About this event

This event tracks whether the United States and Iran announce a diplomatic agreement on Strait of Hormuz traffic by October 23, 2026, and, if so, which political party wins control of the U.S. Senate in the 2026 midterm elections.

How the outcomes relate

The event consists of mutually exclusive outcomes covering the possible joint scenarios of a Hormuz agreement combined with Senate control, as well as an outcome for no agreement occurring. Exactly one outcome will resolve Yes.

How it resolves

If no qualifying diplomatic agreement between the US and Iran over Strait of Hormuz shipping traffic is announced by October 23, 2026, at 11:59 PM ET, the market resolves immediately to No Hormuz Agreement. If an agreement is announced by that deadline, resolution depends on which party wins control of the Senate in the 2026 midterms (majority of voting seats, or half plus the Vice Presidency, with tiebreakers based on President Pro Tempore).
