SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-103967; File No. SR-MEMX-2025-28]


Self-Regulatory Organizations; MEMX LLC; Notice of Filing and 
Immediate Effectiveness of a Proposed Rule Change To Amend the 
Exchange's Fee Schedule Concerning Equities Transaction Pricing

September 15, 2025.
    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 September 8, 2025, MEMX LLC (``MEMX'' or the ``Exchange'') 
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.
---------------------------------------------------------------------------

    \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 the Exchange's fee schedule applicable to Members \3\ (the 
``Fee Schedule'') pursuant to Exchange Rules 15.1(a) and (c). As is 
further described below, the Exchange proposes to (i) modify the 
required criteria under Liquidity Provision Tiers 1 and 2; and (ii) 
adopt a new Tape B Volume Tier. The Exchange proposes to implement the 
changes to the Fee Schedule pursuant to this proposal immediately. The 
text of the proposed rule change is provided in Exhibit 5.
---------------------------------------------------------------------------

    \3\ See Exchange Rule 1.5(p).
---------------------------------------------------------------------------

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 amend the Fee 
Schedule to: (i) modify the required criteria under Liquidity Provision 
Tiers 1 and 2; and (ii) adopt a new Tape B Volume Tier, each as further 
described below.\4\
---------------------------------------------------------------------------

    \4\ The Exchange initially filed the proposed Fee Schedule 
changes on August 29, 2025 (SR-MEMX-2025-27). On September 8, 2025, 
the Exchange withdrew that filing and submitted this proposal.
---------------------------------------------------------------------------

    The Exchange first notes that it operates in a highly competitive 
market in which market participants can readily direct order flow to 
competing venues if they deem fee levels at a particular venue to be 
excessive or incentives to be insufficient. More specifically, the 
Exchange is only one of 18 registered equities exchanges, as well as a 
number of alternative trading systems and other off-exchange venues, to 
which market participants may direct their order flow. Based on 
publicly available information, no single registered equities exchange 
currently has more than approximately 14% of the total market share of 
executed volume of equities trading.\5\ Thus, in such a low-
concentrated and highly competitive market, no single equities exchange 
possesses significant pricing power in the execution of order flow, and 
the Exchange currently represents approximately 2% of the overall 
market share.\6\ The Exchange in particular operates a ``Maker-Taker'' 
model whereby it provides rebates to Members that add liquidity to the 
Exchange and charges fees to Members that remove liquidity from the 
Exchange. The Fee Schedule sets forth the standard rebates and fees 
applied per share for orders that add and remove liquidity, 
respectively. Additionally, in response to the competitive environment, 
the Exchange also offers tiered pricing, which provides Members with 
opportunities to qualify for higher rebates or lower fees where certain 
volume criteria and thresholds are met.

[[Page 45060]]

Tiered pricing provides an incremental incentive for Members to strive 
for higher tier levels, which provides increasingly higher benefits or 
discounts for satisfying increasingly more stringent criteria.

The Exchange receives and processes data made available through

    \6\ Id.
---------------------------------------------------------------------------

Liquidity Provision Tiers
    The Exchange currently provides a base rebate of $0.0015 per share 
for executions of displayed orders in securities priced at or above 
$1.00 per share that add liquidity to the Exchange (such orders, 
``Added Displayed Volume'').\7\ The Exchange also currently offers 
Liquidity Provision Tiers 1-5 under which a Member may receive an 
enhanced rebate for executions of Added Displayed Volume by achieving 
the corresponding required volume criteria for each such tier. The 
Exchange now proposes to modify the Liquidity Provision Tiers by 
modifying the required criteria under Liquidity Provision Tiers 1 and 
2, as further described below.
---------------------------------------------------------------------------

    \7\ The base rebate for executions of Added Displayed Volume is 
referred to by the Exchange on the Fee Schedule under the existing 
description ``Added non-displayed volume'' with a Fee Code of ``B'', 
``D'' or ``J'', as applicable, on execution reports.
---------------------------------------------------------------------------

