[Release No. 34-105569; File No. SR-CBOE-2025-079]


Self-Regulatory Organizations; Cboe Exchange, Inc.; Order 
Approving a Proposed Rule Change, as Modified by Amendment No. 1, To 
Allow for Extended Trading of Multi-Listed Equity Options

May 28, 2026.

I. Introduction

    On September 30, 2025, Cboe Exchange, Inc. (``Exchange'' or 
``Cboe'') filed with the Securities and Exchange Commission 
(``Commission''), pursuant to Section 19(b)(1) of the Securities 
Exchange Act of 1934 (``Act'') \1\ and Rule 19b-4 thereunder,\2\ a 
proposed rule change to allow for extended trading sessions of multi-
listed equity options that meet certain eligibility criteria. The 
proposed rule change was published for comment in the Federal Register 
on October 3, 2025.\3\ On November 3, 2025, pursuant to Section 
19(b)(2) of the 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\ On December 23, 2025, the 
Commission instituted proceedings under Section 19(b)(2)(B) of the Act 
to determine whether to approve or disapprove the proposed rule 
change.\6\ On March 23, 2026, pursuant to Section 19(b)(2) of the 
Act,\7\ the Commission designated a longer period within which to 
approve or disapprove the proposed rule change.\8\ On April 2, 2026, 
the Exchange filed Amendment No. 1 to the proposed rule change, which 
superseded the proposed rule change as originally filed and replaced it 
in its entirety.\9\ The proposed rule change, as modified by Amendment 
No. 1, was published for comment in the Federal Register on April 9, 
2026.\10\ The Commission received comments on the proposed rule 
change.\11\ This order approves the proposed rule change, as modified 
by Amendment No. 1.

addition, Amendment No. 1 revises the proposal such that it: (1) 
classifies the proposed extended afternoon session of 4:00-4:15 p.m. 
as a ``Curb'' session (instead of as a ``GTH'' session as initially 
proposed), and makes related rule text changes regarding series 
eligibility; (2) sets forth a selection and removal process for the 
equity options that may be traded on the Exchange during the 
proposed extended trading sessions; (3) describes when the Exchange

order routing processes to the proposed extended morning session; 
and (6) updates the Exchange's Global Trading Hours and Curb Trading 
Hours Disclosure.

rule change are available on the Commission's website at: <a href="https://www.sec.gov/rules-regulations/public-comments/sr-cboe-2025-079">https://www.sec.gov/rules-regulations/public-comments/sr-cboe-2025-079</a>.
---------------------------------------------------------------------------

II. Description of the Proposed Rule Change, as Modified by Amendment 
No. 1 <SUP>12</SUP>
---------------------------------------------------------------------------

    \12\ The Exchange sets forth additional detail and justification 
regarding the proposal in Amendment No. 1. See supra note 10. 
Capitalized terms not defined herein are defined in the Exchange's 
rules.
---------------------------------------------------------------------------

    Currently, the Exchange offers three trading sessions: (i) Regular 
Trading Hours (``RTH''); \13\ (ii) Curb Trading Hours (``Curb''); \14\ 
and (iii) Global Trading Hours (``GTH'').\15\ Multi-listed equity 
options currently may trade on the Exchange only during RTH, from 9:30 
a.m. through 4:00 p.m.,\16\ except equity options overlying certain 
designated Exchange Traded Funds (``ETFs''), Exchange Traded Notes 
(``ETNs''), Index Portfolio Shares, Index Portfolio Receipts, and Trust 
Issued Receipts (collectively herein, ``ETP options'') are eligible to 
trade until 4:15 p.m. as part of RTH.\17\ The Exchange's exclusively-
listed index options, by contrast, currently may trade during GTH and 
Curb, in addition to during RTH.\18\
---------------------------------------------------------------------------

    \13\ RTH occurs from 9:30 a.m. to 4:00 p.m. or 4:15 p.m., 
depending on the specific security, Monday through Friday. See Rule 
5.1(b)(1). All times referenced are Eastern Time, unless otherwise 
specifically noted.
    \14\ The current Curb session occurs from 4:15 p.m.to 5:00 p.m., 
Monday through Friday. See Rule 5.1(d).
    \15\ The current GTH session occurs from 8:15 p.m. to 9:25 a.m. 
the next day, Monday through Friday. See Rule 5.1(c).
    \16\ See Amendment No. 1, supra note 10, at 18011.
    \17\ See Rule 5.1(b)(1).
    \18\ See Rule 5.1(c)-(d). Currently, options on the S&P 500 
Index, CBOE Volatility Index, Cboe Mini SPX Index Options, Russell 
2000 Index, Mini-Russell 2000 Index, and Cboe Magnificent 10 Index 
are approved for trading during GTH and Curb. See id.
---------------------------------------------------------------------------

    As discussed more fully in Amendment No. 1, the Exchange proposes 
to amend Rule 5.1(c) to

