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

    The Exchange proposes to amend Rules 4.20 and 8.35 to permit 
options on the iShares Bitcoin Trust (``IBIT''), Grayscale Bitcoin 
Trust (``GBTC''), the Grayscale Bitcoin Mini Trust (``BTC''), and the 
Bitwise Bitcoin ETF (``BITB'') (each a ``Fund'' and, collectively, the 
``Funds'') to be eligible to trade as Flexible Exchange (``FLEX'') 
Equity Options. The text of the proposed rule change is provided in 
Exhibit 5.
    The text of the proposed rule change is also available on the 
Exchange's website (http://www.cboe.com/AboutCBOE/CBOELegalRegulatoryHome.aspx) and at the Exchange's Office of the 
Secretary.

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 Rule 4.20 (FLEX Option Classes) to 
permit options on the Funds to be eligible to trade as FLEX Equity 
Options.\3\ The Exchange notes that this proposal is competitive given 
that Nasdaq Phlx, LLC (``Phlx'') \4\ recently submitted a proposal to 
permit FLEX trading on options on IBIT and NYSE American, LLC (``NYSE 
American'') \5\ recently submitted a proposal to permit FLEX trading on 
options on GBTC, BTC, and BITB, both of which were recently approved by 
the Securities and Exchange Commission (the ``Commission'').
---------------------------------------------------------------------------

    \3\ FLEX Options are customized equity or index contracts that 
allow investors to tailor contract terms for exchange-listed equity 
and index options. See Rule 1.1 and generally Section C (FLEX 
Options). A FLEX Option on an equity security may be referred to as 
a ``FLEX Equity Option.'' See Rule 1.1.
    \4\ See Securities Exchange Act Release No. 103565 (July 29, 
2025), 90 FR 36233 (August 1, 2025) (SR-PHLX-2024-72) (Order 
Approving a Proposed Rule Change to Permit the Trading of FLEX 
Options on Shares of the iShares Bitcoin Trust ETF) (``Phlx FLEX 
Approval Order'').
    \5\ See Securities Exchange Act Release No. 103566 (July 29, 
2025), 90 FR 36250 (August 1, 2025) (SR-NYSEAMER-2024-78) (Order 
Approving a Proposed Rule Change, as Modified by Amendment No. 1, to 
Permit the Trading of FLEX Options on Shares of the Grayscale 
Bitcoin Trust, the Grayscale Bitcoin Mini Trust ETF, and the Bitwise 
Bitcoin ETF) (``NYSE FLEX Approval Order'').
---------------------------------------------------------------------------

    Each Fund is an ETF that holds bitcoin. GBTC, BTC and BITB are 
listed on NYSE Arca, Inc. (``NYSE Arca'').\6\ On

October 18, 2024, NYSE American received approval to list options on 
GBTC, BTC, and BITB.\7\ On April 11, 2025, the Exchange's proposal to 
list options on GBTC, BTC, and BITB became operative.\8\ IBIT is listed 
on The Nasdaq Stock Market LLC (``Nasdaq'').\9\ On September 20, 2024, 
Nasdaq ISE, LLC (``ISE'') received approval to list options on 
IBIT.\10\ On April 11, 2025, the Exchange's proposal to list options on 
IBIT became operative.\11\
---------------------------------------------------------------------------

    \6\ NYSE Arca received approval to list and trade Bitcoin-Based 
Commodity-Based Trust Shares in GBTC, BTC, and BITB pursuant to NYSE 
Arca Rule 8.201-E(c)(1). See Securities Exchange Act Release Nos.

of Filing of Amendment Nos. 4 and 5 and Order Granting Accelerated 
Approval of a Proposed Rule Change, as Modified by Amendment Nos. 1, 
4, and 5, To Permit the Listing and Trading of Options on the

    \11\ See Securities Exchange Act Release No. 102831 (April 11,

CBOE-2025-025) [sic].
---------------------------------------------------------------------------

    For options on each Fund, the position and exercise limits are 
25,000 contracts, as set forth in Rule 8.30, Interpretation and Policy 
.10 and pursuant to Rule 8.42, Interpretation and Policy .02, 
respectively, the lowest available limit.\12\
---------------------------------------------------------------------------

    \12\ The exercise limits for options on each Fund are the same 
as the position limits for each Fund as determined by Rule 8.30.10. 
See Rule 8.42, Interpretation and Policy .02. The Exchange is 
contemporaneously submitting a rule filing that would eliminate this 
25,000 contract position and exercise limit for the Fund options. If 
that filing becomes operative, the position and exercise limits for 
the Fund options would be determined in accordance with Rule 
8.30.02.
---------------------------------------------------------------------------

