The developments from Federal Police Operation Compliance Zero against senator Ciro Nogueira reached the market and Congress on May 8, with Polymarket presidential pricing Lula stable at 37.50% and Flávio Bolsonaro at 43.85% (↓1.15pp), gap compressing to +6.35pp (vs +7.50pp on May 7). Percent Brasil in Mato Grosso published on May 8 shows Flávio with 44.6% and Lula with 29.8% in the 1º turno (n=1.200, registration TSE BR 00726/2026). Mendonça awaits opinions from Federal Police and PGR to decide between Papuda and house arrest for Daniel Vorcaro. Quaest launches new national round on May 8 (n=2.004, field through May 11, publication expected May 13).

1. Prediction market

In the Brazil Presidential Election market, Lula held at 37.50% (stable after the ↑1.00pp on May 6) and Flávio Bolsonaro gave up 1.15pp to 43.85% (from 45.00% on May 7), compressing the gap between both to +6.35pp (vs +7.50pp on May 7). There was no specific triggering event on May 8 for this movement, and the data is consistent with technical reading of exit from the peak observed the previous day. In the contest for 2nd place, Flávio consolidated at 65.50% (stable) and Lula held at 19.50% (stable); Camilo Santana gave back 2.00pp to 2.85% (from 4.85%), while Geraldo Alckmin surged 1.15pp to 2.35% (from 1.20%).

The contest for 3rd place registered strong reorganization: Romeu Zema recovered the lead, reaching 35.00% (↑1.50pp from 33.50%); Renan Santos held at 32.50% (stable); Caiado surged 1.50pp to 16.00% (from 14.50%), approaching the contest between the top two; Flávio recovered to 5.10% (↑0.90pp). In the presidential race, Haddad surged 0.70pp to 4.05% (from 3.35%) — largest individual presidential movement of the day; Zema surged 0.30pp to 4.25% (from 3.95%); and Caiado surged 0.30pp to 1.45%, returning above the 1% threshold.

The STF impeach line gave back 1.00pp to 13.00% (from 14.00%), returning to the May 4 level after a two-day recovery-reversal movement. The movement occurred on a day when Carlos Andreazza's column in Estadão classified the operation against Ciro Nogueira as "the opening of the foreseeable arrival of Master investigations to Congress", and when Folha's Painel column reported that the government assesses that Lula's meeting with Trump complicates new sanctions. The marginal correction suggests that the market interpreted the set of events as reinforcement of regular institutional action.

In the Senate, massive reorganization: PL gave up 1.00pp to 81.50% (maintains absolute leadership); MDB surged 0.60pp to 6.40%; União Brasil gave up 0.65pp to 4.65%; PSB gave back 1.70pp to 3.60% (from 5.30%); and Republicanos collapsed 4.60pp to 0.75% (from 5.35%) — largest Senate repricing of the day.

In 2026 inflation, reverse reorganization after the colossal jump on May 6: high bands (≥6.50%) gave up from 60.65% to 44.70% (↓15.95pp). The 5.00-5.49% band surged 12.85pp to 33.60%, recovering the lead; the 7.00%+ band gave back 7.15pp to 19.25%; and the 6.50-6.99% band gave back 8.80pp to 25.45% — partial repricing that reverses part of the previous day's movement without undoing the fundamental jump.

2. What the institutes recorded

Percent Brasil in Mato Grosso published on May 8 (n=1.200, field between April 30 and May 3, margin 2.83pp, registrations TSE BR 00726/2026 and MT 06232/2026) shows Flávio Bolsonaro with 44.6% and Lula with 29.8% in the 1º turno in MT. In rejection, Lula leads with 46.8% and Flávio appears with 26.6%.

Quaest launched on May 8 its fifth national round of 2026 with field expected through May 11 (n=2.004, cost R$ 433 thousand, hired by Banco Genial), with publication expected for May 13. It is the first survey after three relevant political events: the government's defeat in the nomination of Jorge Messias to the STF, the launch of the Desenrola 2 program, and Lula's meeting with Trump in Washington. In Minas Gerais, Correio Braziliense reported on May 8 that Aécio Neves and Marília Campos lead the contest for the Senate.

The Genial/Quaest from May 6 covering ten states (n=11.646, field between April 21 and 28) and the Paraná Pesquisas in SP updated on May 7 remain as references. Next releases expected: May 10 (3 surveys from Instituto Piauiense de Opinião Pública) and May 11 (D-1) with seven surveys expected totaling approximately 9,270 respondents, according to TSE schedule. The public launch of AFOS Analytics remains scheduled for Tuesday, May 12.

