Language Divergence: EN vs PT Sources
English sources emphasize democracy/institutional concerns with Bolsonaro resurgence. Portuguese sources focus on kitchen-table economics — inflation, fuel, food costs.
{'indicator': 'IPCA_12m', 'value': 4.14, 'change_pct': 8.7, 'threshold': 4.5, 'severity': 'MEDIUM', 'assessment': 'Approaching inflation ceiling amid fuel/food pressures.

Runoff
Race State
The race has fundamentally shifted from Lula-favored to genuinely competitive. For the first time, a Bolsonaro family member leads the incumbent president in quality polling, while Lula's approval has collapsed to 29% — the lowest of his presidency. Right-wing consolidation behind Flávio is complete, creating a unified opposition bloc. Economic pressures are mounting with inflation approaching the ceiling and food costs consuming nearly half the minimum wage. The government's massive diesel subsidies provide short-term relief but create fiscal vulnerabilities. We are witnessing a potential structural realignment where the incumbent advantage is neutralized by economic discontent.

What is this?
The Brazil 2026 Election Monitor is an AI-powered political intelligence dashboard that combines Gemini CLI (Google) for real-time web search and data collection with Claude (Anthropic) for structured analysis and assessment. It provides regular snapshots of the presidential race, tracking polling, structural dynamics, economic indicators, and narrative trends.
How does it work?
Each report is generated through an automated pipeline: Gemini CLI searches official APIs (IBGE, BCB, AwesomeAPI) and news sources, collecting polling data, economic indicators, and political developments. This raw data is then processed by Claude, which applies credibility weighting, cross-references sources, detects structural changes, and produces the analysis you see above.
How to use it wisely
- This is a monitoring tool, not a prediction engine
- Polling data is weighted by pollster credibility (Tier A/B/C) but all polls have margins of error (typically ±2-3%)
- Sentiment analysis detects narrative shifts, not voter intent
- Structural change detection requires confirmation across multiple runs before being marked CONFIRMED
- Polymarket odds reflect trader sentiment, not election outcomes
- News sources may include AI-searched results — URLs should be verified before citing
- Economic thresholds are based on historical precedent, not guaranteed electoral triggers
- This dashboard is updated weekly (or as scheduled) — it captures snapshots, not real-time data
