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 Rules 4.13, 5.1, and 8.32. First, 
the Exchange proposes to amend Rule 4.13(e), which governs its 
Nonstandard Expirations Program (``Program''), to permit P.M.-settled 
options on the Cboe Bitcoin U.S. ETF Index (``CBTX'') and the Mini-Cboe 
Bitcoin U.S. ETF Index (``MBTX'') that expire any Monday, Tuesday, 
Wednesday, Thursday, or Friday (other than the third Friday-of-the-
month (``Expiration Friday'') or days that coincide with an end-of-
month expiration) (``Weekly Expirations'') and that expire on the last 
trading day of the month (``EOMs''). Currently under the Program, the 
Exchange is permitted to list P.M.-settled options on any broad-based 
index eligible for standard trading that expire on: (1) any Monday, 
Tuesday, Wednesday, Thursday, or Friday (other than the third Friday-
of-the-month or days that coincide with an EOM expiration) and (2) the 
last trading day of the month.\7\ The proposal expands the availability 
of Weekly and EOM expirations to CBTX and MBTX options, which are 
narrow-based index options eligible for standard options trading.\8\
---------------------------------------------------------------------------

    \7\ See Rule 4.13(e).
    \8\ The Exchange notes these options are currently eligible for 
the Monthly Options Series program pursuant to Rule 4.13(a)(2)(C), 
which permits p.m.-settled options that expire on the last trading 
day of the month (as do options with EOM expirations). The Exchange 
proposes to make these options eligible for the EOM expirations 
pursuant to the Nonstandard Expiration for consistency since the 
Exchange is proposing to make these options eligible for the Weekly 
Expirations, which are part of the Nonstandard Expiration Program.
---------------------------------------------------------------------------

    The Nonstandard Expiration Program will apply to CBTX and MBTX 
options in the same manner as it currently applies to broad-based index 
options. Weekly and EOM Expirations are subject to all provisions of 
Rule 4.13 and treated the same as options on the same underlying index 
that expire on the third Friday of the expiration month; provided, 
however, that Weekly and EOM Expirations are P.M.-settled, and new 
series in Weekly and EOM Expirations may be added up to and including 
on the expiration date for an expiring Weekly or EOM Expiration.
    The maximum number of expirations that may be listed for each 
Weekly Expiration (i.e., a Monday expiration, Tuesday expiration, 
Wednesday expiration, Thursday expiration, or Friday expiration, as 
applicable) and each EOM expiration in a given class is the same as the 
maximum number of expirations permitted in Rule 4.13(a)(2) for standard 
options on the same index.\9\ Weekly Expirations need not be for 
consecutive Monday, Tuesday, Wednesday, Thursday, or Friday expirations 
as applicable; however, the expiration date of a nonconsecutive 
expiration may not be beyond what would be considered the last 
expiration date if the maximum number of expirations were listed 
consecutively. Weekly Expirations that are first listed in a given 
class may expire up to four weeks from the actual listing date. 
Similarly, EOM expirations need not be for consecutive end of month 
expirations; however, the expiration date of a non-consecutive 
expiration may not be beyond what would be considered the last 
expiration date if the maximum number of expirations were listed 
consecutively. EOM Expirations that are first listed in a given class 
may expire up to four weeks from the actual listing date. If the 
Exchange lists EOMs and Weekly Expirations in a given class, the 
Exchange will list an EOM instead of a Weekly Expiration that expires 
on the same day in the given class. Other expirations in the same class 
are not counted as part of the maximum number of Weekly or EOM 
Expirations for an applicable index class.
---------------------------------------------------------------------------

    \9\ The proposed rule change deletes the phrase ``broad-based'' 
in several places in Rule 4.13(e), as the proposal would result in 
the provisions within that Rule applying to indexes that are not 
broad-based. These administrative changes merely accommodate the 
proposed expansion of the Nonstandard Expiration Program. The 
Exchange is not proposing to expand the Nonstandard Expiration 
Program to narrow-based indices generally, but rather only to MBTX 
and CBTX options.
---------------------------------------------------------------------------

