Opinion polling for the 2025 Czech parliamentary election

Polling industry

Political polling in Czechia has, compared to the European mean, a medium to high level of polling error. Pollsters with low Absolute Total Raw Error in the past elections include Phoenix, STEM, and SANEP. Higher Absolute Total Raw Error occurred for Ipsos, Kantar, and Median.

The pollster Phoenix has reportedly links to has people close to the party Trikolora and/or former president Václav Klaus. SANEP's Jan Fulín (managing director) received major financial contributions from chairman of the party SPD, Tomio Okamura. ^[1] Sanep's polls before the election showed SPD consistently stronger than other pollsters.

Graphical summary

Local regression graph of polls conducted since the 2021 election by party

Polls

The party in first has its cell shaded in the party's colour. Polling figures which are in bold indicate the relevant party is above the threshold to gain representation. Single party lists need to pass a 5% threshold, two-party coalitions need to pass an 8% threshold and three or more-party coalitions need to pass an 11% threshold.

From January 2025 until the election, STEM began to post weekly polls for CNN Prima News, which were a rolling sample including over 500 respondents each week, which incorporated the last 3 waves of respondents. ^[2]

Polls including SPOLU

The polls in this section took place after the Pirates and Mayors alliance, which ran in the 2021 election, ruled out working together at the next election. ^[11] They show the polls if the ODS, KDU-ČSL and TOP 09 join to continue the SPOLU alliance that contested the 2021 election and came in first place, over ANO. These polls took place prior to the announcement SPOLU would be recreated in the next election.
