SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-103748; File No. SR-BOX-2025-23]


Self-Regulatory Organizations; BOX Exchange LLC; Notice of Filing 
and Immediate Effectiveness of Proposed Change To Amend BOX Rule 3120 
To Increase the Position and Exercise Limits for the Grayscale Bitcoin 
Mini Trust ETF, the Bitwise Bitcoin ETF, and the Grayscale Bitcoin 
Trust ETF

August 20, 2025.
    Pursuant to Section 19(b)(1) \1\ of the Securities Exchange Act of 
1934 (``Act'') \2\ and Rule 19b-4 thereunder,\3\ notice is hereby given 
that, on August 15, 2025, BOX Exchange LLC (``BOX'' or the 
``Exchange'') filed with the Securities and Exchange Commission (the 
``Commission'') the proposed rule change as described in Items I and II 
below, which Items have been prepared by the self-regulatory 
organization. The Commission is publishing this notice to solicit 
comments on the proposed rule change from interested persons.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 78s(b)(1).
    \2\ 15 U.S.C. 78a.
    \3\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    The Exchange proposes to amend BOX Rule 3120 (Position Limits) to 
increase the position and exercise limits for the Grayscale Bitcoin 
Mini Trust ETF (``BTC''), the Bitwise Bitcoin ETF (``BITB'') and the 
Grayscale Bitcoin Trust ETF (``GBTC''). The text of the proposed rule 
change is available from the principal office of the Exchange, at the 
Commission's Public Reference Room and also on the Exchange's internet 
website at <a href="https://rules.boxexchange.com/rulefilings">https://rules.boxexchange.com/rulefilings</a>.

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 self-regulatory organization 
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 parts of such statements.

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

1. Purpose
    The Exchange proposes to amend Rule 3120, Position Limits,\4\ to 
permit BTC, BITB, and GBTC to increase their position and exercise 
limits for options on BTC, BITB, and GBTC from 25,000 contracts by 
removing BTC, BITB, and GBTC from IM-3120-2. This is a competitive 
filing based on similar proposals submitted by NYSE Arca, Inc. 
(``Arca'') and approved by the Securities and Exchange Commission 
(``Commission'').\5\
---------------------------------------------------------------------------

    \4\ The Exchange notes that Rule 3140(c) Exercise Limits 
provides that limits shall be determined in the manner described in 
Rule 3120 (Position Limits). Additionally, IM-3140-1 provides the 
exercise limits established under Rule 3140, in respect to options 
on shares or other securities that represent interests in registered 
investment companies (or series thereof) organized as open-end 
management investment companies, unit investment trusts or similar 
entities that satisfy the criteria set forth in Rule 5020 shall be 
equivalent to the position limits prescribed for such options in IM-
3120-2, subject to any exemptions granted in respect to such 
position limits.
    \5\ See Securities Exchange Act Release Nos. 103568 (July 29, 
2025), 90 FR 36238 (August 1, 2025), (SR-NYSEArca-2025-10) (Order 
Approving a Proposed Rule Change, as Modified by Amendment No. 2, To 
Amend Rules Regarding Position and Exercise Limits for Options on 
the Grayscale Bitcoin Mini Trust (''BTC'') and the Bitwise Bitcoin 
ETF (``BITB'') and To Permit Flexible Exchange Options on BTC and 
BITB) and 103567 (July 29, 2025), 90 FR 36253 (August 1, 2025) (SR-
NYSEArca-2025-07) (Order Approving a Proposed Rule Change, as 
Modified by Amendment No. 3, To Amend Rules Regarding Position and 
Exercise Limits for Options on the Grayscale Bitcoin Trust 
(``GBTC'') and To Permit Flexible Exchange Options on GBTC.
---------------------------------------------------------------------------

