Latest news
headlines link to their publishersNo recent headlines matched this market. We only show an article when the names in the question appear in its headline, so a very local or very new market often has nothing. Showing nothing is deliberate: an unrelated story here would read like evidence about the price.
Headlines are matched on the names in “Will the US officially declare war on Iran by December 31, 2…”. Nobody checks them by hand, so one may not be relevant. They also say nothing about whether the price has already moved on this news.
How this market resolves
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.
