[[Page 61902]]

``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on September 15, 2026, MX2 LLC (``MX2'' or the ``Exchange'') filed with 
the Securities and Exchange Commission (the ``Commission'') the 
proposed rule change as described in Items I and II 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.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 78s(b)(1).
    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    The Exchange is filing with the Commission a proposed rule change 
to amend Rule 16.1, (Definitions) to establish a monthly review of 
Professional Orders.\3\ The text of the proposed rule change is 
provided in Exhibit 5 and is available on the Exchange's website at 
<a href="https://info.memxtrading.com/regulation/rules-and-filings/">https://info.memxtrading.com/regulation/rules-and-filings/</a>.
---------------------------------------------------------------------------

    \3\ See Exchange Rule 16.1. The term ``Professional'' means any 
person or entity that (A) is not a broker or dealer in securities; 
and (B) places more than 390 orders in listed options per day on 
average during a calendar month for its own beneficial account(s). 
All Professional orders shall be appropriately marked by Options 
Members.
---------------------------------------------------------------------------

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 Rule 16.1 (Definitions) to establish 
a monthly review of Professional orders. This filing is based on a 
proposal recently submitted by Nasdaq ISE, LLC (``ISE'').\4\
---------------------------------------------------------------------------

    \4\ See Securities Exchange Act No. 105218 (April 13, 2026) 91 
FR 20542 (April 16, 2026) (SR-ISE-2026-16) (Notice of Filing and 
Immediate Effectiveness of Proposed Rule Change to Amend the Review 
of Professional Orders.)
---------------------------------------------------------------------------

    Today, per the definition of Professional under Rule 16.1, orders 
for any Public Customer \5\ that averages more than 390 orders per day 
during any month must be represented as Professional orders. 
Historically, the requirement to review for accurate order marking was 
done on a quarterly basis,\6\ however, other exchanges, including ISE 
and the Exchange's affiliate, MEMX Options, have recently amended their 
rules to a monthly review.\7\ In light of the recent launch of MX2 
Options,\8\ the Exchange wishes to codify the timing of its Members' 
\9\ review of Public Customers' activities in the rule in order to 
align with the rules of these other exchanges. Specifically, the 
Exchange wishes to amend its rule such that Members are required to 
review their Public Customers' activity and designate orders as Public 
Customer Orders or Professional orders on a monthly basis.
---------------------------------------------------------------------------

    \5\ See Exchange Rule 16.1. A ``Public Customer'' means a person 
that is not a broker or dealer in securities.
    \6\ The requirement to review Public Customers' activity on at 
least a quarterly basis to determine whether orders that are not for 
the account of a broker-dealer should be represented as Public 
Customer Orders or Professional Orders is not in the current rule 
text, however it was an industry requirement and was described in 
the adopting proposals filed by the other options exchanges. See, 
e.g., Securities Exchange Act Release Nos. 77853 (May 19, 2016), 81 
FR 33301 (May 25, 2016) (SR-MIAX-2016-11) (Notice of Filing and 
Immediate Effectiveness of Proposed Rule Change to Amend Exchange 
Rule 100 Concerning Professional Customers); 78788 (September 8, 
2016), 81 FR 63252 (September 14, 2016) (SR-ISE-2016-19) (Notice of 
Filing and Immediate Effectiveness of Proposed Rule Change to Add 
Specificity to the Definition of a Professional in the Exchange's 
Rules); 77054 (February 4, 2016), 81 FR 7166 (February 10, 2016) 
(SR-Phlx-2016-10) (Notice of Filing of Proposed Rule Change Relating 
to Professional Customer Definition). The instant proposal seeks to 
codify the timing for review of Public Customers' activities in 
advance of the launch of MX2 Options.
    \7\ See Securities Exchange Act Release No. 105878 (July 10, 
2026), 91 FR 43442 (July 15, 2026) (SR-MEMX-2026-20).
    \8\ MX2 Options launched on September 14, 2026. See: <a href="https://memx.com/insights/september-2026-go-live-date-for-mx2-options">https://memx.com/insights/september-2026-go-live-date-for-mx2-options</a>.
    \9\ See Exchange Rule 1.5(p). The term ``Member'' means any 
registered broker or dealer that has been admitted to membership in 
the Exchange.
---------------------------------------------------------------------------

