Predicted for 13. September 2026
·
Based on: Statistical Pattern
Current Swedish election polls (as of September 4, 2026, 9 days before the election): Social Democrats 28.9%, Sweden Democrats 19.6%, Moderates 17.3%, Left Party 7.8%, Center Party 7.6%, Greens 7.4%, Christian Democrats 6.6%, Liberals 2.5%. SD leads in 2nd place by 2.3 percentage points over the Moderates (M). For a rank change, M would need to gain at least 2–3 percentage points in nine days — unlikely given a stable gap confirmed by multiple polling institutes. No specific Polymarket market for 'SD second-strongest party' available; calibration based on poll consistency and historical Swedish electoral volatility (typically ±1–2 points deviation from polls). Note: This prediction is independent of the coalition outcome and compatible with the existing prediction about the Tidö majority loss.

Verdict: Miss
Das amtliche Endergebnis (festgestellt von Valmyndigheten am 19. September 2026) zeigt: Moderaterna erhielt 19,85 % (70 Mandate), Sverigedemokraterna 17,48 % (62 Mandate) – damit wurde M zweitstärkste Partei, nicht SD. Gegenüber den Umfragen vom 4. September (SD 19,6 %, M 17,3 %) trat exakt das als unwahrscheinlich eingestufte Szenario ein: M holte ~2,5 Prozentpunkte auf und SD verlor ~2 Punkte. Die Vorhersage unterschätzte die Mobilisierungsdynamik und die Volatilität in den letzten Wahlkampftagen.

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.
