Signal of the week

Week of the test the market didn't yield to. The June 15-19 window brought the first complete national poll since Quaest (Nexus June 15, CNT/MDA and Futura/Apex June 16), closed by Datafolha June 20, the best snapshot of Flávio in the cycle (2º turno 47 × 43, the tightest gap in the sample; 1º turno 41 × 31). Instead of tightening, the presidential market widened: Lula from 49.50% to 51.50% (↑2.00pp on the week) and Flávio from 26.65% to 25.05% (↓1.60pp), pushing the Lula × Flávio gap from +22.85pp to +26.45pp (↑3.60pp), a new cycle record. The tradeable fact of the week is the opposite direction: in the same window where the best poll for Flávio tightened to +4pp in the 2º turno, the probability of victory priced by the market opened to a record gap. Below the top, the signal is Renan Santos: the third-place contract in the 1º turno jumped from 48% to 62% (↑14.00pp), while the winner contract stayed flat at 14.25% (↓0.40pp) and still diverges ~11.25pp from the 3% that nationals measure in the 1º turno. The presidential contract accumulates ~USD 103M, so the divergence was priced with real money. The next window brings AtlasIntel (June 22) and JOTA n=6,000 (June 25), the largest sample since Datafolha, which will test the record gap again.

1.Executive Summary

Lula × Flávio Gap
+26.45pp
↑3.60pp in the week
New cycle record; market did not compress even after the national poll battery (Nexus, MDA, Datafolha June 20)
Renan · 3rd place
62.00%
↑14.00pp in the week
Prediction market consolidated Renan as favorite for 3rd place; winner contract remained flat (14.25%)
STF impeach <2027
3.60%
~flat for the week
Institutional risk inert despite PF operation on Jaques Wagner; thin volume (USD 82k)

Week June 15-19 ran the first complete national polling batch since the Quaest of June 10: Nexus June 15, CNT/MDA and Futura/Apex June 16, closed by Datafolha of June 20. Instead of compressing the record gap, the market extended it: Lula at 51.50% (vol USD 6.58M) and Flávio at 25.05% (vol USD 6.78M), gap +26.45pp, new cycle record. The richest data point is in direction: the Datafolha of June 20 was Flávio's best print in the sample (2º turno 47 × 43, the tightest), and the market did not reward it, the gap widened in the same window. One step below, Renan's decomposition from Edition №4 hardened: the 3rd place contract jumped to 62% (↑14.00pp) while the winner contract remained flat (14.25%). Snapshot closed on June 21 17:10 BRT (markets operate 7 days; Sunday's data is the most recent on the covered window).

2.Why AFOS does not smooth

The aggregation industry reduces 'the market versus the polls' to a single, smoothed reading. This week, that average is precisely the error: mixing the market's record gap with the tightest 2º turno of the cycle cancels out the fact that defines the window, that the two moved in opposite directions.

Mixing the market gap with the [2º turno](/en/glossary#segundo-turno) from [Datafolha](/en/glossary#datafolha) (47 × 43) produces a '~Lula ahead, open race' that conveys nothing

AFOS Tradeoff reports
market gap +26.45pp (record) × Datafolha 2nd round +4pp (the tightest)
Probability of victory (market) and voting intention (survey) measure different things; the signal is in the OPPOSITE DIRECTION, not in percentage-point-by-percentage-point subtraction
The market did not compress after the most favorable print for Flávio of the cycle
Largest divergence of the week

Why it matters: the Datafolha of June 20 was the best portrait of Flávio in the sample (2º turno 47 × 43, the tightest gap in the cycle; 1º turno 41 × 31). In the same interval, the market took Lula's probability of victory to a record gap (+26.45pp). An aggregated reading would nullify the most useful information: in this window, market and polling pointed in opposite directions. The AFOS Tradeoff reports both side by side and treats the divergence as an observed variable, not as error to smooth. Method caveat: market gap is probability of victory, not vote margin, so the comparison is of direction and conviction, not pp by pp.

Unlike Edition №4, where the signal was Renan's decomposition into two contracts, this week the signal is the market's response to a real test: an entire national polling battery, including the most favorable print to Flávio of the cycle, passed without compressing the record gap. The AFOS Tradeoff registers the divergence in direction between market and research and maintains the ballot box result as the final arbiter. The test continues in the next window, with the JOTA n=6,000 (June 25), the largest sample since Datafolha.

🌐 Track record · globally validated cases

The same framework we apply to Brazil, measuring the distance between the prediction market and polls and checking the signal against actual ballot box results, has already been verified against eight elections across three continents: Peru and Colombia (2026), Chile, Germany and Canada (2025) and United Kingdom, Mexico and United States (2024). In some cases the signal was high divergence; in others, near-zero convergence (Colombia, Germany); and in the United States in 2024 two markets disagreed with each other (the electoral college was correct, the popular vote was wrong), recorded with radical honesty. What validates the method is the actual result, not the direction of the signal, which is why we do not speak of 'validated divergences', but rather of cases checked against what the ballot boxes delivered. It is auditable and open track record, not claims of predictive superiority. The cases are in the AFOS global hub.

