Iran leader end of 2026?

Platform comparison

Market context

The market asks who will hold de facto head-of-state power in Iran on 31 December 2026, following the assassination of Ali Khamenei in February 2026 and the March appointment of his son Mojtaba as the third supreme leader [2][3]. Mojtaba Khamenei now exercises the constitutional powers of the *rahbar*, including command of the armed forces, appointment of the judiciary and IRGC commander, and determination of the state’s political direction [4]. Historical precedent shows supreme leadership in Iran has remained within one family for 47 years, with only three individuals holding the office since 1979, suggesting structural continuity rather than abrupt change [2][7].

Traders should monitor Mojtaba Khamenei’s early consolidation moves: appointments to the IRGC, judiciary, and broadcasting, plus any shifts in Pezeshkian’s presidential authority or Ahmad Vahidi’s security role [1][4][9]. The 40-day mourning period and three-member interim council formed after Ali Khamenei’s death have already ended, with Mojtaba confirmed by the Assembly of Experts on 9 March 2026 [2][6]. Any internal dissent among Guard generals or regional realignments could alter the 4% YES probability, which currently implies Mojtaba will remain in power [2].

Platform mechanics diverge sharply here: Polymarket displays decimal odds (e.g. 0.04) with low fees and no KYC, while Kalshi uses implied probability percentages, requires full KYC, and charges higher fees; Betfair and Smarkets offer decimal odds with liquidity-dependent spreads and varying KYC thresholds. These structural differences affect how the 4% figure is interpreted and traded across books, even as the underlying event remains identical.
