This market will resolve to "Yes" if there is a military encounter between the military forces of at least two NATO member states between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A "military encounter" is defined as any incident involving the use of force, such as missile strikes, artillery fire, exchange of gunfire, or other forms of direct military engagement between the military forces of at least two NATO member states. Non-violent actions, such as warning shots, artillery fire into uninhabited areas, or missile launches that land in territorial waters or pass through airspace, will not qualify for a "Yes" resolution. Intentional ship ramming that results in significant damage to (e.g., a hole in the hull) or the sinking of a military ship by another will count toward a "Yes" resolution, however minor damage (scrapes, dents) will not. Note: For the purposes of this market, coast guard services or equivalent forces will be considered part of a country’s military only if they are officially designated as military forces under that country’s law or command structure; purely civilian or law-enforcement maritime agencies will not be considered military forces. The resolution source for this market will be a consensus of credible reporting.Trader consensus reflects a 91.1% implied probability of no clashes among NATO countries before 2027, driven by the alliance's institutional safeguards under Article 5, which prioritize collective defense against external threats, and a 75-year history without intra-alliance armed conflict. Recent transatlantic strains intensified over the past week, as President Trump threatened U.S. withdrawal from NATO after European allies including France, Italy, and Spain denied airspace and base access for operations amid the U.S.-Israel war on Iran, while Poland refused Patriot deployments to the Middle East. Despite rhetorical escalations and diplomatic rifts—such as Trump's "paper tiger" label—no military confrontations have materialized, with longstanding disputes like Greece-Turkey over Cyprus managed through dialogue. NATO Secretary General's upcoming Washington visit may ease tensions ahead of the 2027 horizon.
