Iran leadership change by 2026?

Platform comparison

Market context

The current real-world event centres on Mojtaba Khamenei, Iran’s 56-year-old hard-line Supreme Leader, who has held power since March 2026 following the assassination of his father, Ayatollah Ali Khamenei, in an Israeli airstrike [1][2]. Despite vowing revenge for his father’s death, Khamenei has not appeared publicly in nearly six weeks, issuing only written statements amid reports that he may be injured and his whereabouts uncertain [6]. This absence, coupled with the regime’s confrontational stance against the US and Israel, frames the market’s 0% crowd-implied probability for his removal by 2026, as no official announcement of resignation or detention has occurred [2].

Historically, supreme leader transitions in Iran have been tightly controlled by the Assembly of Experts, with Khamenei’s own succession secured by a two-thirds majority despite lacking unanimous support [3]. Comparable cases, such as the 1989 transition from Khomeini to Khamenei, show that removal typically requires internal coup, external incapacitation, or formal deposition—none of which have materialised yet [4]. The regime’s defiance, underscored by Khamenei’s low-profile background and hard-line credentials, suggests structural resilience, making abrupt leadership change unlikely before the settlement window closes [1].

Traders should monitor official announcements from Iran’s state media, scheduled addresses by the Assembly of Experts, and any developments regarding Khamenei’s health or public appearances [6]. Recent reports from CNN highlight the fear of his prolonged invisibility, while Jerusalem Post notes Khamenei’s appointment of Ali Larijani as de facto leader, sidelining the elected president [5][8]. Key dependencies include US-Israel military actions, internal IRGC dynamics, and any sudden shifts in Khamenei’s operational capacity, all of which could catalyse a “Yes” resolution if they result in his removal or incapacitation [2].

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.
