Trader consensus on Polymarket prices a near-certain 99.9% implied probability against Strait of Hormuz shipping traffic returning to normal—defined as pre-crisis levels of around 140 weekly transits—by April 30, 2026, driven by the ongoing 2026 US-Iran conflict's dual blockade, with Iran restricting access amid US naval enforcement on its ports and reports of mines and shoot-to-kill rules deterring commercial vessels. Recent developments, including Iran's mid-April reopening reversal on April 18 and traffic plummeting to 5-8 daily transits, reinforce this positioning, exacerbated by Pentagon testimony on April 21 estimating six months for clearance. Tail risks include an unforeseen ceasefire or diplomatic breakthrough, though escalating hostilities diminish such prospects as the deadline arrives.

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 April 30, 2026, however, 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.
