As part of the ninth round of the Nexus/BTG Pactual study, the poll was conducted via telephone interviews from August 7 to 9 with 2,001 voters across the South American giant’s 27 federal units.
It has a margin of error of two percentage points and a confidence level of 95 percent; it is registered with the Superior Electoral Court (TSE) under number BR-08428/2026.
In a potential runoff between Lula and Flávio Bolsonaro, the president secures 47 percent compared to the senator’s 44 percent.
The three-point difference falls within the margin of error, resulting in a statistical tie between the two, according to media outlets such as the *Brasil 247* portal.
Lula also numerically outperforms other opponents included in the runoff simulations; the second round is scheduled for October 25, three weeks after the first round.
