Who wins the Senate pending Hormuz Agreement before the midterms?

This event tracks whether the United States and Iran announce a diplomatic agreement concerning vessel traffic in the Strait of Hormuz by November 2, 2026, and which party wins control of the U.S. Senate in the 2026 midterm election.

How the outcomes relate

The outcomes represent mutually exclusive combined scenarios covering the occurrence of a Hormuz agreement and the resulting party control of the U.S. Senate. Exactly one outcome will resolve Yes.

How it resolves

An outcome resolves Yes if its specific combined condition is satisfied. If no qualifying diplomatic agreement between the U.S. and Iran over Strait of Hormuz traffic is announced by November 2, 2026, 11:59 PM ET, the event resolves immediately to "No Hormuz Agreement". If an agreement is announced by the deadline, resolution depends on whether Republicans or Democrats win control of the Senate in the 2026 midterms based on majority seat counts, tiebreakers involving the Vice Presidency, or the first selected President Pro Tempore.
