U.S. dollar-
settled FCOs would trade in the same general manner as equity index 
options, which are also U.S. dollar-settled products.'' \89\ The 
Commission noted in the SR-Phlx-2006-34 approval order that it believed 
that, ``. . . . sufficient venues exist for obtaining reliable 
information on the Currencies so that investors in U.S. dollar-settled 
FCOs can monitor the underlying spot market in the Currencies. The 
Commission also believes that the Phlx's procedures and the competitive 
nature of the spot market for the [c]urrencies should help to ensure 
that the settlement values for U.S. dollar-settled FCO contracts will 
accurately reflect the spot price for foreign currencies . . .''.\90\

    Foreign currency options established precedent to list and trade 
index options overlying an underlying that is not a security, such as 
proposed herein. Like foreign currency markets, the bitcoin market is 
liquid and is characterized by a significant degree of volume and 
turnover. As a result, the Exchange believes that sufficient venues 
exist to provide investors with ready access to reliable information on 
the price of bitcoin for purposes of this product.\91\ While bitcoin is 
a novel asset, the requirements of a benchmark price for bitcoin are no 
different from those required of a benchmark price for any asset.
---------------------------------------------------------------------------

    \91\ Today, there are regulated bitcoin futures and options on 
futures derivatives contracts from CME Group and Eurex AG, approved 
regulated spot FTSE Bitcoin Index futures as well as a variety of 
other regulated exchange traded products and funds in Canada, 
Brazil, Hong Kong and Europe.
---------------------------------------------------------------------------

    The introduction of Nasdaq Bitcoin Index Options will provide 
investors with an additional tool to manage their portfolio, whether by 
hedging or through diversification and will remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system and, in general, protect investors because offering this new 
product will provide investors with a greater opportunity to realize 
the benefits of utilizing index options based on spot bitcoin, 
including cost efficiencies and increased hedging strategies. In 
particular, the Exchange believes that offering options Nasdaq Bitcoin 
Index Options will benefit investors by providing them with an 
additional, relatively lower cost risk management tool allowing them to 
manage, more easily, their positions and associated risks, in their 
portfolios in connection with exposure to spot bitcoin. Additionally, 
this cash-settled index that permits holders to receive U.S. dollars 
representing the difference between the current bitcoin spot market and 
the exercise price of the option eliminates risks associated with 
physical settlement such as volatility and movement in the underlying 
at expiration. Today, the CME CF Bitcoin Reference Rate--New York 
Variant for the Bitcoin--U.S. Dollar trading pair (the ``CF Benchmarks 
Index'') constitutes the index for the following products: iShares 
Bitcoin Trust ETF, Franklin Bitcoin ETF, Bitwise Bitcoin ETF, Valkyrie 
Bitcoin Fund and ARK 21Shares Bitcoin ETF.
    For the reasons which follow, the Exchange believes that Nasdaq 
Bitcoin Index Options is designed to prevent fraudulent and 
manipulative acts and practices and promote just and equitable 
principles of trade. Nasdaq Bitcoin Index Options are representative of 
the underlying market, resistant to manipulation, and replicable by 
market participants, to be able to foster further institutional 
participation in the underlying market that is being measured. The 
final settlement value for Nasdaq Bitcoin Index Options would be the 
CME CF Bitcoin Reference Rate--New York Variant (BRRNY) on the 
expiration date (usually a Friday). BRRNY will be divided by a factor 
of one hundred (100) to create a new settlement value to arrive at the 
settlement value for Nasdaq Bitcoin Index Options and will be published 
as BRRNY--NOS (Nasdaq Options Settlement). BRRNY is a once-a-day 
benchmark index price for bitcoin that aggregates trade data from 
multiple bitcoin-USD markets operated by major cryptocurrency exchanges 
that conform to the CME CF Constituent Exchange Criteria. It is 
synchronized to the traditional U.S. financial market close of 1600 New 
York Time and is calculated every single day of the year. The index is 
a Registered Benchmark under UK BMR and as such is a Third Country 
benchmark under the EU BMR Regime.
    The BRRNY index is methodologically identical to the regulated CME 
CF Bitcoin Reference Rate (BRR), the most widely used benchmark price 
for Bitcoin, that settles the Bitcoin-USD derivatives complex listed by 
CME Group, and which serves as the NAV for exchange listed investment 
products from WisdomTree Europe, Evolve ETFs (CAN) and QR Asset 
Management (BRZ). The only difference between the CME CF BRRNY and the 
CME CF BRR, is that BRRNY references the price of bitcoin at the 
closing time of U.S. markets, 16:00 New York Time, rather than the 
price at 16:00 London Time, referenced by the BRR.
    The purpose of BRRNY is to provide a replicable, manipulation-
resistant and representative bitcoin benchmark that synchronizes with 
the traditional U.S. market close. The CME CF Bitcoin Reference Rate--
New York Variant is a regulated Benchmark under the UK Benchmarks 
Regulation (BMR) regime. The BRRNY calculation methodology aggregates 
transactions of Bitcoins in U.S. dollars that are only conducted on the 
most liquid markets for which data is publicly available and operated 
by exchanges that meet the CME CF Constituent Exchange Criteria.\92\
---------------------------------------------------------------------------