    If the Exchange is not open for business on a respective Monday, 
the normally Monday expiring Weekly Expirations will expire on the 
following business day. If the Exchange is not open for business on a 
respective Tuesday, Wednesday, Thursday, or Friday, the normally 
Tuesday, Wednesday, Thursday, or Friday expiring Weekly Expirations 
will expire on the previous business day. If two different Weekly 
Expirations on an index would expire on the same day because the 
Exchange is not open for business on a certain weekday, the Exchange 
will list only one of such Weekly Expirations. In addition, pursuant to 
Rule 4.13(e)(3), transactions in expiring index options with Weekly and 
EOM Expirations may be effected on the Exchange between the hours of 
9:30 a.m. and 4:00 p.m. on their last trading day (Eastern Time).
    Second, the Exchange proposes to amend Rule 4.13(c), which governs 
quarterly index expirations (``QIXs''), to add CBTX and MBTX options to 
the list of options in Rule 4.13(c) that are eligible for quarterly 
index expirations (``QIXs''), which are currently available for options 
on the S&P 100 Index (``OEX options'') S&P 500 Index (``SPX options''), 
Mini-S&P 500 Index (``XSP options''), the Russell 2000 Index (``RUT 
options''), and Mini-Russell 2000 Index (``MRUT options'').\10\ 
Pursuant to Rule 4.13(c), there may be up to eight near-term quarterly 
expirations open for trading in a class and these options will be P.M.-
settled. The QIX program will apply to CBTX and MBTX options in the 
same manner as it currently applies to the other options currently 
eligible for those expirations. QIXs are subject to all provisions of 
Rule 4.13 and treated the same as options on the same underlying index 
that expire on the third Friday of the expiration month, except that 
QIXs, are P.M.-settled.
---------------------------------------------------------------------------

    \10\ The Exchange notes CBTX and MBTX options are currently 
eligible for the Quarterly Options Series program pursuant to Rule 
4.13(a)(2)(B), which permits P.M.-settled options that expire on the 
last trading day of the quarter (as do QIXs). The Exchange proposes 
to make these options eligible for QIXs for consistency, since QIXs 
are currently available for certain index options available for 
trading on the Exchange (which options are also eligible for the 
Nonstandard Expirations Program).

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

[[Page 24182]]

    Third, the Exchange proposes to amend Rule 4.13, Interpretation and 
Policy .13, to permit the listing of P.M.-settled CBTX and MBTX options 
that expire on Expiration Fridays. Currently, pursuant to Rule 4.13, 
Interpretation and Policy .13, the Exchange is permitted to list P.M.-
settled SPX options, XSP options, RUT options, and MRUT options that 
expire on Expiration Fridays. Combined with the proposed rule change 
above to permit the Exchange to list P.M.-settled CBTX and MBTX options 
with Weekly Expirations, the Exchange would be permitted to list P.M.-
settled CBTX and MBTX options with expirations on all Fridays (in 
addition to all other days of the week). CBTX and MBTX options that are 
P.M.-settled and expire on Expiration Fridays are subject to all 
provisions of Rule 4.13 and treated the same as A.M.-settled CBTX and 
MBTX options, except that they are P.M.-settled.
    Finally, the Exchange proposes to amend Rule 5.1, which governs 
trading days and hours, in conjunction with the proposed addition of 
CBTX and MBTX options that are P.M.-settled and expire on Expiration 
Friday. Rule 5.1(b)(2)(C) currently provides that on their last trading 
day, Regular Trading Hours for index options with Nonstandard 
Expirations, as well as expiring P.M.-settled SPX, XSP, RUT, and MRUT 
options, may be effected on the Exchange between 9:30 a.m. and 4:00 
p.m. Eastern Time \11\ (as opposed to the 9:30 a.m. to 4:15 p.m. 
Regular Trading Hours for options with those expirations that are non-
expiring). The proposed rule change amends Rule 5.1(b)(2)(C) to include 
CBTX and MBTX P.M.-settled options.\12\ The primary listing markets for 
the component securities that comprise the Cboe Bitcoin U.S. ETF Index 
and the Mini-Cboe Bitcoin U.S. ETF Index close trading in those 
securities at 4:00 p.m., just as the primary listing markets for the 
component securities that comprise the S&P 500, Mini-S&P 500, Russell 
2000, and Mini-Russell 2000 Indexes close trading at 4:00 p.m. The 
primary listing exchanges for the component securities disseminate 
closing prices for the component securities, which are used to 
calculate the exercise settlement value of these indexes. The Exchange 
believes that, under normal trading circumstances, the primary listing 
markets have sufficient bandwidth to prevent any data queuing that may 
cause any trades that are executed prior to the closing time from being 
reported after 4:00 p.m. If trading in expiring CBTX and MBTX P.M.-
settled options continued an additional fifteen minutes until 4:15 p.m. 
on their last trading day, these expiring options would be trading 
after the settlement index value for those expiring options was 
calculated. Therefore, in order to mitigate potential investor 
confusion and the potential for increased costs to investors as a 
result of potential pricing divergence at the end of the trading day, 
the Exchange believes that it is appropriate to cease trading in the 
expiring CBTX and MBTX P.M.-Settled options at 4:00 p.m., as it already 
does for expiring P.M.-settled SPX, XSP, RUT, and MRUT options that 
expire on Expiration Fridays and for expiring broad-based indexes with 
Nonstandard Expirations (which are P.M.-settled) for the same 
aforementioned reasons.\13\ The Exchange does not believe that the 
proposed rule change will impact volatility on the underlying cash 
market comprising the Cboe Bitcoin U.S. ETF Index and the Mini-Cboe 
Bitcoin U.S. ETF Index at the close on Expiration Fridays, as it 
already closes trading on the last trading day for expiring P.M.-
settled index options at 4:00 p.m., which the Exchange does not believe 
has had an adverse impact on fair and orderly markets on Expiration 
Fridays for the underlying securities comprising the corresponding 
indexes.\14\
---------------------------------------------------------------------------

