Trader consensus prices "No" at 85.5% for NATO invoking Article 5 before 2027, reflecting the absence of any armed attack on alliance territory amid ongoing Russia-Ukraine conflict spillover risks. Recent airspace violations by Russian aircraft over Poland, Romania, and Baltic states—up sharply in 2025—have prompted NATO intercepts but fall short of the treaty's "armed attack" threshold requiring unanimous consensus. Eastern flank reinforcements, including enhanced deployments in Poland and Baltics, bolster deterrence, while hybrid threats like sabotage remain below invocation levels. NATO Secretary General Mark Rutte affirmed in March no Article 5 discussions, prioritizing Ukraine aid without escalation. Potential shifts hinge on Ukraine ceasefire talks or Baltic incidents, but structural barriers and de-escalation signals sustain low probability.