BTC and BITB
    On October 18, 2024, the Commission approved the listing and 
trading of BTC and BITB on NYSE American LLC (``NYSE American'').\6\ On 
November 22, 2024, Arca obtained rule authority to trade options on BTC 
and BITB.\7\ The current position and exercise limits for BTC and BITB 
options are 25,000 contracts on BOX, the lowest limit available in 
options.\8\ Arca proposed to effectively increase the aggregated 
position and exercise limits for each ETF to 250,000 contracts.\9\ Arca 
noted that BTC and BITB currently qualify for this increased limit 
pursuant to Arca Rule 6.8-O Commentary .06(e), which requires that, for 
the most recent six-month period, trading volume for the underlying 
security is at least 100,000,000 shares.\10\ Arca noted that, as of 
November 25, 2024, during the most recent six-month period, trading 
volume for BTC was 163,712,700 shares. Arca noted that during the same 
period, trading volume for BITB was 288,800,860 shares. In addition, 
Arca noted that, as of November 25, 2024, the market capitalization for 
BTC was $3,496,748,882 \11\ with an average daily volume (``ADV'') for 
the preceding three months of 2,036,369 shares, and the market 
capitalization of BITB was 4,095,157,000 \12\ with an ADV for the three 
prior months of 2,480,478. BTC and BITB are well above the requisite 
minimum of 100,000,000 shares necessary to qualify for the 250,000 
contract position and exercise limit. Also, Arca noted that, as of 
November 25, 2024, there were 19,787,762 bitcoins in circulation.\13\ 
At a price of $94,830 per bitcoin,\14\ that equates to a market 
capitalization of greater than $1.876 trillion. Arca noted that if a 
position limit of 250,000 contracts were considered for each ETF, the 
exercisable risk would represent 30.14% \15\ of BTC

[[Page 41421]]

shares outstanding; and 31.27%\16\ of BITB shares outstanding. Given 
the liquidity of BTC and BITB, the current 25,000 position limit 
appears extremely conservative.
---------------------------------------------------------------------------

    \6\ See Securities Exchange Act Release No. 101386 (October 18, 
2024), 89 FR 84960 (October 24, 2024) (SR-NYSEAMER-2024-49) (order 
approving rules to permit the listing and trading of options on BTC 
and BITB, among others) (the ``ETF Options Approval Order'').
    \7\ See Securities Exchange Act Release No. 101713 (November 22, 
2024), 89 FR 94839 (November 29, 2024) (SR-NYSEARCA-2024-101) 
(notice of immediately effective rule change to permit BTC and BITB 
options trading, based on the already-approved NYSE American rules) 
(the ``Arca ETF Options Notice'').
    \8\ See BOX IM-3120-2.
    \9\ See Securities Exchange Act Release No. 103568 (July 29, 
2025), 90 FR 36238 (August 1, 2025), (SR-NYSEArca-2025-10) (Order 
Approving a Proposed Rule Change, as Modified by Amendment No. 2, To 
Amend Rules Regarding Position and Exercise Limits for Options on 
the Grayscale Bitcoin Mini Trust (''BTC'') and the Bitwise Bitcoin 
ETF (``BITB'') and To Permit Flexible Exchange Options on BTC and 
BITB).
    \10\ See Arca Rule 6.8-O Commentary .06(e) (providing at 
subparagraph (e) that the position limit shall be 250,000 contracts 
for options: (i) on underlying stock or Exchange-Traded Fund Share 
that had trading volume of at least 100,000,000 shares during the 
most recent six-month trading period; or (ii) on an underlying stock 
or Exchange-Traded Fund Share that had trading volume of at least 
75,000,000 shares during the most recent six-month trading period 
and has at least 300,000,000 shares currently outstanding).
    \11\ The market capitalization of BTC was determined by 
multiplying a settlement price ($42.16) by the number of shares 
outstanding (82,939,964). Data represents figures from FactSet as of 
November 25, 2024.
    \12\ The market capitalization of BITB was determined by 
multiplying a settlement price ($51.70) by the number of shares 
outstanding (79,950,100). Data represents figures from FactSet as of 
November 25, 2024.
    \13\ See <a href="https://www.coingecko.com/en/coins/bitcoin">https://www.coingecko.com/en/coins/bitcoin</a>.
    \14\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \15\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/82,939,964 BTC shares 
outstanding).
    \16\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/79,950,100 BITB shares 
outstanding).
---------------------------------------------------------------------------

