Iran full airspace closure by 2026?

Platform comparison

Market context

Polymarket has this contract at **0% YES**, which implies the market sees no priced expectation that Iran will impose a blanket closure of the Tehran FIR before settlement. On Polymarket, traders buy and sell **conditional tokens** settled in **USDC** on **Polygon**, so any new NOTAM, civil aviation order, or broad routing ban can reprice the market quickly if it changes whether the closure is general rather than partial.

The main comparables are Iran’s recent short-lived or partial restrictions, which matter because this market only resolves on a **general** shutdown. Reuters reported that Iran shut most of its airspace for several hours on 14 January 2026, while still allowing certain international flights with prior authorisation before reopening the same day.[11] Earlier in 2026, flight-safety monitors reported that Iran’s airspace had reopened only in phases, with the western portion still closed while the eastern corridor remained available for overflights.[3][15] That pattern is important for reading a zero-priced contract: markets often distinguish between a full national closure and narrower restrictions that keep the western or eastern corridor open.

A trader should watch for three catalysts: formal Iranian NOTAMs from civil aviation authorities, regional military escalation, and airline rerouting behaviour that suggests overflights are being curtailed without a formal blanket ban. Reuters and CNBC both documented how quickly airspace restrictions can be introduced and then lifted within hours when tensions spike, affecting commercial transits across a key East-West route.[1][11] If Iran again restricts only specific corridors, or leaves authorised flights operating, that would not meet the market’s “general closure” threshold; a broad, all-commercial-flight prohibition across Tehran FIR would.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
