Pentagon Memo Warns Troops Betting On Predictions Could Leak Battle Plans

The Pentagon is putting up a new wall between inside military knowledge and outside money. A memo sent this week tells service members they must not use nonpublic information to place bets on prediction markets. This applies to classified data and unclassified data alike. The rule covers all financial platforms. That includes traditional betting services and sites such as Polymarket and Kalshi. The goal is to stop leaks that could endanger troops in the field.

The warning came in a memo sent to senior Pentagon leadership and commanders of Combatant Command. It was also sent to Defense Department field activity directors. The subject line was clear: "Do Not Compromise Military Operations for Personal Financial Gain." The memo was issued on October 20 and published the following day.

The document explains why this is a security problem. Defense Secretary Pete Hegseth wrote that enemies watch movements in these markets. When a service member, intelligence professional, or civilian places a financial transaction on a military outcome, they create a signal. That signal can be gathered, correlated, and used by foreign intelligence services. They can use it to anticipate moves, targets, and timing. "The lives of our Service members often depend on the enemy not knowing what is coming," Hegseth wrote. He added that troops deserve protection, not exposure for personal gain.

The concern is based on recent events. In April, a US Army soldier was arrested and charged. He is accused of using confidential information to make $410,000 in Polymarket bets. The bets focused on the timing of the military's capture of Venezuelan President Nicolás Maduro. In August, a report from the Anti-Corruption Data Collective detailed other cases. That group found 152 suspicious wallets. These wallets placed longshot bets on military and defense markets. They won a combined $8 million.

Betting markets track politics and world events. Users trade on the odds that something will happen. These platforms have grown fast. They allow people to wager on many outcomes. Some people use them to hedge risk. Others treat them like stocks. The money can move when news breaks. The Pentagon wants to make sure no one is trading on secret knowledge.

The timeline here is short but clear. The arrest of the Army soldier came in April. The report on suspicious wallets followed in August. The memo arrived this week. It tells people to stop now. It does not punish past trades. It sets a rule for the future.

The memo does not offer an exception path for troops who want to trade. It states that no one may make a financial transaction informed by nonpublic information. It does not matter if the data is classified or unclassified. The rule is a blanket ban on using that knowledge for personal gain.

What happens next is enforcement. The memo went to the top of the chain. Commanders at all levels will get it. They will pass it to their people. The Pentagon will watch for violations. Any new leaks tied to betting sites could draw scrutiny. This is the latest step to guard operational details.
