Iran leader end of 2026?

Platform comparison

Market context

The real-world event at the heart of this market is the de facto head of state holding power in Iran on 31 December 2026, a role constitutionally vested in the Supreme Leader but increasingly contested by military factions. With the current crowd-implied probability of 2% for a specific individual, traders must evaluate whether the dynastic succession to Mojtaba Khamenei, confirmed in March 2026, will withstand the deepening power struggle where the IRGC has already taken de facto control of government functions [1][4].

Historically, Iran has seen only two Supreme Leaders since 1979, with the 2026 transition marking the regime’s first dynastic succession after Ali Khamenei’s assassination [1][6]. Comparable cases of leadership transitions in authoritarian states suggest that formal appointments often fail to reflect actual power when military elites assume operational control; the IRGC’s April 2026 takeover of key state portfolios indicates that the Supreme Leader’s constitutional authority may be hollowed out by security forces [4][7].

Traders should monitor scheduled announcements from the Assembly of Experts regarding Mojtaba’s public appearances and any official decrees on military command, as well as dependencies on US-Israeli campaign outcomes that could destabilise the regime [2][8]. Recent reporting confirms the IRGC’s effective assumption of control over security portfolios, pushing President Pezeshkian into political deadlock, making the Supreme Leader’s formal title potentially irrelevant to de facto authority [4]. A conditional order strategy would trigger on any news of Mojtaba’s disappearance or the IRGC declaring a new leadership council, as these catalysts would directly invalidate the 2% probability assumption.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
