final rationale
Mean of 5 draws (0.07, 0.07, 0.09, 0.09, 0.09). (0) Nothing qualifies yet. The only signed Ukraine–Russia text in 2026 is the May 9–11 Victory Day truce with a prisoner exchange. Wikipedia calls it a temporary humanitarian pause, and the rules explicitly exclude humanitarian pauses and prisoner-exchange arrangements. No signed ceasefire or peace-process document has been reported as of Oct 10, 2026. (a) About 82 days remain until the Dec 31, 2026 11:59 PM ET deadline. (b) If nothing changes, the market resolves No. The Oct 9–10 Miami round produced no concrete agreements, and on Oct 10 Putin told Trump that an immediate resumption of trilateral talks was unlikely. Rubio called the war a stalemate, Putin ruled out even a long-range-strike ceasefire at Valdai, and no UAE trilateral date or leaders' summit is scheduled. (c) NO path: talks keep slipping, as they did after the Dec 2025 '90% done' claims and the missed June 2026 target. Winter escalation and the US–Russia diesel side-deal strain alignment further, and Ukraine's Article 73 referendum barrier blocks any territorial signature. (d) YES path: Trump forces a pre- or post-midterm breakthrough and Witkoff/Kushner carry a unified proposal to Moscow later in October. Kyiv then signs a framework or 'roadmap' or a general ceasefire text with Russia as a party; the rules' low bar means only Ukraine needs to sign. The anchor is Polymarket at 8.5% (bid 8, ask 9), down 2 points over 30 days. The sibling broader ceasefire market for Dec 31 sits at 15.5%, and Metaculus has a bilateral ceasefire before 2027 at about 6%. Given the fresh Kremlin pullback on Oct 10, which may not be fully priced, I shade slightly below the market.

- current state: As of October 10, 2026, talks are active and intensifying (Florida/Miami round Oct 9-10, prior Kyiv/Moscow visits in September, UAE trilateral talks "proposed and accepted in principle") but no draft has been finalized or signed, Russia continues to reject a broad ceasefire and insists on territorial/"root cause" demands, and no leaders' summit or signing date is scheduled — suggesting a signed Ukraine-Russia instrument by Dec 31, 2026 remains possible but far from assured given the historical p
- base rate: Across multiple vintages of this same conflict, expert/forecaster consensus (Metaculus, RAND/Glimt) has consistently and correctly assigned low probability to a signed Russia-Ukraine peace/ceasefire instrument by any given near-term deadline, and the closest historical analogue (Korea) took roughly two years of formal negotiation to produce a signed armistice; both lines of evidence point toward continued skepticism that a qualifying signed instrument will be concluded before end-2026.
- yes case: The negotiating scaffolding (20-point plan plus three companion security/economic documents, UAE as a working trilateral venue, Ukraine's declared readiness to sign various ceasefire/process formats) is substantially more mature than in prior wars at this stage, and the resolution's low bar (Ukraine-only signature, a "process" framework sufficing without a full ceasefire) means a late-2026 US-brokered push — especially if Trump personally forces a signing event before/after the midterms — remain
- no case: The most current evidence (Oct 8-10, 2026) shows the US side itself describing the war as a stalemate with no scheduled next trilateral meeting, Russia unilaterally pausing resumption of talks after blaming Ukraine's drone strikes, a US-Russia side deal straining the Ukraine-US alignment, and an unresolved constitutional referendum barrier to any territorial signature — all consistent with continuation of the multi-round pattern of missed deadlines, favoring NO by Dec 31, 2026.

report: current state
- [2026-10-09] Ukrainian negotiators (led by Rustem Umerov) met US envoys in Florida/Miami on Oct 9-10, with Kyiv's European partners joining; Witkoff and Kushner were tasked with pitching "new ideas," including a possible partial energy/grain-shipment ceasefire, but
one idea is a partial ceasefire that halts attacks on energy infrastructure and grain shipments, and while Ukraine has said it's willing to take that step, Russia has shown little willingness
.