[[Page 33006]]

provide for extended trading sessions for multi-listed equity options 
that meet certain eligibility criteria, as well as for FLEX options 
overlying the same equity.\19\ The Exchange would permit trading Monday 
through Friday in designated equity options before and after RTH.\20\ 
The proposed extended morning trading session, which the Exchange would 
classify as a GTH session, would occur from 7:30 a.m. to 9:25 a.m.\21\ 
The proposed extended afternoon session, which the Exchange would 
classify as a Curb session, would occur immediately after RTH for 
equity options (that are not ETP options that already trade until 4:15 
p.m. as part of RTH), from 4:00 p.m. to 4:15 p.m.\22\ The Exchange 
states that equity trading already occurs outside of regular market 
hours on equity exchanges, but because equity option trading hours have 
not changed, investors are unable to access the options markets during 
the extended trading hours when equities may trade, which limits 
investors' ability to hedge equity transactions with options or utilize 
options for other investment purposes or strategies.\23\ The Exchange 
also believes that the proposed extended trading sessions will make 
equity options trading more accessible to investors in other countries 
and to U.S. investors who wish to trade options in expanded trading 
sessions alongside the underlying equities.\24\
---------------------------------------------------------------------------

    \19\ See proposed Rule 5.1(c).
    \20\ See id.
    \21\ See id. The Exchange proposes to add references to equity 
options and Rule 4.5 (Series of Options Contracts Open for Trading) 
to current Rule 5.1(c)(2) in order to facilitate the trading of any 
series in eligible equity option classes that trade during the 
proposed GTH session. Furthermore, the Exchange proposes a technical 
change to renumber current Rules 5.1(c)(2), (3), and (4) as Rules 
5.1(c)(3), (4), and (5), respectively, because, as further explained 
below, the Exchange proposes to add a new Rule 5.1(c)(2).
    \22\ See proposed Rule 5.1(d). The Exchange also proposes to add 
references to equity options and Rule 4.5 to current Rule 5.1(d)(2) 
in order to facilitate the trading of any series in eligible equity 
option classes that trade during the proposed Curb session. 
Furthermore, the Exchange proposes a technical change to renumber 
current Rules 5.1(d)(2), (3), and (4) as Rules 5.1(d)(3), (4), and 
(5), respectively, because, as further explained below, the Exchange 
proposes to add a new Rule 5.1(d)(2).
    \23\ See Amendment No. 1, supra note 10, at 18012.
    \24\ See id. The Exchange states that, whereas certain 
processing aspects of GTH and Curb for equity options require 
explicit additions to the Exchange's rules, other GTH and Curb 
trading rules as currently stated would apply to equity options 
designated for trading in the proposed extended sessions. These 
rules cover, among other things, (i) electronic-only trading in GTH 
and Curb sessions, (ii) participation requirements, (iii) obvious 
errors, (iv) auction functionality, (v) risk controls, (vi) 
unavailability of market orders, (vii) market maker obligations, and 
(viii) utilization of existing series listing criteria. See 
Amendment No. 1, supra note 10, at 18017.
---------------------------------------------------------------------------

    The Exchange proposes eligibility criteria that must be satisfied 
by each class of equity options made available for trading during the 
proposed extended trading sessions, as well as a cap on the total 
number of eligible classes that may be made available. Specifically, 
under proposed Rules 5.1(c)(2) and 5.1(d)(2),\25\ the Exchange may 
designate for trading during the proposed GTH and Curb sessions up to 
100 actively-traded, equity option classes that meet the following 
minimum criteria for the preceding six calendar months: (i) the option 
has an average daily volume of 150,000 contracts, (ii) the equity 
security underlying the option has a $50 billion market capitalization, 
and (iii) the equity security underlying the option has an average 
daily trading volume of 10 million shares.\26\ The Exchange may also 
designate for trading during the proposed GTH and Curb sessions any 
equity option that is traded on another exchange during GTH or any 
other trading session that is not RTH; any such equity option would not 
be subject to the 100-class limit.\27\ Moreover, if the Exchange 
designates a class of equity options as eligible for trading during the 
proposed GTH and Curb sessions, FLEX options with the same underlying 
equity security also would be deemed eligible for the proposed extended 
trading sessions.\28\
---------------------------------------------------------------------------

    \25\ Proposed Rule 5.1(c)(2) sets forth the eligibility criteria 
for equity options to trade during the proposed GTH session, and 
proposed Rule 5.1(d)(2) permits the Exchange to designate as 
eligible for trading during the proposed Curb session any option 
that the Exchange designates to trade during the proposed GTH 
session pursuant to proposed Rule 5.1(c)(2).
    \26\ See proposed Rule 5.1(c)(2). See also Amendment No. 1, 
supra note 10, at 18013-14.
    \27\ See proposed Rule 5.1(c)(2).
    \28\ See id.
---------------------------------------------------------------------------

    The Exchange would undertake a periodic review of the proposed 
eligibility criteria and, if necessary, remove equity options from the 
proposed GTH and Curb sessions that no longer meet the criteria.\29\ 
Specifically, the Exchange would engage in a semiannual review 
process--with two review cycles occurring as of January 1 and July 1 of 
each year--and utilize trading data from the previous six-month period 
to determine the equity option classes that meet the requirements of 
proposed Rule 5.1(c)(2).\30\ Eligible equity option classes designated 
by the Exchange would be permitted to commence trading during the 
proposed GTH and Curb sessions on the first trading day of February and 
August, respectively.\31\
---------------------------------------------------------------------------

