Prediction Markets Explainer

A U.S. soldier involved in the military operation to capture Venezuelan President Nicolás Maduro has been charged with using classified information about the mission to win more than $400,000 in an online betting market. Federal officials unsealed the indictment Thursday. Gannon Ken Van Dyke was part of the work to capture Maduro in January and used his access to classified information to make money on the prediction market site Polymarket, the federal prosecutor’s office in New York said. He has been charged with unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud, and making an unlawful monetary transaction.