3. What the press covered

The developments from Operation Compliance Zero against Ciro Nogueira dominated the political agenda on May 8. Folha reported on May 8 that Tarcísio denied harm from the operation and that Ciro Nogueira's PP canceled an act for electoral support in São Paulo. VEJA reported that the operation weighs on the climate among Centrão leaders, and [Gazeta do Povo reported that Flávio and Tarcísio distance themselves from Ciro Nogueira after new operation against Banco Master](https://news.google.com/rss/articles/CBMirwFBVV95cUxOSjlNeUlIMGZWNmZna2E5LU9VZ2ViMF80N0xoRUlFRzkydzlYMVNzMkRJRm4tNktXOHdnXzl2elJOUUNSTnR6d1VraHdMNzRhbi1HaVVlOE9UdzdSckZldFFpMlZVLXh6SzMzZmJXazhzYVFNbGdLSGZpQWs3OXRqaUViQkFHWTBlaWw1TDVOamQ2OW1GV0tUa3VQaVhhNEdOZDdOakpSbnR5ZTkxbWlz?oc=5). Also on May 8, Brasil 247 reported that the Planalto directed ministers to avoid comments on the action against Ciro Nogueira, and Hora do Povo reported that the Master allowance scandal leaves Flávio Bolsonaro disoriented. [Jornal O Sul reported that government leader Pimenta demands a CPI on Banco Master and rejects a deal in Congress](https://news.google.com/rss/articles/CBMiqgFBVV95cUxOVXRwcURYa01GZk81c0RSY09WTV9nZ0Znc0IyZDRKamcxczZnY3BkNXJhSkJzMFJQZktjNi1EcWJpOUZVb1ZicDJSN19MRU9IcFRmb3FVYU1Od2hxN2c4MWpWSzJHMnhQQ2FuM1BWaVlPMVVFbE1jOGcxbkFjTEZjQ2xxOU1vQ2JIVlFWRGVaSnMyNnBqRGZPb2I3THNpVUhpNjZVcERDMWk1Z9IBrwFBVV95cUxQclRKV3ZBNks1aEVobS1mM1lhMlFhVm0yMWs2TWRuRUctRzA5OGNPTUZjeDJkNTVmUzRFUW5ReU9aN3o5bFNoM0FfQUthZXROemp6RDE3WC1pZUpnWk5fWmV5bVE2enZhZm95TUMxZ0YwaGVlNmhMdzdtaU5Hen52WFBVZ2x4aWFNV1JMMmh2bjdRRG5LY29sME92Y1ZqWFRzNjFhcnJPZjBJX2tJQjBv?oc=5).

On the meeting between Lula and Trump at the White House, O Globo reported on May 8 that Lula said he told Trump he doesn't want "war" with him and that his dispute is "in the narrative". According to Folha's report on May 8, tariffs dominated the conversation between the two presidents, with minerals and big tech taking a back seat.

In the Master case developments, Mendonça awaits opinions from Federal Police and PGR to decide Daniel Vorcaro's future between Papuda and house arrest. Poder360 reported that Vorcaro proposes returning R$ 40 billion over 10 years, and [Folha reported that a cryptocurrency giant charges Banco Master R$ 1.6 billion in court and requests asset seizure](https://www1.folha.uol.com.br/mercado/2026/05/gigante-das-criptomoedas-cobra-r-16-bilhao-do-master-na-justica-e-pede-penhora-de-bens.shtml). Also on May 8, UOL Notícias reported that Flávio Bolsonaro said, on dosimetry, that Lula had the opportunity to enact law but chose omission.

4. Divergences of the day

Market × state survey MT: Polymarket prices Lula at 37.50% nationally, while Percent Brasil in MT published on May 8 shows Lula at 29.8% and Flávio at 44.6% (gap of 14.8pp in MT). National market does not respond 1:1 to state survey, and Mato Grosso historically votes more to the right; the MT data confirms the national picture without being contradictory, but reinforces the thesis of regional heterogeneity.

Market × institutional event: The STF impeach line gave back 1.00pp on May 8 on a day when [Mendonça (STF) evaluates Vorcaro's fate between Papuda and house arrest](https://oglobo.globo.com/politica/noticia/2026/05/08/mendonca-aguarda-pareceres-de-pf-e-pgr-para-decidir-futuro-de-vorcaro-papuda-ou-prisao-domiciliar.ghtml) and on which Carlos Andreazza's column in Estadão registers the Master operation as institutional routine. The correction suggests reading of continuity, not instability.

Press × Polymarket Senate: Folha and VEJA reported on May 8 that the operation against Ciro Nogueira impacts the Centrão. In parallel, in the Senate market, Republicanos collapsed 4.60pp to 0.75% and MDB surged 0.60pp to 6.40% — repricing that suggests probability reallocation among Centrão parties without change to the denominator (PL maintains 81.50%).

In summary

  1. Polymarket presidential priced Lula stable at 37.50% and Flávio at 43.85% (↓1.15pp), with gap compressing to +6.35pp (Polymarket live). Haddad surged 0.70pp in presidential — largest individual presidential movement of the day.
  2. Operation Compliance Zero against Ciro Nogueira had developments on May 8: Folha, VEJA and Estadão (Andreazza) covered impact on the Centrão and classified operation as the arrival of Master investigations to Congress.
  3. Percent Brasil in MT shows Flávio with 44.6% × Lula 29.8% (field April 30–May 3, n=1.200). Quaest launched new national round with publication expected for May 13. Public launch of AFOS Analytics on May 12 (Tuesday).
