AtlasIntel 2026 Poll Shows Lula and Flávio Tied

AtlasIntel released on Saturday, the eve of the first round of voting, a poll with the intentions of voting for President of the Republic in the 2026 elections. The survey, contracted by the institute itself, heard 4,945 people between September 27 and October 2. The margin of error is 1 percentage point, with a confidence level of 95%.

In the first round scenario, President Luiz Inácio Lula da Silva (PT) leads with 47% of the voting intentions, followed by Flávio Bolsonaro (PL) with 44.1%. The result considers the votes valid, excluding the white ones, null and undecided. The difference between the two candidates is 2.9 percentage points, above the margin of error.

Technical tie in the second round

In the second round simulation, Lula is at 50.1% and Flavio at 49.9%, both tied within the margin of error of one percentage point. This scenario indicates a fierce dispute, in which any of the candidates can come out victorious. The survey considered the votes valid, excluding blank, null and undecided.

The proximity of the numbers reflects a divided electorate, with trends that may change until voting day. The narrow margin of error reinforces the need for caution in the interpretation of the results. The source did not detail the regional distribution or demographic profile of the interviewees.

Methodology and electoral registration

The survey was conducted by AtlasIntel with 4,945 respondents, between September 27 and October 2, 2026. The survey was contracted by the institute itself, with no external client identified. The confidence level is 95%, and the margin of error is 1 percentage point for more or less.

The registration in the Superior Electoral Court (TSE) was made under the number BR-00999/2026. The methodology used was not detailed in the information disclosed, but the institute is known for conducting online interviews. The People’s Gazette has published for years all the polls of intention to vote conducted by the main public opinion institutes of the country.

How to interpret electoral polls

Voting intention surveys make a reading for the time being, based on representative samples of the population. Interview methods, composition and sample number and even the way a question is asked are factors that can influence the outcome. Therefore, it is important to keep an eye on the methodologies information found at the end of the Gazeta do Povo articles on election polls.

In the case of AtlasIntel, the sample of 4,945 interviewees is considered robust for national estimates. The margin of error of 1 percentage point is relatively low, which increases the accuracy of the percentages. Still, the results should be seen as a portrait of the moment, not as a definitive prediction.

The Context of the Presidential Dispute

The first-round scenario shows Lula ahead, but with a narrow advantage over Flávio Bolsonaro. The difference of 2.9 percentage points is above the margin of error, which suggests a real but fragile leadership. In the second round, the technical tie indicates that the election can be decided by details, such as the mobilization of undecided and the transfer of votes of smaller candidates.

The survey does not provide information about rejection, government evaluation, or intention to vote for other positions. The source did not detail whether there were questions about scenarios with other candidates or about the certainty of the vote. These elements can be crucial to understanding the dynamics of the dispute.

The Importance of Election Day

Disclosure on the eve of the first round is strategic, as it can influence undecided voters and reinforce trends. Research published during this period usually has a great repercussion in the press and on social networks. However, it is essential that the voter seeks complete information, including the methodology and history of the institute.

AtlasIntel has conducted regular surveys on the 2026 elections, and its results are closely followed by political analysts. The current research reinforces the polarization between PT and PL, with the two main candidates concentrating the vast majority of voting intentions. The source did not detail the percentage of blank, null and undecided votes in the stimulated scenario.

Next steps and coverage

With the vote scheduled for this Sunday (4), voters must attend the polls and exercise the right to vote. The Boca no Trombone team will continue to follow the count and bring real-time updates. For more information on the elections in 2026, please visit other topics on the portal.
