CME sues CFTC over Bitcoin perpetual futures classification

CME Group has sued the Commodity Futures Trading Commission, asking a court to treat Bitcoin perpetual futures, specifically contracts listed by rival exchange KalshiEX, as swaps rather than futures, reportedly filing the case on June 18, less than three weeks after the CFTC accepted KalshiEX’s Bitcoin perpetual contract as a futures product on May 29.

The distinction carries weight. Under the Dodd-Frank framework, swaps face stricter registration, reporting and business conduct rules, while futures often face lighter-touch oversight. If perpetuals were reclassified as swaps, platforms would have to register as swap dealers and meet higher capital and compliance requirements. That would raise costs across the domestic perpetual market, which in turn would likely slow its rollout in the United States.

The money at stake is large. Centralized perpetual exchanges reportedly handled roughly $86.2 trillion in notional volume for 2025, up 47.4% year over year, and decentralized platforms added another $6.7 trillion. Bank of America has projected crypto perpetual trading volume would exceed $93 trillion in notional value for 2025. Against that, CME Group’s own crypto futures averaged 278,000 contracts per day in 2025, about $12 billion in daily notional value, a scale that works out to roughly $4.4 trillion annualized, or under 5% of the perpetual market by one tally in the coverage.

That gap explains the lawsuit’s shape. Offshore platforms such as Binance, Bybit and OKX built large perpetual trading businesses outside US regulatory reach over years, and CME Group is trying to shape the domestic market through the classification question rather than by matching rivals’ product pace. KalshiEX, which began as a prediction markets platform, has been expanding into new product categories, and its May 29 approval put a US-regulated Bitcoin perpetual in front of the incumbents.

CME Group’s crypto business is not standing still while it litigates. The exchange expanded its derivatives suite to Cardano, Chainlink and Stellar earlier this year, and it has confirmed plans for a proprietary collateral coin piloted from its Q4 earnings call.