3.Weighted scenarios for the week

Three paths for the polling window of June 22-26, with the JOTA n=6,000 (June 25) as the largest sample size since Datafolha:

Base scenario · ~60% probability

AtlasIntel (June 22) and JOTA (June 25, n=6,000) confirm Lula's advantage in line with recent nationals (1º turno ~+10pp), and the market holds the gap in the +24 to +27pp range. Renan stays ~3% in the polls, preserving the ~11.25pp divergence in the winner contract. Market and polls converge on the leader's direction; the market keeps pricing an advantage larger than the 1º turno. Net-neutral for BRL.

Scenario contrary to current pricing · ~30%

A heavy poll print (JOTA n=6,000) shows right-wing reconcentration above market pricing, with Flávio above 31% in the 1º turno, or a 2º turno in the Datafolha range (47 × 43) confirmed by another institute, and the market gap compresses to +18 to +22pp. Implicit: the market overestimated Lula's advantage and is beginning to converge with poll signals. Renan's winner contract recovers some ground if a poll finally registers traction for his name above 3%.

Tail · ~10%

A high-impact institutional event shifts the picture away from electoral dynamics: acute developments in the Master case at the STF, linked to PF operations on Jaques Wagner, or a domestic print far outside consensus. The impeachment contract at 3.60% signals that the market does not price in imminent institutional rupture; repricing here would require a new trigger.

5.Liquidity and market structure

Presidential market · vol. accumulated since openingUSD ~103M

2Carlos Massa (Ratinho Jr.)0.15% prob.USD 10.05M
3Eduardo Bolsonaro0.15% prob.USD 9.75M
4Michelle Bolsonaro1.15% prob.USD 7.79M
5Eduardo Leite0.05% prob.USD 7.55M
Reading anomaly.

The five largest volumes in the entire book remain in probability contracts ≤1.15%: Tarcísio (USD 12.88M), Carlos Massa (10.05M), Eduardo Bolsonaro (9.75M), Michelle (7.79M) and Eduardo Leite (7.55M), all legacy positions never dismantled. It is legacy volume, not current traction; none is an active contender in the range. Read 'low price + high volume' as concentrated conviction already priced in and resolved, not as live interest. The relevant data from the week sits just below the top-5: the contenders with material probability, Renan (7.29M), Flávio (6.78M) and Lula (6.58M), remain clustered around USD 6.5M to 7.3M, and Renan still leads accumulated volume among the live contenders, sustaining 14.25% in the winner (diverges ~11.25pp from 1º turno polls) while the market has pushed him to 62% in the 3rd place contract.

The 5 largest accumulated volumes account for ~USD 48M (~47%) of the presidential market (total ~USD 103M). The cross-reading of price × volume for the week is at the top: the gap opening at a record (+26.45pp) was made on real flow (Lula USD 6.58M, Flávio USD 6.78M), not on shallow book, and in the same window in which the best poll for Flávio tightened. Low volume spike (USD <500k) in individual contract should be treated as noise until confirmation of recurring flow.

Source: TSE registry via AFOS API. The June 22-26 window brings AtlasIntel (Tier 1) and JOTA (n=6,000), the largest sample since the Datafolha of June 20. Registered ≠ published: inclusion does not guarantee disclosure or figures. Filter applied: sample ≥ 1.000.

7.Watch list, week triggers

  1. JOTA (June 25, n=6,000). The largest sample test of the window. A 1º turno below +10pp, or a 2º turno in the Datafolha range (47 × 43) confirmed, strains the record gap of +26.45pp.
  2. AtlasIntel (June 22, Tier 1). A high-reputation institute opens the week; an outlier print reprices the winner contract right on Monday.
  3. Convergence or divergence of the gap. Watch whether the market maintains the gap above +24pp or begins to converge toward the 1º turno polling (~+10pp) after the full national battery.
  4. Renan's Decomposition. The third-place contract jumped to 62%; watch whether it consolidates or if a print with Renan above 3% in the 1º turno revives the winner contract (14.25%).
  5. Case Master / Wagner at the STF. Any action regarding the PF operation against Jaques Wagner that moves the impeachment contract away from 3.60%.

8.Methodology

AFOS Tradeoff aggregates three signals without mediating them into a composite: Polymarket (denominated in USD, latency ~30min), surveys registered with the TSE (declared intent, variable frequency) and 400+ press sources (event flow). When the three diverge, the divergence is the signal, not consensus. USD volume is reported alongside implied probability to separate conviction from artificial spike. Liquidity (book depth) is not cited inline because low liquidity on Polymarket does not mean wrong price (active arbitrage within minutes), and exposing the technical number generates misreading among lay audiences.
