A US Special Forces Soldier Was Charged for Betting on His Own Classified Operation

The Department of Justice unsealed an indictment on April 23 charging Gannon Ken Van Dyke, a U.S. Army Master Sergeant with the Special Forces, with using classified government information to profit on prediction market bets. Van Dyke allegedly turned approximately $33,000 into more than $409,000 by wagering on Polymarket contracts tied to the U.S. military operation to capture Venezuelan President Nicolas Maduro. It is one of the most dramatic insider trading cases the young prediction market industry has ever produced — and prosecutors say it was illegal under federal law.

What the Indictment Alleges

According to the DOJ, Van Dyke was involved in planning and executing Operation Absolute Resolve starting around December 8, 2025. That operation ultimately resulted in U.S. special forces apprehending Maduro and his wife at a residence in Caracas, Venezuela in the predawn hours of January 3, 2026. While in possession of classified, nonpublic information about the timing and nature of that operation, Van Dyke allegedly created a Polymarket account on December 26, 2025 and began making bets.

Between December 27 and January 2, Van Dyke made approximately 13 trades, all taking the “YES” position on contracts including “U.S. Forces in Venezuela by January 31, 2026,” “Maduro out by January 31, 2026,” “Will the U.S. invade Venezuela by January 31,” and “Trump invokes War Powers against Venezuela by January 31.” After the President publicly announced the successful operation on January 3, Polymarket resolved several of those contracts to “YES” and Van Dyke collected his winnings.

He then allegedly sent most of the proceeds to a foreign cryptocurrency vault before depositing them into a newly created brokerage account. On January 6, he asked Polymarket to delete his account, falsely claiming he had lost access to the associated email address, and changed the registered email on his cryptocurrency exchange account to one not in his name — steps prosecutors describe as deliberate efforts to conceal his identity.

The Charges He Faces

Van Dyke, age 38, was 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. The case was assigned to U.S. District Judge Margaret M. Garnett in the Southern District of New York. The CFTC, which regulates prediction markets, filed a parallel civil complaint. If convicted on all counts, Van Dyke faces the possibility of decades in prison.

U.S. Attorney for the Southern District of New York Jay Clayton stated in the announcement that prediction markets “are not a haven for using misappropriated confidential or classified information for personal gain” and that what Van Dyke allegedly did was “clear insider trading” and illegal under federal law. FBI Director Kash Patel called out the conduct as a betrayal of Van Dyke’s fellow soldiers. Polymarket, for its part, said it had identified the suspicious trading, alerted the DOJ, and cooperated with the investigation. The company issued a statement saying “Insider trading has no place on Polymarket.”

Why This Case Is Accelerating Congressional Pressure

The Van Dyke case is not the first time unusual trading patterns in prediction markets have raised insider trading concerns related to U.S. government actions. Reports emerged after the Venezuela operation about suspicious trading by an anonymous user who profited roughly $400,000 on Maduro-related contracts — that user turned out to be Van Dyke. Earlier, similar questions arose around trading on Polymarket ahead of U.S. and Israeli military actions involving Iran.

These episodes have given bipartisan ammunition to lawmakers pushing to rein in prediction markets. In March, Senator Jeff Merkley introduced the STOP Corrupt Bets Act, which would prohibit event contracts on sports, government actions, and military operations. Senators John Curtis and Adam Schiff introduced a separate bipartisan bill targeting sports prediction contracts. The Van Dyke indictment arrived just as Congress was debating these measures — and it is exactly the kind of real-world example critics of the industry have been citing to argue that unregulated access to these markets creates genuine national security risks.

For sports bettors, the case matters because the regulatory and legislative environment around prediction market platforms is being shaped in real time by exactly these kinds of events. The debate over whether Kalshi and Polymarket should be regulated more like traditional sportsbooks — and whether state laws should apply to them — is closely linked to concerns about the insider trading vulnerabilities this case exposed.
