A regulatory fight is unfolding between two of the largest names in U.S. derivatives over how onchain perpetual futures should be classified — and who gets to approve them. CME Group, the world's largest futures exchange operator, has sued the Commodity Futures Trading Commission and its chair, Mike Selig, after the agency approved the first regulated crypto perpetual futures products in the U.S., listed on Kalshi and Coinbase.
Kalshi's perpetual product found demand almost immediately, crossing $1 billion in trading volume within its first week on the market — a pace that underscored what's at stake for incumbent exchanges like CME as trading activity shifts toward always-on, expiration-free contracts.
CME's Core Legal Argument
CME Group Chairman Terry Duffy is leading the opposition, and the company's suit rests on a specific classification dispute: CME contends perpetual futures are legally "swaps," not "futures," because they lack the expiration dates that define a futures contract. That distinction matters because swaps and futures fall under different regulatory regimes with different obligations. "When two parties exchange payments to each other, that is deemed a swap," Duffy said. "When you're dealing in swaps contracts, that comes with obligations to maintain five-day margin."
CME's complaint also takes aim at process — the suit alleges the CFTC rubber-stamped Kalshi's application just one day after it was submitted, and that the agency has been leaning on case-by-case policy statements rather than formal rulemaking, a route that sidesteps the public comment periods typically required for major regulatory shifts. Notably, Chair Selig has been operating as the CFTC's sole sitting commissioner, adding to CME's argument that the approvals lacked adequate scrutiny.

What's Actually at Stake
Beyond the legal technicalities, CME argues perpetual futures don't serve the same institutional hedging purpose that traditional futures do, and that enforcement gaps could let non-U.S. traders access U.S.-based platforms without proper oversight. The company points to global scale as evidence of how large this market has already become: non-U.S. perpetual futures volume reportedly reached $60 trillion last year, much of it flowing through decentralized exchanges like Hyperliquid, which offer 24/7 trading on assets ranging from crypto to onchain oil price contracts — a category that saw a spike in interest during the recent Iran conflict.
CME has already notched one concrete win in its broader campaign: after filing suit, the company succeeded in blocking a CFTC-approved plan for 24/7 WTI crude oil futures trading, a sign the litigation strategy is already shaping the regulatory landscape beyond the crypto perpetuals dispute itself.
A Contested Legal Outcome
Financial policy analyst Jaret Seiberg of TD Cowen said CME may hold the legal upper hand given how differently swaps and futures are regulated. Jake Chervinsky, CEO of the Hyperliquid Policy Center, and Liz Davis, a partner at Davis Wright Tremaine, are among the industry and legal voices tracking the case as a potential precedent for how far the CFTC can stretch its existing rulebook to accommodate crypto-native products without new legislation or formal rulemaking.
The outcome will likely determine whether perpetual futures — a product format that has already become dominant in offshore and decentralized crypto trading — can scale within U.S. regulatory boundaries under the CFTC's current approach, or whether exchanges like Kalshi and Coinbase will need Congress or a formal rulemaking process to secure firmer legal ground.
