Flavio Bolsonaro maintains a commanding lead in trader pricing for first place in the Federal District first round, driven by consistent pre-election polling showing him ahead of incumbent Luiz Inácio Lula da Silva by double-digit margins in valid votes. Surveys from Datafolha, Quaest, AtlasIntel, and Real Time in September and early October placed the PL senator at 40-52% support among DF voters, reflecting strong conservative preferences in the capital region, high government disapproval ratings, and momentum from the broader right-wing surge. Other candidates remained fragmented below 8%. With the October 4 vote complete, scenarios that could still alter the outcome include delayed final tabulation, legal challenges to results, or unusually high invalid ballots, though historical patterns and the scale of the lead make such shifts improbable.