    In doing so, the Exchange proposes to state under the definition of 
``Professional'' in Rule 16.1 that orders for any customer that had an 
average of more than 390 orders per day during any calendar month must 
be represented as Professional orders for the next calendar month.
    As noted, current industry practice requires market participants to 
monitor Public Customer Orders to determine if the Public Customer has 
averaged more than 390 orders per day during a month. Determining 
whether a Public Customer has executed more than 390 orders per day 
during a month requires computing a daily average. As such, market 
participants should be performing the workflow necessary to designate 
orders on a daily basis. Therefore, the proposal will not require 
market participants to change current workflow, rather, the proposal 
establishes a specific timeframe in the Exchange's rules to change the 
manner in which the customer's order is being represented five days 
after the end of each calendar month.
    The Exchange does not believe that this amendment is a significant 
departure from the current rule, nor will it impose any burden on any 
Member because each broker-dealer is required currently to perform the 
necessary calculation daily to arrive at the requisite average, and 
other exchanges have adopted the same requirement, including the 
Exchange's affiliate, MEMX Options.\10\ Further, in addition to the 
calculation, broker-dealers are subject to know-your-customer and 
suitability requirements under FINRA Rules 2090 (Know Your Customer) 
and 2111 (Suitability) and would need to consider whether a customer 
meets the Professional designation for purposes of determining best 
execution and making appropriate recommendations. Finally, it is the 
Exchange's understanding that on other exchanges, some market 
participants currently designate a Public Customer that has averaged 
more than 390 orders per day during a month as a Professional on a more 
expedited basis, not waiting until five days after the quarter.
---------------------------------------------------------------------------

    \10\ See supra note 9.
---------------------------------------------------------------------------

    The Exchange notes that the trading behavior of a Public Customer 
can be distinguished from that of a Professional which is the purpose 
of the separate designations. The Exchange believes that identifying 
Professional orders based upon the average number of orders entered in 
qualified accounts is an appropriately objective approach to reasonably 
distinguish such persons and entities from retail investors or market 
participants.
2. Statutory Basis
    The Exchange believes the proposal is consistent with the Act and 
the rules and regulations thereunder applicable to the Exchange and, in 
particular, the requirements of Section 6(b) of the Act.\11\ 
Specifically, the Exchange believes the proposed rule change is 
consistent with the Section 6(b)(5) \12\ requirements that the rules of 
an exchange be designed to prevent

[[Page 61903]]

fraudulent and manipulative acts and practices, to promote just and 
equitable principles of trade, to foster cooperation and coordination 
with persons engaged in 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.
---------------------------------------------------------------------------

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

    In particular, the Exchange's proposal to codify and establish a 
monthly look-back is consistent with the Act because it will ensure 
that its rules align with those of other options exchanges. Further, 
the Exchange believes that the codified time period will promote 
consistency in the treatment of orders as Professional orders while 
also preventing Members with high volume from receiving benefits 
reserved for Public Customer Orders.
    As noted, current industry practice requires market participants to 
monitor Public Customer Orders to determine if the Public Customer has 
averaged more than 390 orders per day during a month. Determining 
whether a Public Customer has executed more than 390 orders per day 
during a month requires computing a daily average. As such, 
participants should be performing the workflow necessary to designate 
orders on a daily basis. Therefore, the proposal does not amend the 
current workflow, rather, the proposal establishes a specific timeframe 
to change the manner in which the customer's order is being represented 
five days after the end of each calendar month.
    The Exchange does not believe that this amendment is a significant 
departure from the current rule, nor does it impose any burden on any 
Member because each broker-dealer is required currently to perform the 
necessary calculation daily to arrive at the requisite average. 
Further, in addition to the calculation, broker-dealers are subject to 
know-your-customer and suitability requirements under FINRA Rules 2090 
(Know Your Customer) and 2111 (Suitability) and would need to consider 
whether a customer meets the Professional designation for purposes of 
determining best execution and making appropriate recommendations. 
Finally, it is the Exchange's understanding that on other exchanges, 
some market participants currently designate a Public Customer that has 
averaged more than 390 orders per day during a month as a Professional 
on a more expedited basis, not waiting until five days after the 
quarter.
    The Exchange notes that the trading behavior of a Public Customer 
can be distinguished from that of a Professional which is the purpose 
of the separate designations. The Exchange continues to believe that 
identifying Professional orders based upon the average number of orders 
entered in qualified accounts is an appropriately objective approach to 
reasonably distinguish such persons and entities from retail investors 
or market participants. Priority is one of the marketplace advantages 
provided to Public Customer orders on the Exchange. Priority Customer 
Orders \13\ are given execution priority over non-Customer orders and 
quotations of market makers at the same price. Another marketplace 
advantage afforded to Priority Customer orders on the Exchange is that 
Members are generally not assessed transaction fees for the execution 
of Priority Customer orders. The purpose of these marketplace 
advantages is to attract retail order flow to the Exchange by leveling 
the playing field for retail investors over market Professionals. This 
proposal will continue to provide Priority Customer accounts with 
marketplace advantages and distinguish the accounts of non-Professional 
retail investors from Professional accounts. The Exchange notes that 
some non-broker-dealer individuals and entities have access to 
information and technology that enables them to Professionally trade 
listed options in the same manner as a broker or dealer in securities.
---------------------------------------------------------------------------

