Mojtaba Khamenei holds an overwhelming 87.8% market share because he was formally selected by Iran's Assembly of Experts in March 2026 to succeed his father, the late Ayatollah Ali Khamenei, following the latter's death in late-February strikes. Official affirmations from President Masoud Pezeshkian, including multiple meetings and recent statements on his health and continued guidance, combined with IRGC allegiance and a congratulatory message from Russian President Putin in early October, reinforce perceptions of institutional continuity. Traders appear to view these factors as outweighing unverified reports of physical limitations or post-conflict transition planning, positioning Mojtaba as the consensus outcome through the end of 2026 absent a verified change in the Assembly's stance or major escalation.