    FLEX Equity Options are not generally subject to position or 
exercise limits.\13\ Today, pursuant to Rule 4.20, Fund options are not 
approved for FLEX trading.\14\ Therefore, the 25,000-contract limit 
applicable to options on each Fund currently applies solely to non-FLEX 
Fund options.
---------------------------------------------------------------------------

    \13\ See Rule 8.35(c)(1) (subject to the exceptions enumerated 
in the rule ``there shall be no position limits for FLEX Equity 
options.'').
    \14\ Rule 4.20 also does not permit FLEX trading on options on 
except the Fidelity Wise Origin Bitcoin Fund, the Fidelity Ethereum 
Fund, the ARK 21Shares Bitcoin ETF, the Bitwise Ethereum ETF, the 
Grayscale Ethereum Trust, the Grayscale Ethereum Mini Trust, or the 
iShares Ethereum Trust [sic].
---------------------------------------------------------------------------

    The Exchange proposes to permit options on each Fund to trade as 
FLEX Equity Options and would require the aggregation of any FLEX and 
non-FLEX positions in the same underlying Fund for purposes of 
calculating the position and exercise limits applicable to each 
Fund.\15\
---------------------------------------------------------------------------

    \15\ See proposed Rules 4.20 (excluding IBIT, GBTC, BTC, and 
BITB options from the prohibition against FLEX trading); and 
8.35(c)(1)(C) (adopting the requirement that, for options on each 
Fund, the Exchange will aggregate any FLEX and non-FLEX positions in 
the same underlying ETF for purposes of calculating the position and 
exercise limits for that Fund, as set forth in Rule 8.30, 
Interpretation and Policy .10 (and pursuant to Rule 8.42, 
Interpretation and Policy .02).
---------------------------------------------------------------------------

    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.'' \16\ 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.'' \17\ Based on its 
review of the data and analysis provided by the Exchange, the 
Commission concluded that the current 25,000-contract position (and 
exercise) limit for non-FLEX options on each Fund satisfied these 
objectives.\18\
---------------------------------------------------------------------------

    \16\ See Fund Options Approval Order, 89 FR, at 84971; and IBIT 
Approval Order, 89 FR, at 78946.
    \17\ See id.
    \18\ See id.
---------------------------------------------------------------------------

    As proposed, for options on each Fund, the Exchange will aggregate 
any FLEX and non-FLEX positions in the same underlying Fund for 
purposes of calculating the 25,000-contract position and exercise 
limits. For each Fund, this proposed aggregated limit effectively 
restricts a market participant from holding positions that could result 
in the receipt of more than 2,500,000 shares, aggregated for FLEX and 
non-FLEX in the same underlying Fund (if that market participant 
exercised all its options). The Exchange believes that capping the 
aggregated position and exercise limits at 25,000 contracts, the lowest 
available limit, would be sufficient to address concerns related to 
manipulation and the protection of investors. The Exchange believes 
this number is conservative given the liquidity of each Fund.\19\
---------------------------------------------------------------------------

    \19\ See id.
---------------------------------------------------------------------------

    While the Exchange proposes an aggregated 25,000-contract position 
and exercise limit for options on each Fund, it nonetheless believes 
that, for the reasons set forth below, evidence exists to support a 
much higher position limit.\20\
---------------------------------------------------------------------------

    \20\ As noted above, the Exchange is contemporaneously 
submitting a proposed rule change to eliminate the 25,000 contract 
position and exercise limit for options on the funds, which would 
result in the position and exercise limits for the options on the 
funds being determined pursuant to Rule 8.30.02. This would 
ultimately result in an increase in the position and exercise limit 
for options on the Funds based on additional data regarding trading 
activity, to continue to balance any concerns regarding 
manipulation. A higher position and exercise limit would allow 
institutional investors to utilize Fund options for prudent risk 
management purposes. In this regard, the Exchange would address the 
impact of higher position (and exercise) limits on the proposed FLEX 
Fund options.
---------------------------------------------------------------------------

