In short
- Khalsi is suing California over a market settlement involving the former Iranian leader.
- Prediction markets decided to utilize a rule provision called a “death carveout,” which effectively settles and pays the market at the last traded price.
- The plaintiffs claim the market’s rules were not conspicuously disclosed and are seeking compensation for their position.
Popular prediction markets platform Kalshi is facing a class action lawsuit over its handling of markets following the ouster of Iranian leader Ayatollah Ali Khamenei.
The lawsuit, filed in the U.S. District Court for the Central District of California, alleges that the platform carried out a “predatory scheme to exploit retail consumers” by creating expectations that it would provide accurate predictions, but recently failed to do so. “Ali Khamenei is stepping down as supreme leader?” market.
The plaintiffs allege that upon Khameni’s death, which was confirmed by multiple media outlets on February 28, a “yes” decision was made to keep the contract in place for Khameni until March 1, ultimately resulting in a correct projection of $1 per share being paid.
Instead, the prediction market utilized the ‘death separation clause’, a regulatory provision that states that if a top leader leaves office ‘just because they are dead’, the market will ‘settle based on the last traded price’. In other words, under this provision, the exchange did not pay $1.00 for the “yes” stock as Plaintiff had expected.
“Plaintiffs and proposed class members who correctly predicted the outcome did not receive the money they were promised,” the lawsuit states. “Plaintiffs Risch and Gliksman, like thousands of other consumers who correctly predicted the outcome, received arbitrary amounts of money far below the value of their respective contracts as unilaterally determined by (Kalshi).”
As social media backlash grew on the day Khameni died on February 28, Kalshi CEO Tarek Monsour visited X to explain the company’s decision.
“We do not list markets directly related to death.” he said. “When you have a market where the potential outcome involves death, we design rules to prevent people from profiting from death. That’s what we’ve done here.”
The plaintiffs allege that “rules such as death division on which Defendants relied were not adequately disclosed when Plaintiffs or proposed class members entered into the transactions.”
“In these cases, we clearly outline the caveats in the rules and marketplace pages, but today was a good lesson learned that we can do more in terms of improving the UX and adding more ways to display the rules,” Monsour said.
As a result, the company repaid all fees and net losses, and Monsour emphasized: “The merchant did not lose any money” To the market.
The plaintiff in the case held approximately $259.84 worth of positions in the market, which ultimately generated more than $54 million in total trading volume.
We follow principles and laws.
1. Kalshi did not deviate from market rules. It was clear to them that death did not solve the market with a “yes”.
2. Kalsi’s rules prevented ‘death markets’ where traders profited directly from death. This is a good thing (+We are US based… https://t.co/gXMeQECFLz

In the suit’s request for relief, the plaintiffs and others similarly situated are seeking compensatory damages representing the full value of the “yes” payments and “punitive damages in an amount sufficient to punish the defendants and deter similar conduct in the future.”
Mansour: “We follow principles and laws” Posted in In admitting the lawsuit, it reiterated that the company did not deviate from the rules, that it blocked a market where traders could profit from people’s deaths, and that it did not make money on the market.
