SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-105479; File No. SR-CBOE-2026-016]


Self-Regulatory Organizations; Cboe Exchange, Inc.; Notice of 
Filing of Amendment No. 1 and Order Instituting Proceedings To 
Determine Whether To Approve or Disapprove a Proposed Rule Change, as 
Modified by Amendment No. 1, To Amend Its Rules Relating to Designated 
Primary Market-Makers (``DPMs'') and DPM Appointments in Global Trading 
Hours and Curb Sessions

May 13, 2026.

I. Introduction

    On January 30, 2026, Cboe Exchange, Inc. (``Exchange'' or ``Cboe 
Options'') filed with the Securities and Exchange Commission 
(``Commission'' or ``SEC''), pursuant to Section 19(b)(1) of the 
Securities Exchange Act of 1934 (``Act'' or ``Exchange Act''),\1\ and 
Rule 19b-4 thereunder,\2\ a proposed rule change to modify rules 
pertaining to Designated Primary Market-Makers (``DPMs'') to: (1) 
clarify that the Exchange may appoint

[[Page 28706]]

DPMs to Global Trading Hours (``GTH'') and Curb Trading Hours 
(``Curb'') sessions and that DPMs may be the same across multiple 
trading sessions or different (or no DPM) for an option class in 
Regular Trading Hours (``RTH''), GTH, and/or Curb sessions; (2) provide 
that DPM obligations and participation entitlements will apply to GTH 
and Curb sessions; and (3) make certain administrative changes. The 
proposed rule change was published for comment in the Federal Register 
on February 13, 2026.\3\ On March 25, 2026, pursuant to Section 
19(b)(2) of the Exchange Act,\4\ the Commission designated a longer 
period within which to approve the proposed rule change, disapprove the 
proposed rule change, or institute proceedings to determine whether to 
disapprove the proposed rule change.\5\ The Commission received no 
comments regarding the proposed rule change. On April 13, 2026, the 
Exchange filed Amendment No. 1 to the proposed rule change, which 
replaced and superseded the original filing in its entirety. The 
Commission is publishing this Notice and Order to solicit comment on 
Amendment No. 1 in Sections II and III below, which sections are being 
published verbatim as filed by the Exchange, and to institute 
proceedings under Section 19(b)(2)(B) of the Exchange Act \6\ to 
determine whether to approve or disapprove the proposed rule change, as 
modified and superseded by Amendment No. 1.

II. Description of the Proposed Rule Change

    As described more fully in the Notice,\7\ the Exchange proposes to 
modify rules pertaining to Designated Primary Market-Makers (``DPMs'') 
to (1) clarify the Exchange may appoint DPMs to Global Trading Hours 
(``GTH'') and Curb Trading Hours (``Curb'') sessions and that DPMs may 
be the same across multiple trading sessions or different (or no DPM) 
for an option class in Regular Trading Hours (``RTH''), GTH, and/or 
Curb sessions; (2) provide that DPM obligations and participation 
entitlements will apply to GTH and Curb sessions; and (3) make certain 
administrative changes.\8\ The Exchange initially submitted this rule 
filing as SR-CBOE-2026-016 to the Securities and Exchange Commission 
(the ``Commission'') on January 30, 2026 (the ``Initial Rule Filing''). 
Amendment No. 1 supersedes the Initial Rule Filing and replaces it in 
its entirety. Amendment No. 1 provides additional support for the 
proposal by (1) detailing the Exchange's authority to review DPM 
compliance with quoting obligations and address occurrences of 
noncompliance, and (2) adding minor clarifications regarding quoting 
obligations. However, Amendment No. 1 makes no substantive changes to 
the proposal. The text of the proposed rule change is provided in 
Exhibit 5.

    The text of the proposed rule change is also available on the 
Commission's website (<a href="https://www.sec.gov/rules/sro.shtml">https://www.sec.gov/rules/sro.shtml</a>), the 
Exchange's website (<a href="https://www.cboe.com/us/options/regulation/rule_filings/bzx/">https://www.cboe.com/us/options/regulation/rule_filings/bzx/</a>), and at the principal office of the Exchange.

