Hegseth Bans Military Bets on Prediction Markets to Protect Operational Secrets

Defense Secretary Pete Hegseth issued a directive on October 20 prohibiting military personnel from using nonpublic information to place bets on prediction markets. The memo, titled Do Not Compromise Military Operations for Personal Financial Gain, was distributed to senior Pentagon leaders, Combatant Command heads, and Defense Department field activity directors. CBS News published the document on October 22.

Hegseth stated that financial transactions tied to military outcomes create a signal that adversaries track. He wrote that hostile foreign intelligence services can aggregate, correlate, and exploit this data to anticipate American movements, targets, and timing. The memo asserts that enemy knowledge of upcoming operations often puts service members at risk. Hegseth argued that troops who carry the flag into harm's way deserve a force that protects them rather than one that exposes them for personal financial gain.

The prohibition applies to all financial platforms, including traditional betting services and specific prediction markets such as Polymarket and Kalshi. Department personnel are barred from making any financial transaction informed by nonpublic information. This restriction covers both classified and unclassified data, ensuring that no internal knowledge leaks into public trading volumes or odds movements.

The directive follows a high-profile criminal case from April 2026. A US Army soldier was arrested and charged with using confidential information to make $410,000 in bets on Polymarket. Those wagers targeted the timing of the military's capture of Venezuelan President Nicolás Maduro. The case provided concrete evidence that individual service members could profit from internal military timelines.

Broader concerns regarding market manipulation emerged 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. Together, those accounts won a combined $8 million. The report suggested that coordinated or informed betting could distort market prices and reveal operational details to outside observers.

Hegseth framed betting as a threat to military judgment in his communication to commanders. He warned that personal financial stakes in military outcomes can compromise operations. The memo instructs leaders to ensure their units avoid transactions that might signal intent to foreign adversaries. The directive aims to close the gap between internal knowledge and public financial activity.

The memo emphasizes that financial gain must not come at the cost of operational security. Service members are instructed to review their trading activities against the new standard. The policy remains in effect immediately for all covered personnel. Hegseth's office will monitor compliance through existing reporting channels.
