PortWatch’s latest 7-day average (through Nov 1) is only ~4.4 transit calls/day versus a 2025 normal near 85; weekly totals lately are ~19–37. The last day at/above 60 was March 2, 2026. Reaching 60 needs a full reopening and AIS-visible traffic within ~7 weeks while the US blockade and Hormuz pressure continue—Polymarket’s ~10% Yes is slightly generous.

What counts as YES?
The source target date is market metadata and may differ from the actual event finish. The rules below determine the outcome.
This market will resolve to “Yes” if IMF Portwatch publishes a 7-day moving average of transit calls (“Arrivals of Ships”) for the Strait of Hormuz equal to or above 60 for any date between market creation and December 31, 2026. Otherwise, this market will resolve to “No”. Daily transit calls include container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. Ships not reported by IMF Portwatch will not be considered. This market will resolve as soon as IMF Portwatch publishes a 7-day moving average of transit calls equal to or above the specified level, or once data has been published for the final date in the specified period and no such value has been published. If no data has been published for the final date of the specified period within 14 calendar days (ET) after the end of that period, this market will resolve based on data published up to that point. Revisions to previously published data points made within this market’s timeframe will be considered. However, they will not disqualify a previously published data point from qualifying. Revisions to previously published data points after data is published for December 31, 2026, however, will not be considered. In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after the date on which such data is first released to allow for corrections. Data integrity issues refer only to clerical or other similar errors in the underlying data, and do not include cases where IMF Portwatch differs from alternative sources. The resolution source for this market will be IMF Portwatch, specifically the transit calls data published for the Strait of Hormuz at https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a1730, both in the chart and through downloadable files.

This requires IMF PortWatch's seven-day average to reach 60, not merely a reopening announcement. Available IMF-derived observations remain far below the threshold, while UKMTO documents continuing attacks and distinguishes AIS observations from US-reported facilitated traffic. An early diplomatic breakthrough could restore shipping, but operational recovery, insurance concerns and the measurement rule make YES unlikely. I could not verify an exact current primary-series value.

Reaching a 7-day IMF Portwatch average of 60 transit calls by Dec 31 would require a major de-escalation and lifting of the US blockade, which is possible via the ongoing diplomacy but not the base case.
