A U.S. special forces soldier has pleaded not guilty in federal court in New York to charges that he used classified information about the mission to capture former Venezuelan leader Nicolás Maduro to win more than $400,000. Gannon Ken Van Dyke is accused of using the information on the prediction market Polymarket. He entered the plea on Tuesday after he was charged with the unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud and making an unlawful monetary transaction. The case comes during heavy scrutiny on prediction markets, which allow people to trade or wager on almost anything.
