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 3 days ago. Ages are as of when this page was built.

Final prediction market prices for "Shipping successfully targeted in Hormuz on...?". September 21 last traded at 92.9%. Next is September 29 at 90.5%. $184K has traded across 10 outcomes on Polymarket. The market closed on Sep 17, 2026.
This market will resolve to "Yes" if a kinetic strike is conducted on, or forceful seizure of control is taken of, a commercial ship within the defined area on the specified date, between 12:00 AM and 11:59 PM GST (UTC+04:00). Otherwise, this market will resolve to "No". The defined area consists of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman. An incident occurring outside these three bodies of water will not qualify, including in the Arabian Sea, the Gulf of Aden, or the Red Sea. No attribution is required. A qualifying incident will count regardless of the identity of the party responsible, regardless of whether any state or group claims responsibility, and regardless of whether responsibility is denied, disputed, or never established. Attacks on military vessels will not be considered. Missile/drone strikes targeting a ship that are intercepted or otherwise do not directly impact the vessel will not be considered, regardless of damage through debris. Seize control refers to forcefully boarding and taking control of a commercial ship. Qualifying incidents include, but are not limited to, drone and missile strikes, aerial bombings, and kinetic actions carried out by operatives in person. Damaged caused by mines will not qualify. The primary resolution source for this market will be a consensus of credible reporting. The occurrence, location, and timing of a qualifying incident will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, location, or timing of a relevant incident, this market will remain open until the earlier of: i) the confirmation of the occurrence, location, and timing of the incident based on a consensus of information available from the resolution sources or ii) 3 full calendar days (GST) from the date of the first credibly reported evidence of the incident. If this period would extend past the end date, this market will remain open to allow for 3 full calendar days to pass. If, at the end of the third calendar day, conflicting reports remain as to the occurrence, location, or timing of the incident, the incident will be judged on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information.
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%.
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.
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.
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.
