Will the Iranian regime fall by June 30?

Platform comparison

Market context

The question is whether Iran’s current state structure can be overthrown, collapse, or lose effective control before 1 July. That is a much higher bar than temporary unrest or battlefield damage. Recent reporting from the Institute for the Study of War says Iran’s hardline leadership is still making negotiation offers on its own terms, while also preparing for possible protest waves and managing economic strain. That points to a system under pressure, but still functioning: the Supreme Leader’s office, the IRGC, parliament, and the security apparatus remain in place, and no mainstream reporting suggests those core institutions have been dissolved or replaced.

Past regime-change cases show that even severe military setbacks do not automatically produce collapse. Britannica’s account of the 2025-26 Iran war describes sanctions, currency weakness, protests, and heavy strikes, yet also shows the regime surviving the immediate shock through coercion and centralised control. More broadly, authoritarian systems often absorb short-term crises unless elite cohesion breaks, security forces defect, or a rival authority can credibly govern. At a 5% crowd-implied probability, the market is effectively pricing regime fall as a tail event, consistent with the lack of public signs that the state’s command chain has fractured.

Traders should watch for any confirmed splits among senior clerics, IRGC commanders, or parliament leaders, as well as sustained protest escalation that spreads beyond isolated cities. Also important are any official announcements on succession, emergency rule, mass arrests, or military defections, plus the pace of sanctions, internet shutdowns, and economic deterioration. ISW has noted both factional infighting and preparations for protest pressure, which matter because regime survival often turns less on rhetoric than on whether the security services stay unified and active through the settlement window.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
