Pentagon bans insider bets on wars
The Defense Secretary has urged troops to avoid prediction markets to prevent leaks.
By Noor Haddad ·

The Department of Defense has issued a formal directive telling its personnel to stop using private knowledge to place wagers on future military events. This new guidance aims to close a potential gap in security where financial markets could reveal operational intentions to rival nations.
The warning was distributed in a memo dated October 20 and released to the public by CBS News the following day. Defense Secretary Pete Hegseth sent the message to senior leadership at the Pentagon, heads of Combatant Commands, and directors of various field activities. The subject line of the document was direct, reading, “Do Not Compromise Military Operations for Personal Financial Gain.”
Hegseth explained the core risk in his writing, noting that hostile intelligence services actively monitor these digital betting platforms. When a service member or civilian employee places a bet based on information they should not have, it creates a visible signal. Adversaries can aggregate and correlate these signals to predict American military movements, targets, and timing. The secretary emphasized that the safety of troops often relies on the element of surprise, and he argued that soldiers deserve a force that protects them rather than one that exposes them to danger for the sake of personal profit.
This is not the first time such activities have drawn scrutiny. In April of this year, a US Army soldier was arrested and charged with using confidential details to place bets on Polymarket. The wager concerned the specific timing of the military’s capture of Venezuelan President Nicolás Maduro, and the soldier reportedly made $410,000 in profit. Additionally, a report published in August by the Anti-Corruption Data Collective identified 152 suspicious digital wallets. These accounts had placed longshot bets on military and defense markets and collectively won $8 million.
The memo clarifies the scope of the restriction, stating it applies to all financial platforms. This includes both traditional betting services and modern prediction markets like Polymarket and Kalshi. The rule is broad, prohibiting any financial transaction that is informed by nonpublic information. Hegseth specified that the prohibition holds whether the information is formally classified or simply unclassified but not yet public knowledge.
The directive frames the issue as a matter of operational security rather than just financial ethics. By linking the behavior to the potential exploitation of data by foreign entities, the Pentagon is signaling that digital footprints in betting markets are now a vector for intelligence gathering. The memo seeks to ensure that the aggregate behavior of individual employees does not create a pattern that adversaries can decode.
Reactions to the memo have focused on the practical implications for personnel who may not realize their private knowledge constitutes insider information. The guidance serves as a clear reminder that the line between personal finance and military secrecy is becoming increasingly blurred in the digital age. For non-experts, the situation highlights how prediction markets, which function as real-time polls of public and private sentiment, can inadvertently become intelligence tools when insiders participate.
Going forward, military personnel are expected to review their financial activities to ensure compliance with the new standards. The Pentagon will likely monitor for further anomalies in betting patterns related to defense contracts or operational timelines. This move represents a significant step in adapting traditional military security protocols to the realities of contemporary digital finance and decentralized betting platforms.
The final outcome of this policy will depend on enforcement and awareness across the vast ranks of the Department of Defense. As prediction markets continue to grow in popularity and liquidity, the incentive for insiders to trade on their knowledge may persist. The memo establishes a baseline for what is acceptable, setting the stage for stricter oversight and potential disciplinary actions for those who ignore the warning.