    \29\ See proposed Rules 5.1(c)(2) and 5.1(d)(2). See also 
Amendment No. 1, supra note 10, at 18014. Proposed Rule 5.1(c)(2) 
sets forth the review process for the proposed GTH session, and 
pursuant to proposed Rule 5.1(d)(2), the same review process would 
apply for the proposed Curb session.
    \30\ See proposed Rules 5.1(c)(2)(A) and 5.1(d)(2). See also 
Amendment No. 1, supra note 10, at 18014. For the initial process to 
determine the equity options that meet the eligibility criteria, the 
Exchange would utilize data from the nearest six-month period ending 
either June 30 or December 31 prior to the launch of equity options 
trading in the proposed GTH and Curb sessions. See Amendment No. 1, 
supra note 10, at 18014.
    \31\ See Amendment No. 1, supra note 10, at 18014.
---------------------------------------------------------------------------

    If the Exchange determines that an equity option class trading 
during the proposed GTH and Curb sessions no longer meets the 
eligibility criteria, the Exchange would impose an up-to-18-month 
removal process.\32\ Specifically, under the proposal: (i) the equity 
option class may continue to trade in the proposed GTH and Curb 
sessions for up to 18 months from the date of such determination, and 
the Exchange would establish and provide reasonable advanced notice of 
the date on which the equity option class would be removed from trading 
in the proposed sessions (``removal date''), after which the equity 
option class may only trade in RTH; (ii) if, before the removal date, 
the Exchange determines that limited market activity in the equity 
option class during the proposed GTH session warrants an accelerated 
removal date, the Exchange may set a new, accelerated removal date and 
will provide at least seven days' advance notice of the new removal 
date; and (iii) notwithstanding the above, if, before the removal date, 
the Exchange determines pursuant to a semiannual review that the equity 
option class again meets the eligibility criteria, the removal date 
will no longer apply to the option class, and the option class may 
continue to trade in the proposed GTH and Curb sessions.\33\ The 
Exchange also reserves the discretion to remove an option class from 
the proposed GTH and Curb sessions for reasons other than those 
described above, and it proposes to provide at least 30 days' advance 
notice of such determination prior to the removal date.\34\ But if the 
Exchange determines that immediate removal is necessary in the interest 
of investor protection or the maintenance of fair and orderly markets, 
the Exchange may remove an equity options class from the proposed GTH 
and Curb sessions at any time and will provide notice of such 
determination as soon as practicable.\35\
---------------------------------------------------------------------------

    \32\ See proposed Rules 5.1(c)(2)(B)-(C) and 5.1(d)(2). See also 
Amendment No. 1, supra note 10, at 18014-15.
    \33\ See proposed Rules 5.1(c)(2)(B) and 5.1(d)(2).
    \34\ See proposed Rules 5.1(c)(2)(C) and 5.1(d)(2).
    \35\ See id.

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

[[Page 33007]]

    In addition to the proposed changes to Rules 5.1(c) and 5.1(d), the 
Exchange proposes rule amendments to support the proposed GTH and Curb 
trading for equity options. The Exchange proposes to amend Rule 5.1(e) 
to specify that, unlike GTH for index options, GTH for equity options 
will not occur on a holiday.\36\ Further, the Exchange proposes to 
amend the opening auction process in Rule 5.31 to incorporate GTH for 
equity options.\37\ Rule 5.31(b) currently provides that the queuing 
period for GTH for All Sessions Classes \38\ begins at 8:00 p.m., 15 
minutes prior to the commencement of GTH. The Exchange proposes to 
amend this rule to apply the existing queuing period beginning at 8:00 
p.m. to index options and establish a new queuing period for equity 
options in GTH that would commence at 7:15 a.m., which would be 15 
minutes prior to the commencement of the GTH session.\39\ The Exchange 
further proposes to amend Rule 5.31(d) to establish Opening Rotation 
Triggers processing for GTH equity options by duplicating the existing 
Opening Rotations Triggers processing for RTH equity options.\40\ 
Additionally, the Exchange proposes to amend Rule 5.31(c) to specify 
that existing rule text stating that opening auction updates may begin 
after 8:00 p.m. (previous day) for GTH trading is applicable for index 
options, and to establish 7:15 a.m. as the time after which opening 
auction updates may be disseminated for equity options during the 
proposed GTH session.\41\
---------------------------------------------------------------------------

    \36\ See Amendment No. 1, supra note 10, at 18016. Similarly, 
Rule 5.1(e) already states that there is no Curb Trading Hours on 
domestic and international holidays, and these provisions would also 
apply to equity options.
    \37\ See id. The Opening Auction Process is not applicable to 
the Curb session for equity options. See id.
    \38\ See Rule 1.1 (defining the term ``All Sessions Class'' as 
an options class that the Exchange lists for trading during all 
trading sessions).
    \39\ See Amendment No. 1, supra note 10, at 18016-17.
    \40\ See id.
    \41\ See id.
---------------------------------------------------------------------------

    The Exchange also proposes to amend its rules to address order 
routing away from the Exchange during the proposed GTH and Curb 
sessions.\42\ The Exchange states that its system is designed, at all 
times, to prevent trade-throughs and avoid displaying locked or crossed 
markets in accordance with the Linkage Plan.\43\ As proposed, Users' 
orders in equity options designated for trading during the proposed 
extended sessions would be eligible for routing just as they are during 
RTH.\44\ Specifically, the Exchange proposes to amend Rule 5.36(a) to 
change the time when the order routing process is first available from 
9:30 a.m. to ``market open.'' \45\ This proposed change is designed to 
enable Users to designate an order for routing (or not available for 
routing) during all trading sessions for equity options.\46\
---------------------------------------------------------------------------

