Why this matters:
The 32% probability reflects market expectations that Fernando Haddad, Brazil's Finance Minister, will not win the October 2026 presidential election. This estimate places him as a secondary candidate behind incumbent Luiz Inácio Lula da Silva, who trades at 63%. Haddad's probability is influenced by his association with the current administration—historically an asset in Brazilian politics, but potentially limiting if voters seek change. The perception of economic management, inflation trends, and his ability to build coalition support among regional governors and parties will materially affect his viability. The election occurs on October 2, 2026, providing the definitive resolution point. Until then, economic data, candidate announcements, and major policy developments will shape whether Haddad consolidates support as a likely successor or remains a secondary option.

Key factors:
- Haddad's probability depends significantly on Lula's sustained approval and whether he emerges as the consensus successor candidate versus other potential contenders from Lula's coalition
- Economic performance metrics—particularly inflation rates and unemployment—between now and October 2026 will influence voter appetite for continuity versus change
- Formal candidacy announcements and coalition negotiations among major political parties remain incomplete; Haddad must secure sufficient party backing to be electorally viable
- Regional dynamics and support from state governors, who control machine politics in Brazil, will determine campaign infrastructure and grassroots mobilization capacity
- Potential legal or political challenges to other candidates (including Bolsonaro-aligned figures like Flávio Bolsonaro) could consolidate or fragment the anti-incumbent vote

## 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.
