What Prediction Markets Say
Polymarket, a crypto-based market, put Prime Minister Pedro Sánchez, the Socialist incumbent, at about 11% and Santiago Abascal, leader of the conservative Vox party, at about 1%. About US$2.9 million has been traded on the question, and these prices are bets rather than 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 the Latest Polls Show
SW Demoscopia, a Spanish polling firm, put the Spanish Socialist Workers’ Party (PSOE) at 31.0% and the PP at 28.5% in fieldwork from 26 October to 5 November. It projected 127 seats for the PSOE, 116 for the PP and 63 for Vox.
Celeste-Tel, polling for the radio network Onda Cero from 29 October to 3 November, reached the opposite result. It had the PP at 31.8%, the PSOE at 25.7% and Vox at 19.2%.
PolitPro, a poll aggregator, put the PP at 29.8%, the PSOE at 26.0% and Vox at 18.8% on 6 November. Its projection gives the PP 128 seats, the PSOE 112, Vox 81 and the Broad Front, a new left-wing alliance led by former Barcelona mayor Ada Colau, 29 seats, so no single party reaches the 176 needed for a majority.
The state-run Center for Sociological Research (CIS) showed the widest Socialist lead, at 34.0% to 22.2% for the PP in fieldwork from 1 to 6 October. We found no November CIS poll.

The Calendar Ahead
Spaniards vote on Sunday 29 November, after Sánchez called the election on 5 October. Congress had rejected two housing decrees on 2 October, with the PP, Vox and Junts, a Catalan party, voting against them.
Both Sánchez and Feijóo have accepted a one-on-one television debate on Monday 16 November, hosted by the private broadcaster Mediaset. No start time has been confirmed.
The new Congress meets on 23 December, and a prime minister is chosen only after that. The official campaign runs from 13 to 27 November.
Campaign Themes Take Shape
Sánchez launched his pre-campaign in Dos Hermanas, near Seville, on 10 October with housing as the central theme, before a crowd his Socialists count at more than 5,000. Feijóo has said the vote is a choice between four more years of the present situation and a chance for change.
Madrid Mayor José Luis Martínez-Almeida, a PP politician, warned that the campaign would be “dirty”, blaming the left. Isabel Díaz Ayuso, the PP president of the Madrid region, told people not to vote by post, while Feijóo’s spokesman Borja Sémper urged Spaniards to vote either in person or by post.
What It Means for US Readers
A close, fragmented result would leave the choice of prime minister to talks among parties after the new Congress meets on 23 December. That timetable is why a name may not be settled in the days after the 29 November vote.
A lasting government matters to investors holding Spanish bonds and shares. Market prices can move fast and should be read next to the polls.
What Is Not Known
The polls disagree sharply. SW Demoscopia and the state-run CIS have the Socialists ahead, while Celeste-Tel and GAD3 put the PP in front, and we cannot say which will prove closer to the result.
It is unclear whether the PP and Vox together can reach 176 seats. A GAD3 poll for the newspaper ABC, reported on 12 October, projected about 198 seats for the two parties combined, while SW Demoscopia’s figures leave them short.
The start time and final format of the 16 November debate have not been confirmed. Atresmedia, a private broadcaster, has proposed a four-way debate on 26 November, and the parties disagree on which channel should host it.
