Representative Eugene Vindman, a Virginia Democrat, launched a formal demand for Polymarket to turn over internal records, labeling well-timed bets on U.S. military operations as "traitorous" and "vile.".

The move follows reports of newly created accounts netting over $500,000 in profit by betting on sensitive geopolitical strikes just minutes before they were made public.

“The use of sensitive or classified information to place bets on military actions endangers and undermines national security and risks the lives of our men and women in uniform," Vindman wrote in a letter to Polymarket CEO Shayne Coplan last week, calling the alleged use of insider knowledge “immoral, dishonest, vile, and traitorous.” He urged Polymarket to preserve and disclose all relevant records so Congress can determine whether government or military personnel exploited access to nonpublic information. Newsweek reached out to Polymarket by email Sunday for comment.

Why It Matters

The scrutiny comes amid a broader wave of concern in Congress about prediction markets being used to trade on geopolitical events. Lawmakers have already raised alarms over well‑timed bets on the Iran war, including accounts that wagered on a U.S.–Iran ceasefire minutes before President Donald Trump announced it, and earlier trades that profited from predictions of U.S. strikes on Iran and the capture of Venezuelan leader Nicolás Maduro.
