Mean of 5 draws (0.07, 0.07, 0.10, 0.10, 0.10). (0) Resolution check: nothing shows the condition met. The resolution-source read and all research through Oct 7 show active, escalating war: Saudi-backed 'Operation Yemen Dawn' (launched Oct 4), 100 coalition jets, and Houthi strikes on Medina, Jazan and Najran. No Saudi or Houthi statement accepting any dated ceasefire exists. (a) About 24 days remain until Oct 31, 11:59 PM ET. (b) Status quo is No: Alimi says de-escalation is 'exhausted' and operations will run until liberation. Officials report Riyadh refuses truce talks while the Houthis hold Bab al-Mandeb territory, and the Houthis reject a narrow truce in favour of a broader settlement. (c) NO scenario: the offensive grinds into a stalemate through October, with mediation feelers via Oman, the UN or Hamas/Qatar producing only talk of talks, which the rules exclude. (d) YES scenario: heavy losses and a stalled front, plus a UN Security Council presidential statement or Grundberg/Oman push, lead both sides to announce a dated nationwide cessation of hostilities, as in the 2022 Ramadan truce. The base rate for that within weeks of launching a maximalist offensive is very low. The market sits at 10.5% and is trending down 21 points over 30 days. The related 'effective ceasefire by Oct 31' market trades at 7.5%. The strict two-party, dated, general-suspension criteria and the fresh escalation justify shading slightly below the market, to about 7%.

report: current state
- [2026-10-04] Yemen's Presidential Leadership Council (PLC) Chairman Rashad al-Alimi announced a major Saudi-backed military operation, "Operation Dawn of Yemen/Yemen Dawn," a counteroffensive against the Houthis, saying it was "launched to restore state institutions, liberate the capital, Sana'a, and end the coup by the terrorist Houthi militias." https://www.fdd.org/analysis/2026/10/06/yemeni-government-forces-launch-saudi-backed-counteroffensive-against-houthis/ - [2026-10-05] A Saudi-led coalition deployed 100 fighter jets in round-the-clock air support, destroying 324 "high-value" Houthi targets , and Yemeni forces claimed to retake Dhubab/Bab al-Mandeb and Mocha; Houthis disputed the gains. https://www.thenationalnews.com/news/gulf/2026/10/05/yemen-government-forces-claim-bab-al-mandeb-gains-as-saudi-coalition-says-100-jets-join-houthi-offensive/ - [2026-10-05] Pakistan and Turkey pledged to mobilize troops in Saudi Arabia to defend it from further Houthi attacks , under the Makkah mutual-defense pact, in response to the escalation — indicating allied military buildup rather than de-escalation. https://en.wikipedia.org/wiki/2026_Yemen_offensives - [2026-10-06] Houthi forces struck Saudi Arabia's Jazan and Najran airports, injuring three people, while Yemeni government forces announced a major operation meant to retake all territory held by the Houthis , including al-Waziyah district. https://www.cfr.org/global-conflict-tracker/conflict/war-yemen - [2026-10-02] Reporting citing Western/regional officials indicated Saudi leaders are unwilling to enter any truce negotiations with the Houthis as long as the group controls territory along the Bab al Mandeb Strait; the Houthis view themselves as holding the upper hand and will not accept a ceasefire unless Saudi accepts their demands . https://www.criticalthreats.org/analysis/iran-update-october-2-2026 - [2026-09-19] CNN reported neither the US nor its key ally Saudi Arabia has a clear plan to beat back the group , amid rapid Houthi territorial advances including seizure of a Red Sea island, underscoring the deteriorating, non-ceasefire trajectory heading into October. https://www.cnn.com/2026/09/19/politics/frustration-houthis-saudi-arabia-iran - [~2026-09-19] An unconfirmed Lebanese press report (Al Akhbar) said Saudi Arabia conveyed through Oman a new proposal to the Houthis including a two-week ceasefire and the opening of direct talks ; this was never corroborated by an official Saudi or Houthi announcement and appears