          - [Release No. 34-101488; File No. SR-Phlx-2024-54]

      ( print page 88092)    
                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on October 18, 2024, Nasdaq PHLX LLC (“Phlx” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “Commission”) a 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 proposes to amend Options 3, Section 13, Price Improvement XL (“PIXL”).

                    The text of the proposed rule change is available on the Exchange's website at                     *https://listingcenter.nasdaq.com/​rulebook/​phlx/​rules,*                     at the principal office of the Exchange, 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 Options 3, Section 13, Price Improvement XL (“PIXL”) to permit orders for the accounts of appointed Market Makers to be solicited for PIXL Auctions for XND options only. XND options are options based on 1/100 the value of the Nasdaq-100 (“XND” or “XND options”). Today, Cboe Exchange, Inc. (“Cboe”) permits orders for the accounts of Market-Makers with an appointment in SPX to be solicited for the Initiating Order submitted for execution against an Agency Order in SPX options into an AIM Auction pursuant to Rule 5.37.[3] 

                    The Exchange proposes to amend Options 3, Section 13(a)(8) to permit orders for the accounts of Market Makers with an appointment in XND to be solicited for the Initiating Order [4]                                          submitted for execution against a PIXL Order in XND options into a PIXL Auction pursuant to Options 3, Section 13. Today, Options 3, Section 13(a)(8) provides that, “[a]n Initiating Order may not be a solicited order for the account of any Exchange Lead Market Maker, SQT, RSQT or non-streaming Market Maker assigned in the affected series.” No similar restriction applies to crossing transactions in open outcry trading, where XND options also trade. As further discussed below, brokers seeking liquidity to execute against Public Customer orders on the trading floor regularly solicit appointed XND Market Makers for this liquidity, as they are generally the primary source of pricing and liquidity for those options.                

The Exchange believes not permitting Market Makers appointed in XND to participate as contras in the PIXL Auction in XND makes it difficult for brokers to find sufficient liquidity to fill their customer orders. For example, if a Public Customer order is not fully executable against electronic bids and offers, a floor broker can attempt to execute the order, or remainder thereof, on the trading floor, where the liquidity to trade with this remainder is generally provided by Market Makers in the open outcry trading crowd. Additionally, brokers may solicit liquidity from upstairs Market Maker firms.

The Exchange believes brokers will have difficulty finding sufficient liquidity to initiate PIXL Auctions from only market participants that are not Market-Makers appointed in XND, thereby denying smaller, retail-sized XND options price improvement benefits. The Exchange believes it is appropriate to permit orders for the account of appointed XND Market Makers, similar to Cboe's SPX, to be submitted as the contra order, as the Exchange believes the liquidity provided by XND Market Makers will need to be available for brokers to initiate PIXL Auctions in XND and create potential price improvement opportunities for those retail-sized orders. If XND Market Makers cannot be solicited for XND PIXL Auctions, the Exchange believes brokers may not be able to initiate as many XND PIXL Auctions for their retail orders, which may reduce the price improvement opportunities available for those orders. The Exchange notes that today, there are three electronic Market Maker firms with XND appointments.

In multi-list classes, many Market Makers serve as both appointed Market Makers on the Exchange and as away market makers that are registered on other options exchanges. These firms, as a result, can use their accounts for their away market maker activities for being solicited with respect to PIXL Auctions. In general, solicited orders submitted as the Initiating Order for PIXL Auctions are almost always comprised of orders for the accounts of away market makers. However, XND is an exclusively listed class on the Exchange, so a firm cannot serve as an XND away market maker. Permitting orders for the account of an appointed XND Market Makers, similar to Cboe's SPX, to be submitted as the contra order will allow brokers to more efficiently locate liquidity to initiate PIXL Auctions to fill their Public Customer orders, particularly during times of volatility, which may create additional execution and price improvement opportunities for Public Customers at all times. The Exchange believes the proposed rule change will, therefore, provide retail-sized orders with similar price improvement opportunities with PIXL as is the case with the trading floor. Permitting XND Market Makers to serve as contra parties to crossing transactions submitted into a PIXL Auction will also further align PIXL Auctions with XND crossing executions that occur on the trading floor. XND Market Makers frequently serve as contra parties to crossing transactions on the trading floor.

#### Implementation

                    The Exchange proposes to implement this rule change on or before Q2 of 2025.                          ( print page 88093)    

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,[5]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act.[6]                                          Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) [7]                                          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.                

In particular, the Exchange believes the proposed rule change will benefit investors. The proposed rule change will permit the primary XND liquidity providers on the Exchange to provide the liquidity necessary for brokers to initiate XND PIXL Auctions for their Public Customer orders. If brokers can solicit the primary liquidity providers in XND for PIXL Auctions the Exchange believes brokers will be able to more efficiently locate liquidity to fill their Public Customer orders, particularly during times of volatility. The Exchange believes the proposed rule change will, therefore, provide retail-sized orders with similar price improvement opportunities as on the trading floor. As a result, the Exchange believes the proposed rule change will permit sufficient liquidity to be available for PIXL Auctions, which may create additional execution and price improvement opportunities for Public Customers, including retail customers.

