Based on: Statistical Pattern
LDP government approval per NHK is only 17.9%. Opposition demands to reverse the consumption tax enjoy 76.7% public support. The Sangiin has 248 total seats; 125 are contested on July 20. LDP+Komeito need at least 63 of the 125 new seats to preserve their existing overall majority (currently ~123 seats in the non-renewed bloc). Current polling aggregates (Nikkei, NHK) put the coalition at 45–57 mandates — well below threshold. The existing open prediction that LDP subsequently seeks DPP cooperation implicitly confirms a majority loss.
Data basis for this prediction

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.
