This market will resolve to "Yes" if Iran officially declares war on Israel by January 31, 2024 11:59 PM ET. Declarations of war must be clear, and explicit. The market will resolve to "No" if no such official declaration of war is made by the specified date. Note that Israel or Hamas declaring war is not considered toward this market's resolution. Further, if e.g. Hezbollah declared war, it will not satisfy a “Yes” resolution - only Iran itself declaring war will suffice.
