4-bullet brief | narrative

Polymarket prices only 8% on NATO Article 5 being invoked before 2027, even as Iran strikes US bases hosting NATO-allied forces.
Attacks on US bases in Kuwait, Bahrain, and Jordan directly implicate allied-hosting nations, yet markets hold the formal collective-defense trigger at a deep discount.
Markets appear to distinguish between strikes on US-operated bases in allied territory and a formal attack on NATO member soil that would trigger Article 5.
Polymarket resolves via UMA oracle; the question requires formal Article 5 invocation, not merely allied territory incidents, which narrows the resolution trigger significantly.
