1. What the prediction market priced

In the Brazil Presidential Election market, Flávio Bolsonaro closed at 44.25% (↑0.30pp slight relative to May 3), extending the lead. Lula fell to 36.50% (↓1.0pp), fourth consecutive day of strong decline (was 38.50% on May 1, 37.50% on May 3). The gap between the two widened even further to +7.75pp, against +6.45pp at the previous close — largest gap since mid-April.

No clear triggering event on May 4 with sufficient strength to explain the magnitude of the movement. The technical reading is continuity of Lula's downward trajectory that began on May 1, now with a gap at an unprecedented level in the cycle. In the 2nd place market, Flávio retreated slightly to 66.50% (↓1.0pp) and Lula recovered to 19.50% (↑0.50pp slight) — small recoveries in the second-place market.

The most notable movement in the third way is Romeu Zema's recovery in the presidential race: 5.05% (↑1.30pp), reversing four consecutive days below 5% (was 3.75% on May 3). Renan Santos remains stable at 5.55% (↓0.10pp slight) in the presidential race. In the 3rd place market, there was strong reorganization with low liquidity: Zema ceded leadership to 38% (↓1.5pp), Renan returned to 31% (↓5pp, from 36%), while Caiado jumped to 19% (from 0.55%) and Flávio to 10.05% (from 0.4%). The 3rd place movement should be read with caution — the market has low 24h volume (US$4-90k per contract) and fluctuations of this magnitude are possible with few large orders.

Haddad stabilized after two days of strong decline: 3.05% (↑0.10pp slight, from 2.95%). Camilo Santana remains stable at 3.85%, maintaining fragmentation on the left (0.80pp ahead of Haddad). In the STF impeach market, the market returned to 13.00% (↓0.50pp), continuing the slight decline from 13.5% on May 3. In the Senate market, reverse reorganization from May 3 movement: PL slightly cedes to 86.00% (↓1.0pp); PSD recovers strongly to 5.85% (↑3.70pp, from 2.15%); MDB recovers strongly to 3.45% (↑2.20pp, from 1.25%); PSB jumps to 3.25% (↑2.50pp, from 0.75%); União Brasil returns to 4.35% (↓1.15pp); PT returns to 2.30% (↓1.0pp); Republicanos emerges at top with 1.35%. In 2026 inflation, band 6.00-6.49% jumps to 20.30% (↑4.15pp, from 16.15%) — continuation of the upward trajectory of the intermediate band.

2. What polling institutes registered

Three poll publications on May 4. Veritá Pernambuco (CNN Brasil, May 4 at 18:42) registers Lula 43.3% × Flávio 30.9% in the 1º turno, with Lula leading by 12.4pp; sample 2,010, TSE registration BR-04215/2026, but with important caveat: fieldwork was March 24-30, 2026, five weeks before publication. The poll is outdated data relative to Polymarket (which has daily flow) and the calendar of other more recent polls — readers should consider whether it reflects the state of the PE dispute in May or at end of March.

Quaest Espírito Santo (A Gazeta, May 4 at 19:28) registers empate técnico between Lula and Flávio in the 1º turno among Espírito Santo voters. The detailed percentages were not available in secondary sources by deadline of this edition. Real Time Big Data national was published on May 4 (VEJA, CartaCapital, Revista Fórum), showing "dispute after the president's defeats"; the complete numbers by candidate were not made available in secondary sources by deadline of this edition.

For additional regional context, the portal Investiga MS reported that Flávio Bolsonaro would be 11.47pp ahead of Lula in Mato Grosso do Sul (no TSE registration disclosed). O Globo reported that polls in four states show difficulty for Flávio's allies among female voters. Next waves (public registrations at TSE, cross-referenced via AFOS API): May 6 is predicted mega-bomb day with seven polls — DATATRENDS (n=4,000), NEOBE (n=1,008), 100 Cidades (n=1,200), Ideia/Canal Meio (n=1,500), VOX BRASIL (n=1,200), Instituto Franca (n=1,067), SETA (n=1,200), totaling ~10,700 respondents; May 7 with J J COELHO (n=1,203).

3. What the press covered

In the institutional field, Roberto Cidade (União Brasil), president of the Amazonas Legislative Assembly, was elected governor of the state in unanimous indirect election on May 4 for interim mandate through October 2026 elections (G1, Folha de S.Paulo, O Globo, Agência Brasil). The vacancy was created by Wilson Lima's resignation, made official via Official Journal on April 4, 2026, to become ineligible and run for Senate in October. Serafim Corrêa was elected vice. For Roraima, UOL reported that the supplemental election for governor will be on June 21.

In the government field, Folha de S.Paulo reported that "Lula's double defeat intensifies narrative of government fragility on social networks." Tribuna da Internet and Portal AZ reported that Lula's Senate defeat strengthens Flávio and pushes centrists toward new alliance. G1 brought agenda-piece "Lula aims at ending 6x1 shift through dialogue with evangelicals, and Flávio seeks Catholic vote" — fragmented religious dispute with opposing vectors. Plantão Brasil reported that Lula's popularity rises with activism reaction against Congress. Minha Bahia reported that Lula kept Jaques Wagner in Senate leadership after internal criticism. Diário do Estado reported that Lula analyzes new STF nomination after rejection of Messias.

In the opposition field, Gazeta do Povo published piece "Flávio advances and Northeast is no longer guaranteed territory for Lula." The same outlet reported that Caiado does not have explicit support from PSD governors in the presidential race — sign of fragmentation in the pre-candidate's party base (on Polymarket, Caiado fell to 1.25% in the presidential but had extreme movement in 3rd place to 19%, with low liquidity). Portal Jamildo reported that Flávio Bolsonaro faces resistance in the Northeast, where the majority prefers Lula.

In the institutional and judicial agenda, Estadão reported that "STF advances on cases with electoral impact and may sideline TSE operations in 2026." CNN Brasil reported that "Master data received by INSS CPI reaches 30 GB of material." SBT News published that Vorcaro's cell phones will be sent to USA and Israel for analysis. Brasil 247 reported that PF is making task force to close list of authorities with privileged jurisdiction in Master case. Blog do BG registered that Lula is advised to declare support for Master CPI.

4. Divergences of the day

In summary

1. Lula in persistent decline; gap at unprecedented level in cycle. Four consecutive days of decline in Polymarket (from 38.50% on May 1 to 36.50% on May 4), with gap widening to +7.75pp. No clear triggering event on May 4 that explains the magnitude — reading is digestion and continuation of the trajectory.
2. Zema recovers in presidential race in counter-trend movement. After four days below 5%, rises to 5.05% (↑1.30pp). Coincides with ceding leadership in 3rd place market (from 39.5% to 38%), suggesting probability redistribution toward the presidential.
3. Roberto Cidade governor AM in unanimous indirect election. Is the most relevant new institutional event of the day, confirmed by four independent sources. Vacancy created by Wilson Lima's resignation on April 4 is not today's event — only the effect (indirect election) is.
