**Brazil’s October 4 first-round presidential election is expected to produce a runoff on October 25 between incumbent Luiz Inácio Lula da Silva of the Workers’ Party and Senator Flávio Bolsonaro of the Liberal Party.** Recent national polls from AtlasIntel, Quaest, Datafolha, and BTG/Nexus show Lula leading the first round at 39–45% while Flávio Bolsonaro trails at 34–43%, with minor candidates such as Augusto Cury and Renan Santos in single digits. Runoff simulations remain statistically tied (typically 42–47% each), reflecting deep polarization, voter fatigue with living costs, and high rejection rates for both frontrunners. A major corruption scandal tied to banker Daniel Vorcaro has affected both camps, while Supreme Court proceedings related to former president Jair Bolsonaro’s conviction continue to energize the right. The final pre-election Globo debate on October 1 and any late shifts in turnout or undecided voters could influence first-round margins, but current data point to the same two candidates advancing.