    \42\ See proposed Rule 5.36. The Options Order Protection and 
Locked/Crossed Market Plan (``Linkage Plan'') requires U.S. options 
exchanges to establish a framework for providing order protection 
and addressing locked and crossed markets in eligible options 
classes. The Linkage Plan is a national market system plan approved 
by the Commission pursuant to Section 11A of the Act and Rule 608 
thereunder. See 15 U.S. C. 78k-1; 17 CFR 242.608. The full text of 
the Linkage Plan is available at <a href="https://www.theocc.com/getcontentasset/7fc629d9-4e54-4b99-9f11-c0e4db1a2266/dfc3d011-8f63-43f6-9ed8-4b444333a1d0/options_order_protection_plan.pdf">https://www.theocc.com/getcontentasset/7fc629d9-4e54-4b99-9f11-c0e4db1a2266/dfc3d011-8f63-43f6-9ed8-4b444333a1d0/options_order_protection_plan.pdf</a>.
    \43\ See Amendment No. 1, supra note 10, at 18016.
    \44\ See id. See also Rule 1.1 (stating that the term ``User'' 
means any Trading Permit Holders (``TPHs'') or Sponsored User who is 
authorized to obtain access to the System pursuant to Rule 5.5).
    \45\ See proposed Rule 5.36(a).
    \46\ See Amendment No. 1, supra note 10, at 18016.
---------------------------------------------------------------------------

    The Exchange also proposes to amend its rules regarding FLEX 
options.\47\ The Exchange proposes to amend Rule 5.71(b)(2) to specify 
that existing rule text stating that FLEX orders may be submitted after 
8:15 p.m. (previous day) is applicable to FLEX orders for an index 
option, and to establish that an order for an equity FLEX option that 
is designated to trade during the proposed GTH session may be submitted 
after 7:30 a.m.\48\ Similarly, the Exchange proposes to amend Rule 
5.71(b)(3) to specify that existing rule text stating that FLEX orders 
may be submitted after 4:15 p.m. is applicable to FLEX orders for an 
index option, and to establish that an order for a FLEX equity option 
that is designated to trade during the proposed Curb session may be 
submitted after 4:00 p.m.\49\
---------------------------------------------------------------------------

    \47\ See Rule 5.71 (Opening of FLEX Trading).
    \48\ See proposed Rule 5.71(b)(2). See also Amendment No. 1, 
supra note 10, at 18015-16.
    \49\ See proposed Rule 5.71(b)(3).
---------------------------------------------------------------------------

    Finally, Rule 9.20 provides required disclosures that a Trading 
Permit Holder must make to a customer prior to the customer trading 
during GTH and Curb. The Exchange proposes to update the rule to: (1) 
specify that existing references to the absence of an updated 
underlying index or portfolio value or intraday indicative value, and 
lack of regular trading in the securities underlying the index or 
portfolio apply to index options during GTH and Curb; and (2) add new 
references to the absence of an underlying price or lack of regular 
trading in the underlying equity for equity options trading in the 
proposed GTH and Curb sessions.\50\
---------------------------------------------------------------------------

    \50\ See Amendment No. 1, supra note 10, at 18017.
---------------------------------------------------------------------------

III. Discussion and Commission Findings

    After careful review, the Commission finds that the Exchange's 
proposed rule change, as modified by Amendment No. 1 (``Amended 
Proposal''), is consistent with the requirements of the Act and the 
rules and regulations thereunder applicable to a national securities 
exchange.\51\ In particular, the Commission finds that the Amended 
Proposal is consistent with Section 6(b)(1) of the Act,\52\ which 
requires, among other things, that the Exchange be so organized and 
have the capacity to be able to carry out the purposes of the Act and 
to comply, and to enforce compliance by its members and persons 
associated with its members, with the provisions of the Act, Commission 
rules and regulations thereunder, and its own rules; Section 6(b)(5) of 
the Act,\53\ which requires, among other things, that the rules of a 
national securities exchange be designed to promote just and equitable 
principles of trade, foster cooperation and coordination with persons 
engaged in regulating, clearing, settling, processing information with 
respect to and facilitating transactions in securities, 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; and Section 6(b)(8) of the Act,\54\ which requires 
that the rules of a national securities exchange not impose any burden 
on competition that is not necessary or appropriate in furtherance of 
the purposes of the Act.
---------------------------------------------------------------------------

    \51\ In approving this proposed rule change, the Commission has 
considered the proposed rule's impact on efficiency, competition, 
and capital formation. See 15 U.S.C. 78c(f).
    \52\ 15 U.S.C. 78f(b)(1).
    \53\ 15 U.S.C. 78f(b)(5).
    \54\ 15 U.S.C. 78f(b)(8).
---------------------------------------------------------------------------

    The Amended Proposal is novel in that no national securities 
exchange currently permits pre-RTH trading of multi-listed equity 
options or post-RTH trading of multi-listed equity options that are not 
ETP options. Even though equity securities are exchanged-traded outside 
of RTH,\55\ investors currently are unable to engage in exchange 
trading outside of RTH to utilize equity option trading strategies, 
including to hedge equity positions and mitigate downside risk in those 
positions.\56\ By extending the availability of equity options trading 
on the Exchange so that it begins at 7:30 a.m. and ends at 4:15 p.m., 
the Amended Proposal is reasonably designed to expand access to equity

[[Page 33008]]

options as a tool for risk mitigation and help investors protect 
existing equity positions against price movements.
---------------------------------------------------------------------------

