The Basque Government predicts a tie of 29 seats between PNV and Bildu while the PSOE and the PP would repeat the results of 2020. The two nationalist forces that advocate for a 'new Basque sovereign status' and demand the recognition of Euskadi as a nation would obtain 77% of the 75 seats in the Basque Parliament.

However, governance from 21-A will be in the hands of the PSE-EE which, with its 10 parliamentarians, rules out supporting Bildu.
