CFTC charges soldier in first insider trading case on Polymarket

A North Carolina Army service member is accused of turning classified details about a U.S. operation into a six-figure win on Polymarket, giving regulators their first insider-trading case tied to event contracts and a fresh test of how to police a market built for speed.

The Commodity Futures Trading Commission said Gannon Ken Van Dyke used nonpublic information about an operation to capture Nicolás Maduro and Cilia Flores, an effort identified in the filing as Operation Absolute Resolve, to buy more than 436,000 “Yes” shares of the Polymarket contract asking whether Maduro would be out by January 31, 2026. The agency said Van Dyke traded under the handle “Burdensome-Mix” and made more than $404,000 in profits.

The complaint marks a new enforcement line for a market that has grown around real-world events rather than company earnings or stock prices. The CFTC said the case was the first insider-trading charge involving event contracts and the first time it had used the so-called Eddie Murphy Rule for misuse of government information. It seeks restitution, disgorgement, civil penalties, trading and registration bans, and a permanent injunction.

The case also shows why prediction markets have become so hard to police. Trades can be placed in seconds, the underlying information may come from military or political channels instead of corporate boardrooms, and the asset itself is a contract on a future outcome, not a share of stock. That makes suspicious timing easier to hide in the noise of fast-moving public events, even when the profit is obvious after the fact.

Polymarket and Kalshi have both tightened insider-trading-related rules and screening tools under pressure, but lawmakers and critics still question whether those safeguards can catch the kind of conduct regulators describe in the Van Dyke case. The scrutiny has intensified as the companies build their Washington presence. CNBC reported that Kalshi said it held about 90% of U.S. market share and that Kalshi and Polymarket spent nearly $1 million combined on federal lobbying in 2025.

For regulators, the deeper problem is not just one soldier’s trades. It is proving when a prediction market participant had access to illicit information, how that information traveled, and whether the platform’s own records are enough to trace the edge. Van Dyke’s case suggests the old insider-trading playbook is being stretched to fit a market where the bets, the data trail, and the legal questions all look different.