    In approving the options on GBTC, BTC, and BITB, the Commission 
considered and reviewed an analysis that the exercisable risk 
associated with a position limit of 25,000 contracts represented only 
0.9%, 0.7%, and 3.6% of the outstanding shares of GBTC, BTC and BITB, 
respectively.\21\ The Commission also considered and reviewed the 
Exchange's arguments that with a 25,000-contract limit for each Fund: 
(i) the 284,570,100 GBTC shares outstanding, 114 market participants 
would have to simultaneously exercise their positions to place GBTC 
under stress; (ii) the 366,950,100 BTC shares outstanding, meant that 
147 market participants would have to simultaneously exercise their 
same-side positions to place BTC under stress; and (iii) the 68,690,000 
BITB shares outstanding, meant that 27 market participants would have 
to simultaneously exercise their same-side positions to place BITB 
under stress.\22\ Based on the Commission's review of this information 
and analysis, the Commission concluded that the 25,000-contract 
position and exercise limit for options on each Fund would address 
concerns related to manipulation and investor protection and deemed 
this

[[Page 40671]]

limit conservative and therefore appropriate given the liquidity of 
each Fund.\23\
---------------------------------------------------------------------------

    \21\ See Fund Options Approval Order, 89 FR, at 84971. Data 
represents figures from FactSet as of August 30, 2024.
    \22\ See Fund Options Approval Order, 89 FR, at 84971.
    \23\ See id.
---------------------------------------------------------------------------

    Similarly, in approving the options on IBIT, the Commission 
considered and reviewed ISE's analysis that the exercisable risk 
associated with a position limit of 25,000 contracts represented only 
0.4% of the outstanding shares of IBIT.\24\ The Commission also has 
considered and reviewed the ISE's statement that with a position limit 
of 25,000 contracts on the same side of the market and 611,040,00 
shares of IBIT outstanding, 244 market participants would have to 
simultaneously exercise their positions to place IBIT under stress.\25\ 
Based on the Commission's review of this information and analysis, the 
Commission concluded that the proposed position and exercise limits 
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.\26\ Each Fund would otherwise qualify for 
a 250,000-contract limit, pursuant to Rule 8.30, Interpretation and 
Policy .02(e), which requires that, for the most recent six-month 
period, trading volume for the underlying security is at least 
100,000,000 shares.\27\
---------------------------------------------------------------------------

    \24\ See IBIT Approval Order, 89 FR, at 78946.
    \25\ See id.
    \26\ See id.
    \27\ See Rule 8.30, Interpretation and Policy .02 (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.
---------------------------------------------------------------------------

    With respect to the GBTC, BTC, and BITB, the Exchange reviewed the 
data presented by NYSE American in its filing with respect to shares 
outstanding (and corresponding market capitalization), number of 
beneficial holders, and trading volume. As of November 25, 2024, the 
below Funds had the following number of shares outstanding (and 
corresponding market capitalization) for the preceding six months and 
the average daily volume (``ADV'') for the preceding three months.\28\
---------------------------------------------------------------------------

    \28\ The market capitalization of GBTC was determined by 
multiplying a settlement price ($75.42) by the number of shares 
outstanding (273,950,100); the market capitalization of BTC was 
determined by multiplying a settlement price ($42.16) by the number 
of shares outstanding (82,939,964); 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.

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

    Also, as of November 25, 2024, there were 19,787,762 bitcoins in 
circulation.\29\ At a price of $94,830 per bitcoin,\30\ that equates to 
a market capitalization of greater than $1.876 trillion. If a position 
and exercise limit of 250,000 contracts were considered for each Fund, 
the exercisable risk would represent 9.13% \31\ of the GBTC shares 
outstanding; 30.14% \32\ of BTC shares outstanding; and 31.27% \33\ of 
BITB shares outstanding. Given the liquidity of BTC and BITB, the 
current 25,000 position and exercise limit appears extremely 
conservative.
---------------------------------------------------------------------------

    \29\ See https://www.coingecko.com/en/coins/bitcoin.
    \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/273,950.100 GBTC shares 
outstanding).
    \32\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/82,939,964 BTC shares 
outstanding).
    \33\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/79,950,100 BITB shares 
outstanding).
---------------------------------------------------------------------------

    Similarly, with respect to IBIT, the Exchange reviewed the data 
presented by Phlx in its filing with respect to shares outstanding (and 
corresponding market capitalization), number of beneficial holders, and 
trading volume. As of November 26, 2024, the market capitalization for 
IBIT was $46,783,480,800 \34\ with an ADV, for the preceding three 
months prior to November 26, 2024, of 39,421,877 shares. At a price of 
$94,830,\35\ that equates to a market capitalization of greater than 
$1.876 trillion US.
---------------------------------------------------------------------------

    \34\ 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 26, 2024. See 
https://www.ishares.com/us/products/333011/ishares-bitcoin-trust-etf.
    \35\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
---------------------------------------------------------------------------

