Market rules and resolution

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.

How to read this market

Each share pays $1 if its outcome happens. Buying Yes at 5% risks 5¢ to win 95¢. Prices move with news and order flow, and thin markets can swing on small trades, so check volume and spread before treating a number as the crowd's view. See our guides to implied probability and how markets resolve.
