Iran full airspace closure by August 31?
What the market is pricing
The market is pricing this outcome at roughly one-in-four odds, reflecting a low but material perceived chance of an airspace closure over the next two years. The probability fell notably in the past day, suggesting either reduced near-term tension or a downward reassessment of closure risk. The current level indicates traders see this as unlikely but not remote.
How this market resolves
This market resolves Yes if Iran initiates a general closure of its airspace—a cancellation or suspension of aviation applicable to all commercial flights—between market creation and August 31, 2026, 11:59 PM ET, and the closure is not solely due to weather conditions. It resolves No otherwise.

What could move it
- Official Iranian government action or international incident that would directly trigger or prevent an airspace closure would settle the question.
- The distinction between general closure and weather-related suspension could affect resolution interpretation; any ambiguous closure might require clarification from the market operator.
- With over two years remaining until the August 2026 deadline, significant geopolitical shifts could move odds substantially in either direction.
