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.

About this market

Live prediction market odds for "Russia x Ukraine ceasefire by end of 2027?". Yes leads at 54.5%. $150K has traded across 1 outcome on Polymarket. The market is expected to resolve by Dec 31, 2027.

This market will resolve to "Yes" if there is an official ceasefire agreement, defined as a publicly announced and mutually agreed halt in military engagement, between Russia and Ukraine by December 31, 2027, 11:59 PM ET. If the agreement is officially reached before the resolution date, this market will resolve to "Yes," regardless of whether the ceasefire officially starts afterward. Only ceasefires which constitute a general pause in the conflict will qualify. Ceasefires which only apply to energy infrastructure, the Black Sea, or other similar agreements will not qualify. Any form of informal agreement will not be considered an official ceasefire. Humanitarian pauses will not count toward the resolution of this market. A peace deal or political framework will qualify if it includes a publicly announced and mutually agreed halt in military engagement, effective on a specific date. Frameworks or agreements that outline terms for a future peace but do not include an explicit, dated commitment to stop fighting will not count. This market's resolution will be based on official announcements from both Russia and Ukraine; however, a wide consensus of credible media reporting stating an official ceasefire agreement between Russia and Ukraine has been reached will suffice.

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.
