CME Takes CFTC to Court Over Perpetual Crypto Contracts Pathway

Coinbase has rolled out U.S.-style perpetual futures on its CFTC-regulated derivatives exchange, starting with micro Bitcoin and micro Ethereum contracts. The products track spot prices, embed leverage features and are designed for 24/7 trading—bringing into the U.S. a contract format that dominates global crypto leveraged activity. Perpetuals account for the bulk of crypto derivatives trading. Coinbase data show that, by some measures, perpetual contracts represent more than 90% of total derivatives volume, while derivatives overall account for roughly 80% of all cryptocurrency trading. For years, most perpetual trading sat outside U.S. regulatory reach, with many U.S. participants accessing offshore venues through VPNs. That changed on May 29, when the CFTC approved KalshiEX to list BTCPERP, a perpetual tied to Bitcoin's spot price, and issued a policy statement laying out a pathway for other exchanges to offer similar products. On June 12, the CFTC adopted additional rules allowing licensed designated contract markets to remove expiration dates from certain perpetual-style crypto futures and convert them into true perpetual contracts if specified conditions are met. The framework underpinning those approvals is now being challenged in federal court. On June 18, CME filed suit in the U.S. District Court for the District of Columbia against the CFTC and Chair Michael Selig, seeking to overturn both the Kalshi approval order and the accompanying policy statement. CME argues the agency effectively rewrote Congress's statutory definition of swaps under the Commodity Exchange Act and sidestepped the swap regulatory regime. CME's central claim is that perpetual contracts meet the legal definition of swaps. If courts agree, platforms offering these instruments could face significantly tighter requirements, including dealer registration, higher capital standards and more frequent reporting—changes that would tilt market structure back toward established derivatives incumbents. The complaint also highlights process concerns, noting that Chair Selig approved Kalshi's application in a single day. The CFTC has pushed back sharply, with a spokesperson saying CME's litigation posture conflicts with the administration's pro-innovation stance, accusing the exchange of resisting fair competition and calling the lawsuit meritless. The agency said it will seek dismissal. Commercial stakes are substantial. CME's filing says Kalshi has launched more than ten additional crypto perpetual contracts under the approval, with related trading volume exceeding $1 billion. Separately, the CFTC has also sued the state of Kentucky in late June in a bid to clarify jurisdiction over contract markets. With no rulings yet, U.S. exchanges offering American-style perpetual products are operating under a legal regime that could be reshaped by the courts. In practice, "perpetual futures" now refers to two distinct U.S. structures. Kalshi's BTCPERP is a true perpetual with no expiry. Coinbase's version uses a five-year, long-dated futures contract paired with hourly interest accrual and twice-daily funding settlements to mimic perpetual price behavior while fitting within existing futures rules. The CFTC's June conversion plan would allow long-dated structures to progressively eliminate expirations and become true perpetuals. Perpetuals were built for crypto's nonstop market. With no delivery month selection, they allow continuous positioning for speculation, hedging, market-making inventory management and basis trading. Exchanges favor the model because liquidity concentrates in a single contract rather than dispersing across expiries, boosting depth. The trade-off is that concentrated open interest can magnify the impact of funding and liquidation flows, accelerating moves compared with traditional futures curves. U.S. offerings also diverge from offshore norms. Kalshi has listed true perpetuals spanning Bitcoin, Ethereum, XRP and other tokens. Coinbase is offering perpetual-style futures domestically and also opened a compliant access channel on May 29 that routes U.S. investors to global perpetual and options liquidity through its subsidiary platform, Deribit. Deribit is a major crypto options venue; Bitcoin options open interest topped $31 billion at the end of May. On the same day, CME shifted its expiring crypto futures and options to 24/7 trading to better match spot market hours. CME said its crypto derivatives posted $3 trillion in notional trading volume last year, and average daily volume of about 407,200 contracts this year. Across these channels, contract design choices vary widely—leverage limits, liquidation rules, collateral requirements and price reference benchmarks differ by venue. As compliant pathways multiply, liquidity, margin and open interest risk becoming fragmented, and collateral typically cannot be used interchangeably across platforms, reducing capital efficiency. Funding rates sit at the center of the pricing mechanism. More than a fee, funding reflects the real-time balance of leveraged longs versus shorts and helps pull perpetual prices toward spot. When perpetual prices trade above spot due to heavy leveraged long demand, arbitrageurs can short the perpetual and buy spot Bitcoin, Bitcoin ETFs or traditional futures to capture funding, which can influence spot order flow, ETF creations/redemptions and even the basis in CME futures. Deep, regulated U.S. perpetual markets could develop their own domestic funding-rate curve—an observable, supervisable signal of leverage appetite—distinct from offshore benchmarks. A persistent gap between U.S. and offshore funding would highlight differences in user mix, leverage constraints and cross-border capital mobility, helping markets interpret whether moves are driven by directional speculation or hedging. Leverage also raises liquidation risk. If margin falls below maintenance thresholds, exchanges liquidate positions automatically. Liquidated longs become market sells; liquidated shorts become market buys. In a 24/7 market with high leverage and fragmented liquidity, liquidations can cascade, turning a single move into a chain reaction. Regulated venues can reduce certain operational and conduct risks through segregation of client funds, transparent contract terms, continuous surveillance, standardized liquidation procedures and U.S. legal remedies. Regulation does not eliminate volatility, funding costs or the core risks of leverage, and compliant products can still generate large liquidation-driven price swings unrelated to fundamentals. Industry competition is increasingly focused on collateral flexibility. The next major advantage may be the ability to use cross-category collateral and share margin across spot, ETFs, futures, options and perpetuals. Today, capital is split across spot accounts, futures brokers, clearinghouses, broker-dealers and offshore exchanges, creating friction because margin in one pool generally cannot support hedges elsewhere. For instance, a Bitcoin ETF position typically cannot be posted as margin for a perpetual short, and CME futures margin is separate from margin tied to local perpetual offerings. Coinbase Derivatives, working with Nodal Clear (a clearing house under Deutsche Börse's EEX Group), has applied to allow USDC—Circle's stablecoin—to be used as margin for U.S. futures, with Coinbase Custody Trust holding the USDC. The proposal awaits CFTC approval. If cleared, it would be the first compliant use of a stablecoin as margin in the U.S. futures market, enabling traders to post margin using crypto-native collateral without converting to fiat. Ultimately, capital efficiency—not the sheer number of newly listed contracts—may prove decisive, since major venues can list assets quickly. Two inflection points stand out: the next episode of sharp Bitcoin volatility, which will test whether domestic perpetuals absorb, lead or amplify price action; and the court's final decision on whether these contracts are legally futures or swaps. That ruling could either cement the compliant perpetual ecosystem built over the past six-plus months or force the market into the stricter swap framework CME is advocating.
