Will the Iranian regime fall by September 30?

Platform comparison

Market context

The real-world event in question is whether the Islamic Republic of Iran’s current ruling structure, including the Supreme Leader’s office and IRGC control, will be dissolved or lose de facto power over the majority of the population by September 30, 2026. Current crowd-implied odds on this specific contract sit at 3% for “Yes”, reflecting a market view that the regime remains resilient despite recent unrest.

Historically, similar probabilities have framed regimes that appear brittle yet endure due to unified security apparatuses and lack of cohesive opposition leadership. Iran expert Hamidreza Azizi noted that recent protests, while damaging to legitimacy, do not currently threaten the regime more than earlier waves of unrest, as the military-security establishment remains largely unified and no clear opposition leadership exists to rally around[3]. Comparable cases, such as the 2026 Iran war regime change efforts by the US and Israel, failed to dissolve core institutions despite military strikes and leadership assassinations[4].

Traders should monitor scheduled announcements from the Iranian interior ministry regarding dialogue with protesters, as well as any shifts in IRGC loyalty or Supreme Leader health updates. Recent protests initiated by shopkeepers in Tehran have spread to other cities, yet Polymarket adjusted its odds downward from 24% to 16% following these developments, indicating market caution[3]. Continued international sanctions and the risk of renewed conflict with the US or Israel remain key dependencies, though Azizi concludes these pressures are unlikely to cause fundamental system overhaul without unified opposition leadership[3].

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.
