A U.S. Army Special Forces master sergeant named Gannon Ken Van Dyke faces arrest and federal charges for wagering on the prediction platform Polymarket with sensitive details about the apprehension of Venezuela's ex-president Nicolás Maduro. As a key participant in the mission's strategy and implementation, Van Dyke reportedly earned $409,881 from his activities.
The Department of Justice states that Van Dyke set up his Polymarket profile on December 26, 2025, and placed 13 wagers concerning Maduro between December 27 and January 2. He selected the affirmative side for multiple markets, such as those predicting U.S. military presence in Venezuela before January 31, 2026, Maduro's removal by that date, a potential American invasion of Venezuela by the deadline, and President Trump's activation of war powers regarding Venezuela by the end of January. Authorities took Maduro and his spouse into custody on January 3.
Van Dyke is said to have staked a total of $33,034 on these predictions, yielding returns exceeding tenfold his investment. On the very day of Maduro's detention, he extracted his funds from Polymarket, transferred them to an overseas cryptocurrency storage, and later moved the proceeds into a fresh internet-based investment platform.
Following the high-profile detention, news emerged about an unidentified bettor who pocketed close to $500,000 just before the public revelation, sparking worries over gains from privileged defense intelligence. Prosecutors allege Van Dyke attempted to obscure his involvement: after media coverage of possible internal trading surfaced, he requested Polymarket to erase his profile, providing the untrue excuse of no longer having access to the registration email. Additionally, he updated the email tied to his digital currency holdings to one bearing no connection to his identity.
Authorities have indicted Van Dyke on three violations of the Commodity Exchange Act, each punishable by up to a decade behind bars. He also faces one count of wire fraud, which could result in a 20-year term, along with a single charge of illegal financial transfer, carrying a potential 10-year sentence.
Platforms for event-based betting continue to grapple with issues of unauthorized trading on confidential data, and this case marks another example. In a recent development, rival site Kalshi penalized three aspiring politicians for suspected advantages in bets tied to their elections. Candidates Matt Klein from Minnesota and Ezekiel Enriquez from Texas each received penalties under $1,000 plus trading bans lasting as long as five years. Virginia's Mark Moran, however, is subject to further sanctions, a five-year exclusion, and a penalty surpassing $6,000.
