The U.S. Commodity Futures Trading Commission (CFTC) stated that U.S. stock perpetual contracts have been approved for trading, though stock market circuit breakers and trading halts may still hinder position liquidation and exit. The CFTC stated on November 3 that U.S. stock perpetual futures can begin trading on eligible regulated exchanges. Such contracts have no fixed expiration date, but holders remain subject to stock market circuit breakers and trading halt rules, which may prevent position liquidation during market disruptions. Filings and proposals from Kalshi and Coinbase show that trading hours for perpetual contracts are restricted and must comply with the same regulatory halt requirements as the underlying equities.
