About this market

Final prediction market prices for "US strikes Yemen by...?". March 31 last traded at 0.1%. $383K has traded across 1 outcome on Polymarket. The market closed on Mar 31, 2026.

This market will resolve to "Yes" if the US initiates a drone, missile, or air strike on Yemen soil or any official Yemen embassy or consulate by the listed date, 11:59 PM ET. Otherwise, this market will resolve to "No". For the purposes of this market, a qualifying "strike" is defined as the use of aerial bombs, drones or missiles (including cruise or ballistic missiles) launched by US military forces that impact Yemen ground territory or any official Yemen embassy or consulate (e.g., if a weapons depot on Yemen soil is hit by an US missile, this market will resolve to "Yes"). Missiles or drones which are intercepted and surface-to-air missile strikes will not be sufficient for a "Yes" resolution regardless of whether they land on Yemen territory or cause damage. Actions such as artillery fire, small arms fire, FPV or ATGM strikes directly, ground incursions, naval shelling, cyberattacks, or other operations conducted by US ground operatives will not qualify. The resolution source will be a consensus of credible reporting. If no qualifying strike is confirmed by the resolution date this market will remain open until the end of the second day after the resolution time. If the date/time of a qualifying strike cannot be confirmed by a consensus of credible reporting by that time, it will resolve to "No" regardless of whether a strike was later confirmed to have taken place.

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.
