Polymarket
This market tracks the average number of ships passing through the Strait of Hormuz on a daily basis as measured at the end of June. On Polymarket, the leading outcome—that there will be between 20 and 40 average daily transits on June 30—stands at 97.2%, while the outcome for 40 to 60 average daily transits holds 1.1%. Resolution will be determined by the finalized 7-day moving average of transit arrivals reported by IMF Portwatch. Watch for the IMF Portwatch data release on June 30, 2026, which will provide the official transit count used to settle this market.
This market will resolve according to the finalized 7-day moving average of transit calls (“Arrivals of Ships”) for the Strait of Hormuz that IMF Portwatch reports for June 30, 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. Data for a specific date must be finalized before it is considered for this market (namely, once the next date's data point is available, the previous one is finalized). This market will resolve as soon as the relevant data has been finalized. If the data for the specified date has not been finalized by the end of the third calendar day (ET) after the day on which such data is released, this market will resolve based on data published up to that point. Additionally, if the relevant data is not released and finalized 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 the applicable resolution time will 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.
Prediction markets like Polymarket differ fundamentally from sportsbooks in that they aggregate trader beliefs about real-world events rather than offering fixed odds on sports outcomes. Sportsbooks set odds to balance liability; prediction markets derive odds from continuous supply and demand. For maritime traffic forecasts, prediction markets may reflect analyst reports, shipping indices, and geopolitical risk assessments more directly than traditional sportsbooks, which rarely cover such specialized logistics events. This makes prediction market pricing a distinct signal of informed trader conviction.
On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Polymarket, this event is priced as a range-based outcome market where traders buy and sell shares corresponding to different average ship counts. Each outcome bucket represents a specific traffic band, and the price of each share reflects the collective probability assigned by the market. As new shipping data, sanctions announcements, or regional tensions surface, traders adjust positions, moving prices up or down. The final settlement price depends on verified data reported at market close on Jun 30, 2026.
Key catalysts include geopolitical tensions in the Middle East, sanctions or trade policy changes affecting oil and shipping routes, military incidents or blockades, fluctuations in global oil demand, and weather disruptions. Announcements from shipping indices, port authorities, or maritime intelligence firms can shift trader expectations about traffic volume. Regional stability reports, OPEC production decisions, and broader economic slowdowns also influence shipping patterns. Any credible threat to freedom of navigation through the Strait typically increases uncertainty and can trigger sharp market repricing.