    First with respect to Liquidity Provision Tier 1, the Exchange 
currently provides an enhanced rebate of $0.0033 a share for executions 
of Added Displayed Volume for Members that qualify for such tier by 
achieving: (1) an ADAV \8\ (excluding Retail Orders) that is equal to 
or greater than 0.40% of the TCV; \9\ or (2) an ADAV that is equal to 
or greater than 0.30% of the TCV in securities priced at or above $1.00 
per share and a Non-Displayed ADAV \10\ that is equal to or greater 
than 6,000,000 shares.\11\ The Exchange is now proposing to modify the 
criteria under Liquidity Provision Tier 1 by keeping the first criteria 
(1) intact with no changes but deleting the alternative criteria (2). 
The Exchange is not proposing to change the rebate provided under such 
tier.
---------------------------------------------------------------------------

    \8\ As set forth on the Fee Schedule, ``ADAV'' means the average 
daily added volume calculated as the number of shares added per day, 
which is calculated on a monthly basis, and ``Displayed ADAV'' means 
ADAV with respect to displayed orders.
    \9\ As set forth on the Fee Schedule, ``TCV'' means total 
consolidated volume calculated as the volume reported by all 
exchanges and trade reporting facilities to a consolidated 
transaction reporting plan for the month for which the fees apply.
    \10\ As set forth on the Fee Schedule, ``Non-Displayed ADAV'' 
means ADAV with respect to non-displayed orders (including orders 
subject to Display-Price Sliding that receive price improvement when 
executed and Midpoint Peg orders).
    \11\ The pricing for Liquidity Provision Tier 1 is referred to 
by the Exchange on the Fee Schedule under the existing description 
``Added displayed volume, Liquidity Provision Tier 1'' with a Fee 
Code of ``B1'', ``D1'' or ``J1'', as applicable, to be provided by 
the Exchange on the monthly invoices provided to Members.
---------------------------------------------------------------------------

    With respect to Liquidity Provision Tier 2, the Exchange currently 
provides an enhanced rebate of $0.0031 per share for executions of 
Added Displayed Volume under such tier by achieving: (1) an ADAV that 
is equal to or greater than 0.20% of the TCV and an ADV \12\ that is 
greater than or equal to 0.50% of the TCV; or (2) an ADAV that is equal 
to or greater than 0.20% of the TCV in securities priced at or above 
$1.00 per share and a Non-Displayed ADAV that is greater than or equal 
to 6,000,000 shares.\13\ Now, the Exchange proposes to modify the 
required criteria such that a Member would now qualify for Liquidity 
Provision Tier 2 by achieving: (1) an ADAV that is equal to or greater 
than 0.20% of the TCV and an ADV that is greater than or equal to 0.50% 
of the TCV; or (2) an ADAV that is equal to or greater than 0.20% of 
the TCV in securities priced at or above $1.00 per share and a Non-
Displayed ADAV that is greater than or equal to 6,000,000 shares; or 
(3) an ADAV that is equal to or greater than 0.10% of the TCV and a 
Step-Up ADAV \14\ that is equal to or greater then 0.05% of the TCV 
from August 2025. Thus, such proposed change keeps the first two 
alternative criteria intact with no changes but adds a third 
alternative criteria that includes both an ADAV requirement and a Step-
Up ADAV requirement using August 2025 as the baseline month. Given 
this, the Exchange is also proposing that the newly proposed criteria 
(3) of Liquidity Provision Tier 2 will expire no later than February 
28, 2026, which it will indicate in a note under the Liquidity 
Provision Tiers pricing table on the Fee Schedule. The Exchange is not 
proposing to change the rebate provided under such tier.
---------------------------------------------------------------------------

    \12\ As set forth on the Fee Schedule, ``ADV'' means average 
daily volume calculated as the number of shares added or removed, 
combined, per day. ADV is calculated on a monthly basis.
    \13\ The proposed pricing for Liquidity Provision Tier 2 is 
referred to by the Exchange on the Fee Schedule under the existing 
description ``Added displayed volume, Liquidity Provision Tier 2'' 
with a Fee Code of ``B2'', ``D2'' or ``J2'', as applicable, to be 
provided by the Exchange on the monthly invoices provided to 
Members.
    \14\ As set forth on the Fee Schedule, ``Step-Up ADAV'' means 
ADAV in the relevant baseline month subtracted from the current 
ADAV.
---------------------------------------------------------------------------

