**PL leads trader consensus for the largest share of seats in Brazil’s 513-member Chamber of Deputies, followed closely by the UPB federation, with all other parties priced near zero.** PL’s advantage reflects its strong state-level organization, alignment with right-wing voter mobilization behind presidential candidate Flávio Bolsonaro, and proven performance in proportional representation contests. UPB—formed by the merger of União Brasil and Progressistas—draws on its sizable existing bench, extensive mayoral and gubernatorial networks, and center-right positioning that appeals to centrist voters and tactical alliances. The October 4 vote occurs amid a tight presidential race that has sharpened partisan turnout expectations, while party federations and state-level coalitions shape seat allocation under Brazil’s open-list system. No major shifts in legislative-specific polling have emerged since campaigns officially began in mid-August, leaving current pricing anchored in these structural and alliance dynamics.

This market will resolve according to the political party or electoral federation that holds the greatest number of seats in the next Brazilian Chamber of Deputies (Câmara dos Deputados) as a result of the next Brazilian Chamber of Deputies election.
In the event of a tie between multiple entities for the most seats held, this market will resolve in favor of the entity whose listed abbreviation appears first in alphabetical order.
This market's resolution will be based solely on the number of seats held by the named party or electoral federation in the Brazilian Chamber of Deputies as a result of the next Brazilian Chamber of Deputies election, not by any coalition it may be a part of.
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) or the Brazilian Chamber of Deputies (https://www.camara.leg.br/).**PL leads trader consensus for the largest share of seats in Brazil’s 513-member Chamber of Deputies, followed closely by the UPB federation, with all other parties priced near zero.**
