1. Prediction market

In the Polymarket presidential race, Lula rose to 45.50% (↑2.00pp in 26h, vs 43.50% at May 18 close) and Flávio Bolsonaro fell to 28.15% (↓3.40pp, cycle low since inception). The gap between the two, which had narrowed to +11.95pp on May 18, reopened to +17.35pp Lula — a ↑5.40pp movement in 26 hours, the largest daily movement of the month. Accumulated volume in the presidential market: USD 78.85M, with the Lula contract at USD 5.54M and Flávio at USD 5.70M.

The third way reorganized. Renan Santos surged to 12.55% (↑2.85pp in 26h) and consolidated the top of the third way in the presidential race, above Romeu Zema. In the 3rd place market, Renan took the lead with 35.50% (↑4.00pp), surpassing Zema, who collapsed to 28.50% (↓8.00pp in 26h). Caiado, in the same market, fell to 13.50% (↓4.00pp). The migration is asymmetric: Flávio yields and the market prices Renan as the primary recipient, not Zema or Caiado.

In the 2nd place market, Flávio remains at 62.50% (↑0.50pp) — the PL electoral base holds in the runoff scenario despite the decline in the presidential race. Lula fell to 14.50% (↓1.50pp) and Renan rose to 9.50% (↑0.60pp in 26h, ↑1.80pp in 48h). Haddad recovered to 4.25% (↑1.70pp in 26h), gaining relevance as an internal PT hedge.

The contract on STF minister impeachment before 2027 registered a slight recovery to 6.05% (↑0.75pp in 24h vs the cycle low of 5.30% on May 18), but remains below the 8% pre-launch baseline. In the Senate, PL remains stable at 78.50% (clear dominance), while Republicanos collapsed to 4.20% (↓6.80pp vs the May 17 peak of 11.00%) — returning all recent gains.

In the 2026 inflation bands, the high tail suffered the day's most material movement. The 7.00%+ band collapsed to 3.30% (↓5.35pp in 26h vs 8.65% on May 18), and the combined bands above 6.50% fell to 9.00% (↓5.05pp in 26h, ↓6.85pp vs the May 17 peak of 15.85%). Central band 5.00-5.49% remains at 28.00% (stable), and the 4.50-4.99% band rose to 21.75% (↑3.25pp). Technical reading: the market withdrew weight from the extreme fiscal scenario without moving the central band.

2. What the polling institutes recorded

AtlasIntel published its first national poll after the Flávio-Vorcaro audio, with sample n=5,000. In the first round, Lula registered 47.0% and Flávio 34.3% — a gap of +12.7pp. In the runoff, Lula 48.9% × Flávio 41.8%, gap of +7.1pp. Relative to the same institute's previous poll, Flávio dropped 6 points in the runoff (was 47.8%). Rejection of Flávio rose from 49.8% to 52.0%, and the survey also found that 47.4% of voters fear a Flávio election while 40.5% fear Lula reelected. Gazeta do Povo reported that AtlasIntel included mention of the audio in the questionnaire for this round — the company denies that this impacted the result.

Quaest published in parallel another snapshot: 32% of voters point to Lula's reelection as the best outcome, 24% indicate a Bolsonaro family return, and 22% prefer an outsider victory. The Datafolha of May 16 (1st round Lula 38% × Flávio 35%, gap +3pp; 2nd round 45×45) remains the last reference point for the São Paulo anchor poll — record available on the TSE disclosure portal under protocol BR-074892026. The gap between AtlasIntel and Datafolha in the first round is 9.7pp — the largest divergence between two national institutes in this cycle.

The next expected publication is Datafolha on May 22, with sample n=2,004 and explicit scenario including Michelle Bolsonaro as a replacement hypothesis on the PL ticket — direct test of the right's reorganization that Polymarket is already discussing (Michelle presidential 2.25%, 2nd place 1.55%, replacement narrative with low traction in the market even with public discussion).

📅 Research calendar — next 7 days

Polls registered with the TSE with release scheduled between May 20 and May 26. Inclusion in the table does not mean publication is confirmed — institutes may delay or cancel release. Filter applied: sample ≥ 1,000. Each protocol linked to the TSE public query.

Source: public record from TSE disclosure portal and AFOS Analytics API. 🔥 highlights samples ≥ 3,000. Status "registered ≠ published" — confirmation of effective release requires verification from two primary sources before citing numbers.

3. What the press covered

Flávio Bolsonaro's team filed a request with the TSE to suspend the release of the AtlasIntel survey — institutional escalation via TSE as an attempt to block the information circuit. In parallel, columnist José Casado wrote in VEJA that Flávio had discussed his withdrawal from pre-candidacy with his father and was attempting to contain damage within the PL — treatment as a signed report, not as consolidated fact, given that the withdrawal itself was not formally announced.

In government news, Folha de S.Paulo reported that Lula brought Jorge Messias to an event with electoral tone before formally communicating to allies about the resubmission of the nomination to the STF. O Globo reported in parallel that the president's insistence on Messias's nomination irritates Senate president Davi Alcolumbre. The observational reading: the government treats the resubmission as a political priority even with signs of friction with the Senate, and the Polymarket for STF impeachment remained low (6.05%) throughout the day — the market does not price this tension as an institutional threat.

Still in government news, a cabinet minister acknowledged to Folha that the tax on the blouses "was a mistake" and confirmed that the Flávio-Master link will formally enter the reelection campaign. For the third way, O Globo reported that the replacement of Aldo Rebelo by Joaquim Barbosa in the Democracia Cristã pre-candidacy provoked internal split and threat of judicial action — a sign that the center space remains fragmented even with the new name.

4. Day's divergences

In summary

1. Published AtlasIntel confirmed part of what the market had already priced, but the residual difference of 4.65pp between Polymarket and survey suggests that the Vorcaro impact remains partially outside the survey's picture. The next Datafolha (May 22, with Michelle scenario) is the next data point of divergence.

2. The reorganization of the third way was asymmetric: Renan Santos absorbed the market migration (presidential 12.55%, 3L top 35.50%); Zema gave up the 3L top for the first time (28.50%, ↓8.00pp); Caiado also lost position (3L 13.50%, ↓4.00pp). Market did not treat all of the non-Bolsonarist right the same way.

3. The extreme fiscal tail (inflation ≥6.50%) collapsed 5.05pp in 26 hours to 9.00%, an atypical movement for a day with electoral survey as central event. Technical reading: the inflation market appears to react to the government's institutional signaling (admission of error, legislative recalibration) in parallel to the political movement — not as a direct reflection of the survey.
