RE: Modifications to the E-Mini Trade at Cash Open ("TACO") Futures Market Maker 

Program

CME Submission No. 23-542

Dear Mr. Kirkpatrick:

Chicago Mercantile Exchange Inc. (“CME” or “Exchange”) hereby notifies the Commodity Futures Trading 

Commission (“CFTC” or “Commission”) of plans to modify the E-mini TACO Futures Market Maker Program 

(“Program”). The modifications to the Program will become effective on February 1, 2024.

Exhibit 1 sets forth the terms of this Program. Modifications appear below, with additions underlined and deletions 

overstruck. 

The Exchange reviewed the designated contract market core principles (“Core Principles”) as set forth in the 

Commodity Exchange Act (“CEA” or “Act”). During the review, CME staff identified the following Core Principles as 

potentially being impacted: Monitoring of Trading, Execution of Transactions, Protection of Market Participants, 

Compliance with Rules, Availability of General Information, and Recordkeeping. 

The Program does not impact the Exchange’s ability to perform its trade practice and market surveillance obligations 

under the CEA and the Exchange’s market regulation staff will monitor trading in the Program’s products to prevent 

manipulative trading and market abuse. Additionally, the Exchange has implemented systems to track Program 

participants’ obligations to ensure proper distribution of earned incentives. The incentives in the Program do not 

impact the Exchange’s order execution. Participants in the Program will be selected by Exchange staff using criteria 

as further stated in Exhibit 1. Chapter 4 of the CME rules includes prohibitions against fraudulent, non-competitive, 

unfair or abusive practices. All participants must execute a contractual agreement with the Exchange in which each 

participant will expressly agree to comply with and be subject to applicable regulations and CME rules. The Program 

is subject to the Exchange’s record retention policies which comply with the CEA. 

CME certifies that the Program complies with the CEA and the regulations thereunder. There were no substantive 

opposing views to this Program.

The Exchange certifies that this submission has been concurrently posted on the Exchange’s website at 

http://www.cmegroup.com/market-regulation/rule-filings.html.

If you require any additional information regarding this submission, please e-mail 

CMEGSubmissionInquiry@cmegroup.com or contact Rachel Johnson at 312-466-4393 or via e-mail at 

Rachel.Johnson@cmegroup.com. Please reference our CME Submission No. 23-542 in any related correspondence.

Sincerely,

/s/ Timothy Elliott

Managing Director and Chief Regulatory Counsel

Attachment: Exhibit 1
EXHIBIT 1

E-mini TACO Futures Market Maker Program

Program Purpose

The purpose of this Program is to support development in the products listed below. The resulting 

increase in liquidity on the central limit order book benefits all participant segments in the market.

Product Scope

TACO on E-mini S&P 500 Futures (“ESQ”), E-mini Nasdaq-100 Futures (“NQQ”), and E-mini Russell

2000 Futures (“RTQ”) that are traded on the CME Globex Platform (“Products”). 

Eligible Participants

CME may designate up to seven (7) participants in the Program. Participants may be CME members or 

non-members. Potential participants are required to submit an application/bid sheet to the Exchange as 

part of a competitive application process which is used to determine eligibility. In determining whether or 

not a prospective participant is selected to participate in the Program, Exchange staff may take into 

account a variety of factors including the strength of the quoting obligations the prospective participant is 

willing to commit to provide, whether Exchange staff believes that the prospective participant can 

maintain such obligations, and historical volume trading similar products. The Exchange may, from time to 

time, add or subtract from the aforementioned requirements as it deems necessary.

Program Term

Start date is July 16, 2018. End date is January 31, 2024 January 31, 2025.

Obligations

In order to be eligible to receive the incentives, participants must quote two-sided markets in the 

applicable Products, at predetermined average bid/ask spreads and minimum quote sizes.

Incentives

Upon meeting the obligations, as determined by the Exchange, participants may be eligible to receive 

predetermined incentives.

Monitoring and Termination of Status

The Exchange shall monitor trading activity and participants’ performance and shall retain the right to 

revoke participant status if it concludes from review that a participant no longer meets the eligibility 

requirements or fails to meet the obligations of the Program.
