Polymarket is intensifying its effort to rebuild and expand its U.S. presence, launching a U.S. mobile app for real-money sports betting while stepping up marketing through social media influencers and pursuing partnerships with MLB, sports teams, CNBC and CNN, according to CoinDesk. The push follows the platform’s exit from the U.S. market after a 2022 settlement with the CFTC, the U.S. derivatives regulator, and comes after a later federal investigation that included a raid on CEO Shayne Coplan’s home ended in 2025 with no charges filed. The moves indicate an effort to restore trust and legitimacy in a tightly regulated market for event-based trading and sports betting.
