[Release No. 34-103439; File No. SR-MEMX-2025-21]


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

July 11, 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 June 30, 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.

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) increase the fee 
for executions of Retail Orders in securities priced at or above $1.00 
per share that remove liquidity from the Exchange and (ii) modify the 
Liquidity Provision Tiers by reducing the rebate and modifying the 
required criteria under Liquidity Provision 2 and reducing the rebates 
under Liquidity Provision Tiers 3, 4, and 5. The Exchange proposes to 
implement the changes to the Fee Schedule pursuant to this proposal on 
July 1, 2025. 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

[[Page 32052]]

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) increase the fee for executions of Retail Orders \4\ 
in securities priced at or above $1.00 per share that remove liquidity 
from the Exchange (such orders, ``Removed Retail Volume''); and (ii) 
modify the Liquidity Provision Tiers by reducing the rebate and 
modifying the required criteria under Liquidity Provision 2 and 
reducing the rebates under Liquidity Provision Tiers 3, 4, and 5, each 
as further described below.
---------------------------------------------------------------------------

    \4\ A ``Retail Order'' means an agency or riskless principal 
order that meets the criteria of FINRA Rule 5320.03 that originates 
from a natural person and is submitted to the Exchange by a Retail 
Member Organization (``RMO''), provided that no change is made to 
the terms of the order with respect to price or side of market and 
the order does not originate from a trading algorithm or any other 
computerized methodology. See Exchange Rule 11.21(a).
---------------------------------------------------------------------------

    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 12.7% 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 2.2% 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. 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.

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

Increase Standard Fee for Removed Retail Volume
    Currently, the Exchange charges a standard fee of $0.0028 per share 
for executions of Removed Retail Volume. The Exchange now proposes to 
increase the standard fee for executions of Removed Retail Volume to 
$0.0030 per share.\7\ The purpose of increasing the standard fee for 
executions of Removed Retail Volume is for business and competitive 
reasons, as the Exchange believes that increasing such fee as proposed 
would generate additional revenue to offset some of the costs 
associated with the Exchange's current pricing structure, which 
provides various rebates for liquidity-adding orders, and the 
Exchange's operations generally, in a manner that is still consistent 
with the Exchange's overall pricing philosophy of encouraging added 
liquidity. The Exchange notes that despite the increase proposed 
herein, the proposed standard fee for executions of Removed Retail 
Volume remains in line with the standard fees charged by other 
exchanges for executions of Retail Orders in securities priced at or 
above $1.00 per share that remove liquidity.\8\
---------------------------------------------------------------------------

    \7\ The proposed standard fee for executions of Removed Retail 
Volume is referred to by the Exchange on the Fee Schedule under the 
existing description ``Removed volume from MEMX Book, Retail Order'' 
with a Fee Code of ``RrA'' on execution reports.
    \8\ See, e.g., the Cboe EDGX equities fee schedule on its public 
website (available at <a href="https://www.cboe.com/us/equities/membership/fee_schedule/edgx/">https://www.cboe.com/us/equities/membership/fee_schedule/edgx/</a>), which reflects a standard fee of $0.0030 per 
share for executions of Retail orders in securities priced at or 
above $1.00 per share that remove liquidity; the Cboe BZX equities 
fee schedule on its public website (available at <a href="https://www.cboe.com/us/equities/membership/fee_schedule/bzx/">https://www.cboe.com/us/equities/membership/fee_schedule/bzx/</a>) which 
reflects a standard fee of $0.0030 per share for executions of 
Retail orders in securities priced at or above $1.00 per share that 
remove liquidity.
---------------------------------------------------------------------------

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'').\9\ 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 reduce the rebate and modify the required 
criteria under Liquidity Provision Tier 2 and reduce the rebates under 
Liquidity Provision Tiers 3, 4, and 5, as further described below.
---------------------------------------------------------------------------

    \9\ 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 2, the Exchange 
currently provides an enhanced rebate of $0.0032 per share for 
executions of Added Displayed Volume for Members that qualify for such 
tier by achieving: (1) an ADAV \10\ that is equal to or greater than 
0.20% of the TCV \11\ and an ADV \12\ that is equal or greater than 
0.50% of the TCV; or (2) an ADAV that is equal to or greater than 0.30% 
of the TCV. The Exchange now proposes to reduce the rebate for 
executions of Added Displayed Volume under Liquidity Provision Tier 2 
to $0.0031 per share,\13\ and to modify the required criteria such that 
a Member would now qualify for such tier by achieving: (1) an ADAV that 
is equal to or greater than 0.20% of the TCV and an ADV that is equal 
to or greater than 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 equal to or greater than 
6,000,000 shares. Thus, such proposed change would keep the existing 
first alternative criteria intact and modify the second alternative 
criteria to include a reduced ADAV threshold in securities priced at or

[[Page 32053]]

above $1.00 per share and a Non-Displayed ADAV threshold. The Exchange 
is not proposing to change the rebate for executions of orders in 
securities priced below $1.00 per share under Liquidity Provision Tier 
2.
---------------------------------------------------------------------------

    \10\ 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.
    \11\ 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.
    \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.
---------------------------------------------------------------------------

    Second, with respect to Liquidity Provision Tier 3,\14\ the 
Exchange currently provides an enhanced rebate of $0.0030 per share for 
executions of Added Displayed Volume for Members that qualify for such 
tier by achieving: 1) an ADAV that is equal to or greater than 0.20% of 
the TCV in securities priced at or above $1.00 per share; or 2) an ADAV 
that is equal to or greater than 0.175% of the TCV. The Exchange now 
proposes to reduce the rebate for executions of Added Displayed Volume 
under Liquidity Provision Tier 3 to $0.0029 per share. The Exchange is 
not proposing to change the criteria required to qualify for Liquidity 
Provision Tier 3. The Exchange is also not proposing to change the 
rebate for executions of orders in securities priced below $1.00 per 
share under such tier.
---------------------------------------------------------------------------

