Market context
Polymarket currently prices a broad Israeli airspace closure by end-May 2026 at essentially zero, with conditional YES tokens trading near worthless on Polygon. The market hinges on whether Israel initiates a major suspension affecting commercial aviation across its entirety or a region encompassing the majority of civilian airspace—a threshold that excludes temporary flight diversions or single-airport disruptions. Such an event would require either sustained military escalation forcing authorities to shut down transits, arrivals, and departures wholesale, or an extraordinary security incident deemed incompatible with civilian flight operations.
Historical precedent offers limited guidance. Israel temporarily closed Ben Gurion Airport for roughly 36 hours in May 2021 during the Gaza conflict, but this fell short of the market's definition requiring majority-airspace closure. The 2006 Lebanon war saw flight restrictions rather than full suspension. Airlines have voluntarily rerouted around Israeli airspace during periods of heightened tension, yet formal government-mandated closures affecting the entire civilian aviation system remain exceptionally rare in Israel's modern history. The 0% pricing reflects this scarcity of qualifying events.
Traders monitoring this contract should track escalation indicators: statements from Israel's Defence Ministry regarding airspace restrictions, any major conflict developments in Gaza or Lebanon, and official notices to airmen (NOTAMs) from the Civil Aviation Authority. Recent reporting from January 2025 shows continued regional tensions, though no imminent triggers for airspace-wide suspension. The settlement window extends 16 months, providing time for unforeseen geopolitical shifts, but the conditional token structure on Polygon means positions require sustained conviction given the current pricing.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
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.
