###### Securities and Exchange Commission

          - [Release No. 34-90943; File No. SR-CboeBYX-2021-004]

                    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 January 13, 2021, Cboe BYX Exchange, Inc. (the “Exchange” or “BYX”) 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.                

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

Cboe BYX Exchange, Inc. (the “Exchange” or “BYX Equities”) proposes to amend its fee schedule to establish a fee in connection with a Member's Market Participant Identifier(s) (“MPID”). 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 (                    *http://markets.cboe.com/​us/​equities/​regulation/​rule_​filings/​byx/​*), 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 its Fee Schedule to adopt a monthly fee assessed on Members' MPIDs.[3] 

                    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 16 registered equities exchanges, as well as a number of alternative trading systems and other off-exchange venues that do not have similar self-regulatory responsibilities under the Exchange Act, to which market participants may direct their order flow. Based on publicly available information,[4]                                          no single registered equities exchange has more than 16% of consolidated equity market share and currently the Exchange represents approximately 1.5% of the U.S. equities market. Thus, in such a low-concentrated and highly competitive market, no single equities exchange possesses significant pricing power in the execution of order flow. The Exchange further notes that broker-dealers are not compelled to be Members of the Exchange, and a significant proportion of broker-dealers that trade U.S. equity securities have, in fact, chosen not to apply for membership on the Exchange.                

                    By way of background, an MPID is a four-character unique identifier that is approved by the Exchange and assigned to a Member for use on the Exchange to identify the Member firm on the orders sent to the Exchange and resulting executions. Members may choose to request more than one MPID as a unique identifier(s) for their transactions on the Exchange. The Exchange notes that a Member may have multiple MPIDs for use by separate business units and trading desks or to support Sponsored Participant [5]                                          access. Certain members currently leverage multiple MPIDs to obtain benefits from and added value in their participation on the Exchange. Multiple MPIDs provide unique benefits to and efficiencies for Members by allowing: (1) Members to manage their trading activity more efficiently by assigning different MPIDs to different trading desks and/or strategies within the firm; and (2) Sponsoring Members [6]                                          to segregate Sponsored Participants by MPID to allow for detailed client-level reporting, billing, and administration, and to market the ability to use separate MPIDs to Sponsored Participants, which, in turn, may serve as a potential incentive for increased order flow traded through the Sponsoring Member.                

The Exchange proposes to adopt a fee applicable to Members that use multiple MPIDs to facilitate their trading on the Exchange. Specifically, as proposed, the Exchange would assess a monthly MPID Fee of $150 per MPID per Member, with a Member's first MPID provided free of charge. The Exchange believes the proposed assessment of an MPID Fee aligns with the additional value and benefits provided to Members that choose to utilize more than one MPID to facilitate their trading on the Exchange. The Exchange also believes that assessing a fee on additional MPIDs will be beneficial because such fee will promote efficiency in MPID use.

The MPID Fee will be assessed on a pro-rated basis for new MPIDs by charging a Member based on the trading day in the month during which an additional MPID becomes effective for use. If a Member cancels an additional MPID on or after the first business day of the month, the Member will be required to pay the entire MPID Fee for that month. The Exchange believes that this practice is appropriate to balance the administrative costs associated with disabling MPIDs.

#### 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                           ( print page 7147)                        and, in particular, the requirements of Section 6(b) of the Act.[7]                                          Specifically, the Exchange believes the proposed rule change is consistent with Section 6(b)(4) of the Act,[8]                                          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 also believes that the proposed rule change is consistent with the objectives of Section 6(b)(5) 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, and, particularly, is not designed to permit unfair discrimination between customers, issuers, brokers, or dealers.                

The Exchange believes that the proposed MPID Fee is consistent with the Act in that it is reasonable, equitable, and not unfairly discriminatory. In particular, the Exchange believes that the proposed fee is reasonable because it is reasonably aligned with the benefits provided to Members that choose to utilize multiple MPIDs to facilitate their trading on the Exchange. While each Member must have an MPID to participate on the Exchange, additional MPIDs are optional and will be assessed the proposed fee. Additional MPIDs currently allow for Members to realize certain benefits from and added value to their participation on the Exchange but also require the Exchange to allocate additional administrative resources to manage each MPID that a Member chooses to use for its trading activity. Therefore, the Exchange believes that it is reasonable to assess a modest fee on any additional MPIDs that Members choose to use to facilitate their trading. The Exchange again notes that it is optional for a Member to request and employ additional MPIDs, and a large portion (approximately 39%) of the Exchange's Members currently utilize just the one MPID necessary to participate on the Exchange.

