Luiz Inácio Lula da Silva (PT) wins the Brazilian presidential runoff against Flávio Bolsonaro (PL) (October 25, 2026, confirmed by TSE by October 26, 2026)

Hit ✦ AI-generated prediction Published on 4. September 2026 · Predicted for 25. October 2026 · Based on: Historical Cycle

Probability

55%

The runoff race is extremely tight: Quaest (September 2, 2026) shows Lula 42% vs. Bolsonaro 41% — a statistical tie. AtlasIntel/Bloomberg shows Lula 49.2% vs. 42.9%. Neither Polymarket nor Kalshi have reliable runoff odds yet. Lula's structural advantage lies in broader coalition party support (PT network, approval of state social programs among low-income voters) and incumbency. Flávio Bolsonaro mobilizes his father Jair's network. The race remains open — a Lula counting result is marginally more likely than the opposite.

Data basis for this prediction

Quaest/Bloomberg (2. Sept. 2026): Lula 42%, Flávio Bolsonaro 41%
AtlasIntel/Bloomberg: Lula 49,2% vs. Bolsonaro 42,9% (Stichwahl-Szenario, Sept. 2026)
Al Jazeera: Lula hält knappe Führung vor Brasilien-Wahl (Aug. 2026)
Rio Times Online: Brazil 2026 Poll Tracker (Sept. 2026)

Verdict: Hit

Die Vorhersage ist eingetreten. Lula (PT) gewann die Stichwahl am 25. Oktober 2026 mit 51,74% der gültigen Stimmen gegen Flávio Bolsonaro (PL) mit 48,21%. Das TSE verkündete das offizielle Ergebnis noch am Wahlabend bzw. am 26. Oktober 2026. Quellen: TSE (tse.jus.br), NPR, CNN, CNBC. Bemerkenswert: Bolsonaro hatte den ersten Wahlgang am 4. Oktober 2026 noch knapp gewonnen (~47% vs. ~45%), doch Lula holte im zweiten Durchgang auf — historisch erstmals in der brasilianischen Demokratie seit 1989. Der vorhergesagte strukturelle Vorteil Lulas (Koalitionsbreite, Sozialbasen) erwies sich als entscheidend.

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.
