Predicted for 13. September 2026
·
Based on: Statistical Pattern
Current Swedish election polls (as of September 4, 2026, 9 days before the election): Social Democrats 28.9%, Sweden Democrats 19.6%, Moderates 17.3%, Left Party 7.8%, Center Party 7.6%, Greens 7.4%, Christian Democrats 6.6%, Liberals 2.5%. SD leads in 2nd place by 2.3 percentage points over the Moderates (M). For a rank change, M would need to gain at least 2–3 percentage points in nine days — unlikely given a stable gap confirmed by multiple polling institutes. No specific Polymarket market for 'SD second-strongest party' available; calibration based on poll consistency and historical Swedish electoral volatility (typically ±1–2 points deviation from polls). Note: This prediction is independent of the coalition outcome and compatible with the existing prediction about the Tidö majority loss.

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%.

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.

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.
