Rafael Grossi leads trader consensus at 55 percent due to his role as IAEA Director General and proven expertise navigating nuclear diplomacy amid geopolitical tensions, bolstered by Argentina’s nomination and active participation in the April 2026 UN interactive dialogues. Rebeca Grynspan follows at 29 percent, drawing support from her UNCTAD leadership and Costa Rican backing as a Latin American candidate emphasizing reform and crisis prevention. Michelle Bachelet and Macky Sall trail at under 7 percent and 9 percent respectively, constrained by Chile’s withdrawal of endorsement for Bachelet plus reported US opposition, and Sall’s lack of formal African Union backing despite his former presidency. The process, with Security Council recommendation required before General Assembly appointment for a January 2027 start, favors candidates with strong institutional credentials and minimal veto risks.
