Based on: Speculative
The 2026 US midterm elections feature Class 3 Senate seats – many of which were won by Democrats in the 2020 Biden wave (including Arizona, Georgia, Nevada, Pennsylvania, Wisconsin). Republicans currently hold a Senate majority (~53:47). In mid-term cycles with opposition sentiment against the presidential party, Republicans historically perform well in Senate defense. Polymarket and Kalshi price Republicans to hold the Senate at approximately 60–65%. This prediction complements – without contradicting – the existing open forecast 'Democrats win House majority' (a separate chamber).
Data basis for this prediction
- Polymarket: Republikaner halten US-Senat – implizierte ~62% Wahrscheinlichkeit (Stand 13.07.2026)
- Kalshi: US Senate Majority 2026 – Republicans favored ~63% (Stand 13.07.2026)

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%.

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.
