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 May 31, 2026. If the reported value falls exactly between two brackets, this market will resolve to the higher range bracket. 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 data for the specified date has been published. If no data for the specified date has been published by June 14, 2026, 11:59 PM ET, this market will resolve based on data for the most recent date prior to May 31, 2026, for which data is available. This market will resolve based on the first publication of data for May 31, 2026. Any subsequent revisions will not be considered. 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.Trader consensus prices a 68.5% implied probability for an average of 0-10 ships transiting the Strait of Hormuz at end of May amid the ongoing US-Iran standoff, with daily counts hovering in the single to low teens—such as 12 crossings on May 12 and 17-18 on May 10-11—versus pre-crisis norms exceeding 100 vessels. Iranian restrictions requiring military coordination, coupled with a US naval blockade of Iranian ports since April 12, have sustained the restricted status for over 74 days, exacerbated by recent attacks on vessels like the CMA CGM San Antonio on May 4 and paused US escort operations (Project Freedom) on May 5. New Iranian shipping protocols announced May 7, extreme war risk insurance premiums (30x normal), and deadlocked peace talks mediated by Pakistan underpin expectations of prolonged low throughput, despite UN de-escalation calls and today's Trump-Xi summit.
