If any NATO member country invokes Article 5 of the North Atlantic Treaty at any time between November 5, 2025 and December 31, 2026, 11:59 PM ET, this market will resolve to "Yes". Otherwise, this market will resolve to "No". The primary resolution source for this market will be official information from NATO (nato.int), however a consensus of credible media will also suffice.
Sources: Polymarket's Gamma API, its CLOB price history and its Data API, read every two minutes. Prices are each outcome's Yes price, which is the market's probability: 5¢ for Yes means the market gives it about 5%.
