Iran closes its airspace by...?

Iran closes its airspace by...? is a political prediction market asking whether Iran will initiate a major closure of its airspace by the listed deadline of May 31, 2026 at 11:59 PM ET. The forecast is focused on a broad suspension or cancellation of commercial flights transiting, arriving in, or departing from Iranian airspace, or a major Iranian airspace region, and excludes disruptions caused solely by weather. To qualify, the event must involve a general closure affecting commercial aviation, with examples including major restrictions at airports such as Imam Khomeini International Airport, Mehrabad, Mashhad, Shiraz, or Isfahan. This event matters because Iranian airspace decisions can affect regional aviation, U.S. x Iran geopolitics, and broader Middle East market sentiment. Traders in the prediction market are weighing the odds based on official aviation notices and credible reporting, with current market probability near 0%, indicating a low expected outcome at present. The market’s resolution will depend on whether Iran’s aviation authorities or reliable news sources confirm a qualifying closure before the deadline.
