final rationale
Mean of 5 draws (0.77, 0.78, 0.81, 0.81, 0.81). (0) Not resolved: Sánchez remains PM as of 2026-10-03, with no dissolution decree and no investiture; YES still needs an election, a PP+Vox majority, a coalition deal and a successful investiture by 31 Mar 2028. (a) About 18 months remain; an election is legally required by 22 Aug 2027, leaving time for one investiture attempt, though a failed attempt and repeat election would run close to the deadline. (b) Status quo is a snap election (29 Nov 2026 is widely reported after the 2 Oct housing-decree defeat) or one in 2027; PP leads PSOE by about 6 points in aggregates, SocioMétrica gives PP+Vox about 207 seats, and Feijóo calls a PP-Vox pact 'la única solución', with regional PP-Vox deals as precedent. (c) NO: the race tightens (More in Common has PP 28.7 vs PSOE 27), PP+Vox fall short of 176, PNV and Junts veto a Vox-inclusive government as in 2023, and Sánchez is re-invested or a repeat election runs past the deadline; a PP-Vox standoff over Vox ministries or Feijóo's replacement as leader are smaller risks. (d) YES: an election in Nov 2026 or mid-2027 gives the right bloc a clear majority and Feijóo is invested within one to two months. The 80.5% market price is consistent with the Sánchez market at about 14% plus a small 'Other' residual; I shade slightly down for coalition friction and narrowing polls.

This is a Polymarket question, so polymarket_direct is the price anchor and resolution_source is required (Spanish government official info). Cross-venue signals come from Kalshi and Polymarket markets on the Spanish election timing and next PM. Wikipedia gives structured background on the next Spanish general election schedule and polling, and GDELT adds Spanish-language headlines on snap-election or no-confidence developments.

report: current state
- [2026-10-02] The Congress of Deputies rejected both of the government's housing decrees, with a majority of PP, Vox, Junts and UPN voting 'no' , a first-ever such alignment this legislature. Source: moncloa.com. - [2026-10-02] Feijóo (PP) publicly challenged Sánchez to call snap elections, declaring he is ready for Sánchez to convoke elections after the Congress defeat, saying "Estoy listo" . Source: moncloa.com. - [2026-10-02] Reports (El Diario, El Español) say government members consider a snap election "very probable," with 29 November now seen as the most likely polling date ; no official announcement had been made as of filing. Source: elespanol.com. - [2026-10-02] Per LOREG timing, the constitution allows dissolution followed by elections 54 days later; a decree signed/published early next week would put polling day at Sunday 29 November . Source: euronews. - [2026-10-02] Some PP insiders (El Confidencial) are skeptical the 29‑N date is confirmed and expect Sánchez to attempt one more budget push before deciding; Moncloa sources call reports of a snap vote possible "leaks to generate narratives." Source: euronews/noticiasdenavarra. - [2026-10-02] Sánchez has not confirmed early elections and continues to say he intends to run for a new term in the next general election, which he has scheduled for 2027 (i.e., exhausting the term). Source: en.wikipedia.org/Next_Spanish_general_election. - [2026-10-03] PolitPro's poll-of-polls aggregate (weighted average, as of 3 Oct 2026) shows PP leading at 32.4% vs PSOE 26.2%, with PP seen as "Strongest Force," 6.2 points ahead of PSOE ; model gives PP <1% probability of an absolute majority, PSOE <1%, Vox 0% , implying a PP–Vox coalition as most plausible route to a PP-led government. Source: politpro.eu. - [2026-09-27] SocioMétrica poll put PP at 33.9% and 145 seats, PSOE at 25.7% and 107 seats, and Vox at 18%, so that PP and Vox together would reach 207 seats , above the 176-seat majority threshold. Source: electografica.com. - [2026-09-22] Celeste-Tel survey showed PP's projected gain was more modest while PSOE fell sharply: PSOE at 25.4% and 101 seats, versus 31.9% and 121 seats in 2023 — a drop of 6.5 points and 20 seats . Source: democrata.es. - [2026-05-26] Earlier in the year, cross-party pressure (PP, PNV, Coalición Canaria, plus PSOE's own García Page and Felipe González) had already demanded Sánchez call early elections amid corruption scandals, though this did not force an immediate dissolution and Sánchez rejected calling elections then . Source: moncloa.com. - [2026-05-29] Junts (whose 7 votes are pivotal) explicitly ruled