TEHRAN — The crystal ball, it seems, goes dark at the borders of the Islamic Republic. Prediction markets on Kalshi price the leading contender for Iran's next Supreme Leader at a mere 15 percent, a figure that speaks less to any candidate's strength than to the fog of uncertainty surrounding the most opaque succession in modern geopolitics.

The Supreme Leader holds absolute authority over Iran's military, judiciary, and foreign policy — a throne of enormous consequence with no transparent line of succession. Ayatollah Khamenei, now in his eighties, has offered no public heir apparent, and the Assembly of Experts, the clerical body empowered to choose his replacement, conducts its deliberations far from prying eyes. With $114,025 in daily trading volume, Kalshi's market consensus suggests punters are spreading their bets thin — a rational response to a fundamentally unknowable contest.

A surprise health crisis, a factional rupture within the clerical establishment, or a dramatic geopolitical shift could rapidly concentrate market probability around a single name.
