Catenaa, Thursday, March 05, 2026- Polymarket has removed a prediction market that allowed users to bet on whether a nuclear weapon would be detonated this year, following widespread criticism on social media and from industry analysts.
The contract, titled “Nuclear weapon detonation by…?”, had generated more than $838,000 in trading volume before it was archived.
Contracts referenced multiple timelines, including March 31, June 30 and before 2027. Hours earlier, the platform had shared odds on X indicating a 22% probability of a detonation by year’s end.
Prediction market analyst Dustin Gouker said wagering on nuclear conflict crosses ethical lines and risks damaging the sector’s credibility.
He warned that thinly traded markets could send misleading signals and create incentives for insider trading tied to sensitive geopolitical events.
The controversy comes amid mounting scrutiny of war-related contracts. Recent analysis cited unusual trading activity before US and Israeli strikes on Iran, with some accounts placing large bets that correctly anticipated military action. Blockchain analytics firm Bubblemaps reported suspected insider gains exceeding $1.2 million in related markets.
Regulatory pressure is also intensifying. The Commodity Futures Trading Commission has advanced an initial rulemaking step aimed at establishing clearer federal standards for prediction markets. Chairman Michael Selig has identified oversight of the sector as an early priority.
Polymarket’s decision underscores growing tension between open wagering on global events and calls for tighter safeguards as international restrictions expand.
