Khamenei Death: Prediction Market Firm Kalshi Faces Lawsuit Over $54 Million Payment Dispute
Jakarta — Web-based prediction market platform Kalshi is facing legal action over its alleged refusal to pay approximately US$54 million (Rp916 billion) to users who won bets predicting that Iran’s Supreme Leader Ayatollah Ali Khamenei would leave office by 1 March 2026.
Khamenei died as a martyr in a brutal attack by the United States and Israel in late February 2026. The escalating regional conflict caused severe disruptions across the Middle East, including flight disruptions, internet outages, damage to public facilities and critical infrastructure, and civilian casualties.
The lawsuit, filed on Thursday 5 March in the US District Court for the Central District of California, alleges that Kalshi deliberately invoked an “exception clause for death” after Khamenei’s death to avoid paying out winnings on its “Khamenei Market.”
According to the plaintiffs, the original terms of the Khamenei Market clearly included departure from office through any means, including death. Given that an armed US naval fleet had been preparing to attack Iran and Khamenei was 85 years old, bettors reasonably interpreted the market conditions as encompassing the possibility of his death.
The plaintiffs contend that Kalshi understood this interpretation when establishing the market. The language stating that Khamenei’s departure could result from any cause, including death, was unambiguous, according to the lawsuit. Kalshi’s sudden change to the market terms after Khamenei’s death constitutes fraud, the plaintiffs argue.
The lawsuit alleges that Kalshi continued trading on the market even as news of Khamenei’s death spread.
However, a Kalshi spokesperson stated that the company’s rules have not changed and were clear from the outset, as they “include every preventative measure to ensure people cannot trade based on death outcomes.”
“We even reimbursed all fees and net losses from our own pocket, totalling millions of dollars, to ensure that no one lost money on this market,” the spokesperson said.
Prediction markets have surged in popularity since the 2024 US presidential election, when their real-time probability assessments proved more accurate than traditional polling in predicting Donald Trump’s victory. These platforms offer tradeable yes-or-no contracts allowing users to wager on various real-world events, ranging from sports to politics and economics. Betting prices fluctuate between zero and 100 cents and are typically paid out when outcomes are confirmed.