to have been overtaken by the subsequent offensive. https://www.jpost.com/middle-east/article-909031 - [2026-10-05] Iran-aligned press (Tehran Times) reported the initiative for a Saudi-Houthi political track had come from the government in Sanaa itself, with Ansarallah asking Hamas to intervene through the Qatar-Turkey-Egypt mediation channel working on Gaza, hoping mediators could open a political and negotiating track between Sanaa and Riyadh — a mediation feeler, not a dated ceasefire commitment. https://tehrantimes.com/news/530783/Behind-Hamas-s-offer-to-mediate-between-Yemen-and-Saudi-Arabia - [2026-10-05] The same report notes Ansarallah's position explicitly rejects a narrow truce: the objective was to move beyond a simple de-escalation, since a truce alone could never produce lasting peace and stability, with remaining economic, financial, and political issues also needing to be addressed — implying any deal sought is a broader political settlement, not an imminent dated ceasefire. https://tehrantimes.com/news/530783/Behind-Hamas-s-offer-to-mediate-between-Yemen-and-Saudi-Arabia - [2026-10-04/06] CNN confirms the offensive is ongoing and intensifying, with Yemeni government soldiers fighting near Taiz to retake key positions near the Bab al-Mandeb Strait... as they launch a renewed campaign to roll back recent gains made by the Iran-backed Houthi movement , with fighting continuing as of the Oct 6 update. https://www.cnn.com/2026/10/04/middleeast/yemen-offensive-houthis-intl - [2026-09-24 update] CFR's conflict tracker overview still frames the situation as a potential reignition of civil war, noting Houthi strikes on Saudi Arabia's Abha Airport in July 2026 now threaten to reignite the civil war , with the tracker's "Recent Developments" section (last substantively updated) referencing only the defunct 2022 ceasefire and the stalled 2023 Oman-mediated talks — no active ceasefire process is documented. https://www.cfr.org/global-conflict-tracker/conflict/war-yemen BOTTOM LINE: As of October 7, 2026, Saudi Arabia and the Yemeni government (backed by Saudi airpower, plus new Pakistani/Turkish troop pledges) are in the midst of an active, escalating multi-front offensive ("Operation Yemen Dawn/Dawn of Yemen") against the Houthis, not de-escalating; reported "ceasefire" chatter has been limited to unconfirmed, secondhand reports of informal Omani-channel feelers and a vague Houthi-initiated mediation request via Hamas for a broader political track, none of which constitutes a dated, mutually-announced suspension of hostilities. NOT FOUND: No official Saudi government or Houthi/Ansarallah statement proposing or accepting any dated ceasefire; no confirmed Oman-mediated truce announcement for October 2026; no scheduled formal talks or summit before October 31, 2026 found in available sources.
report: base rate
- [2022-03-29] The only successful nationwide Saudi-Houthi/Yemen ceasefire was announced via a coalition statement ahead of Ramadan, effective March 30, 2022 — the sole historical "Yes" precedent in this reference class since 2015. "The coalition hereby announces the cessation of military operations in Yemen as of 0600am (0300 GMT) on Wednesday, March 30, 2022." - [2023-10] UK Parliament research found the April 2022 truce was "the first nation-wide ceasefire in the conflict for six years was agreed in April 2022. The truce was renewed twice but expired in October 2022." — showing even a "successful" truce lapsed into informal de-escalation rather than a renewed formal deal, a pattern of years-long negotiation producing only partial/informal outcomes. - [2023-04] A major round of direct Saudi-Houthi talks in Sana'a (April 2023) raised hopes of an announcement "before Eid" but "raises hopes of a breakthrough in the quagmire conflict" ultimately produced no signed ceasefire — talks continued without an announced deal for years afterward. - [2023-12-23] The closest formal step toward a broader deal was the UN roadmap, where "the