About this market

Live prediction market odds for "Russia x Ukraine ceasefire agreement by...?". December 31, 2027 leads at 71.5%. Next is November 30, 2027 at 67.5%. $9.4M has traded across 15 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.

This market will resolve to “Yes” if there is a ceasefire agreement between Russia and Ukraine by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A ceasefire agreement refers to any mutually-agreed suspension of direct military engagement between Russia and Ukraine, which is either officially announced by both countries or confirmed by a consensus of credible reporting to have been mutually agreed by both countries. A broader peace deal, normalization agreement, political framework, truce, or humanitarian pause will qualify if it includes a mutually agreed suspension of direct military engagement, to be effective on a specified date. Agreements that outline future negotiations or de-escalation measures without an explicit, dated commitment to stop fighting will not qualify. Any form of informal understanding, backchannel communication, de-escalation without an announced agreement, or unilateral pause in hostilities will not be considered a ceasefire agreement. Only agreements which constitute a general pause in the conflict will qualify. Agreements which only apply to specific conflict categories (e.g. restrictions on certain target categories or certain locations) will not qualify. If a qualifying agreement is officially reached before this market’s end date, this market will resolve to “Yes,” regardless of whether the ceasefire agreement officially takes effect after that date. The primary resolution sources for this market will be official information from the governments of Russia and Ukraine and 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.
