Will the Iranian regime fall by June 30?

Platform comparison

Market context

The crowd is pricing a 1% chance that Iran's Islamic Republic—specifically its core institutional apparatus including the Supreme Leader's office, Guardian Council, and IRGC command structure—will be overthrown, collapse, or lose effective control over the majority of Iran's population by end of June 2026. This is a 18-month window from the market's opening, a relatively compressed timeframe for regime change in a state with deep security apparatus integration and decades of institutional entrenchment.

Historical precedent suggests the 1% consensus reflects genuine structural difficulty rather than mere pessimism. The Shah's fall in 1979 required years of escalating unrest, clerical mobilisation, and military fracture; the Soviet Union's dissolution took similar extended pressure. More recent cases—Tunisia 2011, Egypt's Mubarak ouster—involved weaker militaries or narrower elite coalitions. Iran's IRGC controls parallel state structures, internal security, and economic assets, creating redundancy that makes sudden collapse unlikely. No comparable authoritarian regime with equivalent security integration has fallen within an 18-month window in recent decades.

Catalysts traders should monitor include sustained economic deterioration (oil sanctions, currency collapse), mass protest escalation beyond the 2022–23 cycle, or visible fracture within the IRGC or clerical establishment. The 2024 presidential succession and Khamenei's age (85) create succession uncertainty, but institutional continuity typically survives such transitions. Recent reporting from Reuters and AP News documents ongoing repression of dissent rather than signs of imminent state failure. The 1% probability sits close to base-rate expectations for any regime change within 18 months; material upside would require either unprecedented internal schism or external military intervention, neither currently evidenced.

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

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.
