Polymarket has removed a controversial market allowing bets on a nuclear weapon detonation after facing significant online criticism. The platform had previously posted a 22% probability for the event by year-end, attracting over $838,000 in trading volume. Prediction market analyst Dustin Gouker condemned such war-related betting as “grotesque,” warning it threatens the sector’s legitimacy amid growing regulatory scrutiny and allegations of insider trading on these platforms.
The crypto-based prediction platform Polymarket has archived a market that let users bet on whether a nuclear weapon would be detonated. This action followed widespread backlash after the platform posted a 22% probability for such an event by year-end.
Prediction market analyst Dustin Gouker stated “I think it’s pretty clear we shouldn’t have betting on nuclear weapons being used in a conflict.” He argued that any informational utility is outweighed by the negative optics and risk of false signals from thin trading.
This controversy unfolds as prediction markets face mounting accusations of facilitating insider trading on war and conflict outcomes. A New York Times analysis found that over 150 accounts placed four-figure bets totaling around $855,000 correctly predicting a U.S. strike on Iran just hours before it occurred.
Blockchain analytics firm Bubblemaps identified six suspected insiders who collectively netted $1.2 million on Polymarket before the conflict began. Similar allegations have surfaced around bets on geopolitical events in Venezuela and during Israel’s war with Iran.
Gouker warned these markets damage the sector’s credibility, suggesting many may see the system as “an endeavour to enrich insiders as a result.” He noted the CFTC lacks direct oversight over Polymarket‘s international site despite regulating its U.S. entity.
Regulatory attention is increasing, with the CFTC advancing formal rulemaking for prediction markets. Chairman Michael Selig has made this regulation an early priority, aiming for a single federal standard across all states.
