###### Securities and Exchange Commission

          - [Release No. 34-92217; File No. SR-BX-2021-027]

                    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 June 14, 2021, Nasdaq BX, Inc. (“BX” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “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

The Exchange proposes to extend the implementation date for changing the primary and secondary source of quotation data of MEMX LLC (“MEMX”) in the list of proprietary and network processor feeds that the Exchange utilizes for the handling, routing, and execution of orders as well as regulatory compliance processes related to those functions.

                    The text of the proposed rule change is available on the Exchange's website at                     *https://listingcenter.nasdaq.com/​rulebook/​bx/​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

BX is filing this proposal to extend the implementation date for changing the primary and secondary source of quotation data of MEMX in the list of proprietary and network processor feeds that the Exchange utilizes for the handling, routing, and execution of orders as well as regulatory compliance processes related to those functions.

                    BX proposed to amend Equity 4, Rule 4759 (Data Feeds Utilized) to change the primary and secondary source of quotation data of certain market centers in the list of proprietary and network processor feeds that the Exchange utilizes for the handling, routing, and execution of orders as well as regulatory compliance processes related to those functions.[3]                                          These changes were filed by BX on February 3, 2021 and published in the                     **Federal Register**                     on February 22, 2021.[4] 

BX initially proposed to implement the proposed rule change no later than ninety (90) days following the effective date of the proposed rule change. Due to the additional need for system configuration testing in advance of the date of launch, BX has decided to delay implementation for MEMX until the Q3 2021. The Exchange will announce the new implementation date in an Equity Trader Alert at least ten days in advance of implementing the changes.

#### 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]                                          in particular, in that it is designed to promote just and equitable principles of trade, 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.                

                    The purpose of this proposal is to inform the SEC and market participants of the new implementation date for changing the primary and secondary source of quotation data for MEMX. These enhancements were proposed in                           ( print page 33805)                        a rule filing that was submitted to the SEC, and this proposal does not make any substantive changes to that filing. BX is delaying the implementation date to allow for additional system configuration testing prior to implementation.                

### 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. As explained above, the purpose of this proposal is to inform the SEC and market participants of the new implementation date for changing the primary and secondary source of quotation data for MEMX, and the Exchange does not expect the date change to place any burden on competition.

### 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

                    Because the foregoing proposed rule change does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act [7]                                          and Rule 19b-4(f)(6) thereunder.[8] 

                    A proposed rule change filed under Rule 19b-4(f)(6) [9]                                          normally does not become operative prior to 30 days after the date of the filing. However, pursuant to Rule 19b-4(f)(6)(iii),[10]                                          the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay. Waiver of the operative delay would allow the Exchange to immediately extend the implementation date for changing the primary and secondary source of quotation data of MEMX to allow for additional system configuration testing prior to implementation. The Commission believes that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the operative delay and designates the proposed rule change operative upon filing.[11] 

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 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 to determine whether the proposed rule change should be approved or disapproved.

## IV. Solicitation of Comments
