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

    Cboe Exchange, Inc. (the ``Exchange'' or ``Cboe Options'') proposes 
to amend fees related to the Cboe Legacy Silexx platform versions. The 
text of the proposed rule change is provided in Exhibit 5.
    The text of the proposed rule change is also available on the 
Exchange's website (<a href="http://www.cboe.com/AboutCBOE/CBOELegalRegulatoryHome.aspx">http://www.cboe.com/AboutCBOE/CBOELegalRegulatoryHome.aspx</a>), at the Exchange's Office of the 
Secretary, and at the Commission's Public Reference Room.

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

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

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

1. Purpose
    The Exchange proposes to amend fees related to the Cboe Legacy 
Silexx platform versions (collectively, the ``Legacy Platforms'' as 
further described herein) and to extend the time of a fee waiver 
currently offered for Cboe Silexx, effective May 1, 2025.\3\ By way of 
background, the Exchange offers several versions of its Silexx 
platform. Originally, the Exchange offered the following versions of 
the Silexx platform: Basic, Pro, Pro Plus Risk and Buy-Side Manager 
(``Legacy Platforms''). The Legacy Platforms are designed so that a 
User may enter orders into the platform to send to the executing 
broker, including TPHs, of its choice with connectivity to the 
platform. The executing broker can then send orders to Cboe Options (if 
the broker-dealer is a Trading Permit Holder (``TPH'')) or other U.S. 
exchanges (and trading centers) in accordance with the User's 
instructions. Users cannot directly route orders through any of the 
Legacy Platforms to an exchange or trading center nor is the platform 
integrated into or directly connected to Cboe Option's System. In 2019, 
the Exchange made available a new version of the Silexx

[[Page 22432]]

platform, Silexx FLEX, which supports the trading of FLEX Options and 
allows authorized Users with direct access to the Exchange to establish 
connectivity and submit orders directly to the Exchange.\4\ In 2020, 
the Exchange made an additional version of the Silexx platform 
available, Cboe Silexx, which supports the trading of non-FLEX Options 
and allows authorized Users with direct access to the Exchange to 
establish connectivity and submit orders directly to the Exchange.\5\ 
Cboe Silexx is essentially the same platform as Silexx FLEX, with the 
same applicable functionality, except that it additionally supports 
non-FLEX trading. As noted in previous filings, the Exchange is in the 
process of transitioning the Legacy Platforms to the current version of 
Cboe Silexx and Silexx FLEX.\6\ As the Exchange is actively 
transitioning away from the Legacy Platforms, and in the meantime is 
expending time and resources to maintain both platforms, the Exchange 
previously proposed to increase the fees for the Legacy Platforms.\7\ 
For this same reason, the Exchange now proposes to increase the API fee 
for the Legacy Platforms from a $200/month/login ID fee to $2,000/
month/login ID for logins 1-5 and a fee of $0/month/login ID for logins 
6-10 for a firm and shall be capped at 10 login IDs.
---------------------------------------------------------------------------

