Based on: Speculative
Polymarket and Kalshi now give Democrats a slight edge for Senate control in 2026: 51% Democrats vs. 49% Republicans (as of July 22, 2026). As recently as June 2026, Republicans led at ~58% on Kalshi. The dramatic reversal reflects escalating Iran/Middle East tensions, a Democratic generic ballot lead, and polling advantages in swing states — Georgia Senator Jon Ossoff holds a clear lead in current polls. 35 Senate seats are up in 2026, 23 currently held by Republicans. This prediction covers the Senate and is separate from the already-open House prediction (also favouring Democrats).

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.