- [2026-10-10] Zelensky publicly criticized Washington after
Trump struck a separate energy deal with Putin easing sanctions on Russian diesel while Ukrainian peace negotiators were in Florida
, calling the US-Russia arrangement unfair to Ukraine's negotiating position.
- [2026-10-01] Putin, speaking at the Valdai forum,
ruled out a ceasefire on long-range strikes with Ukraine as Moscow steps up its campaign of aerial attacks on Kyiv
, while saying
Russia would prefer to end the conflict in Ukraine through talks and wanted it to be a neutral country after the end of hostilities
.
- [2026-10-07] Ukraine's Foreign Minister Sybiha said
Ukraine is ready for different ceasefire formats, but only if the ceasefire covers both energy infrastructure and the Black Sea
, and Zelensky separately said Ukraine is ready for trilateral technical-level talks with the US and Russia.
- [2026-09-25] Kyiv and Moscow both confirmed plans to relaunch trilateral (US-Ukraine-Russia) talks, with the
United Arab Emirates proposed as the host of the new talks
, though no date/venue was finalized.
- [2026-09-15] UK Commons Library notes diplomacy resumed after a six-month hiatus (talks stalled since early 2026 due to US-Iran conflict), but assesses that
despite intensifying aerial strikes by both sides, and expectations that Russia will escalate its attacks over the coming winter, there is hope that further talks are on the agenda
, while cautioning that without a battlefield or red-line shift, further official talks are unlikely to achieve much.
- [2026-09-15] The same briefing reports that
Zelensky's offer to meet Putin on the sidelines of the G20 summit in the United States in December 2026 has reportedly been rejected by the Kremlin
, with Peskov calling such talks "impossible" except in Moscow.
- [2026-10-01] Putin claimed Russia was ready to resume negotiations from Sept. 21 but blamed Kyiv for disrupting progress;
he claimed that Russia remained open to negotiations with Ukraine but would not halt the war while the talks were taking place
.
- [2026-01-05 to 2026-02-07 historical]: Earlier in 2026, negotiators claimed a deal was "90% ready" after Florida/Paris talks (per Jamestown, citing Dec. 2025/Jan. 2026 reporting), and Zelensky said the US wanted a deal by June 2026 — that deadline passed without a signed agreement, underscoring a pattern of repeated missed deadlines.
- [2026-09-05/06] First-ever Witkoff/Kushner visits to Kyiv and Moscow in this round produced only modest atmospherics: Russian aide Ushakov called talks "substantive" but
gave no indication that Russia was prepared to compromise on its previous demands for peace, including territorial concessions by Ukraine, instead highlighting "significant advances" by Russian forces and reiterating "root causes" arguments
.
- [2026-10-08] Axios reported the Trump administration is
hoping to reach a diplomatic breakthrough ahead of the midterm elections and before brutal winter weather grips Ukraine
, indicating continued US pressure for progress but no finalized text.
- No written, signed instrument meeting the market's resolution criteria (ceasefire or defined peace-process document with both parties' signatures, Ukraine's wet-ink or official e-signature) has been reported as of 2026-10-10; all reported outcomes remain exploratory talks, proposals, and partial/energy-ceasefire ideas, none of them signed.
BOTTOM LINE: As of October 10, 2026, talks are active and intensifying (Florida/Miami round Oct 9-10, prior Kyiv/Moscow visits in September, UAE trilateral talks "proposed and accepted in principle") but no draft has been finalized or signed, Russia continues to reject a broad ceasefire and insists on territorial/"root cause" demands, and no leaders' summit or signing date is scheduled — suggesting a signed Ukraine-Russia instrument by Dec 31, 2026 remains possible but far from assured given the historical pattern of missed deadlines (90%-done claims in Dec 2025/Jan 2026, a missed June 2026 target) and continuing combat.
