The highly-watched Polymarket prediction market, asking "Will the Iranian regime fall by May 31?", is nearing its resolution date with a strong consensus that the Islamic Republic will remain in power. With a substantial trading volume of $35,671,810, the market currently shows the "Yes" outcome—indicating a regime collapse—at a mere 0.0015, while the "No" outcome stands at 0.9985.

This market is defined by stringent criteria: a "Yes" resolution requires the overthrow, collapse, or cessation of governance by the Islamic Republic’s current ruling regime. This means the dissolution or incapacitation of core structures such as the office of the Supreme Leader, the Guardian Council, and IRGC control under clerical authority, or a loss of de facto power over a majority of the Iranian population. Routine political events, reforms, or internal power shifts that preserve the core structures do not qualify.

Recent months have seen significant geopolitical developments affecting Iran. The country has been engaged in a conflict with the United States and Israel, which began around February 28, 2026. This period included the assassination of the former Supreme Leader Ayatollah Ali Khamenei on February 28, 2026, and other senior officials. Following this, Ayatollah Mojtaba Khamenei assumed the role of the new Supreme Leader in March, and other key figures like Mohammad Bagher Ghalibaf and Mohammad Bagher Zolghadr have taken on crucial leadership positions, indicating a reconstitution of the regime's command structures. This swift succession and organizational adaptation suggest the regime's resilience in the face of external pressure and leadership decapitation.

Internally, the Iranian authorities have intensified repression under what they term "wartime conditions." Since February 28, 2026, over 6,000 people have been arbitrarily arrested, and at least 39 political executions have been carried out. An 88-day internet shutdown, designed to suppress dissent, was largely restored on May 26, 2026, albeit with ongoing restrictions. While these actions highlight severe human rights abuses and internal unrest, they also demonstrate the regime's determined efforts to maintain control rather than signaling an imminent collapse that would meet the market's high threshold for resolution.

Expert opinions on the regime's stability are varied but lean towards its endurance. While Israel Defense Forces Chief of Staff Lt. Gen. Eyal Zamir noted on May 27, 2026, that the Iranian regime's future is "shrouded in uncertainty" and its "evil structure... has been significantly cracked," a February 2026 U.S. intelligence assessment indicated that even leadership losses would likely not achieve regime change due to institutional resilience. Ross Harrison of the Middle East Institute further emphasized that "cutting off the head of the snake would not bring down the regime". Ongoing peace talks with the U.S., despite continued military exchanges, also suggest a regime engaged in diplomacy from a perceived position of strength.

The current Polymarket odds reflect a dramatic shift in market sentiment. While a similar market on Polymarket was trading at 49.5% "Yes" for a May 31 resolution as recently as April 7, 2026, the present price of 0.0015 for "Yes" indicates that traders have almost entirely discounted the possibility of a regime change by the deadline. This implies a strong market consensus that, despite significant internal and external pressures, the Iranian regime's core structures will remain intact and in power through May 31, 2026. The high bar set by the market's resolution criteria, coupled with the regime's demonstrated capacity for succession and repression, underpins this overwhelming "No" prediction.
