CFTC and soldier dispute Polymarket case in court
A US soldier accused of using nonpublic information on Polymarket is challenging the CFTC’s attempt to weigh in on his criminal case as both sides clash over prediction-market rules.
A US soldier accused of making more than $400,000 through trades on Polymarket is fighting an attempt by the Commodity Futures Trading Commission to enter his criminal case. The dispute centers on whether event contracts on prediction markets should fall under the agency’s authority.
The soldier, Gannon Ken Van Dyke, is alleged to have used nonpublic information to trade on the platform. A judge has already paused the CFTC’s separate civil case against him, but the regulator now wants to file a brief in the criminal matter and address the defense’s legal arguments.
Clash over market definition
Van Dyke’s lawyers objected in a Monday filing in the US District Court for the Southern District of New York. They argued against the CFTC’s request to submit an amicus brief and pressed the court to reject the agency’s effort to influence the case from the sidelines.
One of the defense arguments is that event contracts traded on platforms such as Polymarket are not swaps and therefore do not sit within the CFTC’s remit. The regulator is seeking permission to present its view on that question, which could matter beyond this case if the court addresses how prediction markets are classified.
What the dispute could affect
The fight highlights the tension between prediction markets and traditional derivatives rules. Polymarket has drawn scrutiny because its contracts are tied to real-world outcomes, a structure that has prompted questions about whether they should be treated as regulated financial instruments.
The criminal case and the paused civil action are now moving on separate tracks. For the CFTC, the issue is not only the alleged trading conduct but also the broader legal framing of prediction markets and whether its oversight should extend to them.
If the court allows the agency to weigh in, the filing could add pressure to a defense built around jurisdiction. If it does not, the case may proceed with the regulator on the outside as the parties argue over the reach of commodities law.
