Kalshi halted trading on its contract regarding Iran's Supreme Leader Ali Khamenei and formally resolved the position at 10:06 PM ET Saturday, following a chaotic settlement process triggered by reports of his death in U.S.-Israeli strikes. The market, titled "Ali Khamenei out as Supreme Leader?", accumulated over $50 million in total volume since launching on January 9, with approximately $20 million changing hands on Saturday alone before trading was paused at 2:59 PM ET.
The resolution mechanism proved contentious. Under CFTC-filed contract terms, the settlement price was recorded at 1:14 AM ET Saturday—the last traded price prior to the event—rather than resolving to a binary "Yes" payout. Kalshi CEO Tarek Mansour defended the platform's approach, stating, "We don't list markets directly tied to death." He explained that the rules were designed to prevent traders from profiting from mortality, noting that participants who entered positions after the death event would receive full refunds of their cost of entry.
However, the execution faced immediate backlash due to grammatical ambiguity in the contract documentation. While the official filing referenced the "last traded price (prior to the death)," the public market page specified "last traded price prior to confirmed reporting of death." This distinction created a window of hours between Khamenei's actual death and the public confirmation, during which trading continued and prices fluctuated significantly. The platform issued two clarifications acknowledging the discrepancy, which fueled accusations that the market functioned as a proxy for assassination.
The controversy extends beyond the mechanics of a single contract. Critics highlighted an inconsistency in Kalshi's historical handling of death-related events. In late December 2024, former President Jimmy Carter died at age 100. Kalshi subsequently settled its "Who will be at Trump's inauguration?" market to "No," effectively resolving a contract based on a death. This precedent was cited by detractors who argued the platform settles on death when it suits the outcome, but not when it generates revenue. Meanwhile, the platform's own communications on X during the Saturday morning surge stated, "BREAKING: The odds Ali Khamenei is out as Supreme Leader have surged to 68%," a post Mansour reposted. Amanda Fischer, a former SEC chief of staff at Better Markets, characterized the promotion as effectively offering a market on an assassination.
Regulatory Pressure Mounts on Prediction Markets
The settlement of the Khamenei contract arrives amidst heightened regulatory scrutiny of the prediction market industry, which generated over $44 billion in combined volume last year. Days prior to the Iran event, six Democratic senators led by Adam Schiff sent a letter to CFTC Chairman Michael Selig urging a ban on contracts that resolve on or correlate to an individual's death. The senators cited controversial contracts on other platforms tied to Venezuela and Ukraine as justification for the proposed restrictions.
In response, the Coalition for Prediction Markets, which includes Kalshi as a member, stated that "contracts involving death have no place on American exchanges" and asserted that regulated platforms already prohibit such outcomes. Mansour argued that the Khamenei market served a legitimate purpose, citing geopolitical, economic, and national security implications of Iranian leadership changes. He pointed to Venezuela's recent power transition as evidence that autocratic leaders can leave power without dying, suggesting the market provided essential data on regime stability beyond mere mortality.
The regulatory timeline is now set. The senators' letter established a March 9 deadline for the CFTC to respond to the proposed restrictions. With the Khamenei contract officially closed and the odds of the leader being out recorded at 68% before the final settlement, the industry faces a critical juncture in defining the boundaries of speculative trading on human events.
