To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• 39%+ (86.5%): Currently commanding the highest probability, 39%+ is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 87¢, signaling a high degree of market conviction. This contract alone has generated $54.3K in volume.

🥈 Tier 2: The Primary Challengers

• 36-39% (7.4%): Positioned as the most viable alternative, 36-39% maintains a 7.4% chance of resolving true. Its “Buy Yes” shares currently trade at 7¢.
• <30% (1.6%): Sitting in third place with a 1.6% probability, the market shows measured skepticism toward <30%, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~4.5%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes 33-36% (1.4%), and 30-33% (0.7%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like 33-36% are still attracting notable interest.

A presidential election is scheduled to take place in Brazil on October 4, 2026.

This market will resolve according to the percentage of valid votes received by Flávio Bolsonaro in the first round of this election.

The percentage of valid votes received by the specified candidate will be determined by dividing the total number of valid votes the candidate receives in the first round by the sum of all valid votes cast in the first round.

If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.

If the specified candidate does not appear on the ballot in the first round, or otherwise receives no valid votes, this market will resolve to the lowest range bracket.

This market will resolve based on the official vote count.

If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.

If the result of this election isn't known definitively by June 30, 2027, 11:59 PM ET, this market will resolve to the lowest range bracket.

This market will resolve based on the result of the election, as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the Brazilian government, including the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., https://dadosabertos.tse.jus.br/).

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome 36-39% currently trades at 7.4%, but our AI places its Fair Value at just 2.3%. This creates a large negative EV Gap of -5.1%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies 30-33% as the premium value opportunity on the board. While the market only assigns it a 0.7% trading probability, our AI’s Fair Value assessment sits at 7.5% — yielding an impressive +6.8% EV Gap.
