US-Iran Hormuz Agreement by...?
August 31

Understand this market
This market asks whether the US and Iran will sign a real, formal diplomatic deal about keeping the Strait of Hormuz open to ships. The Strait of Hormuz is a narrow waterway between Iran and Oman, and roughly 20% of the world's oil passes through it, so who controls access there matters enormously. A Yes means both governments officially commit to an agreement that keeps shipping moving through the strait. A No means no such deal is formally announced by the deadline.
To resolve Yes, both the US and Iran must each make a clear, official announcement that they have accepted the same agreement about Hormuz shipping, with no ambiguity. The deadline is 11:59 PM ET on the date listed for each option: August 15 or August 31, 2026. One important edge case: if one side says a deal exists but the other is vague or silent, that does not qualify. Separate policy announcements that are not explicitly linked to a shared agreement also do not count. The bar for what qualifies is deliberately high.
The news from August 4, 2026, paints a tense and uncertain picture. Iran and Oman were reportedly discussing a limited single shipping corridor through the strait, a partial and temporary arrangement rather than a full deal. At the same time, the US and Iran appeared to be giving conflicting accounts of where talks stood, with Trump suggesting a quick resolution while Iran's position seemed more cautious. A drone attack on a US base in Kuwait also occurred the same day, adding friction to already complicated negotiations.
The core difficulty here is that diplomacy between the US and Iran is historically fragile, and the news from early August shows both sides telling different stories about the same talks. A ship was struck in the strait the same day negotiations were being discussed, which shows how quickly the situation can deteriorate. The resolution criteria also add their own uncertainty: even if something is announced, it must be unambiguous and formally accepted by both sides. The two deadlines are priced differently, at 27% and 36%, reflecting how much the extra two weeks matter in fast-moving diplomacy.

Resolution Criteria
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.