    \92\ See supra note 25.
---------------------------------------------------------------------------

    BRRNY is a valid and robust benchmark that is calculated from input 
data of sufficient volume so that it is representative of the market it 
seeks to measure. Additionally, BRRNY has volume sufficiency which 
permits it be replicated by institutional market participants and 
product providers that need to warehouse price risk. The below table 
summarizes the total number of transactions and average number of 
transactions per day observed each month for BRRNY.\93\ Between 
February 28, 2022, and January 31, 2024 (weekdays only), on average 
2,116.73 Bitcoins, or $59M were traded during each daily observation 
window between 15:00 and 16:00 New York Time.\94\
---------------------------------------------------------------------------

    \93\ The data represents both trade count and bitcoin volume 
during the observation window.

    This trading activity exhibits volatility that is not substantially 
different from that shown in traditional asset markets. The volume 
observed and the reliability of that volume are clearly evident to be 
sufficient for the calculation of a robust and reliable benchmark.
    Phlx believes that Nasdaq Bitcoin Index Options will be utilized 
for a wide range of activities such as asset valuation, settlement of 
financial risk, risk management, NAV calculation, unit creation and 
unit redemption. To that end, the index design is fair and transparent. 
CF Benchmarks exclusively sources input data from Constituent Exchanges 
that meet published criteria as set out in its Constituent Exchanges 
Criteria and conducts a thorough review of any exchange under 
consideration for inclusion as a Constituent Exchange.\95\ BRRNY 
methodology takes an observation period and divides it into equal 
partitions of time. The volume-weighted median of all transactions 
within each partition is then calculated. The benchmark index value is 
determined from the arithmetic mean of the volume-weighted medians, 
equally weighted. As a result, individual trades of large size have 
limited effect on the index level as they only influence the level of 
the volume-weighted median for that specific partition. Further, a 
cluster of trades in a short period of time will also only influence 
the volume-weighted median of the partition or partitions they were 
conducted in, thereby limiting impact. Use of volume-weighted medians 
as opposed to volume-weighted means ensures that transactions conducted 
at outlying prices do not have an undue effect on the value of a 
specific partition. By not volume weighting partitions, trades of large 
size or clusters of trades over a short period of time will not have an 
undue influence on the index level. CF Benchmarks applies equal weight 
to transactions observed from CME CF Constituent Exchanges. With no 
pre-set weights, the BRRNY index is not readily subject to 
manipulation. Using the arithmetic mean of partitions of equal weight 
further denudes the effect of trades of large size at prices that 
deviate from the prevailing price having undue influence on the 
benchmark level.\96\
---------------------------------------------------------------------------

