Polymarket, a prediction market platform, has removed markets that allow users to bet on the probability of a nuclear weapon being detonated before a certain date following online backlash. The company has allowed bets on such events since at least 2023, following high-profile cases of users making large profits on suspiciously timed trades related to global conflicts, including bets related to the capture of former Venezuelan president Nicolás Maduro and the U.S.-Israel strikes on Iran. Critics have raised concerns that these marketplaces could create financial incentives for individuals in power to make certain decisions. Sen. Chris Murphy plans to introduce legislation banning bets on war and military strikes, which he believes could incentivize individuals in the Situation Room to profit from military decisions instead of focusing on national security. Other platforms like Polymarket and rival Kalshi have also faced scrutiny for allowing bets on outcomes that could be tied to death. The Commodity Futures Trading Commission (CFTC) Chairman Mike Selig recently hinted that clearer rules may be coming for the prediction-market industry.
