About This Event
This market will resolve to "Yes" if a ceasefire between Russia and Ukraine goes into effect by 11:59 PM Eastern European Time (EET) on the specified date and remains continuously in effect for at least 10 calendar days. Otherwise, this market will resolve to "No". A ceasefire refers to any mutually agreed suspension of direct military engagement between Russia and Ukraine, which is officially announced by both countries or confirmed by a consensus of credible reporting to have been mutually agreed by both countries, and which constitutes a general suspension of direct kinetic military engagement across the primary theater of the overall conflict. A broader peace deal, normalization agreement, political framework, truce, or humanitarian pause (including holiday ceasefires) will count provided they otherwise qualify under this market’s rules. Any form of informal understanding, backchannel communication, de-escalation without an announced agreement, or unilateral pause in hostilities will not be considered a ceasefire. Agreements which only apply to specific conflict categories (e.g. restrictions on certain target categories or certain locations) will not qualify. Any calendar day (EET) during which the ceasefire is in effect (including the first day of the ceasefire) will count towards the 10-day total. The required 10 day period will end at 11:59 PM EET on the 10th day (inclusive). If a qualifying ceasefire goes into effect prior to this market’s end date, this market will remain open until the ceasefire is no longer in effect, or until the 10 calendar days have been reached. A ceasefire is considered no longer in effect when a consensus of credible reporting indicates the general suspension of hostilities has substantively ended across the primary theater. Temporary or technical lapses or expiration of a formal ceasefire term, isolated incidents, localized violations, or accusations alone will not invalidate the ceasefire provided the general suspension of hostilities across the primary theater continues. Where official government statements conflict with a consensus of credible field reporting, the reporting will take precedence over the government statements. The resolution source for this market will be a consensus of credible sources. Examples of qualifying Ceasefires: April 8, 2026 US–Iran ceasefire: The United States and Iran publicly announced and implemented a mutually agreed ceasefire framework intended to broadly halt direct military hostilities between the two countries. Despite subsequent maritime confrontations, alleged violations, isolated retaliatory strikes, and disputes regarding compliance, the broader ceasefire framework continued to function and widescale fighting across the primary theater did not resume. November 27, 2024 Israel–Hezbollah ceasefire: Israel and Hezbollah implemented a broadly operative ceasefire framework brokered through international mediators that substantially reduced hostilities across southern Lebanon and northern Israel, including the effective halt of Israel’s major ground offensive into Lebanon and a significant reduction in Hezbollah rocket fire. Although the ceasefire was not formally announced through a single joint declaration by both parties and public statements differed in framing and characterization, a consensus of credible reporting confirmed the arrangement had been mutually agreed and implemented in practice. Despite continued isolated strikes, alleged violations, and disputes regarding compliance, credible reporting broadly treated the ceasefire as remaining operational and widescale fighting across the primary theater of the conflict did not resume. Examples of non qualifying Ceasefires: November 24, 2023 Israel–Hamas humanitarian pause: Although it was a mutually agreed and publicly announced broad suspension of hostilities across Gaza, the ceasefire framework remained in effect for only approximately 7 days before wide-scale fighting resumed, failing the required 10-calendar-day duration requirement. Ceasefire violations prior to November 30, would not have invalidated the ceasefire. July 22, 2022 Black Sea Grain Initiative: Although Russia and Ukraine entered into internationally brokered agreements governing grain exports and reducing risks to commercial shipping in the Black Sea, the arrangement did not constitute a general suspension of direct military engagement across the primary theater of the war. Hostilities continued across Ukraine throughout the duration of the agreement and the arrangement applied only to specific categories of activity and geographic areas. May 2023 Sudan ceasefires (SAF–RSF): Although the Sudanese Armed Forces (SAF) and Rapid Support Forces (RSF) publicly agreed to multiple internationally brokered ceasefires, a consensus of credible reporting indicated that the general suspension of hostilities across the primary theater never substantively took effect and large-scale fighting broadly continued throughout the ceasefire periods. While some temporary reductions in violence and localized humanitarian access reportedly occurred in certain areas, artillery fire, airstrikes, urban combat, troop movements, and offensive operations continued across major parts of Sudan almost immediately after implementation. Credible reporting broadly treated the ceasefires as having failed or collapsed in practice despite technically remaining in force on paper.

