This market will resolve according to the 7-day moving average of transit calls (“Arrivals of Ships”) for the Strait of Hormuz that IMF Portwatch reports for the specified date. 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 the data for the specified date has been published. If no data for the specified date has been published by 11:59 PM ET on the seventh day after the end of the specified date, this market will resolve based on data for the most recent date prior to the specified date for which data is available. This market will resolve based on the first publication of data for the specified date. Any subsequent revisions will not be considered. If the reported value falls exactly between two brackets, this market will resolve to the higher range bracket. 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.Polymarket traders' skin-in-the-game consensus prices a tight race between 4-7 ships (31.5% implied probability) and 8-11 ships (28.5%) transiting the Strait of Hormuz on April 19, reflecting sustained low volumes from the Iran conflict disruptions since February 28, 2026, when daily averages plunged from 130 to 6-12 per IMF PortWatch and Windward data. Recent catalysts include a fragile US-Iran ceasefire and the US naval blockade of Iranian ports initiated April 13—enforcing compliance with six turnarounds in the first day—yet permitting limited non-Iranian traffic amid elevated war-risk insurance and AIS spoofing. Differentiating factors hinge on blockade efficacy versus sporadic upticks like 21 transits on April 12 or 17 on April 11, with oil market volatility underscoring the chokepoint's 20% global crude exposure; watch imminent negotiations for resolution swings.
