Tarcísio de Freitas Eyes First-Round Victory in São Paulo Race

SÃO PAULO — Incumbent Governor Tarcísio de Freitas has emerged as the clear favorite to secure a first-round victory in São Paulo’s gubernatorial race, according to a major poll released on Saturday, October 3, 2026, on the eve of the vote. The final survey by polling firm Quaest shows the conservative governor commanding 60% of valid votes, putting him well above the majority threshold required to avoid a second-round runoff on October 25.

His main challenger, Fernando Haddad of the leftist Workers’ Party (PT), trails significantly at 36% of valid votes. The Quaest survey, commissioned by broadcaster TV Globo, interviewed 3,702 voters across the state of São Paulo between October 2 and October 3, carrying a margin of error of two percentage points. Valid votes exclude blank and null ballots, replicating the official methodology used by Brazil's electoral court, the Tribunal Superior Eleitoral (TSE), to declare a winner.

A dominant performance in São Paulo—Brazil’s most populous state and its undisputed economic engine—cements Tarcísio's position as a premier power broker on the national stage. São Paulo alone accounts for approximately one-third of the country's gross domestic product, making its governorship one of the most influential political offices in South America. Tarcísio, a former infrastructure minister under former right-wing President Jair Bolsonaro, has successfully cultivated a reputation as a pragmatic administrator while maintaining strong ties to the conservative base.

The lopsided polling figures represent a major setback for President Luiz Inácio Lula da Silva’s PT, which had hoped Haddad—a former federal finance minister and former mayor of São Paulo—could force a competitive second-round runoff. Instead, the race has highlighted the deep political polarization running through the state. While Lula joined Haddad for a final campaign rally on Avenida Paulista in the state capital on Saturday, Tarcísio closed out his campaign alongside conservative Senator Flávio Bolsonaro in the state's industrial interior, demonstrating his strong appeal outside the metropolitan core.

The outcome of the São Paulo gubernatorial race is highly consequential for the broader trajectory of the brazil election cycle. A first-round victory would instantly position Tarcísio as a leading contender for the presidency in future cycles, offering a formidable, moderate-leaning conservative alternative to the PT. Voters will head to the ballot boxes on the official brazil election date of Sunday, October 4, with the first official brazil election results expected to trickle in within hours of polls closing at 5:00 p.m. local time.
