I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to amend Exchange Rule 307, Position Limits, 
and Exchange Rule 309, Exercise Limits to increase the position and 
exercise limits for iShares Bitcoin Trust ETF (``IBIT'').
    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://www.miaxglobal.com/markets/us-options/miax-options/rule-filings">https://www.miaxglobal.com/markets/us-options/miax-options/rule-filings</a>, and at MIAX's principal office.

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 amend Exchange Rule 307, Position Limits, 
and Exchange Rule 309, Exercise Limits,\3\ to permit IBIT to increase 
its position and exercise limits for options on IBIT from 25,000 
contracts by removing IBIT from Interpretation and Policy .01 to 
Exchange Rule 307 and Interpretation and Policy .01 to Exchange Rule 
309. This is a competitive filing based on a similar proposal submitted 
by Nasdaq ISE, LLC (``ISE'') and approved by the Securities and 
Exchange Commission (``Commission'').\4\
---------------------------------------------------------------------------

    \3\ The Exchange notes that all the rules of Chapter III of 
MIAX, including Rules 307 and 309, are incorporated by reference 
into the rulebooks of MIAX Emerald, LLC, MIAX Pearl, LLC and MIAX 
Sapphire, LLC.
    \4\ See Securities Exchange Act Release No. 103564 (July 29, 
2025) (SR-ISE-2024-62) (Self-Regulatory Organizations; Nasdaq ISE, 
LLC; Order Approving a Proposed Rule Change, as Modified by 
Amendment Nos. 2 and 3, Regarding Position and Exercise Limits for 
Options on the iShares Bitcoin Trust ETF)(``ISE Approval Order'').
---------------------------------------------------------------------------

    IBIT is an Exchange-Traded Funds (``ETF'') that holds bitcoin and 
is listed on the Nasdaq Stock Market LLC.\5\ In November 2024, the 
Exchange received approval to list options on IBIT.\6\ The position and 
exercise limits for IBIT options are 25,000 contracts as stated in 
Interpretation and Policy .01 to Exchange Rule 307, Position Limits, 
and Interpretation and Policy .01 to Exchange Rule 309, Exercise Limits 
the lowest limit available in options.\7\
---------------------------------------------------------------------------

    \5\ Nasdaq received approval to list and trade Bitcoin-Based 
Commodity-Based Trust Shares in IBIT pursuant to Rule 5711(d) of 
Nasdaq. See Securities Exchange Act Release No. 99306 (January 10, 
2024), 89 FR 3008 (January 17, 2024) (SR-NASDAQ-2023-016) (Order 
Granting Accelerated Approval of Proposed Rule Changes, as Modified 
by Amendments Thereto, To List and Trade Bitcoin-Based Commodity-
Based Trust Shares and Trust Units). IBIT started trading on January 
11, 2024.
    \6\ See Securities Exchange Act Release No. 101698 (November 21, 
2024), 89 FR 93802 (November 27, 2024) (SR-MIAX-2024-40) (Self-
Regulatory Organizations; MIAX Exchange LLC; Notice of Filing and 
Immediate Effectiveness of a Proposed Rule Change To Amend Exchange 
Rule 402, Criteria for Underlying Securities, Exchange Rule 307, 
Position Limits, and Exchange Rule 309, Exercise Limits To Allow the 
Exchange To List and Trade Options on the iShares Bitcoin Trust (the 
``Trust''))(``IBIT Approval Order''). The Exchange began trading 
IBIT options on November 20, 2024.
    \7\ Options on Fidelity Wise Origin Bitcoin Fund, ARK 21Shares 
Bitcoin ETF, Grayscale Bitcoin Trust (BTC), Grayscale Bitcoin Mini 
Trust BTC, and Bitwise Bitcoin ETF are also subject to a 25,000 
contract position and exercise limit.
---------------------------------------------------------------------------

    Per the Commission ``rules regarding position and exercise limits 
are intended to prevent the establishment of options positions that can 
be used or might create incentives to manipulate or disrupt the 
underlying market so as to benefit the options positions.'' \8\ For 
this reason, the Commission requires that ``position and exercise 
limits must be sufficient to prevent investors from disrupting the 
market for the underlying security by acquiring and exercising a number 
of options contracts disproportionate to the deliverable supply and 
average trading volume of the underlying security.'' \9\ Based on its 
review of the data and analysis provided by the Exchange, the 
Commission concluded that the 25,000 contract position limit for IBIT 
options satisfied these objectives.\10\
---------------------------------------------------------------------------

    \8\ See supra note 6, IBIT Approval Order, 89 FR 78946.
    \9\ See id.
    \10\ See id.
---------------------------------------------------------------------------