    \11\ See Rule 1.6, which states that unless otherwise specified, 
all times in the Rules are Eastern Time.
    \12\ Current Rule 5.1(b)(2)(C) would apply to CBTX and MBTX 
options with Nonstandard Expirations and QIXs, as proposed; 
therefore, the addition of CBTX and MBTX P.M.-settled options to the 
list of options set forth in this Rule covers these options that 
expire on Expiration Fridays.
    \13\ See Securities Exchange Act Release Nos. 68888 (February 8, 
2013), 78 FR 10668 (February 14, 2013) (SR-CBOE-2012-120) (``SPXPM 
Pilot Approval Order''); 70087 (July 31, 2013), 78 FR 47809 (August 
6, 2013) (SR-CBOE-2013-055) (``XSPPM Pilot Approval Order''); and 
91067 (February 5, 2021), 86 FR 9108 (February 11, 2021) (SR-CBOE-
2020-116) (``MRUTPM Pilot Approval Order'').
    \14\ See Securities Exchange Act Release Nos. 98454 (September 
20, 2023), 88 FR 66103 (September 26, 2023) (SR-CBOE-2023-005) 
(``SPXPM Permanent Approval Order''); and 98455 (September 20, 
2023), 88 FR 66073 (September 26, 2023) (SR-CBOE-2023-019) (``XSPPM 
and MRUTPM Permanent Approval Order'').
---------------------------------------------------------------------------

    As noted above, the Exchange may currently list P.M.-settled CBTX 
and MBTX options with expirations on the last calendar of the month and 
quarter.\15\ As a result, it is already possible for CBTX and MBTX 
options to be P.M.-settled and to expire on any day of the week (as the 
end of the month or the end of a quarter may fall on any day of the 
week). The Exchange also already allows CBTX and MBTX options to expire 
on Thursdays for normally Friday expiring options when the Exchange is 
not open for business on a respective Friday. Further, CBTX and MBTX 
options are available for FLEX trading pursuant to Rule 4.20, and thus, 
users may select expiration dates for these FLEX options for any day of 
the week and may select p.m.-settlement.
---------------------------------------------------------------------------

    \15\ See Rule 4.13(a)(2)(C) and (B), respectively.
---------------------------------------------------------------------------

    The Exchange believes that the introduction of Weekly Expirations 
and Expiration Friday expirations that are P.M.-settled for CBTX and 
MBTX will provide market participants with additional hedging tools and 
greater trading opportunities, regardless of in which index option 
market they participate. By offering expanded expirations along with 
the current standard A.M.-settled expirations (as well as P.M.-settled 
monthly and quarterly expirations), the proposed rule change will allow 
market participants to purchase options on CBTX and MBTX available for 
trading on the Exchange in a manner more aligned with specific timing 
needs (such as to hedge special events) and more effectively tailor 
their investment and hedging strategies and manage their portfolios. In 
particular, the proposed rule change will allow market participants to 
roll their positions on more trading days, thus with more precision, 
spread risk across more trading days and incorporate daily changes in 
the markets, which may reduce the premium cost of buying protection. 
For example, the Exchange believes that market participants may be 
paying for more protection than needed if they are seeking to hedge 
weekend or special event risk that occurs. Therefore, the Exchange 
believes that P.M.-settled daily expirations (including on all Fridays) 
would allow market participants to purchase an option based on their 
needed timing and allow them to tailor their investment or hedging 
needs more effectively. In addition, because P.M.-settlement permits 
trading throughout the day on the day the contract expires, the 
Exchange believes this will permit market participants to more 
effectively manage overnight risk and trade out of their positions up 
until the time the contract settles.
    The Exchange believes there is sufficient investor interest and 
demand in Weekly Expirations and Expiration Friday P.M.-settled 
expirations for CBTX and MBTX options to warrant inclusion in the 
Program and in the Rules, and that the Program and the Rules, as 
amended, will continue to provide investors with additional means of 
managing their risk exposures and carrying out their investment 
objectives.\16\
---------------------------------------------------------------------------

    \16\ The Exchange currently may list Weekly and EOM Expirations 
for any broad-based index option pursuant to the Program, and lists 
Expiration Friday P.M.-settled expirations pursuant to the Rules, 
for SPX, XSP, RUT, and MRUT.

