The numbers in detail

The Genial/Quaest survey, commissioned by brokerage Genial, tested a head-to-head matchup between the incumbent and Senator Flavio Bolsonaro, son of former President Jair Bolsonaro. Lula received 45% support compared to Flavio’s 37% in the simulated second round.

In a wider first-round scenario, Lula captured 40%, Flavio Bolsonaro 28%, followed by Goiás Governor Ronaldo Caiado at 4%, activist Renan Santos at 3%, and Minas Gerais Governor Romeu Zema at 2%. No other candidate tested in the survey reached above single digits.

For readers unfamiliar with Brazil’s electoral system, a candidate must win more than 50% of valid votes in the first round to avoid a runoff. When no one crosses that threshold, the top two finishers compete in a second round four weeks later.

That is why pollsters test both the multi-candidate first-round field and the likely two-person runoff scenarios side by side.

Approval, disapproval, and rejection

The same poll found President Lula’s job approval at 48%, with disapproval nearly identical at 47%. The one-point difference is within the margin of error, meaning the country is effectively split on his performance.

For Flavio Bolsonaro, a more serious warning sign lies in his rejection rate. Fifty-seven percent of respondents said they would not vote for him under any circumstance.

High rejection often acts as a hard ceiling in runoffs, making it difficult to capture swing voters.

Rejection is measured separately from disapproval. While disapproval reflects dissatisfaction with a politician’s current performance, rejection asks whether a voter would ever cast a ballot for that person.

A number above 50% is widely considered a structural obstacle because it means the candidate must convert people who have already ruled them out entirely.

Why this matters for investors and expats

The Genial/Quaest poll is produced for Genial, a Brazilian brokerage, which means financial markets monitor it closely. When the race tightens, investors reassess whether a market-friendly policy framework can endure after the October 2026 vote, often leading to short-term volatility in the Brazilian real and the Bovespa stock index.

For expatriates and foreign residents, the data points to a campaign that will likely dominate public debate for the next 15 months. Political stability, or the lack of it, directly influences utility prices, currency exchange rates, and the cost of living in major Brazilian cities where most foreigners settle.

The Bovespa, Brazil’s benchmark stock index, tends to rise when investors believe the next government will pursue fiscal discipline and fall when they fear looser spending. Because this poll is commissioned by a financial institution rather than a media outlet or party, traders treat it as a signal of where professional money managers are focusing their attention.

Broader campaign context

Flavio Bolsonaro, currently serving as a senator for Rio de Janeiro, is attempting to consolidate his father’s political base while presenting a more moderate image. Former First Lady Michelle Bolsonaro has also been mentioned in polling matchups, but the July 15 Genial/Quaest release focused on Flavio as the main opposition standard-bearer.

Lula, in turn, has been actively traveling the country to inaugurate infrastructure and housing projects, aiming to lift his approval ratings by highlighting economic delivery. The narrow gap between approval and disapproval suggests that economic sentiment—particularly inflation and employment—will be decisive in the 2026 contest.

The presence of multiple governors in the first-round field, even with low single-digit support, matters because Brazil’s federal structure gives state leaders significant local machinery. A candidate polling at 2% or 4% today could still influence the race by endorsing a frontrunner before the runoff, delivering regional votes that shift the final margin.

What to watch next

The next round of Genial/Quaest polling will reveal whether Lula’s 8-point runoff lead is widening or narrowing. A shift of even three or four points would change how both campaigns allocate resources across Brazil’s five regions.

Another open question is whether Flavio Bolsonaro can reduce his 57% rejection rate once the official campaign begins and he gains more television exposure. Historically, rejection numbers can soften when voters learn more about a candidate’s platform, but they can also harden if negative advertising dominates the airwaves.

On the economic front, any sustained rise in food prices or unemployment between now and the October vote would test whether Lula’s statistically tied approval rating can hold. Conversely, a period of falling inflation could allow him to open a clearer lead, reshaping the race from a competitive contest into a more comfortable re-election bid.
