Will the Iranian regime fall by September 30?

Platform comparison

Market context

The Islamic Republic’s current ruling structures face existential pressure following the February 28, 2026, US–Israeli military strikes that assassinated Supreme Leader Ali Khamenei and crippled core institutions[3][4]. With the crowd-implied probability of regime collapse by September 30 sitting at just 3%, the market reflects a belief that the IRGC and clerical apparatus retain enough cohesion to govern despite the leadership vacuum[1].

Historically, regime changes in authoritarian states rarely occur without the dissolution of key power nodes like the Supreme Leader’s office or the Guardian Council, yet comparable cases such as the 2011 Arab Spring show that even severe leadership loss can be offset by rapid succession planning[1][2]. Khamenei had already named four potential successors for each military and government post before his death, a move designed to prevent total command breakdown[2]. This pre-emptive stabilisation mirrors how other regimes have survived decapitation strikes, suggesting the 3% probability may underweight the system’s resilience.

Traders should monitor upcoming announcements on whether the US and Israel will proceed with plans to install Mahmoud Ahmadinejad as Iran’s leader, a strategy reportedly confirmed by the New York Times in May 2026[3]. Key dependencies include the timing of further decapitation campaigns and the economic conditions that triggered anti-regime protests in December 2025, which continue to worsen as the currency collapses and business sales decline[2]. Any shift in IRGC loyalty or public control over Kurdish-majority areas, where a new anti-regime coalition has outlined self-determination goals, could rapidly alter the settlement outlook[2].

What's the difference between match odds and outright odds?