out backing a no-confidence motion with PP/Vox, with its spokesperson stating "No estamos aquí para poner y sacar gobiernos" , removing the no-confidence-motion route to replacing Sánchez outside an election. Source: moncloa.com. - [2026-10-03] No Spanish general election has been called yet; Sánchez remains incumbent PM and no investiture vote for Feijóo or anyone else has occurred. The Government of Spain's official site (lamoncloa.gob.es) still lists Sánchez as Prime Minister, with no dissolution decree yet published in the BOE as of this writing. BOTTOM LINE: Spain is in an acute, fast-moving political crisis — triggered by the 2026-10-02 defeat of the housing decrees — that could produce a snap election around 29 November 2026 if Sánchez calls it; current polling consistently shows PP leading PSOE by roughly 6-8 points with a plausible PP+Vox majority, which would be the most direct path for Feijóo to become PM, but as of 2026-10-03 no election has been called, no investiture has occurred, and Sánchez retains office with no confirmed timeline for a vote before the 2028 deadline. NOT FOUND: No official BOE decree or royal decree dissolving the Cortes had been located as of 2026-10-03; no confirmed election date from the Government of Spain; no post-election investiture results (since no election has occurred yet).
report: base rate
- [2026-10-02] Spain is weighing early elections after PP, Vox and Junts jointly voted down two government housing decrees; if Sánchez calls them at the earliest legal opportunity, the vote would be ~Nov 29, 2026, with the dissolution decree due by Oct 5; Moncloa says it is not yet "on that screen" and no call has been made. https://en.cibercuba.com/noticias/2026-10-02-u1-e135253-s27061-nid341728-espana-podria-ir-elecciones-anticipadas-sanchez - [2026-09-27] Pedro Sánchez maintains that elections will be held in 2027, has ruled out coinciding them with the municipal and regional elections in May, and has opened the door to a "technical advance," with the legal deadline for elections being August 22, 2027 at the latest. - [2026-09-02] If Sánchez exhausts the mandate, Spaniards would go to the polls on August 22, 2027 — i.e., the outside bound for a general election under current law is within this market's window (closes April 2028), giving ample time for a post-election investiture even if delayed. - [2026-07-06] A SocioMétrica poll for El Español found a 16-point gap between those who believe Feijóo will be the next PM versus Sánchez remaining, with the PP leader winning on every front measured. - [2026-05-25] An Invymark/laSexta poll found 55.7% of respondents believed Feijóo would be the next PM versus 43.9% who thought Sánchez would continue, and Feijóo also led as preferred president (54.8% vs 44.4%). - [2026-07-19] Feijóo publicly admitted that if the PP does not win an absolute majority, it will need an agreement with Vox, confirming what had been an open secret. This mirrors the 2023 precedent where a right-bloc majority was numerically insufficient. - [2026-05-26] An attempted PP censure motion showed PP (137 seats) plus Vox (33) and one defector reach only 171 votes, short of the 176 needed, with PNV or Junts support required and unlikely while Vox is involved. This illustrates the structural barrier to Feijóo reaching Moncloa outside a general election. - [2023-11-16 cite: historical base rate] In the last hung-parliament cycle, Feijóo's investiture attempt failed (29 Sept 2023) while Sánchez was successfully re-invested on 16 November 2023 , the only time since 1983 that a repeat election was avoided and a candidate was elected on the first investiture ballot — showing incumbents can retain power even after losing the popular vote plurality. - [Historical base rate] Since Spain's return to democracy, opposition-leader-to-PM transitions via election do occur (e.g., Rajoy 2011, Zapatero 2004, Sánchez's 2018 no-confidence motion) but are not routine; Feijóo already failed once (2023) despite PP winning the most seats, underscoring that "largest party" status does not guarantee an investiture win in Spain's fragmented, multi-nationalist-party parliament. - [2026-10-01] A More in Common poll put PP at 28.7% and PSOE at 27%, with Vox at 20.3%, showing a tightening race compared to July, with Abascal gaining 3.2 points and Feijóo losing 2.6 — polling leads for PP have narrowed recently even as "who will be next PM" expectation polls still favor