    \95\ The criteria are available at: <a href="https://docs.cfbenchmarks.com/CME%20CF%20Constituent%20Exchanges%20Criteria.pdf">https://docs.cfbenchmarks.com/CME%20CF%20Constituent%20Exchanges%20Criteria.pdf</a>. The arrangements 
of all Constituent Exchanges are reviewed annually to ensure that 
they continue to meet all criteria specified within ``Constituent 
Exchange Criteria.'' This due diligence is documented, and the 
information is distributed to CF Benchmarks' oversight organs to 
consider. The deliberations of oversight organs are conducted during 
regular meetings, minutes of such meetings are publicly available, 
being published by the Administrator on its website.

---------------------------------------------------------------------------

    BRRNY's methodology incorporates a procedure for potentially 
erroneous data. Although volume-weighted medians of transaction prices 
from individual data sources are not part of the benchmark 
determination process, they are calculated as a means of quality 
control and manipulation resistance. In the event of an instance of 
index calculation in which a Constituent Exchange's volume-weighted 
median transaction price exhibits an absolute percentage deviation from 
the volume-weighted median price of other Constituent Exchange 
transactions greater than the Potentially Erroneous Data Parameter 
(10%), then transactions from that Constituent Exchange are deemed 
potentially erroneous and excluded from the index calculation. All 
instances of data excluded from a calculation trigger a Benchmark 
Surveillance Alert that is investigated. By way of example, between 
February 28, 2022, and January 31, 2024, the Potentially Erroneous Data 
Parameter of the methodology for the CME CF Bitcoin Reference Rate--New 
York Variant has never been triggered. Analysis of the max volume-
weighted median per exchange during the observation period produced the 
results in the table. The results illustrate that during the 
observation period, no Constituent Exchange's input data needed to be 
excluded due to exhibiting potential manipulation and indeed no 
individual cryptocurrency exchange exhibits a deviation percentage 
above 2.41% during this period.

    CF Benchmarks has implemented a benchmark surveillance program for 
the investigation of alerts. Instances of suspected benchmark 
manipulation are escalated through appropriate regulatory channels in 
accordance with CF Benchmarks' obligations under the UK Benchmarks 
Regulation (UK BMR). As a regulated Benchmark Administrator, CF 
Benchmarks is subject to supervision by the UK FCA.\97\
---------------------------------------------------------------------------

    \97\ Furthermore, CF Benchmarks' Control Procedures with respect 
to compliance with the UK BMR have been audited by `Big Four' 
accountancy firm Deloitte. The Independent Assurance Report on 
Control Procedures Noted by CF Benchmarks Regarding Compliance with 
the UK Benchmarks Regulation as ofSeptember 12, 2022 is available 
at: <a href="https://docs.cfbenchmarks.com/Deloitte_CF%20Benchmarks%20SOC1%20Audit%20Report.pdf">https://docs.cfbenchmarks.com/Deloitte_CF%20Benchmarks%20SOC1%20Audit%20Report.pdf</a>.
---------------------------------------------------------------------------

    In terms of correlation, an analysis was undertaken of the pair-
wise correlation of prices from Constituent Exchanges on a per-minute 
basis (the price difference between transactions for each minute at 
each exchange) during the observation period. The results are shown in 
the below table.

    With respect to replicability, a simple replication simulation was 
thereby conducted of BRRNY to demonstrate the extent of slippage that 
implementation of the BRR would probably encounter. The methodology was 
as follows for weekdays only.
    [ssquf] Trades are executed on n (6) Constituent Exchanges, during 
a 3,600-second window.
    [ssquf] One trade is executed every second and the price achieved 
is assumed to be the last execution price observed in that second. Its 
associated volume is assumed to be the volume executed during that 
second.
    [ssquf] If no trade is completed in any single-second period, then 
the price achieved is assumed to be the price achieved in the previous 
second, but the associated volume from the previous second is not added 
to the volume executed in the latest second.
    The results of this simulation are displayed below.
    [GRAPHIC] [TIFF OMITTED] TN24FE25.015
    
