- Gannon Ken Van Dyke, a Special Forces master sergeant at Fort Bragg, was indicted Thursday on wire fraud and Commodity Exchange Act charges.
- Prosecutors say he used classified intel on Operation Absolute Resolve — the raid that captured Venezuelan leader Nicolas Maduro — to place bets on Polymarket.
- He wagered over $33,000 across 13 bets between Dec 27, 2025 and Jan 2, 2026, profiting $409,881 the day of the raid.
- Van Dyke allegedly moved winnings to a foreign crypto vault, then an online brokerage, and asked Polymarket to delete his account.
- Polymarket tipped off the DOJ, citing its new market integrity rules — the same rules rolled out last month.
- Wire fraud carries up to 20 years in prison. The CFTC filed a parallel civil complaint.
A US Army Special Forces master sergeant was indicted Thursday on charges he used classified military information to win more than $400,000 on prediction market platform Polymarket. Federal prosecutors in Manhattan say Gannon Ken Van Dyke, 37, exploited his access to Operation Absolute Resolve — the US operation that captured Venezuela’s Nicolas Maduro — to place 13 bets totaling over $33,000, then cashed out $409,881 on the day of the raid.
Polymarket Insider Trading Case: The Indictment Details
Van Dyke, a Fort Bragg-based Special Forces soldier since 2008, was “involved in the planning and execution of Operation Absolute Resolve,” prosecutors said in a statement, “and had access to sensitive, nonpublic, classified information about that operation.” He placed his 13 bets between December 27, 2025 and January 2, 2026, all taking an affirmative position on whether the US would act militarily against Maduro.
He withdrew the $409,881 profit the day of the raid and moved it first into a foreign cryptocurrency vault, then into an online brokerage account, according to the Southern District of New York indictment. Prosecutors allege Van Dyke took steps to conceal his identity once speculation about the oddly timed trades began circulating online, and asked Polymarket to delete his account using a phony excuse.
How Polymarket Caught the Classified Intel Bet
In a post on X, Polymarket said it was the one that flagged the trades to federal authorities. “Last month, we published our enhanced market integrity rules to combat insider trading. When we identified a user trading on classified government information, we referred the matter to the DOJ & cooperated with their investigation,” the company wrote. “Insider trading has no place on Polymarket. Today’s arrest is proof the system works.”
The tip-off lands the platform in rare territory: a crypto-native prediction market actively helping federal prosecutors build an insider trading case. It also gives Polymarket a marketing win at a moment when rival Kalshi has been fighting its own integrity battles — on Wednesday, Kalshi said it had suspended and fined three candidates for political office for trading on their own elections. In February, Kalshi banned a MrBeast editor for trading on YouTube-related markets.
Trump, Pete Rose, and the Politics of Prediction Markets
Asked about federal employees betting on prediction markets, President Donald Trump first asked whether Van Dyke had wagered that the US would catch Maduro. When told he had, Trump compared it to “Pete Rose betting on his own team” — a reference to the Cincinnati Reds manager banned from baseball for gambling. “If he bet against his team, that would be no good,” Trump added, an answer that muddied the legal stakes but captured how fast this case has gone political.
CFTC Chairman Michael Selig, who has publicly defended prediction markets as “valuable to society,” took a harder line on Van Dyke. “Anyone who engages in fraud, manipulation, or insider trading in any of our markets will face the full force of the law,” he said, noting the soldier “took action that endangered US national security and put the lives of American service members in harm’s way.” The CFTC filed a parallel civil complaint against Van Dyke in federal court.
What This Means for Prediction Markets in 2026
Insider trading has been the central compliance headache for prediction markets since they started scaling. Kalshi has already suspended political candidates and banned influencers. Polymarket now has a federal indictment of a US service member to point to as proof its rules bite. The industry’s argument to regulators — that prediction markets aggregate real information and can police themselves — just got its strongest test case.
The penalty is severe. Wire fraud alone carries up to 20 years in prison, and Van Dyke faces multiple felony counts on top of that. No defense attorney was listed in the court docket. For federal employees, contractors, and service members with access to classified information, the signal is clear: the days of anonymous crypto-paid wagers on your own operations are over. The receipts stay on-chain — and so does the evidence.