    While the Exchange proposed an aggregated 25,000 contract position 
limit for IBIT options in its IBIT Approval Order, it nonetheless 
believed that evidence existed to support a much higher position limit. 
Specifically, the Commission has considered and reviewed the Exchange's 
analysis and ISE's analysis as it was presented by the Exchange in the 
IBIT Approval Order that the exercisable risk associated with a 
position limit of 25,000 contracts represented only 0.4% of the 
outstanding shares of IBIT.\11\ The Commission also has considered and 
reviewed the Exchange's statement its IBIT Approval Order that with a 
position limit of 25,000 contracts on the same side of the market and 
611,040,000 shares of IBIT outstanding, 244 market participants would 
have to simultaneously exercise their positions to place IBIT under 
stress.\12\ Based on the Commission's review of this information and 
analysis, the Commission concluded that the proposed position and 
exercise limits of 25,000 contracts were designed to prevent investors 
from disrupting the market for the underlying security by acquiring and 
exercising a number of options contracts disproportionate to the 
deliverable supply and average trading volume of the underlying 
security, and to prevent the establishment of options positions that 
can be used or might create incentives to manipulate or disrupt the 
underlying market so as to benefit the options position.\13\

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

    IBIT currently qualifies for a 250,000 contract position limit 
pursuant to the criteria in Exchange Rule 307(d)(5), which requires 
that, for the most recent six-month period, trading volume for the 
underlying security be at least 100 million shares.\14\ As of November 
25, 2024, the market capitalization for IBIT was $46,783,480,800 \15\ 
with an average daily volume (``ADV''), for the preceding three months 
prior to November 25, 2024, of 39,421,877 shares. IBIT is well above 
the requisite minimum of 100 million shares necessary to qualify for 
the 250,000 contract position limit. Also, as of November 25, 2024, 
there are 19,787,762 bitcoins in circulation.\16\ According to 
calculations done by ISE as presented in Amendment No. 2,\17\ at

[[Page 38523]]

a price of $94,830,\18\ that equates to a market capitalization of 
greater than $1.876 trillion US. If a position limit of 250,000 
contracts were considered, the exercisable risk would represent 2.89% 
\19\ of the outstanding shares outstanding of IBIT. Given IBIT's 
liquidity, the current 25,000 position limit is extremely conservative.
---------------------------------------------------------------------------

    \14\ Exchange Rule 307, Position Limits, provides at 
subparagraph (d)(5) that to be eligible for the 250,000 contract 
limit, either the most recent six (6) month trading volume of the 
underlying security must have totaled at least 100 million shares or 
the most recent six (6) month trading volume of the underlying 
security must have totaled at least seventy-five (75) million shares 
and the underlying security must have at least 300 million shares 
currently outstanding.
    \15\ The market capitalization was determined by multiplying a 
settlement price of ($54.02) by the number of shares outstanding 
(866,040,000). This figure was acquired as of November 25, 2024. See 
<a href="https://www.ishares.com/us/products/333011/ishares-bitcoin-trust-etf">https://www.ishares.com/us/products/333011/ishares-bitcoin-trust-etf</a>.
    \16\ See <a href="https://www.coingecko.com/en/coins/bitcoin">https://www.coingecko.com/en/coins/bitcoin</a>.
    \17\ See Amendment No. 2 to Proposed Rule Change to modify the 
position and exercise limits for IBIT options to the applicable 
position and exercise limits as determined by Options 9, Sections 13 
and 15 (SR-ISE-2024-62), filed Mar. 26, 2025, available at <a href="https://www.sec.gov/comments/srise-2024-62/srise202462-593575-1721782.pdf">https://www.sec.gov/comments/srise-2024-62/srise202462-593575-1721782.pdf</a>. 
(``Amendment No. 2'').
    \18\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \19\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/866,040,000 shares 
outstanding).
---------------------------------------------------------------------------

