DOJ and CFTC file first prediction-market insider-trading case over Maduro contracts
Federal prosecutors in the Southern District of New York and the Commodity Futures Trading Commission filed parallel criminal and civil insider-trading charges on Tuesday, May 12, in what Sidley describes as the first prediction market insider trading case. The charges involve event contracts traded on Polymarket tied to Nicolas Maduro's removal from power in Venezuela, which allegedly generated more than $400,000 in profits. On or about December 26, 2025, the defendant created and funded a Polymarket account and began trading the Maduro-linked contracts. The joint DOJ-CFTC action tests the application of fraud statutes and the Commodity Exchange Act to crypto-native prediction markets, with DLA Piper flagging compliance takeaways for sector operators.
Polymarket must now absorb the precedent that its crypto-native infrastructure is within the CFTC's manipulation-enforcement perimeter under the Commodity Exchange Act. Any failure to build out surveillance capable of flagging misappropriation-based trading will leave the platform exposed as a repeat venue in SDNY's expanding misappropriation theory.
Becomes the third major CFTC enforcement action this week targeting prediction market platforms after the no-action letter conditions and Selig's league outreach, signaling that the agency is simultaneously clearing market structure and policing misconduct.