III. 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
    DPMs are Trading Permit Holders (``TPHs'') that are approved by the 
Exchange to function in appointed securities as a Market-Maker.\9\ The 
Exchange proposes to amend certain Cboe Rules regarding DPM 
appointments. Specifically, the Exchange proposes to (1) clarify the 
Exchange may appoint DPMs to GTH and Curb sessions and that DPM 
appointments for an option class may differ by trading session \10\ 
while acknowledging that a trading session may not have a DPM \11\; (2) 
provide that heightened DPM quoting obligations and participation 
entitlements apply during GTH and Curb sessions; and (3) make certain 
administrative changes.
---------------------------------------------------------------------------

    \9\ See Rule 1.1 (definition of DPM).
    \10\ The term ``trading session'' means the hours during which 
the Exchange is open for trading for Regular Trading Hours, Global 
Trading Hours or Curb Trading Hours (each of which may be referred 
to as a trading session), each as set forth in Rule 5.1. Unless 
otherwise specified in the Rules or the context otherwise indicates, 
all Rules apply in the same manner during each trading session. See 
Rule 1.1 (Definitions).
    \11\ See Rule 5.50(l), which states that the Exchange may 
designate a class for trading without a DPM.
---------------------------------------------------------------------------

    First, the Exchange proposes to amend Cboe Rules 1.1 and 3.53 to 
update requirements and administrative processes for DPMs to explicitly 
state that the Exchange may appoint DPMs for all trading sessions 
(i.e., RTH, GTH,\12\ and Curb \13\), and that DPMs may be the same or 
different across trading sessions. Pursuant to the definition of DPM in 
Cboe Rule 1.1 and the provisions of Cboe Rule 5.52(h), the Exchange may 
determine DPM appointments for classes (including that a DPM may not be 
appointed for a class). Pursuant to Cboe Rule 1.5, if Cboe Rules permit 
the Exchange to make a determination (including on a class-by-class 
basis), the Exchange may make that determination on a trading session-
by-trading session basis. Therefore, Cboe Rules permit the Exchange to 
determine DPM appointments for all trading sessions, and the Exchange 
may appoint the same DPM for all trading sessions or may appoint 
different DPMs on a trading session-by-trading session basis. The 
proposed rule change merely explicitly states this in Cboe Rules. The 
Exchange proposes to update the definition of DPM in Cboe Rule 1.1 to 
state that 1) the Exchange designates DPMs per trading session, 2) On-
Floor DPM is a term applicable to RTH sessions (as the floor operates 
only during RTH), 3) a DPM's request to function as an Off-Floor DPM is 
applicable to RTH sessions, and 4) DPMs that are appointed for a GTH or 
Curb session are considered Off-Floor DPMs within Cboe Rules (since 
those sessions are electronic only).
---------------------------------------------------------------------------

    \12\ Except under unusual conditions as may be determined by the 
Exchange or the Holiday hours set forth in Rule 5.1(d), Global 
Trading Hours are from 8:15 p.m. (previous day) to 9:25 a.m. on 
Monday through Friday. See Rule 5.1(c).
    \13\ Except under unusual conditions as may be determined by the 
Exchange, or the Holiday hours set forth in Rule 5.1(e), Curb 
Trading Hours are from 4:15 p.m. to 5:00 p.m. on Monday through 
Friday. See Rule 5.1(d).
---------------------------------------------------------------------------

    To further codify that the Exchange may appoint DPMs by trading 
session, the Exchange proposes to amend Cboe Rule 3.53, which 
establishes certain processes for DPMs, including selection and 
termination processes for DPMs. Specifically, the Exchange proposes to 
amend Cboe Rule 3.53(d) to state that the Exchange has the authority to 
specify the trading session(s) for a DPM appointment as a possible 
condition on

[[Page 28707]]

