Will the Iranian regime fall by June 30?

Platform comparison

Market context

The question is whether the Islamic Republic’s current system stops governing Iran before 30 June. At a 5% yes price, the market is treating outright regime collapse as a deep outsider outcome, and the consensus case is still continuity: the Supreme Leader’s office, the Guardian Council, the IRGC and the wider clerical-security state would all need to lose effective authority for a yes settlement. In practice, that means investors should think less about headline damage or leadership churn and more about whether there is any credible transfer of sovereign power.

Historically, regimes usually fall after prolonged elite fracture, mass defections, or a military split, not just air strikes or targeted killings. Even revolutions that look sudden often build over months as security services refuse orders, state payrolls break down, or rival centres of power emerge. That is why the underdog case here is not simply “pressure is high”, but “pressure has produced a governing void”. Absent evidence of that kind of breakdown, the 5% implied probability looks anchored to tail risk rather than base rates.

The near-term catalysts are signals of institutional fracture: public statements from senior clerics or IRGC figures, reports of command defections, evidence that the state can no longer collect taxes or pay salaries, and any announcement that a transitional authority is replacing existing offices. Recent coverage from The Economist and ISW has instead emphasised the durability of Iran’s security apparatus and the continuity of decision-making under Mojtaba Khamenei, even after leadership losses. The main value angle is therefore contrarian only if fresh reporting shows the chain of command slipping; otherwise, the favourite remains “No” and traders should expect regime fall to stay a low-probability, event-driven tail.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
