TLDR:
- Kalshi is facing a $54 million class-action lawsuit over its refusal to pay out on the Khamenei market.
- Plaintiffs argue Kalshi’s death carveout was applied after Khamenei’s death, not before trading began.
- Kalshi claims its rules were always clear and that it reimbursed all fees and net losses to affected users.
- The lawsuit could set a major legal precedent for how prediction markets handle politically sensitive events.
Kalshi, a prominent prediction market platform, is now at the center of a federal class-action lawsuit. Plaintiffs allege the company refused to pay approximately $54 million to users.
These users had bet that Iranian Supreme Leader Ali Khamenei would leave office before March 1. Khamenei was killed in U.S.-Israeli strikes on Saturday.
The lawsuit was filed Thursday in the U.S. District Court for the Central District of California.
Plaintiffs Allege Kalshi Invoked Death Clause After the Fact
The lawsuit claims Kalshi did not apply its “death carveout” rule until after Khamenei was killed. According to plaintiffs, the company used this provision to avoid honoring payouts. They argue this move was both “deceptive” and “predatory” toward its own users.
Users say the market’s language was “clear, unambiguous and binary” from the start. The terms stated Khamenei could leave office for any reason, including death. Many bettors considered his death the most realistic outcome, given the military situation.
The lawsuit also notes that Kalshi continued accepting trades as reports of Khamenei’s death began to surface. Plaintiffs argue this further damaged users who were unaware the rules would later shift. This timing has become a central point of the legal dispute.
The complaint further states that “consumers understood that the most likely — and in many cases the only realistic — mechanism” for Khamenei leaving office was death.
It also asserts that “defendants understood this as well.” With a U.S. naval presence near Iran and conflict widely anticipated, the lawsuit argues users placed bets with that reality fully in mind.
Kalshi Disputes Claims, Says Rules Were Always Clear
Kalshi responded to the lawsuit with a firm denial of any wrongdoing. A company spokesperson stated the platform had “included every precaution to make sure people could not trade on the outcome of death.” According to Kalshi, the rules were consistent and transparent from the beginning.
The spokesperson added that Kalshi reimbursed all fees and net losses directly out of pocket. “We even reimbursed all fees and net losses out of pocket — to the tune of millions of dollars — to make sure not a single person lost money on this market,” the spokesperson said. The company maintains no customer suffered a financial loss.
Kalshi further insisted that it followed its own established guidelines throughout the process. The platform argues the death carveout was always part of its market structure. It was not, the company says, introduced after the fact.
Prediction markets have grown sharply in popularity since the 2024 U.S. presidential election. Platforms like Kalshi allow users to trade yes-or-no contracts on real-world events.
These markets accurately predicted Donald Trump’s election victory ahead of traditional polling methods. The outcome of this lawsuit may shape how such platforms handle sensitive, high-stakes markets going forward.
