  • US Soldier Charged in First Insider Trading Case on Prediction Markets
    April 24, 2026, 10:59 PM EDT. A US special forces soldier, Gannon Ken Van Dyke, faces insider trading charges for allegedly exploiting classified knowledge of the January raid that captured Venezuelan President Nicolás Maduro.
