“With an American naval armada amassed on Iran’s doorstep and military conflict not merely foreseeable but widely anticipated, consumers understood that the most likely — and in many cases the only realistic — mechanism by which an 85-year-old autocratic leader would ‘leave office’ was through his death,” the lawsuit states, adding:
“Defendants understood this as well.”
Plaintiffs claim the platform applied a contractual “death carveout” provision to block payouts after Khamenei’s death. The lawsuit alleges this interpretation of the rules prevented traders from receiving winnings tied to the market outcome and characterizes the conduct as deceptive and predatory.
Kalshi co-founder and CEO Tarek Mansour took to social media platform X to defend the company’s handling of the market and clarify its rules. “We stand by principle and law,” he wrote, emphasizing:
“Kalshi didn’t deviate from its market rules. They were clear that death did not resolve the market to ‘Yes’.”
“Kalshi’s rules prevented a ‘death market’, where traders directly profit from death. This is a good thing (+ we’re a US based market),” Mansour outlined the reasoning behind the clause. The executive also addressed the company’s handling of user funds, stating: “Kalshi made no money here, and even reimbursed all losses out of pocket. Not a single user walked away losing money from this market.”
In additional posts on X this week, Mansour detailed how the platform handled the disputed market and addressed trader complaints. He explained that the rules were never changed and that both the “death carveout” and the settlement method were included in the published guidelines from the outset. Mansour said the contract was settled using the last traded price before the time of death, noting that traders were paid according to that rule even though some expected the market to resolve to “Yes.”