United Nations Special Envoy for Yemen, Hans Grundberg, announced that representatives of the Houthi movement and the internationally recognized government committed to 'a set of measures to implement a nationwide ceasefire.'" This was never fully implemented as a Saudi-Houthi agreement proper. - [2024-2025] CFR's tracker notes that despite years of mediation, "Peace talks between Saudi and Houthi officials, mediated by Oman, resumed in April 2023... However, concrete progress remains elusive, and the first official Houthi visit to the Saudi capital since the war began, on September 14, yielded nothing beyond optimistic statements." This underscores a historical base rate of high-profile talks repeatedly failing to produce a dated, signed ceasefire. - [2025-05-06] The only recent precedent of a clean, fast "ceasefire announced" event in this conflict family was the US-Houthi (not Saudi-Houthi) ceasefire: "On May 6, 2025, a ceasefire deal between the United States and the Houthi movement in Yemen—brokered by Oman—took hold, ending the March–May 2025 United States attacks in Yemen." This shows Oman-mediated deals CAN be announced quickly (within ~2 months of strikes) when both sides have strong incentive, but it was bilateral US-Houthi, not Saudi-Houthi, and narrower in scope. - [2026-05-12] A CRS report just before the current war noted "Saudi-Houthi talks, brokered by the UN Secretary-General's Special Envoy for Yemen, have continued in Amman, Jordan, but no new steps toward implementation of a UN-sponsored conflict resolution roadmap have been announced." — i.e., even in relative calm, years of talks produced no new dated ceasefire. - [2026-09-17] Current cycle's diplomatic opening: "Saudi Arabia has requested that Oman mediate a two-week ceasefire with Yemen's Houthis, seeking to discuss all 'humanitarian' demands and potentially announce an agreement at the end of that period." This two-week ceasefire proposal was reported but, per later events, not accepted by the Houthis. - [2026-10-05] Instead of a ceasefire, escalation sharply accelerated: Yemen's PLC launched "Operation Yemen Dawn" with Saudi air support aiming to retake Sana'a, described as "the largest campaign against the Houthis since the collapse of the 2022 truce." - [2026-10-05] The National reported "Operation Yemen Dawn had been launched to restore state institutions, retake Sanaa and end the Houthi 'coup'... The fighting quickly ground to a bloody stalemate with most front lines stalled." This is the opposite direction from a ceasefire and reflects a maximalist war aim replacing negotiation. - [2026-10-07] Base-rate pattern across 11+ years of this conflict: formal ceasefires are rare (one true multilateral instance in 2022), take many months to over a year of sustained negotiation to materialize even under favorable conditions (e.g., post-Saudi-Iran detente in 2023 still yielded no deal over 2+ years), and tend to emerge only after a decisive military stalemate or major external pressure — conditions not yet present in the current escalatory phase. BOTTOM LINE: The historical base rate for a fully "announced" Saudi-Houthi ceasefire is very low — only one comparable nationwide agreement in over a decade (April 2022), achieved after prolonged multilateral pressure, while repeated 2023–2026 negotiation rounds (including a Sept 2026 two-week ceasefire proposal) consistently failed to produce a dated agreement and the conflict has instead escalated into a major new offensive as of early October 2026, making a within-weeks announcement by Oct 31 historically atypical absent a sudden shock (e.g., decisive battlefield outcome or major-power imposed truce). NOT FOUND: No polling, prediction-market track record, or expert-elicitation base rate specific to "time from ceasefire proposal to formal announcement" could be located; no evidence of a currently active, advanced Saudi-Houthi (as opposed to US-Houthi) negotiation track with a specified effective date as of October 7, 2026.
