CFTC Brings First Insider-Trading Case in Prediction Markets Against U.S. Army Service Member

U.S. regulators have opened a new front in policing prediction markets, charging a U.S. Army service member with insider trading tied to event contracts and raising fresh legal and national security questions about trading on government-linked outcomes. Key takeaways: - The CFTC's action is its first insider-trading case involving event contracts. - Regulators allege an Army service member used classified information to trade for profit. - Polymarket wagers allegedly relied on nonpublic details of a U.S. military operation. On April 23, 2026, the Commodity Futures Trading Commission said it filed a civil complaint against Gannon Ken Van Dyke of North Carolina, alleging he traded prediction market contracts using classified information connected to a U.S. operation involving Nicolás Maduro. The agency said the matter is the first time it has charged insider trading involving event contracts, and the first time it has invoked the so-called "Eddie Murphy Rule" to bring a case based on the alleged misuse of government information. CFTC Chairman Mike Selig wrote on X: "I've been crystal clear: anyone who engages in insider trading in any of our markets will face the full force of the law." The CFTC is seeking restitution, disgorgement, civil monetary penalties, trading bans, and a permanent injunction. The "Eddie Murphy Rule" refers to Section 4c(a)(4) of the Commodity Exchange Act, which prohibits government personnel, including service members, from using nonpublic government information in prediction markets and other markets under the CFTC's jurisdiction. Separate DOJ case amplifies security concerns In its filing, the CFTC alleged Van Dyke used nonpublic details tied to "Operation Absolute Resolve" to buy more than 436,000 "Yes" shares on Polymarket in a contract tied to Maduro's removal by Jan. 31, 2026. The CFTC said the trading produced more than $404,000 in profits. The Department of Justice separately alleged Van Dyke profited about $409,881 from related prediction market activity. A DOJ indictment unsealed in Manhattan federal court alleges he used classified information obtained through his role in "Operation Absolute Resolve" to place Polymarket trades ahead of any public disclosure. Prosecutors said Van Dyke accessed classified, nonpublic national defense information, participated in operational planning, and violated confidentiality obligations, creating national security risks by positioning himself to profit from an anticipated outcome. Selig added: "The CFTC won't tolerate insider trading in our markets, and our Division of Enforcement will continue to vigilantly police our markets for any illegal actions." CFTC Director of Enforcement David I. Miller said: "The defendant abused that trust by misappropriating extremely sensitive information regarding U.S. military operations, and by doing so, placed the lives and security of our service members at risk." Federal prosecutors said the alleged conduct aligns with parallel criminal charges filed in the Southern District of New York.
