In a groundbreaking legal case that marks the first insider trading prosecution against a prediction market in U.S. Department of Justice history, 38-year-old U.S. Army Special Forces Master Sergeant Gannon Ken Van Dyke has pleaded not guilty to charges that he exploited classified military intelligence about a covert operation targeting Venezuelan President Nicolás Maduro to earn more than $400,000 in illegal betting profits.
Van Dyke made his first court appearance at a federal arraignment in New York on Tuesday, one week after federal prosecutors unsealed a multi-count indictment outlining the alleged scheme. Clad in a dark tailored suit and black shirt, he took a seat at the defense table alongside his legal team, which is led by high-profile defense attorney Mark Geragos—recently known for his work on the legal team representing Sean “Diddy” Combs. When U.S. District Court Judge asked Van Dyke to enter his plea, he clearly responded: “Not guilty, your honour.”
Following the arraignment, Judge granted Van Dyke conditional release on a $250,000 secured bond, with strict travel and supervision conditions. He was ordered to surrender his U.S. passport, and the judge ruled that Van Dyke, who is currently on approved leave from military service, will remain under court-ordered supervision while residing in North Carolina. His approved travel is restricted to limited regions within North Carolina, the Southern District of New York, and California for legal proceedings and case-related meetings.
In comments to reporters waiting outside the courthouse, Geragos pushed back forcefully against the federal government’s allegations, arguing that the conduct prosecutors have accused his client of does not qualify as a criminal offense under U.S. law. Geragos went on to describe Van Dyke as a decorated “American hero” who has devoted nearly 98% of his adult life to exemplary military service to the United States. The attorney confirmed that he intends to file formal legal motions “shortly” that will challenge both the grand jury indictment itself and the federal court’s jurisdiction over the case.
The origins of the case date back to a classified U.S. military covert action codenamed Operation Absolute Resolve, which targeted Maduro for removal in early January 2026. According to the unsealed indictment, Van Dyke—who has served on active duty in the U.S. Army since 2008 and earned promotion to master sergeant in Special Forces in 2023—signed multiple binding non-disclosure agreements barring him from sharing or profiting from classified information related to sensitive operations. Prosecutors allege he played a direct role in planning and executing the Maduro seizure operation, which included months of pre-positioning military assets, coordinated air strikes, and an extensive network of on-the-ground intelligence operatives in the region.
Between December 27, 2025, and January 2, 2026, Van Dyke leveraged his inside knowledge of the operation’s timeline and objectives to place at least 13 separate bets on Polymarket, a crypto-based decentralized prediction market, the indictment claims. He invested a total of roughly $33,934 of his own money across bets predicting the timing of the U.S. military incursion into Venezuela and Maduro’s removal from power. When Maduro was taken into U.S. custody in early January as planned, Van Dyke’s bets paid out a total of more than $409,800 in winnings, prosecutors allege.
Following the payout, court documents outline a series of alleged attempts by Van Dyke to conceal the illegal profits and his identity. According to the DOJ, Van Dyke first transferred the majority of his winnings to an interest-bearing offshore cryptocurrency “vault” to hide the funds from regulators. He then changed the registered email address associated with his cryptocurrency exchange account to a new, unregistered anonymous address. In mid-January, he transferred the full balance of winnings plus accumulated interest—totaling approximately $444,209—to a newly created personal brokerage account. After independent online investigators began highlighting the suspicious large bet in early January, Van Dyke also deleted his Polymarket account in an attempt to cover his tracks, prosecutors say.
The case has drawn intense public and regulatory scrutiny in large part because of the anonymous nature of blockchain-based prediction markets. After online analysts noticed the unusually large, perfectly timed bet on Maduro’s capture in early January, widespread public backlash and speculation erupted over the identity of the bettor and whether classified information had been exploited. Polymarket CEO Shayne Coplan has confirmed that the platform’s internal compliance team flagged the suspicious activity early on and voluntarily notified federal law enforcement of the potential violation. While the account linked to the bet was initially anonymous, identified only by a string of alphanumeric characters on the blockchain, investigators were able to trace the account back to Van Dyke because he used a personal email address to register the account.
In addition to the criminal charges brought by the DOJ, Van Dyke also faces a separate civil insider trading lawsuit brought by the U.S. Commodity Futures Trading Commission (CFTC), the independent federal regulator that oversees commodities and futures trading. The criminal charges against Van Dyke include unlawful use of confidential government information for personal gain, theft of non-public government data, commodities fraud, wire fraud, and unlawful monetary transaction. If convicted on all counts, he faces decades of federal prison time and substantial financial penalties.
This case also comes amid growing bipartisan concern over the rising risk of U.S. government officials and military personnel with access to classified information exploiting crypto prediction markets to profit off sensitive policy, military, and political events, leading to expanded calls for tighter regulatory oversight of these blockchain-based platforms.