report: yes case
YES means: Saudi Arabia and the Houthis each issue (jointly or separately) a declarative, dated announcement of a mutually agreed, general suspension of direct military engagement between them, confirmed by official statements and/or credible-reporting consensus, by October 31, 2026, 11:59 PM ET. - [2026-09-18] An unconfirmed Lebanese (Al Akhbar) report said Saudi Arabia, via Oman, proposed a two-week ceasefire with direct talks, after the US declined to intervene militarily and Pakistan's Mecca-pact support faltered — showing Riyadh was actively testing a diplomatic off-ramp just before the war escalated. https://www.jpost.com/middle-east/article-909031 - [2026-09-16] Reuters-sourced reporting confirmed a previously undisclosed US-Houthi meeting in Muscat, with Oman again facilitating; Houthi officials signaled they would avoid US/Israeli targets but explicitly excluded Saudi Arabia from any such assurance — showing Oman's channel remains live and capable of producing quick bilateral deals, even if not yet a Saudi-Houthi one. https://www.timesofisrael.com/houthis-met-us-officials-in-oman-promised-not-to-hit-american-israeli-ships-sources/ - [2026-10-01] The UN Security Council's October forecast states Council members are actively considering whether to "adopt a resolution or presidential statement demanding an immediate nationwide cessation of hostilities by all parties," which — if it induced a Saudi/Houthi declarative acceptance — is the clearest near-term multilateral mechanism that could produce a qualifying announcement. https://www.securitycouncilreport.org/monthly-forecast/2026-10/yemen-91.php - [2026-08-10] UN Special Envoy Hans Grundberg has been "engaging intensively with the Yemeni parties, regional actors and global partners on options for de-escalation," and continues pressing for "a full cessation of hostilities and progress in negotiations between the parties" — an active, continuous mediation track with historical precedent (his Dec. 2023 "ceasefire steps" announcement) for sudden breakthroughs. https://press.un.org/en/2026/db260810.doc.htm - [2026-10-01] The same SCR forecast notes Russia and China have "adopted a more measured stance...urging a negotiated solution involving all relevant political forces in Yemen, including the Houthis," signaling continued great-power appetite for a Council-endorsed ceasefire push that could pressure Riyadh toward a dated truce announcement. https://www.securitycouncilreport.org/monthly-forecast/2026-10/yemen-91.php - [2026-10-05] Despite the offensive, The National reports Operation Yemen Dawn had "quickly ground to a bloody stalemate with most front lines stalled" — a stalemate is historically (per 2022 precedent) often the precursor condition that pushes both sides back toward Oman/UN-mediated truce talks, raising the odds of a rapid reversal to negotiations if losses mount. - [2026-10-05] Iran-aligned reporting indicates Houthi leadership (Ansarallah) itself initiated outreach via Hamas and the Qatar-Turkey-Egypt channel for a "political and negotiating track between Sanaa and Riyadh," demonstrating the Houthi side has an active, if nascent, diplomatic opening that could be formalized quickly under third-party (Gaza-style) mediation pressure. https://tehrantimes.com/news/530783/Behind-Hamas-s-offer-to-mediate-between-Yemen-and-Saudi-Arabia - [2026-10-01] The SCR forecast records that as of September both the 2022 UN truce framework and prior Council press statements (7 Aug, 18 Sep) explicitly "reaffirmed support for...a UN-led political process," giving any new ceasefire a pre-built diplomatic architecture (Grundberg's roadmap) to slot into rather than starting from scratch. https://www.securitycouncilreport.org/monthly-forecast/2026-10/yemen-91.php - [2026-10-01] The 2022 precedent shows a full nationwide ceasefire can be announced via a single coalition/UN statement on short notice once both sides assess military costs outweigh gains; with Yemen Dawn reportedly stalling and civilian/economic costs mounting (125 civilians killed/wounded, 125,000 displaced per Türk's Sept 24 statement cited in the SCR report), similar cost-benefit pressure could reproduce that pattern before Oct 31. https://www.securitycouncilreport.org/monthly-forecast/2026-10/yemen-91.php BOTTOM LINE: The most plausible YES path is a Grundberg/Oman-brokered nationwide cessation-of-hostilities announcement — potentially catalyzed by a UN Security Council resolution/presidential statement under consideration this month — building on the pre-existing Sept. 18 two-week-ceasefire feeler and the Houthis' own Oct. 5 mediation outreach, especially if Operation Yemen Dawn's reported battlefield stalemate raises both sides' incentive to settle quickly. NOT FOUND: No evidence of a scheduled Saudi-Houthi summit, a drafted/tabled UN Security Council ceasefire resolution text, or any official Saudi or Houthi statement proposing a new truce since the Sept. 18 Al Akhbar report; no confirmation that the Security Council's considered "resolution or presidential statement" has been drafted or scheduled for an October vote.
