Will the Iranian regime fall before 2027?

Platform comparison

Market context

Polymarket’s current 10% YES price implies traders see a regime break in Iran before the end of 2026 as possible but still unlikely. The contract settles in USDC on Polygon through conditional tokens, so the market is effectively pricing whether the Islamic Republic’s core governing machinery — above all the Supreme Leader’s office, the Guardian Council and IRGC-backed clerical authority — loses de facto power or is replaced by a fundamentally different system before expiry.

That low-single-digit-to-teen probability fits the historical pattern for entrenched authoritarian states: they often absorb shocks until several pressures coincide. Recent analysis on Iran points to the usual ingredients for abrupt failure — economic strain, elite fragmentation, mass protest and security-force splits — but still argues that survival remains more likely than collapse because the system has strong repression capacity and can trade limited concessions for time[1]. In market terms, traders are not just asking whether unrest continues; they are pricing whether protests turn into defections, paralysed command chains or a successor authority with real nationwide control.

For catalysts, watch for any verified split inside the IRGC or regular military, large-scale strikes or protests that spread beyond one region, and signs that senior clerical or security figures are abandoning the existing chain of command[7]. Reporting during the 2026 Iran conflict has also highlighted external pressure and talk of regime-change planning by Israel and the United States, but those factors only matter for settlement if they translate into the regime actually ceasing to govern, not merely suffering damage or elite turnover[6]. On Polymarket, the practical read is that fresh headlines matter most when they affect credible continuity of rule, not just volatility.

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.
