U.S. Special Forces Soldier Charged in First-Ever Prediction Market Insider Trading Case

Gannon Ken Van Dyke, a U.S. Army Master Sergeant and Special Forces communications specialist stationed at Fort Bragg, was arrested and indicted by the Justice Department's Southern District of New York after allegedly using classified intelligence about the U.S. military capture of Venezuelan President Nicolás Maduro to place bets on the prediction market platform Polymarket, netting more than $409,000 in illegal profits. Van Dyke is the first person in U.S. history to face federal charges for insider trading on a prediction market, according to court filings and statements from the Department of Justice.

The Details

Van Dyke, who served as a communications specialist supporting the Joint Special Operations Command, placed approximately $33,034 across 13 trades on Polymarket between December 27, 2025 and January 26, 2026, according to the indictment filed in SDNY. The trades centered on contracts asking whether Maduro would be removed from power by January 31, 2026 — a question Van Dyke allegedly knew the answer to in advance through his access to classified operational information.

The classified intelligence concerned Operation Absolute Resolve, the U.S. military operation that resulted in Maduro's capture on January 3, 2026, when he was apprehended and flown to the United States. The operation involved the USS Iwo Jima, according to court documents.

Prosecutors allege Van Dyke moved aggressively in the hours before the raid. On January 2, 2026, beginning at approximately 8 p.m. ET, he executed three large transactions — placing bets that would pay out if Maduro was removed from office before the end of the month, according to the indictment.

Three days after the operation concluded, on January 6, Van Dyke contacted Polymarket and requested that his account be deleted, citing the loss of access to his email, according to the DOJ. The platform did not comply. Instead, Polymarket flagged the trading activity as suspicious and referred the matter to federal authorities. The platform cooperated fully with the DOJ investigation.

Van Dyke faces five counts in the SDNY indictment: unlawful use of confidential government information, theft of nonpublic government information, commodities fraud, wire fraud, and monetary transactions derived from unlawful activity. The case has been assigned to U.S. District Judge Margaret M. Garnett. If convicted on all counts, Van Dyke faces a maximum sentence of up to 60 years in federal prison.

U.S. Attorney Jay Clayton, whose office brought the charges, addressed the case directly. 'Prediction markets are not a haven for using misappropriated confidential or classified information for personal gain,' Clayton said in the DOJ statement. Polymarket also issued a statement: 'Insider trading has no place on Polymarket. Today's arrest is proof the system works.'

President Donald Trump offered his own comparison. 'That's like Pete Rose betting on his own team,' Trump said, according to multiple reports.

Context

The case is the first of its kind in the United States. While securities markets have long been subject to insider trading statutes, prediction markets — which allow users to bet on the outcomes of real-world events — have existed in a more ambiguous regulatory environment. The Van Dyke indictment signals that federal prosecutors are prepared to pursue insider trading charges in that space under existing fraud and theft statutes.

The case is not isolated internationally. Israel recently arrested military reservists on similar allegations — placing bets on Polymarket tied to outcomes of Israeli military operations where they had prior knowledge — according to NBC News and Axios. Several U.S. states have also moved to ban state employees from trading on prediction markets using confidential government information, though a uniform federal framework for prediction market regulation has not yet been enacted.

What's Next

The case will proceed before U.S. District Judge Margaret M. Garnett in the Southern District of New York, per court records. Van Dyke's arraignment and subsequent pretrial schedule have not been publicly announced as of the time of publication.

The DOJ's willingness to bring this prosecution under commodities fraud and wire fraud statutes — rather than waiting for prediction-market-specific legislation — may signal how prosecutors intend to approach similar cases going forward, though no official DOJ policy statement on prediction market regulation has been issued.
