Iran full airspace closure by 2026?

Platform comparison

Market context

Iran has already shown it can shut its skies quickly when regional tensions spike, but the closures recorded in 2026 were short-lived, partial, or tied to specific threat periods rather than a sustained blanket shutdown. In January, Iran briefly restricted most flights for about five hours before reopening, with only limited domestic resumption and some international movements allowed under prior authorisation.[1][10] In February and March, wider Middle East fighting triggered airspace closures across several states, yet Iran’s own actions still centred on time-limited NOTAMs and sector-based restrictions rather than an enduring full national closure.[8][14][15]

That history matters because the market only pays out on a general closure of the Tehran FIR, not a partial western-sector ban or a short notice advisory. The latest operational picture from aviation risk trackers says Iranian airspace has been partially reopened, with the eastern part of the FIR open for some overflights while western sections remain restricted, and most international carriers still avoiding the route for safety reasons.[7][20] On that reading, the current 0% implied probability reflects the absence of any standing, nationwide closure order rather than a view that disruption is impossible.

The main catalysts are any new military escalation, fresh US or Israeli strikes, or a direct civil aviation notice from Tehran widening restrictions beyond the current partial pattern.[6][8] Traders should watch for NOTAMs, FAA/Eurocontrol advisories, and airline rerouting decisions, because past closures have been announced abruptly and then extended or lifted within hours.[1][4][5] Scheduled diplomatic deadlines or renewed missile activity could matter most if they force Iran to prioritise defence over civil traffic, especially if the authorities suspend all commercial overflights instead of issuing another corridor-specific restriction.[11][20]

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