report: no case
YES means: Saudi Arabia and the Houthis announce, by October 31, 2026, a mutually agreed, dated suspension of direct military engagement (a qualifying ceasefire, truce, or broader deal with a dated stop-fighting clause). - [2026-10-05] Yemeni PLC Chairman Rashad al-Alimi stated explicitly in his offensive-launch address that "We have exhausted all opportunities for de-escalation with the Houthi militias," directly contradicting any narrative of imminent ceasefire talks and instead framing the moment as the end of the diplomatic track. https://english.alarabiya.net/News/middle-east/2026/10/04/yemen-announces-military-operations-against-iranbacked-houthis - [2026-10-05] Alimi's order was unconditional and open-ended: "We have issued our directives to the armed forces, security forces and all military formations to begin carrying out their assigned missions in accordance with the plan, until the [country is liberated], showing no fixed end-date or ceasefire trigger built into the offensive's design. https://alhurra.com/en/44265 - [2026-10-04] A field commander, Gen. Faraj Ghleis, described the campaign as moving from preparation to "the stage of decisive action and the beginning of liberation," and said operations would not be limited in scope and that their geographic reach would extend across all Yemeni provinces under Houthi control , signaling a maximalist, nationwide campaign incompatible with a near-term ceasefire. https://alhurra.com/en/44265 - [2026-10-04] Axios confirms this was not an improvised reaction but planned for many weeks by Yemen's internationally recognized government and Saudi Arabia , showing Riyadh's deliberate strategic choice of escalation over the Sept 17 two-week-ceasefire-via-Oman track reported earlier. https://www.axios.com/2026/10/04/yemen-saudi-houthis-counteroffensive - [2026-10-07] As of the latest dateline, fighting continues to intensify rather than de-escalate: Yemeni forces launched an operation to capture a strategic mountainous district from the Houthis as part of a wider push to retake the Red Sea coast and the Bab al-Mandeb Strait , with no diplomatic track reported alongside it. https://www.aljazeera.com/news/2026/10/7/yemeni-forces-launch-offensive-to-retake-houthi-held-al-waziiya-in-taiz - [2026-10-07] Al Jazeera's same-day report headline frames the state of play as "Houthis, Saudi-led forces claim victories as Yemen fighting rages on" — the dominant, most current framing is active combat, not negotiation. https://www.aljazeera.com/news/2026/10/7/yemeni-forces-launch-offensive-to-retake-houthi-held-al-waziiya-in-taiz - [2026-10-06] Per Wikipedia's running timeline, the Saudi-led coalition reported on October 6 it had destroyed a weapons depot housing 20 ballistic missiles in Saada and a missile launch site in Sanaa , confirming strikes deep in Houthi-held territory just a day before the question's effective "now," well past any ceasefire window. https://en.wikipedia.org/wiki/2026_Yemen_offensives - [2026-10-05] Gen. Turki al-Maliki's field reporting that the "324 'high-value' Houthi targets had been destroyed in the offensive, with 100 fighter jets taking part" demonstrates an operational tempo and scale that would be very costly to halt diplomatically within three weeks without a clear strategic pivot. https://www.thenationalnews.com/news/gulf/2026/10/05/yemen-government-forces-claim-bab-al-mandeb-gains-as-saudi-coalition-says-100-jets-join-houthi-offensive/ - [2026-10-05] OSINT613 reporting states Alimi "said de-escalation had failed and that operations" would continue, with analysts framing this as "the largest campaign against the Houthis since the collapse of the 2022 truce," underscoring that the scale of this operation historically correlates with prolonged conflict phases rather than quick negotiated endings. https://www.osint613.com/article/saudi-arabia-opens-its-largest-yemen-offensive-in-years - [2026-10-02] Western/regional officials cited by Critical Threats reiterate that Saudi leadership rejects any truce talks while the Houthis hold Bab al-Mandeb territory — a precondition unmet as of October 7, since government/Saudi forces claim only partial, contested gains in Dhubab and Mocha, with Houthis disputing even