Why this matters:
This 17% probability indicates that current market participants view Fernando Haddad as an unlikely winner of Brazil's 2026 presidential election. Haddad, who lost the 2022 runoff to Jair Bolsonaro and currently serves as Finance Minister under President Luiz Inácio Lula da Silva, faces headwinds from both consolidation of right-wing opposition candidates and potential economic conditions that could affect voter sentiment by election day. The probability could shift materially based on economic performance metrics, approval ratings, and whether opposition parties successfully unite behind a single candidate. The Brazilian presidential election scheduled for October 2026 represents the primary catalyst that will ultimately resolve this market, though intervening months will likely see significant probability swings tied to polling data, legislative actions, and political developments.

Key factors:
- Haddad's performance as Finance Minister and Brazil's economic trajectory through 2026, including inflation and growth rates, which directly influence incumbent coalition viability
- Consolidation or fragmentation of right-wing opposition candidates, as a unified challenger typically polls stronger than a divided field
- Current polling trends showing Haddad's standing relative to leading opposition candidates, with most recent surveys indicating he trails principal rivals
- Approval ratings of President Lula and the broader left-wing coalition, since Haddad's prospects depend substantially on voter satisfaction with the current administration
- Turnout patterns and electoral dynamics, particularly among youth voters and regions where opposition strength has historically been concentrated

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