    Summary data for the above simulation is provided below.
    [GRAPHIC] [TIFF OMITTED] TN24FE25.016
    
    As evidenced above, the BRRNY can be replicated with a high degree 
of confidence and usually with slippage of no more than 1 basis point 
(0.01%). On only 6.76% of days would slippage have been greater than 5 
basis points (0.05%). Indeed, even on the most volatile day, slippage 
was approximately one half of one percent, 51.6 basis points (0.516%). 
Furthermore, in the 24-month period under observation slippage would 
have been in double-digit basis points only 10 times.
    In 2024, the Commission approved various rule changes to list and 
trade Spot Bitcoin ETPs.\98\ The Commission noted in the Spot Bitcoin 
ETPs Approval Order that, ``. . . one way an exchange that lists 
bitcoin-based exchange-traded products (``ETPs'') can meet the 
obligation under Exchange Act Section 6(b)(5) that its rules be 
designed to prevent fraudulent and manipulative acts and practices is 
by demonstrating that the exchange has a comprehensive surveillance-
sharing agreement with a regulated market of significant size related 
to the underlying or reference bitcoin assets. Such an agreement would 
assist in detecting and deterring fraud and manipulation related to 
that underlying asset.'' The Commission has recognized that the 
``regulated market of significant size'' standard is not the only means 
for satisfying Section 6(b)(5) of the Act, specifically providing that 
a listing exchange could demonstrate that ``other means to prevent 
fraudulent and manipulative acts and practices'' are sufficient to 
justify dispensing with the requisite surveillance-sharing 
agreement.\99\ For example, in approving the Spot Bitcoin ETPs, the 
Commission found that there were ``sufficient `other means' of 
preventing fraud and manipulation,'' including that:
---------------------------------------------------------------------------

    \98\ See supra note 16.
    \99\ See Securities Exchange Act Release No. 83723 (July 26, 
2018), 83 FR 37579 at 37580 (August 1, 2018) (the ``Winklevoss 
Order''). The Commission has also specifically noted that it ``is 
not applying a `cannot be manipulated' standard; instead, the 
Commission is examining whether the proposal meets the requirements 
of the Exchange Act and, pursuant to its Rules of Practice, places 
the burden on the listing exchange to demonstrate the validity of 
its contentions and to establish that the requirements of the 
Exchange Act have been met.'' See Winklevoss Order, 83 FR at 37582.

    [B]ased on the record before the Commission and the improved 
quality of the correlation analysis in the record, including the 
Commission's own analysis, the Commission is able to conclude that 
fraud or manipulation that impacts prices in spot bitcoin markets 
would likely similarly impact CME bitcoin futures prices. And 
because the CME's surveillance can assist in detecting those impacts 
on CME bitcoin futures prices, the Exchanges' comprehensive 
surveillance-sharing agreement with the CME--a U.S. regulated market 
whose bitcoin futures market is consistently highly correlated to 
spot bitcoin, albeit not of ``significant size'' related to spot 
bitcoin--can be reasonably expected to assist in surveilling for 
fraudulent and manipulative acts and practices in the specific 
context of the [Spot Bitcoin ETPs].\100\
---------------------------------------------------------------------------

    \100\ See Spot Bitcoin ETPs Approval Order 89 FR 3010 and 3011.

