São Paulo's October 2026 Senate contest features two seats, creating intense competition for second place among a crowded field. Recent polls from Datafolha, Genial/Quaest, and Vox Brasil show Marina Silva and Simone Tebet, running on Fernando Haddad's gubernatorial ticket, holding narrow leads in vote intention, while Guilherme Derrite, André do Prado, and Ricardo Salles remain within striking distance in technical ties. The fragmented electorate, high undecided share, and dual-vote format sustain volatility, with no candidate consolidating a clear advantage. Late-campaign events such as debates, endorsements from state party leaders, or shifts in the parallel gubernatorial race could reorder preferences and separate contenders ahead of election day.