an approval. Furthermore, since it may be necessary to facilitate 
trading in a specified extended hours trading session without a DPM 
when a DPM appointment is terminated, the Exchange proposes to amend 
Cboe Rule 3.53(f) to confirm that a DPM may not be designated for a GTH 
or Curb session when the existing DPM for such session is terminated. 
This proposed change acknowledges and aligns with Cboe Rule 5.50(l), 
which provides that a class may be designated for trading without a DPM 
(during any or all trading sessions, as determined by the Exchange).
    By amending these Cboe Rules to explicitly state the Exchange may 
designate a DPM by trading session, the Exchange recognizes that a DPM 
appointed for a class in RTH may not intend to participate in GTH or 
Curb sessions. Consequently, the Exchange proposes to amend Cboe Rules 
to clarify the Exchange's authority to designate different DPMs for 
RTH, GTH, and/or Curb sessions. This addresses the possibility that a 
DPM for a class in one trading session may not want the DPM role in 
other trading sessions. The Exchange believes having the ability to 
appoint different DPMs for different trading sessions may help bolster 
market liquidity in each trading session in which the Exchange chooses 
to appoint a DPM as it will not impose a DPM appointment to a TPH in a 
trading session(s) during which it chooses not to operate. In other 
words, a DPM in RTH, for example, will not be obligated to assume the 
DPM role in another session only to maintain its DPM appointment in the 
session it wants. Also, a DPM will not be required to relinquish its 
DPM appointment in a class for one trading session because it does not 
operate as the DPM in another trading session for the option class.
    Second, the Exchange proposes to amend its Rules to address DPM 
participation entitlements and quoting obligations during GTH and Curb 
sessions. The Exchange proposes to amend Cboe Rule 5.54(a) to provide 
that the obligations of DPMs that currently apply during RTH will also 
apply during to GTH and Curb, and compliance with the heightened 
continuous quoting obligations will be measured across all trading 
sessions for which a DPM has an appointment. As the Exchange 
historically has appointed LMMs to GTH (and Curb) but not DPMs, Cboe 
Rule 5.54(a) limits application of a DPM's obligations to RTH. If the 
Exchange determines to appoint a DPM to GTH and/or Curb, the Exchange 
believes it is appropriate for these obligations in Cboe Rule 5.54(a), 
including the continuous quoting obligation in subparagraph (1), to 
apply to DPMs during those trading sessions in the same manner as they 
do during RTH when the DPM has an appointment during those trading 
sessions. With respect to how a DPM's compliance with continuous 
quoting obligations is measured, the proposed rule change amends Cboe 
Rule 5.54(a)(1) to provide that this will occur across trading sessions 
for which the DPM has an appointment.
    The Exchange notes this is consistent with existing Cboe EDGX 
Exchange, Inc. (``EDGX'') Rules regarding DPMs. Specifically, pursuant 
to EDGX Rule 22.3(a), if a Market Maker selects an appointment in an 
option class, that appointment applies during both GTH and RTH and 
thus, the Market-Maker would have an appointment to make markets in the 
option class during both GTH and RTH on EDGX.\14\ Similarly, EDGX Rule 
22.2(e) provides that a Market-Maker may request the Exchange appoint 
it as DPM to a class for all trading sessions. As EDGX Rules do not 
contain a heightened continuous quoting obligation for DPMs as the 
Exchange's Rules do,\15\ the only continuous quoting obligation to 
which DPMs are subject is the standard obligation applicable to all 
Market-Makers.\16\ EDGX Rule 22.6(d) explicitly provides that Market-
Maker continuous quoting obligations (and thus DPM continuous quoting 
obligations) apply to the class for an entire trading day, including 
both trading sessions of RTH and GTH (there is no Curb session in the 
EDGX Rules). Consequently, since the Market-Maker continuous quoting 
obligation set forth in EDGX Rule 22.6(d) is the continuous quoting 
obligation for DPMs on EDGX and is measured across all trading 
sessions, and since EDGX Rules state that DPM appointments apply to all 
trading sessions for a class, the continuous quoting obligations 
applicable to a DPM on EDGX apply across all trading sessions. This 
approach is also currently used for Market-Maker obligations in 
extended trading hour sessions.\17\
---------------------------------------------------------------------------

    \14\ See also Securities Exchange Act Release No. 34-85797; (May 
7, 2019), 84 FR 20920 (May 13, 2019) (SR-CboeEDGX-2019-027).
    \15\ See Cboe Rule 5.54(a) which requires that a DPM provide 
continuous electronic quotes 90% of the time as applicable.
    \16\ See EDGX Rule 22.6(d) requires that a Market-Maker enter 
continuous bids and offers 60% of the time as applicable.
    \17\ See Rule 5.52(d)(2)(E), which states that Market-Maker 
obligations will apply across trading sessions and that if a Market-
Maker has an appointment in a class that is open for trading during 
multiple trading sessions, the Exchange will determine a Market-
Maker's compliance with the continuous electronic quoting 
requirement across the trading day.
---------------------------------------------------------------------------

