Iran's Supreme Leader Mojtaba Khamenei holds an 88% market share because the Assembly of Experts selected him in March 2026 following the February assassination of his father, Ayatollah Ali Khamenei, in U.S.-Israeli strikes. The Islamic Revolutionary Guard Corps and other security institutions backed the rapid succession under Article 107 of the constitution to maintain continuity amid active conflict. Iranian President Masoud Pezeshkian has repeatedly confirmed Mojtaba's health and governing capacity after extended meetings, countering injury speculation. Recent statements from the leader on hybrid threats and national cohesion, alongside foreign recognitions such as Russian congratulations, reinforce institutional acceptance. Other listed figures remain marginal due to the completed formal transition and limited near-term alternatives within the Assembly or clerical bodies.