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

[[Page 24183]]

    With regard to the impact of this proposal on system capacity, the 
Exchange has analyzed its capacity and represents that it believes that 
the Exchange and OPRA have the necessary systems capacity to handle any 
potential additional traffic associated with trading of P.M.-settled 
Weekly and Expiration Friday expirations for CBTX and MBTX options. The 
Exchange does not believe that its Trading Permit Holders (``TPHs'') 
will experience any capacity issues as a result of this proposal and 
represents that it will monitor the trading volume associated with any 
possible additional CBTX and MBTX options series listed as a result of 
this proposal and the effect (if any) of these additional series on 
market fragmentation and on the capacity of the Exchange's automated 
systems.
    In addition to this, the Exchange believes that its existing 
surveillance and reporting safeguards in place are adequate to deter 
and detect possible manipulative behavior which might arise from 
listing and trading CBTX and MBTX P.M.-Settled options with Weekly 
Expirations or Expiration Friday expirations (as the Exchange currently 
applies these to CBTX and MBTX options that are P.M.-settled with 
monthly and quarterly expirations) and will support the protection of 
investors and the public interest. Furthermore, the trading of CBTX and 
MBTX options with Weekly and P.M.-settled Expiration Friday expirations 
will be subject to the same rules that currently govern the trading of 
these options with other expirations, including governing customer 
accounts, position and exercise limits,\17\ margin requirements and 
trading halt procedures, among other Rules, which are designed to 
prevent fraudulent and manipulative acts and practices.
---------------------------------------------------------------------------

    \17\ The proposed rule change amends Rule 8.32(f) to provide 
that positions in Nonstandard Expiration Program series will be 
aggregated with positions in options contracts in the same index 
class. Therefore, CBTX and MBTX options positions that have 
Nonstandard Expirations will be aggregated for purposes of position 
limits with positions in CBTX and MBTX options, respectively with 
other expirations (including short-term, monthly, and quarterly 
expirations). This is consistent with the treatment of positions for 
purposes of position limits for other classes that participate in 
the Nonstandard Expiration Program. See Rule 8.31(b). Pursuant to 
Rule 8.42(b), which provides that the exercise limits for index 
options (including CBTX and MBTX options) are equivalent to the 
position limits set forth in Rule 8.32. Pursuant to Rule 8.32(a) and 
8.42(b), the current position and exercise limits for CBTX and MBTX 
options are 24,000 contracts (and may not be more than 31,500 
without rule changes). Therefore, investors would not be able to 
maintain significant open interest in these options, which may 
further prevent investors from being able to impact the value of the 
index.
---------------------------------------------------------------------------

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.\18\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \19\ 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 facilitation 
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) \20\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.
---------------------------------------------------------------------------

    \18\ 15 U.S.C. 78f(b).
    \19\ 15 U.S.C. 78f(b)(5).
    \20\ Id.
---------------------------------------------------------------------------

    In particular, the Exchange believes that the proposed rule change 
will 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. The Exchange believes that the 
introduction of P.M.-settled Weekly and Expiration Friday expirations 
for CBTX and MBTX options (rather than offering those expirations for 
just broad-based indexes) will provide investors with expanded hedging 
tools and greater trading opportunities and flexibility in additional 
index option markets.\21\ As a result, investors will have additional 
means to manage their risk exposures and carry out their investment 
objectives. By offering expanded expirations for CBTX and MBTX options 
(along with the currently available P.M.-settled monthly and quarterly 
options and standard A.M.-settled options), the proposed rule change 
will allow market participants to purchase options on two additional 
index options available for trading on the Exchange in a manner more 
aligned with specific timing needs and more effectively tailor their 
investment and hedging strategies and manage their portfolios. For 
example, the proposed rule change will allow market participants to 
roll their positions in CBTX and MBTX options on more trading days, 
thus with more precision, spread risk across more trading days and 
incorporate daily changes in the markets, which may reduce the premium 
cost of buying protection. The Exchange represents that it believes 
that it has the necessary systems capacity to support any additional 
traffic associated with trading of CBTX and MBTX options with Weekly 
and Expiration Friday (P.M.-settled) expirations and does not believe 
that its TPHs will experience any capacity issues as a result of this 
proposal.
---------------------------------------------------------------------------