NOT FOUND: No confirmed date/venue for the proposed UAE trilateral summit; no evidence of any Zelensky-Putin direct meeting being scheduled; no leaked or published full text of any near-final draft agreement; no official statement from Polymarket's resolution source (consensus of reporting) indicating imminent signature.
report: base rate
- **Historical base rate (this war)**: Metaculus community forecasts have repeatedly and consistently assigned very low probability to Russia-Ukraine ceasefire/peace deals before each prior deadline, and have repeatedly resolved "No": questions asking about a ceasefire "before 2024"
resolved No with a community estimate of 0.2% chance
, and "before 2026"
resolved No with a community estimate of 0.1% chance
. This is a strong track record of the reference class correctly predicting "No" for earlier deadlines in this same conflict.
- **Current Metaculus/RAND consensus (as of ~2026-10)**:
only 15% of global analysts believe the war could end or a lasting ceasefire be signed by the end of this year, while 50% (the median) of forecasters do not see a realistic peace agreement before December 2027
, with
the most pessimistic experts pushing the likely cessation of hostilities to May 2029
.
- **A related, slightly narrower Metaculus question** ("bilateral ceasefire in the Russo-Ukrainian conflict before 2027") was trading around
6% chance, with "Russia plans a new offensive in the summer" and "Putin has historically chosen escalation" cited as factors decreasing likelihood
.
- **Analogous outside-view process (RAND/Glimt/Metaculus collaboration, March-May 2026)**: forecasters converged on skepticism of near-term ceasefire;
the consensus was that a ceasefire was unlikely to begin before 2026, with a 72% probability for this outcome on RFI, 60% on Glimt, and 47% on Metaculus as of May 8
— i.e. this process has repeatedly slipped past forecasters' own medians.
- **Historical comparator — Korean War armistice**: the most commonly cited precedent for a major interstate war ending via signed armistice/peace instrument took far longer than one year of active talks:
negotiations for the armistice spanned over two years (1951-1953), with representatives meeting in Kaesong and later Panmunjom, and 158 meetings before any party agreed to sign
.
- **General interstate-war statistics**: across history, wars that drag on for years without quick resolution are the exception, not the rule —
since 1946, Correlates of War data counts 38 interstate wars worldwide, with an average duration of 2.1 years
— but the Russia-Ukraine war has already exceeded this average by a wide margin (into its fifth year), consistent with it falling into the tail of protracted, hard-to-resolve conflicts where peace treaties take disproportionately long or occur as armistices rather than full peace treaties.
- **Cease-fire failure rates once reached**: even when ceasefires are reached, they are not necessarily durable or convertible into full peace treaties quickly —
the average time for a cease-fire to fail was a little over six years, and for interstate wars the average length of a cease-fire that eventually failed was just over eight years
— underscoring that even a ceasefire (a lower bar than this market's "written instrument" requirement) is historically slow to convert into comprehensive peace.
- **Track record of over-optimistic political signals**: this process has repeatedly produced premature optimism that failed to convert into signed deals — e.g., Commons Library notes that
after talks with Trump at the end of December 2025, Zelenskyy said that 90% of a potential peace deal had been agreed, but three rounds of talks in UAE and Switzerland in late January/February 2026 did not achieve a breakthrough
, and later
Russia continued to demand Ukrainian withdrawal from remaining Donbas as a precondition, with Rubio and Kremlin spokespeople describing the conflict as a stalemate
.
- **Current (Oct 2026) expert/diplomatic assessment**: as of the most recent UK parliamentary briefing,
unless there is a strategic breakthrough by either side on the battlefield, or a shift in either country's red lines over territory and future security guarantees, further rounds of official-level talks are considered unlikely to achieve much
, and
trilateral US-Ukraine-Russia talks proposed for October 2026 have no agreed date and unclear seniority of attendees, particularly on the Russian side
.
- **Sibling Polymarket contracts (same event family, for calibration only, not this contract)**: as of early October 2026, the broader "Russia x Ukraine ceasefire agreement by...?" market priced December 31 at roughly 44% and October 31 at roughly 25%, while narrower/harder contracts such as "Will Ukraine agree to cede territory to Russia by...?" (Dec 31, 2026) were much lower (~11%), consistent with markets treating a full signed peace instrument (this question's bar) as substantially less likely than a mere ceasefire or talks milestone.
