This market will resolve to "Yes" if the United States formally declares war on Iran through an act of Congress between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No." To qualify, Congress must pass a formal declaration of war, consistent with its constitutional authority under Article I, Section 8. Authorizations for the use of military force (AUMFs), executive orders, presidential statements, or military actions do not qualify unless accompanied by a formal declaration of war enacted by Congress and signed into law. The resolution source will be a clear consensus of credible reporting.US military operations against Iran, launched in late February 2026 alongside Israel, have operated under existing authorities without a formal congressional declaration of war. A ceasefire took effect in early April and has been extended indefinitely, with President Trump notifying Congress on May 1 that hostilities had terminated to address the War Powers Resolution deadline. Negotiations mediated by Pakistan continue over the Strait of Hormuz access, Iranian nuclear activities, sanctions relief, and de-escalation terms, though recent proposals from both sides have been rejected. Iran has used the pause to attempt reconstitution of missile and drone forces, while the United States maintains a naval blockade and regional deployments. These diplomatic and procedural developments, rather than escalation toward formal war powers, currently shape trader assessments of any official declaration timeline.