    \3\ The Exchange initially submitted the proposed rule change on 
May 1, 2025 (SR-CBOE-2025-032). On May 12, 2025, the Exchange 
withdrew that filing and submitted this filing.
    \4\ See Securities Exchange Act Release No. 87028 (September 19, 
2019) 84 FR 50529 (September 25, 2019) (SR-CBOE-2019-061). Only 
Users authorized for direct access and who are approved to trade 
FLEX Options may trade FLEX Options via Cboe Silexx. Only authorized 
Users and associated persons of Users may establish connectivity to 
and directly access the Exchange, pursuant to Rule 5.5 and the 
Exchange's technical specifications.
    \5\ See Securities Exchange Act Release No. 88741 (April 24, 
2020) 85 FR 24045 (April 30, 2020) (SR-CBOE-2020-040). Only 
authorized Users and associated persons of Users may establish 
connectivity to and directly access the Exchange, pursuant to Rule 
5.5 and the Exchange's technical specifications.
    \6\ See Securities Exchange Release No. 98722 (October 11, 2023) 
88 FR 71619 (October 17, 2023) (SR-CBOE-2023-060). Only authorized 
Users and associated persons of Users will continue to be able to 
establish connectivity to and directly access the Exchange, pursuant 
to Rule 5.5 and the Exchange's technical specifications. 
Unauthorized Users will not be able to connect directly to the 
Exchange. The new Cboe Silexx platform will function in the same 
manner as the Legacy Platforms versions currently available to 
Users: it will be completely voluntary; orders entered through the 
platform will receive no preferential treatment as compared to 
orders electronically sent to Cboe Options in any other manner; 
orders entered through the platform will be subject to current 
trading rules in the same manner as all other orders sent to the 
Exchange, which is the same as orders that are sent through the 
Exchange's System today; the Exchange's System will not distinguish 
between orders sent from Silexx and orders sent in any other manner; 
and Silexx will provide technical support, maintenance and user 
training for the new platform version upon the same terms and 
conditions for all Users. The Exchange plans to decommission the 
Legacy Platforms at a future to-be-determined date, at which time 
the Legacy Platforms will be unavailable to users.
    \7\ See Securities Exchange Release No. 102185 (January 14, 
2025) 90 FR 7200 (January 21, 2025) (SR-CBOE-2025-001); Securities 
Exchange Release No. 102398 (February 11, 2025) 90 FR 9781 (February 
18, 2025) (SR-CBOE-2025-005); and Securities Exchange Release No. 
102724 (March 13, 2025) 90 FR 14288 (March 31, 2025) (SR-CBOE-2025-
016).
---------------------------------------------------------------------------

    The Exchange previously introduced a fee waiver of two months to 
allow users of Cboe Silexx to transition to the new version of the 
platform without incurring duplicative Login ID and Market Data Feed 
fees for access to both the old and new versions of Cboe Silexx during 
this transitional period.\8\ The Exchange further noted that it 
believed not assessing duplicative fees for Users transitioning to Cboe 
Silexx would serve as an incentive to market participants to start 
using the Cboe Silexx platform, while also providing time and 
flexibility for such Users to become familiar with and fully acclimated 
to the new platform.\9\ For this same reason, the Exchange now proposes 
to extend the existing fee waiver for Cboe Silexx Login ID fees that 
are incurred during the migration from a period of two months to three 
months, which does not need to be consecutive.
---------------------------------------------------------------------------

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.\10\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \11\ 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) \12\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers. Additionally, the Exchange also believes the 
proposed rule change is consistent with Section 6(b)(4) of the Act, 
which requires that Exchange rules provide for the equitable allocation 
of reasonable dues, fees, and other charges among its TPHs and other 
persons using its facilities.

    \11\ 15 U.S.C. 78f(b)(5).
    \12\ Id.
---------------------------------------------------------------------------

    In particular, the Exchange also believes the proposed fee increase 
for the API for the Legacy Platforms is reasonable, equitable, and not 
unfairly discriminatory because the fee will apply to all users of the 
Legacy Platforms who utilize the API. Additionally, the Exchange 
believes the proposed fee is reasonable as it accounts for 
administrative costs that Cboe Silexx is incurring, but not charging 
users, to maintain support for Legacy Platforms while Cboe Silexx 
transitions away from the Legacy Platforms. As noted earlier, the 
Exchange is in the process of transitioning the Legacy Platforms to the 
current version of Cboe Silexx and Silexx FLEX. The Exchange believes 
that increasing the API fee for the Legacy Platforms also serves as an 
incentive to market participants to transition to the current version 
of Cboe Silexx from the Legacy Platforms.\13\ Further, the Exchange 
notes that the proposed, new fee structure for the API for the Legacy 
Platforms maxes out at a monthly fee of $10,000. While the Exchange 
would like to incentivize market participants to transition to the 
current version of Cboe Silexx, it does not want the increase in the 
API fee to be overly prohibitive for firms that may have a larger 
number of users that they are working to transition. The Exchange also 
believes that capping the number of API Login IDs a firm may utilize 
will further incentivize market participants to transition to the 
current version of Cboe Silexx. The Exchange reiterates that the 
Silexx, including the Legacy Platforms and Cboe Silexx, is entirely 
optional for participants and such connectivity is not required to 
access the Exchange. Of further note, the API feature is an additional 
optional feature on top of the optional connectivity the Exchange 
offers to connect. For the above reasons, the Exchange believes that 
proposed fee increase is reasonable,

