Polymarket deletes 'nuclear explosion' prediction market after backlash

Decentralized prediction market Polymarket has deleted a publicly traded prediction market on a potential nuclear explosion following strong criticism from social media and market participants, The Block reported. The market was a contract on whether a nuclear explosion would occur within the year. Polymarket had previously posted on its official X account that traders were predicting a 22% chance of such an event, a post that has since been deleted. Industry observers noted that these types of markets raise ethical issues and social sensitivities, with some suggesting that prediction contracts related to war and violence have a high potential for insider trading.
