Will the Iranian regime fall by May 31?

Resolution Criteria

This market will resolve to "Yes" if the Islamic Republic of Iran’s current ruling regime is overthrown, collapsed, or otherwise ceases to govern by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. This requires a broad consensus of reporting indicating that core structures of the Islamic Republic (e.g. the office of the Supreme Leader, the Guardian Council, IRGC control under clerical authority) have been dissolved, incapacitated, or replaced by a fundamentally different governing system or otherwise lost de facto power over a majority of the population of Iran. This could occur via revolution, civil war, military coup, or voluntary abdication, but only qualifies if the Islamic Republic no longer exercises sovereign power. Routine political events such as elections, reforms, or leadership succession do not qualify. Internal coups or power shifts that preserve the Islamic Republic’s core structures also do not qualify. Only a clear break in continuity—such as a new provisional government, revolutionary council, or constitution replacing the Islamic Republic will qualify. Partial loss of territory or challenges from rebel or exile groups will not qualify unless the Islamic Republic no longer administers the majority of the Iranian population within Iran. The resolution source will be a consensus of credible reporting.

Prediction markets place the Iranian regime falling by 31 May 2026 as a heavily marginal outcome, with trading concentrated overwhelmingly on 'No'. The market requires the complete collapse or replacement of the Islamic Republic's core structures — including the Supreme Leader's office, the Guardian Council, and IRGC authority — not merely political reform or leadership change. Resolution is sourced from a consensus of credible reporting and carries a hard deadline of 31 May 2026.

Market structure

This is a binary market with a single outcome tracked: whether the Islamic Republic of Iran ceases to govern by 31 May 2026. Volume is overwhelmingly concentrated on 'No'. Resolution requires broad consensus reporting of a clear break in governmental continuity — a new provisional government, revolutionary council, or replacement constitution. Routine elections, internal coups preserving core structures, or partial territorial loss do not qualify. The resolution deadline is 31 May 2026 at 11:59 PM ET.

Background

The Islamic Republic of Iran, established following the 1979 revolution, is governed through a dual structure of elected institutions and unelected clerical bodies, with supreme authority vested in the Supreme Leader. The system has endured significant internal pressures over decades, including the Green Movement of 2009, sustained economic hardship linked to international sanctions, and the widespread 'Woman, Life, Freedom' protests of 2022–23, which represented the most serious domestic unrest in years. Despite these challenges, the regime's security apparatus — chiefly the Islamic Revolutionary Guard Corps — has consistently suppressed organised opposition. Regional dynamics, including Iranian proxy networks across the Middle East and ongoing tensions with the United States and Israel, add external dimensions to the question of regime stability. The death of Supreme Leader Khamenei's designated successor in waiting remains a subject of significant speculation regarding long-term succession.

Key factors

Several structural factors bear on whether regime collapse could occur within this timeframe. The cohesion and loyalty of the IRGC is central — historical precedent suggests militaries fracturing along factional lines is a prerequisite for rapid regime collapse. Economic conditions, including the severity of sanctions and currency devaluation, affect popular grievance levels and the regime's capacity to sustain patronage networks. The absence of a unified, credible opposition force — either domestic or in exile — limits the likelihood of a rapid transition of power. External pressure from the United States and Israel, including the possibility of military strikes on nuclear infrastructure, could destabilise the system but might also consolidate nationalist sentiment around the regime. Regional shifts, including the fall of Assad's government in Syria in late 2024, altered Iran's strategic depth and proxy architecture in ways whose domestic consequences remain contested. Any resolution 'Yes' requires not merely unrest but the actual dissolution of core governing structures, a bar that has not been met despite significant prior instability.
