Pronóstico: Iran leader end of 2026?

Platform comparison

Market context

On 31 December 2026, the market will resolve to the individual who de facto holds supreme governing authority in Iran, including effective control over the armed forces and core executive decision-making. Polymarket prices this contract today with Mojtaba Khamenei at 84% and Reza Pahlavi at 3%, while the current crowd-implied probability for the “No Head of State” outcome sits at just 3%[1][2]. The on-chain mechanics utilise USDC on the Polygon network, where conditional tokens settle automatically once the settlement window closes at 2026-12-31T00:00:00Z[1].

Historically, Iran has experienced only two leadership transitions since 1979: from Khomeini to Ali Khamenei in 1989, and from Ali Khamenei to his son Mojtaba in March 2026 following the latter’s assassination[4]. The 2026 transition was preceded by a three-month interim period under a Provisional Leadership Council, activated via Article 111 of the constitution, which transferred powers temporarily until a permanent successor was elected by the Assembly of Experts[3][4]. This precedent suggests that even during constitutional uncertainty, real power remains concentrated within established clerical and security networks, making a complete vacuum of leadership unlikely[5].

Traders should monitor the Assembly of Experts’ scheduled meetings, any public appearances by Mojtaba Khamenei, and diplomatic signals from the U.S. regarding negotiations with Tehran’s “new leadership”[5]. Recent reports indicate that while formal selection may occur quickly, the underlying power struggle between the IRGC and clerical factions remains unresolved, with the IRGC having taken de facto control of key state functions as of April 2026[9]. A sudden announcement of a new Supreme Leader or a shift in IRGC dominance could materially alter the probability distribution before the settlement date.

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.