    \55\ See Amendment No. 1, supra note 10, at 18012.
    \56\ See id.
---------------------------------------------------------------------------

    In addition, the Amended Proposal sets forth a measured approach 
for extending the Exchange trading sessions that are available for 
equity options, which is consistent with the Act.\57\ Currently, the 
earliest available extended trading sessions for equity securities on 
national securities exchanges commence at 4:00 a.m. and conclude at 
8:00 p.m.\58\ The Exchange has proposed significantly shorter 
timeframes for the proposed GTH and Curb sessions, which the Exchange 
states is appropriate because of the lack of industry experience with 
extended trading sessions for equity options.\59\ The Exchange states 
that limiting the proposed trading windows would allow for a paced 
introduction of these types of trading sessions for equity options.\60\ 
The Exchange also states that the limited timeframes will allow it to 
monitor and assess the development and functioning of the proposed GTH 
and Curb sessions for equity options.\61\
---------------------------------------------------------------------------

    \57\ See id.
    \58\ See id. at 18013.
    \59\ See id.
    \60\ See id.
    \61\ See id. The Exchange further states that it has discussed 
the proposal with numerous market participants, and, based on such 
discussions, it believes that market-makers, clearing firms, and 
other market participants can support the proposed trading 
timeframes from a personnel coverage perspective. See id.
---------------------------------------------------------------------------

    The Amended Proposal also is measured with respect to the equity 
option classes that would be available for trading during the 
Exchange's proposed extended trading sessions. Only highly liquid 
equity option classes that meet the eligibility criteria set forth in 
proposed Rules 5.1(c)(2) and (d)(2) would be available for trading 
during the proposed extended trading sessions. The Amended Proposal 
also caps the number of eligible equity option classes that would be 
available at 100, subject to another exchange offering extended trading 
of an equity option class that the Exchange has not offered, in which 
case the Exchange could add that class without it counting against the 
100 class cap.\62\ Moreover, the Amended Proposal sets forth a detailed 
review procedure to determine the equity option classes for inclusion 
in or removal from the proposed extended trading sessions. Further, the 
Amended Proposal modifies Exchange rules regarding series eligibility, 
the opening auction and opening of FLEX trading, order routing, and 
disclosure in a manner that is appropriately designed to facilitate the 
proposed extended trading of equity options.\63\
---------------------------------------------------------------------------

    \62\ See proposed Rules 5.1(c)(2) and 5.1(d)(2). Initially, the 
Exchange would offer a subset of qualifying symbols for extended 
session trading pursuant to this proposal. See <a href="https://www.cboe.com/notices/content/?id=59462">https://www.cboe.com/notices/content/?id=59462</a>.
    \63\ See proposed Rules 5.1, 5.20, 5.31, 5.36, 5.71, and 9.20.
---------------------------------------------------------------------------

    The Commission received comments on the proposal.\64\ The 
commenters expressed support for the proposal,\65\ and appreciation for 
its measured approach.\66\ A commenter discussed the classification of 
the proposed extended afternoon trading session,\67\ and the commenters 
discussed implementation matters relating to the collection and 
dissemination of consolidated market data and clearance and 
settlement.\68\ The Exchange responded in the Amended Proposal as well 
as a letter responding to the submitted comments.\69\

A. Extended Afternoon Session Classification

    One commenter requests clarification regarding how the Exchange 
would classify the proposed afternoon extended trading session of 4:00 
p.m.-4:15 p.m. and describes the potential implications for market 
participants of classifying this proposed session as GTH or RTH.\70\ 
The Amended Proposal designates the proposed extended afternoon session 
as a Curb trading session. The Curb designation aligns with existing 
Exchange terminology for the Curb trading session that already occurs 
after RTH on the Exchange for index options, and it would provide 
market participants with flexibility to specify the trading sessions 
outside of RTH during which their equity option orders may trade. In 
particular, the Curb designation would allow market participants to 
determine in which sessions their orders would trade outside of RTH, 
and for the exclusion of the proposed extended afternoon session if 
that is desired.\71\ In addition, the Curb designation provides clarity 
that market orders would not be permitted during the proposed extended 
afternoon session (and they also would not be permitted during the 
proposed extended morning session).\72\ Further, members with existing 
Exchange ports for RTH would not need new ports for the proposed 
extended trading sessions and would be able to utilize simple tags 
through their ports to indicate the trading session(s) in which an 
order may be executed.\73\ Accordingly, designating the proposed 
extended afternoon session as a Curb session is consistent with Section 
6(b)(5) of the Act.\74\
---------------------------------------------------------------------------

