Predicted for 13. September 2026
·
Based on: Statistical Pattern
Current polls (PolitPro, Sep 2026) show Socialdemokraterna (S) at ~28.5% and Sverigedemokraterna (SD) at ~19.5% — a 9 percentage point lead. Seat projection: S ~104 seats vs SD ~71 seats. This prediction is consistent with open predictions (S >27.5% vote share, red-green bloc wins majority) but goes further in explicitly quantifying the party gap. An outcome where SD overtakes S would be a historical surprise.

In the 2022 Riksdag election, Moderaterna received 19.1%. Polls for August/September 2026 place M at 17–20%. Although SD has overtaken them as the largest right-wing party and the left-green bloc is forecast to win a majority per existing open predictions, a collapse below 16% is historically unlikely. No Polymarket market available.

Two recent polls show Die Linke in Berlin well above the 18% threshold: Forsa (August 4–18, 2026) at 22%, INSA (August 7–13, 2026) at 19%. In Berlin, Die Linke has a strong base (East Berlin strongholds). Headwind comes from BSW as a competing party that could siphon votes on the left fringe. Both polls are clearly above the threshold; calibrated at ~65%.

Metaculus (September 2026) gives Republicans ~59% probability of Senate majority; Polymarket and RealClearPolling confirm ~59–62%. Of 35 seats up for election, Republicans currently hold 53 vs. 47 Democrats. Democrats need a net gain of +4 seats — the Senate map favors Republicans (23 R seats vs. 12 D seats in play). Consistent with open Cassandra prediction 'Democrats win House with ≥6 net seats': a split Congress with Democratic House and Republican Senate is the most likely scenario (Metaculus: 49.2%).
