Polymarket's location verification systems, US advertising practices, and onboarding procedures for its US platform are under review by the Commodity Futures Trading Commission (CFTC), according to a Reuters report citing two unnamed sources. This scrutiny follows earlier probes by the CFTC and Justice Department in 2025 into whether Polymarket honored terms of a 2022 settlement, which were subsequently closed. The new review marks continued regulatory attention to the prediction market platform's compliance with US requirements.