    \21\ CBTX and MBTX options may already be listed with P.M.-
settlement and expirations on the last calendar day of the month or 
quarter pursuant to Rule 4.13(a)(2)(C) and (B), respectively; 
therefore, the additional series that this proposed rule would 
permit to be listed are P.M.-settled Weeklys and Expiration Friday 
expirations. The proposed rule change merely adds these options to 
different programs within the Rules that permit these same 
expirations for consistency within the Rules.
---------------------------------------------------------------------------

    The Exchange does not believe that the addition of CBTX and MBTX 
options to the Nonstandard Expirations Program, to the P.M.-settled 
Expiration Friday program, or the QIX program will raise any 
prohibitive regulatory concerns, nor adversely impact fair and orderly 
markets on expiration days. The Exchange has not experienced any 
meaningful regulatory concerns, nor adverse impact on fair and orderly 
markets, in connection with these programs, nor with the listing of 
CBTX and MBTX options that are P.M.-settled and expire on the last 
calendar day of the month and quarter (as the Exchange currently does) 
and is unaware of any reason why adding P.M.-settled options with 
expirations each day of the week for CBTX and MBTX options (which 
overlie a narrow-based index rather than a broad-based index) would be 
create such concerns or impact. Particularly, the Exchange does not 
believe increases in the number of P.M.-settled options series and 
expirations will have any significant adverse economic impact on the 
futures, index, or underlying index component securities markets (the 
Exchange notes there are currently no futures or securities futures 
listed on the underlying indexes). The Exchange believes that the 
proposed rule change will provide investors with greater trading and 
hedging opportunities and flexibility, allowing them to transact in 
CBTX and MBTX options in a manner more aligned with specific timing 
needs and more effectively tailor their investment and hedging 
objectives by listing these options that expire each trading day of the 
week, in addition to

[[Page 24184]]

options that expire at the end of calendar month and quarter (which, as 
noted above, the Exchange may already do pursuant to separate listing 
programs in the Rules).
    As also discussed above, the Exchange already lists P.M.-settled 
CBTX and MBTX options that expire on the last calendar day of the month 
and quarter; the proposed rule change merely permits these listings to 
occur under different programs within the Rules for consistency within 
the Exchange's Rules.\22\ Therefore, it is already possible for CBTX 
and MBTX options to be P.M.-settled and to expire on any day of the 
week (as the end of the month or the end of a quarter may fall on any 
day of the week). The Exchange also already allows CBTX and MBTX 
options to expire on Thursdays for normally Friday expiring options 
when the Exchange is not open for business on a respective Friday. 
Further, CBTX and MBTX options are available for FLEX trading pursuant 
to Rule 4.20, and thus, users may select expiration dates for these 
FLEX options for any day of the week and may select p.m.-settlement. 
The Exchange has observed no significant adverse economic impact on the 
futures, index, or underlying index component securities markets as a 
result of these listings.
---------------------------------------------------------------------------

    \22\ For example, it may be confusing to list Weeklys under the 
Nonstandard Expirations Program but monthlys under the Monthly 
program rather than the Nonstandard Expirations Program. As 
proposed, all index options the Exchange lists with expirations 
other than Expiration Fridays would be eligible for those 
expirations under the same programs.
---------------------------------------------------------------------------

    The Commission previously recognized that listing P.M.-settled 
index options with Weekly Expirations and Expiration Friday expirations 
(in addition to EOM Expirations (which would include expirations on the 
last day of calendar quarters)) was consistent with the Act.\23\ The 
Commission noted that expirations in those index options would ``offer 
additional investment options to investors and may be useful for their 
investment or hedging objectives. . . .'' \24\ The Exchange also notes 
it previously listed P.M.-settled broad-based index options with 
Weekly, EOM, and Expiration Friday expirations pursuant to pilot 
programs, so the Commission could monitor the impact of P.M.-settlement 
of cash-settled index derivatives on the underlying cash markets (while 
recognizing that these risks may have been mitigated given enhanced 
closing procedures in use in the primary equity markets); however, the 
Commission approved proposed rule changes to make those pilot programs 
permanent. The Commission noted that the data it reviewed in connection 
with the pilot demonstrated that these options ``benefitted investors 
and other market participants by providing more flexible trading and 
hedging opportunities while also having no disruptive impact on the 
market'' and were thus consistent with the Act.\25\ The proposed rule 
change is consistent with these findings, as it will benefit investors 
and other market participants that participate in the markets for 
additional index options in the same manner by providing them with more 
flexible trading and hedging opportunities.

