Soldier Trades on Classified Intel, CFTC Sneaks in Through the Back Door

2026-08-25

Gannon Ken Van Dyke, a US soldier, allegedly made over $400,000 using information he shouldn't have had. He traded event contracts on Polymarket related to the removal of Venezuelan President Nicolás Maduro—an operation he was directly involved in planning. The trades happened between 30 December 2025 and 2 January 2026. He bought more than 436,000 "Yes" shares in the "Maduro Out by January 31, 2026?" contract using his Polymarket handle "Burdensome-Mix."

The US authorities charged him with fraud in April. Straightforward: he had nonpublic classified information. He used it to trade. He made serious money.

What's getting legally messy now is the regulatory turf war.

Van Dyke's lawyers just filed opposition to the CFTC's attempt to file an amicus brief—a "friend of the Court" intervention—in his criminal case at the US District Court for the Southern District of New York. The CFTC is already pursuing its own civil case against him. Van Dyke's team sees the amicus move as underhanded. Their language is sharp: "The CFTC is no sheep 'friend of the Court' here. It is a regulatory wolf, with its own case against Mr. Van Dyke that it refuses to pursue itself. Rather, like a true coursing predator, the CFTC seeks to advance its own interests through the back door of an amicus brief instead of facing its own case against Mr. Van Dyke head on."

The core issue underneath all this is whether event contracts on prediction markets like Polymarket are "swaps" subject to CFTC jurisdiction. Van Dyke's defence argues they're not. The CFTC disagrees and wants the court to hear it. A federal judge has already stayed the CFTC's civil case pending the outcome of the criminal proceedings.

This case is the first insider trading prosecution involving prediction markets. That alone makes it significant. Lawmakers and critics have pointed to it repeatedly as evidence of potential manipulation on platforms like Kalshi and Polymarket. The stakes extend far beyond one soldier's bad decision.

The legal classification matters because it determines regulatory territory. The CFTC filed its own amicus brief in the US Court of Appeals for the Sixth Circuit asserting exclusive jurisdiction over prediction markets. This filing is part of a larger campaign to protect CFTC authority from what the agency sees as state encroachment on its turf.

The charges against Van Dyke invoke the "Eddie Murphy Rule"—prohibitions on government employees and others with access to confidential government information using that information to trade futures, options, or swaps. The first two counts rest on this framework. The question of whether prediction market contracts qualify as swaps under that rule has produced conflicting rulings across federal circuit courts.

Van Dyke has pleaded not guilty to all charges. A criminal trial could begin in late 2026 or early 2027. The CFTC's civil case sits paused, waiting for the criminal process to finish.

The prediction market industry watches closely. How courts classify event contracts will shape what platforms can do, who can trade, and which agency gets to call the shots.