    Although measuring a DPM's continuous quoting obligation for the 
entire trading day will increase the quoting requirement for the DPM 
because of the increase of trading time for which quotes must be 
provided, the DPM can meet the increased obligation through activity in 
RTH, GTH, and Curb.\18\ Since Cboe Rule 5.54(a) provides that DPM 
obligations require continuous quoting in a DPM's appointed classes, 
the Exchange calculates DPM compliance with quoting obligations across 
all of a DPM's option classes in totality rather than on a class-by-
class basis. To illustrate how the proposed rule change will apply the 
quoting obligation across trading sessions, when applicable, the 
following example assumes that a DPM is appointed to 10 classes, nine 
of which are equity option classes that trade in RTH only and the 
remaining option class is an index option that trades in RTH, GTH, and 
Curb. Each option class has 100 series. For the nine equity option 
classes, each one trades for 405 minutes (24,300 seconds) in RTH in a 
trading day. To include this trading time in the calculation to 
determine compliance, the RTH time is multiplied by the number of 
series (in this case, 100), resulting in 40,500 minutes (2,430,000 
seconds) per each class. The index option will trade for 790 minutes 
(47,400 seconds) in GTH, 45 minutes (2700 seconds) in Curb, and 405 
minutes (24,300 seconds) in RTH, for a total of 1,240 minutes (74,400 
seconds). To include this trading time in the calculation to determine 
compliance, the total time is multiplied by 100 series, resulting in 
124,000 minutes (7,440,000 seconds). To determine compliance with the 
90% continuous quoting obligation in Cboe Rule 5.54, the total trading 
times will be combined, resulting in 29,310,000 seconds ((2,430,000 
seconds x 9 classes) + 7,440,000 seconds) and multiplied by 90% to 
equal 26,379,000 seconds that the DPM must provide continuous quoting. 
To meet this quoting obligation, the DPM could quote 100% of the equity 
classes (21,870,000 seconds) and would be required to quote the index 
class for 4,509,000 seconds (which is 67% of all trading sessions) to 
meet the overall 90% requirement obligation. Alternatively, if the DPM 
only quoted 100% of the index class in GTH and Curb (5,010,000 seconds 
combined), the DPM would still be required to quote the equity option 
classes for 21,369,000 (which is 97.70% of the RTH trading session for 
equities) to meet the 90% requirement overall.

[[Page 28708]]

Additionally, if the DPM quoted 100% of the index class in GTH, RTH, 
and Curb (7,440,000 seconds total), the DPM would still be required to 
quote the equity option classes for 18,939,000 (which is 72.84% of the 
RTH trading session for equities) to meet the 90% requirement overall.
---------------------------------------------------------------------------

    \18\ See note 14 supra.
---------------------------------------------------------------------------

    As Cboe Rule 5.54 already provides that DPM quoting obligations 
apply collectively to all of a DPM's appointed classes,\19\ the 
Exchange believes that applying the continuous quoting requirements for 
DPMs collectively across all classes and trading sessions is a fair and 
efficient way for the Exchange and market participants to evaluate 
compliance with the continuous quoting obligation. Applying the 
continuous quoting requirements collectively across all classes and 
trading sessions rather than on a class-by-class and trading session-
by-trading session basis is beneficial to DPMs by providing some 
flexibility to choose which series in their appointed classes they will 
continuously quote--increasing the continuous quoting in the series of 
one class while allowing for a decrease in the continuous quoting in 
the series of another class. This flexibility, however, does not 
diminish the DPM's obligation to continuously quote in a significant 
percentage of series for a significant part of the trading day. This 
flexibility is especially important for classes that have relatively 
few series and may prevent a DPM from reaching the continuous quoting 
obligation when failing to quote 90% of the trading day in more than 
one series in an appointed class. The Exchange believes that the 
proposed rule change will not diminish, and may in fact increase, 
market making activity on the Exchange, by applying continuous quoting 
obligations in a reasonable manner, which is in alignment with rules 
already in place on another options exchange. The Exchange does not 
anticipate that DPM quoting will routinely decrease and notes that, as 
illustrated in the examples above, that DPM obligation is expected to 
remain above the standard Market-Maker obligation requiring continuous 
quoting during 60% of the trading day. By requiring that a DPM meet its 
continuous quoting obligations across all trading sessions in which it 
is appointed as the DPM (and collectively across classes, as is the 
case today), a DPM might meet its obligations on a given day even if it 
falls below obligation requirements in one trading session if the DPM 
surpasses obligations requirements in another session because the total 
activity across trading sessions for a DPM will be used to determine 
compliance with continuous quoting obligation requirements. 
Additionally, this approach is intended to help reduce the rigidity of 
quoting requirements for a DPM of multiple sessions if trading activity 
is less in one of the sessions. The Exchange believes that applying the 
existing DPM obligations for RTH trading to GTH and Curb trading 
sessions will promote active markets in these extended trading hours 
sessions. Furthermore, applying such obligations across multiple 
trading sessions if a DPM is appointed to more than one trading session 
for a class will help foster liquid markets while providing flexibility 
to DPMs to meet their obligations. The Exchange does not believe that 
determining compliance with quotation obligations across trading 
sessions will result in less liquidity in RTH. To the contrary, the 
Exchange anticipates that DPMs may utilize activity in RTH to meet any 
shortfalls in 90% quoting obligations that a DPM may experience in GTH 
or Curb. The Exchange has observed that trading characteristics during 
RTH are typically different than those during extended hours trading 
sessions in that extended sessions have lower trading levels, reduced 
liquidity, and fewer participants. Therefore, the Exchange believes it 
is appropriate to extend to DPMs this flexibility across trading 
sessions to meet continuous quoting requirements. The Exchange notes 
that DPMs must still satisfy obligations set forth in Rule 5.54 in all 
trading sessions, including to make competitive markets. Further, to 
the extent the Exchange applies the DPM participation entitlement or 
small order entitlement during a trading session, the DPM must be 
quoting at the top of the Book \20\ (i.e., has a quote at the highest 
bid or lowest offer) to receive such entitlement, as set forth in Rule 
5.32(a)(2)(B) and (C). Therefore, the Exchange does not believe DPMs 
will be less likely to quote at the top of the Book if the DPM is a DPM 
across multiple sessions.
---------------------------------------------------------------------------