    Position limits, and exercise limits, are designed to limit the 
number of options contracts traded on the exchange in an underlying 
security that an investor, acting alone or in concert with others 
directly or indirectly, may control. These limits, which are described 
in Exchange Rules 307 and 309, are intended to address potential 
manipulative schemes and adverse market impacts surrounding the use of 
options, such as disrupting the market in the security underlying the 
options. Position and exercise limits must balance concerns regarding 
mitigating potential manipulation and the cost of inhibiting potential 
hedging activity that could be used for legitimate economic purposes.
    To achieve this balance, the Exchange proposes to remove IBIT from 
the table of position limits in Interpretation and Policy .01 to 
Exchange Rule 307 as well as the table of exercise limits in 
Interpretation and Policy .01 to Exchange Rule 309 so that options on 
IBIT may trade similar to all other options for which the Exchange has 
not filed to otherwise increase the position limits to levels outside 
of the limits of Exchange Rule 307(d). As a result of removing IBIT 
from the aforementioned tables, it would increase the position and 
exercise limits for options on IBIT from 25,000 to 250,000 contracts 
based on the parameters of Exchange Rule 307(d). By removing IBIT from 
the aforementioned tables, IBIT would be subject to subsequent six (6) 
month reviews to determine future position and exercise limits similar 
to all other options subject to Exchange Rules 307 and 309.
    In addition to IBIT's Exchange Rule 307(d) eligibility for 250,000 
contracts, the Exchange performed additional analysis relying on data 
presented in Amendment No. 2, with respect to IBIT. First, in Amendment 
No. 2, ISE considered IBIT's market capitalization and ADV, and 
prospective position limit in relation to other securities. In 
measuring IBIT against other securities, ISE aggregated market 
capitalization and volume data for securities that have defined 
position limits utilizing data from The Options Clearing Corporations 
(``OCC'').\20\ This pool of data took into consideration 3,897 options 
on single stock securities, excluding broad based ETFs.\21\ Next, ISE 
aggregated the data based on market capitalization and ADV and grouped 
option symbols by position limit utilizing statistical thresholds for 
ADV, based on ninety days, and market capitalization that were one 
standard deviation above the mean for each position limit category 
(i.e. 25,000, 50,000 to 65,000, 75,000, 100,000 to less than 250,000, 
and 250,000).\22\ Exchange Rule 307(d) sets out position limits for 
various contracts. For example, on ISE like on the Exchange, a 25,000 
contract limit applies to those options having an underlying security 
that does not meet the requirements for a higher options contract 
limit. ISE performed an exercise to demonstrate IBIT's position limit 
relative to other options symbols in terms of market capitalization and 
ADV. For reference the market capitalization for IBIT was 
$46,783,480,800 \23\ with an ADV, for the preceding three months prior 
to November 25, 2024, of 39,421,877 shares.\24\
---------------------------------------------------------------------------

    \20\ The computations are based on OCC data from November 25, 
2024. Data displaying zero values in market capitalization or ADV 
were removed.
    \21\ IBIT has one asset and therefore is not comparable to a 
broad based ETF where there are typically multiple components.
    \22\ Exchange Rule 307 sets out position limits for various 
contracts. For example, a 25,000 contract limit applies to those 
options having an underlying security that does not meet the 
requirements for a higher options contract limit. The Exchange notes 
that position limits may also be higher due to corporate actions in 
the underlying equities, such as a stock split. See <a href="https://www.theocc.com/market-data/market-data-reports/series-and-tradingdata/position-limits">https://www.theocc.com/market-data/market-data-reports/series-and-tradingdata/position-limits</a>. As a result, the Exchange's pool of 
data considered higher position limits than 250,000 contracts, where 
applicable.
    \23\ The market capitalization was determined by multiplying a 
settlement price of ($54.02) by the number of shares outstanding 
(866,040,000). This figure was acquired as of November 25, 2024. See 
<a href="https://www.ishares.com/us/products/333011/ishares-bitcoin-trust-etf">https://www.ishares.com/us/products/333011/ishares-bitcoin-trust-etf</a>.

    Based on the above table, as presented in Amendment No. 2,\25\ if 
IBIT were compared to the 1,934 stocks that have position limits of 
250,000 contracts to less than 500,000 contracts it would rank in the 
88th percentile for market capitalization and the 99th percentile for 
ADV.
---------------------------------------------------------------------------

    \25\ See Amendment No. 2 at 9.
---------------------------------------------------------------------------

    ISE, in Amendment No. 2, also analyzed the position limits for IBIT 
by regressing the market capitalization figures and 90-day ADV of all 
non-ETF equities, against their respective position limit figures.\26\ 
From this regression, ISE was able to determine

[[Page 38524]]

the implied coefficients to create a formulaic method for determining 
an appropriate position limit.\27\ In this case, the modeled position 
limit is 565,796 contracts.\28\ The results of ISE's study are below.
---------------------------------------------------------------------------

    \26\ Id.
    \27\ ISE utilized Excel's Data Analysis Package to model the 
position limit.
    \28\ ISE utilized this formula to arrive at the number of 
contracts: ((46,783,380,800 mkt cap * 0.0000002630 market cap 
coefficient) + (39,421,877 ADV * 0.0140402219 ADV coefficient)).

    Based on the aforementioned analysis, as performed by ISE in 
Amendment No. 2, the Exchange believes that the proposed 250,000 
contracts for position and exercise limits is appropriate.
    Second, ISE reviewed IBIT's data relative to the market 
capitalization of the entire bitcoin market in terms of exercise risk 
and availability of deliverables. As of November 25, 2024, there are 
19,787,762 bitcoins in circulation.\29\ At a price of $94,830,\30\ that 
equates to a market capitalization of greater than $1.876 trillion US. 
If a position limit of 250,000 contracts were considered, the 
exercisable risk would represent 2.89% \31\ of the outstanding shares 
outstanding of IBIT. Since IBIT has a creation and redemption process 
managed through the issuer, additionally it can be compared the 
position limit sought to the total market capitalization of the entire 
bitcoin market and in that case, the exercisable risk for options on 
IBIT would be less than 0.072% of all bitcoin outstanding. Assuming a 
scenario where all options on IBIT shares were exercised given the 
proposed 250,000 per same side position and exercise limits, this would 
have a virtually unnoticed impact on the entire bitcoin market. This 
analysis demonstrates that the proposed 250,000 per same side position 
and exercise limits are appropriate for options on IBIT given its 
liquidity.
---------------------------------------------------------------------------

