If Ukraine has officially joined NATO as a full member state at any point by December 31, 2026, 11:59 PM ET this market will resolve to “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.Ongoing Russian opposition to Ukrainian NATO membership, combined with the requirement for unanimous Allied consent and the absence of a formal invitation, underpins trader consensus that accession will not occur before 2027. Despite NATO statements affirming an "irreversible path" and recent cooperation at the 2026 Ankara Summit, including enhanced military assistance, key members including the United States have signaled opposition during peace discussions, and Ukraine continues to face reform and interoperability gaps amid active conflict. Former Ukrainian military leaders have publicly assessed that standards remain unmet. Late developments such as a negotiated settlement altering security guarantees or sudden shifts in member positions could still influence the timeline, though current conditions show no such movement.