- **Reporting of pessimistic Ukrainian/Russian public opinion**:
a survey by a Ukrainian polling agency showed over 52% of Ukrainians believed the overall situation would not improve in 2026, while a Russian poll indicated public support for the special military operation stood at 65%
, suggesting limited domestic political pressure on either side to make the concessions needed to sign a comprehensive instrument.
NOT FOUND: A rigorous academic base rate specifically for "time from first formal direct negotiations to signed comprehensive peace treaty/ceasefire instrument" across a large sample of post-1945 interstate wars (only the Korean War case study and general interstate-war duration statistics were found); no official Kremlin or Ukrainian government statement in the last 30 days committing to a signing date.
BOTTOM LINE: Across multiple vintages of this same conflict, expert/forecaster consensus (Metaculus, RAND/Glimt) has consistently and correctly assigned low probability to a signed Russia-Ukraine peace/ceasefire instrument by any given near-term deadline, and the closest historical analogue (Korea) took roughly two years of formal negotiation to produce a signed armistice; both lines of evidence point toward continued skepticism that a qualifying signed instrument will be concluded before end-2026.
report: yes case
YES means: Ukraine signs (wet-ink or official e-signature) a written document that also binds Russia as a party — a ceasefire, framework, or "defined process" text with principles/timetable — before Dec 31, 2026, 11:59 PM ET, regardless of whether Russia formally ratifies it.
- [2026-10-09] A new, high-intensity round of US-brokered talks opened in Miami/Hallandale Beach on Oct 9-10, explicitly aimed at producing "a unified proposal that Washington could subsequently discuss with Moscow," with Trump personally briefed by Witkoff/Kushner immediately beforehand and Treasury Secretary Bessent and NSC officials also engaged. https://www.kyivpost.com/post/86619
- [2026-10-09] The same reporting notes a further Witkoff/Kushner trip to Moscow "later in October" is already being planned to carry Kyiv's unified proposal to Putin, showing an active shuttle-diplomacy pipeline rather than a stalled process. https://www.kyivpost.com/post/86619
- [2026-10-04] Zelensky confirmed Ukraine has agreed to join US-proposed trilateral technical talks in the UAE, with Washington "proposing to somehow hold a meeting at the technical level in a trilateral format by the end of October" — a concrete near-term venue/format precedent, since UAE hosted the only two prior trilateral rounds (Jan 23-24 and Feb 4-5, 2026). https://www.anews.com.tr/world/2026/10/04/ukraine-agrees-to-us-proposed-trilateral-technical-talks-in-uae-zelensky-says
- [2026-02-05] The UAE-hosted trilateral format already has a track record of producing signed outputs between the parties (a 314-person POW exchange agreement concluded Feb 5, 2026), demonstrating the mechanism can produce a signed bilateral-adjacent instrument even amid deadlock on bigger issues. https://en.wikipedia.org/wiki/2026_United_States%E2%80%93Ukraine%E2%80%93Russia_meetings_in_Abu_Dhabi
- [2025-12-21] By December 2025, negotiators were working from four parallel near-complete documents — the 20-point plan, a "multilateral security guarantee framework," a bilateral "US Security guarantee framework for Ukraine," and an "economic & prosperity plan" — with talks focused on "timelines and the sequencing of next steps," indicating the drafting/architecture stage (the hardest technical work) is largely done and only political sign-off remains. https://www.aljazeera.com/news/2025/12/22/us-talks-with-russia-ukraine-in-miami-constructive-productive
- [2026-02-04] Zelensky stated negotiations on security guarantees with Western allies had been concluded, with the Coalition of the Willing committed to deploy troops "once a ceasefire was reached" and the US backing intervention if Russia violated it — meaning the security-guarantee annex, often cited as the toughest sticking point, had reportedly reached closure on the Ukrainian/Western side months ago. https://en.wikipedia.org/wiki/2026_United_States%E2%80%93Ukraine%E2%80%93Russia_meetings_in_Abu_Dhabi
- [2026-10-01] Even while rejecting a long-range-strike ceasefire, Putin said at Valdai that Russia would prefer to end the conflict through talks, consistent with the CSIS assessment that Putin previously called the US draft framework "the basis of a final peace settlement" — showing Moscow has not rejected the documentary architecture outright, only specific provisions. https://csis-website-prod.s3.amazonaws.com/s3fs-public/2025-11/251124_Cancian_Unfinished_Plan_Ukraine.pdf
- [2026-10-07] Ukraine's Foreign Minister Sybiha signaled flexibility on format, saying Kyiv is "ready for different ceasefire formats" if energy and Black Sea elements are covered, and Zelensky said Ukraine is ready for trilateral technical-level talks — showing Kyiv's negotiating posture is accommodating rather than resistant, consistent with being the first mover needed for a YES resolution (only Ukraine's signature is required by the resolution criteria).