    Despite the proposed addition of FLEX trading in options on IBIT, 
GBTC, BTC, and BITB (collectively, ``FLEX Fund Options''), the Exchange 
would continue to limit to 25,000 the number of options on each Fund 
traded on the Exchange that an investor, acting alone or in concert 
with others directly or indirectly, may control and thereby mitigate 
potential manipulation. The Exchange believes that allowing FLEX Fund 
Options is consistent with the Act given FLEX trading is permitted 
today in other ETFs that hold a commodity, such as SPDR Gold Shares 
(``GLD'') and iShares Silver Trust (``SLV'').\36\
---------------------------------------------------------------------------

    \36\ GLD and SLV, like the each of the Funds, holds one asset in 
trust.
---------------------------------------------------------------------------

    Further, the Exchange believes that the share creation and 
redemption process unique to ETFs would mitigate any potential risk of 
manipulation in FLEX Fund Options. The creation and redemption process 
is designed to ensure that an ETF's price closely tracks the value of 
its underlying asset(s). For example, if a market participant exercised 
a long call position for 25,000 contracts and purchased 2,500,000 
shares of GBTC and this purchase resulted in the value of GBTC shares 
to trade at a premium to the value of the (underlying) bitcoin held by 
GBTC, the Exchange believes that other market participants would 
attempt to arbitrage this price difference by selling short GBTC shares 
while concurrently purchasing bitcoin. Those market participants 
(arbitrageurs) would then deliver cash to GBTC and receive shares of 
GBTC, which would be used to close out any previously established short 
position in GBTC. Thus, this creation and redemption process would 
significantly reduce the potential risk of price dislocation between 
the value of shares in each Fund and the value of bitcoin holdings.
    The Exchange understands that FLEX Equity Options on ETFs are 
currently traded in the over-the-counter (``OTC'')

[[Page 40672]]

market by a variety of market participants, e.g., hedge funds, 
proprietary trading firms, and pension funds, to name a few. The 
Exchange believes there is room for significant growth if a comparable 
product were introduced for trading on a regulated market. The Exchange 
expects that users of these OTC products would be among the primary 
users of FLEX Fund Options. The Exchange also believes that the trading 
of FLEX Fund Options would allow these same market participants to 
better manage the risk associated with the volatility of positions in 
the underlying ETF (i.e., IBIT, GBTC, BTC, or BITB) given the enhanced 
liquidity that an exchange-traded product would bring.
    Additionally, the Exchange believes that FLEX Fund Options traded 
on the Exchange would have three important advantages over the 
contracts that are traded in the OTC market. First, as a result of 
greater standardization of contract terms, exchange-traded contracts 
should develop more liquidity. Second, counterparty credit risk would 
be mitigated by the fact that the contracts are issued and guaranteed 
by The Options Clearing Corporation (``OCC''). Finally, the price 
discovery and dissemination provided by the Exchange and its members 
would lead to more transparent markets. The Exchange believes that its 
ability to offer FLEX Fund Options would aid it in competing with the 
OTC market and at the same time expand the universe of products 
available to interested market participants. The Exchange believes that 
an exchange-traded alternative may provide a useful risk management and 
trading vehicle for market participants and their customers.
    The Exchange has analyzed its capacity and represents that it and 
The Options Price Reporting Authority (``OPRA'') have the necessary 
systems capacity to handle the additional traffic associated with the 
listing of FLEX Fund Options. The Exchange believes any additional 
traffic that would be generated from the trading of FLEX Fund Options 
would be manageable. The Exchange believes Trading Permit Holders 
(``TPHs'') will not have a capacity issue as a result of this proposed 
rule change. The Exchange also represents that it does not believe this 
proposed rule change will cause fragmentation of liquidity. The 
Exchange will monitor the trading volume associated with the additional 
options series listed as a result of this proposed rule change and the 
effect (if any) of these additional series on market fragmentation and 
on the capacity of the Exchange's automated systems.
    Today, the Exchange has an adequate surveillance program in place 
for options. Cboe intends to apply those same program procedures to 
options on the FLEX Fund Options that it applies to the Exchange's 
other options products.\37\ Cboe's market surveillance staff would have 
access to the surveillances it conducts, as well as that the Financial 
Industry Regulatory Authority (``FINRA'') conducts on its behalf with 
respect to the FLEX Fund Options and would review activity in the 
underlying Funds when conducting surveillances for market abuse or 
manipulation in the FLEX Fund Options. Additionally, the Exchange is 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, options, and futures markets. In addition to obtaining 
information from its affiliated markets, the Exchange would be able to 
obtain information regarding trading in shares of the Funds from their 
primary listing markets and from other markets that trade shares of the 
Funds through ISG. In addition, Cboe has a Regulatory Services 
Agreement with the Financial Industry Regulatory Authority (``FINRA'') 
for certain market surveillance, investigation and examinations 
functions. Pursuant to a multi-party 17d-2 joint plan, all options 
exchanges allocate amongst themselves and FINRA responsibilities to 
conduct certain options-related market surveillance that are common to 
rules of all options exchanges.\38\
---------------------------------------------------------------------------

