U.S. regulators are once again investigating Polymarket for potential violations of the settlement agreement reached in 2022.

According to Reuters, citing two sources familiar with the matter, the U.S. Commodity Futures Trading Commission (CFTC) is again investigating Polymarket for potential violations of its 2022 settlement agreement, focusing on whether the platform has taken sufficient measures to block U.S. users from accessing its overseas main platform. The agency previously closed a similar probe in 2025 without filing charges. This latest review is part of a broader investigation launched by the CFTC earlier this year, covering Polymarket’s controls for verifying customer locations and its U.S. advertising campaigns. One source said the review centers on the company’s past controls and processes. The CFTC is also examining Polymarket’s customer onboarding procedures and consumer protection measures for its U.S. platform. Under the 2022 settlement, Polymarket agreed to stop serving U.S. users. In 2024, the CFTC and the U.S. Department of Justice launched separate related probes, and the FBI searched CEO Shayne Coplan’s New York residence that November. In July 2025, Coplan announced both investigations had concluded. Afterward, the company acquired a CFTC-licensed derivatives exchange and gradually rolled out its U.S. platform by the end of that year. Polymarket has previously stated it has improved its controls, explicitly prohibiting users from using tools like VPNs to bypass geographic restrictions, and has mechanisms to monitor misconduct and block restricted users from accessing its overseas platform. In April this year, U.S. prosecutors charged a service member with using insider information to place bets on Polymarket’s overseas platform, profiting $400,000; the indictment alleged he used a VPN to bypass restrictions. The defendant has denied the charges, and Polymarket said at the time it had referred the matter to relevant authorities.