    \13\ The term ``Priority Customer'' means any person or entity 
that is not: (A) a broker or dealer in securities; or (B) a 
Professional. The term ``Priority Customer Order'' means an order 
for the account of a Priority Customer. See Rule 16.1.
---------------------------------------------------------------------------

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. In this regard and as 
indicated above, the Exchange notes that the rule change is 
substantially similar to a filing recently submitted by ISE and the 
Exchange's affiliate, MEMX Options.\14\
---------------------------------------------------------------------------

    \14\ See supra notes 6 and 9.
---------------------------------------------------------------------------

    Specifically, the Exchange does not believe that the proposed rule 
change will impose any burden on intra-market competition because 
market participants have begun the monthly lookback on other exchanges, 
and the proposal does not amend the current workflow, rather, it 
establishes a timeframe to change the manner in which the customer's 
order is being represented to five days at the end of each calendar 
month.
    Further, the designation of Professional orders would not result in 
any different treatment of such orders for purposes of compliance with 
the Exchange's Rules. Priority Customers have been granted certain 
priority over other non-broker-dealer individuals and entities that 
have access to information and technology that enables them to 
Professionally trade listed options in the same manner as a broker or 
dealer in securities. Further, the Priority Customer designation allows 
the Exchange to attract order flow or create more competitive markets.
    Also, the Exchange does not believe that the proposed rule change 
will impose any burden on inter-market competition because other 
exchanges have adopted the same rule, and this proposal is being 
submitted in order to align MX2's rulebook with other exchanges, 
including its affiliate, MEMX Options.\15\

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

    Because the foregoing proposed rule change does not: (i) 
significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days from the date on which it was filed, or 
such shorter time as the Commission may designate, it has become 
effective pursuant to Section 19(b)(3)(A)(iii) of the Act \16\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\17\
---------------------------------------------------------------------------

    \16\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \17\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6)(iii) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change, along 
with a brief description and text of the proposed rule change, at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \18\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b-4(f)(6)(iii),\19\ the Commission 
may designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange requested 
that the Commission waive the 30-day operative delay so that the 
proposal may become operative immediately upon

[[Page 61904]]

filing. The Exchange states that waiver of the operative delay would 
allow the Exchange to immediately adopt new language to establish a 
monthly review for Members to determine whether the activity of a 
customer meets the criteria for the orders to be designated as 
Professional Orders upon launch of MX2 Options. Furthermore, the 
proposed rule change raises no new or novel legal or regulatory issues. 
For these reasons, the Commission finds that waiver of the operative 
delay is consistent with the protection of investors and the public 
interest. Accordingly, the Commission waives the 30-day operative delay 
and designates the proposed rule change to be operative upon 
filing.\20\
---------------------------------------------------------------------------

    \18\ 17 CFR 240.19b-4(f)(6).
    \19\ 17 CFR 240.19b-4(f)(6)(iii).
    \20\ For purposes only of waiving the 30-day operative delay, 
the Commission has considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    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.
