Polymarket shuts down nuclear detonation prediction market after backlash
Prediction betting platform Polymarket has deactivated a controversial market that allowed users to wager on the possibility of a nuclear weapon detonation. The decision came after a wave of public criticism amid rising tensions between the United States and Iran.
The contract allowed traders to speculate on whether nuclear weapons would be used this year. Before it was removed, the market estimated the probability of such an event at around 22% by the end of the year, drawing additional attention from media and analysts. Coingape first reported the development.
The market, titled “Nuclear weapon detonation by…?”, attracted significant trading activity and generated more than $838,000 in volume. Participants could place bets on different timeframes, including March 31, June 30, or even sometime before 2027.
Despite the high level of activity, many experts criticized the market as inappropriate. According to them, using the possibility of a nuclear attack as a speculative trading instrument crosses ethical boundaries.
Ethical and security concerns
Prediction market analyst Dustin Gouker said betting on the use of nuclear weapons should not exist. He argued that any potential value from estimating the probability of such an event does not outweigh the moral concerns and negative societal impact.Experts have also warned about possible security risks. If insider information appears on similar markets, contract prices could begin to move before official announcements, creating opportunities for manipulation.
Growing pressure on prediction markets
The controversy surrounding Polymarket is part of a broader debate about the regulation of prediction platforms. Services such as Polymarket and Kalshi have recently faced increasing criticism over contracts tied to sports, politics, and global crises.Some experts and policymakers are already calling for stricter regulation of such platforms. They argue that betting on events related to war, death, or disasters should not be part of commercial prediction markets.
Earlier, we reported that Polymarket hosts wagers on events that often appear improbable, premature, or controversial. Yet users still place bets on them—sometimes worth millions of dollars.
