This market is intended to capture the real-world duration of the war in practice, not to hinge on technicalities or isolated edge cases. Resolution will be guided by the overall state of the conflict as commonly understood, rather than strict literal interpretation of every individual event.

The market resolves to the number of whole weeks of active military conflict between the United States and Iran, measured from February 27 (February 28 local time). For simplicity, week boundaries are counted at Friday midnights, Pacific Time. Resolution dates are listed for each category.

Resolution is based on major news outlets such as CNN, Al Jazeera, AP, and Reuters, along with official statements. The conflict is considered ongoing while coordinated strikes, missile or drone attacks, or other significant combat operations continue. It ends when a ceasefire is reached that lasts for 4 continuous weeks, or US and Iran declare any other type of halt to hostilities that lasts for 4 continuous weeks.
