Predicted for 13. September 2026
·
Based on: Historical Cycle
Social Democrats poll at 30.5% in the PolitPro Election Trend and at a 30-day average of 31.8% (Polara.se, August 2026). The party benefits from incumbent fatigue against the Kristersson government (M/SD/KD/L) and strong competency perceptions on social and economic issues. The left bloc (S + V + MP) polls at 46.5% and is likely to enable government formation. The 30.0% threshold is near the lower polling range; historically Swedish polls slightly underestimate S by 1-2 percentage points. Liberalerna likely fails the threshold (separate open Cassandra prediction). No Polymarket market for this exact threshold.

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.
