Result Rules

NATO's Article 4 allows any member to call for consultations with allies if it believes its territorial integrity, political independence, or security to be threatened.

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.

AI Valuation Analysis: Finding Market Mispricings & EV Gaps

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Based on the latest data model run, several key contracts stand out with significant deviations:
