This market will resolve according to the total number of transit calls that IMF Portwatch reports for the Bab el-Mandeb Strait for all days from August 31, 2026, through September 6, 2026, inclusive. 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 all relevant data has been published. If the relevant data is not published within 14 calendar days of the specified date, this market will resolve based on the most recent data published up to that point. 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. Only revisions to previously published data points made before all relevant data has been published will be considered. The resolution source for this market will be IMF PortWatch, specifically the “Arrivals of Ships” data published for the Bab el-Mandeb Strait at https://portwatch.imf.org/pages/6b1814d64903461b98144a6cc25eb79c.Recent Houthi attacks, including the August 24 strike on the Saudi tanker AMZAN and the August 11 fatal incident on the Tihamah, have sustained elevated war-risk premiums and prompted more dark transits, yet overall Bab el-Mandeb volumes have stabilized near 223–269 weekly crossings in mid-to-late August. Major carriers such as Maersk and MSC are gradually restoring Suez routings, with container traffic recovering faster than tankers amid a Houthi blockade targeting Saudi-linked vessels. This dynamic positions the 210-229 range as the market-implied leader, reflecting trader consensus on modest recovery tempered by persistent security risks and rerouting incentives. Upcoming data releases and any escalation in Red Sea incidents will likely drive near-term adjustments in implied probabilities.