    \29\ See <a href="https://www.coingecko.com/en/coins/bitcoin">https://www.coingecko.com/en/coins/bitcoin</a>.
    \30\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \31\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/866,040,000 shares 
outstanding).
---------------------------------------------------------------------------

    Third, ISE reviewed the proposed position limit by comparing it to 
position limits for derivative products regulated by the Commodity 
Futures Trading Commission (``CFTC''). While the CFTC, through the 
relevant Designated Contract Markets, only regulates options positions 
based upon delta equivalents (creating a less stringent standard), ISE 
examined equivalent bitcoin futures position limits. In particular, ISE 
looked at the CME bitcoin futures contract \32\ that has a position 
limit of 2,000 futures.\33\ On October 22, 2024, CME bitcoin futures 
settled at $94,945.\34\ On October 22, 2024, IBIT settled at $54.02, 
which would equate to greater than 17,557,898 shares of IBIT if the CME 
notional position limit was utilized. Since substantial portions of any 
distributed options portfolio are likely to be out of the money on 
expiration, an options position limit equivalent to the CME position 
limit for bitcoin futures (considering that all options deltas are 
<=1.00) should be a bit higher than the CME implied 175,578 limit.Of 
note, unlike options contracts, CME position limits are calculated on a 
net futures equivalent basis by contract and include contracts that 
aggregate into one or more base contracts according to an aggregation 
ratio(s).\35\ Therefore, if a portfolio includes positions in options 
on futures, CME would aggregate those positions into the underlying 
futures contracts in accordance with a table published by CME on a 
delta equivalent value for the relevant spot month, subsequent spot 
month, single month and all month position limits.\36\ If a position 
exceeds position limits because of an option assignment, CME permits 
market participants to liquidate the excess position within one 
business day without being considered in violation of its rules. 
Additionally, if at the close of trading, a position that includes 
options exceeds position limits for futures contracts, when evaluated 
using the delta factors as of that day's close of trading, but does not 
exceed the limits when evaluated using the previous day's delta 
factors, then the position shall not constitute a position limit 
violation. Based on the aforementioned analysis, the Exchange believes 
that the proposed 250,000 contracts for position and exercise limits is 
appropriate.
---------------------------------------------------------------------------

    \32\ CME Bitcoin Futures are described in Chapter 350 of CME's 
Rulebook.
    \33\ See the Position Accountability and Reportable Level Table 
in the Interpretations & Special Notices Section of Chapter 5 of 
CME's Rulebook.
    \34\ 2,000 futures at a 5 bitcoin multiplier (per the contract 
specifications) equates to $949,450,000 (2000 contracts * 5 BTC per 
contract * $94,945 price of November BTC future) of notional value.

    Fourth, ISE analyzed a position and exercise limit of 250,000 for 
IBIT options against other options on ETFs with an underling commodity, 
namely SPDR Gold Shares (``GLD'') ETF, iShares Silver Trust (``SLV'') 
ETF, and ProShares Bitcoin ETF (``BITO'').\37\ GLD has a float of 306.1 
million shares \38\ and a position limit of 250,000 contract. SLV has a 
float of 520.7 million shares,\39\ and a position limit of 250,000 
contracts. Finally, BITO has 107.65 million shares outstanding \40\ and 
a position limit of

[[Page 38525]]

250,000 contracts. As previously noted, position and exercise limits 
are designed to limit the number of options contracts traded on the 
exchange in an underlying security that an investor, acting alone or in 
concert with others directly or indirectly, may control. A position 
limit exercise in GLD would represent 8.17% of the float of GLD; a 
position limit exercise in SLV would represent 4.8% of the float of 
SLV, and a position limit exercise of BITO would represent 23.22% of 
the float of BITO. In comparison, a 250,000 contract position limit in 
IBIT would represent 2.89% of the float of IBIT. Consequently, the 
250,000 proposed IBIT options position and exercise limit is more 
conservative than the standard applied to GLD, SLV and BITO, and 
appropriate. Additionally, the Exchange notes that the Cboe Bitcoin 
U.S. ETF Index Options (CBTX) and the Cboe Mini Bitcoin U.S. ETF Index 
Options (MBTX),\41\ which trade exclusively on Cboe, are comprised of 
multiple bitcoin ETFs of which IBIT is the highest weighted (at 20%) in 
the index composition.\42\ These indices currently trade pursuant to a 
24,000 contract position and exercise limit.\43\
---------------------------------------------------------------------------

    \37\ GLD, SLV and BITO each hold one asset in trust similar to 
IBIT.
    \38\ See <a href="https://www.ssga.com/us/en/intermediary/etfs/spdr-gold-shares-gld">https://www.ssga.com/us/en/intermediary/etfs/spdr-gold-shares-gld</a>.

