About this market

Live prediction market odds for "Saudi troops fighting in Yemen by...?". December 31, 2026 leads at 14.5%. Next is October 31, 2026 at 4.1%. $120K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.

This market will resolve to "Yes" if active military personnel officially affiliated with Saudi Arabia enter Yemen for combat-related military purposes by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". For military personnel to qualify toward a "Yes" resolution, they must be 1) officially acknowledged as active military by Saudi Arabia; 2) be publicly acknowledged to have entered Yemen for a combat-related military purpose. For military personnel to qualify toward a "Yes" resolution they need be active duty and acknowledged as described above. Participation in a combat role is necessary for this market to resolve to "Yes" (e.g. military personnel providing training or intelligence support would not qualify toward a "Yes" resolution, however infantry engaging Yemeni forces, or personnel conducting combat operations from Yemeni soil would qualify toward a "Yes" resolution). Only members of the regular armed forces of Saudi Arabia will qualify toward a "Yes" resolution. Foreign fighters, private military contractors, mercenaries, or any other personnel recruited, paid, trained, equipped or directed by Saudi Arabia who are not members of the Saudi Arabian armed forces will not qualify, regardless of whether they operate under Saudi command or on Saudi Arabia’s behalf. Members of the armed forces of any other state, including those operating as part of a Saudi-led coalition, will not qualify. Personnel must be physically present on the terrestrial territory of Yemen, including its internal waters. Air or naval operations conducted from outside Yemeni territory, including air strikes, missile strikes, drone strikes and overflights, will not qualify toward a "Yes" resolution. The primary resolution source for this market will be official information from the government of Saudi Arabia, including the Saudi Ministry of Defense; however, a consensus of credible reporting will also be used.

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.
