This market tracks whether a diplomatic agreement between the United States and Iran regarding traffic in the Strait of Hormuz will be announced, and which party will control the U.S. Senate following the 2026 midterm elections. Currently, Polymarket gives an 88.8% probability to the outcome of no Hormuz agreement being reached. The market resolves based on official information from the U.S. and Iranian governments, alongside credible reporting, with the Senate control determined by official election results and a consensus of reporting. Keep an eye on developments surrounding the November 4, 2026 election, as the results will be key to determining control of the Senate and ultimately resolving this market.
This market will resolve to "Hormuz Agreement; R Senate" if a Hormuz Agreement is announced by October 23, 2026, 11:59 PM ET, and the Republican Party wins control of the United States Senate in the 2026 United States midterm election. This market will resolve to "Hormuz Agreement; D Senate" if a Hormuz Agreement is announced by October 23, 2026, 11:59 PM ET, and the Democratic Party wins control of the United States Senate in the 2026 United States midterm election. This market will resolve to "No Hormuz Agreement" immediately if a Hormuz Agreement is not announced by October 23, 2026, 11:59 PM ET. Hormuz Agreement: A "Hormuz Agreement" will be considered to have occurred if a diplomatic agreement between the United States and Iran over traffic in the Strait of Hormuz is announced by October 23, 2026, 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 Hormuz Agreement component 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, the Hormuz Agreement component will remain undetermined 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, the Hormuz Agreement component will be determined 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 the Hormuz Agreement component will be official information from the governments of the United States and Iran and a consensus of credible reporting. Senate: A party wins control of the United States Senate if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the party that wins control of the chamber is the party that wins half of the voting seats and holds the Vice Presidency. If the outcome remains ambiguous after applying the above criteria, the chamber will be deemed controlled by the party with which the first selected President Pro Tempore of the Congress that convenes after the specified election is affiliated. The following rules govern the counting of seats for determining which party wins control of the chamber. All regular and special Senate elections that determine representation in the upcoming 120th Congress and are scheduled to take place in November 2026 as of October 31, 2026 are included. Runoffs for qualifying elections will determine attribution of the relevant seat, even if they take place after November 2026. Vacant seats for which no election or special election to fill the seat is scheduled to take place in November 2026 as of October 31, 2026 will be treated as held by the party affiliation of the most recent member to hold that seat. For seats contested in the specified election, seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected. For seats not contested in the specified election, seats are attributed to the party that holds the seat as of the date of the election. If a current sitting member of the U.S. Senate who is not up for election changes party affiliation or vacates their seat after the date of the election, the seat is attributed to the party under which the member was affiliated at the time of the election. Senate members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with, a party are included in that party’s count. If the caucus decisions of members of the Senate elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party. The resolution sources for the Senate component will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.
Currently, prediction market odds offer a different perspective than traditional polling data. While polls attempt to capture a snapshot of current voter intentions, this market reflects what traders believe will *actually* happen, incorporating a wider range of information and potential events. The difference between prediction market probabilities and polling averages can be significant, especially when considering factors like voter turnout and late-breaking news. It’s important to analyze both sources to get a comprehensive understanding of the race.
This market resolves around Nov 4, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the outcome will be determined by which party holds the majority of seats in the United States Senate following the November 2026 elections. The resolution will be based on official results certified by the relevant election authorities and reported by major news outlets. This market will settle based on the final composition of the Senate after the election.
Several factors could significantly impact this market. Major economic shifts, unexpected candidate announcements, significant legislative developments related to the Hormuz Agreement, or large-scale shifts in public opinion could all cause traders to reassess their predictions. Polling data releases, fundraising reports, and key endorsements will also be closely watched. Geopolitical events and any surprising developments related to the candidates involved could also lead to substantial price movements in this market.
