Summary

In April 2026, the U.S. Department of Justice and CFTC charged Gannon Ken Van Dyke, an active-duty U.S. Army Special Forces master sergeant, with using classified information about a U.S. military operation to capture Venezuelan leader Nicolás Maduro to place profitable bets on the prediction market platform Polymarket. The case is the first U.S. criminal insider-trading prosecution involving prediction market event contracts, and it has prompted Polymarket to expand its trade-monitoring infrastructure. Van Dyke has pleaded not guilty and the case is pending trial; the entity being profiled — Polymarket itself — was not charged with wrongdoing but is implicated as the venue through which the alleged scheme was executed.
