For the first time in the cycle, Renan Santos (38%) overtook Romeu Zema (37%) on Polymarket's 'third place' market — a historic inversion. Zema, who had led that market since mid-April, also fell in the presidential race to 4.70% (-2.15pp) — below 5% for the first time in the recent cycle. The fallout from the Senate's rejection of Jorge Messias on April 29 was amplified by 8 outlets carrying the phrase 'lack of governability' (Flávio Bolsonaro), and Congress overrode the presidential veto on the reduction of Jair Bolsonaro's sentence — fourth legislative defeat in 48 hours. The STF justice impeachment market rose to 15.50%.

1. Prediction market
Polymarket closed April 30 with stability in the presidential race and total reorganization in the third way. Lula held at 37.50% (stable), and Flávio Bolsonaro retreated marginally to 43.00% (-0.1pp), preserving the cycle high. The gap between the two stood at 5.5pp in favor of Flávio — virtually identical to the 5.6pp of April 29. After the earthquake of the Messias rejection, the presidential race entered a digestion phase.
The third way had a historic inversion. Renan Santos surged in the "third place" market from 33.50% to 38% (+4.5pp) and overtook Romeu Zema (37%, -2pp) for the first time in the cycle. Zema had been leading that market since mid-April with margin (reached 40.5% on Apr 28); the inversion is structural, not noise. In the presidential, Zema plunged from 6.85% to 4.70% (-2.15pp) — below 5% for the first time in the recent cycle, definitively losing the reading of strength as a consolidated third way. Renan in the presidential held stable at 5.65% (-0.1pp) — a wide discrepancy between the "third place" (38%) and the presidential (5.65%) suggests the market prices Renan as "consolidated third place" but not as "competitive presidential candidate".
Other moves in the "third place": Caiado recovered to 21.50% (+2pp, benefited by Zema's collapse); Tarcísio doubled to 1.65% (was 0.70% — center-right governing outsider emerges); Eduardo Bolsonaro plunged to 0.30% (was 1.50%); and Carlos "Ratinho Jr." Massa disappeared from the market (was at 0.65% on Apr 29, at 7.10% at the peak on Apr 28).
In the "second place in 1º turno" market, Lula partially recovered to 21.50% (+2.5pp, up from 19% on Apr 29) — the market began to give back the drop from rejection day. Flávio rose to 66% (+1pp). Haddad gave back to 4.35% (-0.65pp), reversing part of the recovery on Apr 29.
The STF justice impeachment market rose from 15% to 15.50% (+0.5pp) — near the cycle peak (16%, recorded on Apr 24). In 72 hours, this market rose 4.5pp. 16-day trajectory: 13.5% → 11% → 12% → 12.5% → 12.5% → 14% → 14% → 14% → 15.5% → 15% → 15% → 16% → 11% → 14% → 15% → 15.50%. The continued rise coincides with Folha's report (14:52) that "the Messias veto opens space for an STF with Bolsonaro appointees if Flávio wins".
In the Senate, the reorganization was massive: PL gave back from 76% to 74% (-2pp), and five parties plunged simultaneously — União Brasil to 11.45% (-4.75pp), PSD to 2.95% (-2.65pp), Republicanos to 1.00% (-8.25pp), PSB to 0.85% (-9pp), and Novo to 0.25% (-12.4pp, near-total collapse of Zema's party in the market). PT held stable at 2.65%; MDB at 2.30%. In inflation expectations, the market consolidated in 5.00-5.49% (39.85%, +2.6pp) — the only band above 30%. The extreme tails plunged: 7%+ fell to 3.05% (-14.15pp); 6.00-6.49% fell to 5.35% (-13.35pp); 3.00-3.49% fell to 2.95% (-10.05pp).
2. What the institutes registered
The TSE database held at 209 polls indexed (40 in the past 15 days) — no new insertions in this refresh. The reference poll remains the AtlasIntel/Bloomberg of Apr 28 (n=5,000): 1º turno Lula 46.6% × Flávio 39.7%; 2º turno Flávio 47.8% × Lula 47.5% (technical tie).
The Quaest/Genial published a state-level package today. In Bahia, G1 recorded at 03:01 that 47% want a governor allied with Lula, 32% prefer an independent, and 16% want one allied with Bolsonaro — the government's northeastern base maintained. In Rio Grande do Sul, G1 (11:00) published Juliana Brizola and Luciano Zucco in technical tie in the gubernatorial race. In Goiás, Daniel Vilela (MDB) leads with 33% in the first round — center-aligned ally with consolidated regional base.
The next batch concentrates in May: F. Façanha on May 1 (n=1,006), M B Barros on May 2, A.F. Barbosa + 100 Cidades + M B Barros on May 3 (~3,584 respondents), SETA + PERCENT + 100 Cidades on May 4 (~3,950), and Real Time Big Data on May 5 (n=2,000, confidence 0.9 — the highest credibility of the week). Calendar Apr 30-May 5: approximately 16,000 respondents in six days before the public launch (rescheduled on May 5 to Tuesday, May 12, 2026).
3. What the press covered
The day's agenda was crossed by three blocks: amplified Messias fallout, fourth opposition legislative victory in 48 hours, and institutional reorganization.
