Predicted for 4. October 2026
·
Based on: Statistical Pattern
AS/COA Poll Tracker (Sep 25, 2026) shows Lula at 47% and Bolsonaro at 45%; with 13 candidates splitting the remaining 8–10%, neither can mathematically reach >50% of valid votes. Brazil's constitution (Art. 77 §2) mandates a runoff on October 25 if no candidate wins outright. No specific Polymarket/Kalshi market found; own estimate 90% based on consistent polling. Distinct from the existing 'Lula places 1st' prediction — this forecasts the structural result (mandatory runoff), not the ranking.
Data basis for this prediction
- AS/COA Brazil 2026 Presidential Poll Tracker: Lula 47 %, Bolsonaro 45 % (Stand 25.09.2026)
- Al Jazeera: 'Brazil's Lula and Bolsonaro still essentially tied in new poll' (25.09.2026)
- Brasilianische Verfassung Art. 77 §2: Stichwahl zwingend bei Nicht-Erreichen absoluter Mehrheit
- 13 registrierte Kandidaten (TSE, Stand 27.09.2026) — Reststimmen schließen 50%-Schwelle aus
Verdict: Hit
[Vorzeitig entschieden] Runoff bestätigt – weder Lula noch Flávio Bolsonaro erreichten absolute Mehrheit im ersten Wahlgang. Stichwahl am 25. Oktober 2026 notwendig. Alle Vorwahlumfragen zeigten beide unter 50%. Quelle: Bloomberg, Al Jazeera.

Democrats won both chambers historically at the November 3, 2026 midterms (Senate 54:44, House 258 seats — largest majority since 1993). Trump's disapproval rating stands at 62% (FiveThirtyEight, Nov 2026). Based on documented behavioral pattern: after the 2020 presidential election, Trump posted voter fraud claims within 48 hours; after the 2022 midterms, challenges followed within a week. Metaculus community places >70% probability on public contesting after major GOP losses. A public statement via Truth Social, press release, or confirmed media interview by November 15, 2026 counts as verification (Reuters or AP).

Ukrainian, US, and Russian negotiators convene November 10–11 in Abu Dhabi. Russia conducted large-scale long-range strikes on Ukrainian energy infrastructure and logistics hubs on November 3–4; Ukraine responded with drone strikes on the Ryazan refinery. Positions on territory and security guarantees remain far apart. No Polymarket or Kalshi market covers this specific event; historical base rate for failure of comparable trilateral talks: >80%.

Spain holds a general election on 29 November 2026. Polymarket prices Feijóo as next PM at 85%, Kalshi at 82% — both serve as anchors. A separate Polymarket market gives PP+Vox a 92% probability of a joint majority (>176/350 seats). Current polls (Sondaxe) show PP at 29.2% narrowly ahead of PSOE (26.9%); Vox is tracking slightly higher. Feijóo failed to form a government in 2023, but market odds reflect the lesson learned: PP+Vox is now seen as stable enough. No deviation from market anchor warranted.
