Recent August 2026 polls, including Quaest and Datafolha, show a technical tie among top contenders for São Paulo’s two Senate seats, with Guilherme Derrite (PP), Marina Silva (Rede), Simone Tebet (PSB), and André do Prado (PL) clustered near the top and high undecided or blank/null shares exceeding 40 percent. Marina and Tebet were confirmed in June as part of the PT-PSB coalition backing Fernando Haddad for governor, while Derrite and Prado represent the center-right alignment around incumbent Governor Tarcísio de Freitas. This fragmented field, combined with low voter definition and the dual-vote system, sustains tight probabilities for second place in trader assessments. Further campaign momentum, alliance adjustments, or shifts among undecided voters before the October 4 first round could widen gaps.
