Polymarket removed a prediction market tied to the fate of a missing U.S. service member after widespread backlash, saying the listing breached its “integrity standards.” The controversy centered on a market asking whether U.S. authorities would confirm the rescue of a pilot reportedly shot down over Iran; more than 60% of bettors had wagered that a rescue would not be confirmed by Saturday.
Representative Seth Moulton condemned the market as “disgusting,” expressing alarm that people were speculating on the possible fate of an injured service member. In response to the criticism, Polymarket said it took the market down immediately, acknowledged it should not have been listed and said it is reviewing how the market passed internal safeguards. The company did not specify which rule or provision had been violated.
Users and journalists pressed Polymarket for clarity. Jack Newsham of Business Insider noted that Polymarket’s publicly posted Market Integrity page and terms of service did not make it clear which prohibition applied in this case.
The episode comes as Polymarket has been expanding monetization: after a fee model change on March 30, daily fees reportedly rose from roughly $363,000 to more than $1 million, with peak revenue approaching $1 million. The platform’s fee increases cover categories including finance, politics and technology.
Separately, prediction markets have faced scrutiny over possible insider trading. Reports last month said a group of traders earned about $1 million by accurately betting on the timing of U.S. strikes on Iran, with some trades placed only hours before the attacks—activity that drew suspicions because of patterns in newly created wallets concentrated on strike-related bets. In light of such concerns, at least 42 Democratic lawmakers have urged the U.S. Commodity Futures Trading Commission and the Office of Government Ethics to warn federal employees not to use non-public information when trading on prediction markets.
