Predicted for 20. September 2026
·
Based on: Statistical Pattern
According to the latest PolitPro poll trend for Berlin (as of September 6, 2026), AfD stands at 17.9% – 2.9 percentage points above the 15% threshold. Even with a ±3pp polling error (as historically observed in the Berlin context), AfD would remain above 15%. Calibration history shows AfD shares in east-German-leaning elections have tended to be overestimated rather than underestimated recently; Berlin has a structurally capped AfD ceiling, but 15% is a conservative threshold. Polymarket 'Berlin State Election Winner' shows $3.47M in trading volume.
Data basis for this prediction
- PolitPro Berlin-Wahltrend: AfD 17,9% (Stand 6. Sep 2026, politpro.eu)
- The Berliner: 'Die Linke surges to historic high in Berlin poll' (abgerufen 7. Sep 2026)
- Polymarket 'Berlin State Election Winner': $3,47 Mio. Volumen (Stand 4. Sep 2026)
- Cassandra-Kalibrierung: AfD Sachsen-Anhalt 2026 (Polling 33%, Ergebnis 20,8%) – Überschätzungsrisiko in West-Ost-Übergangslagen

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.
