Iran leader end of 2026?

Platform comparison

Market context

Iran’s head of state on 31 December 2026 will likely not be the formal Supreme Leader, but the Islamic Revolutionary Guard Corps (IRGC), which has already assumed de facto control of key state functions after sidelining the president [1]. The market’s 7% YES probability reflects the narrow chance that Mojtaba Khamenei, appointed in March 2026 following his father’s assassination, retains effective command over the armed forces and core executive decisions by year-end [4][5].

Historically, Iran’s leadership transitions have seen real power concentrate in security networks rather than constitutional titles, as seen when the IRGC emerged as the governing power during Mojtaba’s contested succession [5]. Comparable cases show that dynastic successors in fragile wartime regimes often serve as symbolic figures while military elites exercise primary authority, making the 7% odds a plausible assessment of Mojtaba’s actual decision-making capacity [5][12].

Traders should monitor Mojtaba Khamenei’s public appearances and health updates, as independent sources have not verified his physical condition or decision-making ability [5]. The 60-day negotiating window following the Islamabad MOU will test whether succession stability holds, while any major hardliner political move or health development could trigger IRGC assertion of overt governance [5]. Recent reports confirm the IRGC now controls key state functions, with President Pezeshkian effectively sidelined [1].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
