A U.S. Army soldier faces federal charges for allegedly using classified intelligence to trade on Polymarket, marking the first insider trading case tied to a prediction market.
The indictment in the Southern District of New York names Gannon Ken Van Dyke. Prosecutors say Van Dyke accessed classified details about "Operation Absolute Resolve," the campaign to capture Venezuelan leader Nicolás Maduro, and used it to bet on Polymarket.
He wagered about $33,000 on 13 contracts tied to U.S. involvement in Venezuela or Maduro losing power by January 31, 2026. After the operation ended on January 3, he reportedly earned around $409,881.
"Prediction markets are not a haven for using misappropriated confidential or classified information for personal gain," said U.S. Attorney Jay Clayton. "The defendant allegedly violated the trust placed in him... That is clear insider trading and is illegal under federal law."

The indictment describes a cover-up. After the media reported suspicious trading, Van Dyke tried to delete his Polymarket account and changed the email addresses for his crypto exchange accounts.
"Widespread access to prediction markets is a relatively new phenomenon, but federal laws protecting national security information fully apply," said Acting Attorney General Todd Blanche.
What this means for the industry
This case immediately impacts prediction market operators and their brokers. By charging Van Dyke under the Commodity Exchange Act, the DOJ is reinforcing CFTC jurisdiction and treating prediction market contracts as financial derivatives — not recreational wagers.
That's a legal distinction platforms have been addressing carefully, and the government has now made its position explicit. The ruling also strengthens the position of regulated operators like Kalshi, which has long argued it operates under the same insider trading framework as traditional exchanges.

Less-regulated platforms now face pressure to demonstrate comparable compliance infrastructure. Surveillance and monitoring are urgent concerns. All platforms and brokers must show they can detect and flag suspicious activity.
The DOJ credited Polymarket's cooperation, signaling that regulators expect platforms to act as enforcement partners, not just infrastructure. Whether insider trading rules apply to prediction markets was theoretical until now.
The Van Dyke case ends that debate and raises a practical issue: how enforcement will work in an industry without uniform compliance standards.