    First, Arca reviewed the ETFs' data relative to the market 
capitalization of the entire bitcoin market in terms of exercise risk 
and availability of deliverables. Arca noted that, as noted above, as 
of November 25, 2024, there were 19,787,762 bitcoins in 
circulation.\17\ At a price of $94,830 per bitcoin,\18\ that equates to 
a market capitalization of greater than $1.876 trillion. Arca noted 
that if the proposed aggregated position limit of 250,000 contracts 
were considered, the exercisable risk would represent 30.14% of BTC 
shares outstanding \19\ and 31.27% of BITB shares outstanding.\20\ Arca 
noted that since each ETF has a creation and redemption process managed 
through the issuer (whereby bitcoin is used to create BTC or BITB 
shares, as applicable), 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 each ETF would represent less than 
0.06% (BTC) or 0.07% (BITB) of all bitcoin outstanding.\21\
---------------------------------------------------------------------------

    \17\ See <a href="https://www.coingecko.com/en/coins/bitcoin">https://www.coingecko.com/en/coins/bitcoin</a>.
    \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/82,939,964 BTC shares 
outstanding).
    \20\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/79,950,100 BITB shares 
outstanding).
    \21\ For BTC, this number was arrived at with this calculation: 
((250,000 limit * 100 shares per option * $42.16 settle)/(19,787,762 
bitcoin outstanding * $94,830 bitcoin price)); and for BITB, this 
number was arrived at with this calculation: ((250,000 limit * 100 
shares per option * $51.70 settle)/(19,787,762 bitcoin outstanding * 
$94,830 bitcoin price)).
---------------------------------------------------------------------------

    Next, Arca reviewed the proposed position limit by comparing it to 
position limits for derivative products regulated by the CFTC. While 
the CFTC, through the relevant Designated Contract Markets, only 
regulates options positions based upon delta equivalents (creating a 
less stringent standard), Arca examined equivalent bitcoin futures 
position limits. In particular, Arca looked to the CME bitcoin futures 
contract \22\ that has a position limit of 2,000 futures. Arca noted 
that, on October 22, 2024, CME bitcoin futures settled at $94,945.\23\ 
Arca noted that, on October 22, 2024, BTC settled at $29.90, and BITB 
settled at $36.74, which would equate to approximately 31,754,181 and 
25,842,406 shares of BTC and BITB, respectively, 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 limit of 317,541 
(BTC) and 258,424 (BITB).
---------------------------------------------------------------------------

    \22\ CME Bitcoin Futures are described in Chapter 350 of CME's 
Rulebook.
    \23\ See the Position Accountability and Reportable Level Table 
in the Interpretations & Special Notices Section of Chapter 5 of 
CME's Rulebook.
---------------------------------------------------------------------------

    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).\24\ 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.\25\ 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. Considering CME's position limits on bitcoin futures, the 
Exchange believes a 250,000-contract limit for options on each ETF 
would be appropriate.
---------------------------------------------------------------------------

    \24\ See <a href="https://www.cmegroup.com/education/courses/market-regulation/position-limits/positionlimits-aggregation-of-contracts-and-table.htm">https://www.cmegroup.com/education/courses/market-regulation/position-limits/positionlimits-aggregation-of-contracts-and-table.htm</a>.
    \25\ See id.
---------------------------------------------------------------------------

    Finally, Arca analyzed a position and exercise limit of 250,000 for 
BTC and BITB against other options on commodity ETFs, namely SPDR Gold 
Shares (``GLD'') and iShares Silver Trust (``SLV'').\26\ GLD has a 
float of 306.1 million shares and a position limit of 250,000 
contracts.\27\ 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. In comparison, a 250,000-
contract position limit in each of BTC and BITB, would represent 30.14% 
of the BTC float and 31.27% of the BITB float. While less conservative 
than the standard applied to options on GLD, the Exchange nonetheless 
believes that subjecting options on BTC and BITB to a 250,000 contract 
position and exercise limit would be appropriate.\28\
---------------------------------------------------------------------------

    \26\ Like BTC and BITB, GLD and SLV each hold one asset in 
trust.
    \27\ 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>.
    \28\ See, e.g., BOX Rule 3120(d)(5) (setting forth trading 
volume requirements to qualify for a 250,000 contract position (and 
exercise) limit).
---------------------------------------------------------------------------

