Seats meet politics
Who can actually form a government?
Seat totals use the final election result. A mathematical majority does not automatically mean the parties will form a government.
S + V + MP + C
176seats in the final result · a majority requires 175M + SD + KD + L
173seats in the final result · a majority requires 175176/ 349 seats in the election result
The seats may suffice, but C rejects V in government. A majority is therefore not a completed coalition.
An outright majority describes seat arithmetic. Forming a government also requires party conditions to be compatible or tolerated.151/ 349 seats in the election result
Seats for three red-green parties. The model does not assume other parties will tolerate the government.

Party leaders and stated positions on government
Dated public statements, checked 6 Sept 2026. These are sourced context, not model odds.
Magdalena AnderssonParty chair and prime minister candidate
Leadership source · ↗- DECLAREDS seeks a mandate for an Andersson-led government
Magdalena Andersson says she seeks voters' mandate to become prime minister and lead a government pursuing broad cooperation.
The statement identifies a prime minister candidate but does not fix which parties would join or tolerate the government after the election.Social Democrats · effective from ↗
Ulf KristerssonParty leader and prime minister candidate
Leadership source · ↗- DECLAREDM campaigns for Kristersson and a four-party government
Ulf Kristersson has declared himself the Tidö grouping's prime minister candidate and said that M, SD, KD and L will join the government if the grouping wins.
This is a publicly declared government alternative. The model can test its outright seat majority, but cannot determine whether all post-election negotiations succeed.SVT Nyheter · effective from ↗
Jimmie ÅkessonParty chair
Leadership source · ↗- DECLAREDSD is to enter government if the Tidö parties win
Åkesson and Kristersson have presented an alternative including all four Tidö parties, with SD taking government responsibility.
The statement gives SD ministerial posts but does not specify individuals or exact portfolios. Those details are not modelled.SVT Nyheter · effective from ↗
Nooshi DadgostarParty chair
Leadership source · ↗- DECLAREDV demands cabinet participation if its votes are needed
The congress-adopted election platform says V will not support or permit a government it does not join if V's votes are needed to form it.
S, V, MP and C may reach 175 seats without their stated conditions being compatible. An outright majority is therefore not a completed government agreement.Left Party · effective from ↗
Elisabeth Thand RingqvistParty leader
Leadership source · ↗- DECLAREDC names Andersson as its most likely partner
Elisabeth Thand Ringqvist has identified Magdalena Andersson as her most likely prime minister partner. C demands lower emissions, more jobs, lower taxes and investment in rural areas.
C may be decisive in tolerating a prime minister even outside government. Its vote against a nominee can therefore matter more than whether a four-party grouping reaches 175 seats.SVT Nyheter · effective from ↗ - DECLAREDC wants to unite S, C and KD in the centre; MP has also been mentioned
C's proposed centrist alternative includes S, C and KD, with a possible opening for MP. MP has rejected the alternative.
This is C's proposal. There is no joint agreement, and KD has since refused to permit an Andersson-led government.Aftonbladet · effective from ↗ - DECLAREDC wants a centrist government without V or SD influence
The Centre Party campaigns for a centrist alternative without influence from the Left Party or Sweden Democrats.
C's conditions must be considered alongside V's and MP's demands for government participation. A combined seat count does not imply an agreement.Centre Party · effective from ↗
Ebba BuschParty leader
Leadership source · ↗- DECLAREDKD campaigns for continued Tidö cooperation
Ebba Busch has said KD supports Tidö cooperation and has no red lines about which Tidö parties may join the government.
KD is part of Kristersson's declared seat grouping, but specific ministerial posts are explicitly not assigned before the election.SVT Nyheter · effective from ↗ - DECLAREDKD rejects Andersson, even if it leads to an extra election
Ebba Busch has said KD is prepared to vote against Magdalena Andersson as prime minister all the way to an extra election.
According to this statement, C's preferred centrist government lacks KD's support. It is a dated political condition, not a model forecast.SVT Nyheter · effective from ↗
Amanda Lind & Daniel HelldénCo-spokespersons
Leadership source · ↗- DECLAREDMP demands a place in a red-green government
Amanda Lind has said MP must join a future red-green government and will vote against governments it does not join.
MP's seats therefore cannot automatically be counted as tolerance for an S-led government excluding MP.TV4 Nyheterna · effective from ↗ - DECLAREDMP rejects C's S + C + KD alternative
Amanda Lind has rejected the C leader's preferred centrist government of S, C and KD, citing differences in climate policy.
C's preferred centrist government therefore lacks a joint declaration from the parties it seeks to unite.Aftonbladet · effective from ↗
Simona MohamssonParty chair
Leadership source · ↗- DECLAREDL accepts SD in a four-party government
The Liberals' extraordinary congress confirmed the new position: the party is ready to admit SD to government if the Tidö parties win.
This removes the previous red line against SD ministers, but L must also clear the parliamentary threshold to win its own seats.SVT Nyheter · effective from ↗
The prime minister appoints ministers after the vote
Once Parliament approves the Speaker's prime minister nominee, the elected prime minister appoints the other ministers. Seats confer negotiating strength but do not automatically determine who receives a ministerial portfolio. Politicalverse therefore assigns no probabilities to individual future ministers.
Constitutional context from Swedish Parliament ↗The register describes constitutional rules and dated public statements. It does not model prime ministers, governing parties or ministerial posts and contains no odds for individuals.

