The U.S. CFTC has added 3 new insider trading investigations into Polymarket: involving Biden's pardons, the Iran war, and Google

The U.S. Commodity Futures Trading Commission (CFTC) has previously secretly approved at least three insider trading investigations related to Polymarket trading, involving contracts related to Biden's pardons, the Iran war, and Google-related events. The relevant investigation documents were obtained by WIRED through the Freedom of Information Act.

Among them, CFTC Chairman Michael Selig approved an investigation into contracts related to Biden's pardons in May, after a trader had profited over $300,000 in the relevant market; in the same month, the CFTC also approved an investigation into Iran war contracts, after a group of suspicious accounts was reported to have profited $2.4 million with a win rate of about 98%. In July, the CFTC further initiated an investigation into Google-related Polymarket contracts, focusing on individuals who may have traded using non-public information regarding Google's 2025 search rankings. The Southern District Attorney's Office in New York is also conducting a parallel investigation.

It is currently unclear whether the aforementioned accounts are connected to previously investigated individuals. Polymarket stated that the company would refer the relevant matters to law enforcement and cooperate with the investigation. As the prediction market rapidly expands, U.S. regulators are clearly intensifying their scrutiny of insider trading and market manipulation.
