Kalshi Faces Class-Action Lawsuit Over Iran Supreme Leader Prediction Market

Kalshi, a prediction market platform, is facing a class-action lawsuit filed in the US District Court for the Central District of California on March 5, 2026, regarding its handling of a market tied to Iran’s Supreme Leader, Ayatollah Ali Khamenei. Traders allege that Kalshi failed to pay out the full value of winning contracts after Khamenei’s death on February 28, 2026, due to a “death carveout” provision in its rules. This provision stipulated that if the officeholder left solely due to death, the market would resolve at the last traded price, rather than a full payout.

Plaintiffs claim they are owed approximately $54 million, arguing that Khamenei’s death qualified as leaving office “for any cause” as defined in the contract. They further contend that Kalshi continued to allow trading even as reports of his death circulated and that the “death carveout” rule was not prominently disclosed. Kalshi maintains its rules were clear and designed to prevent profiting from a death-related outcome, and that it reimbursed all fees and net losses on the market.

The lawsuit arrives amidst increasing scrutiny of prediction markets, particularly those linked to politically sensitive events. The case raises questions about market design, ethics, and the potential for wagers that run against the public interest, as well as how platforms should present rules and settle contracts related to real-world crises. The outcome could significantly impact the future of prediction market regulations and practices.
