Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. 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 175 days ago. Ages are as of when this page was built.

About this market

Final prediction market prices for "Which countries will send warships through the Strait of Hormuz by April 30?". France last traded at 0.3%. Next is Germany at 0.2%. $3.3M has traded across 10 outcomes on Polymarket. The market closed on Apr 30, 2026.

This market will resolve to "Yes" if a national government, its military, or a broad consensus of credible reporting confirms that the listed country's warships transited through the Strait of Hormuz by April 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. A "warship transit" is defined as a military vessel passing through the Strait of Hormuz. Military cargo or support vessels will be considered “warships”; however, commercial or civilian vessels will not qualify. For the purposes of this market, only transits through the Strait of Hormuz will be considered, defined as passage through the narrowest portion of the waterway between Iran and Oman. Operations solely in the Persian Gulf, Gulf of Oman, or Arabian Sea without passage through this narrowest section will not qualify. Official confirmation by a national government or its military that its vessels transited through the Strait of Hormuz during the specified timeframe will resolve this market immediately. An overwhelming consensus of credible reporting confirming that such a transit occurred during the specified timeframe will also suffice. Qualifying confirmations include statements such as official announcements that a country has deployed naval vessels to transit or escort shipping through the Strait of Hormuz. Confirmations referring only to naval presence in the broader region, including the Persian Gulf, Gulf of Oman, or Arabian Sea, without confirmed transit through the Strait itself, as well as aerial operations, cyber operations, or actions by proxies or third parties, will not alone qualify. The primary resolution source for this market will be official information by the respective national governments or their militaries; however, an overwhelming consensus of credible reporting will also suffice.

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.
