This market will resolve according to the 7-day moving average of transit calls (“Arrivals of Ships”) for the Bab el-Mandeb Strait that IMF Portwatch reports for September 30, 2026. 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 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. The resolution source for this market will be IMF Portwatch, specifically the transit calls data published for the Bab El-Mandeb Strait at https://portwatch.imf.org/pages/6b1814d64903461b98144a6cc25eb79c, both in the chart and through downloadable files. Where an unrounded and rounded value provided by the resolution source differ with respect to the resolution of this market, the unrounded value will be used.

This market resolves around Oct 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final average number of ships transiting the Bab el-Mandeb Strait during September will be compared against the market’s defined ranges. Once official data sources publish the figures, the market settles automatically based on which range matches the verified result.
Several signals could shift this market before Oct 1, 2026. Geopolitical developments — such as naval conflicts, sanctions, or security alerts in the strait — often cause rapid adjustments. Extreme weather events, like hurricanes or storms, may disrupt shipping lanes and lower transit numbers. Additionally, economic shifts affecting global trade volumes, or new infrastructure projects altering routing patterns, can influence trader sentiment and move odds on Polymarket as new data emerges.
