Iran’s Supreme Leader Khamenei assassinated by Israel, leadership change uncertain

The assassination of Iran’s Supreme Leader Ali Khamenei by Israel has injected volatility into prediction markets, with the likelihood of a leadership change in Iran by the end of 2026 now at 23% YES.

The death of Khamenei has rattled the Iran Leadership Status market. Traders are pricing in a 25% increased chance of a leadership vacuum by year-end, but uncertainty remains. Mojtaba Khamenei’s next move and the Assembly of Experts’ stance will determine direction. The odds of Reza Pahlavi entering Iran by June 30 sit at 6.5%, up from 4% a week ago, with the December 31 contract jumping to 15.5%.

For those betting on a regime fall by April 30, the market remains bearish at 0.2% YES, with a slight uptick for May 31 at 3.1%. Despite high face value trading volumes, actual USDC traded is modest, indicating limited conviction in an imminent collapse. The largest single move was a 4-point spike on the May 31 contract, suggesting some traders see a potential catalyst next month.

The assassination could mark a turning point, but the odds still reflect skepticism about rapid regime change. A YES share for Pahlavi’s return by December at 16¢ pays $1 if it resolves, a potential 6.25x return. That bet requires confidence in both a regime shake-up and Pahlavi’s re-entry plans gaining traction.

Watch for Assembly of Experts declarations and Mojtaba Khamenei’s public appearances. Any US or Israeli diplomatic moves recognizing new Iranian leadership would also shift these markets.