    The tiered pricing structure for executions of Added Displayed 
Volume under the Liquidity Provision Tiers provides an incremental 
incentive for Members to strive for higher volume thresholds to receive 
higher enhanced rebates for such executions and, as such, is intended 
to encourage Members to maintain or increase their order flow, 
primarily in the form of liquidity-adding volume, to the Exchange, 
thereby contributing to a deeper and more liquid market to the benefit 
of all Members and market participants. The Exchange believes that the 
Liquidity Provision Tiers, as modified by the proposed changes 
described above, reflect a reasonable and competitive pricing structure 
that is right-sized and consistent with the Exchange's overall pricing 
philosophy of encouraging added and/or displayed liquidity. 
Specifically, the Exchange believes that, after giving effect to the 
proposed changes described above, the rebate for executions of Added 
Displayed Volume provided under each of the Liquidity Provision Tiers 
1-5 remains commensurate with the corresponding required criteria under 
each such tier and is reasonably related to the market quality benefits 
that each such tier is designed to achieve.
New Tape B Volume Tier
    The Exchange currently offers the Tape B Volume Tier under which 
qualifying Members may receive an additive rebate of $0.0002 per share 
for executions of Added Displayed Volume (excluding Retail orders) in 
Tape B securities (such orders, ``Tape B Volume'') by achieving certain 
volume criteria. The additive rebate is provided in addition to the 
rebate that is otherwise applicable to each of a qualifying Members' 
executions that constitutes Tape B Volume (including a rebate provided 
under another pricing tier/incentive). The Exchange now proposes to 
adopt a new tier under the Tape B Volume Tiers, which as proposed, 
would be the new Tape B Volume Tier 1, and the existing Tape B Volume 
Tier would be renamed Tape B Volume Tier 2 (hereinafter referred to as 
such). The additive rebate and required criteria under the renamed Tape 
B Volume Tier 2 would remain unchanged.
    Under the proposed new Tape B Volume Tier 1, the Exchange would 
provide an additive rebate of $0.0005 per share for executions of Tape 
B Volume for Members that qualify for such tier by achieving: (1) a 
Tape B ADAV that is equal to or greater than 0.40% of the Tape B TCV 
(excluding Retail Orders); and (2) a Non-Display ADAV that is equal to 
or greater than 8,000,000 shares.\15\
---------------------------------------------------------------------------

    \15\ The proposed pricing for the Tape B Volume Tier 1 is 
referred to by the Exchange on the Fee Schedule under the 
description ``Tape B Volume Tier 1'' with a Fee Code of ``b1'' to be 
appended to the otherwise applicable Fee Code assigned by the 
Exchange on the monthly invoices for qualifying executions. The new 
Tape B Volume Tier 2 (previously named Tape B Volume Tier) will be 
referred to under the description ``Tape B Volume Tier 2'' with a 
Fee Code of ``b2'' to be appended to the otherwise applicable Fee 
Code assigned by the Exchange on the monthly invoices for qualifying 
executions.

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

[[Page 45061]]

    The Tape B Volume Tiers are designed to attract displayed liquidity 
to the Exchange in Tape B securities by providing an additive rebate 
for executions of Tape B Volume to Members, thereby promoting price 
discovery and market quality on the Exchange. The Exchange notes that 
the proposed additive rebate under the newly proposed Tape B Volume 
Tier 1 is commensurate with the corresponding required criteria under 
each such tier and is reasonably related to the market quality benefits 
that the tier is designed to achieve.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with the provisions of Section 6 of the Act,\16\ in general, and with 
Sections 6(b)(4) and 6(b)(5) of the Act,\17\ in particular, in that it 
provides for the equitable allocation of reasonable dues, fees and 
other charges among its Members and other persons using its facilities 
and is not designed to permit unfair discrimination between customers, 
issuers, brokers, or dealers.

