Predicted for 20. September 2026
·
Based on: Ongoing Event
Berlin polls (DAWUM.de, early September 2026) show BSW at only 3.4–3.6%, well below the 5% threshold. Reaching 5% by election day would require an exceptional late surge with no polling evidence. Analogous to the FDP, which is also below 5% and predicted to fail the threshold in a separate open prediction.
Data basis for this prediction
- BSW Berlin Umfragen 3,4–3,6 % (DAWUM.de, Stand Anfang Sep. 2026)
- Wikipedia: 2026 Berlin state election — Umfragentabelle (Sep. 2026)
- Vergleich FDP Berlin ~3,4 % (DAWUM.de, Sep. 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%.

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.
