Defense Directive: New Memo Targets Insider Bets on Prediction Markets

Military service members and defense civilians in New England and across the country now face stricter guidance regarding personal financial activities. A new directive from the top of the Department of Defense warns that betting on military outcomes using nonpublic information could expose troops to greater risk by revealing operational details to foreign adversaries. The change aims to tighten the link between personal finance and national security protocols.

Defense Secretary Pete Hegseth issued the warning in a memo dated October 20, which was published by CBS News on October 22. The document was distributed to senior Pentagon leadership, Combatant Command leaders, and directors of Defense Department field activities. The memo carries the subject line, “Do Not Compromise Military Operations for Personal Financial Gain,” signaling a formal shift in how the department views insider trading within the context of war and intelligence.

The core argument of the memo is that financial transactions act as observable signals. Hegseth wrote that enemies monitor movements in prediction markets, and when a service member or intelligence professional places a bet based on military outcomes, they create a detectable pattern. According to the secretary, hostile foreign intelligence services can aggregate and correlate these signals to anticipate American movements, targets, and timing. The memo emphasizes that the safety of service members often relies on the element of surprise, which such wagers can undermine.

Hegseth stressed that the prohibition extends to all financial platforms, not just specific prediction sites. The guidance covers traditional betting services as well as emerging prediction markets such as Polymarket and Kalshi. The rule applies to any financial transaction informed by nonpublic information, regardless of whether that information is classified or unclassified. This broad scope ensures that even minor leaks of unclassified data through betting activity are addressed under the new directive.

The memo highlights a specific recent incident to illustrate the risks. In April, a U.S. Army soldier was arrested and charged with using confidential information to make bets on Polymarket. The soldier wagered on the timing of the military’s capture of Venezuelan President Nicolás Maduro, resulting in $410,000 in profits. This case serves as a primary example of how nonpublic knowledge can translate into significant financial gain while potentially compromising operational security.

Further evidence of the trend was cited in an August report by the Anti-Corruption Data Collective. The group identified 152 suspicious wallets that placed longshot bets on military and defense markets. These accounts won a combined total of $8 million, suggesting that the practice may be more widespread than previously acknowledged. The report’s findings support the Defense Secretary’s concern that the market is becoming a target for exploitation by those with insider knowledge.

The directive frames the issue as a matter of force protection rather than just financial regulation. Hegseth stated that the men and women who carry the flag into harm’s way deserve a force that protects them, not one that exposes them for personal gain. By treating betting signals as potential intelligence leaks, the memo elevates the issue from a personal finance matter to a strategic military concern.

While the memo provides clear guidance, questions remain about enforcement and the precise definition of nonpublic information in the context of rapid market changes. The directive does not detail specific penalties for violations, nor does it clarify how the Department will monitor transactions across all financial platforms. For now, the guidance serves as a formal warning to all defense personnel to exercise caution in any financial activity related to military operations.
