A selection process is currently being held to choose the next Secretary-General of the United Nations, with the current term set to end on 31 December 2026. This market will resolve to the individual who is formally appointed as Secretary-General of the United Nations following the 2026 United Nations Secretary-General selection. To count for resolution, the individual must be formally appointed as Secretary-General of the United Nations following the 2026 United Nations Secretary-General selection. A recommendation by the United Nations Security Council alone will not be sufficient for resolution. Any interim or caretaker Secretary-General will not count toward the resolution of this market. If no such Secretary-General is appointed by June 30, 2027, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be official information from the United Nations; however, a consensus of credible reporting may also be used.Trader consensus on Polymarket favors IAEA Director General Rafael Grossi at 51% implied probability to become the next United Nations Secretary-General, following interactive dialogues with member states on April 21-22 where the four leading candidates—Grossi (Argentina), Rebeca Grynspan (Costa Rica), Michelle Bachelet (Chile), and Macky Sall (Senegal)—presented reform-focused visions amid calls for a more effective UN. Grossi's emphasis on execution, coordination, and credibility as nuclear watchdog chief amid global tensions has boosted his standing, while Grynspan's proactive peacemaking pitch secures second place; Bachelet's UN human rights experience and Sall's head-of-state background trail amid Latin American regional momentum. The Security Council recommendation process, influenced by veto-wielding permanent members, remains ahead before General Assembly appointment for the January 2027 term.
