Polymarket’s launch of its U.S. app marks its regulated reentry after a 2022 fine, supported by its acquisition of licensed platform QCX earlier in 2025.
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.
