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

About this market

Final prediction market prices for "Ukraine signs peace deal with Russia by March 31?". Yes last traded at 0.1%. $389K has traded across 1 outcome on Polymarket. The market closed on Mar 31, 2026.

This market will resolve to “Yes” if, Ukraine signs any written instrument (e.g., treaty, ceasefire/armistice, framework/“roadmap,” exchange of letters, or mediated agreement text) that: (i) includes both Ukraine and the Russian Federation as parties, and (ii) either ends hostilities/establishes a ceasefire or commits both sides to a defined process toward ending the war (i.e., stated objective of peace/normalization plus principles, steps, and/or a timetable) by March 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Only Ukraine’s signature is required; Russia’s signature or ratification is not. Localized, temporary, or issue-specific arrangements—such as airstrike-limitation or deconfliction protocols, humanitarian pauses, evacuation corridors, prisoner-exchange or trade/export arrangements, border/DMZ adjustments, or ceasefires limited to a particular sector/front/municipality—will not qualify. The document must bear a wet-ink or officially issued electronic signature of an authorized Ukrainian representative. Unsigned agreements (e.g., the 2023 Ohrid arrangement) will not qualify regardless of if they are otherwise officially enacted. The primary resolution source 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.
