April 28, 2026

1. Prediction market

Polymarket closed April 28 with the smallest gap between Lula and Flávio Bolsonaro of the cycle. Lula rose from 35.5% to 38.50% (+3.0pp) — largest daily gain recorded. Flávio fell from 40.30% to 38.75% (-1.55pp), giving back the 40% peak achieved yesterday. The gap closed from 4.8pp Flávio to 0.25pp Flávio — first time in the cycle the market priced a technical tie between the two favorites.

The "second place in 1º turno" market registered the largest isolated rise of the cycle for Lula: 17% → 25.5% (+8.5pp). Flávio retreated from 66.5% to 63.5% (-3pp), maintaining dominance but with clear erosion. Fernando Haddad gave back almost all of yesterday's recovery (5.8% → 2.95%, -2.85pp) — extreme volatility continues. Forbes Brasil recorded that "Flávio appears numerically ahead of Lula in a possible runoff" (14:48), while CNN Brasil (18:38) and Pleno.News (11:50) consolidated the reading that "Lula ties with Flávio, Jair, and Zema in the runoff."

The third way had a day of redistribution. Romeu Zema fell in the presidential from 9.45% to 7.90% (-1.55pp) — below 8% for the first time in the recent cycle, losing what had been read as third-way leadership. In the "third place" market, Zema retreated from 40.5% to 39.5% (-1pp) — still at the top, but eroded. Renan Santos rose from 5.5% to 6.35% in the presidential (+0.85pp); the "third place" went to 27.5% (+1pp). Carlos "Ratinho Jr." Massa surged in the third place from 1.05% to 7.10% (+6.05pp) — the largest isolated rise of the cycle in this segment. Eduardo Leite appeared as a new relevant name in the third place at 3.35%. Caiado gave back to 22.5% (-1.5pp).

STF justice impeachment rose from 11% to 14% (+3pp) — giving back part of yesterday's historic drop (-5pp). 14-day trajectory: 13.5% → 11% → 12% → 12.5% → 12.5% → 14% → 14% → 14% → 15.5% → 15% → 15% → 16% → 11% → 14%. In the Senate, PL recovered from 81.5% to 85.5% (+4pp), and União Brasil surged from 6.7% to 11.25% (+4.55pp). PSD retreated slightly to 6.40%, MDB rose to 3.95%. PT stable at 2.70%.

In inflation expectations, the market priced the largest dispersion of the cycle: five bands with probability above 30% (5.50-5.99%, 7%+, 5.00-5.49%, 4.50-4.99%, 6.00-6.49%, 3.00-3.49%). The central scenario remains around 5.0-6.0%, but the probability of extremes (>7% or <3%) remains open.

2. What the institutes registered

The TSE database reached 204 polls indexed after the 12:00 UTC refresh. The day delivered the largest sample of the cycle recorded: AtlasIntel n=5,000 + 2 Quaest + 3 others = approximately 10,700 respondents.

The anchor poll was AtlasIntel/Bloomberg, published at 10:00 by nine outlets: InfoMoney, Gazeta do Povo, CartaCapital, VEJA, CNN Brasil, Poder360, Pleno.News, Forbes Brasil, Valor Econômico. Results: 1º turno Lula 46.6% × Flávio 39.7% — Lula leads by 6.9pp. 2º turno (Valor Econômico, 19:16): Flávio 47.8% × Lula 47.5% — empate técnico, with Flávio numerically ahead. Lula's approval rose to 46.6-46.8% according to O Cafezinho, Diário do Estado, and JOTA. Rejection stood at 51.3-52.5% — variation between outlets (Metrópoles, AL 102, InfoMoney, SpaceMoney). Blog do BG recorded rejection of 75% among young people. Flávio's rejection: 49.8% (Pleno.News).

The Quaest/Genial published a robust state package. In Minas Gerais, Cleitinho leads all scenarios of 1º turno and 2º turno against Kalil, Pacheco, and Simões, with Kalil in 5th place — simultaneous coverage by Folha de S.Paulo, Gazeta do Povo, CNN Brasil, and O Globo. In Pernambuco, G1 published Quaest 2º turno: João Campos 46% × Raquel Lyra 38%. Next publications registered at the TSE: 4 Quaest on Apr 30, F. Façanha on May 1, M B Barros on May 2.

As a methodological observation: O Tempo recorded at 00:21 that "even off the air in Brazil, Polymarket moved US$ 60 million in bets on the October election" — the relative liquidity of the market remains robust despite the regulatory blockade imposed on April 24.

3. What the press covered

The day's agenda was crossed by four blocks: Lula's recovery in the polls, the PT campaign strategy, Renan Santos breaking silence, and the advance of the Vorcaro investigation.

Metrópoles (10:00) covered the PT's official strategy for 2026: "how Lula will portray Flávio in the campaign — corruption and national surrender." It is the first time the petista offensive narrative against the PL candidate appears structured publicly. JOTA recorded at 13:11 that "Lula's approval rises, but the dispute remains open." In parallel, G1 (12:32) published that Flávio Bolsonaro acts to have evangelicals reject Messias — active movement against the name nominated by the government to the STF, with strategic religious base. BBC (07:38) reported that Renan Santos broke 11 days of silence with the phrase: "I am the right's candidate" — direct dispute over the votes Flávio had been consolidating.

On the conservative side, Correio Braziliense (19:13) covered Gilberto Kassab stating that "the election is not defined between Lula and Flávio" — sign that the PSD may reopen alliance negotiations. The same Kassab appeared in Folha de S.Paulo (22:07) criticizing Lula's administration — PSD inside the government criticizes publicly. Estadão (18:57 and 23:54) covered Ciro Nogueira stating that the election "will be decided by margin of error" and that he "sees no room for a third way" — analysis that amplifies the Lula × Flávio binary.

In the São Paulo Senate, InfoMoney (14:56), Poder360 (02:30), and Revista Oeste recorded that Podemos supports Tarcísio but launches Palumbo and Rufino as its own to the Senate — right expanding legislative organization in SP.

In the Judiciary, SBT News (14:43) recorded that the PF accessed new Vorcaro phones and postponed the delivery of the report on officials with privileged forum cited — investigation deepens. In parallel, SBT News (15:47) reported that the office of Alexandre de Moraes's family sued Alessandro Vieira for a statement about PCC — STF on the public offensive.

4. Divergences of the day

In summary

1. Polymarket priced a technical tie between Lula and Flávio for the first time in the cycle (38.50% × 38.75%, gap 0.25pp), closing yesterday's 4.8pp in 24 hours. AtlasIntel/Bloomberg n=5,000 — second consecutive major national poll — registered Lula leading 1º turno by 6.9pp (46.6% × 39.7%) and an empate técnico in the 2º (47.5% × 47.8%). Market and poll converged partially: the market moved in the direction of the poll (+3.0pp for Lula), but maintains pricing open — has not sealed the bet.
2. The "second place in 1º turno" market registered the largest isolated rise of the cycle for Lula (17% → 25.5%, +8.5pp), while Massa "Ratinho Jr." surged in the third place (1.05% → 7.10%, +6.05pp) — a signal that the market is redistributing expectations to sub-third-way outsiders. In parallel, Zema fell below 8% (-1.55pp) and lost the reading of consolidated third-way leadership.
3. It is the seventh and final day of the AFOS Hoje pilot — seven syntheses published in seven consecutive days, covering from April 22 (3 polls, ~2,500 respondents) to April 28 (AtlasIntel n=5,000 + Quaest MG/PE, ~10,700 respondents). The final GO/NO-GO decision is scheduled for tonight, per the pilot's schedule. The continuity of the feature in production depends on this decision.
