Predicted for 25. October 2026
·
Based on: Historical Cycle
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.
Data basis for this prediction
- Polymarket: Lula zieht in Stichwahl ein – 88 % (Stand 8. September 2026)
- AS/COA Poll Tracker: Lula führt Bolsonaro 2–8 PP in August-2026-Umfragen; Stichwahl-Simulation innerhalb Fehlerquote
- Tribunal Superior Eleitoral: 2. Runde angesetzt für 25. Oktober 2026
Verdict: Pending

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%.

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.

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.
