If the first new person to hold the position of Supreme Leader of Iran after Issuance is Alireza Arafi, then the market resolves to Yes.
Additional Conditions
The market resolves based on who actually assumes the office of Supreme Leader, not who is elected or nominated. Acting or interim appointments count as holding the position if they formally assume the office. The person must be different from whoever held the position at market issuance - if the same person continues in office through the expiration date, all markets resolve to No. For countries where the equivalent position has a different title (e.g., Chancellor in Germany), the specific title will be used. Resolution is based on official announcements from the country's legislature or government, with The New York Times as a secondary source for confirmation.
