Dispatches from the trading floor suggest the question of who rules Iran after Khamenei is, for markets at least, already half-answered. Kalshi's prediction market prices one candidate at 66% to become the Islamic Republic's next Supreme Leader, with contracts settling only upon the incumbent's death — a macabre mechanism that sharpens every dollar wagered into a geopolitical wager on mortality itself.

The stakes are considerable. The Supreme Leader commands Iran's armed forces, nuclear programme, and judiciary, wielding authority that shapes oil markets, regional proxy conflicts, and the calculus of every neighbouring capital from Riyadh to Tel Aviv. With $114,000 in 24-hour volume, market consensus is not merely speculative chatter — it is capital with a thesis. Prediction markets have long tracked Mojtaba Khamenei, the incumbent's son, as the frontrunner, though no official succession mechanism exists in Iranian law.

Should clerical councils coalesce around a dark-horse cleric, or internal Revolutionary Guard factions splinter publicly, today's 66% favourite could find the odds refreshingly democratic once more.
