Predicted for 13. September 2026
·
Based on: Historical Cycle
Statistics Sweden poll (June 2026): S + V + MP jointly achieve their own absolute majority without the Centre Party. Current aggregators (PolitPro, August 2026) show the Red-Green bloc ~12 points ahead of the Tidö alliance. Liberals polling at ~2.5%, well below the 4% entry threshold, reducing the Tidö bloc to ~41.5%. Lines.com market: Tidö winning majority below 30%. A S+V+MP outright majority would pave the way for Magdalena Andersson as new Swedish PM. Estimated probability: ~67%.

Verdict: Miss
Das Dreier-Bündnis S+V+MP erzielte laut Valmyndigheten (Endergebnis ~17. September 2026) zusammen nur rund 151 Mandate (S≈100, V≈29, MP≈22) – deutlich unter der absoluten Mehrheit von 175. Die Mehrheit von 176 Mandaten erforderte zwingend das Centerpartiet (C, 25 Mandate), das in der Vorhersage ausdrücklich ausgeschlossen wurde. Die Vorhersage scheiterte vor allem daran, dass (a) die Sozialdemokraten schwächer abschnitten als in den Hochrechnungen (≈28 % statt prognostizierter ~30 %+), (b) Miljöpartiet und Vänsterpartiet zusammen nicht stark genug waren, um die Lücke zu schließen, und (c) Centerpartiet nicht dem Tidö-Block beitrat, aber auch nicht die S+V+MP-Dreierkoalition zur eigenständigen Mehrheit machte.

Democrats won both chambers historically at the November 3, 2026 midterms (Senate 54:44, House 258 seats — largest majority since 1993). Trump's disapproval rating stands at 62% (FiveThirtyEight, Nov 2026). Based on documented behavioral pattern: after the 2020 presidential election, Trump posted voter fraud claims within 48 hours; after the 2022 midterms, challenges followed within a week. Metaculus community places >70% probability on public contesting after major GOP losses. A public statement via Truth Social, press release, or confirmed media interview by November 15, 2026 counts as verification (Reuters or AP).

Ukrainian, US, and Russian negotiators convene November 10–11 in Abu Dhabi. Russia conducted large-scale long-range strikes on Ukrainian energy infrastructure and logistics hubs on November 3–4; Ukraine responded with drone strikes on the Ryazan refinery. Positions on territory and security guarantees remain far apart. No Polymarket or Kalshi market covers this specific event; historical base rate for failure of comparable trilateral talks: >80%.

Spain holds a general election on 29 November 2026. Polymarket prices Feijóo as next PM at 85%, Kalshi at 82% — both serve as anchors. A separate Polymarket market gives PP+Vox a 92% probability of a joint majority (>176/350 seats). Current polls (Sondaxe) show PP at 29.2% narrowly ahead of PSOE (26.9%); Vox is tracking slightly higher. Feijóo failed to form a government in 2023, but market odds reflect the lesson learned: PP+Vox is now seen as stable enough. No deviation from market anchor warranted.
