Van Dyke Pleads Not Guilty to Charges Over Maduro Raid Bets

U.S. Army master sergeant Gannon Ken Van Dyke pleaded not guilty in Manhattan federal court on April 28 to charges alleging he used nonpublic information tied to the January raid that captured Venezuelan leader Nicolás Maduro and his wife, Cilia Flores, to place prediction-market bets. Reuters and CBS News / AP reported prosecutors say Van Dyke used advance knowledge of the operation to wager on Polymarket before the raid became public.

The Details

Van Dyke, 38, entered the plea before U.S. District Judge Margaret Garnett in Manhattan federal court, according to Reuters. When asked for his plea, Reuters reported he told the court, "Not guilty, your honor." CBS News / AP separately reported the plea was entered April 28 in federal court in New York. The case centers on allegations that he traded on confidential government information linked to the Maduro operation.

Reuters reported prosecutors allege Van Dyke placed about $33,000 in Polymarket bets between Dec. 27, 2025 and Jan. 2, 2026. Those bets, according to Reuters, predicted that Maduro would be out of office and that U.S. forces would enter Venezuela. Prosecutors say the positions later returned more than $400,000, turning a narrow run of trades into the central financial claim in the indictment.

CBS News / AP reported Van Dyke is 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. Reuters and The Guardian both reported prosecutors say Van Dyke was involved in the planning and execution of the January raid itself, linking the alleged bets to a military operation rather than to public rumor or market chatter.

The government has framed the case as a test of whether criminal insider-trading theories can apply to prediction markets. In a statement quoted by CBS News / AP after the case was announced, U.S. attorney Jay Clayton said, "Prediction markets are not a haven for using misappropriated confidential or classified information for personal gain." CBS News / AP also reported that Polymarket said it flagged the suspicious trading and turned the activity over to authorities, adding an early compliance step before prosecutors filed charges.

Van Dyke's defense has signaled it will challenge both the allegations and the legal theory behind them. Reuters reported defense counsel Mark Geragos told reporters after the hearing, "Mr. Van Dyke is an American hero, somebody who is charged unfortunately with something that is not a crime." That defense argument tracks the dispute described by Reuters, which said prosecutors are treating the conduct as insider trading while Van Dyke's lawyers say the indictment does not charge a crime.

Context

Reuters reported the prosecution is the first time the U.S. Justice Department has brought insider-trading charges involving a prediction market. That places the case in a new legal category for federal prosecutors, who are applying fraud and confidential-information theories to bets placed on a platform built around public-event contracts.

The underlying raid gives the charges a second layer of scrutiny. Reuters and The Guardian reported prosecutors say Van Dyke was not an outsider guessing at military plans, but someone involved in planning and carrying out the January operation that captured Maduro and Flores. CBS News / AP, Reuters and The Guardian all treated the charges as allegations that have not been tested at trial.

The sourcing record also shows how the investigation developed outside the government. CBS News / AP reported Polymarket identified the unusual trading activity and referred it to authorities, a detail that places the prediction platform inside the origin of the inquiry rather than solely as the venue where the bets were placed. That sequence matters because the public record described in the brief begins with market activity, then moves to a criminal case built around how that activity was allegedly informed.

What's Next

Reuters reported Van Dyke was released on a $250,000 bond after the plea hearing. Reuters also reported his next court date is June 8, setting the next public milestone as the case moves through its early pretrial phase in Manhattan.

The legal fight is likely to focus on both the facts and the statute. Reuters reported the defense plans to challenge the indictment, while prosecutors are pressing ahead with charges that treat the alleged use of confidential government information for prediction-market trading as criminal conduct.

For now, the case remains at the pretrial stage. The gaps in the reporting record are also clear: the full indictment and underlying evidence were not independently retrieved in the reporting summarized in the fact brief, and the charges against Van Dyke remain allegations that have not been proven in court.
