Coinbase has opened U.S.-regulated gold and silver futures to 24/7 trading, extending the always-on market structure of crypto into traditional commodity derivatives. The change applies to gold and silver futures listed on Coinbase Derivatives, a CFTC-registered designated contract market. The exchange lists gold futures with a 1 troy ounce contract size and silver futures with a 50 troy ounce contract size, giving eligible traders regulated exposure to precious metals through smaller futures contracts.
