Overview
- Prosecutors say Master Sgt. Gannon Ken Van Dyke used classified operational information to place 13 bets on Polymarket that netted more than $400,000 and then tried to destroy evidence of the trades.
- Van Dyke pleaded not guilty in April and was released on a $250,000 personal recognizance bond while he is on leave from the Army.
- His defense team told a Manhattan court they will file a motion to dismiss the indictment by July 31 and the judge set a tentative trial date for Dec. 7 with the next status conference on Sept. 28.
- The Justice Department charged Van Dyke with theft of nonpublic information, commodities fraud, wire fraud, unlawful monetary transactions and related offenses in what observers call the first federal insider‑trading prosecution tied to a prediction market.
- The case has pushed regulators to use blockchain tracing and other tools to follow crypto flows, prompted CFTC involvement, and could lead Congress to consider clearer rules for Polymarket and similar platforms.