Forecast questions
A precise answer needs a precise question
7 DEFINITIONS
All classified as MODEL
The questions are defined in advance so their outcomes can be checked after the election. Each probability is the share of simulations meeting the condition. It says nothing about which outcome you should favour.
Will S, V, MP and C win at least 175 seats?
95.2%
This measures seat strength. It does not mean C and V accept the same government.
Definition and uncertainty
Yes if S, V, MP and C together receive at least 175 of 349 seats in the Election Authority's final parliamentary result. The forecast is a model, not a market price or a promise.
Will the Tidö parties win at least 175 seats?
4.8%
L's threshold position is the largest individual risk to the declared seat grouping.
Definition and uncertainty
Yes if M, SD, KD and L together receive at least 175 seats in the final result. The forecast is a model, not a market price or a promise.
Will the Liberals clear the parliamentary threshold?
27.2%
The threshold makes small movements around four percent very important for seat allocation.
Definition and uncertainty
Yes if the Liberals receive at least 4.00 percent of valid votes nationally. The forecast is a model, not a market price or a promise.
Will the Christian Democrats clear the parliamentary threshold?
98.6%
The model weighs the polling centre against historical forecast errors and variation between pollsters.
Definition and uncertainty
Yes if the Christian Democrats receive at least 4.00 percent of valid votes nationally. The forecast is a model, not a market price or a promise.
Will the Social Democrats be the largest party?
99%
Being the largest party affects negotiations but does not automatically appoint the prime minister.
Definition and uncertainty
Yes if the Social Democrats receive the highest national vote share among the modelled parliamentary parties. The forecast is a model, not a market price or a promise.
Will SD win more seats than M?
76.1%
This affects the balance of power within the right-wing grouping but does not automatically determine the prime minister.
Definition and uncertainty
Yes if the Sweden Democrats receive more parliamentary seats than the Moderates in the final result. The forecast is a model, not a market price or a promise.
Will exactly seven parties enter Parliament?
71.7%
In the central forecast, L loses its seats while the other seven parties win representation.
Definition and uncertainty
Yes if exactly seven of today's eight parliamentary parties win at least one seat. The forecast is a model, not a market price or a promise.

DIAGNOSTICS
Derived from the same snapshot
A guide to the forecast: the party closest to the threshold, the likely largest party, the seat grouping closest to 175 and the widest seat interval.
27.2 % above the parliamentary threshold
Small movements around four percent can shift many seats between the blocs. This is the model's most sensitive threshold at present.
99 % simulation frequency
Social Democrats is largest in this share of simulations. That strengthens a negotiating position but does not appoint a prime minister.
S + V + MP
The central scenario is 13 seats from the majority threshold. Political compatibility is treated separately as sourced context.
Sweden Democrats
The widest 80% interval shows where seat outcomes vary most across simulations. Outcomes beyond the interval remain possible.

Historical coverage in leave-one-election-out validation. An 80% interval is not a guarantee.
How to read the validation: The frozen design is assessed against 2010–2018, with 2022 reserved as a locked holdout. The repository reproduces the fixed model, not an exhaustive parameter search. Four elections are a small sample; historical errors may understate new political shifts.
Method and data integrity
From a raw row to a reproducible snapshot
OFFICIAL data, POLLs, MODEL outputs and political CONTEXT are kept separate. This section shows the flow, version identifiers, cross-checks and limitations accompanying publication.
Published polls
The current window includes 45 polls from 8 polling series. A poll becomes available on its publication date.
Time and pollster
Newer fieldwork carries more weight, with a 28-day half-life. One pollster receives at most 25 % of the realised weight.
Historical forecast error
4 comparable elections inform the parties' joint uncertainty. 2002 and 2006 remain in the official history but are excluded from the eight-party test.
Seats, every time
10,000 possible vote-share outcomes pass through the same tested seat engine, with 29 constituencies and adjustment seats.
INTEGRITY RECORD
Every forecast can be reproduced.
The snapshot, source dataset, code version and checks are shown together. If an update fails validation, the last accepted forecast stays published.

Source correction: Novus, fieldwork 24 Aug 2026–30 Aug 2026. Publication date is recorded as 2 Sept 2026 according to the primary source ↗, instead of the aggregate file's 1 Sept 2026. The original file is preserved.
Limitations accompanying every number- Four elections have fully comparable eight-party polls. The frozen design is assessed on 2010–2018; 2022 is a locked holdout. OTHER is a combined residual category assumed to contain no eligible new party. Historical errors offer no guarantee for 2026, and seats are not the same as governing power.
- Other is an uncertainty category that keeps vote shares exhaustive, but receives no seats in v1. The entry of a new named party is therefore not modelled.
- The interview total does not count unique people; the same respondent may appear in multiple polls.
- Polls describe opinion during fieldwork. Campaign events after the data cutoff are not included in the forecast.
- The model calculates seats for government alternatives. Party conditions are presented as dated, sourced context without invented probabilities.
- Exact comparison-figure ties are resolved by a seeded, reproducible draw in the simulation. The record shows the frequency of elections requiring such a draw.