    \19\ See Rule 5.54(a)(2), which states that compliance with DPM 
quoting obligation applies to all of a DPM's appointed classes 
collectively
    \20\ See Rule 1(a), which defines ``Book'' as the electronic 
book of simple orders and quotes maintained by the System.
---------------------------------------------------------------------------

    The Exchange also proposes to amend Cboe Rule 5.32 to permit the 
Exchange to apply the DPM participation entitlement during GTH and 
Curb. Cboe Rule 5.32(a) provides the Exchange with authority to 
determine which allocation algorithm and priority overlays, including 
the DPM participation entitlement, will apply on a class-by-class 
basis. As noted above, pursuant to Cboe Rule 1.5, if Cboe Rules permit 
the Exchange to make a determination (including on a class-by-class 
basis), the Exchange may make that determination on a trading session-
by-trading session basis. Therefore, Cboe Rules currently permit the 
Exchange to determine what allocation algorithm and priority overlays 
it may apply to RTH, GTH, and Curb. However, Cboe Rules do not permit 
the DPM participation entitlement to apply during GTH and Curb. As the 
Exchange may determine to appoint DPMs during GTH and Curb going 
forward, the Exchange proposes to allow DPM participation entitlements 
to apply during those trading sessions in the same manner it can during 
RTH. Given that a DPM will be subject to heightened continuous quoting 
obligations during GTH and Curb, as discussed above, the Exchange 
proposes to permit it to apply the DPM participation entitlement as a 
priority overlay during those trading sessions, as it is able to do 
during RTH. Specifically, the Exchange proposes to amend Cboe Rule 
5.32(a)(2)(B)(iv) to state that DPM participation entitlements may 
apply during GTH and Curb sessions. Pursuant to Cboe Rule 
5.32(a)(2)(B), the Exchange may apply one or more of the participation 
entitlements provided in the rule,\21\ and the proposed addition to 
Cboe Rule 5.32(a)(2)(B)(iv) provides that the Exchange may apply 
participation entitlements in the same manner during GTH and Curb. The 
Exchange believes that having the ability to apply the existing 
participation entitlements for RTH to GTH and Curb sessions will 
appropriately incentivize DPM participation in the extended trading 
hours sessions for which they are appointed to help provide market 
liquidity during such sessions. Additionally, the Exchange does not 
believe that applying the participation entitlements across trading 
sessions will result in a reduction in DPM quoting activity during the 
RTH session because liquidity and demand are expected to remain highest 
during RTH. As noted above, DPMs will only receive an entitlement 
during a trading session if they are quoting at the best price.
---------------------------------------------------------------------------

    \21\ See Rule 5.32(a)(2)(B), which states that if a DPM has a 
quote at the highest bid or lowest offer, it will receive the 
greater of (i) the number of contracts it would receive pursuant to 
the applicable base allocation algorithm and (ii) 50% of the 
contracts if there is one other non-Priority Customer, 40% of the 
contracts if there are two non-Priority Customers, or 30% of the 
contracts if there are three or more non-Priority Customers with 
orders or quotes on the Book at that price.
---------------------------------------------------------------------------