    As described in the Spot Bitcoin ETPs Approval Order, there is 
currently a regulated U.S. market with respect to spot bitcoin, the CME 
bitcoin futures (``Bitcoin Futures'') market.\101\ In its Spot Bitcoin 
ETPs Approval Order, the Commission found there was a high price 
correlation between the underlying and the futures market.\102\ The 
proposed Nasdaq Bitcoin Index Options and the various Spot Bitcoin ETPs 
reference the same underlying market for spot bitcoin that trade on 
spot bitcoin trading platforms.
---------------------------------------------------------------------------

    \101\ CME began offering trading in Bitcoin Futures in 2017. 
Each contract represents five bitcoin and is based on the CME CF 
Bitcoin Reference Rate. The contracts trade and settle like other 
cash settled commodity futures contracts.
    \102\ A correlation analysis was conducted by the Commission in 
analyzing the Spot Bitcoin ETP proposals. The results of the 
Commission's analysis confirmed that the CME bitcoin futures market 
has been consistently highly correlated with the subset of the spot 
bitcoin market utilized in the analysis for the timeframe reviewed. 
See Spot Bitcoin ETPs Approval Order at 89 FR 3010.
---------------------------------------------------------------------------

    Specifically, the Exchange has a comprehensive surveillance-sharing 
agreement with the CME via its common membership in ISG, which 
facilitates

[[Page 10562]]

the sharing of information that is available to the CME through its 
surveillance of its markets, including its surveillance of the Bitcoin 
Futures market. Similar to the Spot Bitcoin ETPs previously approved by 
the SEC, Nasdaq's ability to obtain information regarding trading in 
the Bitcoin Futures market from other markets that are members of the 
ISG (specifically the CME) would assist Nasdaq in detecting and 
deterring misconduct.
    Further, the exchanges that list Spot Bitcoin ETPs comprehensively 
surveil market conditions and price movements on a real time and 
ongoing basis in order to detect and prevent price distortions, 
including price distortions caused by manipulative efforts. Thus, the 
CME's surveillance as well as Nasdaq's surveillance and other equity 
markets that list Spot Bitcoin ETPs can reasonably be relied upon to 
capture the effects on the Bitcoin Futures market and Spot Bitcoin 
ETPs, as applicable, that are caused by a person attempting to 
manipulate the futures ETP or Spot Bitcoin ETPs by manipulating the 
price of bitcoin futures contracts or Spot Bitcoin ETPs, whether that 
attempt is made by directly trading on the Bitcoin Futures market or 
Spot Bitcoin ETPs, or indirectly by trading outside of the Bitcoin 
Futures market or Spot Bitcoin ETPs.
    The Exchange would have an adequate surveillance program in place 
for Nasdaq Bitcoin Index Options as it intends to apply the same 
program procedures that it applies to the Exchange's other index 
options products.\103\ Index products and their respective symbols are 
integrated into the Exchange's existing surveillance system 
architecture and are thus subject to the relevant surveillance 
processes. This is true for both surveillance system processing and 
manual processes that support the Phlx's surveillance program. 
Additionally, the Exchange is also a member of the Intermarket 
Surveillance Group (``ISG'') under the Intermarket Surveillance Group 
Agreement. ISG members work together to coordinate surveillance and 
investigative information sharing in the stock and options markets. 
Both the Exchange and CME are members of ISG.\104\
---------------------------------------------------------------------------

    \103\ The surveillance program includes real-time patterns for 
price and volume movements and post-trade surveillance patterns 
(e.g., spoofing, marking the close, pinging, phishing).
    \104\ For a list of the current members and affiliate members of 
ISG, see <a href="https://www.isgportal.com/">https://www.isgportal.com/</a>.
---------------------------------------------------------------------------