    \17\ 15 U.S.C. 78f(b)(4) and (5).
---------------------------------------------------------------------------

    As discussed above, the Exchange operates in a highly fragmented 
and competitive market in which market participants can readily direct 
order flow to competing venues if they deem fee levels at a particular 
venue to be excessive or incentives to be insufficient, and the 
Exchange represents only a small percentage of the overall market. The 
Commission and the courts have repeatedly expressed their preference 
for competition over regulatory intervention in determining prices, 
products, and services in the securities markets. In Regulation NMS, 
the Commission highlighted the importance of market forces in 
determining prices and SRO revenues and also recognized that current 
regulation of the market system ``has been remarkably successful in 
promoting market competition in its broader forms that are most 
important to investors and listed companies.'' \18\
---------------------------------------------------------------------------

    \18\ Securities Exchange Act Release No. 51808 (June 9, 2005), 
70 FR 37496, 37499 (June 29, 2005).
---------------------------------------------------------------------------

    The Exchange believes that the ever-shifting market share among the 
exchanges from month to month demonstrates that market participants can 
shift order flow or discontinue use of certain categories of products, 
in response to new or different pricing structures being introduced 
into the market. Accordingly, competitive forces constrain the 
Exchange's transaction fees and rebates, and market participants can 
readily trade on competing venues if they deem pricing levels at those 
other venues to be more favorable. The Exchange believes the proposal 
reflects a reasonable and competitive pricing structure designed to 
incentivize market participants to direct additional order flow, 
including displayed liquidity-adding orders to the Exchange, which the 
Exchange believes would promote price discovery and enhance liquidity 
and market quality on the Exchange to the benefit of all Members and 
market participants.
    The Exchange notes that volume and quoting-based incentives (such 
as tiers) have been widely adopted by exchanges, including the 
Exchange, and are reasonable, equitable and not unfairly discriminatory 
because they are open to all members on an equal basis and provide 
additional benefits that are reasonably related to the value to an 
exchange's market quality associated with higher levels of market 
activity, such as higher levels of liquidity provision and/or growth 
patterns, and the introduction of higher volumes of orders into the 
price and volume discovery process. The Exchange believes that the 
Liquidity Provision Tiers 1 and 2, each as modified by the proposed 
changes to the required criteria under such tier, and the newly 
proposed Tape B Volume Tier 1, are reasonable, equitable and not 
unfairly discriminatory for these same reasons, as such tiers would 
continue to provide Members with an incremental incentive to achieve 
certain volume thresholds on the Exchange, are available to all Members 
on an equal basis, and, as described above, are designed to encourage 
Members to maintain or increase their order flow, including in the form 
of displayed, liquidity-adding, orders to the Exchange in both all 
securities and a smaller subset of securities (i.e., Tape B securities) 
in order to qualify for an enhanced rebate for executions of Added 
Displayed Volume or Tape B Volume, as applicable, thereby contributing 
to a deeper, more liquid and well balanced market ecosystem on the 
Exchange to the benefit of all Members and market participants. The 
Exchange also believes that the proposed changes to such tiers reflect 
a reasonable and equitable allocation of fees and rebates, because, as 
noted above, the Exchange believes in each case that the rebates under 
the Liquidity Provision Tiers and the new additive rebate under Tape B 
Volume Tier 1 remain commensurate with the corresponding required 
criteria under such tiers, and are reasonably related to the market 
quality benefits that each tier is designed to achieve.
    For the reasons discussed above, the Exchange submits that the 
proposal satisfies the requirements of Sections 6(b)(4) and 6(b)(5) of 
the Act \19\ in that it provides for the equitable allocation of 
reasonable dues, fees and other charges among its Members and other 
persons using its facilities and is not designed to unfairly 
discriminate between customers, issuers, brokers, or dealers. As 
described more fully below in the Exchange's statement regarding the 
burden on competition, the Exchange believes that its transaction 
pricing is subject to significant competitive forces, and that the 
proposed rebates described herein are appropriate to address such 
forces.
---------------------------------------------------------------------------

    \19\ 15 U.S.C. 78f(b)(4) and (5).
---------------------------------------------------------------------------

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposal will result in any 
burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. Instead, as discussed above, 
the proposal is intended to incentivize market participants to direct 
additional order flow to the Exchange, thereby enhancing liquidity and 
market quality on the Exchange to the benefit of all Members and market 
participants. As a result, the Exchange believes the proposal would 
enhance its competitiveness as a market that attracts actionable 
orders, thereby making it a more desirable destination venue for its 
customers. For these reasons, the Exchange believes that the proposal 
furthers the Commission's goal in adopting Regulation NMS of fostering 
competition among orders, which promotes ``more efficient pricing of 
individual stocks for all types of orders, large and small.'' \20\
---------------------------------------------------------------------------