    Based on the foregoing, the Exchange believes that BTC and BITB 
each have more than sufficient liquidity to garner an increased 
position and exercise limit of 250,000 same-side contracts pursuant to 
BOX Rules 3120 and 3140. The Exchange believes that the significant 
liquidity present in each ETF mitigates against the potential for 
manipulation.
    The Exchange believes that allowing options on each ETF to have 
increased aggregated position and exercise limits would lead to a more 
liquid and competitive market environment for such 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 Participant that maintains positions in 
options on BTC or BITB, 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 \29\ would continue to be 
exempt from this reporting requirement, however, the Exchange may 
access Market Maker position information.\30\ Moreover, the Exchange's 
requirement that Participants file reports with the

[[Page 41422]]

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.\31\
---------------------------------------------------------------------------

    \29\ The term ``Market Maker'' means an Options Participant 
registered with the Exchange for the purpose of making markets in 
options contracts traded on the Exchange and that is vested with the 
rights and responsibilities specified in the Rule 8000 Series. All 
Market Makers are designated as specialists on the Exchange for all 
purposes under the Exchange Act or Rules thereunder. See BOX Rule 
100(31).
    \30\ OCC through the Large Option Position Reporting (``LOPR'') 
system acts as a centralized service provider for Participant 
compliance with position reporting requirements by collecting data 
from each Participant, consolidating the information, and ultimately 
providing detailed listings of each Participant's report to the 
Exchange, as well as FINRA, acting as its agent pursuant to a 
regulatory services agreement (``RSA'').
    \31\ See BOX Rule 3150.
---------------------------------------------------------------------------

GBTC
    On October 18, 2024, the Commission approved the listing and 
trading of GBTC options on NYSE American.\32\ On November 22, 2024, 
Arca received rule authority to trade GBTC options with a 25,000 
contract position limit, the lowest limit available in options.\33\ 
Arca noted that GBTC currently qualifies for a 250,000-limit on same-
side contracts pursuant to Arca Rule 6.8-O Commentary .06(e)(i), which 
requires that trading volume for the underlying security in the most 
recent six months be at least 100,000,000 shares.\34\ Arca noted that, 
as of November 25, 2024, during the most recent six-month period, 
trading volume for GBTC was 550,687,400 shares. In addition, Arca noted 
that, as of November 25, 2024, the market capitalization for GBTC was 
$20,661,316,542,\35\ with an average daily volume (``ADV'') for the 
preceding three months of 3,829,597 shares. GBTC is well above the 
requisite minimum of 100,000,000 shares necessary to qualify for the 
250,000-contract position and exercise limit. Also, Arca noted that, as 
of November 25, 2024, there were 19,787,762 bitcoins in 
circulation.\36\ At a price of $94,830 per bitcoin,\37\ that equates to 
a market capitalization of greater than $1.876 trillion. If an 
aggregated position and exercise limit of 250,000 contracts were 
considered, the exercisable risk would represent 9.13%\38\ of GBTC 
shares outstanding. Given GBTC's liquidity, the current 25,000-contract 
position (and exercise) limit is extremely conservative.

or Exchange-Traded Fund Share that had trading volume of at least 
75,000,000 shares during the most recent six-month trading period 
and has at least 300,000,000 shares currently outstanding). 1 See 
Securities Exchange Act Release No. 103567 (July 29, 2025), 90 FR

Proposed Rule Change, as Modified by Amendment No. 3, To Amend Rules 
Regarding Position and Exercise Limits for Options on the Grayscale 
Bitcoin Trust (``GBTC'') and To Permit Flexible Exchange Options on 
GBTC.
    \35\ The market capitalization of GBTC was determined by 
multiplying a settlement price ($75.42) by the number of shares 
outstanding (273,950,100). Data represents figures from FactSet as 
of November 25, 2024.
    \36\ See <a href="https://www.coingecko.com/en/coins/bitcoin">https://www.coingecko.com/en/coins/bitcoin</a>.
    \37\ This is the approximate price of bitcoin from 4:00 p.m. ET

