Three insider trading investigations have been approved: the CFTC is investigating Polymarket, Biden's pardon, the Iran war, and the Google contract.

According to Odaily Planet Daily, the U.S. Commodity Futures Trading Commission (CFTC) has previously secretly approved three insider trading investigations into Polymarket contracts related to Biden's pardon, the Iran war, and Google. In May, CFTC Chairman Michael Selig approved an investigation into contracts related to Biden's pardon after a trader profited over $300,000 from the market. That same month, the CFTC approved an investigation into contracts related to the Iran war after a group of suspicious accounts were reported to have profited $2.4 million with an approximately 98% win rate. In July, the CFTC further launched an investigation into Google-related Polymarket contracts, focusing on individuals who may have used non-public information about Google's 2025 search rankings for trading. The U.S. Attorney's Office for the Southern District of New York is also conducting a parallel investigation. Polymarket has stated that it will refer the matter to law enforcement and cooperate with the investigation.
