Will the Iranian regime fall by June 30?

Platform comparison

Market context

The Islamic Republic of Iran remains firmly in power following a US-Iran ceasefire agreement signed in mid-June, which terminated hostilities that began in late February and secured the release of maritime traffic through the Strait of Hormuz. This diplomatic breakthrough, brokered by Pakistan and formalised by Presidents Trump and Pezeshkian, has effectively paused the military pressure that previously included assassination attempts on Supreme Leader Ali Khamenei and strategies explicitly aimed at regime change[1][2].

Historically, comparable cases of regime collapse in the region, such as the 2011 Arab Spring or the 1979 Iranian Revolution, required the total dissolution of core security structures like the IRGC and the Guardian Council, a condition not met by the current status quo where clerical authority persists despite recent decapitation efforts[4]. The near-certain trader consensus on "No" for regime change by June 30 reflects this institutional continuity, with prediction markets and analyst lines diverging significantly from the more volatile sportsbook odds that occasionally speculate on sudden internal uprisings[8].

Traders should monitor the upcoming 60-day negotiation window regarding Iran's nuclear programme and the implementation of the Islamabad MoU, which mandates no new US sanctions while Iran maintains its current nuclear status quo[2]. Key catalysts include the formalisation of the joint mechanism with Oman for Strait authority and any potential flare-ups in Lebanon linked to Hezbollah's compliance with the ceasefire, as these dependencies could test the regime's de facto control over a majority of the population[1][3].

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.

Resolution & payout

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.
