This market requires active-duty personnel from a NATO or EU nation to enter Ukraine for combat purposes and be officially acknowledged as doing so. While the rules provide clear positive and negative examples distinguishing direct combat operations from training or intelligence roles, there is potential ambiguity in verifying combat roles if deployments are covert or disputed. The resolution relies primarily on official statements from NATO, the EU, or member states, but also allows a consensus of credible reporting, leaving room for discretion if official statements are ambiguous or reports conflict.

Resolution rules

This market will resolve to "Yes" if active military personnel officially affiliated with any NATO or EU country enter Ukraine for combat-related military purposes directly pertaining to the ongoing conflict with Russia by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". For military personnel to qualify toward a "Yes" resolution, they must be 1) officially acknowledged as active military by the NATO or EU entity or member state they are affiliated with; 2) be publicly acknowledged by NATO or an EU-affiliated entity to have entered Ukraine for a combat-related military purpose directly pertaining to the ongoing conflict with Russia. For military personnel to qualify toward a "Yes" resolution they need be active duty and acknowledged as described above. Participation in a combat role is necessary for this market to resolve to "Yes" (e.g. military personnel providing training or intelligence support would not qualify toward a "Yes" resolution, however drone pilots or infantry directly attacking Russian troops, or soldiers targeting and downing missiles from Ukrainian soil would qualify toward a "Yes" resolution). The primary resolution source for this market will be official information from NATO, the EU, or member states of either entity, however a consensus of credible reporting will also be used.
