Self-Regulatory Organizations; Cboe EDGX Exchange, Inc.; Notice 
of Filing and Immediate Effectiveness of a Proposed Rule Change To 
Amend Its Fee Schedule To Implement an Exchange Order Entry Protocol 
Migration Program

August 28, 2026.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on August 20, 2026, Cboe EDGX Exchange, Inc. (the ``Exchange'' or 
``EDGX'') filed with the Securities and Exchange Commission (the 
``Commission'') the proposed rule change as described in Items I, II, 
and III below, which Items have been prepared by the Exchange. The 
Commission is publishing this notice to solicit comments on the 
proposed rule change from interested persons.

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

    The Exchange proposes to amend its fee schedule to implement an 
Exchange Order Entry Protocol Migration Program. 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/equities/regulation/rule_filings/edgx/">https://www.cboe.com/us/equities/regulation/rule_filings/edgx/</a>), and at the 
principal office of the Exchange.

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

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

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

1. Purpose
    The purpose of the proposed rule change is to introduce the 
Exchange's Order Entry Protocol Migration Program (the, ``Program''). 
As described in further detail below, the Program is intended to 
provide Members,\3\ subject to certain conditions, fee credits for 
logical ports that Members establish solely for use as a back-up 
connection during an Exchange initiated order entry protocol migration; 
e.g., migrating from BOEv2 \4\ logical ports to BOEv3 logical ports.
---------------------------------------------------------------------------

    \3\ The term ``Member'' shall mean any registered broker or 
dealer that has been admitted to membership in the Exchange. A 
Member will have the status of a ``member'' of the Exchange as that 
term is defined in Section 3(a)(3) of the Act. Membership may be 
granted to a sole proprietor, partnership, corporation, limited 
liability company or other organization which is a registered broker 
or dealer pursuant to Section 15 of the Act, and which has been 
approved by the Exchange. See Rule 1.5(n).
    \4\ The term BOE refers to Cboe Binary Order Entry (``BOE''), 
which is a proprietary order entry protocol. See ``Cboe Titanium 
U.S. Equities BOE Specification,'' available at: <a href="https://www.cboe.com/document/tech-spec/content/technical-specifications/cboe-titanium-u.s.-equities-boe-specification">https://www.cboe.com/document/tech-spec/content/technical-specifications/cboe-titanium-u.s.-equities-boe-specification</a>.
---------------------------------------------------------------------------

    Specifically, the proposed Program would provide that during an 
Exchange initiated order entry protocol migration (``Migration'') a 
Member may establish a logical port to serve solely as a backup 
connection (``Redundant Logical Port'') during the Member's migration 
from a prior logical port protocol to the current logical port protocol 
(``New Logical Port''). The Redundant Logical Port may only be used for 
Exchange issues directly related to the Migration that prevent the 
Member from using their New Logical Port, thereby requiring the Member 
to instead use their Redundant Logical Port to enter orders and/or 
quotes into the System.\5\ A Member shall be eligible for a credit of 
the monthly logical port fee(s) that would otherwise be assessed for 
such Redundant Logical Port, provided that: (i) the Member notifies the 
Exchange's Trade Desk, in a manner specified by the Exchange, that the 
Redundant Logical Port being established is intended to serve only as a 
backup connection during a Migration; (ii) the Redundant Logical Port 
is canceled by the Member within 30 calendar days of the Member 
designating such logical port as a Redundant Logical Port; (iii) any 
orders and/or quotes entered by the Member into the Redundant Logical 
Port must be due to an Exchange issue directly related to the 
Migration; and (iv) within 30 days following such cancelation, the 
Member submits to the Exchange's Trade Desk a request for a credit of 
the fees assessed by the Exchange for the Redundant Logical Port.
---------------------------------------------------------------------------

    \5\ The term ``System'' shall mean the electronic communications 
and trading facility designated by the Board through which 
securities orders of Users are consolidated for ranking, execution 
and, when applicable, routing away. See Rule 1.5(cc).
---------------------------------------------------------------------------