    \38\ This percentage is arrived at with this equation: (250,000

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

    First, Arca reviewed GBTC's data relative to the market 
capitalization of the entire bitcoin market in terms of exercise risk 
and availability of deliverables. As noted above, as of November 25, 
2024, there were 19,787,762 bitcoins in circulation.\39\ At a price of 
$94,830 per bitcoin,\40\ Arca noted that equates to a market 
capitalization of greater than $1.876 trillion. If an aggregated 
position (and exercise) limit of 250,000 contracts were considered, the 
exercisable risk would represent 9.13% \41\ of the outstanding shares 
of GBTC. Since GBTC has a creation and redemption process managed 
through the issuer (whereby bitcoin is used to create GBTC 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 GBTC would represent less than 0.10% of all bitcoin 
outstanding.\42\ The Exchange notes that if GBTC options were subject 
to a 250,000-contract position and exercise limit (based on GBTC 
trading volume) and if all options on GBTC shares were exercised at 
once, this occurrence would have a virtually unnoticed impact on the 
entire bitcoin market. This analysis demonstrates that a 250,000-
contract position (and exercise) limit for GBTC options would be 
appropriate given GBTC's liquidity.

position limits for derivative products regulated by the CFTC. While 
the CFTC, through the relevant Designated Contract Markets, only 
regulates options positions based upon delta equivalents (creating a 
less stringent standard), Arca examined equivalent bitcoin futures 
position limits. In particular, Arca looked to the CME bitcoin futures 
contract,\43\ which has a position limit of 2,000 futures (for the 
initial spot month).\44\ Arca noted that, on October 22, 2024, CME 
bitcoin futures settled at $94,945.\45\ Arca noted that on October 22, 
2024, GBTC settled at $53.64, which would equate to greater than 
17,700,410 shares of GBTC 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 limit of 177,004.
---------------------------------------------------------------------------

    \43\ CME Bitcoin Futures are described in Chapter 350 of CME's 
Rulebook.
    \44\ See the Position Accountability and Reportable Level Table 
in the Interpretations & Special Notices Section of Chapter 5 of 
CME's Rulebook. Each CME bitcoin futures contract is valued at five 
bitcoins as defined by the CME CF Bitcoin Reference Rate (``BRR''). 
See CME Rule 35001.
    \45\ 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.
---------------------------------------------------------------------------

    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).\46\ 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.\47\ 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. Considering CME's position limits on bitcoin futures, the 
Exchange believes a 250,000-contract limit for GBTC options would be 
appropriate.

    Finally, Arca analyzed a position and exercise limit of 250,000 for 
GBTC against options on SPDR Gold Shares (``GLD''), which (like GBTC), 
is a commodity-backed ETF.\48\ Arca noted that GLD has a float of 306.1 
million shares and a position limit of 250,000 contracts.\49\ 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. Arca noted that a position limit 
exercise in GLD would represent 8.17% of the float of GLD. In 
comparison, Arca noted that a 250,000 contract position limit in GBTC 
would represent 9.13% of the float of GBTC. While less conservative 
than the standard applied to options on GLD, Arca nonetheless believes 
that subjecting GBTC options to a 250,000 contract position and 
exercise limit would be appropriate.\50\
---------------------------------------------------------------------------

    \48\ GLD, like GBTC, holds one asset in trust.
    \49\ 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>.
    \50\ See, e.g., Arca Rule 6.8-O, Commentary .06(e) (setting 
forth trading volume requirements to qualify for a 250,000-contract 
position (and exercise) limit).
---------------------------------------------------------------------------

    Based on the foregoing, the Exchange believes that GBTC has more 
than sufficient liquidity to garner an increased position and exercise 
limit of 250,000 same-side contracts. The Exchange believes that the 
significant liquidity present in GBTC mitigates against the potential 
for manipulation.
    The Exchange believes that allowing GBTC options to have increased 
aggregated position and exercise limits would lead to a more liquid and 
competitive market environment for such 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 Participant that maintains positions in GBTC 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 \51\ would continue to be exempt from 
this reporting requirement, however, the Exchange may access Market 
Maker position information.\52\ Moreover, the Exchange's requirement 
that Participants 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.\53\
---------------------------------------------------------------------------

