What this market actually measures

This market will resolve to “Yes” if Israel initiates a major closure of its airspace by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”.

This summary shows the opening of the venue's official rules. ProbCast has not yet generated an independent plain-English interpretation for this contract — review the full rules before relying on it.

View full official resolution rules

This market will resolve to “Yes” if Israel initiates a major closure of its airspace by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A “major closure” is defined as a broad closure, cancellation, or complete suspension of commercial aviation across the entirety of Israeli civilian airspace or a region encompassing a majority of Israeli civilian airspace, including commercial flights transiting, arriving in, and departing from that airspace. A qualifying closure must apply generally to all flights across Israel or a qualifying subset of Israeli airspace. Limited cancellations, delays, temporary ground stops or isolated regional closures will not qualify. Limited exceptions to a broad closure, however, will not disqualify such a closure from counting (e.g. exceptions for certain pre-approved flights may be permitted). Warnings, No-Fly-Zones, flight suspensions, or other flight restrictions imposed by airlines or countries other than Israel will not be sufficient for a “Yes” resolution. Airspace closures which occur solely due to weather conditions will not qualify. The primary resolution source for this market will be official information from Israeli aviation authorities; however, a consensus of credible reporting may also be used.

Why the odds moved

The probability rose 5.0 percentage points over the last 24 hours (4.5% → 9.5%).

No verified catalyst has been linked to this move yet. ProbCast does not attribute moves to news without evidence connecting the timing of a specific report to the repricing.
