Market context
Iran has not been running a permanently closed sky in 2026, but it has shown a clear pattern of short, security-driven restrictions when regional tensions spike. In January, Tehran briefly shut most of its airspace for several hours before reopening, while later conflict flare-ups in February and March pushed wider Middle East closures, including Iran, before traffic resumed[1][3][5][15][16]. That history matters for pricing: a 0% crowd-implied probability appears to reflect the market’s narrow definition of a *general* closure, plus the fact that previous Iranian actions have often been temporary, partial, or limited to specific corridors rather than a full nationwide shutdown[11][14][20].
For traders, the main catalysts are military escalation, official NOTAMs, and whether Iran’s Civil Aviation Organisation follows past practice of issuing time-limited restrictions and extensions. Recent reporting has also shown that closures can be announced with little warning and then widened or lifted within hours, with airlines rerouting immediately when notices appear[1][2][12]. The key comparison point versus sportsbook-style “yes/no” pricing is that there is no broad consensus signal for a sustained full closure; analyst and operational commentary instead describes partial reopenings, selective corridor restrictions, and continued overflight avoidance rather than an expectation of a complete Tehran FIR shutdown through 2026[11][20].
Methodology
We track Iran full airspace closure by 2026? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
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.
