Predicted for 3. November 2026
·
Based on: Historical Cycle
Polymarket shows 60% probability of a Democratic Senate majority after the 2026 Midterms (as of September 16–18, 2026); Kalshi is around 55%. Drivers: Democrats leading in competitive races in North Carolina, Maine, and Ohio; voter backlash against the Trump-Republican administration (classic midterm pattern); growing dissatisfaction with Fed rate hikes to 3.75–4% and energy price burden. The result would complement the open Cassandra forecast 'Democrats win US House,' creating a fully Democratic-controlled Congress — historically rare in a party's first midterm, but favored by structural factors in 2026. Forecast anchored to Polymarket's 60% probability.

Verdict: Hit
Die Vorhersage ist eingetreten und wurde deutlich übertroffen. Laut NBC News und CBS News gewannen die Demokraten bei den Midterms 2026 die Senatsmehrheit mit 54 Sitzen (Republikaner: 44), was weit über der prognostizierten Schwelle von ≥51 Sitzen liegt. Demokraten flippten 7 republikanisch gehaltene Sitze, darunter überraschend Texas, South Carolina und Kansas. NBC News rief die demokratische Senatsmehrheit aus – eine der in der Vorhersage genannten Bestätigungsquellen. Treiber waren Wählergegenreaktion auf Trump (klassisches Midterm-Muster), wie in der Prognose beschrieben. Die 60-%-Wahrscheinlichkeit von Polymarket erwies sich als zutreffend.

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.
