Prohibit military and civilian Department of Defense personnel from using prediction markets to bet on national security-related topics and hold violators accountable under the Uniform Code of Military Justice.

We urge you to issue a general order or regulation to prohibit all military and civilian personnel from utilizing prediction markets to place bets on any national security related topic.

Vindman led a bipartisan letter urging the Defense Department to ban military and civilian personnel from betting on national security-related events through prediction markets, with accountability under the UCMJ for violations.

Vindman said he sent Polymarket a letter demanding preservation and disclosure of records tied to bets on U.S. military actions, citing concerns that sensitive or classified information may have been used for personal profit.

This is a concrete, official investigative step on the same broader issue, but it does not show a completed prohibition on DoD personnel using prediction markets or an implemented UCMJ accountability mechanism.