    \37\ The surveillance program includes surveillance patterns for 
price and volume movements as well as patterns for potential 
manipulation (e.g., spoofing and marking the close).
    \38\ Section 19(g)(1) of the Act, among other things, requires 
every self-regulatory organization (``SRO'') registered as a 
national securities exchange or national securities association to 
comply with the Act, the rules and regulations thereunder, and the 
SRO's own rules, and, absent reasonable justification or excuse, 
enforce compliance by its members and persons associated with its 
members. See 15 U.S.C. 78q(d)(1) and 17 CFR 240.17d-2. Section 
17(d)(1) of the Act allows the Commission to relieve an SRO of 
certain responsibilities with respect to members of the SRO who are 
also members of another SRO (``common members''). Specifically, 
Section 17(d)(1) allows the Commission to relieve an SRO of its 
responsibilities to: (i) receive regulatory reports from such 
members; (ii) examine such members for compliance with the Act and 
the rules and regulations thereunder, and the rules of the SRO; or 
(iii) carry out other specified regulatory responsibilities with 
respect to such members.
---------------------------------------------------------------------------

    The proposed rule change is designed to allow investors seeking to 
trade options on the Funds to utilize FLEX Fund Options. The Exchange 
believes that offering innovative products flows to the benefit of the 
investing public. A robust and competitive market requires that 
exchanges respond to members' evolving needs by constantly improving 
their offerings. Such efforts would be stymied if exchanges were 
prohibited from offering innovative products such as the proposed FLEX 
Fund Options. The Exchange believes that introducing FLEX Fund Options 
would further broaden the base of investors that use FLEX Equity 
Options (and options on the Funds in general) to manage their trading 
and investment risk, including investors that currently trade in the 
OTC market for customized options. The proposed rule change is also 
designed to encourage market makers to shift liquidity from the OTC 
market on the Exchange, which, it believes, will enhance the process of 
price discovery conducted on the Exchange through increased order flow.
    As discussed herein, the Exchange does not believe that this 
proposed rule change raises any unique regulatory concerns because the 
proposal to aggregate FLEX and non-FLEX option positions in each Fund 
at the (most conservative) 25,000-contract position and exercise limit, 
which currently applies solely to non-FLEX options on each Fund, should 
provide an adequate safeguard.
2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Securities Exchange Act of 1934 (the ``Act'') and the rules and 
regulations thereunder applicable to the Exchange and, in particular, 
the requirements of Section 6(b) of the Act.\39\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \40\ 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) \41\ requirement that the rules of an exchange not be 
designed

to permit unfair discrimination between customers, issuers, brokers, or 
dealers.

