Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue, the oldest 196 days ago. Ages are as of when this page was built.

About this market

Final prediction market prices for "Will __ ships transit the Strait of Hormuz on any day April 8-12?". 10 last traded at 63.3%. Next is 20 at 22.7%. $51K has traded across 6 outcomes on Polymarket. The market closed on Apr 12, 2026.

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 within April 8 - April 12, 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 12, 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.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