    \51\ The term ``Market Maker'' means an Options Participant 
registered with the Exchange for the purpose of making markets in 
options contracts traded on the Exchange and that is vested with the 
rights and responsibilities specified in the Rule 8000 Series. All 
Market Makers are designated as specialists on the Exchange for all 
purposes under the Exchange Act or Rules thereunder. See BOX Rule 
100(31).
    \52\ OCC through the LOPR system acts as a centralized service 
provider for Participant compliance with position reporting 
requirements by collecting data from each Participant, consolidating 
the information, and ultimately providing detailed listings of each 
Participant's report to the Exchange, as well as FINRA, acting as 
its agent pursuant to a RSA.
    \53\ See BOX Rule 3150.
---------------------------------------------------------------------------

    The Exchange also has no reason to believe that the growth in 
trading volume in BTC, BITB, and GBTC options will not continue. 
Rather, the Exchange expects continued options volume growth in BTC, 
BITB, and GBTC as opportunities for investors to participate in the 
options markets increase and evolve. The Exchange believes that the 
current position and exercise limits in BTC, BITB, and GBTC 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 BTC, 
BITB, and GBTC 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 a result, 
market participants may find the less 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.
    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 to identify unusual activity in both 
options and the underlying equities.
2. Statutory Basis
    The Exchange believes that the proposal is consistent with the 
requirements of Section 6(b) of the Securities Exchange Act of 1934 
(the ``Act''),\54\ in general, and Section 6(b)(5) of the Act,\55\ in 
particular, in that it is 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 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) \56\ requirement that 
the rules of an exchange not be designed to permit unfair 
discrimination between customers, issuers, brokers, or dealers.

BTC and BITB
    The Exchange believes the proposed rule change to remove the 
25,000-contract position (and exercise) limit on BTC and BITB options 
thus allowing such options to qualify for higher aggregated limits 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 as it will provide market participants with the 
ability to more effectively execute their trading and hedging 
activities. In addition, this proposed change may allow Market Makers 
to maintain their liquidity in these options in amounts commensurate 
with the continued demand for BTC and BITB options. Further, an 
increased aggregated position (and exercise) limit on BTC and BITB 
options may 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. The Exchange notes that permitting a 
higher aggregated position (and exercise) limit on BTC and BITB options 
would further allow institutional investors to utilize such options for 
prudent risk management purposes.
    As noted herein, Arca analyzed several data points that support the 
appropriateness of an aggregated

[[Page 41424]]

