Brazilian presidential election 2026: No candidate wins an outright majority in the first round (October 4, 2026) — runoff takes place on October 25, 2026

Pending ✦ AI-generated prediction Published on 21. July 2026 · Predicted for 4. October 2026 · Based on: Historical Cycle
Probability
54%

Lula da Silva (PT) seeks re-election (open prediction: Lula wins the election). Historical pattern: in 2022, Lula received only 48.4% in round 1 — just below the required absolute majority (>50%) — and won only in the runoff. Without Bolsonaro as a candidate (due to election ban following conviction), a new right-wing candidate (Tarcísio de Freitas, Romeu Zema or similar) is likely to consolidate the conservative electorate. Brazilian election analysts (Datafolha, Quaest) predominantly expect a runoff. This prediction is compatible with the open Lula-wins prediction (he can win in round 2).

Data basis for this prediction
  • Brasilien-Wahl 2022: Lula 48,4 % Runde 1, Stichwahl 30. Oktober (TSE / Reuters)
  • Bolsonaro ineligible 2026: Wahlverbot nach Verurteilung (Brazilian Electoral Court TSE, 2023)
  • Tarcísio de Freitas / Romeu Zema als rechte Kandidaten 2026 (Datafolha Umfragen, 2025/2026)
  • Datafolha / Quaest: Mehrheit erwartet Stichwahl in Brasilien 2026 (Folha de S.Paulo, 2026)
Verdict: Pending
This prediction is still open. It will be evaluated automatically against real-world sources after its due date.

Berlin state election (20 September 2026): SPD receives more than 18.0% of valid votes cast (confirmed by Berlin Returning Officer or tagesschau.de by 21 September 2026)

The SPD received exactly 18.4% in the 2023 Berlin state election and has since been in opposition. Current polls (August/September 2026) put the SPD at 19–22%, making a result above 18.0% likely. Headwinds: ongoing federal political controversy and competition from BSW (which, per existing prediction, is expected below 5%). The 18.0% threshold is just below the 2023 result and would only be missed in a dramatic collapse. No Polymarket market; Metaculus aggregate implies ~65% for SPD above 18%.

Berlin Abgeordnetenhaus election (September 20, 2026): FDP falls below 5.0% of valid votes and fails to enter the Abgeordnetenhaus (confirmed by Berlin returning officer or tagesschau.de by September 21, 2026)

Both current Berlin polls place the FDP far below the 5% threshold: INSA (Sept 2–4, 2026): 3.0%; Infratest dimap (Aug 27–31, 2026): FDP below the statistical detectable threshold. The Berlin FDP has not reached the 5% mark in any poll since spring 2026. Clearing the hurdle would require a simultaneous systematic error of 2+ points from both institutes — historically near-unprecedented. This is the highest-confidence prediction of the entire Berlin election.

Swedish Riksdag election (September 13, 2026): Liberalerna (L) falls below 4.0% and fails to clear the parliamentary threshold (confirmed by Valmyndigheten by September 14, 2026)

Current polls show Liberalerna well below the 4% threshold: Indikator Opinion (fieldwork to September 4, 2026): 2.2%; PolitPro election trend (as of September 9, 2026): 2.7%. Neither institute identifies meaningful upward momentum. The party was part of the Tidö coalition but suffered from its image problems. Even with maximum systematic polling error of +1.5 points, Liberalerna would remain below 4.2%. Failing to enter the Riksdag would cost the governing coalition its parliamentary majority.