    As is the case today, the Exchange will monitor DPM activity to 
verify compliance with quoting obligations

[[Page 28709]]

and will determine a DPM's compliance with the 90% quoting obligation 
contained in Rule 5.54(a)(1), which applies to all of a DPM's classes 
collectively, on a monthly basis.\22\ Additionally, the Exchange may 
conduct a review of a DPM's performance at any time.\23\ The Exchange 
currently conducts regular reviews of DPM's performance, which reviews 
the Exchange would expand to include GTH and Curb. The Exchange may 
take action against a DPM that fails to comply with any of the 
requirements under Rules 3.53, 3.54, or 5.54, and such action may 
include terminating, placing conditions upon, or otherwise limiting a 
TPH organization's DPM approval.\24\ If the Exchange determines to 
limit a TPH's approval to act as a DPM, the Exchange may, in addition 
to other actions, limit or withdraw the TPH organization's DPM 
participation entitlement provided for under Rule 5.32, withdraw the 
right of the TPH organization to act in the capacity of a DPM in a 
particular security or securities which have been allocated to the TPH 
organization, and/or require the relocation of the TPH organization's 
DPM operation on the Exchange's trading floor.\25\ Furthermore, 
pursuant to Rule 13.1(g)(9), the Exchange has the authority to impose 
fines on a DPM for failure to meet continuous quoting obligations. The 
Exchange intends to apply existing monitoring practices to DPM activity 
in GTH and Curb sessions and, if warranted, impose penalties or issue 
fines to DPMs that do not fulfill their obligations.

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

    Finally, as an administrative change, the Exchange proposes to 
amend Cboe Rule 5.50(b), which establishes cutoff times by trading 
sessions for submission of Market-Maker appointment requests to remove 
specific time requirements from the Rules. Although such cutoff times 
were previously added to Cboe Rules, relocation of these time 
requirements will enhance the Exchange's ability to react to future 
advancements in technology that may allow the Exchange to provide more 
time to Market-Makers to submit appointment requests. Consequently, the 
Exchange believes this type of technical detail should be maintained in 
the Exchange's technical specifications rather than Cboe Rules and 
therefore proposes to replace these specific cutoff times currently 
provided in Cboe Rules with a statement that such deadlines will be 
specified in the Exchange's technical specifications.\26\ This change 
aligns with Cboe Rule 1.5(a) which states that the Exchange will 
announce determinations to TPHs via various means of communication, 
including specifications. By relocating cutoff times from the Rules to 
technical specifications documentations, the Exchange will have the 
ability to adjust times more quickly in the future. Notice of these 
cutoff times and any subsequent changes to them will be provided via 
technical specification documentation as required by Cboe Rule 1.5(a). 
In the event that technology advances allow the Exchange to process 
requests with less notice, the Exchange may modify the cutoff times in 
the technical specifications and provide Market-Makers more time to 
meet deadlines. Furthermore, removing the specific time requirements in 
Cboe Rule 5.50 will align the rule's structure to Cboe Rule 5.54(a)(6) 
which provides that the Exchange may determine time requirements but 
does not include the details of such time requirements within Cboe 
Rules. The Exchange believes this proposed change will therefore 
provide greater consistency within Cboe Rules.
---------------------------------------------------------------------------

    \26\ See Rule 1.5(a), which states that the Exchange will 
announce determinations to TPHs via various means of communication, 
including specifications.
---------------------------------------------------------------------------

    As an additional administrative change, the Exchange also proposes 
to amend Cboe Rule 5.50(l) to return language to the provision that was 
inadvertently removed from the Rules in a rule change connected to the 
System migration that took place in 2019.\27\ The proposed rule change 
merely adds back to the rule language that states that if the Exchange 
determines to list SPX or VIX on a group basis, it will have the 
authority to change the eligible categories of Market-Maker 
participants for each group.
---------------------------------------------------------------------------

    \27\ See Securities Exchange Act Release No. 34-87024 (September 
19, 2019), 84 FR 50545 (September 25, 2019) (SR-CBOE-2019-059).
---------------------------------------------------------------------------

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.\28\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \29\ 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) \30\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.

