CME's Perp Lawsuit Has Kalshi, Coinbase & Kraken All Sweating The Same Swaps 🌡️

CME Group will file a federal lawsuit against the U.S. Commodity Futures Trading Commission on Thursday, June 18, over the agency's late-May approval that cleared prediction-market platform Kalshi to list a Bitcoin perpetual futures contract, outgoing CEO Terrence Duffy told CNBC's "Fast Money" on Wednesday. CME later confirmed the filing plan to Reuters. The suit marks the first direct legal challenge by the world's largest futures exchange operator against a regulator weighing in on U.S.-listed perpetual futures, instruments that never expire and rely on periodic funding payments between traders rather than monthly roll dates.

Duffy's core argument is one of classification. He contends that perpetual futures are swaps under the Dodd-Frank Act, not futures, because they involve two parties exchanging funding-rate payments without a defined expiration or delivery date. "Under the Dodd-Frank Act, it clearly defines what a swap is and what a future is, and when there's two parties exchanging payments to each other, that's deemed a swap," Duffy told CNBC. CFTC Chair Michael Selig defended the approval earlier the same week, telling CNBC it was "time to approve regulated futures contracts that have no expiration date," while a CFTC spokesperson called the threatened suit "frivolous" and said the agency looks forward to dismissing it.

CME also points to its exclusive licensing agreements with benchmark providers as leverage. "We have an exclusive license with every single provider of the benchmarks. So all of these would have to go through CME regardless of the perpetual," Duffy said. If a court reclassifies perpetual futures as swaps, rival offerings from Kalshi, Coinbase, and Kraken would need to route through CME's framework regardless of how their products are labeled, a structural outcome Duffy described as inevitable. The CFTC has separately cleared crypto exchange Coinbase to connect U.S. customers to offshore perps and issued a December order under former chair Caroline Pham allowing Bitnomial to offer similar products, though those carry a 25-year limit and are not truly perpetual.

The legal community is split. Robert Schwertz, a former CFTC lawyer, said the Kalshi order "does not say anything about swaps, and the CFTC has said before that perps are swaps. That could be a pretty big miss from an APA standpoint." Amanda Fischer, a Biden-era SEC Chief of Staff, called the CME move "huge news" and said it "signals that the bonanza of giveaways to crypto and prediction markets won't go unchallenged." Duffy, who previously likened current market conditions to the run-up to the 2008 crash and warned that "the housing market has been supplanted by the speculation market," said he has spent the past eight months preparing the challenge with CME's board. "I'm always up for a good battle," he said. "I've never shied away from one, and I won't shy away from this."

The timing carries additional weight. The lawsuit arrives as legislators debate the scope of CFTC jurisdiction over digital commodity derivatives through measures including the CLARITY Act, which is moving through the Senate and would formalize the agency's authority over that market segment, and follows the CFTC signaling plans to block CME's rollout of 24/7 trading for gold and oil futures, a decision the regulator said could "worsen" oil price volatility. The exchange announced the same day that Duffy will step down in March 2027, with a successor named, and that legal fight landing at the start of a leadership transition.
