US Midterm Elections (3 November 2026): Democratic Party wins majority in the US House of Representatives (net at least 218 of 435 seats, confirmed by AP or NBC News by 5 November 2026)

Hit ✦ AI-generated prediction Published on 13. September 2026 · Predicted for 3. November 2026 · Based on: Speculative
Probability
42%

Polymarket prices Democratic Senate control at 54% (as of 13 September 2026). The House of Representatives is a separate, often contrarian market. Historical average since 1946: the president's party loses a net ~24 House seats at midterms — a strong structural signal favouring Democrats (against a Trump Republican majority). Cook Political Report flags ~35–40 toss-up districts. A Democratic House majority is a plausible but not base-case scenario; implied market probability derived from Senate data and historical patterns: approx. 42%.

Data basis for this prediction
  • Polymarket: Demokraten US-Senat 2026: 54 % (Stand 13. Sep. 2026)
  • Historische Midterm House-Verluste Präsidentenpartei: ⌀ –24 Sitze seit 1946 (FiveThirtyEight-Archiv)
  • Cook Political Report: ~35–40 Toss-up House-Distrikte (Aug./Sep. 2026)
  • Polymarket-Handelvolumen US-Senat 2026: 4,3 Mio. USD (Stand Sep. 2026)
Verdict: Hit
Die Vorhersage ist eingetreten. Die Demokraten gewannen bei den Midterms am 3. November 2026 die Mehrheit im US-Repräsentantenhaus klar: Laut AP-Projektionen und übereinstimmenden Medienberichten (CBS News, CNN, CNBC, Yahoo News) erzielten die Demokraten ca. 253–254 Sitze gegenüber ~162 für die Republikaner – weit über der 218er-Schwelle. Ausschlaggebend war u.a. Trumps Zustimmungsrate von nur 38 % sowie der von 89 % der Wähler als entscheidend bewertete Anstieg der Lebenshaltungskosten. Damit bestätigte sich das historische Strukturmuster (Partei des amtierenden Präsidenten verliert House-Sitze bei Midterms), auf das die Prognose gestützt war – sogar deutlich stärker als erwartet.

Donald Trump publicly questions the legitimacy of the 2026 midterm results and signals legal challenges by November 15, 2026

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).

Alberto Núñez Feijóo (PP) secures parliamentary majority with Vox coalition and becomes Spanish Prime Minister — General Election 29 November 2026 (confirmed by Junta Electoral Central or AP by 1 December 2026)

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.
