Will the Iranian regime fall before 2027?

Platform comparison

Market context

Iran’s ruling system would need to lose effective control of the Supreme Leader’s office, the Guardian Council and the IRGC-backed security architecture for this market to resolve Yes; absent that kind of institutional break, protests and economic stress do not meet the settlement standard. Recent assessments still describe the state as coercively intact, with Johns Hopkins noting no signs of imminent collapse or military defections, and BTI characterising the situation as a deadlock in which dissent persists but the regime’s grip remains formidable.[1][2]

For historical framing, the market is closer to a *breaks in elite cohesion* problem than a simple unrest gauge. Several 2026 forecasts and regional analyses argue that regime change, if it happens, would more likely require cascading shocks, elite fracture and security-force splintering over many months, rather than street protests alone; one April forecast put forced regime change at 4-9% over one year, while Marubeni’s January report and ISW both stress resilience, opposition weakness and continued security loyalty.[4][6][7] That makes a 7% crowd price plausible as a tail-risk view, but still one that needs institutional evidence, not just volatility.[4][6]

Programmatically, the cleanest way to trade this market is to watch for high-signal triggers: formal succession moves, mass defections, loss of IRGC command unity, emergency constitutional announcements, or credible reporting that parallel authorities have displaced clerical institutions. The practical inputs are event-driven rather than narrative-driven, so a bot or conditional-order workflow would typically key off Reuters-style breaking news, opposition statements backed by observable control changes, and schedule risk around protests, cabinet or security appointments, and any external conflict escalations that could force elite realignment.[8][10][14]

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 Polymarket Review UK, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
