Brazilian presidential election, 1st round (October 4, 2026): Luiz Inácio Lula da Silva (PT) receives more than 42.0% of votes cast (confirmed by Tribunal Superior Eleitoral or Reuters by October 5, 2026)

Hit ✦ AI-generated prediction Published on 21. September 2026 · Predicted for 4. October 2026 · Based on: Statistical Pattern

Probability

62%

Lula da Silva leads Brazilian polls as incumbent president. His main opponent Flávio Bolsonaro (PL, son of election-banned Jair Bolsonaro) mobilizes the Bolsonarist base but lags significantly. The open platform prediction 'no candidate above 50% in round 1' implies Lula's share between 40% and 49%; specifying >42% (below the absolute majority threshold) is informative and contradicts no existing prediction. Polymarket sees Lula winning the runoff at >80% probability (indirect calibration for first-round share). Own estimate for >42% in round 1: ~62%.

Data basis for this prediction

Brasilianische Präsidentschaftswahl, 1. Wahlgang: 4. Oktober 2026 (Tribunal Superior Eleitoral)
Polymarket: Lula gewinnt Stichwahl >80 % Wahrscheinlichkeit (indirekte Kalibrierung, Sept. 2026)
Cassandra-Plattform offen: 'Lula gewinnt Stichwahl gegen Flávio Bolsonaro am 25. Oktober 2026'
Cassandra-Plattform offen: 'Stichwahl erforderlich — kein Kandidat über 50 % in Runde 1 (4. Oktober 2026)'

Verdict: Hit

Lula da Silva erzielte im 1. Wahlgang am 4. Oktober 2026 laut TSE-Auszählung (99,9 % ausgezählt) 45,16 % der gültigen Stimmen (53.879.538 Stimmen) — damit klar über der Schwelle von 42,0 %. Quellen: TSE (tse.jus.br), Americas Quarterly, Rio Times Online. Beide Kandidaten (Lula 45,16 %, Flávio Bolsonaro 47,03 %) zogen in den 2. Wahlgang am 25. Oktober 2026 ein, was auch die implizierte Bedingung 'kein Kandidat über 50 %' bestätigt.

Donald Trump publicly questions the legitimacy of the 2026 midterm results and signals legal challenges by November 15, 2026

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).

Alberto Núñez Feijóo (PP) secures parliamentary majority with Vox coalition and becomes Spanish Prime Minister — General Election 29 November 2026 (confirmed by Junta Electoral Central or AP by 1 December 2026)

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.
