CME Group plans to sue the CFTC over its approval of Bitcoin perpetual futures products in the United States. The company’s outgoing chief executive, Terry Duffy, confirmed the legal challenge during a CNBC interview. CME said it will file the lawsuit on Thursday and disputes how regulators classified the products.
Terry Duffy said CME Group disagrees with the CFTC’s decision to treat perpetual futures as futures contracts. He argued that the products meet the legal definition of swaps under the Dodd-Frank Act. Therefore, he said they should follow a different regulatory framework.

Duffy explained that swaps involve payment exchanges between counterparties over time. He told CNBC that federal law clearly distinguishes swaps from futures contracts. As a result, CME believes regulators applied the wrong classification.
He also questioned the speed of the approval process. Duffy said the CFTC cleared a new product faster than many standard reviews. Consequently, CME decided to challenge the decision in court.
The CME chief said the company spent eight months preparing the case. He stated that CME worked closely with its board during that period. He also welcomed the legal dispute and said, “I’m always up for a good battle.”
Perpetual futures differ from traditional futures because they do not expire. Instead, traders exchange periodic funding payments to maintain price alignment. These products can also offer leverage of up to 50-to-1.
The dispute follows recent approvals involving crypto perpetual futures products. In late May, the CFTC approved prediction market operator Kalshi to list a Bitcoin perpetual futures contract. The regulator also cleared Coinbase to connect U.S. users to offshore perpetual futures markets.
Those decisions opened access to products that previously operated mainly on offshore venues. As a result, U.S. traders gained access through regulated domestic platforms. The approvals marked a new step for crypto derivatives trading in the country.
CFTC Chair Michael Selig defended the agency’s position. He said the approvals help bring one of crypto’s most active markets into the United States. The agency has maintained that regulated access offers a suitable framework for these products.
A CFTC spokesperson responded to CME’s planned lawsuit. The spokesperson told Reuters that the agency looks forward to addressing the claims. The spokesperson also described the case as a “frivolous” lawsuit.
Duffy has criticized the growth of speculative trading products in recent weeks. Earlier this month, he compared current conditions to those before the 2008 financial crisis. He argued that speculative markets could create broader risks if activity continues to expand.
The legal challenge emerged on the same day CME announced a leadership change. The company named President and Chief Financial Officer Lynne Fitzpatrick as Duffy’s successor. She will become the first woman to lead CME as chief executive.
Duffy will remain in his role until March 2027. After that transition, Fitzpatrick will assume responsibility for the exchange operator. CME confirmed the succession plan while preparing its court filing against the CFTC.