Feijóo. - [2026-07-06] Feijóo is rated best even among Vox voters (5.5/10), compared with 4.3 for Abascal among PP voters, suggesting unusually broad cross-bloc acceptability that could ease a future PP-Vox pact relative to past cycles. BOTTOM LINE: Across mid-2026 polling, a plurality-to-majority of Spaniards expect Feijóo to become the next PM, and head-to-head "preferred PM" polls consistently favor him over Sánchez by 10-16 points; however, Spain's fragmented parliament historically makes investiture outcomes uncertain even for seat-plurality winners (Feijóo himself failed in 2023), and PP's most realistic path still requires a Vox-dependent coalition that regional/nationalist parties resist — so the base rate from this cycle's dynamics is "favored but not assured," contingent on an election actually being called and a workable majority materializing before the April 2028 deadline. NOT FOUND: No comparable betting-market (e.g., Oddschecker, PredictIt) odds specifically on "who will be next Spanish PM" were found distinct from the Polymarket contract itself; no official election date has been set as of 2026-10-03.
report: yes case
YES means: Alberto Núñez Feijóo officially becomes Prime Minister of Spain by receiving a confidence vote in the Congress of Deputies and being sworn in, before March 31, 2028. - [2026-10-02] The Congress's rejection of both housing decrees with PP, Vox, Junts and UPN voting together was an exercise of parliamentary architecture the PP leadership considers replicable in the Senate, where the Popular Parliamentary Group has 120 senators, its largest absolute majority since 2011 , showing PP's ability to build working anti-government blocs on substantive issues ahead of any election. Source: moncloa.com. - [2026-10-02] A snap-election path now has a defined legal mechanism: from the publication of the Royal Decree in the BOE, 54 days must elapse before the election; so if Sánchez set 29 November as the polling date, the decree would need to be published 54 days earlier — that is, 7 October , meaning a formal decision could crystallize within days. Source: orain.eus. - [2026-10-02] Government insiders quoted by El Diario reported Sánchez's team is studying calling general elections for 29 November , and other outlets add his "guardia pretoriana" is already modeling the scenario, indicating the snap-election option is live inside Moncloa, not just opposition rhetoric. Source: euronews/eleconomista. - [2026-10-02] Even Sumar, Sánchez's coalition partner, treated the scenario as imminent: Sumar convened an emergency meeting to activate the party machinery , suggesting the governing coalition itself is preparing for a possible vote rather than dismissing it. Source: telecinco.es. - [2026-10-02] PP demanded immediate action: Alejandro Fernández (PP) pressed Sánchez to call elections "el lunes o cuando le plazca," reflecting PP's calculation that it benefits from going to the polls now while riding the housing-decree defeat. Source: eleconomista.es. - [2026-10-02] Feijóo's camp views the housing-decree defeat as a template for broader opposition success: Génova's internal messaging frames it as proof PP positions itself as a solvent alternative against a Government that fails on its flagship legislative banner , reinforcing PP's electoral narrative heading into any campaign. Source: moncloa.com. - [2026-07-20] Feijóo has explicitly locked in the coalition mechanism needed to reach Moncloa without an absolute majority, stating a PP-Vox pact is "la única solución" to govern if PP falls short, and citing Vox's 3.5 million voters as legitimate partners — removing ambiguity about his willingness to form a right-bloc government. Source: moncloa.com. - [2026-08-23] Feijóo has already rehearsed this negotiating framework in government: he has championed the deals already reached with Vox in Extremadura, Aragón, Castilla y León and Andalucía, arguing these pacts have served to "give stability" and were closed in accordance with the legal order , giving a proven template for a national PP-Vox coalition agreement. Source: moncloa.com. - [2026-10-02] PP's unified front with Vox and Junts on the housing vote is the first time this legislature all three opposition blocs aligned against the government simultaneously, per moncloa.com's framing of the Vox flank remaining delicate, with Friday's voting coincidence not prejudging any future investiture, but the housing issue becoming the axis of the