reviewed in connection with the pilot programs).
---------------------------------------------------------------------------

    Further, the Exchange believes P.M.-settlement is appropriate for 
this CBTX and MBTX options because they trade within a complex where, 
in addition to the underlying components, there are multiple other 
highly correlated instruments that all hold Bitcoin available for 
hedging (e.g., options on the components, shares of other ETFs that 
hold Bitcoin, Bitcoin futures). This reduces the risk that listing 
these options would strain liquidity providers. Further, the size of 
the markets of the underlying components,\26\ the weighting of the 
components, and the high correlation of these components makes it 
unlikely the proposed rule change would materially impact the component 
markets, the index value, or the broader market.
---------------------------------------------------------------------------

    \26\ The assets under management of the index components range 
from $130 million to $48 billion as of April 15, 2025. Additionally, 
the narrow-based listing criteria pursuant to which these index 
options are listed impose various requirements on the component 
securities related to the market capitalization and liquidity, which 
further reduce the risk that the markets for the components would be 
impacted by additional derivatives. For example, pursuant to Rule 
4.10(b): (1) the market capitalization for the lowest-weighted 
component securities in the index that in the aggregate account for 
no more than 10% of the weight of the index must be at least $50 
million, and the market capitalization of all other components must 
be at least $75 million; (2) the trading volume in each component 
must be at least 1,000,000 shares for each of the last six months 
(from October 2024 through March 2025, the lowest monthly trading 
volume for a component was over 1.5 million shares), except that for 
each of the lowest-weighted component securities in the index that 
in the aggregate account for no more than 10% of the weight the 
index, the trading volume must be at least 500,000 shares for each 
of the last six months); and (3) no single component security may 
represent more than 25% of the weight of the index, and the five 
highest-weighted component securities in the index may not in the 
aggregate account for more than 50% (60% for an index consisting of 
fewer than 25 component securities) of the weight of the index.
---------------------------------------------------------------------------

    As is the case for options on broad-based indexes, the Exchange 
does not believe the listing of additional P.M.-settled CBTX and MBTX 
options (which are narrow-based index options) will have any 
significant economic impact (such as on market quality or volatility) 
on the component securities underlying the index surrounding the close 
as a result of expiring p.m.-settled options or impact market quality. 
This is based on the data provided to and reviewed by the Commission 
(and the Commission's own conclusions based on that review, as noted 
above) and due to the significant changes in closing procedures in the 
decades since index options moved to a.m.-settlement.\27\ The Exchange 
believes the potential for any such impact is not only no greater for 
narrow-based indexes than broad-based indexes, but is less likely for 
narrow-based indexes such as CBTX and MBTX, as the indexes underlying 
such options are by definition not representative of an entire market 
(as is the case for options on the S&P 500 Index). Therefore, any 
potential impact would be limited in scope (as noted above, the 
Commission found no material impact with respect to P.M.-settled broad-
based index options), unlike for a broad-based index, which would 
impact the market as a whole. Therefore, because, as noted above, the 
Commission found no material impact with respect to broad-based index 
options, the Exchange believes that it is reasonable that no material 
impact would occur with respect to CBTX and MBTX options for the 
reasons described above (including the high correlation of the 
component securities and the availability of multiple highly correlated 
instruments for hedging). The narrow scope of

[[Page 24185]]

narrow-based indexes aligns closer to the scope of equity options 
(which are P.M.-settled, such as the options overlying certain of the 
Bitcoin ETFs that comprise the index underlying CBTX and MBTX options).
---------------------------------------------------------------------------

    \27\ See id.
---------------------------------------------------------------------------

    Further, the index underlying CBTX and MBTX options satisfies the 
generic listing criteria in Rule 4.10(b). Upon approval of those 
listing criteria, the Commission noted that these generic standards 
were reasonably designed to ensure the protection of investors and the 
public interest and to ensure that the trading markets for the 
components were adequately capitalized and sufficiently liquid, and 
that no one component dominated the index, thus minimizing the 
potential for manipulation.\28\ This listing criteria includes the 
following:
---------------------------------------------------------------------------

