This market will resolve to "Yes" if an official agreement over Iranian nuclear research and/or nuclear weapon development, defined as a publicly announced mutual agreement, is reached between the United States and Iran by June 30, 2026, 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 that include the United States and Iran as parties, even if they also involve other countries (e.g., a multilateral deal like the JCPOA), will qualify for resolution. The primary resolution source for this market will be an official announcement by the United States and/or the Islamic Republic of Iran, however an overwhelming consensus of credible reporting confirming an agreement has been reached will also qualify.
