###### Securities and Exchange Commission

          - [Release No. 34-99491; File No. SR-Phlx-2024-03]

                    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 January 29, 2024, Nasdaq PHLX LLC (“Phlx” or “Exchange”) filed with the Securities and Exchange Commission (“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 proposes to amend the Exchange's fees for Top of PHLX Options (TOPO), PHLX Orders, and TOPO Plus Orders.

                    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 purpose of the proposed rule change is to amend the Exchange's proprietary data fees for Top of PHLX Options (“TOPO”), PHLX Orders, and TOPO Plus Orders at Options 7, Section 10.[3] 

#### Top of PHLX Options (“TOPO”)

                    TOPO is a direct data feed that provides subscribers with PHLX Best Bid and Offer (“BBO”) [4]                                          and last sale information.[5]                                          The data distributed on TOPO is identical to the data simultaneously sent to the Options Price Reporting Authority (“OPRA”).[6]                                          The TOPO feed also provides administrative information to facilitate trading on the Exchange such as, for example, the list of symbols trading on a particular day.[7]                                          TOPO reduces the transmission and processing latencies for top of book information relative to the OPRA feed by avoiding the latencies generated by the latter in consolidating data.                

                    Monthly fees for TOPO are currently $2,000 for Internal Distributors,[8]                                          $2,500 for External Distributors,[9]                                          $1 for a Non-Professional Subscriber,[10]                                          and $40 for a Professional Subscriber.[11]                                          None of these fees have changed for over a decade, since January 2013.[12] 

#### PHLX Orders

                    PHLX Orders is a real-time order book feed with pricing information for displayed orders on the PHLX order book.[13]                                          The data provided for each options series includes the symbols (series and underlying security), a put or call indicator, expiration date, and the strike price of the series. It also provides the real-time status of simple and complex orders [14]                                          on the order book, including new orders and changes to orders resting on the PHLX book for all PHLX-listed options.[15]                                          The PHLX Orders feed includes data on the opening imbalance, Price Improvement XL (PIXL),[16]                                          and Complex Order Live Auction (COLA).[17]                                          A notification                           ( print page 10118)                        message is sent for symbols entering an auction.[18]                                          PHLX Orders also furnishes an historical record of all simple and complex order message data from the PHLX Orders data feed. PHLX Orders information is not sent to OPRA.[19] 

                    PHLX Orders is an alternative to PHLX Depth of Market. It is an optimized technical channel designed to lower technology costs, reduce processing time, and facilitate the ingestion of data while still providing customers insight beyond the top of book by viewing active buy and sell orders. PHLX Orders excludes quotations by market makers and other authorized entities that is included in PHLX Depth of Market.[20] 

What is the utility of an orders-only data feed? It provides customers with the opportunity to reduce bandwidth (and therefore data processing costs) by several orders of magnitude relative to the full depth of book feed, while retaining a view of customer orders (setting aside liquidity offered by market makers that is not attracting orders).

                    The December 2023 bandwidth report shows that the PHLX Depth of Market feed transmitted a maximum of 14.3 billion messages per day during the month of December,[21]                                          while the PHLX Orders feed transmitted a maximum of 53.6 million messages over the same period (41.5 million messages for simple orders, and 12.1 million messages for complex orders). The Exchange's full depth of book feed requires the customer to process over 200 times more messages than the orders feed over the course of a day; replacing a depth of book feed with an orders feed allows a customer to reduce the maximum number of daily messages it receives by 99.6%.                

To cite another example, the 1millisecond bandwidth peak for PHLX Depth of Market was 13.96 million messages; the comparable number of messages for orders was 1.45 million (891 thousand for simple and 561 thousand for complex orders). Replacing depth of book with orders can therefore reduce the number of messages processed at peak at the 1 millisecond bandwidth by nearly 90%.

Approximately 56% of customers who take any data feed at all from the PHLX exchange take an orders feed (either Orders only or TOPO Plus Orders) without depth of book. Another 38% of customers take both orders and depth feeds. The remaining 6% take either top of book or depth of book alone.

What type of customer takes an orders feed in lieu of depth? In general, firms that only need information on actively trading options do so. There are a great number of use cases that fit this broad description, but, for purposes of illustration, the Exchange is aware of at least two such types of customers.

The first is the market participant that does not engage in order routing. These are broker dealers that use third parties to route orders, either because the originating broker-dealer is not a member of the exchange or to save costs. Without the need for additional information to inform routing decisions, such customers often focus on active trading alone, and therefore purchase the orders feed.