- [2026-10-08] Axios reporting cited in colleague research shows the Trump administration is actively trying to engineer a "diplomatic breakthrough" timed to the Nov. 3 midterms and before winter — a concrete political incentive and deadline pressure from the US side pushing toward a signable document within the market's window, paralleling Trump's track record of imposing short "10-12 day" and "50-day" ultimatums on Russia that, while missed as deadlines, repeatedly re-energized drafting activity. https://globalnews.ca/news/11308864/russia-defies-trump-new-deadline-ukraine
- [2026-10-09] Trump's own diesel-sanctions-relief deal with Putin, struck the same day as the Miami talks, shows Trump is willing to make unilateral concessions to Russia to keep the broader negotiating track alive and extract later cooperation — a sign of continued top-level US investment in reaching some agreement, even if Ukraine objects to the manner. https://www.npr.org/2026/10/09/nx-s1-5996912/trump-says-u-s-to-get-diesel-from-russia-relaxing-pressure-on-moscow-to-ease-prices-before-midterms
BOTTOM LINE: The negotiating scaffolding (20-point plan plus three companion security/economic documents, UAE as a working trilateral venue, Ukraine's declared readiness to sign various ceasefire/process formats) is substantially more mature than in prior wars at this stage, and the resolution's low bar (Ukraine-only signature, a "process" framework sufficing without a full ceasefire) means a late-2026 US-brokered push — especially if Trump personally forces a signing event before/after the midterms — remains a plausible, if unconfirmed, path to YES.
NOT FOUND: No confirmed date for the "end of October" UAE trilateral meeting; no leaked near-final consolidated text combining the 20-point plan and three annexes as of Oct 2026; no Kremlin commitment to sign any document, only Putin's rhetorical openness to talks.
report: no case
YES means: Ukraine signs, with its own authorized representative's wet-ink or official e-signature, a written instrument also bearing Russia as a party that either ends hostilities/establishes a ceasefire or commits both sides to a defined peace process with stated objectives, principles, steps, and/or timetable, by Dec 31, 2026, 11:59 PM ET.
- [2026-10-10] Hours after the "productive" Miami/Florida trilateral session, the Kremlin itself undercut momentum:
Putin told Trump that Kyiv had undermined the possibility of an immediate resumption of trilateral peace talks by targeting Moscow with drones during last month's election, with Moscow having been prepared to resume direct negotiations but the timing derailed
, and Kremlin aide Ushakov said Russia must now reassess "when these negotiations can resume" (https://www.aljazeera.com/news/2026/10/10/putin-tells-trump-peace-talks-are-unlikely-cites-ukraine-drone-attacks).
- [2026-10-10] The Miami meeting itself produced no concrete text:
Witkoff said the talks helped identify areas for further consideration ahead of Washington's next engagement with Russia, but announced no concrete agreements, and his statement did not indicate whether further meetings would take place
(https://kyivindependent.com/us-ukrainian-european-officials-discuss-ending-russias-war-at-miami-meeting/).