    \70\ See SIFMA First Letter, at 3-5. The Exchange previously 
considered classifying the proposed extended afternoon trading 
session as a new GTH session or, alternatively, as part of RTH. See 
Notice, supra note 3; see also SIFMA First Letter at 3. In light of 
that, this commenter sets forth pros and cons of each of those 
classifications. For example, the commenter states that designating 
the proposed extended afternoon session as GTH like the proposed 
extended morning session would force firms to create new FIX tags so 
that they could dictate whether their orders participate in either 
session. As a point of comparison, the commenter states that a firm 
currently may choose not to trade index options on the Exchange 
during the current Curb session for those options. The commenter 
also states that a GTH classification would ensure that firms' 
front-end platforms and trade systems follow important GTH protocols 
like preventing market orders, whereas market participants would 
seek clarity regarding whether market orders would be available 
under a RTH classification. See SIFMA First Letter at 3-4. As 
discussed, infra, the Exchange, in Amendment No. 1, designates the 
proposed extended afternoon session as a Curb session, which 
addresses this commenter's concerns.
    \71\ See Amendment No. 1, supra note 10, at 18012. Orders marked 
for ``All Sessions'' would automatically carry over and be 
actionable across all sessions, while those marked as RTH-Only would 
not be actionable during the proposed GTH or Curb sessions; orders 
marked as RTH and Curb would be actionable during the RTH and the 
Curb sessions. See id. n.19.
    \72\ See Amendment No. 1, supra note 10, at 18017 (stating that 
Users will not be able to submit market orders in equity options 
during the proposed GTH and Curb sessions, as is the case today 
during GTH and Curb for index options).
    \73\ See id. at 18012.
    \74\ See proposed Rule 5.1; Cboe Letter at 1.
---------------------------------------------------------------------------

B. Implementation Matters

    While broadly supporting the proposal, commenters state that, if it 
is approved, its implementation should be delayed in light of potential 
consolidated market data and clearance and settlement issues.\75\ The 
Commission's consideration of these matters, therefore, centers on 
consideration of an appropriate implementation period following this 
approval order. That is discussed in Section III.B.3 below, following 
discussion of the comments and Exchange responses regarding

[[Page 33009]]

consolidated market data and clearance and settlement, in Sections 
III.B.1 and III.B.2 below, respectively.
---------------------------------------------------------------------------

    \75\ See Nasdaq Letter; SIFMA First Letter; SIFMA Second Letter; 
SIFMA Third Letter.
---------------------------------------------------------------------------

1. Collection and Dissemination of Consolidated Market Data
    Commenters ask whether the Options Price Reporting Authority 
(``OPRA'') would have the ability and capacity to collect and 
disseminate equity option quotation and transaction information for all 
options exchanges during the extended trading sessions that the 
Exchange has proposed.\76\ OPRA has confirmed that its RTH platform 
would be able to support the proposed extended trading sessions for all 
exchanges, following a 30-day notice period to OPRA subscribers.\77\ 
Moreover, the Exchange states that OPRA RTH lines would be used for 
quote distribution and trade data for equity options trading during its 
proposed extended trading sessions.\78\
---------------------------------------------------------------------------

    \76\ See Nasdaq Letter at 1-2; SIFMA First Letter at 6.
    \77\ See Memorandum from the Division of Trading and Markets 
Regarding a March 4, 2026, Conference Call with Representatives of 
the Options Price Reporting Authority and the Securities Industry 
Automation Corporation, dated March 4, 2026.
    \78\ See Amendment No. 1, supra note 10, at 18018. The Exchange 
states that, although equity options activity would utilize OPRA RTH 
lines, GTH and Curb session trades would not be last trade eligible 
and would not count toward the daily high/low prices. See id. n. 56. 
The Exchange also states that Cboe proprietary index options will 
continue to be quoted and trade on the OPRA GTH system during GTH 
hours for index options. See id. n. 57.
---------------------------------------------------------------------------

2. Clearance and Settlement
    Commenters raise several considerations that relate to clearance 
and settlement of equity option transactions during the proposed 
extended sessions and the Options Clearing Corporation's (``OCC'') 
role,\79\ including: (i) timing and accuracy of start-of-day positions 
and Regulation SHO implications; \80\ (ii) potential impact on the 
clearing fund; (iii) potential additional capital requirements; (iv) 
potential margin impacts; (v) exercises and assignment notifications; 
(vi) settlement calculations; (vii) potential amendments to the 
Characteristics and Risks of Standardized Options, also known as the 
Options Disclosure Document (``ODD''); (viii) potential additional 
approvals for clearing members; and (ix) corporate actions and contract 
adjustments.\81\ One commenter characterizes handling of corporate 
actions as the biggest hurdle in a successful transition to extended 
trading sessions for equity options.\82\ This commenter states that the 
primary concerns in that regard revolve around corporate action events 
that significantly alter underlying positions and the timing of related 
announcements.\83\
---------------------------------------------------------------------------

    \79\ See SIFMA First Letter at 5-6; Nasdaq Letter at 2.
    \80\ See SIFMA First Letter at 5; SIFMA Second Letter at 2-3. 
With regard to Regulation SHO, this commenter states that start-of-
day positions must be accurate to correctly calculate and mark short 
and long positions; if clearing firm files, including contrary 
assignments, are delayed, start-of-day positions could be impacted, 
leading to potential mismarking or other issues. See SIFMA First 
Letter at 5.
    \81\ See SIFMA First Letter at 5-7; Nasdaq Letter at 2.
    \82\ See SIFMA First Letter at 7.
    \83\ Id.
---------------------------------------------------------------------------

    In the Amended Proposal and Cboe Letter, the Exchange states that 
the OCC has indicated it is operationally ready to support equity 
option trading during the proposed extended trading sessions and would 
utilize its existing processes and margin requirements.\84\ The 
Exchange states that, based on discussions with the OCC and certain 
clearing firms, the proposed extended trading sessions generally should 
not hinder existing processes, including with respect to start-of-day 
positions.\85\ The Exchange states that the OCC and clearing firms have 
indicated that their end-of-day processes are designed to complete on 
the same trading day, well before midnight.\86\ The Exchange states 
that, as such, it does not expect the proposed GTH session to have any 
impact on daily processing when processing occurs in the normal course, 
and the proposed GTH session is not a concern from the Regulation SHO 
perspective.\87\
---------------------------------------------------------------------------

