**Ongoing Russian hybrid threats, including drone incursions, airspace violations, and infrastructure sabotage, continue to shape trader views on the likelihood of another NATO Article 4 invocation by late 2026.** The most recent formal request came from Estonia in September 2025 after Russian fighter jets breached its airspace, following Poland’s September 2025 activation over drone activity. As of mid-September 2026, no new invocations have occurred despite repeated incidents, such as a drone near a Ukrainian aircraft in Leipzig and probes in Romania and elsewhere. European Commission President Ursula von der Leyen’s September 16 proposal for an EU emergency security protocol modeled on Article 4 underscores the focus on hybrid risks below the Article 5 threshold, with NATO viewing it as complementary rather than competitive. Persistent but sub-threshold provocations and member caution have kept implied probabilities for near-term invocations relatively low.

This market will resolve to "Yes" if any NATO member invokes Article 4 of the North Atlantic Treaty between market creation and the specified date 11:59 PM ET. Otherwise, it will resolve to "No".
Article 4 is considered invoked as soon as a member formally requests consultations with NATO allies under Article 4, regardless of whether the request is later revoked.
For example, Poland's request for consultations on September 10, 2025, or Estonia's request on September 24, 2025 would each qualify for a "Yes" resolution.
If a member state only expresses intent to or is considering invoking Article 4, that alone does not suffice for a "Yes" resolution.
The primary resolution source for this market will be official information from NATO; authoritative statements from the requesting member government may also be used.
