Kalshi Makes “Death Rule” Official After Controversial Khamenei Market
Traders thought they had a winning bet. Then someone died, and Kalshi changed how it settled the contract. Or at least, that’s how it felt to thousands of users who flooded social media after the U.S. launched military strikes on Iran last week.
Now Kalshi is making its “death rule” official.
The federally regulated prediction market exchange has formally notified the CFTC that it is adding a dedicated death settlement provision to its core rulebook, codifying exactly how a contract is settled when its subject dies before expiration.
What the New Rule Says
The amendment is straightforward in principle, but detailed in practice.
If a person who is the subject of a Kalshi contract dies before the contract expires, Kalshi may settle at the last traded price prior to the death.
If trading was already moving on rumors or reports before the death was confirmed, such as health scares or credible unverified news, Kalshi can roll back further, settling at the last price before those circumstances became known to the market.
Kalshi can also halt trading entirely if it reasonably believes the death has occurred, is imminent, or circumstances leading to the death may be occurring, with public notice required.
If no clean last-traded price exists, the exchange’s Outcome Review Committee determines a fair settlement. All decisions are final and not subject to appeal.
The Khamenei Incident That Forced the Issue
The rule did not come out of nowhere. When the U.S. struck Iran on February 28, Kalshi’s market on whether Supreme Leader Ali Khamenei would leave office spiked. The exchange invoked its existing death carveout, settling at the pre-strike price rather than paying out YES to traders expecting a clean resolution.
Many traders had never read far enough into the contract terms to know the clause existed. CEO Tarek Mansour posted repeatedly on X to clarify that the rules had not changed, acknowledged trader frustration, and announced a reimbursement plan for trades made during the period of confusion. Kalshi also placed a visible warning on the market interface once the strikes began.
The episode revealed a real problem: the death carveout existed in individual contract terms, buried where most traders never looked. Rule 6.3(e) fixes that by embedding the framework at the universal rulebook level, applying automatically across all applicable contracts.
The Regulatory Backdrop
Kalshi operates as a CFTC-regulated Designated Contract Market and self-certifies rule changes upon notification, meaning Rule 6.3(e) takes effect immediately. The CFTC can review and object after the fact, but no prior approval is required.
Timing is notable. On March 3, the CFTC submitted a formal prediction markets rulemaking plan to the White House budget office, marking the first step toward industry-wide federal rules.
Meanwhile, a group of Democratic senators led by Sen. Adam Schiff urged CFTC Chairman Michael Selig to prohibit any contract that resolves on or closely correlates to an individual’s death, citing existing commodity law prohibitions on assassination and terrorism contracts.
Kalshi’s approach stands in contrast to its unregulated rival, Polymarket. Polymarket reportedly allowed suspected insiders to profit over $1.2 million during the Iran strikes, funding wallets just hours in advance.
Kalshi, by comparison, reimbursed confused traders, codified its rules publicly, and strengthened compliance oversight through independent advisory partnerships and the appointment of a Head of Enforcement with white-collar crime experience.
What It Means for Traders
Before this week, traders had to dig through contract fine print to know a death carveout existed. Now it’s in the rulebook.
Any Kalshi contract tied to a living person — a world leader, CEO, or political figure — is governed by Rule 6.3(e) by default.
That means last-traded-price settlement is no longer a hidden footnote. Traders now know exactly how these markets resolve.
Kalshi has removed ambiguity, codified fairness, and signaled that compliance and transparency are central to its strategy.
If you trade Kalshi, the rules are clear: the game has changed, and surprises like the Khamenei spike will not catch you off guard again.
