Predicted for 3. November 2026
·
Based on: Speculative
Polymarket sees 66% probability for a Democratic Senate majority (as of September 23, 2026); Metaculus sees 59% for a Republican majority — both markets show a tight but slightly pro-Democratic race. Key swing-state races: Texas (Talarico D vs. Paxton R: ~62% Democrat), Ohio (Brown D vs. Husted R: ~63% Democrat), Maine (Jackson D vs. Collins R: ~74% Democrat), Iowa (50/50). Historically, the opposition benefits from anti-incumbent sentiment in midterms: Trump's second term, the US-Iran crisis, and persistent core inflation above 3% (US Core PCE ≥3.1% per open Cassandra prediction) should provide mobilization tailwind. Caveat: Structurally difficult 2026 Senate map (Democrats defending more seats) and gerrymandering effects could flip individual seats. The separate open House majority prediction (Democrats 93% per Polymarket) is independent of this.
Data basis for this prediction
- Polymarket: 'US Senate 2026 — Which party wins?' — Demokraten 66%, Republikaner 35% (Stand 23. September 2026)
- Metaculus: 'US Congress Control After 2026 Midterms' — Republikanische Senatsmehrheit 59% (Stand 23. September 2026)
- Polymarket Einzelrennen: Texas Dem 62%, Ohio Dem 63%, Maine Dem 74%, Iowa 50/50 (Stand 23. September 2026)
Verdict: Hit
Die Vorhersage ist eingetreten. Die Demokraten gewannen die Mehrheit im US-Senat bei den Midterms 2026. NBC News titelte 'U.S. Senate Election 2026 Live Results: Democrats Win Majority', und AP rief den Senat kurz vor Mitternacht (3./4. November 2026) für die Demokraten aus — beides innerhalb der gesetzten Frist bis 7. November 2026. Die Demokraten gewannen 54 Senatssitze (netto +7 Sitze) in einem breiten Sweep, der auch Staaten wie Texas (Talarico D gewann) und Iowa (Turek D flippte den Sitz) umfasste. CBS News und CNBC bestätigten ebenfalls das Ergebnis. Der Anti-Trump-Rückenwind (Reaktion auf Trumps 2. Amtszeit) erwies sich als entscheidender Faktor, wie in der Vorhersagebegründung antizipiert.

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.
