About this market

Final prediction market prices for "U.S. forces seize another oil tanker by April 15?". April 30 last traded at 100%. $5.2M has traded across 1 outcome on Polymarket. The market closed on Apr 15, 2026.

This market will resolve to “Yes” if U.S. government forces seize an oil tanker or any other ship actively transporting oil between market creation and April 15, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. U.S. government forces refer to any active U.S. military (including U.S. Coast Guard), law enforcement, or intelligence personnel or contractors. Seizes refers to U.S. forces taking custody of or asserting operational control of the vessel, including boarding and taking control of the vessel, detaining the vessel indefinitely, or forcefully rerouting the vessel to a U.S.-controlled port. The resolution source for this market will be a consensus of credible reporting.

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.