    \28\ See Securities Exchange Act Release No. 34157 (June 3, 
1994), 59 FR 30062 (June 10, 1994) (SR-Amex-92-35, SR-CBOE-93-59, 
SR-NYSE-94-17, SR-PSE-94-07, and SR-Phlx-94-10). The Commission made 
substantially similar findings with respect to generic listing 
criteria for broad-based index options. See Securities Exchange Act 
Release No. 53266 (February 9, 2006), 71 FR 8321 (February 16, 2006) 
(SR-CBOE-2005-59) (the Commission noted that the listing criteria 
were ``designed to ensure that the markets for the index's component 
stocks are adequately capitalized and sufficiently liquid, and that 
no one stock dominates the index'' and thus ``minimize the potential 
for manipulating the underlying index'').
---------------------------------------------------------------------------

     each component security has a market capitalization of at 
least $75 million, except that for each of the lowest weighted 
component securities in the index that in the aggregate account for no 
more than 10% of the weight of the index, the market capitalization is 
at least $50 million;
     trading volume of each component security has been at 
least one million shares for each of the last six months, except that 
for each of the lowest weighted component securities in the index that 
in the aggregate account for no more than 10% of the weight of the 
index, trading volume has been at least 500,000 shares for each of the 
last six months;
     in a capitalization-weighted index or a modified 
capitalization-weighted index, the lesser of the five highest weighted 
component securities in the index or the highest weighted component 
securities in the index that in the aggregate represent at least 30% of 
the total number of component securities in the index each have had an 
average monthly trading volume of at least 2,000,000 shares over the 
past six months;
     no single component security represents more than 25% of 
the weight of the index, and the five highest weighted component 
securities in the index do not in the aggregate account for more than 
50% (60% for an index consisting of fewer than 25 component securities) 
of the weight of the index; and
     component securities that account for at least 90% of the 
weight of the index and at least 80% of the total number of component 
securities in the index satisfy the requirements of Rule 4.3 applicable 
to individual underlying securities.
    Therefore, by satisfying the generic listing criteria for narrow-
based index options, the index underlying CBTX and MBTX options is, 
like broad-based indexes, designed to minimize the potential for 
manipulation, further reducing any potential concerns associated with 
P.M.-settlement.
    In addition, the Exchange believes that the proposal to end trading 
at 4:00 p.m. on the last trading day for transactions in expiring P.M.-
settled CBTX and MBTX options will prevent continued trading on a 
product after the exercise settlement value has been fixed, thereby 
mitigating potential investor confusion and the potential for increased 
costs to investors as a result of potential pricing divergence at the 
end of the trading day.
    Finally, the Exchange believes the proposed rule change that 
Nonstandard Expiration Program series of CBTX and MBTX options will be 
aggregated with other options within those classes for purposes of 
position (and exercise) limits is designed to prevent fraudulent and 
manipulative acts and practices and to promote just and equitable 
principles of trade, and thus protect investors. This proposed 
aggregation is consistent with the treatment of positions for purposes 
of position (and exercise) limits for other classes that participate in 
the Nonstandard Expiration Program.\29\ Therefore, the current position 
and exercise limits that apply to CBTX and MBTX options will continue 
to apply, as the proposed additional expirations for these options 
would have no impact on the number of positions that may be held (or 
exercised) within a single account.
---------------------------------------------------------------------------

    \29\ See Rule 8.31(b).

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 the proposed rule change will impose any burden on 
intramarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act because P.M.-settled CBTX and 
MBTX options with Weekly and Expiration Friday expirations will be 
available to all market participants. By listing CBTX And MBTX options 
with these expirations (in addition to the monthly, quarterly, and 
standard Expiration Friday expirations (A.M.-settled) that are 
currently listed), the proposed rule change will provide all investors 
that participate in the markets for these index options available for 
trading on the Exchange with greater trading and hedging opportunities 
and flexibility to meet their investment and hedging needs, which are 
already available for broad-based index options. Further, the proposed 
change to make CBTX and MBTX options that are P.M.-settled and expire 
on the last business day of the month or quarter eligible for listing 
under different programs under the Rules will have any burden on 
competition, as this proposed rule change is intended to maintain 
consistency within the Rules and will result in the same series being 
listed. The proposed 4:00 p.m. closing time for expiring P.M.-settled 
CBTX and MBTX options on their expiration dates will apply equally to 
all market participants trading these options.
    The Exchange does not believe that the proposal to list P.M.-
settled CBTX and MBTX options with Weekly and Expiration Friday 
expirations will impose any burden on intermarket competition that is 
not necessary or appropriate in furtherance of the purposes of the Act 
because these options are proprietary Exchange products. The Exchange 
may currently list the same expirations for other index options, so the 
proposed rule change merely expands the availability of these 
expiration programs to additional products. Other exchanges offer 
similar expirations for index options as well as short-term options 
programs for certain equity options that expire each day of the week, 
at the end of the calendar month, at the end of the calendar quarter, 
and on Expiration Fridays \30\ and are welcome to similarly propose to 
list options on those index or equity products with similar 
expirations. To the extent that the addition of these expirations for 
CBTX and MBTX options makes the Exchange a more attractive marketplace 
to market participants at other exchanges, such