    \20\ See supra note 18.
---------------------------------------------------------------------------

Intramarket Competition
    As discussed above, the Exchange believes that the proposal would 
incentivize Members to submit additional order flow, including 
displayed, liquidity-adding orders to the Exchange, thereby enhancing 
liquidity and market quality on the Exchange to the benefit of all 
Members, as well as enhancing the attractiveness of the Exchange as a 
trading venue, which the Exchange believes, in turn, would continue to 
encourage market participants to direct additional order

[[Page 45062]]

flow to the Exchange. Greater liquidity benefits all Members by 
providing more trading opportunities and encourages Members to send 
additional orders to the Exchange, thereby contributing to robust 
levels of liquidity, which benefits all market participants. The 
opportunity to qualify for the proposed modified Liquidity Provision 
Tiers 1 and 2, and thus receive the proposed enhanced rebate for 
executions of Added Displayed Volume under such tiers, and the 
opportunity to qualify for the newly proposed Tape B Volume Tier 1 and 
thus receive the proposed additive rebate for executions of Tape B 
Volume, would be available to all Members that meet the associated 
volume requirements in any month. For the foregoing reasons, the 
Exchange believes the proposed changes would not impose any burden on 
intramarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act.
Intermarket Competition
    As noted above, the Exchange operates in a highly competitive 
market in which market participants can readily direct order flow to 
competing venues if they deem fee levels at a particular venue to be 
excessive or incentives to be insufficient. Members have numerous 
alternative venues that they may participate on and direct their order 
flow to, including 17 other equities exchanges and numerous alternative 
trading systems and other off-exchange venues. As noted above, no 
single registered equities exchange currently has more than 
approximately 14% of the total market share of executed volume of 
equities trading. Thus, in such a low-concentrated and highly 
competitive market, no single equities exchange possesses significant 
pricing power in the execution of order flow. Moreover, the Exchange 
believes that the ever-shifting market share among the exchanges from 
month to month demonstrates that market participants can shift order 
flow or reduce use of certain categories of products, in response to 
new or different pricing structures being introduced into the market. 
Accordingly, competitive forces constrain the Exchange's transaction 
fees and rebates, including with respect to Added Displayed Volume and 
Tape B Volume, and market participants can readily choose to send their 
orders to other exchange and off-exchange venues if they deem fee 
levels at those other venues to be more favorable. As described above, 
the proposed changes represent a competitive proposal through which the 
Exchange is seeking to generate additional revenue with respect to its 
transaction pricing and to encourage the submission of additional order 
flow to the Exchange through volume-based tiers, which have been widely 
adopted by exchanges, including the Exchange. Accordingly, the Exchange 
believes the proposal would not burden, but rather promote, intermarket 
competition by enabling it to better compete with other exchanges that 
offer similar pricing incentives to market participants.
    Additionally, the Commission has repeatedly expressed its 
preference for competition over regulatory intervention in determining 
prices, products, and services in the securities markets. Specifically, 
in Regulation NMS, the Commission highlighted the importance of market 
forces in determining prices and SRO revenues and, also, recognized 
that current regulation of the market system ``has been remarkably 
successful in promoting market competition in its broader forms that 
are most important to investors and listed companies.'' \21\ The fact 
that this market is competitive has also long been recognized by the 
courts. In NetCoalition v. SEC, the D.C. Circuit stated as follows: 
``[n]o one disputes that competition for order flow is `fierce.' . . . 
As the SEC explained, `[i]n the U.S. national market system, buyers and 
sellers of securities, and the broker-dealers that act as their order-
routing agents, have a wide range of choices of where to route orders 
for execution'; [and] `no exchange can afford to take its market share 
percentages for granted' because `no exchange possesses a monopoly, 
regulatory or otherwise, in the execution of order flow from broker 
dealers'. . . .''.\22\ Accordingly, the Exchange does not believe its 
proposed pricing changes impose any burden on competition that is not 
necessary or appropriate in furtherance of the purposes of the Act.

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.
