The CFTC is once again investigating prediction market platform Polymarket, which previously reached a settlement with the regulator in 2022, agreeing to block US users from accessing its offshore platform. This investigation is part of a broader inquiry into Polymarket launched by the agency earlier this year, focusing on whether Polymarket violated the 2022 settlement agreement, as well as its customer targeting controls and advertising activities in the United States. The CFTC is also reviewing Polymarket's US platform, launched last December, particularly its customer registration process and safeguards. Previously, the CFTC investigated Polymarket's compliance with the agreement in 2024 but withdrew related measures in July 2025.