    In particular, the Exchange believes the proposed rule change to 
clarify in Cboe Rules that the Exchange may appoint DPMs to all trading 
sessions and on a trading session-by-trading session basis will remove 
impediments to and perfect the mechanism of a free and open market and 
protect investors, as such changes add transparency and clarity to Cboe 
Rules. In explicitly stating that DPM appointment designations may 
apply to one or multiple trading session(s), the Exchange recognizes 
that not all DPMs may intend to trade in all available trading sessions 
for an option class, and designation of different DPMs for a class by 
trading session may be appropriate to help provide market liquidity. 
The Exchange may designate a DPM for RTH and another for GTH or Curb 
based on DPM expressed interest in specific trading session(s), or, as 
indicated in Cboe Rule 5.50(l), the Exchange may list for trading a 
class without a DPM during a trading session. As noted above, this 
flexibility is already permitted under Cboe Rules. The flexibility to 
designate different DPMs provides the Exchange with the ability to 
appoint dedicated liquidity providers in all trading sessions to make 
active markets, which ultimately benefits investors.
    Furthermore, the Exchange believes the proposed rule change to 
apply DPM participation entitlements and obligations to GTH and Curb 
sessions as well as measuring compliance with the heightened continuous 
quoting obligations across trading sessions for DPMs with appointments 
for more than one trading session in a class will promote just and 
equitable principles of trade, 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. The proposed 
rule change will ultimately apply the same obligations to DPMs during 
GTH and Curb as are currently applied to DPMs during RTH. Additionally, 
the proposed rule change

[[Page 28710]]

will provide the Exchange with the same flexibility to apply the DPM 
participation entitlement during GTH and Curb in the same manner it is 
applied during RTH. The Exchange believes being able to apply the DPM 
participation entitlement during GTH and Curb may help incentivize 
Market-Maker participation in GTH and Curb sessions, balanced with the 
heightened continuous quoting obligations that will apply during those 
trading sessions.
    While the proposed rule change increases the total time a DPM must 
quote if it is appointed to GTH and/or Curb, this increase is de 
minimis given that a DPM's compliance with its continuous quoting 
obligation is based on all classes in which it has an appointment in 
the aggregate across trading sessions. A Market-Maker may choose to 
express interest in becoming a DPM during GTH and/or Curb. The Exchange 
believes that the slight additional burden of extending the continuous 
quoting obligation to the GTH and Curb trading sessions for DPMs' 
appointments in those trading sessions is outweighed by the benefits to 
investors that may result from that liquidity. The proposed rule change 
also continues to maintain a balance of DPM benefits and obligations, 
as the continuous quoting obligation and DPM participation entitlement 
that will apply during GTH and Curb are the same as those that apply 
today during RTH. Ultimately, the proposed rule change is intended to 
facilitate DPM involvement in GTH and Curb sessions and is intended to 
facilitate tighter spreads, increase trading opportunities, and overall 
enhanced market quality to the benefit of all market participants. As 
discussed above, measuring compliance with DPM continuous quoting 
obligations across trading sessions is consistent with current EDGX 
Rules.
    The Exchange notes if a DPM in a class during RTH does not seek to 
become the DPM in that class during GTH or Curb, this proposed rule 
change has no impact on that DPM's obligations, as the proposed change 
would only require additional quoting time for DPMs appointed to a 
class in multiple trading sessions. If a DPM in a class during RTH 
wants to be DPM in that class during other trading sessions, and the 
Exchange makes such appointment, the Exchange believes it is 
appropriate for that DPM to be subject to the same obligations during 
those additional trading sessions it is during RTH.
    Last, the Exchange believes that the largely administrative changes 
proposed for Cboe Rule 5.50 that would 1) remove specific time 
requirements from the rules and 2) return inadvertently deleted rule 
text are intended to remove impediments to and perfect the mechanism of 
a free and open market and a national market system and protect 
investors consistent with the Act. By moving Market-Maker application 
cutoff times from the rules to the Exchange's technical specification 
documentation, the Exchange will have the flexibility to change times 
in response to technology advances or future changes in trading times. 
By returning language inadvertently deleted regarding the Exchange's 
authority to change the eligible categories of Market-Maker 
participants for each group, the proposed change clarifies the manner 
in which the Exchange may function.