electoral narrative — indicating momentum without full commitment, but a thin wedge toward eventual investiture cooperation. - [2026-10-02] Procedurally, defeat of the decrees does not itself force Sánchez's resignation or elections: losing the decree vote does not oblige Sánchez to resign nor does it by itself trigger elections , meaning the YES path still requires Sánchez's affirmative decision to dissolve, which had not been taken as of October 3. - [2026-10-02] Should Sánchez instead delay, the outer legal deadline remains within the window: Spain's law requires elections by August 2027, and after a defeat of this scale, commentators note the political "cuenta atrás" has begun for Feijóo's "una última bala" opportunity, underscoring that this cycle (2026-27) is seen as his best realistic shot at Moncloa. Source: edubayon.substack.com. BOTTOM LINE: The most direct and currently most newsworthy path to YES is a snap election — legally executable via a BOE decree as early as 6–7 October 2026 for a 29 November 2026 vote — in which PP, polling clearly ahead of PSOE, would need a PP-Vox coalition (a mechanism Feijóo has publicly embraced and already tested regionally) to secure an investiture; this path is actively being discussed by both government and opposition insiders, though as of October 3 no decree has been signed and Sánchez retains sole legal authority to trigger it. NOT FOUND: No confirmation that Sánchez has signed or published a dissolution decree as of October 3, 2026; no official election date announcement; no evidence of a formal PP-Vox coalition agreement or seat allocation beyond rehearsed regional templates and general Feijóo statements of willingness.
report: no case
YES means: Alberto Núñez Feijóo receives a Congress of Deputies confidence vote and is formally sworn in as Prime Minister of Spain, forming a new government, before 2028-03-31 23:59 ET. The dimension below argues for NO (Feijóo does NOT become PM by the deadline). - [2026-10-02] Losing the housing-decree votes carries no automatic legal consequence for Sánchez: a legal analysis stresses that losing the vote on the decrees does not oblige Sánchez to resign nor does it by itself trigger elections , so the "crisis" framing does not mechanically force any path to a Feijóo investiture. (euronews.es) - [2026-10-02] Even insiders disagree on whether a snap vote is coming: El País reporting (via El Confidencial Digital) says Sánchez has decided to take some time, not yet determined, before announcing the date of the next general election , and PP figures themselves doubt a 29 Nov vote, expecting a final attempt with the budget first — i.e., the status quo (Sánchez continuing, no election called) remains a live, credible outcome rather than a formality. - [2026-10-02] If a dissolution decree were signed this week, LOREG timing fixes the vote for exactly the 54th day after the call — meaning even the fastest plausible path still leaves a full campaign period before any ballot is cast, with nothing guaranteed until votes are counted. - [Constitutional mechanism] Article 99.5 of the Constitution provides that if two months pass from the first investiture vote without any candidate winning the confidence of Congress, the King will dissolve both Chambers and call new elections — this is not a hypothetical: it has already been triggered twice in Spain's history (2016, 2019), illustrating that even a PP plurality after an election does not guarantee Feijóo clears the investiture hurdle on the first attempt, and failure resets the clock by months. - [2025-07-07] PP leadership has explicitly pre-committed to a self-defeating fallback: the PP has committed that, if it fails to win a sufficient majority to govern alone, Feijóo will call new general elections if Santiago Abascal demands to be part of the government , with PP sources confirming Feijóo is willing to force a repeat election if Vox demanded entering government in exchange for supporting a hypothetical investiture . If this stance holds, a PP plurality without an outright PP+Vox seat majority could produce another failed/delayed investiture rather than a swift Feijóo government. - [2026-10-01/02] Vox's parliamentary conduct shows no softening of leverage: Vox maintains its conditions for future investitures even while tactically aligning with PP on votes, and PP itself still has Vox as the delicate flank, since Friday's vote alignment does not prejudge any future investiture — the coalition-formation friction that already produced Feijóo's 2023 failure remains unresolved. - [2026-08-23] Feijóo himself continues to dodge confirming a Vox coalition, saying only he wants a government with the greatest possible democratic legitimacy rather than committing to coalition terms — the same ambiguity that stalled 2023 negotiations persists 14 months later. - [2026-09-03] The current legislature's other pivotal partners remain hostile to the PP-Vox axis: Junts' spokesperson has called Sánchez "disabled" to continue governing, but Junts has not shifted toward backing a PP/Vox alternative; Ferraz sources note Junts will not break the legislature over a single control session , underscoring that no non-electoral route (censure motion) is opening up either, consistent with Junts' earlier refusal to help "install and remove governments." - [2023 precedent, directly on point] Feijóo's own history as PP leader is one of investiture failure despite winning the most seats: his 2023 bid collapsed and Junts was left as kingmaker, with speculation over Feijóo's own future following the PP-led bloc's underperformance ; the full cycle from the July 2023 election to Sánchez's successful investiture took until 16 November 2023, a roughly 3.5-month formation period that could, if repeated after a 2026/27 election, push a Feijóo investiture dangerously close to or past comfortable margins if any single attempt fails and the Art. 99.5 clock restarts. - [Structural arithmetic] PNV has previously stated on the record that it had not changed its position and would not negotiate with the PP to form a government in which Vox participates — if PP+Vox fall even a few seats short of 176 in any future election (unlike the single favorable SocioMétrica projection), this historical PNV veto remains a hard wall against a Feijóo government, replicating 2023's dynamic. - [2026-10-02] No formal step has actually been taken: as of filing, the president has not announced an early call and has not expressly linked his remarks to elections or a dissolution of the Cortes , reinforcing that the entire "Feijóo becomes PM" pathway still depends on a chain of uncertain future events (dissolution → election → winning bloc → successful first-round investiture) none of which has yet occurred. BOTTOM LINE: The status-quo inertia case is strong: no dissolution decree exists, Sánchez retains full discretion and incentive to delay or avoid elections, and even if an election is eventually called, Spain's Article 99.5 mechanism plus PP's own pledge to prefer a repeat election over conceding to Vox demands, plus PNV's standing veto on any Vox-inclusive government, replicate the exact conditions under which Feijóo's investiture already failed once in 2023. NOT FOUND: No confirmed dissolution decree or official election date as of 2026-10-03; no post-hoc data on whether the "no more than one abstention" margin referenced for Junts/PNV/Podemos actually held in the Oct 2 housing-decree vote beyond the headline results already reported; no PP-Vox coalition agreement template specific to a prospective 2026/27 national government.

(0) Not resolved: Sánchez remains PM as of 2026-10-03, with no dissolution decree and no investiture; YES still needs an election, a PP+Vox majority, a coalition deal and a successful investiture by 31 Mar 2028. (a) About 18 months remain; an election is legally required by 22 Aug 2027, leaving time for one investiture attempt, though a failed attempt and repeat election would run close to the deadline. (b) Status quo is a snap election (29 Nov 2026 is widely reported after the 2 Oct housing-decree defeat) or one in 2027; PP leads PSOE by about 6 points in aggregates, SocioMétrica gives PP+Vox about 207 seats, and Feijóo calls a PP-Vox pact 'la única solución', with regional PP-Vox deals as precedent. (c) NO: the race tightens (More in Common has PP 28.7 vs PSOE 27), PP+Vox fall short of 176, PNV and Junts veto a Vox-inclusive government as in 2023, and Sánchez is re-invested or a repeat election runs past the deadline; a PP-Vox standoff over Vox ministries or Feijóo's replacement as leader are smaller risks. (d) YES: an election in Nov 2026 or mid-2027 gives the right bloc a clear majority and Feijóo is invested within one to two months. The 80.5% market price is consistent with the Sánchez market at about 14% plus a small 'Other' residual; I shade slightly down for coalition friction and narrowing polls.

