On March 3rd, it was reported that the prediction market Kalshi sparked controversy over the death of Iran’s Supreme Leader Ali Khamenei. Its “death clause” details resulted in minimal profits for traders betting on his removal. Traders initially believed that betting on Khamenei’s ousting before February 28th was a guaranteed win, but Kalshi emphasized that only death or other official causes of death count as a formal removal, and settlement will be based on the last trading price before the death news was confirmed. The CEO of Kalshi later apologized to users and announced refunds of related fees.
As the US and Israel launched joint airstrikes against Iran, trading volume in prediction markets surged, attracting global attention. On Polymarket’s international platform, six new users bet on Khamenei’s removal, with total transactions reaching $1.2 million. However, since Polymarket is not regulated by the US and lacks KYC and AML procedures, risks of regulatory issues and insider trading are difficult to control. Kalshi requires users to verify their identities, improving market regulation, but the “death clause” still caused dissatisfaction among users.
Analysts point out that the challenges faced by prediction markets are not only ethical debates but also balancing commercialization with compliance. Markets lacking strict KYC and AML procedures limit institutional investor participation, making normalization difficult. US Senator Chris Murphy criticized some individuals for potentially profiting from war and death, calling for legislation to ban such trading, while a White House spokesperson denied involvement by the Trump team.
This incident highlights the risks and regulatory gaps in prediction markets concerning sensitive political events, and serves as a reminder for traders to pay attention to contract details and settlement rules to avoid unexpected losses due to clause omissions.
