The next federal Senate election is scheduled to take place in Brazil on October 4, 2026, in which two-thirds of the Senate’s 81 seats will be contested. This market will resolve according to the political party that wins the greatest number of seats in the next Brazilian Senate election. Only seats contested in the next Brazilian Senate election will be considered. If the result of this election isn't known definitively by June 30, 2027, 11:59 PM ET, the market will resolve to "Other". This market will resolve based on the result of the election, as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the Brazilian government, specifically the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., www.tse.jus.br/eleicoes/resultados-eleicoes).Trader consensus heavily favors the Partido Liberal (PL) to secure the most seats in Brazil's October 4, 2026, Senate election, where 54 seats—two-thirds of the chamber—face renewal across 27 states and the Federal District. PL's lead stems from recent party-switching windows that elevated it to the largest current Senate bloc with 15 members, alongside strong state-level polling showing PL candidates like Carlos Bolsonaro and Carol de Toni topping surveys in Santa Catarina. Centrist MDB trails with competitive pre-candidates in 16 states, while PT and UNIÃO lag amid fragmented left-wing support. Tight presidential polls, including Datafolha's April 11 tie between Lula and Flávio Bolsonaro (PL), signal broader right-wing momentum influencing Senate projections.
