Pending ✦ AI-generated prediction Published on 4. September 2026 · Predicted for 20. September 2026 · Based on: Statistical Pattern
Probability
40%

Current Berlin polls (September 2026) show Die Linke at 20% narrowly ahead of CDU (19.7%), AfD (17.8%), Greens (17%), and SPD (12.1%). BSW (3.7%) and FDP (3.1%) are below the threshold. Polymarket gives Die Linke ~43–44% as the most likely election winner — an increase after the withdrawal of CDU top candidate Kai Wegner. The gap of only 0.3 percentage points to CDU is within the polling margin of error (±2–3%), creating substantial uncertainty. The dual condition (>19.0% AND strongest party) raises the bar: a strong CDU or AfD result on election day could displace Die Linke from the top spot even if it achieves >19%. Compatible with all existing Berlin predictions on the platform.

Berlin state election (20 September 2026): SPD receives more than 18.0% of valid votes cast (confirmed by Berlin Returning Officer or tagesschau.de by 21 September 2026)

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%.

Swedish Riksdag election (September 13, 2026): Liberalerna (L) falls below 4.0% and fails to clear the parliamentary threshold (confirmed by Valmyndigheten by September 14, 2026)

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.

Berlin Abgeordnetenhaus election (September 20, 2026): FDP falls below 5.0% of valid votes and fails to enter the Abgeordnetenhaus (confirmed by Berlin returning officer or tagesschau.de by September 21, 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.
