Users of prediction markets wagered over half a billion dollars on the timing of the recent military strike on Iran by the United States and Israel. According to data from Bloomberg, a total of $529 million was traded on related contracts on the platform Polymarket.
An investigation by analytics firm Bubblemaps SA has identified suspicious trading patterns, suggesting the possibility of insider information. The firm found that six newly created accounts collectively profited by approximately $1 million after correctly betting that the U.S. would conduct a strike by February 28.
Analysts raise alarm over conflict betting
Nicolas Vaiman, CEO of Bubblemaps SA, highlighted the risks inherent in such markets. "The circulation of information involving war or conflict, combined with the anonymity offered by platforms like Polymarket, can create incentives for informed participants to act early," Vaiman stated. While the bets could reflect general market speculation, the precise timing and concentrated profits have drawn scrutiny.
This is not the first instance of unusual betting activity surrounding Iranian affairs. In January, analytics firm Polysights noted a significant spike in wagers on a contract concerning whether Iran's then-Supreme Leader, Ali Khamenei, would remain in his position by the end of March. Khamenei has since died.
Market operators defend ethical safeguards
The phenomenon of betting on geopolitical violence, including potential assassinations, has prompted ethical questions within the prediction market industry. Tarek Mansour, CEO of rival platform Kalshi, addressed these concerns directly. "We don't list markets directly tied to death," Mansour said. "When there are markets where potential outcomes involve death, we design the rules to prevent people from profiting from death."
Mansour added that Kalshi would reimburse all fees associated with such bets, a move positioning the platform on stricter ethical grounds compared to competitors.
Context and future implications
Prediction markets, which allow users to trade contracts on the outcome of future events, operate in a regulatory grey area. The massive volume traded on the Iran strike underscores their growing influence and the significant sums of capital flowing into speculative geopolitical gambling.
The findings from Bubblemaps are likely to intensify calls for greater transparency and oversight in these largely anonymous digital markets, particularly concerning events with profound human and geopolitical consequences.
