Iran succession stalls; seat stays empty

The Assembly of Experts was supposed to name a new Supreme Leader within days. Its headquarters was bombed, 90 million Iranians have no communications, and the leading candidate has an 18% probability on prediction markets.

Key takeaway

Iran's constitutional succession mechanism is effectively paralysed by the very military campaign it was designed to outlast, creating an unprecedented interregnum with no constitutional exit pathway.

Iran's foreign minister Abbas Araghchi told Al Jazeera that a new Supreme Leader could be named in "a day or two." As of Monday, it has not happened. Sanam Vakil of Chatham House assessed that the Assembly of Experts "may not convene until US and Israel wind down their operations" — a judgement grounded in physical fact: the Assembly's headquarters in Tehran was struck in the campaign's opening hours.

When Ayatollah Ruhollah Khomeini died on 3 June 1989, the Assembly of Experts convened and elevated Ali Khamenei to Supreme Leader within 24 hours. That succession was managed by Akbar Hashemi Rafsanjani, who controlled both the Assembly and the political machinery needed to enforce the outcome. No comparable figure exists today. The Interim Leadership Council formed under Article 111Ayatollah Alireza Arafi, President Masoud Pezeshkian, and Chief Justice Mohseni-Ejei — is a constitutional stopgap, not a succession mechanism.

The Assembly has 88 members, most of them elderly clerics scattered across Iran's provinces. Convening them requires secure transport, functioning communications, and a venue — all three compromised by active bombardment, a communications blackout that has cut 90 million Iranians from phone, internet, and SMS for more than 48 hours, and the destruction of the Assembly's own building.

Polymarket prices Mohseni-Ejei as the likeliest successor at roughly 18% — a number that reflects deep uncertainty, not a frontrunner. A meaningful share of bets is on the position being abolished entirely, which would mean dismantling velayat-e faqih — the guardianship of the Islamic jurist, the foundational doctrine on which Khomeini built the Islamic Republic in 1979. Araghchi's own admission that military units are "acting independently" of central government direction raises the harder question: whether a new Supreme Leader, once named, could command the forces fighting in his name. The Islamic Republic's succession architecture was designed for an orderly transfer of power between eras — not a selection under bombardment with the entire country cut off from communication.

Deep Analysis

In plain English

Iran's Supreme Leader is the most powerful figure in the country — above the president, controlling the military and judiciary. When a Supreme Leader dies or becomes incapacitated, a body of 88 senior clerics called the Assembly of Experts is supposed to meet immediately and choose a replacement. But their headquarters was bombed in the war's opening hours, communications across Iran have been cut for 90 million people, and the clerics themselves are scattered across a country under sustained attack. The result is a leadership vacuum at the top of a nuclear-threshold state at the exact moment when authoritative strategic decisions — escalate, negotiate, absorb — are most urgent.

Deep Analysis
Synthesis

Iran simultaneously faces a military crisis and a constitutional one, with each compounding the other: the communications blackout makes Assembly convening practically impossible, and the absence of an authoritative central decision-maker makes ceasefire negotiation structurally harder, since no interlocutor can credibly commit. A prolonged interregnum risks fracturing the IRGC along factional lines — Quds Force, Aerospace Force, Ground Forces — producing competing power centres rather than a unified successor, which would be qualitatively more dangerous than any single successor however hardline.

Root Causes

Khamenei systematically suppressed potential successors for three decades — most prominently Rafsanjani (died 2017) and Ali Larijani — to prevent a rival power centre from forming. This left the succession landscape populated by second-tier figures with limited theological or political legitimacy, which is why Polymarket's frontrunner holds only 18% — the market cannot identify a clear heir because none was permitted to emerge.

Escalation

The interregnum creates a decision-making vacuum precisely when strategic choices about escalation or ceasefire are most consequential; Revolutionary Guards hardline factions may fill that space autonomously, raising the risk of escalatory action disconnected from any central political authority — a dynamic that cannot be walked back by a successor once taken.

What could happen next?
  • Risk

    A prolonged succession vacuum enables IRGC hardline factions to take unilateral escalatory action — including strikes on Gulf oil infrastructure or Strait of Hormuz interference — without central political authorisation or the ability to stand it down.

  • Risk

    A weak or contested successor may overcompensate with aggressive external posturing to consolidate domestic legitimacy, extending the conflict well beyond the timeline US planners have modelled.

  • Precedent

    The first forced constitutional breach in the Islamic Republic's 47-year history establishes that extra-constitutional power transfers are survivable, potentially normalising them for future crises.

Causes and effects
This Event
Iran succession stalls; seat stays empty
Iran's constitutional succession process has been physically and logistically disrupted by the ongoing military campaign. The inability to name a Supreme Leader prolongs the command vacuum in which military units are operating independently of central government direction, and raises the question of whether velayat-e faqih — the Islamic Republic's foundational governing doctrine — survives the war.
Different Perspectives
Turkey (Shakarab consideration)
Turkey (Shakarab consideration)
Ankara serves as one of two Western-adjacent Iran back-channels while Turkish national Gholamreza Khani Shakarab faces imminent execution on espionage charges in Iran. President Erdogan cannot deflect the domestic political crisis that a Turkish execution would trigger, which would force suspension of the mediating role.
Germany (Bundestag gap)
Germany (Bundestag gap)
Belgium, Germany, Australia, and France committed Hormuz coalition hardware on 18 May. Germany's Bundestag authorisation for the coalition deployment remains pending, creating a constitutional gap between the commitment announced and the parliamentary mandate required to operationalise it.

The IEA's $106 May Brent projection met the market in one session on 20 May as Brent fell 5.16% on diplomatic optimism. Goldman Sachs and Morgan Stanley's two-layer premium framework holds: the kinetic component compressed; the structural insurance component tied to Lloyd's ROE remains unresolved.

Hull rates stand at 110-125% of vessel value on the secondary market; the Joint War Committee has conditioned cover reopening on written ROE from the coalition or PGSA. The Majlis rial bill makes any compliant ROE structurally impossible to draft while the PGSA's yuan portal remains its operational mechanism.

The 26-nation coalition paper requires Lloyd's to see written rules of engagement before Hormuz war-risk cover reopens. The Majlis rial bill adds a second governance incompatibility on top of the unpublished PGSA fee schedule; coalition ROE cannot mention rial without conceding Iranian sovereignty over the strait.
