TEHRAN — The prediction markets, those cold-eyed arbiters of probability, are whispering plainly: there is a two-in-three chance that Iran's Supreme Leader position changes hands before the dawn of 2045. Kalshi exchange, recording some $114,000 in daily wagers, has priced this transition at 66 cents on the dollar — a figure not easily dismissed. The current Supreme Leader, Ali Khamenei, assumed the mantle in 1989 and, at an advanced age, has long prompted speculation regarding succession. The stakes are extraordinary — Iran's Supreme Leader commands the armed forces, controls foreign policy, and holds authority over the nuclear programme. Market consensus holds that succession, when it arrives, will reshape regional dynamics from the Persian Gulf to the Levant, with rival factions already maneuvering. The question of who follows — a hardliner, a pragmatist, or some creature entirely novel — is the great unanswered riddle of Middle Eastern geopolitics.