    The Exchange, in its normal course of surveillance, will monitor 
for any potential manipulation of the Nasdaq Bitcoin Index Options 
settlement value according to the Exchange's current procedures. The 
Exchange believes that its surveillance procedures currently in place 
will allow it to adequately surveil for any potential manipulation in 
the trading of Nasdaq Bitcoin Index Options.
    The Exchange believes that the proposed contract specifications 
will be attractive to market participants, and will remove impediments 
to and perfect the mechanism of a free and open market and a national 
market system. The proposal is designed to ensure that Nasdaq Bitcoin 
Index Options are listed and traded under the same terms that apply to 
other index options that are currently traded on the Exchange. Nasdaq 
Bitcoin Index Options will be subject to the same rules that presently 
govern the trading of index options, including sales practice rules, 
margin requirements, trading rules, and position and exercise limits. 
The proposed product is a cash-settled index option that permit holders 
to receive U.S. dollars representing the difference between the current 
bitcoin spot market and the exercise price of the option and would not 
involve holding physical bitcoin similar to the Spot Bitcoin ETPs, 
which entailed the custody of bitcoin assets. The Exchange's proposal 
to have a minimum increment of $0.01 for all series, similar to XND, 
which is also based on 1/100th of the value of the Nasdaq-100 Index, 
will enable traders to make the most effective use of the product for 
trading and hedging purposes. Nasdaq Bitcoin Index options would be 
P.M.-settled and the exercise settlement value would be derived from 
closing prices on the expiration day. The Exchange believes that 
providing P.M.-settlement will make this product more attractive to 
market participants and help garner additional support for this new 
index options product. In particular, retail investors, prefer P.M.-
settled index options. P.M.-settlement is preferred by retail investors 
as it allows market participants to hedge their exposure for the full 
week. A.M.-settled options by contrast are based on opening prices on 
the day of expiration and therefore stop trading on the day prior, 
leaving residual risk on the day of expiration. Weekly expirations and 
EOMs should create greater trading and hedging opportunities and 
flexibility, and provide customers with the ability to tailor their 
investment objectives more closely. Additionally, position limits for 
Nasdaq Bitcoin Index Options would be equal to 250,000 contracts on the 
same side of the market, restricted to no more than 150,000 near-term 
contracts.\105\ All position limit hedge exemptions applicable to 
broad-based index options would also apply to Nasdaq Bitcoin Index 
Options. The proposed position limits are similar to those applied to 
broad-based index options. Finaly, this proprietary index would be 
cash-settled. The Exchange therefore believes that the rules applicable 
to trading in Nasdaq Bitcoin Index Options are consistent with the 
protection of investors and the public interest.
---------------------------------------------------------------------------

    \105\ See proposed Options 4D, Section 6(a).
---------------------------------------------------------------------------

    Finally, the Exchange represents that it and OPRA have the 
necessary system capacity to support additional quotations and messages 
that will result from the listing and trading Nasdaq Bitcoin Index 
Options.

B. Self-Regulatory Organization's Statement on Burden on Competition

    This proposed rule change does not impose any burden on competition 
that is not necessary or appropriate in furtherance of the purposes of 
the Act. The Exchange notes that the proposed rule change will 
facilitate the listing and trading of an index option product with a 
novel structure that will enhance competition among market 
participants, to the benefit of investors and the marketplace.
    The Exchange does not believe that the proposed rule change will 
impose any burden on intramarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act as Nasdaq Bitcoin 
Index Options would be subject to Exchange rules that currently govern 
the listing and trading of index options, including permissible 
expirations, strike prices, minimum increments, position and exercise 
limits, and margin requirements. Nasdaq Bitcoin Index Options will be 
equally available to all market participants who wish to trade such 
options.
    The Exchange does not believe the proposal will impose any burden 
on intermarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. To the extent that permitting 
Nasdaq Bitcoin Index Options to trade on the Exchange may make Phlx a 
more attractive marketplace to market participants, such market 
participants are free to elect to become market participants on the 
Exchange. Additionally, other options exchanges are free to amend their 
rules, as applicable, to permit them to list and trade index options 
that track the value of bitcoin. The Exchange believes that the 
proposed rule change may relieve any burden on, or otherwise promote, 
competition, as it is designed to increase competition for order flow 
on the Exchange in a manner that is beneficial to investors by 
providing them with a

[[Page 10563]]

relatively low-cost means to hedge their portfolios and meet their 
investment needs in connection with spot bitcoin prices and bitcoin-
related products and positions, in a cash-settled product. The Exchange 
notes that it operates in a highly competitive market in which market 
participants can readily direct order flow to competing venues that 
offer similar products.
