Crypto perpetuals hit U.S. markets; CME sues CFTC

Perpetual crypto futures — no-expiry contracts that use recurring funding payments to link prices to spot markets — have started trading on U.S. regulated venues following a sequence of CFTC actions in late May and June. The CFTC approved KalshiEX’s Bitcoin perpetual on May 29 and on June 12 issued a conditional conversion path allowing designated contract markets to remove expiration dates from long-dated crypto contracts.

Coinbase began offering perpetual-style futures on its CFTC-regulated derivatives exchange, launching nano Bitcoin and Ethereum contracts that track spot prices, embed leverage and trade 24/7. Kalshi has self-certified additional crypto perpetuals and reported that trading in its contracts has exceeded $1 billion.

Two legal and product structures now operate under the perpetual label in the U.S. market. Kalshi’s BTCPERP is a true no-expiry perpetual that uses continuous funding between longs and shorts. Coinbase’s contracts are structured as long-dated futures with five-year expirations and an hourly funding rate settled twice daily; the CFTC’s conversion route allows those long-dated contracts to shed expirations over time and become genuine no-expiry perpetuals.

On June 18, CME filed suit in the U.S. District Court for the District of Columbia asking the court to vacate the Kalshi approval and the CFTC’s policy statement. CME’s complaint argued the agency “overrode Congress’s definition of a swap and sidestepped the regulatory framework” in treating perpetuals as futures rather than as swaps under the Commodity Exchange Act. The complaint says classifying perpetuals as swaps would bring them under dealer registration, capital and reporting requirements.

The CFTC responded to the filing by characterizing the lawsuit as “lawfare” and calling the complaint “frivolous,” and it described the agency’s action as an opening for regulated U.S. trading of a product previously concentrated offshore.

Perpetual contracts use funding payments between long and short holders to keep contract prices close to spot. When a perpetual trades above spot, longs typically pay shorts; when it trades below spot, shorts typically pay longs. Arbitrage strategies can involve shorting a perpetual while buying spot or ETFs to capture funding, and scaling that trade can move spot flows, ETF creations and basis relationships.

Market participants and exchanges have adjusted to the onshore launch. CME moved its dated crypto futures and options to 24/7 trading the same day the CFTC announced the conversion route. Exchanges and clearinghouses are also pursuing collateral and margin changes: Coinbase Derivatives and clearinghouse Nodal Clear, part of Deutsche Börse’s EEX Group, have proposed accepting Circle’s USDC as margin for U.S. futures, with Coinbase Custody Trust as custodian and CFTC approval pending. If approved, that would be the first regulated use of a stablecoin as margin in the U.S. futures system.

Liquidity, margin and collateral remain fragmented across spot accounts, futures commission merchants, clearinghouses, brokerage accounts and offshore platforms, and some market participants are building tools to let traders use collateral more efficiently across venues.

The federal court case will determine whether perpetuals are futures on regulated U.S. exchanges or swaps subject to a different statutory regime. That legal classification will affect which firms can offer the products and which registration, capital and reporting rules apply. The operational performance of U.S. perpetuals will be tested as domestic markets trade through periods of sharp Bitcoin volatility while the litigation proceeds.
