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.Ongoing US-Iran hostilities since February 2026 airstrikes have centered on the Strait of Hormuz, nuclear negotiations, and regional proxies, yet Congress has not authorized a formal declaration of war under constitutional authority. The June 2026 memorandum of understanding expired in mid-August without a comprehensive agreement, prompting renewed Iranian shipping restrictions, US naval responses, and a pivot by the Trump administration to intensified sanctions and economic measures rather than expanded military authorization. Recent statements from President Trump describing the situation as a limited “detour” and Iranian officials labeling sanctions a broader “declaration of war” reflect continued brinkmanship without triggering formal war powers processes. Trader sentiment remains shaped by the absence of congressional action, preference for economic pressure, and lack of imminent escalation thresholds.
