US Defense Secretary Warns Pentagon Personnel Against Insider Trading on Prediction Markets
Defense Secretary Pete Hegseth warned Pentagon staff in an October 20 letter against using nonpublic information on prediction markets, citing enemy monitoring of trading signals. It follows charges against a soldier for $409,000 in alleged Polymarket profits and a report of 152 suspicious accounts with 97.2% win rates yielding $8M profits. Prediction platforms now carry explicit national security flags.
SCCG Take — Prediction market operators should expect intensified compliance demands around military and geopolitical contracts to prevent insider signals from compromising operations.
US Defense Secretary Pete Hegseth has issued a warning to military personnel and Department of Defense employees against using nonpublic information for trades on prediction markets. The letter dated October 20 prohibits financial transactions based on classified details, whether executed directly or indirectly, and extends to sports betting platforms.
Hegseth cited risks that foreign adversaries could exploit trading patterns to infer US military intentions. The directive arrives amid broader examination of prediction markets that allow bets on geopolitical and military developments.
“Our Enemies Watch Movements in These Markets”
Hegseth wrote that foreign intelligence services monitor these platforms for signals. “Our enemies watch movements in these markets,” he stated. He explained that a trade on a military outcome by service members or civilians creates detectable patterns that hostile actors can combine with other data to predict operations, targets, and timing.
Such activity increases risk to American personnel, the letter notes. It also undermines focus. “We are restoring lethality, discipline, and singular focus on fighting and winning our nation’s wars, and nothing should distract us from that sacred mission. Not entertainment. Not a payout,” Hegseth wrote.
Cases Highlighting Insider Trading Risks
The warning follows charges against Master Sgt. Gannon Ken Van Dyke, a US Army Special Forces soldier. Prosecutors allege he used classified information from planning a military operation to capture Venezuelan leader Nicolás Maduro and generated approximately $409,000 in profits on Polymarket through trades worth around $33,000. The charges remain unproven in court.
The Anti-Corruption Data Collective separately flagged 152 accounts linked to US military events. Those accounts showed a 97.2% win rate and produced $8 million in profits from $2 million in trades, according to reporting by GamblingNews.
These examples underscore the specific security vulnerabilities prediction markets can present when nonpublic information enters the system.
