Negotiations between the United States, Iran, and Oman over management of commercial shipping in the Strait of Hormuz remain stalled following a June 2026 memorandum of understanding that temporarily addressed passage and a ceasefire. Early August reports indicated Iran and Oman had finalized draft arrangements for new routes and joint oversight, prompting optimistic statements from U.S. officials about a possible announcement, yet Tehran’s subsequent demands for sanctions relief, compensation, and limits on U.S. naval presence have widened gaps. Washington continues to reject arrangements granting Iran effective control or fees, leading to reimposition of restrictions amid renewed incidents. Traders assign low near-term probabilities because these core disputes over sovereignty, security guarantees, and broader nuclear-related issues show no resolution, with upcoming diplomatic signals or further talks the main variables that could shift timelines.

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.
