Pentagon Bans Insider Wagers on Military Markets

The Department of Defense is drawing a hard line against personal profit from classified knowledge. In a directive issued this week, Defense Secretary Pete Hegseth forbids military personnel from using nonpublic information to place bets on prediction markets, warning that such activity provides a direct channel for foreign intelligence services to track American troop movements.

The prohibition, contained in a memo dated October 20, was distributed to senior Pentagon leadership, Combatant Command leaders, and Defense Department field activity directors. The directive explicitly states that personnel may not engage in any financial transaction informed by nonpublic information, whether that data is classified or unclassified. This ban extends to all financial platforms, including traditional betting services and prediction markets like Polymarket and Kalshi.

Hegseth's rationale centers on operational security. In the memo, he wrote, “Our enemies watch movements in these markets.” He explained that when a service member or civilian engages in a financial transaction regarding a military outcome, it creates a signal. That signal, he warned, can be aggregated and exploited by hostile services to anticipate movements, targets, and timing.

The directive follows a series of incidents involving military personnel and market speculation. In April, a US Army soldier was arrested and charged with using confidential information to generate $410,000 in Polymarket bets on the timing of the military’s capture of Venezuelan President Nicolás Maduro. That case highlighted how insider knowledge could be converted directly into cash.

The scope of the issue appears larger than individual cases. An August report by the Anti-Corruption Data Collective stated that the group identified 152 suspicious wallets placing longshot bets on defense markets. Those accounts won a combined total of $8 million, illustrating the significant financial incentives available to those who might trade on inside information.

With the memo now in effect, the Department of Defense is tightening its stance on insider trading. Hegseth emphasized that the lives of service members depend on the enemy not knowing what is coming. The new rules aim to prevent personal financial gain from compromising military operations or endangering the forces that carry the flag into harm's way.

The immediate next steps involve the enforcement of these regulations across all defense entities. The administration has made clear that protecting troop safety takes precedence over the financial interests of any individual service member or civilian employee.