those. https://www.criticalthreats.org/analysis/iran-update-october-2-2026 - [2026-10-04] Allied mobilization (Pakistan/Turkey troop pledges under the Mecca Pact) signals a multi-national commitment to sustained military pressure rather than a diplomatic off-ramp, raising the political cost of a sudden Saudi ceasefire announcement before battlefield objectives (Sanaa, full coastal control) are met. https://en.wikipedia.org/wiki/2026_Yemen_offensives BOTTOM LINE: Every available primary-source statement from Yemeni/Saudi-coalition officials as of October 7, 2026 affirmatively declares that diplomacy and de-escalation have been "exhausted" and that military operations will continue until maximalist objectives (full liberation of Sanaa and all Houthi territory) are met, with no fixed end-date, no scheduled talks, and intensifying strikes reported through October 7 — strongly weighing against any dated ceasefire announcement materializing within the remaining three-plus weeks to October 31. NOT FOUND: No official Saudi government or PLC/Houthi statement proposing a ceasefire, truce, or negotiation date since the October 4-5 offensive launch; no evidence any mediator (Oman, UN, Qatar/Hamas channel) has secured a new, dated proposal post-escalation as of October 7, 2026.

(0) Resolution check: nothing shows the condition met. The resolution-source read and all research through Oct 7 show active, escalating war: Saudi-backed 'Operation Yemen Dawn' (launched Oct 4), 100 coalition jets, and Houthi strikes on Medina, Jazan and Najran. No Saudi or Houthi statement accepting any dated ceasefire exists. (a) About 24 days remain until Oct 31, 11:59 PM ET. (b) Status quo is No: Alimi says de-escalation is 'exhausted' and operations will run until liberation. Officials report Riyadh refuses truce talks while the Houthis hold Bab al-Mandeb territory, and the Houthis reject a narrow truce in favour of a broader settlement. (c) NO scenario: the offensive grinds into a stalemate through October, with mediation feelers via Oman, the UN or Hamas/Qatar producing only talk of talks, which the rules exclude. (d) YES scenario: heavy losses and a stalled front, plus a UN Security Council presidential statement or Grundberg/Oman push, lead both sides to announce a dated nationwide cessation of hostilities, as in the 2022 Ramadan truce. The base rate for that within weeks of launching a maximalist offensive is very low. The market sits at 10.5% and is trending down 21 points over 30 days. The related 'effective ceasefire by Oct 31' market trades at 7.5%. The strict two-party, dated, general-suspension criteria and the fresh escalation justify shading slightly below the market, to about 7%.

As of October 7, no supplied source documents a qualifying agreement, but the October 5 resolution-source read checked news and Wikipedia rather than official Saudi and Houthi statements, so the event is neither established nor impossible. Approximately 24 days remain until October 31 at 11:59 PM ET for both parties to publicly accept the same agreement providing a general suspension of direct military engagement with a specified effective date. I retain Polymarket's 10.5% YES anchor (10% bid/11% ask), because the research provides no demonstrably unpriced information warranting a departure. If today's trajectory persists, No wins: Axios (October 4) describes a planned Saudi-backed offensive, while Al Jazeera (October 7) reports continuing fighting rather than an imminent negotiated halt. Reduced fighting, negotiations, or a mediator's proposal would still produce No without both parties' qualifying acceptance, although a Saudi–Houthi agreement need not settle the wider Yemeni war. Yes could result if battlefield costs prompt a rapid Oman/UN-brokered truce, supported as a plausible pathway by existing mediation channels and The National's October 5 report of stalled fronts. The 2022 truce demonstrates that agreement is possible, but subsequent stalled negotiations and the absence of confirmed advanced talks argue against a breakthrough this month. Missing official-source coverage and uncorroborated diplomatic feelers limit confidence, while the strict mutual-announcement requirement keeps this forecast below the probability of mere de-escalation.

