Iran leader end of 2026?

Platform comparison

Market context

The real-world event driving this market is the question of who will hold de facto supreme power in Iran by the end of 2026, following the assassination of Ali Khamenei and the subsequent, fragile succession of his son Mojtaba Khamenei. With the current crowd-implied probability of only 2% that the market will resolve to a specific individual, traders are betting against the stability of the current leadership or the emergence of a new power centre. This low probability mirrors historical precedents where leadership transitions in authoritarian regimes often devolve into military takeovers or council-based rule rather than a clear, singular successor. For instance, the 2026 activation of Article 111 created a three-member interim council, and recent reports indicate the IRGC has already assumed de facto control of key state functions amid a deepening power struggle between the presidency and military leadership[2]. Such fragmentation suggests that the "head of state" may not be a single person but a collective entity or a military commander, making the 2% odds a rational reflection of this uncertainty.

Traders should monitor the public appearances and consolidation of power by Mojtaba Khamenei, who has yet to make a significant public debut since his election in March 2026[8]. The critical catalyst is whether he can secure the loyalty of the Revolutionary Guard and the Assembly of Experts, or if the regime shifts further toward the hardline military faction already reported to be running the government[6]. Additionally, the Assembly of Experts’ next scheduled sessions and any official announcements regarding the permanent leadership council will be pivotal. Recent analysis from the FDD highlights that five men are currently running Iran, with Ali Larijani acting as the de facto ruler, further complicating the definition of a single head of state[8]. If Mojtaba fails to emerge publicly or if the IRGC formalises its control, the market will likely resolve to a collective or military figure, validating the current 2% probability against a singular individual outcome.

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.
