Fact Check

The core claim is supported by the DOJ press release and, most importantly, the indictment at https://www.justice.gov/usao-sdny/media/1437781/dl. The indictment says Gannon Ken Van Dyke was an active-duty U.S. Army Master Sergeant with Special Forces, participated in Operation Absolute Resolve to capture Nicolás Maduro, and made about $409,881 from Polymarket bets related to Maduro's removal and U.S. action in Venezuela. The DOJ press release at https://www.justice.gov/usao-sdny/pr/us-soldier-charged-using-classified-information-profit-prediction-market-bets confirms the criminal charges. The CFTC press release at https://www.cftc.gov/PressRoom/PressReleases/9217-26 independently confirms a parallel insider-trading case based on the same alleged facts. CoinDesk and CBS both align with these primary records. The main nuance is phrasing: the official materials emphasize he was charged, and the detailed filing supports that he was arrested in connection with those charges, while calling him a U.S. soldier/Master Sergeant with Special Forces rather than the exact headline wording.

Summary

The U.S. Department of Justice has publicly charged U.S. Army Special Forces sergeant major Gannon Ken Van Dyke over alleged insider trading on Polymarket tied to Nicolás Maduro-related bets. Prosecutors say Van Dyke used classified intelligence to profit more than $400,000, and Polymarket said it identified the suspicious trades, reported them to law enforcement, and cooperated fully with investigators. The case is being described as the first major criminal insider trading case involving prediction markets. Earlier reporting and civil allegations from the CFTC said investigators tied more than $33,000 in Polymarket wagers to the January operation and cited profit figures ranging from more than $400,000 to more than $409,000. Prior reports also linked the activity to wallet 0x31a5 and alleged that funds were withdrawn the same day and moved through an offshore crypto account.
