This market will resolve to "Yes" if an official agreement over tariffs, defined as a publicly announced mutual agreement, is reached between the United States and the listed country/entity between September 1, and September 30, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No”. If such an agreement is officially reached before the resolution date, this market will resolve to "Yes", regardless of if/when the agreement goes into effect. Agreements to extend tariff exemptions will qualify if announced as an individualized extension. However, tariff exemptions which are announced as part of a class of exemptions and do not reflect individual deals - such as Trump’s April 9 pause on all reciprocal tariffs other than those on China - will not qualify (see: https://www.whitehouse.gov/presidential-actions/2025/04/modifying-reciprocal-tariff-rates-to-reflect-trading-partner-retaliation-and-alignment/). Informal and unilateral announcements which do not constitute a finalized agreement will not count. Agreements that include the United States and the listed country/entity as parties, even if they also involve other countries, will qualify for resolution. The primary resolution source for this market will be a consensus of credible reporting confirming an agreement has been reached.
