Week of complete arc at the top: the signal is not at the final level of the gap, it's in the speed with which the market tested and rejected a thesis. On Monday (June 2), Flávio Bolsonaro surged +4.20pp to 33.40% and Lula yielded to 39.50%, compressing the gap Lula × Flávio from +11.30pp to +6.10pp in 24 hours — the narrowest point of the cycle. Two documented triggers: the support of Tarcísio de Freitas for Flávio (ruling out a third way) and the US tariff hike being credited to the opposition. Over the next four trading sessions, the movement reversed entirely: as the tariff hike/PIX was reframed as a liability for Flávio (the 'TarifFlávio'), the senator returned all gains, closing at 27.25% (vol USD 6.50M) against Lula 40.50% (vol USD 6.17M), with the gap reopening to +13.25pp (snapshot June 7) — above the pre-surge level. The presidential contract accumulates around USD 96.7M, so the arc was priced with real money, not thin-book noise. With no new national poll in the window (the Vox June 5, gap +8.5pp in the 1º turno, remains the reference), the market operated as an early sensor of a narrative that the institutes will only test in the Quaest of June 10, likely national round. The negotiable divergence of the week is the arc itself: those who hedged saw 'gap stable at ~+9pp'; those who read the components saw the market abandon the right-wing reconcentration in four days.
1.Executive Summary
Week June 2-6 concentrated the strongest repricing of the cycle and unwound it within the same interval. The contract that moved was the top-tier matchup: Flávio surged +4.20pp on Monday with support from Tarcísio and the tariff narrative, compressing the gap to +6.10pp, and returned all gains over the next four trading sessions as the tariff/PIX issue became a liability for the opposition. The pricing reading is not the final gap level (+13.25pp), but rather the amplitude and direction of the reversal: the market priced a five-point compression and unwound it in four days, with robust volume. Polls did not track the intra-week movement (no new national round), so the market operated as an early sensor of a thesis that Quaest on June 10 will only now test. Snapshot closed on June 7 at 20:02 BRT (markets operate 7 days; Sunday's data is the most recent on the covered window).
2.Why AFOS does not smooth
The majority of the aggregation industry reduces divergence through weighted averaging — "consensus tracker" models treat intra-week differences as noise to cancel out. This week, that is exactly the error to avoid: the average would erase the only signal that mattered, which was the arc.
Why it matters: the gap opened the week at +11.30pp, collapsed to +6.10pp on Monday and reopened at +13.25pp on Sunday. A simple average would deliver 'stable gap around +9pp' and discard the entire signal. The components tell the story: Flávio +4.20pp on Monday (spike) and −6.15pp on the week's net (reversal), Lula practically flat. The financial market financed the thesis of right-wing reconcentration via Tarcísio + tariff hike and abandoned it when the tariff framing inverted. The magnitude and speed of the reversal are the signal — not the smoothed level.
Unlike Edition №2, in which the week's movement was slow rotation within the third way without a research catalyst, this week had documented triggers from both sides of the arc: Tarcísio's support and the tariff shock in compression (02/Jun), and the inversion of the tariff framing in reopening (03-06/Jun). The AFOS Tradeoff reports both extremes of the arc side by side and maintains amplitude as an observed variable. The missing test — a national survey — arrives in Quaest on 10/Jun, the first significant print since the Vox on 05/Jun.
3.Weighted scenarios for the week
Three plausible paths for the screenshot window 08-13/Jun:
Gap remains wide (range +12 to +14pp), with Lula consolidated as favorite and the tariff hike/PIX continuing as opposition's liability. The Quaest from June 10, if confirmed nationally, validates Lula's advantage in line with Vox from June 5 (+8.5pp in the 1º turno). Market and polling converge in direction, though the market prices a larger gap than the 1º turno of polling. Net-neutral for BRL.
The Quaest poll from June 10 shows a reconcentration of the right larger than priced in, repeating the signal from June 2, and the gap compresses back to the +8 to +10pp range. Implicit: the market overreacted to the tariff shock reversal, and Flávio's pullback (−6.15pp) was an overshoot. The history of the week itself shows that this movement can occur within 24 hours.
Event of high institutional impact shifts the landscape outside electoral dynamics: acute developments in the Master case at the STF or Flávio's criminal complaint against Lula gaining traction. The minister impeachment contract (5.15%) signals that the market is not pricing in imminent institutional rupture; repricing here would require a new trigger.
