Polymarket insider trading case heads to trial

Written by Heidi Cuthbert Published Jun 10, 2026, 3:13 AM

A Manhattan federal court has scheduled a December 7 trial for Gannon Van Dyke, the US Army soldier accused of using classified information to profit from trades on prediction market platform Polymarket.

Federal prosecutors allege that Van Dyke used non-public military intelligence linked to a January operation involving Venezuelan President Nicolás Maduro to place a series of successful wagers on the platform.

Court filings claim Van Dyke turned approximately US$33,000 into more than US$410,000 through 13 Venezuela-related bets placed over a seven-day period.

The 38-year-old faces three counts of violating the Commodity Exchange Act, as well as wire fraud and unlawful monetary transaction charges, and has pleaded not guilty to all allegations.

According to prosecutors, Van Dyke also attempted to conceal the activity by requesting the deletion of his Polymarket account after the trades were completed.

The case is being closely watched because authorities have described it as the first insider trading prosecution in the United States involving a prediction market, potentially setting a precedent for how existing financial and commodities laws apply to event-based trading platforms.

Beyond the criminal proceedings, Polymarket continues to face scrutiny from lawmakers and regulators in the United States and abroad, including congressional inquiries related to Venezuela-linked markets, investigations involving South Korean users and a separate civil complaint filed by the US Commodity Futures Trading Commission.
