Pentagon Chief Cracks Down on Prediction Market Bets
Defense Secretary Pete Hegseth has ordered military staff to stop using inside knowledge for wagering, citing new risks to operational security.

The Pentagon has officially warned its workforce against betting on military outcomes using nonpublic information, a move aimed at closing a perceived security gap in modern warfare. Defense Secretary Pete Hegseth issued a directive on October 20 that instructs service members and civilian employees to avoid placing wagers on platforms like Polymarket and Kalshi when they possess knowledge that has not been made public. The core concern is that these financial transactions create detectable patterns that foreign adversaries can exploit to anticipate American military actions.
The directive 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.” This communication marks a formal institutional response to the growing intersection of finance and military intelligence. It signals that the Department of Defense now views prediction markets as a potential vector for operational exposure, not just a niche hobby for a few individuals.
Hegseth’s message is direct and urgent. He argues that enemies actively monitor movements in these markets. When a service member, intelligence professional, or department civilian engages in a financial transaction based on a military outcome, they generate a signal. Hostile foreign intelligence services can then aggregate and correlate these signals. This data allows opponents to predict movements, targets, and timing with greater accuracy. The secretary emphasized that the safety of troops often relies on the enemy’s lack of foresight.
The stakes are framed in terms of force protection. Hegseth wrote that the men and women carrying the flag deserve a force that protects them. He contrasted this ideal with the current risk, describing a scenario where personnel are exposed to the enemy for personal gain. The memo asserts that the prohibition applies to all financial platforms. This includes traditional betting services and emerging prediction markets. The rule covers any financial transaction informed by nonpublic information, whether that data is classified or unclassified.
This guidance follows a series of events that highlighted the vulnerability of military secrets to market mechanics. In April, a US Army soldier was arrested and charged with using confidential information. The officer allegedly made $410,000 in bets on Polymarket regarding the timing of the military’s capture of Venezuelan President Nicolás Maduro. This incident provided a concrete example of how nonpublic data can translate into personal profit, while simultaneously creating a footprint for intelligence agencies to track.
Further scrutiny came in August with a report from the Anti-Corruption Data Collective. The group identified 152 suspicious wallets that placed longshot bets on military and defense markets. These accounts collectively won approximately $8 million. The report suggested that a pattern of unusual activity existed, reinforcing the idea that insiders or those with close proximity to military decision-making might be leveraging their positions. These findings likely contributed to the momentum behind the new memo.
The timing of the announcement is significant for the broader defense sector. It occurs as prediction markets gain mainstream popularity and become increasingly integrated into financial ecosystems. By targeting all financial platforms, the Department of Defense aims to create a clear standard of conduct. This prevents confusion over which specific apps or websites are off-limits. The blanket prohibition simplifies compliance for the vast number of personnel across the military and civilian workforce.
The next steps involve implementing this policy across all levels of command. Leaders are expected to communicate the new rules to their teams and monitor for compliance. Training materials may be updated to reflect the specific risks associated with digital wagering. The directive serves as both a warning and a clarifying instruction. It tells personnel that their financial activities are no longer private matters when they intersect with military operations. The goal is to ensure that the pursuit of personal financial gain does not come at the cost of operational security or troop safety.