    Following receipt of the credit request, the Exchange will review 
the Redundant Logical Port's order and quote usage for the period 
during which the Redundant Logical Port was designated as such and 
confirm the Member's compliance with (i)-(iv), above. If the Member 
satisfies these requirements the Exchange will apply a credit for the 
fees assessed for the Redundant Logical Port to the Member's invoice 
for the billing cycle following the Exchange's confirmation.
    The Exchange is implementing the Program to credit logical port 
fees back to Members where their establishment of a Redundant Logical 
Port was solely for the purpose of creating backup logical ports to be 
used in the event a Member's New Logical Port, through no fault of 
their own, is not available for use, thereby preventing their access to 
the Exchange. In this regard, by creating Redundant Logical Ports, 
Members can responsibly ensure that they will maintain access to the 
Exchange even in the event where their New Logical Ports, which were 
created only because of an Exchange initiated order entry protocol 
migration, are not available for use because of an Exchange issue 
(e.g., through clerical or ministerial error, a Member's New Logical 
Port was not created by the Exchange). In such a scenario, the Exchange 
does not believe it appropriate to assess Members logical port fees for 
Redundant Logical Port fees that are, absent an Exchange issue, not 
being utilized and instead are being

[[Page 56490]]

created by Members to responsibly ensure they always maintain access to 
the Exchange.
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.\6\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \7\ 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) \8\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.

promote just and equitable principles of trade, to foster cooperation

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

    The Exchange believes it is reasonable to provide a credit of the 
applicable monthly logical port fees only where a Member establishes a 
Redundant Logical Port in connection with Migration. In this 
circumstance, the Member is adopting a New Logical Port not as a matter 
of its own business discretion, but solely because the Exchange has 
elected to migrate to an updated order entry protocol. The Redundant 
Logical Port that a Member maintains during such a transition is 
therefore directly attributable to an Exchange driven change and exists 
solely to preserve the Member's continued access to the Exchange in the 
event the Member's New Logical Port, through no fault of the Member, 
does not function as intended due to an Exchange Migration issue. By 
contrast, the Exchange does not believe it would be reasonable or 
appropriate to extend the credit to a logical port that a Member 
establishes in connection with a Member initiated change, because in 
that case the additional connection reflects the Member's own 
operational preferences and business decisions (e.g., migrating from 
FIX ports to BOE ports) rather than a transition necessitated by the 
Exchange. Limiting the credit to a Migration thus appropriately ties 
the fee credit to the specific circumstance the Program is designed to 
address, namely, the operational burden placed on Members as a direct 
result of the Exchange's decision to migrate to a new order entry 
protocol.
    The Exchange further believes that the 30-calendar day period 
during which a Member may maintain a Redundant Logical Port and remain 
eligible for the credit is reasonable. A migration to a new order entry 
protocol presents operational risk for Members, and the 30-calendar day 
overlap period affords Members an adequate opportunity to establish, 
test, and gain confidence in the operation of their New Logical Port 
before decommissioning the logical port that supported the prior 
protocol. Permitting this limited period of overlap reduces the risk 
that a Member will prematurely cancel a functioning connection and 
thereby jeopardize its access to the Exchange during a critical 
transition. At the same time, the Exchange believes 30-calendar days is 
an appropriately tailored period that is long enough to allow Members 
to develop confidence in the New Logical Port, while ensuring that the 
credit remains tied to the migration and is not used to subsidize a 
Member's maintenance of duplicative connectivity on an indefinite 
basis. The Exchange also believes that measuring this period in 
calendar days, rather than business days, promotes clarity and ease of 
administration for both Members and the Exchange as it removes the need 
to have to account for holidays and weekends.
    The Exchange also believes the proposed Program is reasonable 
because it is designed to alleviate the migration related costs that 
Members would otherwise incur solely as a result of an Exchange 
initiated order entry protocol migration and to promote Member 
confidence throughout the Migration process. Absent the Program, a 
Member that responsibly establishes a Redundant Logical Port to 
preserve its access to the Exchange during a Migration would be 
assessed the full monthly logical port fee for a connection that, 
absent an Exchange Migration related issue, it would not otherwise use. 
By crediting such fees, the Program removes a financial disincentive to 
maintaining a backup connection and encourages Members to take 
reasonable measures to ensure continuity of access during the 
transition. The Exchange believes that relieving Members of these 
costs, which arise only because of an Exchange initiated change, 
supports a more orderly Migration process, reduces operational risk to 
Members and the market, and thereby removes impediments to and perfects 
the mechanism of a free and open market and a national market system, 
consistent with Section 6(b)(5) of the Act.
    The Exchange also believes the proposed rule change is consistent 
with Section 6(b)(4) of the Act,\12\ which requires that Exchange rules 
provide for the equitable allocation of reasonable dues, fees, and 
other charges among its Members and other persons using its facilities. 
The Exchange believes the proposed Program provides for an equitable 
allocation of reasonable fees because the credit is available to all 
Members on the same terms and is governed by the same objective 
conditions set forth in (i) through (iv) above. Any Member that 
establishes a Redundant Logical Port during an Exchange Migration, and 
that satisfies those conditions, is eligible for the same credit of the 
monthly logical port fees that would otherwise be assessed for such 
Redundant Logical Port. The Exchange believes it is equitable to 
allocate the cost of a Redundant Logical Port from Members in this 
limited circumstance because the underlying connection is established 
only in response to an Exchange initiated