- [2026-10-08] One day before Miami, Secretary Rubio publicly conceded the diplomatic track is stuck:
Russia's war against Ukraine is at a stalemate that could escalate into a broader regional conflict, which generally ends either through negotiations or escalation
, and
he cautioned that the US would not support efforts that had no prospect of progress
— an unusually candid signal from the administration driving the process that it does not see a deal as imminent (https://www.rferl.org/a/rubio-russia-war-spill-beyond-ukraine-borders/33872989.html, https://www.turkiyetoday.com/world/rubio-warns-ukraine-war-stalemate-very-dangerous-3229912).
- [2025-12-26/2026-06-30] Even if political terms were agreed, a structural legal obstacle to signature-with-territorial-content exists: Ukraine's constitution makes "issues of altering the territory of Ukraine" subject exclusively to a nationwide referendum (Article 73), while referendums and elections are barred under martial law — a documented "Referendum Paradox" that Ukrainian lawyers and NGOs have been wrestling with for ten months without resolution (https://scenarica.substack.com/p/the-referendum-paradox, https://kyivindependent.com/ngos-call-on-ukraines-government-to-drop-peace-deal-referendum-idea/).
- [2026-10-09] Trump's separate US-Russia diesel/sanctions-easing deal, struck mid-negotiation, visibly fractured the US-Ukraine negotiating alignment:
the ongoing talks have been overshadowed by the US-Russia diesel deal, with Trump blaming Ukrainian attacks on Russian refineries for surging diesel prices
, prompting Zelensky to call the arrangement a "gift to Putin" — evidence that Washington is making bilateral accommodations with Moscow that complicate rather than accelerate a joint Ukraine-Russia signed instrument.
- [2026-10-01] At Valdai, Putin reiterated maximalist/precondition-laden demands rather than softening them, consistent with prior reporting that Russia continues to resist a comprehensive ceasefire and insists on territorial and "root cause" concessions — a pattern unchanged since the September Kyiv/Moscow shuttle diplomacy.
- [2026-10-08] Battlefield intensity argues against imminent compromise:
more than 70 Ukrainian civilians died in a two-day attack, including more than 30 killed when two buses were hit by Russian missile strikes in Kramatorsk, one of the deadliest attacks in weeks
, undercutting any sense that either side faces pressure to make the concessions needed for a signed document rather than escalate further (https://www.sbs.com.au/news/article/marco-rubio-warns-of-ukraine-war-stalemate-as-us-pushes-for-peace-deal/crykrmg5o).
- [2025-11-28] The precedent of how fragile Ukraine's negotiating apparatus is under domestic pressure: chief negotiator Yermak's resignation came amid a $100m corruption scandal that
a U.S. official told Axios... could weaken Ukraine's negotiating position with Russia
, and while Umerov has since taken over, the episode illustrates how easily Kyiv's negotiating continuity and political capital can be disrupted — a risk that remains live given the scandal (dubbed "Mindichgate") is still under active investigation (https://www.axios.com/2025/11/28/zelensky-chief-staff-yermak-resign-scandal-corruption).
- [2026-09-15 to present] No trilateral leaders' summit, UAE host date, or Putin-Zelensky meeting has been confirmed; Peskov has called direct Putin-Zelensky talks outside Moscow "impossible," and Putin's Oct 10 comments suggest even working-level trilateral talks' resumption date is now open-ended rather than scheduled — meaning the status-quo trajectory into the Dec 31 deadline is one of indefinite postponement, not a scheduled signing.
- [Reference class] This is at least the fourth distinct round since Dec 2025 (Abu Dhabi/Geneva Jan-Feb, Florida "90%" claims, Sept Kyiv/Moscow shuttle, Oct Miami) to produce "constructive"/"productive" language without a signed text, reinforcing a now well-established pattern in this specific negotiation track of talks generating optimistic rhetoric that repeatedly fails to convert into a signed instrument within the stated timeframe.
