This market requires both the United States and Iran to announce acceptance of the same diplomatic agreement regarding shipping traffic in the Strait of Hormuz by October 31 at 11:59 PM ET. While detailed standards define what constitutes an agreement and an announcement, substantial interpretation is required to determine whether separate unilateral declarations represent a single qualifying bilateral instrument. If an announcement occurs near the deadline but remains ambiguous, a 14-day delay mechanism keeps the market open while seeking clarity from further official statements or a consensus of credible reporting. Ultimately, if ambiguity persists after two weeks, the market resolves based on the totality of information rather than strict official text, giving the decider significant latitude to interpret contradictory statements and news reports.

Market explained before close
This market measures whether the United States and Iran announce a diplomatic agreement regarding vessel or shipping traffic in the Strait of Hormuz by October 31.
How it resolves
The market resolves to Yes if both the US and Iran announce acceptance of the same official diplomatic agreement by October 31, 11:59 PM ET. The agreement must establish Iranian commitments to permit, restore, or increase traffic through the Strait of Hormuz. Declarative statements clearly confirming acceptance qualify, whether made jointly or separately; statements merely referencing ongoing negotiations or prospective deals do not qualify. Otherwise, the market resolves to No. If announcements are made but ambiguous, the market may stay open up to 14 calendar days after the last announcement for clarification before resolving on the totality of information. Resolution is determined by official information from the US and Iranian governments and a consensus of credible reporting.

Resolution rules at close
This market will resolve to “Yes” if a diplomatic agreement between the United States and Iran over traffic in the strait of Hormuz is announced by the specified date, 11:59 PM ET. A diplomatic agreement refers to an official agreement, treaty, deal, or substantially similar diplomatic instrument that establishes agreed actions, policies, obligations, or commitments between the United States and Iran. A qualifying diplomatic agreement must establish Iranian policies, obligations, or commitments aimed at permitting, restoring, or increasing vessel or shipping traffic through the Strait of Hormuz. All listed countries must announce their acceptance of the same qualifying diplomatic agreement for the Payout Condition to be met. A joint announcement will qualify, as will separate announcements from each entity of its own acceptance of an agreement which, taken together, directly indicate that all the listed countries accepted the same agreement. Separate announcements of individual policies will not qualify if the policies are not announced as part of a diplomatic agreement. Each announcement must be a declarative statement that clearly and unambiguously communicates acceptance of an agreement. Statements that reference ongoing negotiations or a prospective agreement, or that allude to or express support for an agreement without confirming acceptance of the agreement, do not qualify. A qualifying announcement need not reference the agreement by name or use specific terminology, provided it clearly communicates acceptance of an agreement. Whether announcements from the listed countries represent a diplomatic agreement and whether such an agreement qualifies will be primarily determined through the announcements themselves. Where an announcement is made by all listed countries but, based on the announcements, it remains ambiguous whether the announcements represent a qualifying diplomatic agreement between the countries, this market will remain open until either i) definitive confirmation that the announcements represent a qualifying diplomatic agreement between the listed entities is achieved through further announcements from the listed countries or a consensus of credible reporting or ii) 14 calendar days (ET) have passed after the date that the last country made their first potentially qualifying announcement. If, at the end of the fourteenth calendar day, no definitive confirmation has been achieved, this market will resolve based on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information. The resolution sources for this market will be official information from the governments of the United States and Iran and a consensus of credible reporting.
