This market tracks whether a diplomatic agreement between the United States and Iran over traffic in the Strait of Hormuz will be announced by a specified date on Polymarket, with the leading outcome currently at 20.5% and the second outcome at 14.5%. The resolution will be based on official information from the governments of the United States and Iran and a consensus of credible reporting. Watch for any announcements or confirmations around the September 30, 2026 deadline to determine the market outcome.
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.
Currently, odds from this market suggest a 19.5% probability of a deal being reached, which aligns closely with many analyst forecasts that predict a moderate chance of progress before the deadline. While some analysts are slightly more optimistic, the market reflects a balanced view based on recent diplomatic activity and oil market tensions.

This market resolves around Oct 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Traders will watch for official announcements, signed agreements, or statements from credible diplomatic sources that confirm whether a US-Iran Hormuz deal has been reached.
Several key signals could shift this market before Oct 1, 2026. Positive diplomatic meetings, joint statements from US and Iranian officials, or signs of negotiated terms would likely increase the probability of a deal. Conversely, escalations in tensions, sanctions, or conflicting public remarks could push odds downward. Global oil market volatility and regional military activities may also influence trader sentiment. Economic indicators, such as changes in shipping rates through the Strait of Hormuz, might serve as secondary indicators. Any verifiable progress or breakdown in negotiations will be closely watched by market participants.
