Market context
Israel’s airspace has been closed to civilian flights in the past during major regional escalations, most notably in February 2026 when joint US-Israeli strikes on Iran triggered a broad shutdown across eight Middle Eastern states, including Israel itself[2]. At that time, Flightradar24 and Cirium data confirmed widespread flight cancellations and rerouting, with roughly 24% of flights to the region halted[2]. Despite these precedents, the current crowd-implied probability of a major closure by May 2026 sits at 0%, reflecting Israel’s strong institutional commitment to maintaining civil aviation continuity even amid volatile security conditions[5].
On Polymarket, this contract trades in USDC on the Polygon network using conditional tokens, with prices anchored to real-time on-chain liquidity rather than abstract geopolitical speculation. Traders should monitor official announcements from the Israel Airports Authority, scheduled US military deployments, and Iran’s retaliation patterns, as these are the primary catalysts for airspace closures[4]. Recent reporting from Al Jazeera confirms that airspace closures have historically followed coordinated strikes and retaliatory moves, making diplomatic and military timelines critical dependencies[2].
The market’s zero probability implies confidence that no broad suspension will occur, yet historical volatility suggests traders must watch for sudden escalations. Any shift in Iran’s response posture or new US-Israeli operational plans could rapidly alter the risk landscape, even if current on-chain pricing remains flat[5].
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
