Kalshi did not pay out its “Ali Khamenei out as Supreme Leader?” market as a “yes” after Khamenei’s death. The company said the contract had a death carveout: if he left office because he died, the market would be settled at the last-traded price before his death. Some traders said they understood the wording to mean that his departure from office—including by death—would count as “yes.” The dispute turns on the difference between the market’s short summary and the settlement rule Kalshi says governed it.
What happened to the Khamenei market?
The Kalshi event contract asked whether Iran’s Supreme Leader Ali Khamenei would be “out” by specified dates. WIRED reported on March 2, 2026, that trading volume across the market reached $54 million. After Khamenei’s death was confirmed, Kalshi paused the market for review and settled it using the last-traded price before his death, rather than paying holders of “yes” contracts as though the event had resolved yes.
That distinction mattered to traders who believed Khamenei was no longer supreme leader and expected a payout. But the reported market headline was not itself the whole settlement rule: Kalshi said the contract excluded death as a qualifying way to leave office.
Why did Kalshi use the last-traded price?
Kalshi said it does not allow customers to trade directly on the death of public figures. Co-founder Tarek Mansour described a death carveout in the contract: if a leader was “out” because of death, the market would settle at the last-traded price before the death, rather than resolve to yes. He said death carveouts were intended to prevent direct profiting from war, assassination, terrorism, or other violent outcomes.

Kalshi also said the carveout had been highlighted on the contract page. The company’s spokesperson Elisabeth Diana said Kalshi had “included every precaution on this market to make sure people could not trade on the outcome of death.” Those are the company’s explanations of its rules and actions, not a judicial determination that every trader received adequate notice.
Why did traders object?
Traders’ objection was that the market’s plain-language description appeared broader than the death exception Kalshi applied. A class-action complaint filed March 5, 2026, in the U.S. District Court for the Central District of California alleges that users saw this summary: “if Ali Khamenei leaves office before March 1, 2026, then the market resolves to yes.” Plaintiffs argue that users were not adequately informed that death would instead trigger settlement at the pre-death last-traded price.
Rank #2
The Washington Post reported that one trader saw what appeared to be winning indicators and a possible payout in the app before Kalshi froze the market. It also reported that Kalshi called one of its promotional posts “grammatically ambiguous” and offered to reimburse traders’ lost value. That account describes a trader’s experience and Kalshi’s response; it does not establish that the contract terms were legally changed or that the complaint’s allegations are true.
How the two interpretations differ
| Issue | Traders’ interpretation, as reported or alleged | Kalshi’s stated interpretation |
|---|---|---|
| What “out” or “leaves office” means | Departure from the leadership role before the deadline, including through death. | Departure qualifies only under the contract’s rules; death is carved out. |
| Effect of Khamenei’s death | He was no longer supreme leader, so “yes” should apply. | Death does not resolve the event to yes; settlement uses the last-traded price before death. |
| Disclosure | The complaint alleges the short summary did not adequately explain the death exception. | Kalshi said the carveout was included and highlighted on the contract page. |
The complaint’s account of the short summary is an allegation about what users were shown, not a court finding about the complete contract presentation. The available reporting establishes competing interpretations, not a final legal resolution of which interpretation should prevail.
What does the $54 million figure mean?
WIRED reported $54 million in trading volume; CBS described the amount as nearly $55 million, and the complaint also alleges approximately $54 million across contract dates. Trading volume measures activity in contracts. It is not evidence that customers collectively lost, were denied, or were owed $54 million, and it is not an adjudicated damages figure. The reviewed reporting does not establish a comprehensive count of dissatisfied or affected customers.
Has the lawsuit or regulatory dispute been resolved?
The complaint filed March 5, 2026, alleges breach and consumer deception. Those claims remain allegations unless established through the legal process; the sources cited here do not establish the lawsuit’s current disposition.
The settlement controversy also fed broader criticism of prediction markets involving death, war, and potentially insider information. A May 18, 2026 letter to the Commodity Futures Trading Commission, included in a U.S. Senate and Government Publishing Office hearing record, called for scrutiny of military-operation event contracts. The letter reflects its signatories’ position, not a final agency decision or court ruling. Amanda Fischer, policy director and COO of Better Markets, criticized the Khamenei contract as “more or less offering a proxy market on assassination.”

For anyone considering an event contract, the dispute illustrates why the headline question alone may not explain how an outcome is determined. The operative settlement rule can define exceptions, specify what happens when an event occurs through a particular cause, and set a payout method other than a full yes-or-no resolution. In this case, the central disagreement was whether the death exception was clear enough in the contract presentation—not whether Khamenei had died.
