Polymarket faces scrutiny over Iran-related betting volume

Polymarket, a prediction market—defined as a platform for betting on future events—has recently drawn attention due to the massive financial volumes flowing through its geopolitical contracts. According to Bloomberg, a total of $529 million was traded on contracts specifically tied to the timing of a U.S. strike on Iran. This high-volume activity has raised questions about who is trading and what information they possess. For instance, an analysis conducted by the analytics firm Bubblemaps SA identified a highly specific pattern: six newly created accounts on the platform made a combined profit of $1 million. These accounts generated this profit by correctly betting that the U.S. would strike Iran by the deadline of February 28.

According to the source, this highly profitable and precise betting behavior could indicate insider trading. However, there are alternative explanations for the trading patterns, as the source notes that the bets might merely reflect broader speculation about U.S. intentions in Iran. Despite this possibility, the combination of high stakes and user privacy remains a point of contention. Nicolas Vaiman, the CEO of Bubblemaps, pointed out the structural risks inherent in these platforms. Vaiman stated that the circulation of information involving war or conflict, when coupled with the platform’s anonymity, “can create incentives for informed participants to act early.”

The scrutiny over these platforms is not limited to a single contract. In January, another analytics firm, Polysights, noted an apparent spike in bets on Polymarket regarding the likelihood that Iran’s now-deceased Supreme Leader Ali Khamenei would no longer hold his position by the end of March. This type of contract has drawn severe criticism, with observers raising concerns that such bets place a financial incentive on assassination. In response to the growing controversy surrounding these types of contracts, Tarek Mansour, the CEO of prediction market competitor Kalshi, clarified his company’s stance on the matter. Mansour stated that Kalshi does not list markets directly tied to death. He explained that when Kalshi operates markets where potential outcomes involve death, the platform specifically designs its rules to prevent people from profiting from death. To reinforce this policy, Mansour added that Kalshi would reimburse all fees from these bets.
