Will the Iranian regime fall by June 30?

Platform comparison

Market context

The Islamic Republic of Iran faces its most severe internal threat since the 2022–2023 “Woman, Life, Freedom” uprising, with nationwide protests hardening into explicit demands for regime overthrow following recent explosions in Tehran. Despite this volatility, the prediction market for a regime collapse by June 30, 2026, currently implies a 0% chance of success, a stark divergence from the 14% probability now cited by trading analysts after the Tehran blasts[2]. This 0% figure also contrasts sharply with the Hudson Institute’s assessment that the regime cannot emerge from 2026 with its authority intact, even if a complete overthrow remains only one of three plausible outcomes[3].

Historically, brittle authoritarian systems like the Soviet Union in 1991 or the Shah’s Iran in 1979 demonstrate that regimes can appear stable until elite fractures and security defections trigger rapid collapse, yet the current 0% market pricing suggests traders view the IRGC’s cohesion as unbreakable despite the ongoing internal warfare within the ruling elite[5]. Unlike the 2003 Iraq invasion where external force dissolved the state, the current scenario relies on internal decay, yet the Economist notes that military strikes alone have not substantially weakened the security apparatus, leaving the regime’s dissolution uncertain[6].

Traders must monitor the succession dynamics following Supreme Leader Ali Khamenei’s death, as any diplomatic breakthrough with the US could act as a volatile catalyst for open factional war[5]. Key indicators include announcements of defections within the security services, the breakdown of centralized control, or the formal installation of a replacement leader, such as the reported US-Israel plan to install Mahmoud Ahmadinejad following Khamenei’s assassination[4]. The settlement window closes on 30 June 2026, meaning any sustained unrest fracturing the elite before this date would resolve the market to “Yes”, though current odds remain heavily skewed against this outcome[1].

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, 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.

FAQ

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.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
