Context

Probability fell from 6.5% to 3.5% — a 3.0-point move over the past day.
To qualify, they must be officially recognized as active military by their sending state or organization, and their purpose must be combat—training or intelligence support does not count, but drone strikes, direct attacks on Russian forces, or missile interceptions from Ukrainian soil would. The primary resolution source is official statements from NATO, the EU, or member states, though a consensus of credible reporting may also be used. The market’s odds will react to formal acknowledgment by any NATO or EU entity of combat troop deployments. The hard deadline is Jan 1, 2027; any such acknowledgment before that date would likely shift the probability sharply higher. Conversely, absence of acknowledgment or explicit denials would keep it low. Official communiqués and credible media reports are the key inputs.
