Russia x Ukraine Ceasefire by...?

Resolution Criteria

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ceasefire goes into effect prior to this market’s end date, this market will remain open until the ceasefire is no longer in effect, or until the 10 calendar days have been reached. A ceasefire is considered no longer in effect when a consensus of credible reporting indicates the general suspension of hostilities has substantively ended across the primary theater.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.

Prediction markets show trading broadly distributed across multiple date thresholds for a Russia–Ukraine ceasefire, with December 31 and October 31 carrying the heaviest concentration of volume. Resolution requires a mutually agreed, publicly confirmed general suspension of hostilities across the primary theatre that holds continuously for at least 10 calendar days. The market closes on 31 December 2026, with resolution determined by a consensus of credible reporting.

Market structure

The market offers four date-threshold outcomes — May 31, June 30, October 31, and December 31, 2026 — each resolving 'Yes' if a qualifying ceasefire is both in effect and sustained for 10 consecutive calendar days by that date. Volume is concentrated on the two later dates, with the year-end December 31 outcome the heaviest-backed. Earlier date outcomes carry noticeably lower volume. Resolution relies on a consensus of credible reporting rather than any single official source.

Background

Russia's full-scale invasion of Ukraine, launched in February 2022, entered its fourth year in 2026 with no formal ceasefire in place. Intermittent diplomatic activity — including US-mediated contacts, European security framework discussions, and repeated calls from international bodies — has periodically raised expectations of a negotiated pause, though wide-scale fighting has continued across eastern and southern Ukraine throughout. Earlier short-term humanitarian pauses and partial arrangements, including holiday ceasefires, have not met the threshold of a general suspension of hostilities. The conflict remains one of the most actively traded geopolitical subjects across prediction markets globally, reflecting sustained uncertainty over the timing and shape of any eventual cessation of hostilities.

Key factors

Several structural factors shape whether and when a qualifying ceasefire could materialise. Diplomatic momentum — including the posture of the United States as a potential broker, the positions of European guarantor states, and the willingness of both Russia and Ukraine to enter a formal agreement — represents the primary decision point. Military conditions on the ground, including the state of front lines in Donetsk, Zaporizhzhia, and Kherson oblasts, influence both sides' negotiating incentives. Domestic political calendars in key mediating countries could create windows of either urgency or delay. The resolution criteria add a further structural layer: an agreement must be publicly confirmed by both parties or by credible reporting as mutually agreed, must constitute a general suspension across the primary theatre, and must hold for 10 continuous calendar days — requirements that exclude partial deals, unilateral pauses, or agreements limited to specific categories of activity. Any ceasefire that collapses before the 10-day threshold would not resolve the market 'Yes' for the relevant date outcome.