    \84\ See Amendment No. 1, supra note 10, at 18019; Cboe Letter 
at 2-3. The Exchange states that OCC already clears during extended 
trading sessions for certain Cboe index options as well as certain 
ETF options and other products that are eligible pursuant to 
Exchange rules to trade until 4:15p.m. as part of RTH and, 
therefore, has the functionality to support the proposed GTH and 
Curb trading sessions for equity options. See Amendment No. 1, supra 
note 10, at 18019; Cboe Letter at 2-3.
    \85\ See Amendment No. 1, supra note 10, at 18013. See also Cboe 
Letter at 2. The Exchange states that clearing firms have indicated 
that the proposed extended trading session times generally should 
not hinder processing because such processing is typically completed 
on the trading day. See Amendment No. 1, supra note 10, at 18013.
    \86\ See Amendment No. 1, supra note 10, at 18013, 18019.
    \87\ See id. See also Cboe Letter at 2. The Exchange also states 
that it and the OCC intend to apply to the proposed extended equity 
option trading sessions the existing authorization procedures that 
apply to GTH trading of index options on the Exchange. See Amendment 
No. 1, supra note 10, at 18019. An Exchange member that is already 
authorized for GTH trading of index options would not require any 
further Exchange or OCC authorizations to trade equity options 
during the proposed GTH session. Exchange members that are not 
currently authorized for GTH trading of index options but wish to 
trade equity options during the proposed GTH session would be 
required to receive authorization from both the OCC and the Exchange 
before doing so. No special authorization is required for 
participation in the proposed Curb session. See Amendment No. 1, 
supra note 10, at 18019.
---------------------------------------------------------------------------

    The Exchange acknowledges that a corporate action that 
significantly impacts the value of a security may be announced while 
the equity option overlying the security is trading during the proposed 
Curb session.\88\ The Exchange states that if such an announcement 
results in a halt of the underlying security, trading in the equity 
option should also halt.\89\ The Exchange also states that 
announcements of the effectiveness of a corporate action made after 
4:00 p.m. are similar to the announcement of a corporate action that is 
made prior to 4:00 p.m.\90\ The Exchange states that, as such, 
corporate action announcements made during the proposed extended 
afternoon session would generally have the same impact as corporate 
actions that are announced as effective during the RTH session.\91\
---------------------------------------------------------------------------

    \88\ See Amendment No. 1, supra note 10, at 18014.
    \89\ See id.
    \90\ See id.
    \91\ See id. The Exchange also states that it continues to 
participate in industry discussions to address concerns about late 
corporate action notifications and the impacts they can have on 
option contract adjustments and option positions during all trading 
sessions (not just extended trading hours). See Cboe Letter at 2. 
Further, the Exchange states that it is preparing a separate rule 
filing that would provide the Exchange with authority to address 
certain scenarios as part of obvious error rules. See id.
---------------------------------------------------------------------------

3. Implementation Timing
    As noted above, the Commission's consideration of the consolidated 
market data and clearance and settlement matters raised by commenters 
centers on consideration of an appropriate implementation period 
following this approval order. One commenter requests that any 
Commission approval of the proposed rule change be contingent upon 
OPRA's readiness to permit all OPRA participant exchanges to trade 
during the proposed extended sessions and OCC's readiness to clear 
equity options during the proposed extended sessions.\92\ The other 
commenter requests that the proposed rule change have an effective date 
no less than 120 days from the date it is approved, which the commenter 
states would be a reasonable time period for market participants to 
address outstanding issues.\93\
---------------------------------------------------------------------------

    \92\ See Nasdaq Letter at 1-2.
    \93\ See SIFMA First Letter at 7; SIFMA Second Letter at 3. See 
also SIFMA Third Letter (clarifying that its request for a 120-day 
implementation delay applies to the Exchange's proposal but not 
other options exchange proposals to extend trading hours, and urging 
harmonization across options exchange proposals for extended 
trading). SIFMA's First Letter requests an effective date of no less 
than 120 business days (emphasis added), and SIFMA's Second Letter 
requests an effective date of no less than 120 days (without 
specifying ``business'' days), in either case to run from the date 
of approval of the Amended Proposal. See SIFMA First Letter at 7; 
SIFMA Second Letter at 3. SIFMA's Third Letter characterizes its 
prior two letters as having requested a 120-day implementation delay 
(without specifying ``business'' days). See SIFMA Third Letter at 2.

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

[[Page 33010]]

    The Exchange states that some firms are ready to trade equity 
options in the proposed extended trading sessions, but it also 
acknowledges that some firms may require additional time to make 
necessary system modifications.\94\ The Exchange states that it would 
not launch the proposed equity option extended trading sessions until 
at least 30 days following any Commission approval of this proposed 
rule change, and approximately three months after the Exchange's 
publication of technical specifications related to the proposed 
extended trading sessions.\95\ The Exchange also states that the OCC 
must file a proposed rule change to support the proposed extension of 
trading hours for equity options, and that the Exchange would not 
launch its proposed extended trading sessions for equity options until 
after any Commission approval of the OCC's rule filing.\96\
---------------------------------------------------------------------------

