**PL has secured a commanding lead in Brazil’s October 4, 2026, Chamber of Deputies elections, projected to win approximately 121 seats—the largest single-party bloc since the 1988 Constitution.** This outcome stems from robust right-wing performance across states, including gains in key regions like Rio de Janeiro, Rio Grande do Sul, and Santa Catarina, alongside the coattails effect from Flávio Bolsonaro’s first-round presidential showing. Multiple family members also won legislative seats, reinforcing PL’s organizational strength and voter consolidation among conservative, evangelical, and agribusiness-aligned blocs. Partial tallies from over 99% of precincts confirm PL far ahead of the PT-led federation and center-right alliances such as União Progressista. While seat shifts from party switches or runoffs remain possible before the new Congress convenes in February 2027, current verified results leave little room for another party to overtake PL’s total. Trader consensus reflects this decisive legislative result rather than presidential uncertainties.