    \14\ The pricing for Liquidity Provision Tier 3 is referred to 
by the Exchange on the Fee Schedule under the existing description 
``Added displayed volume, Liquidity Provision Tier 3'' with a Fee 
Code of ``B3'', ``D3'' or ``J3'', as applicable, to be provided by 
the Exchange on the monthly invoices provided to Members.
---------------------------------------------------------------------------

    Third, with respect to Liquidity Provision Tier 4,\15\ the Exchange 
currently provides an enhanced rebate of $0.0029 per share for 
executions of Added Displayed Volume for Members that qualify for such 
tier by achieving an ADAV (excluding Retail Orders) that is equal to or 
greater than 0.09% of the TCV. The Exchange now proposes to reduce the 
rebate for executions of Added Displayed Volume under Liquidity 
Provision Tier 4 to $0.0028 per share. The Exchange is not proposing to 
change the criteria required to qualify for Liquidity Provision Tier 4. 
The Exchange is also not proposing to change the rebate for executions 
of orders in securities priced below $1.00 per share under such tier.
---------------------------------------------------------------------------

    \15\ The pricing for Liquidity Provision Tier 4 is referred to 
by the Exchange on the Fee Schedule under the existing description 
``Added displayed volume, Liquidity Provision Tier 4'' with a Fee 
Code of ``B4'', ``D4'' or ``J4'', as applicable, to be provided by 
the Exchange on the monthly invoices provided to Members.
---------------------------------------------------------------------------

    Lastly, with respect to Liquidity Provision Tier 5,\16\ the 
Exchange currently provides an enhanced rebate of $0.0025 per share for 
executions of Added Displayed Volume for Members that qualify for such 
tier by achieving an ADAV that is equal to or greater than 0.06% of the 
TCV. The Exchange now proposes to reduce the rebate for executions of 
Added Displayed Volume under Liquidity Provision Tier 5 to $0.0024 per 
share. The Exchange is not proposing to change the criteria required to 
qualify for Liquidity Provision Tier 5. The Exchange is also not 
proposing to change the rebate for executions of orders in securities 
priced below $1.00 per share under such tier.
---------------------------------------------------------------------------

    \16\ The pricing for Liquidity Provision Tier 5 is referred to 
by the Exchange on the Fee Schedule under the existing description 
``Added displayed volume, Liquidity Provision Tier 5'' with a Fee 
Code of ``B5'', ``D5'' or ``J5'', as applicable, to be provided by 
the Exchange on the monthly invoices provided to Members.
---------------------------------------------------------------------------

    The purpose of reducing the rebates for executions of Added 
Displayed Volume under Liquidity Provision Tiers 2, 3, 4, and 5 as 
proposed (i.e., by $0.0001 per share), which the Exchange believes is a 
modest reduction and remains commensurate with the required criteria, 
is for business and competitive reasons, as the Exchange believes that 
such reduction would decrease the Exchange's expenditures with respect 
to its transaction pricing in a manner that is still consistent with 
the Exchange's overall pricing philosophy of encouraging added 
liquidity.
    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.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with the provisions of Section 6 of the Act,\17\ in general, and with 
Sections 6(b)(4) and 6(b)(5) of the Act,\18\ 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.

    \18\ 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.'' \19\
---------------------------------------------------------------------------

    \19\ 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 and/or liquidity removing 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 believes that the proposed change to increase the 
standard fee charged for executions Removed Retail Volume is reasonable 
because it represents only a modest increase from the current standard 
fee charged for executions of Removed

[[Page 32054]]

Retail Volume and, as noted above, remains in line with the standard 
fees charged by other executions of Retail orders in securities priced 
at or above $1.00 per share that remove liquidity.\20\ The Exchange 
also believes the proposed standard fee charged for executions of 
Removed Retail Volume is equitable and not unfairly discriminatory, as 
such fee will apply equally to all Members submitting Retail Orders to 
the Exchange.
---------------------------------------------------------------------------

    \20\ See supra note 8.
---------------------------------------------------------------------------

    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 2, 3, 4, and 5, as modified by the proposed 
changes to the rebates and criteria, as applicable, 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 order to qualify for an enhanced rebate for executions 
of Added Displayed Volume, 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 proposed new rebate 
represents a modest reduction, as applicable, remains commensurate with 
the corresponding required criteria under such tier, and is reasonably 
related to the market quality benefits that the tier is designed to 
achieve, as described above.
    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 \21\ 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 additive rebate described herein is appropriate to address 
such forces.
---------------------------------------------------------------------------

    \21\ 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.'' \22\
---------------------------------------------------------------------------

    \22\ See supra note 19.
---------------------------------------------------------------------------

Intramarket Competition
    As discussed above, the Exchange believes that the proposal would 
incentivize Members to submit additional order flow, including 
displayed, liquidity-adding and/or removing 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 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 2, 3, 4, and 5, and thus receive the proposed enhanced rebate for 
executions of Added Displayed Volume under such tiers, would be 
available to all Members that meet the associated volume requirements 
in any month. Additionally, as noted above, the proposed increased 
standard fee for executions of Removed Retail Volume would continue to 
apply equally to all Members in the same manner that such standard fees 
currently do today. 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 12.7% 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 
Removed Retail 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.

[[Page 32055]]

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.'' \23\ 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' . . . .''.\24\ 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.