position (and exercise) limit of 250,000 contracts for BTC and BITB 
options based on recent trading volume in each ETF. Specifically, Arca 
noted that a comparison of each ETF's market capitalization to the 
bitcoin market in terms of exercise risk and availability of 
deliverables revealed that the exercisable risk of an aggregated limit 
of 250,000 contracts represented 30.14% and 31.27% of BTC and BITB 
shares outstanding. Further, since each ETF has a creation and 
redemption process managed through the issuer (whereby bitcoin is used 
to create BTC or BITB shares, as applicable), a 250,000-contract 
position (and exercise) limit as compared to the market capitalization 
of the bitcoin market indicated that the exercisable risk for options 
on each ETF represented less than 0.06% (BTC) or 0.07% (BITB) of all 
bitcoin outstanding as noted by Arca. Moreover, a comparison of a 
250,000-contract position limit for options on each ETF to the (actual) 
position limits for equivalent bitcoin futures revealed that a 250,000-
contract limit for each ETF would be appropriate. Finally, Arca 
compared an aggregated position limit of 250,000 contracts for each ETF 
against GLD, another commodity-backed ETF. A position limit exercise in 
GLD represents 8.17% of the float of GLD. By comparison, Arca noted 
that a position limit exercise in each ETF (assuming a 250,000-contract 
limit would represent 30.14% (BTC) and 31.27% (BITB) of that ETF's 
float. Although a 250,000-contract position (and exercise) limit on BTC 
and BITB options would not be as conservative as the standard applied 
to GLD, it is comparable and therefore appropriate.
GBTC
    The Exchange believes the proposed rule change to remove the 
25,000-contract position (and exercise) limit on GBTC options thus 
allowing such options to qualify for higher aggregated limits 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 as it will provide market participants with the 
ability to more effectively execute their trading and hedging 
activities. In addition, this proposed change may allow Market Makers 
to maintain their liquidity in these options in amounts commensurate 
with the continued demand for GBTC options. Further, an increased 
aggregated position (and exercise) limit on GBTC options may 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. The Exchange notes that permitting a higher aggregated position 
(and exercise) limit on GBTC options would further allow institutional 
investors to utilize such options for prudent risk management purposes.
    As noted herein, Arca analyzed several data points that support the 
appropriateness of an aggregated position (and exercise) limit of 
250,000 contracts for GBTC options based on recent trading volume in 
GBTC. Specifically, Arca noted that a comparison of GBTC's market 
capitalization to the bitcoin market in terms of exercise risk and 
availability of deliverables revealed that the exercisable risk of an 
aggregated limit of 250,000 contracts represented 9.13% of GBTC shares 
outstanding. Further, since GBTC has a creation and redemption process 
managed through the issuer (whereby bitcoin is used to create GBTC 
shares), a 250,000-contract position (and exercise) limit as compared 
to the market capitalization of the bitcoin market indicated that the 
exercisable risk for GBTC options represented less than 0.10% of all 
bitcoin outstanding as noted by Arca. Moreover, a comparison of a 
250,000-contract position limit for GBTC options to the (actual) 
position limits for equivalent bitcoin futures revealed that a 250,000-
contract limit would be appropriate. Finally, Arca compared an 
aggregated position limit of 250,000 contracts for GBTC options against 
GLD, another commodity backed ETF. Arca noted that a position limit 
exercise in GLD represents 8.17% of the float of GLD. By comparison, a 
position limit exercise in GBTC options (assuming a 250,000-contract 
limit) would represent 9.13% of the GBTC float. Although a 250,000-
contract position (and exercise) limit on GBTC options would not be as 
conservative as the standard applied to GLD, it is comparable and 
therefore appropriate.

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

    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 Arca.\57\
---------------------------------------------------------------------------

    \57\ See supra note 4.
---------------------------------------------------------------------------

    The Exchange's proposal does not burden intra-market competition 
because all Participants would be subject to the position limits in 
Rule 3120 and corresponding exercise limits in Rule 3140. 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 intermarket 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

    The Exchange has neither solicited nor received comments on the 
proposed rule change.

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 \58\ and Rule 19b-4(f)(6) thereunder.\59\ 
Because the 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 prior to 
30 days from the date on which it was filed, or such shorter time as 
the Commission may designate, if consistent with the protection of 
investors and the public interest, the proposed rule change has become 
effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-
4(f)(6)(iii) thereunder.
---------------------------------------------------------------------------

    \58\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \59\ 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) \60\ 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),\61\ the 
Commission may

[[Page 41425]]

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 removal of the 25,000 contract 
position and exercise limits for GBTC, BTC, and BITB, such that those 
funds will be subject to the position and exercise limits as determined 
for equity options for which no set limit has been otherwise 
established on that exchange.\62\ The Exchange is proposing similarly 
to remove of the 25,000 contract position and exercise limit for GBTC, 
BTC, and BITB, such that those funds will be subject to the position 
and exercise limits as determined by the position limit rules at Rule 
3120. The Exchange has provided information regarding GBTC, BTC, and 
BITB, including, among other things, information regarding trading 
volume, and the market capitalization of GBTC, BTC, and BITB and 
surveillance procedures that will apply. The Commission notes that the 
proposal raises no new or novel legal issues and would simply provide 
an additional venue for trading GBTC, BTC, and BITB with position and 
exercise limits that may be higher than 25,000 contracts. 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.\63\

    \61\ 17 CFR 240.19b-4(f)(6)(iii).

    \63\ 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 such 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 under 
Section 19(b)(2)(B) \64\ of the Act to determine whether the proposed 
rule change should be approved or disapproved.
