Will the Iranian regime fall by September 30?

Platform comparison

Market context

Iran’s regime would have to lose the office of the Supreme Leader, the clerical institutions around it, and effective coercive control for this market to resolve “Yes”, so the key question is not unrest but state continuity. That is why the current 2% crowd-implied probability looks closer to a tail-risk trade than a baseline expectation, and it sits well below the 7% “yes” price on Polymarket’s broader year-end 2026 contract, suggesting this shorter-dated contract is being priced even more sceptically.[19]

Recent comparable cases show why traders usually discount abrupt regime collapse in Iran: the Islamic Republic has repeatedly absorbed sanctions, protest waves, and external pressure without a clean institutional break, and analysts still describe its security apparatus as intact despite severe strain. Brookings and other recent assessments argue there are no clear signs of imminent collapse, while a 2026 forecast by a policy research group put one-year regime-change odds in the low single digits and said the most likely outcome remains survival in weakened form rather than the dissolution of the system.[2][4][13]

For catalysts, traders should watch any confirmation of elite defections, a prolonged breakdown in succession management, or signs that the IRGC is losing cohesion, because those are the kinds of developments that would move this market sharply. Reuters-linked reporting cited in current coverage points to an interim leadership council after Khamenei’s death, which supports continuity rather than rupture, and recent reporting on ceasefire diplomacy and reopening the Strait of Hormuz also points to functional state capacity rather than imminent collapse.[1][19] Opinion research and institute reports this year also flag economic exhaustion, protest risk, and external pressure as relevant, but most stop short of treating them as sufficient on their own to topple the regime by September 2026.[5][12][16]

Methodology

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

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
