Another day without national polling and the market reversed yesterday's gains: Flávio retreated to 26.50% and the gap over Lula (60.50%) widened again to +34.00pp, in a presidential race whose total accumulated volume reaches USD 113.7M. Renan interrupted the convergence and rose to 8.30%. Outside the ballot box, the day belonged to Moraes, who denied Milei's visit to Bolsonaro.
1. Prediction market
The presidential market, whose total accumulated volume sums to USD 113.7M, spent the day reversing yesterday's movement. Flávio Bolsonaro fell 0.55pp to 26.50% (USD 7.5M), undoing the 1.60pp spike from yesterday, while Lula remained flat at 60.50% (USD 7.4M). With this, the gap between the two widened again, from +33.45pp to +34.00pp, due to the opponent's decline, not Lula's rise. Without new national polling and without ballot events, the back-and-forth in Flávio's price is market momentum, AFOS adjusting conviction, not reacting to fact.
In the third way, Renan Santos halted the correction he had been making and rose 0.45pp to 8.30% (USD 8.2M), after three sessions declining from 10.15% toward the 6% that PoderData measured. Michelle Bolsonaro fell back to 1.80% (USD 9.1M) and Ronaldo Caiado rose to 1.40% (USD 5.0M), adjustments for residual names without ballot backing.
In the sub-markets, the 2nd place in the 1º turno tracked the presidential: Flávio ceded to 81.50%, followed by Renan (10.7%). In 3rd place, Renan leads with 68.50% and Caiado advanced to 16.50%. In the Senate by seats, PL remains comfortable at 85.50% (USD 250 thousand), ahead of MDB (13.8%).
The impeachment of STF minister market rose slightly, to 3.60% (USD 84 thousand), and remains near the floor, in the noise range. A methodological note is warranted: the volume of this book is orders of magnitude below the USD 7.4M of the presidential, so the signal is weak. On 2026 inflation, the modal range of the market is 5.00% to 5.49%, at 39.60%, in line with the official Finance projection (5.1%), above the Central Bank target.
2. What the institutes registered
It was the second consecutive day without new national polling. The latest with national scope remain the Genial/Quaest of July 15 (n=2,004, reliability 5) and PoderData/Aya from July 16 (n=2,400). In both, Lula is identical: 40% in the 1º turno and 45% in the 2º turno. The entire disagreement is in Flávio, measured between 28% (Quaest) and 34% (PoderData) in the 1º turno, six points of difference that characterize house effect, not electorate movement.
At the state level, the Quaest of Espírito Santo gave Flávio at 42% against 36% for Lula, a local portrait that does not enter the national panel's scope. State-level polling remains outside the national dashboard by scope rule.

3. Press coverage
The political fact of the day was institutional. Alexandre de Moraes, presiding over the STF during recess, denied the request for Javier Milei to visit Jair Bolsonaro in house arrest. The visit was scheduled for July 25, when the Argentine president would come to Brazil for the PL convention and the launch of Flávio's candidacy. In a sole decision, Moraes blocked visits with political-electoral objectives until the end of the elections and suspended general visits for 30 days, allowing only lawyers, doctors, and physiotherapists. The decision came after Flávio released a handwritten letter from Bolsonaro to the Brazilian people, and the Bolsonarism classified the act as silencing.
In the opposition camp, Flávio Bolsonaro had day of scheduled testimony and new response to the tariff dispute with the US, while the PT intensified attacks on him on social media. In the Master case, the PF opened an international front: activated Interpol to track Daniel Vorcaro's assets in the US and Europe via the Silver Notice mechanism, in a development of Operation Compliance Zero.
On the government side, Folha de S.Paulo pointed to Lula as the week's winner among the three branches of government, but his agenda remains stalled: the Senate left for recess without voting on priorities, projects remained in limbo and four provisional measures lapsed in July due to lack of voting.
4. Day's Divergences
Market × polling (Renan): Renan Santos is worth 8.30% in the winner's market, against 6% in the best poll he has received (PoderData July 16) and 3% in Quaest (July 15, the most reliable one). It is the largest relative distortion on the panel, and the two polling firms still disagree on who leads the third way. Without new polling, the price adjusted itself today, rising.
Probability × vote (Flávio): the market gives 26.50% probability of Flávio winning the election, a number that measures chance of winning, not voting intention. In the polls he appears between 28% and 34% in the 1º turno. These are different measures, and the gap between them is the signal that AFOS Analytics tracks, not a polling error.
Market × narrative (STF): despite Moraes' decision denying Milei's visit dominating the news, the STF minister impeachment market remained at 3.60%, near the floor. Real money prices institutional friction, not rupture.
In summary
- The market reversed yesterday's gains: Flávio fell to 26.50% (↓0.55pp) and the gap over Lula (60.50%) reopened to +34.00pp, without polling trigger, in a presidential market of US$ 113.7M.
- Another day without national polling (next ones on July 21 and 22), and the day's fact was Moraes denying Milei's visit to Bolsonaro, with PF still activating Interpol after Vorcaro's assets.
- Renan remains the largest divergence on the panel: 8.30% in the market against 6% in the best poll and 3% in Quaest, without new polling to arbitrate.-