that CBTX and MBTX are permitted to trade FLEX as compared to spot 
bitcoin ETF options. See <a href="https://cdn.cboe.com/resources/membership/Cboe_Bitcoin_US_ETF_Options_Comparative_Over">https://cdn.cboe.com/resources/membership/Cboe_Bitcoin_US_ETF_Options_Comparative_Over</a>

5Q99 WB9X71*MTczNDU1NjU5MC4xLjAuMTczNDU1NjU5MC4wLjAuMA.
    \43\ See Cboe Rule 8.32(a). The Exchange notes that given the 
multiplier and notional value of CBTX, the index has a position and 
exercise limit that equates to 1,000,000 contracts of in kind 
exposure to IBIT, which is more than 40 times greater than the 
exposure for options on IBIT at the current 25,000 contract position 
and exercise limit.
---------------------------------------------------------------------------

    Fifth, the Exchange and ISE note that IBIT began trading in penny 
increments as of January 2, 2025 pursuant to the Penny Interval 
Program.\44\ The Commission noted that evidence contained in both the 
Exchanges' Report and the Cornerstone analysis demonstrates that the 
Penny Pilot has benefitted investors and other market participants in 
the form of narrower spreads.\45\ The most actively traded options 
classes are included in the Penny Program based on certain objective 
criteria (trading volume thresholds and initial price tests). As noted 
in the Penny Approval Order, the Penny Program reflects a certain level 
of trading interest (either because the class is newly listed or a 
class that experience a significant growth in investor interest) to 
quote in finer trading increments, which in turn should benefit market 
participants by reducing the cost of trading such options.\46\ IBIT 
options are among a select group of products that have achieved a 
certain level of liquidity that have garnered it the ability to trade 
in finer increments. Failing to increase position and exercise limits 
for IBIT options, now that it is trading in finer increments, may 
artificially inhibit liquidity and create price inefficiency.
---------------------------------------------------------------------------

    \44\ The Exchange may add to the Penny Program a newly listed 
option class provided that (i) it is among the 300 most actively 
traded multiply listed option classes, as ranked by National Cleared 
Volume at OCC, in its first full calendar month of trading and (ii) 
the underlying security is priced below $200 or the underlying index 
is at an index level below $200. Any option class added under this 
provision will be added on the first trading day of the month after 
it qualifies and will remain in the Penny Program for one full 
calendar year, after which it will be subject to the Annual Review 
described in Exchange Rule 501(c)(2). The Exchange may add any 
option class to the Penny Program, provided that (i) it is among the 
75 most actively traded multiply listed option classes, as ranked by 
National Cleared Volume at OCC, in the past six full calendar months 
of trading and (ii) the underlying security is priced below $200 or 
the underlying index is at an index level below $200. Any option 
class added under this provision will be added on the first trading 
day of the second full month after it qualifies and will remain in 
the Penny Program for the rest of the calendar year, after which it 
will be subject to the Annual Review as described in Exchange Rule 
501(c)(2). See Exchange Rule 501(c)(2).
    \45\ See Securities Exchange Act Release No. 88532 (April 1, 
2020), 67 FR 19545, 19548 (April 7, 2020) (File No. 4-443) (Joint 
Industry Plan; Order Approving Amendment No. 5 to the Plan for the 
Purpose of Developing and Implementing Procedures Designed To 
Facilitate the Listing and Trading of Standardized Options To Adopt 
a Penny Interval Program) (``Penny Approval Order'').
    \46\ Id. at 19548.
---------------------------------------------------------------------------

    The Exchange believes that IBIT options has demonstrated that it 
has more than sufficient liquidity to garner an increased position and 
exercise limit of 250,000 contracts. The Exchange believes that any 
concerns related to manipulation and protection of investors are 
mollified by the significant liquidity provision in IBIT. The Exchange 
states that, as a general principle, increases in active trading volume 
and deep liquidity of the underlying securities do not lead to 
manipulation and/or disruption.
    The Exchange believes that increasing the position (and exercise) 
limits for IBIT options would lead to a more liquid and competitive 
market environment for IBIT options, which will benefit customers that 
trade these options. Further, the reporting requirement for such 
options would remain unchanged. Thus, the Exchange will still require 
that each member organization that maintains positions in impacted 
options on the same side of the market, for its own account or for the 
account of a customer, report certain information to the Exchange. This 
information includes, but would not be limited to, the options' 
positions, whether such positions are hedged and, if so, a description 
of the hedge(s). Market-Makers \47\ would continue to be exempt from 
this reporting requirement, however, the Exchange may access Market-
Maker position information.\48\ Moreover, the Exchange's requirement 
that member organizations file reports with the Exchange for any 
customer who held aggregate large long or short positions on the same 
side of the market of 200 or more option contracts of any single class 
for the previous day will remain at this level and will continue to 
serve as an important part of the Exchange's surveillance efforts.\49\
---------------------------------------------------------------------------

