This market will resolve to "Yes" if the government of Iran officially declares war on Israel by June 20, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No." A qualifying declaration must be explicit and formal, made by the Iranian government through official channels, and must clearly state that Iran is at war. General threats, escalatory rhetoric, or announcements of military action do not qualify unless accompanied by a formal declaration of war. Only statements issued by the Iranian government qualify. The resolution source will be a clear consensus of credible reporting.
