Predicted for 13. September 2026
·
Based on: Statistical Pattern
Current polls (PolitPro.eu, Wikipedia aggregate, as of August 2026): M 17.6%, SD 19.3%, KD 6.4%, L 2.0% – combined 45.3%. At an assumed turnout of ~84%, this corresponds mathematically to approximately 158 seats – well below the required majority of 175. Compounding factor: Liberalerna (L) at 2.0% is well below the 4% threshold and, per open prediction, does not enter the Riksdag, reducing the coalition to M+SD+KD ≈ 43.3% (~151 seats). Even with a maximum polling error of +3 pp for the bloc, no majority is achievable. No Polymarket market found for Tidö coalition majority.
Data basis for this prediction
- PolitPro.eu Schweden August 2026: M 17,6 %, SD 19,3 %, KD 6,4 %, L 2,0 % (politpro.eu, 27.08.2026)
- Wikipedia 2026 Swedish general election: Umfrageaggregat August 2026 (en.wikipedia.org)
- Valmyndigheten: Riksdag 349 Sitze, Mehrheit bei 175 (val.se)
- Offene Cassandra-Vorhersage: Liberalerna (L) scheitert an der 4 %-Sperrklausel
Verdict: Hit
Die Tidökoalition (M+SD+KD+L) erzielte laut offiziellen Ergebnissen der Valmyndigheten gemeinsam 173 Sitze (M 70 + SD 62 + KD 22 + L 19) und verfehlte damit knapp die erforderliche Mehrheit von 175 Sitzen. Die Vorhersage trat somit ein. Allerdings lag die Begründung teilweise falsch: Liberalerna (L) überwand die 4%-Sperrklausel entgegen der Prognose und zog mit 19 Mandaten in den Riksdag ein. Trotzdem reichte es für die Koalition insgesamt nicht zur Mehrheit. Die linke Opposition (S+MP+V+C) erreichte 176 Sitze.

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.