(0) Not resolved. Sánchez is still PM, no dissolution decree has appeared in the BOE as of 2026-10-03, and no investiture vote has taken place. La Moncloa's page shows nothing new. (a) There are about 18 months until the 31 March 2028 deadline. A general election must legally be held by 22 August 2027, which leaves room for an investiture, and even one repeat cycle under Art. 99.5 would be tight but possibly feasible. (b) Status quo: Sánchez stays until an election in 2026 or 2027. The question then turns on who is invested afterwards. Polling consistently has PP leading PSOE by roughly 2–8 points, with Vox at 18–20%, so a PP+Vox combined majority above 176 seats is the modal outcome (e.g. SocioMétrica's 207 seats). (c) NO: PP slips, as in More in Common's narrowing 28.7 vs 27. PP+Vox then falls a few seats short, PNV and Junts veto any Vox-dependent government, and Sánchez is re-invested as in 2023. Alternatively, a PP–Vox standoff over Vox entering government forces a repeat election that pushes past the deadline. (d) YES: Sánchez calls a 29 November 2026 snap election after the housing-decree defeat, or simply runs to 2027. PP+Vox win a majority, and Feijóo, who has publicly embraced a Vox pact and already done regional deals with them, is invested. I anchor on the Polymarket price of 80.5% (Sánchez's own market sits at about 14%). I shade slightly lower for the recent poll tightening, the 2023 precedent of a plurality failing to convert, and small risks of Feijóo being replaced as leader or a deadline overrun.

No supplied source documents a qualifying Feijóo investiture and swearing-in: the October 3 research reports Sánchez remains incumbent, while the official La Moncloa fetch contains only navigation and cannot independently verify that report. About 18 months remain until March 31, 2028, 11:59 PM ET, and the reported August 22, 2027 latest election date leaves roughly seven months for government formation even without an early election. If Sánchez simply continues without a new confidence-backed government through the deadline, the parent market resolves Other and this binary contract resolves No. The strongest YES scenario is that PP and Vox obtain a workable majority and install Feijóo as the next qualifying prime minister: PolitPro's October 3 aggregate puts PP ahead 32.4% to 26.2%, while SocioMétrica's September 27 projection gives the two parties 207 seats against 176 needed, although that seat estimate is only one poll. A NO scenario is that electoral shifts or coalition disagreements prevent his investiture, allowing Sánchez or another candidate to form the next government, as Feijóo's failed 2023 investiture demonstrates; repeated elections could also exhaust the deadline. I give greater weight to July 2026 reports of Feijóo's willingness to cooperate with Vox than to the NO report's July 2025 refusal pledge, but no binding national agreement is documented, and neither an electoral victory nor caretaker service satisfies the required source-confirmed confidence vote and swearing-in. I therefore retain Polymarket's 80.5% YES anchor: the research supports favoritism but supplies no clearly unpriced development warranting a directional adjustment, particularly since the October 2 housing defeat does not legally force elections and the market has already risen two percentage points over the week.