                    The Exchange also believes that assessing a modest fee on additional MPIDs is reasonably designed to promote efficiency in MPID use. The Exchange notes that its affiliated equities exchanges, Cboe EDGX Exchange, Inc. (“EDGX”) and Cboe EDGA Exchange, Inc. (“EDGA”), had previously implemented an MPID Fee,[9]                                          and observed that, as a result of an MPID Fee, members were incentivized to more effectively administer their MPIDs and reduce the number of under-used or superfluous MPIDs, or MPIDs that did not contribute additional value to a member's participation on the exchange. Reduction of such MPIDs, in turn, reduces exchange resources allocated to administration and maintenance of those MPIDs. In particular, it was observed that within the first few months of introducing the previous MPID Fee on the Exchange's affiliated exchanges, the number of MPIDs on EDGX and EDGA each decreased by approximately 17%, demonstrating that Members may choose to be more efficient in their use of MPIDs in response to an MPID Fee, such as that proposed in this fee change.[10] 

                    The Exchange further believes the proposed MPID Fee is reasonable because the amount assessed is less than the analogous fees charged by at least one other market; namely, Nasdaq Stock Market LLC (“Nasdaq”).[11]                                          The Exchange's proposed MPID Fee at $150 a month per MPID, with no charge associated with a Members' first MPID, is lower than Nasdaq's MPID fee of $550 per MPID, which is charged for all MPIDs used by a Nasdaq member, including a member's first MPIDs. Additionally, the Exchange believes that charging a full-month's fee for an additional MPID cancelled on or after the first business day of the month is reasonable in that it reasonably accounts for the administrative costs associated with disabling such MPIDs, and is a practice consistent with Nasdaq's similar cancellation policy in connection with its MPID fees.[12] 

The Exchange believes that the proposed MPID Fee is equitable and not unfairly discriminatory because it will apply equally to all Members that choose to employ two or more MPIDs based on the number of additional MPIDs that they use to facilitate their trading on the Exchange. As stated, additional MPIDs beyond a Member's first MPID are optional, and Members may choose to trade using such additional MPIDs to achieve additional benefits and added value to support their individual business needs. Moreover, the Exchange believes the proposed fee is equitable and not unfairly discriminatory because it is proportional to the potential value or benefit received by Members with a greater number of MPIDs. That is, those Members that choose to employ a greater number of additional MPIDs have the opportunity to more effectively manage firm-wide trading activity and client-level administration, as well as potentially appeal to customers through the use of separate MPIDs, which may result in increased order flow through a Sponsoring Member. A Member may request at any time that the Exchange terminate an MPID, including MPIDs that may be under-used or superfluous, or that do not contribute additional value to a Member's participation on 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 intramarket competition that is not necessary in furtherance of the purposes of the Act because the proposed MPID Fee will apply equally to all Members that choose to employ additional MPIDs and equally to each additional MPID. As stated, additional MPIDs are optional and Members may choose to utilize additional MPIDs, or not, based on their view of the additional benefits and added value provided by utilizing the single MPID necessary to participate on the Exchange. The Exchange believes the proposed fee will be assessed proportionately to the potential value or benefit received by Members with a greater number of MPIDs and notes that a Member may request at any time that the Exchange terminate any MPID, including those that may be under-used or superfluous, or that do not contribute additional value to a Member's participation on the Exchange.

                    Next, the Exchange believes the proposed rule change does not impose any burden on intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act. As previously discussed, the Exchange operates in a highly competitive market, including competition for exchange memberships. Members have numerous                           ( print page 7148)                        alternative venues that they may participate on, including 15 other equities exchanges, as well as off-exchange venues, including over 50 alternative trading systems.[13]                                          The Exchange represents a small percentage of the overall market. Based on publicly available information, no single equities exchange has more than 16% market share.[14]                                          Indeed, participants can readily choose to submit their order flow to other exchange and off-exchange venues if they deem fee levels at those other venues to be more favorable.[15]                                          In addition to this the Exchange notes that at least one other exchange currently has MPID fees in place,[16]                                          which have been previously filed with the Commission. Moreover, 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.” The fact that this market is competitive has also long been recognized by the courts. In NetCoalition v. Securities and Exchange Commission, 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'. . . .”. Accordingly, the Exchange does not believe its proposed fee change imposes 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.

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

                    The foregoing rule change is effective upon filing pursuant to Section 19(b)(3)(A) of the Act [17]                                          and subparagraph (f)(2) of Rule 19b-4 thereunder,[18]                                          because it establishes a due, fee, or other charge imposed by the Exchange.                

                    At any time within 60 days of the filing of such 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 shall institute proceedings under Section 19(b)(2)(B) of the Act [19]                                          to determine whether the proposed rule change should be approved or disapproved.