The Exchange also believes the proposed rule change will promote just and equitable principles of trade and remove impediments to and perfect the mechanism of a free and open market and a national market system because it will align the XND PIXL Auction process with the open outcry crossing process, and thus align the execution and price improvement opportunities available in both auctions by permitting the same participants to be solicited as contras in both types of auctions in XND. Currently, XND Market Makers may be solicited with respect to crossing transactions on the trading floor. However, pursuant to Options 3, Section 13 governing PIXL, XND Market Makers would not be able to be solicited to initiate PIXL Auctions. The Exchange believes there is no reason to restrict XND Market Makers' ability to provide liquidity into XND PIXL Auctions when they are able to similarly provide, and do provide, that liquidity for open outcry XND crossing transactions. Today, Cboe permits orders for the accounts of Market-Makers with an appointment in SPX to be solicited for the Initiating Order submitted for execution against an Agency Order in SPX options into an AIM Auction pursuant to Cboe Rule 5.37.

The Exchange believes the proposed rule change will promote competition in XND PIXL Auctions, including competition to initiate XND PIXL Auctions, which will remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors. As noted above, there are three electronic Market Maker firms with XND appointments. The Exchange believes the availability of this liquidity available to PIXL Orders will positively affect the experience for PIXL Orders and overall quality of the auctions. Furthermore, the Exchange believes increasing the number of market participants available to be solicited may increase competition to provide Initiating Orders, which may lead to a PIXL Auction being initiated at a better price. More market participants competing to provide Initiating Orders may lead to solicited parties providing more aggressive initial prices. The Exchange believes the ability of all market participants, including appointed Market Makers that did not submit an Initiating Order, to submit responses to a PIXL Auction will continue to provide competition for executions against Agency Orders. The Exchange does not believe the proposed rule change will adversely impact the quoting behavior of XND Market Makers.

The Exchange believes any risk that appointed Market Makers may misuse the nonpublic information of an upcoming XND PIXL Auction is de minimis. Currently, that same risk is present for non-appointed Market Makers, but the Exchange has not observed any trends of solicited market participants separately submitting unrelated orders as a result of knowledge of impending PIXL Auctions in other classes. Phlx Options 3, Section 13(d) prohibits a pattern or practice of submitting multiple orders in response to a PAN at a particular price point that exceeds, in the aggregate, the size of the PIXL Order, will be deemed conduct inconsistent with just and equitable principles of trade and a violation of General 9, Section 1(c). Further, Phlx General 9, Section 21 requires members to establish, maintain, and enforce written policies and procedures reasonably designed to prevent the misuse of material, nonpublic information by members and their associated persons.

Finally, the Exchange believes the proposed rule change is not designed to permit unfair discrimination between customers, issuers, brokers, or dealers because it will permit orders for accounts of appointed XND Market Makers to be solicited in the same manner as orders for the accounts of all other market participants in XND PIXL Auctions. Currently, all market participants other than appointed XND Market Makers would be able to be solicited as the contra and submit responses in PIXL Auctions, while appointed XND Market Makers would be restricted to only submitting responses. The Exchange believes that this proposal may increase execution and price improvement opportunities for Public Customers' XND orders, where the ability for away market makers to provide liquidity is limited.

### 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 Exchange does not believe the proposed rule change will impose any burden on intra-market competition that is not necessary or appropriate in furtherance of the purposes of the Act because it will provide XND Market Makers with the same execution opportunities in PIXL Auctions that would be available to all other market participants. Additionally, the proposed rule change will align open outcry and electronic crossing auctions for XND and the execution and price improvement opportunities available in both auctions by permitting the same participants to be solicited as contras in both types of auctions across XND. As a result, the Exchange believes it is appropriate for the electronic crossing mechanism to more closely replicate the open outcry crossing process in XND in order to minimize any impact on the market for those options. Unlike in multi-list classes, Market Maker firms cannot serve as XND market makers at other options exchanges. The Exchange further believes the restriction of this change to XND will preserve certain aspects of market structure that are important to maintain Market Maker                           ( print page 88094)                        incentives to provide electronic liquidity in XND options.                

The Exchange does not believe the proposed rule change will impose any burden on intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act because it relates to orders in an exclusively listed class submitted into a PIXL Auction on the Exchange. Additionally, the Exchange notes that Cboe permits orders for the accounts of Market-Makers with an appointment in SPX to be solicited for the Initiating Order submitted for execution against an Agency Order in SPX options into an AIM Auction pursuant to Cboe Rule 5.37. The Exchange believes the proposed rule change may improve price competition for smaller-sized orders within PIXL Auctions for XND options, because the primary liquidity providers will be available for the solicitation necessary to initiate those auctions.
