Market context
Iran's airspace closure would represent a deliberate, broad suspension of commercial aviation operations across the country or a significant regional corridor, distinct from routine weather disruptions or isolated airport incidents. Such an action typically signals either military escalation, regional conflict, or a response to external threats. The resolution criteria exclude limited cancellations or delays, focusing instead on systematic shutdowns affecting transit, arrivals, and departures across Iranian airspace generally.
Historical precedent offers calibration points for assessing the 13% probability. Iran closed its airspace entirely in January 2020 following the missile strike on US bases, maintaining the closure for approximately 36 hours. More recently, partial airspace restrictions occurred during tensions in April 2024, though these fell short of the "major closure" threshold defined here. The rarity of full closures—occurring roughly once per half-decade during acute crises—suggests the baseline probability reflects genuine scarcity of triggering events rather than market mispricing.
For programmatic monitoring, traders should track escalation indicators: statements from Iran's Islamic Revolutionary Guard Corps, US military positioning updates, and announcements from aviation authorities including the Civil Aviation Organisation of Iran. Reuters and Bloomberg maintain real-time coverage of regional tensions and aviation notices. Conditional orders tied to specific geopolitical announcements (military exercises, sanctions escalation, or direct confrontations) would capture volatility spikes more efficiently than continuous manual monitoring. The market's resolution hinges on official airspace closure declarations rather than speculative reporting, making regulatory announcements the primary data source for automated triggers.
Methodology
We track Iran closes its airspace? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.