    \47\ Market Makers refers to ``Lead Market Makers,'' ``Primary 
Lead Market Makers,'' and ``Registered Market Makers'' collectively. 
See Exchanged Rule 100.
    \48\ The Options Clearing Corporation (``OCC'') through the 
Large option Position Reporting (``LOPR'') system acts as a 
centralized service provider for Member compliance with position 
reporting requirements by collecting data from each Member or Member 
organization, consolidating the information, and ultimately 
providing detailed listings of each Member's report to the Exchange, 
as well as Financial Industry Regulatory Authority, Inc. 
(``FINRA''), acting as its agent pursuant to a regulatory services 
agreement (``RSA''). Member means an individual or organization 
approved to exercise the trading rights associated with a Trading 
Permit. Members are deemed ``members'' under the Exchange Act. See 
Exchanged Rule 100.
    \49\ See Exchanged Rule 310.
---------------------------------------------------------------------------

    The Exchange also has no reason to believe that the growth in 
trading volume in IBIT will not continue. Rather, the Exchange expects 
continued options volume growth in IBIT as opportunities for investors 
to participate in the options markets increase and evolve. The Exchange 
believes that the current position and exercise limits in IBIT options 
are restrictive and will hamper the listed options markets from being 
able to compete fairly and effectively with the over-the-counter 
(``OTC'') markets. OTC transactions occur through bilateral agreements, 
the terms of which are not publicly disclosed to the marketplace. As 
such, OTC transactions do not contribute to the price discovery process 
on a public exchange or other lit markets. The Exchange believes that 
without the proposed changes to position and exercise limits for IBIT 
options, market participants will find the 25,000 contract position 
limit an impediment to their business and investment objectives as well 
as an impediment to efficient pricing. As such, market participants may 
find the less

[[Page 38526]]

transparent OTC markets a more attractive alternative to achieve their 
investment and hedging objectives, leading to a retreat from the listed 
options markets, where trades are subject to reporting requirements and 
daily surveillance. However, the Exchange notes that IBIT's position 
limits would be reviewed on a six month basis, pursuant to Exchange 
Rule 307(d), similar to other options.
    The Exchange represents that the same surveillance procedures 
applicable to all other options on other ETFs currently listed and 
traded on the Exchange will apply to options on the Trust. Also the 
Exchange represents that it has the necessary systems capacity to 
support the new option series. The Exchange believes that its existing 
surveillance and reporting safeguards are designed to deter and detect 
possible manipulative behavior which might potentially arise from 
listing and trading options on ETFs, including the proposed Trust 
options.
    The Exchange believes that the existing surveillance procedures and 
reporting requirements at the Exchange are capable of properly 
identifying disruptive and/or manipulative trading activity. The 
Exchange also represents that it has adequate surveillances in place to 
detect potential manipulation, as well as reviews in place to identify 
continued compliance with the Exchange's listing standards. These 
procedures monitor market activity via automated surveillance 
techniques to identify unusual activity in both options and the 
underlyings, as applicable. The Exchange also notes that large stock 
holdings must be disclosed to the Commission by way of Schedules 13D or 
13G,\50\ which are used to report ownership of stock which exceeds 5% 
of a company's total stock issue and may assist in providing 
information in monitoring for any potential manipulative schemes. 
Further, the Exchange believes that the current financial requirements 
imposed by the Exchange and by the Commission adequately address 
concerns regarding potentially large, unhedged positions in equity 
options. Current margin and risk-based haircut methodologies serve to 
limit the size of positions maintained by any one account by increasing 
the margin and/or capital that a member organization must maintain for 
a large position held by itself or by its customer.\51\ In addition, 
Rule 15c3-1 \52\ imposes a capital charge on member organizations to 
the extent of any margin deficiency resulting from the higher margin 
requirement.

2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Act and the rules and regulations thereunder applicable to the 
Exchange and, in particular, the requirements of Section 6(b) of the 
Act.\53\ Specifically, the Exchange believes the proposed rule change 
is consistent with the Section 6(b)(5) \54\ requirements that the rules 
of an exchange be designed to prevent fraudulent and manipulative acts 
and practices, to promote just and equitable principles of trade, to 
foster cooperation and coordination with persons engaged in regulating, 
clearing, settling, processing information with respect to, and 
facilitating transactions in securities, to remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system, and, in general, to protect investors and the public interest. 
Additionally, the Exchange believes the proposed rule change is 
consistent with the Section (6)(b)(5) \55\ requirement that the rules 
of an exchange not be designed to permit unfair discrimination between 
customers, issuers, brokers, or dealers.

