Predicted for 3. November 2026
·
Based on: Statistical Pattern
All 435 House seats are up for election on November 3, 2026. Historically, the sitting president's party (Republicans, Trump in year 2) loses an average of 25–30 House seats in the first midterm. The Republican House majority post-2024 is slim at ~5–10 seats; a net loss of 5–10 seats would flip the chamber. Polling aggregates (FiveThirtyEight/Metaculus, August 2026) give Democrats ~52–55% odds. No Polymarket/Kalshi market for the House directly verified. Consistent with the open prediction that Republicans retain the Senate – a different chamber with different competitive dynamics.

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.