[[Page 24186]]

market participants are free to elect to become market participants on 
the Exchange.
---------------------------------------------------------------------------

    \30\ See, e.g., Nasdaq PHLX, LLC Options 4A, Section 12 
(permitting nonstandard expirations, including daily expirations for 
Nasdaq-100 index options and Nasdaq 100-Micro index options); and 
Nasdaq ISE, LLC Options 4, Section 5, Supplementary Material .03 
(permitting short-term options series with daily expirations for SPY 
and QQQ options).
---------------------------------------------------------------------------

    Additionally, CBTX and MBTX options with these expirations will 
trade in the same manner as other options with these expirations 
currently do.

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. Proceedings To Determine Whether To Approve or Disapprove SR-CBOE-
2025-004 as Modified by Amendment No. 1, and Grounds for Disapproval 
Under Consideration

    The Commission is instituting proceedings pursuant to Section 
19(b)(2)(B) of the Act \31\ to determine whether the proposed rule 
change, as modified by Amendment No. 1, should be approved or 
disapproved. Institution of such proceedings is appropriate at this 
time in view of the legal and policy issues raised by the proposed rule 
change, as modified by Amendment No. 1. Institution of proceedings does 
not indicate that the Commission has reached any conclusions with 
respect to any of the issues involved. Rather, as described below, the 
Commission seeks and encourages interested persons to provide comments 
on the proposed rule change, as modified by Amendment No. 1.
---------------------------------------------------------------------------

    \31\ 15 U.S.C. 78s(b)(2)(B).
---------------------------------------------------------------------------

    Pursuant to Section 19(b)(2)(B) of the Act,\32\ the Commission is 
providing notice of the grounds for disapproval under consideration. As 
described above, the Exchange has proposed to add P.M.-settled options 
on CBTX and MBTX with third Friday expirations, Weekly and EOM 
expirations, and quarterly index expirations. The Commission is 
instituting proceedings to allow for additional analysis of the 
proposal's consistency with Section 6(b)(5) of the Act,\33\ which 
requires, among other things, that the rules of a national securities 
exchange be designed to prevent fraudulent and manipulative acts and 
practices, to promote just and equitable principles of trade, to remove 
impediments to and protect the mechanism of a free and open market and 
a national market system, and, in general, to protect investors and the 
public interest.

    Under the Commission's Rules of Practice, the ``burden to 
demonstrate that a proposed rule change is consistent with the [Act] 
and the rules and regulations issued thereunder . . . is on the self-
regulatory organization that proposed the rule change.'' \34\ The 
description of a proposed rule change, its purpose and operation, its 
effect, and a legal analysis of its consistency with applicable 
requirements must all be sufficiently detailed and specific to support 
an affirmative Commission finding,\35\ and any failure of a self-
regulatory organization to provide this information may result in the 
Commission not having a sufficient basis to make an affirmative finding 
that a proposed rule change is consistent with the Act and the 
applicable rules and regulations.\36\ The Commission is instituting 
proceedings to allow for additional consideration and comment on the 
issues raised herein, including as to whether the proposal is 
consistent with the Act. In particular, the Commission asks commenters 
to address the potential market impacts of allowing the listing and 
trading of the proposed P.M.-settled options on CBTX and MBTX.

IV. Procedure: Request for Written Comments

    The Commission requests that interested persons provide written 
submissions of their views, data, and arguments with respect to the 
issues identified above, as well as any other concerns they may have 
with the proposed rule change, as modified by Amendment No. 1. In 
particular, the Commission invites the written views of interested 
persons concerning whether the proposed rule change, as modified by 
Amendment No. 1, is consistent with Section 6(b)(5) or any other 
provision of the Act, and the rules and regulations thereunder. 
Although there do not appear to be any issues relevant to approval or 
disapproval that would be facilitated by an oral presentation of views, 
data, and arguments, the Commission will consider, pursuant to Rule 
19b-4 under the Act,\37\ any request for an opportunity to make an oral 
presentation.\38\

Commission flexibility to determine what type of proceeding--either 
oral or notice and opportunity for written comments--is appropriate 
for consideration of a particular proposal by a self-regulatory 
organization. See Securities Acts Amendments of 1975, Senate Comm. 
on Banking, Housing & Urban Affairs, S. Rep. No. 75, 94th Cong., 1st 
Sess. 30 (1975).