A second category of customers are those that use options data to analyze trends in other markets. One example of this type of customer is the equity trader that analyzes equity-based options to gauge market sentiment in the underlying equity. For such customers, there is relatively little utility in the full depth feed, given that market sentiment is best gauged using options that are being actively traded, rather than those that are dormant.

As noted above, there are some customers that purchase both orders and depth. Vendors are one example of this type of customer. They purchase market data solely for resale, not for trading on behalf of themselves or others. Another example is the firm that uses orders for analysis and depth for order routing. As noted above, the orders feed can be useful for assessing sentiment in equity markets, while depth is often used in order routing decisions. Firms that engage in both functions can lower overall processing requirements by using orders for analytics and depth for routing.

Purchase of PHLX Orders is optional. Customers can obtain all of the data contained in PHLX Orders from PHLX Depth of Market feed, and may purchase the latter if they do not realize the cost savings offered by PHLX Orders.

PHLX Orders is a derivative product designed as a lower-cost alternative to a depth of book feed. It is not a complement to any other product offered by the Exchange or any of its competitors. Customers are free to purchase PHLX Orders or not, and can reject the feed for any reason, including the fee charged.

                    Current monthly fees for PHLX Orders are $3,000 for Internal Distributors, $3,500 for External Distributors, $1 for a Non-Professional Subscriber, and $40 for a Professional Subscriber. None of these fees have changes for over a decade, since January 2013.[22] 

#### TOPO Plus Orders

                    TOPO Plus is a direct market data product that offers subscribers both TOPO and PHLX Orders for a consolidated fee that is less than the combined fee of the two products.[23] 

Monthly fees for TOPO Plus Orders are currently $4,500 for Internal Distributors, $5,000 for External Distributors, $1 for a Non-Professional Subscriber, and $40 for a Professional Subscriber.

                    Internal Distributor fees for TOPO Plus Orders were modified in January 2018, over five years ago,[24]                                          but the other TOPO Plus Orders fees have not changed since January 2013.[25] 

#### Proposed Changes

For TOPO, the Exchange proposes to increase the monthly charge for Internal Distributors from $2,000 to $2,500, and the monthly charge for External Distributors from $2,500 to $3,000. No changes are proposed for Non-Professional and Professional Subscriber fees.

                    For PHLX Orders, the Exchange proposes to increase the monthly charge for Internal Distributors from $3,000 to $3,500, and the monthly charge for External Distributors from $3,500 to $4,000. No changes are proposed for Non-Professional and Professional Subscriber fees.                          ( print page 10119)    

For TOPO Plus Orders, the Exchange proposes to increase the monthly charge for Internal Distributors from $4,500 to $5,500, and the monthly charge for External Distributors from $5,000 to $6,000. No changes are proposed for Non-Professional and Professional Subscriber fees.

The proposed changes are designed to update data fees to reflect their current value, rather than their value when these fees were set 5 or 10 years ago.

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,[26]                                          in general, and furthers the objectives of Sections 6(b)(4) and 6(b)(5) of the Act,[27]                                          in particular, in that it provides for the equitable allocation of reasonable dues, fees and other charges among members and issuers and other persons using any facility, and is not designed to permit unfair discrimination between customers, issuers, brokers, or dealers.                

This belief is based on several factors.

*First,*                     exchange fees are constrained because market participants can choose among seventeen different venues for options trading, and therefore no single venue can charge excessive fees without losing customers and market share.                

*Second,*                     fees for TOPO are constrained because the identical top of book data is sent to OPRA, and certain market participants may choose to rely exclusively on OPRA rather than purchasing the proprietary data product.                

*Third,*                     the purchase of PHLX Orders is optional. It is designed as a lower-cost alternative to depth of book, and, as such, is not a complement to any other product offered by the Exchange or any of its competitors. Customers may purchase PHLX Orders or not, and can reject the feed for any reason, including the fee charged.                

*Fourth,*                     the proposed fees are comparable to, and in some cases less than, those of similarly situated exchanges.                

*Fifth,*                     the current fees do not properly reflect the value of the underlying product, as fees for the products in question have been static in nominal terms, and therefore falling in real terms (due to inflation), while the amount of information transmitted in those fees have more than doubled in just the past five years, reflecting a substantial increase in customer value due to the significantly higher levels of liquidity currently available on the Exchange.                