    The Exchange believes that removing IBIT from the table of position 
limits in Interpretation and Policy .01 to Exchange Rule 307 and the 
table of exercise limits in Interpretation and Policy .01 to Exchange 
Rule 309, so its position limit would be reviewed similar to all other 
options for which the Exchange has not filed to otherwise establish the 
position limits to levels outside of the position limits of Exchange 
Rule 307(d) is consistent with the Act. This proposal will remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system, and, in general, protect investors and the 
public interest, because it will provide market participants with the 
ability to more effectively execute their trading and hedging 
activities. Also, based on current trading volume, the resulting 
increase in the position (and exercise) limits for IBIT options may 
allow Market-Makers to maintain their liquidity in these options in 
amounts commensurate with the continued high consumer demand in IBIT 
options. Subjecting options on IBIT to the position limits in Exchange 
Rule 307(d) and corresponding exercise limits in Exchange Rule 309 may 
also encourage other liquidity providers to continue to trade on the 
Exchange rather than shift their volume to OTC markets, which will 
enhance the process of price discovery conducted on the Exchange 
through increased order flow. Further, this proposed change would allow 
institutional investors to utilize IBIT options for prudent risk 
management purposes. The Exchange notes that IBIT's position limits 
would be reviewed on a six month basis, pursuant to Exchange Rule 
307(d), similar to other options.
    In addition, the Exchange believes that the current liquidity in 
IBIT will mitigate concerns regarding potential manipulation of IBIT 
options and/or disruption of IBIT upon amending the table of position 
limits in Interpretation and Policy .01 to Exchange Rule 307 and the 
table of exercise limits in Interpretation and Policy .01 to Exchange 
Rule 309.
    Additionally, the regression model performed by ISE demonstrates 
that the proposed position limit is half of the modeled limit given the 
liquidity of IBIT. Comparing IBIT's data relative to the market 
capitalization of the entire bitcoin market in terms of exercise risk 
and availability of deliverables, the Exchange was able to conclude 
that if a position limit of 250,000 contracts were considered, the 
exercisable risk would represent 2.89% \56\ of the shares outstanding 
of IBIT. Since IBIT has a creation and redemption process managed 
through the issuer (whereby Bitcoin is used to create IBIT shares), the 
position limit can be compared to the total market capitalization of 
the entire bitcoin market and in that case, the exercisable risk for 
options on IBIT would represent less than .072% of all bitcoin 
outstanding.\57\ Comparing the proposed position limit to position 
limits for equivalent bitcoin futures position limits, the analysis 
demonstrated that a 250,000 contracts position and exercise limits 
would be appropriate.
---------------------------------------------------------------------------

    \56\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/866,040,000 shares 
outstanding).
    \57\ This number was arrived at with this calculation: ((250,000 
limit * 100 shares per option * $54.02 settle)/(19,787,762 BTC 
outstanding * $94,830 BTC price)).
---------------------------------------------------------------------------

    Comparing a position limit of 250,000 for IBIT options against 
other options on ETFs with an underling commodity, namely GLD, SLV and 
BITO, a position limit exercise in GLD represents 8.17% of the float of 
GLD, a position limit exercise in SLV represents 4.8% of the float of 
SLV, and a position limit exercise of BITO represents 23.22% of the 
float of BITO. In comparison, a 250,000 contract position limit in IBIT

[[Page 38527]]

options would represent 2.89% of the float of IBIT. Consequently, a 
250,000 IBIT options position limit is more conservative than the 
standard applied to GLD, SLV and BITO, and appropriate. Also, the 
Exchange notes that Cboe's proprietary CBTX and MBTX indices weight 
IBIT the highest (at 20%) in its index composition among the other ETFs 
that comprise the index.\58\ The Exchange notes that today, these 
indexes have a position of 24,000 contracts which is much higher than 
the current position limits for IBIT options when considering the 
notional value of the indices.\59\ These indexes are already trading 
with position and exercise limits that are higher than the lowest 
position limit for an industry index option.\60\
---------------------------------------------------------------------------

    \58\ See <a href="https://www.cboe.com/tradable_products/bitcoin-etf-indexoptions">https://www.cboe.com/tradable_products/bitcoin-etf-indexoptions</a>?utm_source=mcae&utm_medium=email&utm_campaign=bitcoin_ef
t_options_launch.
    \59\ See Cboe Rule 8.32(a). The Exchange notes that given the 
multiplier and notional value of CBTX, the index has a position and 
exercise limit that equates to 1,000,000 contracts of in kind 
exposure to IBIT, which is more than 40 times greater than the 
exposure for options on IBIT at the current 25,000 contract position 
and exercise limit.
    \60\ 18,000 contracts is the lowest position limit for industry 
index options if the Exchange determines, at the time of a review 
conducted pursuant to subparagraph (2) of this paragraph (a), that 
any single underlying stock accounted, on average, for thirty 
percent (30%) or more of the index value during the thirty (30)-day 
period immediately preceding the review. See Exchange Rule 1805. 
Further, Cboe Rule 8.32(a)(3) permits a limit of 31,500 contracts if 
the Exchange determines that the conditions specified in Rule 
8.32(a)(1) and (2), which would require the establishment of a lower 
limit, have not occurred.
---------------------------------------------------------------------------

