Overview
Jonathan L. Marcus, Senior Managing Director and General Counsel at CME Group, disposed of 3,291 shares of Class A common stock on March 17, 2026, at a price of $333.37 per share, resulting in proceeds of approximately $1.1 million, according to a Form 4 filed with the Securities and Exchange Commission. The filing states the sale was executed under a Rule 10b5-1 trading plan that Marcus adopted on February 18, 2025.
Following the transaction, Marcus directly holds 7,192 shares of CME Group common stock. At the time the sale was reported, CME shares were trading at $311.82, reflecting gains of nearly 16% year-to-date and roughly 21% over the prior six months. An analysis from InvestingPro, cited in the filing notes, suggests the stock is trading above its Fair Value.
Dividend and research notes
An InvestingPro tip included with the disclosure highlights that CME Group has paid dividends for 24 consecutive years and currently yields 1.68%. The note also indicates that a detailed Pro Research Report on CME is available through InvestingPro alongside reports for more than 1,400 other U.S. equities.
Operational and market developments at CME
Separately from the insider sale, CME Group reported a new record in open interest for its U.S. Treasury futures and options markets, reaching 36.3 million contracts and surpassing the prior record set in November 2025. The company announced intentions to extend trading hours for its cryptocurrency futures and options to a 24/7 schedule beginning May 29, contingent on receiving regulatory approval.
CME cited record cryptocurrency trading activity in 2025, with $3 trillion in notional volume for the year. The exchange also experienced a technical issue that temporarily halted trading in its metals and natural gas futures and options markets; trading was scheduled to resume according to announced pre-open and open times for those contracts.
In another operational move, CME is reportedly preparing to approve aluminum warehouses in Taiwan and Hong Kong, a step described as an expansion of its storage network across Asia. The company presented these developments as part of continued efforts to broaden trading and storage capabilities across multiple markets.
Context and limits of information
The SEC Form 4 filing provides the specific details of Marcus's sale and post-transaction holdings and confirms the use of a Rule 10b5-1 plan. Beyond the items disclosed, the filing and related notes do not provide additional commentary from company management about the insider transaction or the strategic rationale for the warehouse approvals or trading-hour changes. The planned extension of crypto trading hours is conditional on regulatory clearance.
