This is turnover across the event, not a count of independent forecasters or proof that this outcome is correctly priced. [1](https://polymarket.com/event/us-iran-hormuz-agreement-byptptpt-20260803235957575)[2](https://polymarket.com/event/us-iran-hormuz-agreement-byptptpt-20260803235957575/us-iran-hormuz-agreement-by-october-15) The Yes condition is that a diplomatic agreement between the United States and Iran over traffic in the strait of Hormuz is announced by the selected deadline, 11:59 PM ET.

Its statement separates the right of transit from whether ships and crews can safely exercise it. [3](https://www.imo.org/en/mediacentre/pressbriefings/pages/statement-on-the-ongoing-crisis-in-the-strait-of-hormuz.aspx) For operators, a route’s usability depends on physical security, insurance, port access and dependable passage. A government announcement can change expectations immediately, but commercial traffic may recover more slowly. Conversely, some ships may transit despite continuing political disagreement. Measure the variable the contract actually names. ## Which evidence would change the assessment? Sustained vessel movements or a formally adopted measure that meets the stated test would strengthen the positive case. For traffic thresholds, the correct vessel classes and observation window matter. One successful transit, a temporary military escort or a promise to reopen may not establish normal traffic. Data gaps and vessels changing identification practices can also complicate apparent counts. Check whether a new report changes the evidence for the specified condition or merely repeats an existing claim. A price move can identify a question worth investigating without establishing its cause. ## The next useful checkpoint Written-rule date: October 15; 11:59 PM (ET). The selected contract and any reporting grace period govern settlement.

A high quoted chance does not establish certainty; a low quote does not make the event impossible.
