Will NATO expand by March 31?

This is a market on whether the North Atlantic Treaty Organization (NATO) will have more than 30 full member states for any length of time before March 31, 2023, 11:59:59 PM ET. If NATO has more than 30 member states at any point by March 31, 2023, this market will resolve as “Yes”. Otherwise, this market will resolve to "No." The primary settlement source for this market will be the official NATO website (https://www.nato.int/cps/en/natohq/nato_countries.htm), however other credible sources may be used.
