Recent August 2026 polls from Quaest and Real Time Big Data show five leading candidates—Manuela D'Ávila (PSOL), Marcel Van Hattem (Novo), Paulo Pimenta (PT), Ubiratan Sanderson (PL), and Germano Rigotto (MDB)—statistically tied for the two Senate seats, with results consolidated across first- and second-choice votes falling within margins of error of 2–3 points. Large blocs of undecided voters (30–40%) and the dual-vote format sustain the tight contest, as support fragments across party alliances tied to the competitive gubernatorial race. A recent candidate debate highlighted policy differences on gender-based violence, pensions, and anti-corruption measures without shifting the polling equilibrium. Trader consensus on Polymarket reflects this balance, with separation likely to emerge from further polling shifts, endorsements, turnout patterns in key regions, or late campaign developments before the October election.