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. The proposed rule change to 
clarify the Exchange's ability to appoint DPMs to all trading sessions 
and on a trading session-by-trading session basis explicitly state what 
is permissible today under current Rules, as discussed above. These 
Rules will continue to apply in the same manner to all TPHs. The 
proposed rule change to apply DPM quoting obligations to GTH and Curb 
(and measure compliance with the continuous quoting obligation across 
trading sessions) and permit the Exchange to apply the DPM 
participation entitlement in GTH and Curb, will apply equally to all 
DPMs (and in the same manner as they do today to DPMs during RTH). 
While the proposed rule change increases the total time a DPM must 
quote if it is appointed to GTH and/or Curb, this increase is de 
minimis given that a DPM's compliance with its continuous quoting 
obligation is based on all classes in which it has an appointment in 
the aggregate across trading sessions. A Market-Maker may choose to 
express interest in becoming a DPM during GTH and/or Curb. As noted 
above, if a DPM in a class during RTH does not want to be DPM (or is 
not appointed as DPM) in that class during GTH or Curb, this proposed 
rule change has no impact on the DPM. The Exchange believes that the 
slight additional burden of extending the continuous quoting obligation 
to the GTH and Curb trading sessions for DPMs' appointments in those 
trading sessions is outweighed by the benefits to investors that may 
result from that liquidity. The proposed rule change also continues to 
maintain a balance of DPM benefits and obligations, as the continuous 
quoting obligation and DPM participation entitlement that will apply 
during GTH and Curb are the same as those that apply today during RTH. 
Additionally, the proposed changes to move time requirements to 
technical specification documents and add back inadvertently removed 
content are not for competitive purposes and are generally 
administrative changes to support market function. The Exchange does 
not believe the proposed rule change will impose any burden on 
intermarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act, as the proposed rule changes 
apply only to DPMs at the Exchange.

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 written comments on the 
proposed rule change.

IV. Proceedings To Determine Whether To Approve or Disapprove SR-CBOE-
2026-016, 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 Exchange Act \31\ to determine whether the proposed 
rule change, as modified by Amendment No. 1 (``Amended Proposal''), 
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. 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 Amended Proposal, to inform the Commission's analysis of whether 
to approve or disapprove the Amended Proposal.
---------------------------------------------------------------------------

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

    Pursuant to Section 19(b)(2)(B) of the Exchange Act,\32\ the 
Commission is providing notice of the grounds for disapproval under 
consideration. The Commission is instituting proceedings to allow for 
additional analysis of, and input from commenters with respect to,

[[Page 28711]]

the consistency of the Amended Proposal 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, promote just and equitable principles 
of trade, protect investors and the public interest; and not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.
---------------------------------------------------------------------------

    \32\ Id.
    \33\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Commission asks that commenters address the sufficiency of the 
Exchange's statements in support of the Amended Proposal, in addition 
to any other comments they may wish to submit about the proposal. In 
particular, under the Amended Proposal, the Exchange could appoint a 
DPM (or not appoint any DPM) in a class for all trading sessions as 
well as on a trading-session-by-trading-session basis.\34\ The Exchange 
would apply during GTH and Curb sessions the DPM obligations that 
currently apply during RTH, and the Exchange would measure compliance 
with DPMs' continuous quoting requirement across all trading sessions 
(and classes), in the aggregate, for which the DPM is appointed.\35\ In 
addition, the Exchange could apply priority overlays, as set forth in 
Rule 5.32(a)(2), to a DPM during any trading session for which the DPM 
is appointed.\36\ The Commission seeks comment on whether the Amended 
Proposal includes sufficient analysis of these proposed changes to 
support a conclusion that it is consistent with the requirements of 
Section 6(b)(5) of the Act.\37\
---------------------------------------------------------------------------

    \34\ See proposed Rules 1.1 and 3.53. The proposal also would 
allow the Exchange to permit trading to occur in a GTH or Curb 
session when there is no DPM for such session(s) due to resignation, 
termination or otherwise. See proposed Rule 3.53(f).
    \35\ See proposed Rule 5.54; see also supra Section III.
    \36\ See proposed Rule 5.32(a)(2); see also supra Section III.

V. Solicitation of Comments

    The Commission requests that interested persons provide written 
submissions of their data, views, and arguments with respect to the 
issues identified above, as well as any other concerns they may have 
with the proposal. In particular, the Commission invites the written 
views of interested persons concerning whether the proposed rule change 
is consistent with 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 data, 
views, and arguments, the Commission will consider, pursuant to Rule 
19b-4 under the Act,\38\ any request for an opportunity to make an oral 
presentation.\39\
---------------------------------------------------------------------------

    \38\ 17 CFR 240.19b-4.
    \39\ Section 19(b)(2) of the Act, as amended by the Securities 
Acts Amendments of 1975, Public Law 94-29 (June 4, 1975), grants to 
the 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).