[[Page 56491]]

change and, absent an Exchange Migration related issue, is not used by 
the Member to enter orders and quotes into the System.
---------------------------------------------------------------------------

    \12\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

    For substantially the same reasons, the Exchange believes the 
proposed Program is equitable and not unfairly discriminatory in 
accordance with Section 6(b)(5) of the Act. The Program applies 
uniformly to all similarly situated Members, as any Member that 
establishes a Redundant Logical Port in connection with an Exchange 
Migration and satisfies conditions (i) through (iv) is eligible for the 
credit on the same basis, regardless of the type or size of the Member. 
The credit is not available on a discretionary or selective basis; 
rather, it is applied according to the objective, transparent criteria 
set forth in the proposed rule text, following the Exchange's review of 
the Redundant Logical Port's order and quote usage and confirmation of 
the Member's compliance with those criteria. Because the availability 
of the credit turns solely on the objective circumstances of an 
Exchange Migration and the Member's compliance with uniform conditions, 
the Exchange believes the proposed Program does not permit unfair 
discrimination between customers, issuers, brokers, or dealers.

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 proposed rule change 
does not impose any burden on intramarket competition as the Redundant 
Logical Port credit is available to all Members and Trading Permit 
Holders (``TPHs'') \13\ on each of the EDGX's affiliated exchanges--BYX 
Exchange, Incorporated, EDGA Exchange, Inc., BZX Exchange, Inc., Cboe 
Exchange, Inc., and C2 Exchange, Inc. (together with EDGX, the 
``Affiliated Exchanges''). Additionally, as noted above, the Redundant 
Logical Port fee credit is uniformly to all Members and TPHs, across 
each of the Affiliated Exchanges, on the same terms and under the same 
objective conditions set forth in (i) through (iv) above. The Program 
applies uniformly to all similarly situated Members and TPHs, 
regardless of the type or size of the Member or TPH, and is not 
available on a discretionary or selective basis.
---------------------------------------------------------------------------

    \13\ The terms ``Trading Permit Holder'' and ``TPH'' have the 
meaning set forth in the Bylaws.'' See Cboe Exchange, Inc., Rule 1.1 
Definitions; see also Bylaws of the Cboe Exchange, Inc., Section 1.1 
Definitions, ``The term ``Trading Permit Holder'' means any 
individual, corporation, partnership, limited liability company or 
other entity authorized by the Rules that holds a Trading Permit. If 
a Trading Permit Holder is an individual, the Trading Permit Holder 
may also be referred to as an ``individual Trading Permit Holder.'' 
If a Trading Permit Holder is not an individual, the Trading Permit 
Holder may also be referred to as a ``TPH organization.'' A Trading 
Permit Holder is a ``member'' solely for purposes of the Act; 
however, one's status as a Trading Permit Holder does not confer on 
that Person any ownership interest in the Exchange; see also Rule 
1.1 of the C2 Exchange, Inc, ``The terms ``Trading Permit Holder'' 
or ``TPH'' mean an Exchange-recognized holder of a Trading Permit. A 
Trading Permit Holder is deemed a ``member'' under the Exchange 
Act.''
---------------------------------------------------------------------------

    Although the Program relates to logical ports established in 
connection with an Exchange initiated order entry protocol migration, 
it does not favor any particular type of market participant because any 
Member that establishes a Redundant Logical Port during an Exchange 
initiated migration and satisfies conditions (i) through (iv) is 
eligible for the same credit. Accordingly, the Exchange believes the 
proposed Program is equitable and not unfairly discriminatory.
    Furthermore, the proposed rule change does not impose any burden on 
intermarket competition. The Program is limited to fees and credits for 
Redundant Logical Ports that Members establish solely because of an 
Exchange initiated order entry protocol migration, and it does not 
disadvantage other exchanges. To the extent the Program makes EDGX more 
attractive or favorable by reducing migration-related costs and 
supporting continuity of Member access to the Exchange, it will help to 
foster competition among exchanges.

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

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

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

    The foregoing rule change has become effective pursuant to Section 
19(b)(3)(A) of the Act \14\ and paragraph (f) of Rule 19b-4 \15\ 
thereunder. At any time within 60 days of the filing of the proposed 
rule change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission will institute proceedings to 
determine whether the proposed rule change should be approved or 
disapproved.
