Prediction Market Kalshi Sued Over Khamenei Trade Carveout

Prediction market Kalshi is being sued in a federal class-action lawsuit alleging it failed to adequately disclose a 'death carveout' policy related to its market predicting the removal of Iran’s Supreme Leader, Ali Khamenei. The lawsuit stems from the halting of trading and voiding of positions after Khamenei’s death, leaving winning bets unsettled. Plaintiffs argue the carveout wasn’t clearly outlined in user-facing rules, and that Kalshi’s earlier disclosures were ambiguous. Kalshi maintains it doesn’t profit from such markets and reimbursed losses, but the plaintiffs dispute the transparency of the reimbursement method, specifically the use of last-traded price and timestamps.

The dispute arises as prediction market volumes surged in 2026, increasing scrutiny on disclosure practices and risk management. The case highlights the importance of transparent rules, especially concerning sensitive events like political leadership and mortality. Kalshi’s co-founder asserts the policy is within the market rules and that no profit was made from the market.

The outcome of the lawsuit could significantly impact how prediction platforms design carveouts, communicate rules, and handle payouts in politically sensitive markets, potentially influencing the broader forecasting economy and consumer protection standards.
