On December 4, Polymarket launched its U.S. app, enabling domestic trading for the first time under its amended CFTC-approved designation. This reentry follows a 2022 $1.4 million fine for operating an unregistered derivatives exchange and a November 2024 beta relaunch. In July 2025, Polymarket acquired licensed platform QCX to facilitate its U.S. comeback. The regulated relaunch is expected to attract institutional interest to blockchain-based prediction markets.