I anchor on Polymarket's live 10.5% Yes price (10% bid/11% ask) and retain it because the research provides no demonstrated unpriced informational edge. As of October 7, no supplied source documents a qualifying agreement, but one remains possible during the roughly 24 days before October 31 at 11:59 PM ET. The resolution-source fetch contains news and Wikipedia rather than official Saudi and Houthi announcements, so incomplete coverage creates a missed-announcement risk and argues against pushing No toward near-certainty. If nothing changes, No wins: Axios on October 4 described a deliberately planned Saudi-backed offensive, and Al Jazeera on October 7 reported continuing fighting, with no verified mutual acceptance of a dated ceasefire. A plausible No scenario is continued territorial bargaining followed by inconclusive talks or informal restraint, neither of which satisfies the announcement requirements; the stalled 2023–2026 roadmap supports this qualitatively, although the historical report's nationwide-ceasefire count is not a clean base rate for this bilateral question. A plausible Yes scenario is an Oman/UN-mediated breakthrough in which Saudi Arabia and Houthi leadership both publicly accept the same general suspension of direct engagement with a specified effective date, without necessarily ending Yemen's internal conflict. Reuters-sourced September 16 reporting indicates an operating Omani channel, while Security Council Report's October 1 forecast identifies possible diplomatic pressure, preserving a credible rapid-agreement pathway despite the offensive. However, the September ceasefire proposal and October 5 Houthi mediation outreach are unconfirmed or partisan-source reports rather than accepted terms, and no scheduled talks or advanced agreement were found, making that pathway a minority outcome.

(0) The condition has not already been met or become impossible: the October 5 resolution-source read found no ceasefire announcement, although it did not retrieve the designated official Saudi or Houthi sources, so both parties would still need to announce acceptance of the same qualifying, dated agreement. (a) About 24 days remain until October 31 at 11:59 PM ET. (b) If nothing changes, the market resolves No because current fighting and informal mediation feelers do not satisfy the explicit mutual-announcement requirement. (c) The clearest No scenario is that Operation Yemen Dawn continues through October, consistent with Al Jazeera's October 7 report of raging combat, the Saudi-backed campaign's maximalist objectives, and the absence of scheduled talks. (d) A Yes could occur if mounting losses and battlefield stalemate prompt Oman or the UN to broker a general cessation of hostilities that Saudi Arabia and the Houthis both formally accept with a specified effective date. Polymarket's 10.5% Yes price is the primary anchor, and the live diplomatic channels and 2022 precedent prevent a much lower estimate despite the escalation. I move only modestly below the market to 9.5% because the latest evidence shows deliberate military escalation, no advanced negotiation track, and a strict resolution standard that vague de-escalation statements would not meet.

Yes: 9% No: 91%
Mean of 5 draws (0.07, 0.07, 0.10, 0.10, 0.10). (0) Resolution check: nothing shows the condition met. The resolution-source read and all research through Oct 7 show active, escalating war: Saudi-backed 'Operation Yemen Dawn' (launched Oct 4), 100 coalition jets, and Houthi strikes on Medina, Jazan and Najran. No Saudi or Houthi statement accepting any dated ceasefire exists. (a) About 24 days remain until Oct 31, 11:59 PM ET. (b) Status quo is No: Alimi says de-escalation is 'exhausted' and operations will run until liberation. Officials report Riyadh refuses truce talks while the Houthis hold Bab al-Mandeb territory, and the Houthis reject a narrow truce in favour of a broader settlement. (c) NO scenario: the offensive grinds into a stalemate through October, with mediation feelers via Oman, the UN or Hamas/Qatar producing only talk of talks, which the rules exclude. (d) YES scenario: heavy losses and a stalled front, plus a UN Security Council presidential statement or Grundberg/Oman push, lead both sides to announce a dated nationwide cessation of hostilities, as in the 2022 Ramadan truce. The base rate for that within weeks of launching a maximalist offensive is very low. The market sits at 10.5% and is trending down 21 points over 30 days. The related 'effective ceasefire by Oct 31' market trades at 7.5%. The strict two-party, dated, general-suspension criteria and the fresh escalation justify shading slightly below the market, to about 7%.