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

    The Exchange believes that the proposal to permit FLEX Fund Options 
would remove impediments to and perfect the mechanism of a free and 
open market. The Exchange believes that offering FLEX Fund Options will 
benefit investors by providing them with an additional, relatively 
lower cost investing tool to gain exposure to the price of bitcoin and 
provide a hedging vehicle to meet their investment needs in connection 
with a bitcoin-related product. Moreover, the proposal would broaden 
the base of investors that use FLEX Options to manage their trading and 
investment risk, including investors that currently trade in the OTC 
market for customized options. By trading a product in an exchange-
traded environment (that is currently being used in the OTC market), 
the Exchange would be able to compete more effectively with the OTC 
market. The Exchange believes the proposed rule change is designed to 
prevent fraudulent and manipulative acts and practices in that it would 
lead to the migration of options currently trading in the OTC market to 
trading to the Exchange. Also, any migration to the Exchange from the 
OTC market would result in increased market transparency and enhance 
the process of price discovery conducted on the Exchange through 
increased order flow.
    Additionally, the Exchange believes the proposed rule change is 
designed to remove impediments to and to perfect the mechanism for a 
free and open market and a national market system, and, in general, to 
protect investors and the public interest in that it should create 
greater trading and hedging opportunities and flexibility. The proposed 
rule change should also result in enhanced efficiency in initiating and 
closing out positions and heightened contra-party creditworthiness due 
to the role of OCC as issuer and guarantor of FLEX Fund Options. 
Further, the proposed rule change would result in increased competition 
by permitting the Exchange to offer products that are currently used in 
the OTC market.
    The Exchange does not believe that this proposed rule change raises 
any unique regulatory concerns because the proposal to aggregate any 
FLEX and non-FLEX options in each Fund at the current (and most 
conservative) 25,000-contract limit should provide an adequate 
safeguard. As noted herein, the purpose of position (and exercise) 
limits is 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. The Exchange believes the 
proposal will benefit investors and public interest because the 
aggregated position and exercise limits for (FLEX and non-FLEX) options 
on the same underlying Fund at 25,000 contracts, the lowest limit 
available in options, would address concerns related to manipulation 
and protection of investors as this number is conservative and 
therefore appropriate given the sufficient liquidity in each Fund.
    The Exchange believes that offering innovative products benefits 
the investing public. A robust and competitive market requires that 
exchanges respond to the evolving needs of their members by constantly 
improving their offerings. Such efforts would be stymied if exchanges 
were prohibited from offering innovative products such as the proposed 
FLEX Fund Options. The Exchange does not believe that allowing FLEX 
Fund Options would render the marketplace for equity options more 
susceptible to manipulative practices.
    Finally, the Exchange represents that it has an adequate 
surveillance program in place to detect manipulative trading in FLEX 
Fund Options. Regarding the proposed FLEX Fund Options, the Exchange 
would use the same surveillance procedures utilized for FLEX Options 
currently listed on the Exchange (as well as for non-FLEX options on 
each Fund). For surveillance purposes, the Exchange would have access 
to information regarding trading activity in the underlying Funds 
(i.e., IBIT, GBTC, BTC, and BITB). In light of surveillance measures 
related to both options and the underlying Funds, the Exchange believes 
that existing surveillance procedures are designed to deter and detect 
possible manipulative behavior which might potentially arise from 
listing and trading the proposed FLEX Fund Options.

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. The Exchange does not 
believe that its proposed rule change will impose any burden on 
intramarket competition as all market participants would have the 
option of utilizing the FLEX Fund Options. The proposed rule change is 
designed to allow investors seeking option exposure to bitcoin to trade 
FLEX Fund Options. Moreover, the Exchange believes that the proposal to 
permit FLEX Fund Options would broaden the base of investors that use 
FLEX Options to manage their trading and investment risk, including 
investors that currently trade in the OTC market for customized 
options.
    The Exchange does not believe that its proposed rule change will 
impose any burden on intermarket competition as the Exchange operates 
in a highly competitive market in which market participants can readily 
direct order flow to competing venues. The proposed rule change would 
support that intermarket competition by allowing the Exchange to offer 
additional functionality to TPHs. The Exchange believes that the 
proposed FLEX Fund Options will increase the variety of options 
products available for trading in general and bitcoin-related products 
in particular and, as such, will provide a valuable tool for investors 
to manage risk. As such, the Exchange believes that this proposal does 
not create an undue burden on intermarket competition. Rather, the 
Exchange believes that the proposed rule would bolster intermarket 
competition by promoting fair competition among individual markets. As 
noted above, this is a competitive filing based on a similar proposals 
submitted by NYSE American and Phlx, which were recently approved by 
the Commission.\42\

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

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

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

    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 \43\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\44\
---------------------------------------------------------------------------

    \43\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \44\ 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.

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

[[Page 40674]]

    A proposed rule change filed under Rule 19b-4(f)(6) \45\ 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),\46\ the 
Commission may designate a shorter time if such action is consistent 
with the protection of investors and the public interest. The Exchange 
has asked the Commission to waive the 30-day operative delay so that 
the proposal may become operative immediately upon filing. The 
Commission previously approved FLEX trading on IBIT, BTC, GBTC, and 
BITB on other exchanges as discussed herein.\47\ The Commission does 
not believe that this proposed rule change raises new or novel legal 
issues, and would allow the Exchange to begin offering FLEX Fund 
Options without delay. Therefore, the Commission believes that waiver 
of 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.\48\
---------------------------------------------------------------------------

    \45\ 17 CFR 240.19b-4(f)(6).
    \46\ 17 CFR 240.19b-4(f)(6)(iii).
    \47\ See supra notes 4-5.
    \48\ 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.