What the contract measures
The saved event, "Russia x Ukraine Ceasefire by...?", lists two Polymarket contracts with different deadlines. The shared rule says the market resolves "Yes" if a ceasefire "goes into effect by 11:59 PM Eastern European Time (EET) on the specified date and remains continuously in effect for at least 10 calendar days." A ceasefire is defined as "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" [1].
The two contracts differ only in their deadline. One asks about a ceasefire by October 31, 2026, with a listed end time of 2026-10-31T21:59:00Z. The other asks about December 31, 2026, with a listed end time of 2026-12-31T21:59:00Z [1]. The rule is written in EET, while the listed times are in UTC, so readers should confirm how the two clocks line up before relying on either deadline.
Reading the snapshot
The provider observed these prices at 2026-10-15T03:00:06Z, and the record was retrieved at 03:11:40Z the same day [1]. These are observations from that moment, not current or executable quotes.
For the October 31 contract, the "Yes" price was 0.0165 and the "No" price was 0.9835. For the December 31 contract, the "Yes" price was 0.095 and the "No" price was 0.905 [1]. Each contract's two outcomes sum to one in the snapshot. The later contract shows a higher "Yes" price, which is consistent with a longer window, but the snapshot does not explain the difference.
The sample covers two of two markets from this one provider event. The record marks it as not partial and states that "all saved markets for these events are included" [1]. That does not show that Polymarket lists every possible outcome for this question. The ordering rule ranks markets by "Yes" price, so the two contracts were not chosen because of their prices. The record does not include volume for either contract, and volume would not indicate liquidity or the number of traders in any case.
What remains uncertain
The evidence does not show why either price is where it is, whether other platforms list similar contracts, or what has happened in the conflict since the snapshot. The prices should not be read as verified probabilities, and a gap between the two contracts is not an arbitrage opportunity, since their deadlines and resolution terms differ. The rule also requires continuous effect for 10 calendar days, a condition the snapshot does not evaluate.

Overview
This market asks whether a ceasefire between Russia and Ukraine will take effect by a specified date. According to the provider's contract rules, it resolves "Yes" if a ceasefire goes into effect by 11:59 PM Eastern European Time on that date and remains continuously in effect for at least 10 calendar days. Otherwise it resolves "No" [1]. The rules define a ceasefire as any mutually agreed suspension of direct military engagement between Russia and Ukraine that is either officially announced by both countries or confirmed by a consensus of credible reporting to have been mutually agreed [1]. The saved provider event is titled "Russia x Ukraine Ceasefire by...?" and is categorized under politics. Its saved markets include one for a ceasefire by October 31, 2026 and one for a ceasefire by December 31, 2026. The provider lists the December contract's end time as 2026-12-31T21:59:00.000Z and the October contract's end time as 2026-10-31T21:59:00.000Z, and reports the event as active [1]. These end times are contract closing times set by the rules. They are not announced dates for any ceasefire or negotiation. Because the contract depends on a ceasefire taking effect and then holding for 10 days, a "Yes" resolution requires both the start of the suspension and its continuation through that window. A ceasefire that is announced but does not remain in effect for 10 calendar days would not satisfy the rules as written [1].
Historical Context
The supplied background sources describe the conflict in broad terms. The war in Donbas began in April 2014, when Russian-backed paramilitaries began an uprising against the Ukrainian government, seized territory and declared independent states. Ukraine's military launched an operation against them but did not fully retake the territory. Russia's military was covertly involved, and the separatists were largely under Russian control. That phase ended when it was subsumed by the full-scale Russian invasion of Ukraine in 2022 [2]. A separate background article lists six deaths during the 2014 annexation of Crimea by the Russian Federation and 14,200 to 14,400 military and civilian deaths during the war in Donbas. It gives an estimate of between 1,274,000 and 2 million casualties during the Russian invasion from February 24, 2022 to June 2026 [3]. These figures are estimates reported in the source and are background only. They do not describe the current state of any ceasefire discussions.
Why It Matters
The contract measures whether a formal or mutually recognized pause in direct fighting between Russia and Ukraine begins within a set window and lasts at least 10 calendar days [1]. The rule's wording matters. A unilateral statement is not enough on its own, because the definition requires mutual agreement that is either officially announced by both countries or confirmed by a consensus of credible reporting [1]. The two saved contracts differ only in their deadlines. One closes at the end of October 2026 and the other at the end of December 2026 [1]. Each is a separate question with its own resolution rules, so a difference in how the two are priced reflects different timeframes and does not by itself indicate a mispricing. The background sources provide context for why such a question is followed closely, but they do not establish any particular negotiation status as of the current date [2][3].
