United States soldier Gannon Ken Van Dyke has been arrested and charged for placing bets on prediction marketplace Polymarket using classified information he had access to related to the capture of former Venezuelan president Nicolás Maduro. The US Army Special Forces master sergeant, who was directly involved with the planning and execution of the operation, allegedly made $409,881 in profits.
According to the Department of Justice, Van Dyke created a Polymarket account around December 26, 2025 and made 13 bets related to Maduro from December 27 to January 2. He took the “Yes” position on several Polymarket wagers, including “US Forces in Venezuela… by January 31, 2026,” “Maduro out by… January 31, 2026, “Will the US invade Venezuela by January 31” and “Trump invokes War Powers against Venezuela by… January 31.” The US military captured Maduro and his wife on January 3.
Van Dyke allegedly bet a total of $33,034 and made over ten times that amount from his winnings. He withdrew his money from Polymarket on the day Maduro was captured and then sent it to a foreign crypto vault before depositing it to a new online brokerage account.
Shortly after Maduro’s capture, reports came out about how an anonymous gambler made almost half a million dollars before it was announced, raising concerns that someone had profited off insider military knowledge. The Justice Department says Van Dyke tried to cover his tracks. After reports about the potential insider bets were published, he allegedly asked Polymarket to delete his account, falsely claiming that he lost access to the email he used. He also changed the email address linked to his crypto account to another one not associated with his name.
Van Dyke has been charged with three counts of violation against the Commodity Exchange Act, with each one carrying a max sentence of 10 years in prison. He has also been charged with one count of wire fraud with a max penalty of 20 years in prison, as well as one count of unlawful monetary transaction with a max sentence of 10 years.
Prediction marketplaces have been struggling with insider trading problems, and this is far from the first incident. Recently, Kalshi took action against three political candidates, accusing them of insider trading related to their campaigns. Matt Klein of Minnesota and Ezekiel Enriquez of Texas face a fine of less than $1,000 and suspensions of up to five years. Meanwhile Mark Moran of Virginia faces disciplinary action, a five year suspension and a fine of more than $6,000.
