Predicted for 20. July 2026

Based on: Historical Cycle
CSIS and Bloomberg analysis projects the LDP-Komeito coalition losing its Upper House majority, driven by voter anger over rising rice prices, the 2024 LDP fundraising scandal, and stagnant real wages. The DPP under Tamaki Yūichirō benefits as a centrist-populist alternative; polls pegged the party at 18–27 new seats. An open Cassandra prediction already forecasts ≥15 seats; this prediction raises the bar to ≥20, consistent with the existing forecast (≥20 implies ≥15). No prediction market available; estimate from poll midpoint.

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.
