Will the Workers' Party nominate Lula for President of Brazil by August 15?

According to the latest prediction market data for the query “Will the Workers' Party nominate Lula for President of Brazil by August 15?”, traders have formed a strong consensus.

Currently, Yes is dominating the market with an overwhelming 87.5% chance of winning. No follows in second place at 12.5%. The betting volume for this specific market has already reached $57.4K, reflecting intense industry interest.

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

• Yes (87.5%): Currently commanding the highest probability, Yes is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 88¢, signaling a high degree of market conviction.

🥈 Tier 2: The Primary Challengers

• No (12.5%): Positioned as the most viable alternative, No maintains a 12.5% chance of resolving true. Its “Buy Yes” shares currently trade at 13¢.

The 2026 Brazil presidential election is currently scheduled to be held on October 4, 2026. Political parties must file candidate registration applications with the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) for the 2026 Brazil presidential election by August 15, 2026, 7:00 PM Brasília time (UTC−03:00).

This market will resolve to "Yes" if the Workers’ Party (Partido dos Trabalhadores, PT) files a candidate registration application nominating Luiz Inácio Lula da Silva for President of Brazil by August 15, 2026, 7:00 PM Brasília time (UTC−03:00). Otherwise, this market will resolve to “No”.

A filing by a coalition (coligação) or party federation (federação partidária) that includes the PT and names Luiz Inácio Lula da Silva as its presidential candidate will also qualify.

This market will resolve based on the filing date (Data de Autuação) of an applicable Application for Registration of Candidacy (Requerimento de Registro de Candidatura, RRC). An Application for Registration of Individual Candidacy (Requerimento de Registro de Candidatura Individual, RRCI) will not qualify for resolution of this market.

The primary resolution source will be official filings from the Superior Electoral Court (TSE); however, a consensus of credible reporting may also be used.

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 Yes currently trades at 87.5%, but our AI places its Fair Value at just 83%. This creates a large negative EV Gap of -4.5%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies No as the premium value opportunity on the board. While the market only assigns it a 12.5% trading probability, our AI’s Fair Value assessment sits at 17% — yielding an impressive +4.5% EV Gap.