[[Page 22433]]

equitable, and not unfairly discriminatory.
---------------------------------------------------------------------------

    \13\ The Exchange has previously introduced incentives to assist 
in the migration from the Legacy Platforms to the current version of 
Cboe Silexx and Silexx Flex by introducing a Data Management fee for 
users of Legacy Platforms and waiving duplicative Login ID and 
Market Data Feed fees for Cboe Silexx during a user's transition 
period. See Securities Exchange Release No. 99111 (December 7, 2023) 
88 FR 86411 (December 13, 2023) (SR-CBOE-2023-064) and Securities 
Exchange Release No. 98722 (October 11, 2023) 88 FR 71619 (October 
17, 2023) (SR-CBOE-2023-060).
---------------------------------------------------------------------------

    Next, the Exchange believes that increasing the time permitted for 
waivers is also reasonable, equitable and not unfairly discriminatory 
because the waiver applies to users who are already subject to a 
monthly Login ID fee (albeit for the Legacy Platform), as well as 
Market Data Feed fees (for those receiving it on the Legacy Platform). 
Additionally, the fee waiver period will be limited to the timeframe 
during which such Users have access to the old and new version of Cboe 
Silexx and would otherwise result in duplicative fees. The Exchange 
further believes a fee waiver of three months is an appropriate and 
reasonable amount of time for Users to become familiar with and fully 
acclimated to the new platform and therefore able to terminate their 
connection to the Legacy Platforms. The Exchange notes that a timeline 
of three months is more fitting now, as many of the users who are some 
of the final users to transition from the Legacy Platforms may have 
more nuanced issues to address while they are migrating to Cboe Silexx.
    Finally, the Exchange notes that use of the platform is 
discretionary and not compulsory, as users can choose to route orders, 
including to Cboe Options, without the use of the platform. Indeed, the 
Legacy Platforms are not an exclusive means of trading, and if market 
participants believe that other products, vendors, front-end builds, 
etc. available in the marketplace are more beneficial or cost effective 
than the Legacy Platforms (or the current version of Cboe Silexx and 
Silexx FLEX), they may simply use those products instead, including for 
routing orders to the Exchange (indirectly or directly if they are 
authorized Users). The Exchange makes the platform available as a 
convenience to market participants, who will continue to have the 
option to use any order entry and management system available in the 
marketplace to send orders to the Exchange and other exchanges; the 
platform is merely an alternative offered by the Exchange.

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 change will not 
impose any burden on intramarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act because the 
proposed rule change will apply to similarly situated participants 
uniformly, as described in detail above.
    The Exchange does not believe that the proposed rule changes will 
impose any burden on intermarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act because the 
proposed change applies only to Cboe Options. Additionally, the Legacy 
Platforms are similar to types of products that are widely available 
throughout the industry, including from some exchanges and the current 
version of Cboe Silexx and Silexx FLEX, at similar prices. Further, the 
proposed rule change relates to (i) an optional feature on an optional 
platform as it pertains to the proposed fee increase for the API for 
Legacy Platforms and (ii) further assisting participants in their 
migration efforts by waiving the Cboe Silexx Login ID fees for an 
additional month for this optional platform. As discussed, the use of 
the platform continues to be completely voluntary and market 
participants will continue to have the flexibility to use any entry and 
management tool that is proprietary or from third-party vendors, and/or 
market participants may choose any executing brokers to enter their 
orders. The Legacy Platforms are not an exclusive means of trading, and 
if market participants believe that other products, vendors, front-end 
builds, etc. available in the marketplace are more beneficial than the 
Legacy Platforms (or the current version of Cboe Silexx and Silexx 
FLEX), they may simply use those products instead, including for 
routing orders to the Exchange (indirectly or directly if they are 
authorized Users). Use of the functionality is completely voluntary.

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.
