Spain general election: polls and seat projection

When is the next Spanish election?

On today's polls, PP and Vox win an outright majority in more than 99 of 100 simulations.

Does a snap election pay?

What the numbers tell the person who has to decide.

PSOE
102 seats121 in 2023 · range 88–116
The bloc that re-elected Sánchez in 2023
143 seats179 in 2023 · majority in fewer than 1 of 100 simulations
PP + Vox
205 seatsrange 190–219 · majority in more than 99 of 100
PP alone
140 seatsoutright majority in fewer than 1 of 100

Today's polls give no arithmetic reason to go early: the PSOE would lose about 19 seats and the 2023 majority would be out of reach. A snap election would come from elsewhere: deadlock in Congress, the calendar, or a bet that the campaign moves votes.

The split left of the PSOE

Running apart, Sumar and Podemos win 11 seats. Together, on the same votes, they would win 20.

D'Hondt punishes mid-sized parties that split in small provinces. The gap (9 seats) is bigger than most groups in Congress.

Sumar 8 + Podemos 3 = 11
Sumar + Podemos = 20 (13–29)

Housing · the issue behind the snap election

Housing went from 2.5% in 2022 to 42.6% in 2026: it is now what worries Spaniards most.

Share of Spaniards naming housing among the country’s top three problems, CIS barometer month by month. In September 2026: 37.5%, ahead of the economy and immigration. 27.9% say it affects them personally.

What worries Spaniards most (CIS, September 2026)

  • Housing 37.5 %
  • Economy 21.6 %
  • Immigration 19.7 %
  • Politicians 13.9 %
  • Unemployment 11.5 %

Which party would handle housing best?

January 2025September 2026
PSOE 20.1 % 18.5 %
PP 18.0 % 14.4 %
Vox 14.1 % 14.4 %
Sumar 6.3 % not published
Podemos 4.0 % not published
None 23.8 % 22.6 %

Nobody convinces: “none” is the most common answer (22.6%). The PSOE still leads (18.5%) but is down 1.6 points since January 2025; the PP is down 3.6 and Vox holds (14.4%). So far the crisis has no clear winner.

Second model · Orbit (beta)

Orbit, our experimental model, reaches the same conclusion: PP and Vox win a majority in 89 of 100 simulations.

Orbit uses the same polls with different mathematics: it treats opinion as a position moving on a sphere rather than as an average. It is still in beta: we publish it for comparison, and a 50/50 mix with our main model, Harfang des neiges, gives a third reading. On eve-of-election polls, Orbit would have misplaced 14 seats in 2023 and 10 in November 2019.

Why trust it

Tested on past elections before going live.

Using eve-of-election polls, this method would have misplaced 12 of 350 seats in 2023 and 14 in November 2019. The real result landed inside our ranges 92 times out of 100.

In the Clacton by-election (U.K., August 13, 2026) we projected Nigel Farage at 62.6%: he won 63.3%, with Count Binface second, as forecast.

We were among the first models to flag that Texas could tip toward the Democrats.

Before the 2026 international football tournament, our model had Spain as title favourite (1st of 48 teams). Spain won the final.

    All 350 seats projected province by province, with the dates a snap election could fall on.

  • Housing tracker

    How housing became Spain’s top worry, and which party voters trust on it.

Methodology after the signal

How it works

A polling average, carried into every province and allocated under the real electoral law, thousands of times.

  • Published polls go through a Bayesian time-series model (BSTS), the same one behind all our forecasts, after correcting each pollster for its measured lean. Third-party re-estimates of CIS data are left out.
  • The national vote is carried into each province from the 2023 general election. New parties start from their latest result: SALF from the 2024 European election, Aliança Catalana and Adelante Andalucía from their regional elections.
  • Each simulation adds the real error of Spanish polls (measured 2015–2023), a regional effect and a provincial effect, then allocates seats under D'Hondt with the 3% threshold. 50,000 simulations.
  • Assumes polling day on Sunday, 29 November 2026. Seats per province are computed from INE population until the official BOE allocation is published.