    The Exchange notes that IBIT began trading in penny increments as 
of January 2, 2025 pursuant to the Penny Interval Program.\61\ The 
Commission noted that evidence contained in both the Exchanges' Report 
and the Cornerstone analysis demonstrates that the Penny Pilot has 
benefitted investors and other market participants in the form of

included in the Penny Program based on certain objective criteria

Penny Approval Order, the Penny Program reflects a certain level of 
trading interest (either because the class is newly listed or a class

finer trading increments, which in turn should benefit market 
participants by reducing the cost of trading such options.\63\ IBIT 
options are among a select group of products that have achieved a 
certain level of liquidity that have garnered it the ability to trade 
in finer increments pursuant to the Penny Interval Program. Failing to 
permit IBIT options to potentially increase position and exercise 
limits given the trading in finer increments, may artificially inhibit 
liquidity and create price inefficiency for IBIT options.
---------------------------------------------------------------------------

    \61\ The Exchange may add to the Penny Program a newly listed 
option class provided that (i) it is among the 300 most actively 
traded multiply listed option classes, as ranked by National Cleared 
Volume at OCC, in its first full calendar month of trading and (ii) 
the underlying security is priced below $200 or the underlying index 
is at an index level below $200. Any option class added under this 
provision will be added on the first trading day of the month after

    Finally, as discussed above, the Exchange's surveillance and 
reporting safeguards continue to be designed to deter and detect 
possible manipulative behavior that might arise from increasing or 
eliminating position and exercise limits in certain classes. The 
Exchange believes that the current financial requirements imposed by 
the Exchange and by the Commission adequately address concerns 
regarding potentially large, unhedged positions in the options on the 
underlying securities, further promoting just and equitable principles 
of trading, the maintenance of a fair and orderly market, and the 
protection of investors.

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. In this regard and as 
indicated above, the Exchange notes that the rule change is being 
proposed as a competitive response to filings submitted by ISE.\64\
---------------------------------------------------------------------------

    \64\ See supra note 4.
---------------------------------------------------------------------------

    The Exchange's proposal does not burden intra-market competition 
because all Members would be subject to the position limits in Exchange 
Rule 307(d) and corresponding exercise limits in Exchange Rule 309. The 
Exchange believes that the proposed rule change will also provide 
additional opportunities for market participants to continue to 
efficiently achieve their investment and trading objectives for equity 
options on the Exchange.
    The Exchange does not believe that the proposed rule change will 
impose any burden on inter-market competition as the proposal is not 
competitive in nature. The Exchange expects that all option exchanges 
will adopt substantively similar proposals, such that the Exchange's 
proposal would benefit competition. For these reasons, the Exchange 
does not believe that the proposed rule change will impose any burden 
on competition not necessary or appropriate in furtherance of the 
purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    The Exchange has filed the proposed rule change pursuant to Section 
19(b)(3)(A)(iii) of the Act \65\ and Rule 19b-4(f)(6) thereunder.\66\ 
Because the foregoing proposed rule change does not: (i) significantly 
affect the protection of investors or the public interest; (ii) impose 
any significant burden on competition; and (iii) become operative for 
30 days from the date on which it was filed, or such shorter time as 
the Commission may designate, it has become effective pursuant to 
Section 19(b)(3)(A)(iii) of the Act \67\ and subparagraph (f)(6) of 
Rule 19b-4 thereunder.\68\
---------------------------------------------------------------------------

    \65\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \66\ 17 CFR 240.19b-4(f)(6).
    \67\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \68\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied the pre-filing requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \69\ under the 
Act does not normally become operative prior to 30 days after the date 
of the filing. However, pursuant to Rule 19b-4(f)(6)(iii),\70\ the 
Commission may

[[Page 38528]]

designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange has 
requested that the Commission waive the 30-day operative delay so that 
the proposal may become operative immediately upon filing. The 
Commission previously approved the proposed increase to the position 
and exercise limits for iShares Bitcoin Trust ETF.\71\ The Exchange 
represents that the same surveillance procedures applicable to the 
Exchange's other options products listed and traded on the Exchange 
will apply to options on the Trust, and that its existing surveillance 
and reporting safeguards are designed to deter and detect possible 
manipulative behavior which might potentially arise from listing and 
trading options on ETFs, including the proposed Trust options. The 
Commission believes that waiver of the operative delay could benefit 
investors by providing an additional venue for trading iShares Bitcoin 
Trust ETF options without the prior position and exercise limits. 
Therefore, the Commission believes that waiver of the 30-day operative 
delay is consistent with the protection of investors and the public 
interest. Accordingly, the Commission hereby waives the 30-day 
operative delay and designates the proposed rule change as operative 
upon filing.\72\

Modified by Amendment Nos. 2 and 3, Regarding Position and Exercise 
Limits for Options on the iShares Bitcoin Trust ETF) (SR-ISE-2024-
62).
    \72\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission shall institute proceedings to 
determine whether the proposed rule should be approved or disapproved.
