CME Sues CFTC Over Kalshi Bitcoin Perpetual Classification

The futures exchange giant is challenging the regulator’s approval of Kalshi’s BTCPERP contract, arguing it should be classified as a swap under stricter Dodd-Frank rules rather than as a futures product.

CME Group announced mid-June that it will sue the CFTC, contending that Kalshi’s Bitcoin perpetual contract was wrongly approved as a futures product. The complaint centers on regulatory classification: CME argues the contract should instead be regulated as a swap under the Dodd-Frank Act, subjecting it to more stringent clearing and capital requirements.

The CFTC approved KalshiEX’s BTCPERP contract on May 29, just one day after Kalshi submitted it under Regulation 40.3. The contract allows leverage as high as 50-to-1 with automatic liquidation during sharp price moves and carries no expiry date, referencing spot Bitcoin directly. Since launch, the contract has generated approximately $5 billion in volume.

The lawsuit reflects deeper tensions over how the CFTC is reshaping the derivatives landscape. Shares of CME, Cboe Global Markets, and ICE fell following the CFTC’s approval, with investors viewing the move as a long-term competitive threat to incumbent exchanges. The Futures Industry Association and its Principal Traders Group told the CFTC that perpetual derivatives raise trading and clearing risk questions and urged clearer definitions before approving additional products.

Broader Regulatory Friction

Kalshi’s BTCPERP launch is part of a wider push to bring regulated crypto derivatives onshore. Coinbase has also brought regulated crypto perpetual contracts to US investors through a domestic regulated exchange. Meanwhile, Polymarket advertises prediction market perps with early-access invitations, and Hyperliquid has added outcome markets for off-chain events including US inflation data and Federal Reserve decisions.

The CFTC’s regulatory approach is colliding with state authorities. On June 12, the CFTC sued New Mexico to block state gaming enforcement against CFTC-registered contract markets, citing similar conflicts in Arizona, Connecticut, Illinois, New York, Minnesota, Rhode Island, and Wisconsin. A bipartisan coalition of 41 attorneys general told the CFTC that sports-related event contracts should remain under state authority, arguing platforms like Kalshi and Polymarket operate as unregulated sportsbooks.

The CFTC separately proposed new event-contract rules on June 10, with a comment deadline of July 27. The proposed framework would expand the types of outcomes that can be traded on regulated exchanges, further blurring the line between derivatives markets and prediction platforms.

Market Scale and Momentum

The volume surge in perpetual derivatives suggests significant demand. SpaceX pre-IPO perpetual contracts generated approximately $3.2 billion in volume and $390 million in open interest between May 17 and June 10 across eight exchanges. Binance captured $2.1 billion of SpaceX perp volume during that period. If Kalshi’s early $5 billion pace sustains, annualized onshore perpetual volume could reach $90 billion. The global perpetual futures market achieved $61.7 trillion in volume during 2025, representing 29% year-over-year growth, while US onshore-regulated perps currently hold $154 billion in annual notional volume.

CME’s lawsuit will test whether the CFTC’s classification of perpetual contracts as futures products can withstand legal challenge, and whether Dodd-Frank’s swap framework applies. The outcome will shape whether platforms like Kalshi, Coinbase, and others can continue expanding onshore derivatives offerings or face reclassification and operational constraints.
