Hit ✦ AI-generated prediction Published on 8. September 2026 · Predicted for 25. October 2026 · Based on: Historical Cycle

Probability

58%

According to Polymarket (8 September 2026), the probability of Lula advancing to the runoff stands at 88–90% (open prediction). Lula leads Flávio Bolsonaro (PL) by 2–8 percentage points in late-August 2026 polls; runoff simulations show a close race within the margin of error (AS/COA Poll Tracker). As the incumbent, Lula benefits from state transfer programmes (Bolsa Família expansion) and has a structurally stable base in major cities and poorer north-eastern regions. Flávio Bolsonaro mobilises the conservative electorate more effectively than his father did in 2022, but trails Lula in runoff scenarios.

Verdict: Hit

Die Vorhersage ist eingetreten. Lula da Silva (PT) besiegte Flávio Bolsonaro (PL) im zweiten Wahlgang am 25. Oktober 2026 mit 51,79 % der gültigen Stimmen (64.256.232) gegenüber 48,21 % (59.826.041). Das Tribunal Superior Eleitoral (TSE) bestätigte Lulas Wiederwahl offiziell noch am Wahltag. Alle Kernelemente der Vorhersage – Stichwahl am 25.10.2026 zwischen genau diesen beiden Kandidaten, Sieg Lulas, TSE-Bestätigung bis 26.10.2026 – stimmen überein. Bemerkenswert: Lula hatte den ersten Wahlgang hinter Flávio Bolsonaro abgeschlossen, gewann aber die Stichwahl – ein historisches Novum in Brasilien.

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.

Roger Wicker (Republican) retains the US Senate seat in Mississippi after recount — confirmed by AP or NBC News by 20 November 2026

With 97% of votes counted, Republican incumbent Roger Wicker leads by just 28 votes per NBC News live results (04.11.2026) — one of the closest Senate races in history. Mississippi election law requires an automatic recount when the margin falls below 0.5% of total votes, expected to conclude by 15–20 November. The remaining 3% of ballots originate primarily from rural precincts with historically higher Republican turnout, giving Wicker a slight statistical edge. No specific Polymarket market for Mississippi was identified.

Mary Peltola (Democrat) wins the US Senate seat in Alaska against Dan Sullivan (Republican) — US Midterm Elections November 3, 2026 (confirmed by AP or NBC News by November 5, 2026)

Polymarket gives Peltola a 72% win probability (as of November 3, 2026). The Democrat benefits from Alaska's Ranked Choice Voting system, which structurally favors cross-partisan candidates, as well as strong support from the Indigenous population and Alaska Native organizations. The national environment weighs on Sullivan: Polymarket gives Democrats a 72–77% probability of winning the Senate majority and 95% in the House. Early mail-ballot returns show a slight pro-Democratic lean in Alaska. Because Alaska uses ranked choice, a final count is not expected until November 5.
