N2 - This study traces how Ecuadorian news outlets framed the 2025 general elections on social platforms. We analysed 8174 posts from 48 media accounts on Facebook, Instagram, TikTok and X (1 Jan-29 Jun 2025). Spanish texts were cleaned, embedded with a RoBERTa model, reduced via UMAP and clustered with BERTopic-HDBSCAN. Thirty-one topics emerged (mean coherence C-v=0.50; diversity =0.84); five hold 47.5% of the corpus and centre on Daniel Noboa and territorial voting patterns. Posting spikes on 9 Feb, 23 Mar and 13 Apr coincide with the first round, the presidential debate and the runoff, confirming an event-driven agenda. A document map shows dense central clusters for high-volume themes and scattered points for marginal narratives. Content production remains concentrated: three outlets generate nearly one-third of posts and Facebook carries over half the traffic, suggesting that social-platform affordances have not displaced traditional logics of centralisation and candidate-centric framing in Ecuadorian electoral journalism.
