Austria's April 2 announcement banning U.S. military overflights tied to the Iran war marked the latest in a series of restrictions by EU nations including Spain on March 30 and Italy denying Sigonella Air Base access, reflecting neutrality stances and de-escalation concerns amid NATO rifts. With no additional EU countries—such as Germany or France beyond case-by-case reviews—imposing new barriers in the two weeks since, trader consensus implies an 86.5% probability against further action by April 30. U.S. diplomatic pressure, including President Trump's criticisms, and emerging Iran ceasefire talks around April 10 have cooled momentum, while ongoing Strait of Hormuz tensions have not prompted broader airspace denials. Late escalations or renewed U.S. requests could still shift dynamics.

Austria announced this month that U.S. military planes involved in Operation Epic Fury could not use its airspace, joining other EU countries in restricting U.S. military aircraft operations (see: https://thehill.com/policy/international/5815053-austria-defies-trump-war/).
This market will resolve to “Yes” if any EU member state that has not yet applied such a restriction officially announces that U.S. military aircraft are not permitted to use its airspace or land in its territory, or announces that U.S. military aircraft are generally not allowed to use certain military bases or airports within its jurisdiction, by April 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.
A restriction applying only to a subset of U.S. military aircraft (e.g. only aircraft involved in Operation Epic Fury) will qualify.
A qualifying restriction must be a standing policy; isolated instances of access denial will not count. For example: Italy’s isolated refusal to allow U.S. military aircraft to use Sigonella airbase (see: https://www.reuters.com/business/aerospace-defense/italy-refuses-us-aircraft-use-sicily-base-middle-east-operations-source-says-2026-03-31/) would not count.
An overwhelming consensus of credible reporting that another EU country has implemented a qualifying restriction on U.S. military aircraft will also suffice for a “Yes” resolution. Mere statements from U.S. officials, however, will not qualify.
The primary resolution source for this market will be official information from the relevant countries; however, a consensus of credible reporting may also be used.