*Sixth,*                     higher fees for the external distribution of TOPO, PHLX Orders, and TOPO Plus Orders are based on the additional value vendors receive from distributing data to their own customers and typically charging for the service.                

#### Customers Have A Choice in Trading Venue

                    Customers face many choices in where to trade options. Until recently, sixteen exchanges have offered options trading services,[28]                                          and they are now being joined by a 17th member.[29]                                          Not a single options exchange trades more than 11 percent of the options market by volume.[30]                                          PHLX, the second largest options exchange by volume, only has 9 percent of the options market.[31]                                          Only one of the 17 options exchanges have a market share over 10 percent.[32]                                          This broad dispersion of market share demonstrates that market participants can and do exercise choice in options trading venues. As the number of exchanges continues to grow, competition will become fiercer and customer choice will continue to expand.                

                    In light of the number of trading venues available to customers, the Exchange must price its products, including TOPO, PHLX Orders, and TOPO Plus Orders (as well as other products), competitively. If not, customers would move to other venues. “If competitive forces are operative, the self-interest of the exchanges themselves will work powerfully to constrain unreasonable or unfair behavior.” [33]                                          Accordingly, “the existence of significant competition provides a substantial basis for finding that the terms of an exchange's fee proposal are equitable, fair, reasonable, and not unreasonably or unfairly discriminatory.” [34] 

#### The Top of Book Data in TOPO Is Sent to OPRA

                    The top of book data in TOPO is sent to OPRA; under OPRA rules, proprietary options information is available to customers that have equivalent access to OPRA information, and therefore is supplementary to the OPRA feed.[35]                                          Specifically, Section 5.2(c)(iii) of the OPRA Plan provides that “[a] Member [of the OPRA Plan] may disseminate its Proprietary Information,” provided that “such dissemination is limited to other Members and to persons who also have equivalent access to consolidated Options Information disseminated by OPRA for the same classes or series of options that are included in the Proprietary Information. . . .” [36]                                          “Consolidated Options Information” refers to “consolidated Last Sale Reports combined with either consolidated Quotation Information or the BBO furnished by OPRA.” [37]                                          Access is deemed to be “equivalent” “if both if both kinds of information are equally accessible on the same terminal or work station . . . .” [38] 

                    Any customer that purchases proprietary options data from the Exchange, including TOPO and TOPO Plus Orders, must also have equivalent access to the OPRA Plan. As noted above, the best bid and offer and last sale information available from TOPO and TOPO Plus Orders fees is identical to the information simultaneously sent to OPRA by the Exchange.[39]                                          OPRA provides NBBO and last sale information on options transactions. TOPO and TOPO Plus Orders provide additional administrative information unique to trading on the Exchange, and also reduce the transmission and processing latencies generated through the process of consolidating data into                           ( print page 10120)                        the OPRA feed.[40]                                          Because top of book and last sale information is available on OPRA as well as TOPO, and customers who purchase TOPO have equivalent access to the OPRA feed, certain customers may choose to rely on the OPRA feed in lieu of purchasing PHLX data, thereby limiting the ability of the Exchange from charging excessive fees for its TOPO and TOPO Plus Orders feeds.                

#### The Purchase of PHLX Orders Is Optional

Purchase of PHLX Orders is optional. As explained above, customers can obtain all of the data contained in PHLX Orders from PHLX Depth of Market feed, and may purchase the latter if they do not realize the cost savings offered by PHLX Orders. PHLX Orders is not a complement to any other product offered by the Exchange or any of its competitors; customers are free to purchase PHLX Orders or not, and can reject the feed for any reason, including the fee charged.

#### The Proposed Fees are Comparable to Those of Other Exchanges

                    The proposed fees are comparable to, and in some cases less than, those of other similarly situated exchange fees. Options market statistics show that PHLX has a market share of approximately 9%. ARCA, with an 11% market share, and CBOE, with a 9% market share, are its closest competitors.[41] 

                    To obtain top of book and depth of book information for internal distribution (including both simple and complex options) from ARCA, a customer would be required to pay an Access Fee of $3,000 per month, a Non-Display fee of at least $5,000 per month for simple options, and a Non-Display fee of $1,000 for Complex Options, for a total of $9,000 per month.[42]                                          To obtain the same information from PHLX under the new proposal, a customer would pay the Internal Distributor fee of $2,500 for TOPO, and an Internal Distributor fee of $4,000 for PHLX Depth Data,[43]                                          for a total of $6,500 per month.                

