U.S. Army Master Sergeant Gannon Ken Van Dyke pleaded not guilty Tuesday to five federal charges in Manhattan federal court, stemming from a series of Polymarket bets that turned $33,000 into more than $404,000. Prosecutors describe this as the first insider-trading case ever filed against a prediction-markets trader.
Defense Signals Challenge to Indictment
The 38-year-old special forces soldier appeared before U.S. District Judge Margaret M. Garnett, with high-profile defense attorney Mark Geragos leading the team alongside Zach Intrater. Geragos told reporters outside the courtroom he plans to challenge the validity of the indictment itself — a notable strategy given the case's landmark status. Judge Garnett released Van Dyke on a $250,000 bond and set the next pretrial conference for June 8. Travel is restricted to parts of North Carolina, New York, and California, where Van Dyke has family.
Van Dyke faces charges including unlawful use of confidential government information, theft of non-public government information, commodities fraud, wire fraud, and making an unlawful monetary transaction. The charges stem from bets placed between December 27 and January 2 on Polymarket that Maduro would soon leave office and U.S. forces would enter Venezuela. Both events were priced as unlikely at the time, producing the windfall when Operation Absolute Resolve captured Maduro on January 3.
CFTC Deploys 'Eddie Murphy Rule' for First Time
The Commodity Futures Trading Commission has filed parallel civil charges, making this a dual federal-criminal and civil enforcement action against a single retail prediction-markets trader. The CFTC complaint marks the first time the agency has invoked the so-called “Eddie Murphy Rule” — a provision of the Commodity Exchange Act named after the 1983 film Trading Places, which prohibits government employees from using nonpublic government information in markets under CFTC jurisdiction. “This case marks the first time the CFTC has charged insider trading involving event contracts,” said CFTC Director of Enforcement David I. Miller when the complaint was unsealed.
Cover-Up Trail Documented
According to the indictment, after winning the bets, Van Dyke transferred funds to a foreign cryptocurrency vault, moved proceeds into a newly created online brokerage account, asked Polymarket to delete his account, and changed the email address on his crypto exchange account to one not in his name. A photograph allegedly tied to the operation — Van Dyke “on what appears to be the deck of a ship at sea, at sunrise, wearing U.S. military fatigues, and carrying a rifle” — was uploaded to his Google account after the raid. Polymarket said it flagged Van Dyke's trading to authorities and cooperated with the investigation. Rival Kalshi had previously blocked Van Dyke under its ID requirements, per Reuters. The June 8 pretrial conference will set the schedule for what is likely to become a test case for federal courts handling insider trading on event-contract platforms.
