Recent polling from late August 2026 shows a tight contest for the two Rio Grande do Sul Senate seats, with Marcel Van Hattem (Novo), Manuela D'Ávila (PSOL), Ubiratã Sanderson (PL), Paulo Pimenta (PT), and Germano Rigotto (MDB) in technical ties within margins of error on consolidated first- and second-choice votes. High undecided rates (often 35-40%) and the dual-vote system sustain volatility around second place, as voters split preferences across ideological lines and emerging alliances. Candidate registrations are finalized ahead of October balloting, with limited late momentum shifts reported in the most recent surveys. Trader pricing reflects this uncertainty, where any narrowing of undecideds or targeted campaign events in the coming weeks could reorder the field.
