US Troops Prohibited from Wagering on Military Operations on Polymarket

United States military personnel have been banned from placing wagers on military operations through the decentralised prediction market platform Polymarket, according to a directive from Defence Secretary Pete Hegseth.

The prohibition addresses growing scrutiny surrounding the use of event-contract exchanges to speculate on sensitive geopolitical and defence developments. Platforms such as Polymarket permit participants to buy and sell shares tied to binary outcomes of real-world events, with prices fluctuating to reflect aggregate market sentiment and probabilities.

Wagering on armed conflicts by active-duty service members introduces significant operational and ethical concerns. Access to non-public intelligence or strategic planning creates obvious risks of insider trading, while financial stakes in mission outcomes present severe conflicts of interest and potential security breaches for defence personnel.

Prediction markets have expanded rapidly in trading volume and visibility over the past year, drawing scrutiny from regulators and government officials worldwide. While proponents argue that information markets offer valuable forecasting utility, markets linked to military conflict and loss of life continue to test the legal and moral boundaries of the sector.
