CME Takes CFTC to Court Over the Legal Status of U.S. Perpetual Crypto Futures

Coinbase has rolled out U.S.-style perpetual crypto products on its CFTC-regulated derivatives exchange, starting with micro Bitcoin and micro Ethereum contracts. The contracts track spot prices, embed leverage and are available for 24/7 trading—bringing the dominant instrument in global leveraged crypto trading into the U.S. regulated market. Perpetuals account for the bulk of crypto derivatives activity. Coinbase data show that, under certain measures, perpetuals represent more than 90% of total derivatives volume, while derivatives overall make up roughly 80% of all cryptocurrency trading. For years, that activity largely sat offshore, with U.S. participants often relying on VPN access. That changed on May 29, when the CFTC approved KalshiEX to list BTCPERP, a Bitcoin spot-pegged perpetual, and issued a policy statement laying out a pathway for other venues to offer similar products. On June 12, the CFTC followed with rules that let licensed designated contract markets remove expiration dates from certain perpetual-style crypto futures—turning them into true perpetual contracts if specified conditions are met. The regulatory approach is now under direct legal challenge. On June 18, CME sued the CFTC and its Chair, Michael Selig, in the U.S. District Court for the District of Columbia, asking the court to vacate the Kalshi approval order and the accompanying policy statement. CME argues that perpetual contracts meet the Commodity Exchange Act's definition of swaps, and that the Chair effectively rewrote that definition without following the broader swap regulatory framework set by Congress. CME's position is that treating perpetuals as swaps would trigger significantly tighter oversight, including dealer registration, higher capital requirements and more frequent reporting—changes that would likely shift pricing influence and licensing advantages back toward incumbent regulated venues such as CME. The CFTC has pushed back sharply. A spokesperson said CME's decision to sue regulators runs counter to the administration's pro-innovation stance, framed the action as an attempt to avoid competition and said the agency will seek dismissal in court. Commercial stakes are large. CME's complaint says Kalshi has already launched more than ten crypto perpetual contracts under the approval, with related volume exceeding $1 billion. The CFTC is also defending its authority elsewhere, including a lawsuit filed against Kentucky in late June over oversight of contract markets. The federal case remains in its early stages, with no ruling yet—leaving U.S. venues offering "American-style perpetuals" operating under a legal foundation that could be reshaped by the courts. Two "perpetual" structures, one market In the U.S., products marketed as perpetuals currently fall into two distinct legal designs. A true perpetual has no expiration date. With no physical delivery to pull prices toward spot, it uses periodic funding payments between longs and shorts to keep prices aligned: when the contract trades above spot, longs typically pay shorts; when it trades below spot, shorts pay longs. Kalshi's BTCPERP is structured as a true perpetual with no expiry. Coinbase's version uses a five-year, long-dated futures structure plus hourly interest accrual and twice-daily funding-rate settlements to mimic perpetual price behavior while fitting within existing futures rules. The CFTC's June conversion framework is designed to allow those long-dated futures to shed expiration over time and become true perpetuals—one reason the term "perpetual futures" now covers two legally different products in the U.S. Why perpetuals matter—and where risks concentrate Crypto trades continuously, without weekend closes or monthly expiry cycles. Perpetuals were built for that environment: non-expiring leveraged exposure that can be opened, adjusted or held at any time, supporting speculation, hedging, market-making inventory management and basis trades in a single instrument. Exchanges also like perpetuals because liquidity concentrates in one contract instead of fragmenting across multiple maturities, typically improving depth. That concentration can also intensify feedback loops. When positioning becomes lopsided, funding rates and forced liquidations can transmit price moves faster than in traditional futures curves with multiple expiries. U.S. platforms are pursuing several regulated pathways at once. Kalshi has listed true perpetuals spanning Bitcoin, Ethereum, XRP and other tokens. Coinbase has launched perpetual-style futures domestically and, on May 29, opened a compliant channel through its subsidiary platform, Deribit, to give U.S. investors access to global perpetual and options liquidity. Deribit is a major crypto options venue; Bitcoin options open interest topped $31 billion at the end of May. On the same day, CME moved its expiring crypto futures and options to 24/7 trading, matching spot-market weekend availability. CME reported $3 trillion in notional crypto derivatives volume last year and an average daily contract volume of about 407,200 so far this year. With multiple routes emerging, contract terms, leverage limits, liquidation rules, collateral requirements and price references differ across venues. The result is fragmented liquidity, margin and open interest, with collateral generally not portable—reducing capital efficiency. Funding, liquidations and the fight over price discovery Funding rates are often described as fees, but function more like a real-time indicator of leveraged long/short imbalance, constantly pulling the perpetual toward spot. If leveraged longs push perpetual prices above spot, arbitrageurs can short the perpetual while buying Bitcoin spot, Bitcoin ETFs or traditional futures to collect funding—activity that can raise spot demand and influence ETF flows, while also affecting CME futures basis. At scale, open interest in the perpetual market can feed back into the spot market it is designed to track. Deep, regulated U.S. perpetual markets could develop their own local funding-rate curve—an observable, regulatable barometer of leverage sentiment—distinct from offshore benchmarks. A persistent spread between U.S. and offshore funding would highlight differences in user mix, leverage ceilings and cross-border capital mobility, helping traders infer whether price action reflects directional speculation or hedging demand. Leverage also makes liquidation dynamics central. When margin falls below maintenance requirements, exchanges automatically close positions: liquidating longs creates market sell pressure, liquidating shorts creates market buy pressure. Concentrated liquidations can trigger cascades, especially in a 24/7 market with high leverage and fragmented liquidity. Regulated venues can mitigate some operational risks through segregation of client funds, transparent terms, continuous surveillance, standardized liquidation procedures and access to U.S. legal remedies. Regulation does not remove volatility, funding costs or leverage risk, and cannot guarantee that liquidations will not amplify adverse moves. The next competitive edge: cross-market collateral A key battleground is likely to be cross-category collateral and margin portability—letting traders net risk across spot, ETFs, futures, options and perpetuals. Today, collateral is split across spot accounts, futures brokers, clearinghouses, broker-dealers and offshore exchanges. That fragmentation adds cost because margin in one pocket cannot readily support hedges in another. A Bitcoin ETF position, for example, cannot directly margin a perpetual short; CME futures and local perpetuals typically sit in separate margin pools. Coinbase Derivatives, working with Nodal Clear (a clearinghouse under Deutsche Börse's EEX Group), has applied to allow USDC—Circle's stablecoin—to be posted as margin for U.S. futures, with Coinbase Custody Trust holding the USDC. The proposal is awaiting 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 crypto-native collateral without converting into fiat. That kind of capital efficiency may matter more than how many tokens a venue lists, since large platforms can add new contracts quickly. Two tests now loom over the U.S. perpetual rollout: whether locally regulated perpetuals absorb, lead or amplify the next major Bitcoin volatility event, and whether the courts ultimately classify these instruments as futures or swaps—a decision that could either cement the compliant ecosystem built over the past half year or impose the stricter swap regime CME is arguing for.
