Will the Iranian regime fall by June 30?

Platform comparison

Market context

The Islamic Republic of Iran has just secured a fourteen-point Memorandum of Understanding with the United States, formally ending the six-week war that began in late February and lifting the US naval blockade on its ports[1]. This breakthrough, brokered by Pakistan and signed by Presidents Trump and Pezeshkian on 17 June, stabilises the regime’s core structures, including the office of the Supreme Leader and IRGC command, rather than dismantling them[1]. Consequently, the crowd-implied probability of the regime collapsing by June 2026 remains at zero, as the state has successfully pivoted from active conflict to diplomatic consolidation[1].

Historically, comparable cases such as the 1979 Iranian Revolution or the 2011 Arab Spring show that regime collapse typically follows sustained internal paralysis or total loss of de facto power over the majority of the population[3]. In contrast, the current leadership under Mojtaba Khamenei has rallied key figures like Ahmad Vahidi and Masoud Pezeshkian to his side, demonstrating resilience rather than the paralysis that plagued the state in late March[3]. The recent ceasefire and subsequent MOU have reversed the earlier narrative of a "paralyzed" decision-making process, suggesting the regime is reconstituting its military capabilities and sovereignty over the Strait of Hormuz[2].

Traders should monitor the implementation of the MOU’s immediate deliverables, specifically the toll-free access to the Strait of Hormuz for the next two months and the lifting of sanctions[1]. Any failure in these deliverables or a resurgence of hostilities in Lebanon could destabilise the fragile peace, though current reports indicate the deal is complete and hostilities have terminated permanently[1]. Analysts at the Institute for the Study of War note that while economic relief could support military reconstitution, the regime remains focused on consolidating sovereignty rather than facing internal dissolution[2]. The next critical schedule dependency is the follow-on negotiation regarding Iran’s fissile stockpiles, which will test the durability of this new status quo[1].
