Analysis
This market displays extreme yield metrics (3115% implied yield on Yes) despite modest price movement (47¢ to 46¢ over 7 days), suggesting either severe mispricing or structural illiquidity issues given the $25.8k open interest against only $5k daily volume. With 14 days to resolution and a tight 2¢ spread, the 46% probability appears reasonable for a binary shipping threshold, though the 1031% realized volatility and high info arrival rate (3.2/hour) indicate significant uncertainty around actual transit data publication. The cliff risk index of 1 combined with approaching expiry warrants caution on position sizing, as final resolution depends entirely on IMF Portwatch data that could move the market sharply in either direction.
Resolution rules
This market will resolve to “Yes” if IMF Portwatch publishes a daily number of transit calls (“Arrivals of Ships”) for the Strait of Hormuz equal to or above the listed value for any date between market creation and April 30, 2026. Otherwise, this market will resolve to “No”. The number of daily transit calls/arrivals includes 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 daily number 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.
