### Market description (verbatim from Polymarket)

> This market will resolve to “Yes” if Iran initiates a major closure of its airspace, that is not solely due to weather conditions, by the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”.
> 
> A “major closure” is defined as a broad closure, cancellation, or suspension of commercial flights transiting, arriving in, and departing from Iranian airspace or a major Iranian Airspace region. A qualifying closure must apply generally to flights across Iran or a major Iranian airspace region. Limited cancellations, delays, or other partial closures will not qualify. Limited exceptions to a broad closure, however, will not disqualify such a closure from counting (e.g. exceptions for certain flights pre-approved by the Iranian Civil Aviation Authority may be permitted). 
> 
> Any non-weather complete suspension of commercial arrivals and departures affecting at least two of the following airports will qualify: Imam Khomeini International Airport (IKA), Mehrabad Airport (THR), Mashhad International Airport (MHD), Shiraz International Airport (SYZ), or Isfahan International Airport (IFN).
> 
> Qualifying previous examples include the January 2026 total closure of Iranian airspace except to international flights with express governmental permission (https://www.reuters.com/world/middle-east/iran-shuts-airspace-most-flights-flightradar24-says-2026-01-14/) and the April 2024 closure of Iran’s western airspace (https://www.reuters.com/world/middle-east/iranian-airports-cancel-flights-until-monday-morning-2024-04-14/). Non-qualifying examples include the January 27, 2026 partial closure of Iranian airspace around the Strait of Hormuz (https://www.aa.com.tr/en/middle-east/iran-issues-airspace-notice-for-military-drills-near-strait-of-hormuz/3812508) and the January 25 - April 25, 2026 VFR (Visual Flight Rules) flights suspension which did not broadly close commercial aviation in a qualifying region (https://www.intellinews.com/iran-suspends-general-aviation-and-vfr-flights-in-new-airspace-directive-421997/).
> 
> Warnings, No-Fly-Zones, or other flight restrictions imposed by airlines or countries other than Iran will not be sufficient for a “Yes” resolution.
> 
> Airspace closures which occur solely due to weather conditions will not qualify.
> 
> The primary resolution sources for this market will be official information from Iranian aviation authorities and a consensus of credible reporting.