The phrase "lack of governability of Lula" attributed to Flávio Bolsonaro was amplified simultaneously by eight outlets: UOL Notícias, ND Mais, BNews Natal, Times Brasil/CNBC, Repórter Maceió, Varela Net, Portal Correio, and Gazeta do Povo. Gazeta do Povo published an analysis stating that "elections, Lula's declining support, and STF in crisis explain the Senate's rejection of Messias". BNews and Tribuna do Sertão reported the phrase "the Lula government is over". JOTA (18:15) covered that "the opposition has electoral advantage in the Senate, with the Chamber hostile to Lula and the STF".
Folha de S.Paulo (14:52) registered the direct institutional implication: "the Messias veto opens space for an STF with Bolsonaro appointees if Flávio wins". In parallel, BBC Brasil (18:51) reported that Congress overrode the presidential veto that opened the path for the reduction of Jair Bolsonaro's sentence — the fourth opposition legislative victory in 48 hours (Messias rejection + CPI Master archiving + sentence reduction + now veto override). Folha confirmed that "Alcolumbre is to bury the CPI do Master in an agreement with the opposition in exchange for the reduction of Bolsonaro's sentence".
On the government side, Diário do Estado recorded that "Lula is analyzing retaliations after the Messias rejection". Agora RN reported that the president traveled to Rio Grande do Norte to expand regional advantage in the Northeast — a counter-attack in an electorally favorable base. Tribuna do Sertão recorded that "Lula will not appoint a new STF nominee" (a posture of not escalating the conflict), and SBT News covered that "the PT defends maintaining dialogue with Alcolumbre" — a conciliatory posture despite the defeats. G1 reported that the Federal Police is analyzing a plea deal from a former INSS prosecutor about Banco Master.
As a positive institutional note, O TEMPO (14:35) recorded that the 2026 elections will have a record number of women as presidents of Regional Electoral Tribunals (TRE). G1 (14:38) reported that the TSE determined a new election in Roraima following the cassation of Governor Edilson Damião.
4. Divergences of the day
Amplified fallout × stable presidential Polymarket. Eight outlets amplified the phrase "lack of Lula governability" and the BBC reported the fourth legislative defeat of the government in 48 hours. On the same day, the presidential Polymarket closed with Lula stable (37.50%) and Flávio retreating 0.1pp (43.00%) — a gap identical to that of Apr 29. The "government over" narrative did not translate into additional market movement. Possible readings: (a) the Apr 29 earthquake had already priced in the rejection; (b) the market needs a new event, not amplification of an existing one; (c) the 5.5pp Flávio gap is the provisional ceiling given current fundamentals.
"Third place" market × presidential Renan. Renan surged to 38% in "third place" and overtook Zema for the first time in the cycle. But in the presidential, Renan held stable at 5.65% (-0.1pp). A discrepancy of 32 percentage points between the two markets suggests Polymarket prices Renan as "consolidated third" but not as "competitive presidential candidate". The space left by Zema (-2.15pp in the presidential) migrated mainly to Caiado in "third place" and to Tarcísio (who doubled from 0.70% to 1.65%), not to Renan in the presidential.
Inflation consolidates × politics reorganizes. On the same day the Senate shows extreme reorganization (five parties plunging simultaneously, PL giving back, União giving back) and the STF impeach rises to 15.50% (near the peak), the inflation market consolidated in 5.00-5.49% (39.85%, the only band above 30%), with extreme tails plunging — 7%+ fell 14.15pp, 6.00-6.49% fell 13.35pp, 3.00-3.49% fell 10.05pp. The reading: economic uncertainty decreased on the same day institutional uncertainty increased. The market treated institutional events as noise on the real economy, not as a macroeconomic shock.
In summary
- For the first time in the cycle, Renan Santos (38%) overtook Romeu Zema (37%) on Polymarket's "third place" — a historic inversion after Zema had led the market for two weeks. In the presidential, Zema plunged to 4.70% (-2.15pp), below 5% for the first time in the recent cycle. The reorganization of the third way was total: Caiado recovered to 21.50% in "third place"; Tarcísio doubled to 1.65%; Eduardo Bolsonaro plunged to 0.30%; Massa Ratinho disappeared.
- The fallout from the Messias rejection dominated the narrative: eight outlets amplified "lack of Lula governability"; Folha recorded that the veto opens space for an STF with Bolsonaro appointees if Flávio wins; the BBC reported the override of the presidential veto on the reduction of Jair Bolsonaro's sentence — fourth legislative defeat in 48 hours. The "STF impeach" market rose to 15.50%, near the cycle peak (16%, recorded on Apr 24).
- The Senate had extreme reorganization: PL gave back to 74% (-2pp), União to 11.45% (-4.75pp), and five parties plunged simultaneously — Republicanos -8.25pp, PSB -9pp, Novo -12.4pp (near-total collapse), PSD -2.65pp. Inflation consolidated in 5.00-5.49% (39.85%, the only band above 30%), with extreme tails plunging — a signal that economic uncertainty decreased on the same day institutional uncertainty increased.
