The Pentagon has implemented a ban on military personnel and civilian employees from using non-public information for betting on prediction markets, specifically targeting platforms like Polymarket and Kalshi. Secretary of Defense Pete Hegseth emphasized that this prohibition extends to both classified and unclassified information. He warned that adversaries could potentially infer U.S. movements, objectives, and timelines based on fluctuations in these betting markets. Violators of this directive could face administrative and disciplinary actions, and in some cases, even criminal charges.
