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

About this market

Final prediction market prices for "Houthi military action against Saudi Arabia by March 31?". Yes last traded at 0.1%. $31K has traded across 1 outcome on Polymarket. The market closed on Mar 31, 2026.

This market will resolve to "Yes" if the Houthis initiate a drone, missile, or air strike that impacts Saudi Arabia's ground territory between market creation and the listed date, 11:59 PM Arabian Standard Time (GMT+3). 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 Houthi forces that physically impact land under Saudi Arabia's control. Saudi Arabia's ground territory, for the purposes of this market, refers to land internationally recognized as part of the State of Saudi Arabia as of market creation. Missiles or drones that are intercepted before reaching the ground, or surface-to-air missile strikes, will not qualify for a "Yes" resolution, regardless of whether debris lands on Saudi Arabia's soil or causes damage. The resolution source will be a consensus of credible reporting. If the date/time of a strike cannot be confirmed by a consensus of credible reporting by the end of the third calendar date after this market's end date, 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.