BOTTOM LINE: The most current evidence (Oct 8-10, 2026) shows the US side itself describing the war as a stalemate with no scheduled next trilateral meeting, Russia unilaterally pausing resumption of talks after blaming Ukraine's drone strikes, a US-Russia side deal straining the Ukraine-US alignment, and an unresolved constitutional referendum barrier to any territorial signature — all consistent with continuation of the multi-round pattern of missed deadlines, favoring NO by Dec 31, 2026.
NOT FOUND: No confirmed next trilateral meeting date after the Oct 9-10 Miami round; no Kremlin statement committing to any Putin-Zelensky or full trilateral signing timetable; no official Ukrainian government response indicating how/whether it would sign a process document before resolving the referendum/Article 73 question.

(0) Nothing qualifies yet. The only signed Ukraine–Russia text in 2026 is the May 9–11 Victory Day truce with a prisoner exchange. Wikipedia calls it a temporary humanitarian pause, and the rules explicitly exclude humanitarian pauses and prisoner-exchange arrangements. No signed ceasefire or peace-process document has been reported as of Oct 10, 2026. (a) About 82 days remain until the Dec 31, 2026 11:59 PM ET deadline. (b) If nothing changes, the market resolves No. The Oct 9–10 Miami round produced no concrete agreements, and on Oct 10 Putin told Trump that an immediate resumption of trilateral talks was unlikely. Rubio called the war a stalemate, Putin ruled out even a long-range-strike ceasefire at Valdai, and no UAE trilateral date or leaders' summit is scheduled. (c) NO path: talks keep slipping, as they did after the Dec 2025 '90% done' claims and the missed June 2026 target. Winter escalation and the US–Russia diesel side-deal strain alignment further, and Ukraine's Article 73 referendum barrier blocks any territorial signature. (d) YES path: Trump forces a pre- or post-midterm breakthrough and Witkoff/Kushner carry a unified proposal to Moscow later in October. Kyiv then signs a framework or 'roadmap' or a general ceasefire text with Russia as a party; the rules' low bar means only Ukraine needs to sign. The anchor is Polymarket at 8.5% (bid 8, ask 9), down 2 points over 30 days. The sibling broader ceasefire market for Dec 31 sits at 15.5%, and Metaculus has a bilateral ceasefire before 2027 at about 6%. Given the fresh Kremlin pullback on Oct 10, which may not be fully priced, I shade slightly below the market.

(0) No source shows the condition met. The resolution-source read shows only the May 9-11, 2026 Victory Day truce. That was a humanitarian/prisoner-exchange pause, a category the rules explicitly exclude. No signed ceasefire or peace-process document with Russia as a party has been reported as of Oct 10, 2026. (a) About 82 days remain until the Dec 31, 2026 11:59 PM ET deadline. (b) Status quo is No: the Oct 9-10 Miami round produced no text. Rubio called the war a stalemate, and on Oct 10 Putin told Trump that resuming trilateral talks is now uncertain, citing Ukrainian drone strikes. The proposed UAE technical round has no date, and Peskov has rejected a Zelensky-Putin meeting outside Moscow. (c) NO path: further shuttle diplomacy and possibly a narrow energy/grain partial ceasefire, which would not qualify as sector-limited, while Russia keeps its territorial demands through winter. Ukraine's referendum/Article 73 barrier on territory also persists. (d) YES path: Trump forces a pre- or post-midterm breakthrough. Witkoff/Kushner carry the unified proposal to Moscow in late October, and a UAE trilateral session produces a signed framework or 'roadmap' text. The rules' low bar, a defined-process document with only Ukraine's signature required, would make that count. The market sits at 8.5% and has drifted down 2 points over 30 days. The Oct 10 Kremlin pushback and the repeated pattern of missed '90% done' deadlines, along with the ~6% Metaculus bilateral-ceasefire estimate, justify shading slightly below it.