                    To obtain comparable information for Cboe Options, a customer would be required to pay a combined fee of $9,000 per month.[44]                                          As noted above, a PHLX customer would pay the Internal Distributor fee of $2,500 for TOPO, and an Internal Distributor fee of $4,000 for PHLX Depth Data,[45]                                          for a total of $6,500 per month.                

As such, the proposed fees are comparable to fees charged by industry peers, and therefore presumptively reasonable.

#### Real Exchange Fees Have Fallen While Traffic Has Increased

                    As explained above, the Internal Distributor fee for TOPO Plus Orders was increased in 2018,[46]                                          while none of the other fees have changed for over a decade, since January 2013.[47]                                          This means that fees for TOPO, PHLX Orders, and TOPO Plus Orders have fallen in real terms due to inflation. Using data generated by the Department of Commerce to estimate inflation in the market for portfolio management and investment services,[48]                                          inflation has increased prices by 63.9% since January 2013, when most of the fees at issue were set, and 15.7% since January 2018, when internal distributor fees for TOPO Plus Orders were last modified. At the same time, the average daily message count of PHLX has more than doubled in just five years, from approximately 3.0 billion messages per day in 2018 to approximately 8.2 billion messages in 2023.[49]                                          PHLX grew in conjunction with options trading overall, which in the aggregate grew at a faster pace than PHLX alone. Between January 2018 and December 2023, options volume on PHLX grew by 31%, while options volume on all exchanges nearly doubled, from 467 million options to 912 million instruments.[50] 

Growth in options trading means better value for the consumer. The greater variety of options contracts traded means that customers have more choice. The greater number of buyers and sellers in the market means that there is more liquidity, resulting in tighter spreads and better consumer value on each trade. Greater choice and tighter spreads mean that the consumer obtains more value from options markets overall, which should be reflected in fees for exchange services, including market data. The proposal is therefore reasonable in light of the substantial increase in customer value generate by the higher levels of liquidity now available on the Exchange, coupled with the fall in real prices due to inflation.

#### External Distributors Receive Additional Value

External Distributors receive additional value not available to Internal Distributors by disseminating information externally and typically charging for the service. This additional value supports higher fees for external distribution for TOPO, PHLX Orders, and TOPO Plus Orders. Higher fees for external distribution of data are common throughout the industry, and nearly universal among exchanges. The difference in value between internal and external distribution is also reflected in the current fee schedule, which has previously been shown to be consistent with the Exchange Act.

* * * * *

                    In summary, the proposal represents an equitable allocation of reasonable dues, fees and other charges because: (i) customers have a choice in trading venue, and will exercise that choice and trade at another venue if exchange fees are not set competitively; (ii) the top of book data sent in the TOPO feed are also sent to OPRA, and customers have the option of relying on OPRA data; (iii) the purchase of PHLX Orders is entirely optional as it is a low-cost alternative to the PHLX Depth of Market product; (iv) the proposed fees are comparable to those of other exchanges; (v) exchange                           ( print page 10121)                        fees have fallen in real terms while the amount of liquidity available on the exchange has increased, and (vi) external vendors receive additional value from distributing data to their own customers and typically charging for the service, and therefore charging higher fees for external distribution is fair and reasonable.                

#### No Unfair Discrimination

The Proposal is not unfairly discriminatory. The three market data feeds at issue here—TOPO, PHLX Orders, and TOPO Plus Orders—are used by a variety of market participants for a variety of purposes. Users include regulators, market makers, competing exchanges, media, retail, academics, portfolio managers. Market data feeds will be available to members of all of these groups on a non-discriminatory basis.

### 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 not necessary or appropriate in furtherance of the purposes of the Act.

Nothing in the Proposal burdens inter-market competition (the competition among self-regulatory organizations) because approval of the Proposal does not impose any burden on the ability of other options exchanges to compete. PHLX fees are comparable to, and in some cases less than, those of other exchanges, as discussed above.

Nothing in the Proposal burdens intra-market competition (the competition among consumers of exchange data) because PHLX market data is available to any customer under the same fee schedule as any other customer, and any market participant that wishes to purchase PHLX market data can do so on a non-discriminatory basis.

### C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

No written comments were either solicited or received.

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

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: (i) necessary or appropriate in the public interest; (ii) for the protection of investors; or (iii) otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
