Resolution update: proposed. An outcome has been proposed and is in its challenge window with the UMA optimistic oracle.

The FAA issued a nationwide ground stop for flights departing U.S. airports on November 13, 2026 (see: https://www.cnn.com/2026/11/13/us/faa-nationwide-ground-stop). This market will resolve to “Yes” if the FAA, the U.S. Department of Transportation, or their authorized representatives officially announce that this nationwide ground stop is no longer in effect between market creation and the listed date and time (inclusive of the listed minute). Otherwise, this market will resolve to “No”. A qualifying announcement must communicate that the nationwide (all-airports) ground stop is cancelled or otherwise no longer in effect, including where it is replaced by narrower ground stops or other traffic management initiatives at individual airports or regions. Announcements that the ground stop is lifted for, or does not affect, specific airports, regions, or flights while the nationwide ground stop remains in effect will not count. An announcement that the ground stop will end at a future time will not qualify until its effective time. The primary resolution source for this market will be official information from the FAA & the Department of Transportation; however, a consensus of credible reporting may also be used.