No qualifying instrument is documented: the May 9–11 truce described by The Moscow Times and Wikipedia was an excluded temporary humanitarian/prisoner-exchange arrangement, so neither outcome is settled. Roughly 83 days remain until December 31, 2026, 11:59 PM ET, and resolution requires credible-reporting consensus that Ukraine signed a qualifying instrument by then, with Russia a party but not necessarily a signatory. I retain Polymarket's live 8.5% YES anchor (8% bid/9% ask), because the research provides no verified, clearly unpriced development warranting a departure. If nothing changes, No wins: the Kyiv Independent's October 10 account reports no concrete Miami agreement, while Al Jazeera's October 10 reporting says Moscow is reassessing when talks can resume. A NO scenario is continued territorial/security disagreement producing only energy, grain, humanitarian, or unsigned arrangements—diplomatic progress that still fails the market's scope and signature requirements. A YES scenario is renewed US shuttle diplomacy producing a Ukrainian-signed, war-wide ceasefire or framework committing both parties to defined peace steps, while deferring a final territorial settlement. The October 9 Kyiv Post reporting supports an active negotiating channel, but subsequent reports provide no finalized text or scheduled signing, and previous '90% ready' claims failed to deliver. I discount the base-rate report's inconsistent chronology and stale related-market prices, and give limited weight to the referendum objection because a qualifying framework need not immediately alter Ukraine's territory.

As of October 10, no supplied reporting documents a qualifying signed instrument: the Moscow Times/Wikipedia source read describes the May 9–11 truce as an excluded humanitarian/prisoner-exchange pause, so the event remains unresolved. Roughly 83 days remain until December 31, 2026, 11:59 PM ET, for an authorized Ukrainian representative to sign a qualifying document including both countries as parties. I retain this contract’s live Polymarket YES anchor of 8.5% (8% bid/9% ask), because the research supplies no demonstrably unpriced information warranting a departure; related ceasefire markets have different criteria. If nothing changes, No wins: October 10 Al Jazeera reporting describes Russian hesitation over restarting talks, while the Kyiv Independent reports no concrete agreement from Miami. A plausible NO scenario is continued territorial and security deadlock, with diplomacy producing only excluded energy, grain, or humanitarian arrangements. A plausible YES scenario is accelerated US shuttle diplomacy producing a Ukraine-signed framework committing both parties to defined peace steps; Russia’s signature and a comprehensive territorial settlement are unnecessary, weakening some arguments in the NO report. Documentary and classification risks constrain the forecast: even an announced breakthrough remains insufficient unless credible reporting establishes a timely authorized signature and qualifying scope, rather than merely an unsigned proposal or limited arrangement. Confidence is moderated by reliance on very recent reports and by the base-rate report’s inconsistent chronology, stale related-market prices, and overstatement of the settlement requirements, which I do not use as quantitative evidence.

(0) The condition has not already been met: the resolution-source review says the May 2026 three-day humanitarian truce is expressly excluded, and no qualifying signed instrument has been credibly reported; Ukraine would still need to sign one by December 31, 2026, 11:59 PM ET. (a) Roughly 82 days remain, a short window given that no final text, confirmed trilateral meeting, leaders' summit, or signing date exists. Polymarket's well-traded 8.5% Yes price is the primary anchor, while the related but differently worded year-end ceasefire market at 15.5% only provides context. (b) If nothing changes, ongoing hostilities and unsigned exploratory diplomacy produce No. (c) A straightforward No scenario is that Russia continues postponing talks after the alleged drone attacks, maximalist territorial and security disputes persist, and the latest US shuttle diplomacy ends like the earlier missed June target. (d) A Yes scenario is that the proposed UAE technical talks occur, US pressure converts the existing framework documents into a defined peace-process roadmap, and an authorized Ukrainian representative signs it—even without Russia's signature, which the rules do not require. The unusually permissive Ukraine-only signature rule and active US diplomacy justify a slight premium to the market price, but the latest Kremlin setback, repeated false dawns, and absence of a scheduled signing keep No strongly favored.