No supplied source documents a qualifying new government: the official La Moncloa fetch returned only navigation, while the 3 October reporting says Sánchez remains incumbent, so Feijóo must still secure congressional confidence and be sworn in as the next qualifying prime minister. Roughly 18 months remain until 31 March 2028, 11:59 PM ET, and the reported statutory election deadline of 22 August 2027 leaves approximately seven months for government formation even without an early election. If today's status quo persists through the deadline without a qualifying investiture, the parent market resolves to Other and this contract resolves No; continued incumbency or caretaker service alone does not qualify. I retain Polymarket's live 80.5% Yes anchor, with its 80–81% bid/ask, because the research supplies no clearly unpriced evidence warranting a material adjustment; different-deadline and different-resolution markets provide context only. The strongest Yes scenario is a PP–Vox electoral majority followed by an agreement to invest Feijóo: PolitPro's 3 October aggregate puts PP at 32.4% versus PSOE's 26.2%, while SocioMétrica's 27 September projection gives the right-wing bloc 207 seats against 176 needed. A credible No scenario is electoral deterioration or failed coalition negotiations leading to Sánchez's re-investiture, another candidate taking office first, or repeated elections exhausting the deadline; Feijóo's failed 2023 investiture directly demonstrates that winning the most seats is insufficient. I discount the unconfirmed 2 October snap-election reports and the July 2025 anti-coalition pledge, given newer July 2026 statements contemplating Vox support, but conflicting accounts and the absence of a national agreement leave meaningful bargaining uncertainty. The 19.5% No allocation covers electoral reversal, alternative successors, bargaining failure and deadline risk, while the credible-reporting fallback makes pure official-website publication lag a relatively small settlement risk despite the unsuccessful official-source read.

(0) The condition has not been met: the official-source fetch contains no evidence of a Feijóo investiture, while the current-state review says Sánchez remains prime minister and no dissolution decree or confidence vote has occurred. (a) Roughly 545 days remain until March 31, 2028, and a general election is legally required by August 2027, leaving substantial time for government formation. (b) If the present officeholder and parliamentary situation simply persisted through the deadline, the outcome would be No. (c) No results if Sánchez is reinvested, PP and Vox fall short because PNV or Junts refuse support, or failed investitures and a repeat election delay government formation beyond the deadline; Feijóo's failed 2023 investiture demonstrates this risk. (d) Yes results if either a near-term snap election or the mandatory 2027 election gives PP and Vox a workable majority and Congress then invests Feijóo; PP leads PSOE by 6.2 points in PolitPro's aggregate, and SocioMétrica projected 207 PP-Vox seats. I retain Polymarket's 80.5% Yes anchor because the latest housing-vote crisis and snap-election speculation are probably reflected in its recent two-point rise, while the research provides no clearly unpriced fact warranting a material deviation.
4. Final plain mean of 5 draws
79% (62% confidence)
Yes: 79% No: 21%
Mean of 5 draws (0.77, 0.78, 0.81, 0.81, 0.81). (0) Not resolved: Sánchez remains PM as of 2026-10-03, with no dissolution decree and no investiture; YES still needs an election, a PP+Vox majority, a coalition deal and a successful investiture by 31 Mar 2028. (a) About 18 months remain; an election is legally required by 22 Aug 2027, leaving time for one investiture attempt, though a failed attempt and repeat election would run close to the deadline. (b) Status quo is a snap election (29 Nov 2026 is widely reported after the 2 Oct housing-decree defeat) or one in 2027; PP leads PSOE by about 6 points in aggregates, SocioMétrica gives PP+Vox about 207 seats, and Feijóo calls a PP-Vox pact 'la única solución', with regional PP-Vox deals as precedent. (c) NO: the race tightens (More in Common has PP 28.7 vs PSOE 27), PP+Vox fall short of 176, PNV and Junts veto a Vox-inclusive government as in 2023, and Sánchez is re-invested or a repeat election runs past the deadline; a PP-Vox standoff over Vox ministries or Feijóo's replacement as leader are smaller risks. (d) YES: an election in Nov 2026 or mid-2027 gives the right bloc a clear majority and Feijóo is invested within one to two months. The 80.5% market price is consistent with the Sánchez market at about 14% plus a small 'Other' residual; I shade slightly down for coalition friction and narrowing polls.
