Predicted for 13. September 2026
·
Based on: Historical Cycle
The latest PolitPro election trend (6 Sep 2026) shows S at 28.7% in first place — ~9 percentage points ahead of Sverigedemokraterna (19.5%) and 11pp ahead of Moderaterna (17.5%). Seat projection gives S 105 of 349 seats. A second-place party closing a 9pp gap in 5 days would be historically unprecedented. No Polymarket market for the 'largest party' outcome specifically. Distinct from the open prediction 'S > 28.0%': this asks about seat rank, not vote share.
Data basis for this prediction
- PolitPro Election Trend Schweden: S 28,7 %, SD 19,5 %, M 17,5 % (Stand 6.9.2026)
- PolitPro Sitzprojektion: S 105 / SD 72 / M 64 Mandate (Stand 6.9.2026)

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.

Die Linke won 9.9% in MV's 2021 state election. Nationally the party collapsed to ~3.5% in 2025. MV is arguably the party's last eastern stronghold. The open platform prediction puts BSW below 5% in MV, reducing direct competition for left-leaning voters. No MV-specific September 2026 poll retrievable; extrapolation from eastern German trends suggests a borderline 5–7% range. Assessment: ~50/50, slight lean toward clearing the threshold given structural voter anchoring in MV.
