Spain Polls Split Ahead of 29 November Vote
Spain votes on Sunday, 29 November 2026, and the polls disagree sharply on who is ahead. Most private pollsters favour the conservative People’s Party (PP), while the state-run CIS survey has the ruling Socialists (PSOE) well in front. Our Spain Election 2026 dossier tracks the race.
Prime Minister Pedro Sánchez called the early vote on 5 October. This came after Congress rejected two of his housing decrees on 2 October, with the PP, Vox and Junts voting against.

This story is part of our coverage of the Spain Election 2026. Dates, times and how to follow it are in our guide.
Polls Point in Opposite Directions
The CIS, a state body led by José Félix Tezanos, published its survey on 14 October. It is based on more than 5,000 interviews from 1 to 6 October and gives the PSOE an 11.8-point lead.
Private pollsters see the opposite. Sigma Dos for El Mundo, published on 19 October, has the PP at 31.5%, the PSOE at 25.3% and Vox at 19.5%. The PolitPro average on 23 October shows the PP at 31.8%, the PSOE at 26.4% and Vox at 18.9%.
What the Seat Projections Show
A GAD3 poll for ABC, published on 12 October from 1,077 interviews, projects 133 seats for the PP and 107 for the PSOE. Vox would win 65, so the PP and Vox together reach 198 seats, above the 176 needed.
Seats depend on provincial results, regional parties and turnout. National vote shares can therefore give very different seat counts.
What Prediction Markets Say
- Polymarket: Feijóo 82.0%, Sánchez 14.9%, Santiago Abascal of Vox 1.9% to be the next prime minister (about US$2.06 million traded).
- Kalshi (regulated in the US by the CFTC): Feijóo 79%, Sánchez 20%, Abascal 3%.
- Stand: 22 October 2026, 8:30 pm ET (2:30 am in Madrid). These are bets, not polls.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
What It Means for US Readers
A PP-led government backed by Vox would move Spain to the right. The split between the CIS and private polls echoes US arguments over poll reliability.
Traders currently see the opposition as the favourite despite the CIS result. They could be wrong, as bets are not votes.
What Is Not Known
We have not confirmed polling-station hours or the full campaign calendar. Nobody knows yet whether the PP and Vox can reach 176 seats together, or whether the CIS gap will narrow.