4.Indicator Grid
| Contract | Current | Δ week | Vol USD acc. | Implied reading |
|---|---|---|---|---|
| Flávio — winner | 27.25% | ↓6.15pp in the week | 6.50M | Fully reversed the 02/Jun spike (33.40%); tariff increase became a liability |
| Lula — winner | 40.50% | ↑1.00pp in the week | 6.17M | Recovered the point ceded on June 2; top anchored |
| Lula–Flávio Gap | +13.25pp | ↑7.15pp in the week | — | Reopened above pre-spike level; largest amplitude of the cycle |
| Renan Santos — winner / 3rd way | 17.35% | ↑0.50pp in the week | 6.66M | Highest live book volume; diverges ~11pp from polls (~6%) |
| Renan — 3rd place [1º turno](/en/glossary#primeiro-turno) | 45.00% | ~flat in the week | 76k | Favorite for 3rd place; ahead of Zema (25%) and Caiado (18%) |
| Flávio — 2nd place [1º turno](/en/glossary#primeiro-turno) | 63.50% | ~flat in the week | 61k | Isolated leader of 2nd place even with the return in the winner's market |
| Camilo Santana — winner | 3.75% | ↑2.60pp em 24h | 3.18M | Isolated jump on June 07, with no clear event; low conviction, to monitor |
| [STF](/en/glossary#stf) impeach <2027 | 5.15% | ↓0.35pp in the week | 80k | Low institutional risk; thin volume, weak signal |
| [PL](/en/glossary#pl) plurality Senate | 73.00% | ↓2.50pp in the week | 243k | Dropped from 75.50% (June 2); broad favoritism maintained |
5.Liquidity and market structure
The five largest volumes in the entire book are in probability contracts ≤0.65% — Tarcísio (USD 12.46M), Eduardo Bolsonaro (9.47M), Carlos Massa (9.39M), Eduardo Leite (7.32M) and Michelle (7.27M), all with legacy positions never unwound. It is legacy volume, not current traction; none is an active contender in that range. Read "low price + high volume" as concentrated conviction already priced in and resolved, not as live interest — in Tarcísio's case, the volume is remnant from when he was quoted as a candidate, before the support for Flávio sealed on June 2. The relevant data for the week sits just below the top-5: the contenders with material probability — Renan (6.66M), Flávio (6.50M) and Lula (6.17M) — cluster around USD 6.5M, and Renan leads the accumulated volume among active contenders, sustaining a probability (17.35%) that diverges ~11pp from what polling measures (~6%).
The 5 largest accumulated volumes account for ~USD 45.9M (~47%) of the presidential market (total ~USD 96.7M). The cross-reading of price × volume for the week is at the top: Flávio returned −6.15pp of probability on an accumulated volume of USD 6.50M, meaning the reversal of the reconcentration thesis was priced with real flow, not shallow book. Low-volume spikes (USD <500k) in individual contracts should be treated as noise until confirmation of recurrent flow — as in the case of Camilo's jump (07/Jun).

Source: TSE registry via AFOS API. There are 16 qualified surveys (n≥1.000) in the June 8–12 window; the registry classifies them as state-level (generic UF), but the Quaest survey of June 10 (n=2.004) is likely a national round based on sample size and press coverage ('on the eve of Quaest'). It is the only print with potential to move national pricing and test the gap arc. Registered ≠ published — inclusion does not guarantee disclosure or figures.
7.Watch list — week triggers
- [Quaest](/en/glossary#quaest) of June 10: testing the wide gap. If confirmed nationally, it is the direct confrontation between the gap of +13.25pp priced by the market and declared intent. Right-wing reconcentration above expectations would reopen the thesis of the surge on June 2.
- Framing of the tariff hike/PIX. The 'TariFlávio' was the driver of this week's reversal. Any shift in attribution (government × opposition) moves the Flávio contract, which has already proven to move +4pp in 24h.
- Master case at [STF](/en/glossary#stf). The request for Moraes' recusal remains active and the TCU filed away Flávio's representation against Lula's ex-daughter-in-law. A sharp development would fuel the impeachment contract, currently at 5.15%.
- Camilo Santana's jump (3.75%). Isolated movement on June 7, without clear event and low volume (USD 3.18M). Speculative position to monitor; only becomes a signal with recurring flow, not with a single spike.
- Judicialization of the pre-campaign. The volume of actions at [TSE](/en/glossary#tse) between Lula and Flávio campaigns grows and may generate decisions with pricing effects even before candidate registration.
8.Methodology
AFOS Tradeoff aggregates three signals without averaging them into a composite: Polymarket (USD-denominated, ~30min latency), polls registered with the TSE (stated 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 in minutes), and exposing the technical number generates misread in lay audience.
