Iran full airspace closure by 2026?

Platform comparison

Market context

Iran’s skies can be shut quickly when security risk rises, and the market only resolves **Yes** if Tehran imposes a general closure that applies broadly to commercial traffic rather than a partial routing restriction. Recent precedents show how fast this can move: in January 2026 Iran closed most of its airspace for several hours, briefly allowing only limited flights with prior authorisation before reopening, while in late February 2026 it went further and closed airspace entirely during regional strikes, with flight-tracking data showing aircraft rerouted away from the FIR.[1][3][12][13]

For a programme-driven trader, the useful signals are NOTAMs, civil aviation statements, and live routing changes rather than headlines alone. Flight-tracking and safety platforms still describe Iran’s western FIR as restricted and eastern overflights as only partially reopened, with most operators avoiding the route and some Europe–Asia traffic going south via Egypt and Saudi Arabia or north via the Caucasus and Afghanistan.[2][16] Reuters also reported in January that Iran’s restriction initially exempted some international services to and from Iran with prior approval, which would not automatically meet a “general closure” threshold if it is limited or selective.[9]

The main catalysts are regional military escalation, Iranian threat responses, and any announcement from the Civil Aviation Organisation that widens a restriction from a sector or daylight-only regime to a blanket closure. Programmatically, a trader would monitor new NOTAM text, airport operating-hour changes, and whether commercial transits through the Tehran FIR stop across multiple carriers at once; isolated cancellations or western-sector limits would be weaker evidence than a full FIR-wide suspension.[6][16]

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