    \94\ See Cboe Letter at 2. The Exchange states that certain 
firms have requested that the Exchange launch trading in the 
proposed GTH and Curb sessions as soon as possible. See id.
    \95\ See id. See also Amendment No. 1, supra note 10, at 18019. 
The Exchange published these technical specifications on April 15, 
2026; they are available at: <a href="https://www.cboe.com/notices/content/?id=59462">https://www.cboe.com/notices/content/?id=59462</a>.
    \96\ See Amendment No. 1, supra note 10, at 18017, n. 52.
---------------------------------------------------------------------------

    The Exchange's timing for the commencement of the proposed extended 
trading sessions must be consistent with Section 6(b)(1) of the 
Act,\97\ which requires, among other things, that the Exchange is so 
organized and has the capacity to comply with the provisions of the 
Act, Commission rules and regulations thereunder, and its own rules; 
Section 6(b)(5) of the Act, which requires, among other things, that 
the Exchange's rules be designed to foster cooperation with persons 
engaged in regulating, clearing, settling, processing information with 
respect to and facilitating transactions in securities, and 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; and Section 6(b)(8) of the Act, which requires that 
the rules of a national securities exchange not impose any burden on 
competition that is not necessary or appropriate in furtherance of the 
purposes of the Act. These requirements have been met here because the 
Exchange's proposed extended trading sessions would not commence until 
at a minimum: (i) OPRA is prepared to collect and disseminate quote and 
trade information for any exchange that adopts the same proposed 
extended trading sessions, (ii) the OCC is prepared to clear and settle 
trades for any such exchange, and (iii) exchange members are afforded a 
reasonable amount of time to prepare for extended equity option 
trading.
---------------------------------------------------------------------------

    \97\ 15 U.S.C. 78f(b)(1).
---------------------------------------------------------------------------

    As discussed above, OPRA has confirmed its readiness to collect and 
disseminate quote and trade information for any exchange, and the 
Exchange would utilize an OPRA platform that would be available to any 
exchange seeking to offer the same extended trading sessions as the 
Exchange. Since OPRA would provide a 30-day notice period to its 
subscribers, the Commission understands that the Exchange would not 
commence the proposed extended session trading until after that 30-day 
notice period has concluded.
    With respect to OCC readiness and exchange member readiness, the 
Exchange effectively has committed not to implement the proposed 
extended session trading until the later of: (i) 30 days following the 
date of this approval order,\98\ (ii) approximately three months after 
the Exchange's publication of technical specifications,\99\ and (iii) 
any Commission approval of the proposed rule change that the OCC must 
file with the Commission pursuant to Section 19(b) of the Act.\100\ 
Multi-listed equity options are standardized options and, as such, 
transactions in them that occur during the proposed extended trading 
session must be cleared and settled by the OCC.\101\ Because the 
Exchange would not implement the proposed extended trading sessions 
until after effectiveness of the OCC's proposed rule change, the 
Exchange has acknowledged that it would not implement the proposed 
extended sessions until the OCC is prepared to clear and settle equity 
option trades that occur during those sessions.
---------------------------------------------------------------------------

    \98\ See supra note 95 and accompanying text.
    \99\ See id.
    \100\ 15 U.S.C. 78s(b). In light of the date of this approval 
order, the time period countenanced by (i) is moot because the time 
periods countenanced by (ii) and (iii) will run past the date that 
is 30 days following the date of this approval order. See supra note 
95 and accompanying text. In addition, as noted above, the 
Exchange's implementation of the Amended Proposal also is contingent 
on the conclusion of OPRA's 30-day notice period to its subscribers.
    \101\ See 17 CFR 240.9b-1.
---------------------------------------------------------------------------

    Taken together, the Exchange's proposed implementation timing is 
designed to provide Exchange members with reasonable time and 
opportunity to prepare for the proposed extended trading sessions, and 
therefore consistent with the Act.\102\ The Exchange's publication of 
technical specifications in mid-April enabled Exchange members to begin 
technical preparations for the proposed extended sessions prior to this 
approval order. The approximately three-month implementation period 
following such publication would conclude before the 120-day post-
approval implementation period requested by one commenter. But to the 
extent Exchange members already have begun preparations, they may 
require less time to become fully prepared than 120 days following this 
approval order. In addition, the proposed rule change that the OCC must 
file with the Commission is subject to a statutory timeframe during 
which Exchange members can continue their preparations, including 
obtaining any necessary trading authorizations from the Exchange or the 
OCC.\103\
---------------------------------------------------------------------------

    \102\ The Exchange has provided FAQs on its website to assist 
market participants with their preparations for the proposed 
extended trading sessions for multi-listed equity options. See 
<a href="https://www.cboe.com/document/tech-spec/content/technical-specifications/equity-options-extended-trading-hours-faq/overview">https://www.cboe.com/document/tech-spec/content/technical-specifications/equity-options-extended-trading-hours-faq/overview</a>.
    \103\ See supra note 87. See also Section 19(b) of the Act; 15 
U.S.C. 78s(b).
---------------------------------------------------------------------------

    For the foregoing reasons, the Commission finds that the Amended 
Proposal is consistent with the Act and the rules and regulations 
thereunder applicable to a national securities exchange.

IV. Conclusion

    It is Therefore Ordered, pursuant to Section 19(b)(2) of the Act, 
that the proposed rule change, as modified by Amendment No. 1, (SR-
CBOE-2025-079) be, and it hereby is, approved.

    For the Commission, by the Division of Trading and Markets, 
pursuant to delegated authority.\104\
