Predicted for 3. November 2026
·
Based on: Speculative
Polymarket prices a Democratic Senate majority at 52% (as of September 20, 2026; Balance of Power market, over $12.7M traded volume). The generic congressional ballot shows a Democratic lead of 7–9 percentage points, which historically correlates with substantial seat gains. Democrats need a net gain of one to two Senate seats to flip the current Republican majority; competitive races in Montana, Ohio, and Arizona are considered decisive. This forecast is deliberately complementary to the existing open prediction on the Democratic House win (218+ seats, 86–90% per Polymarket) — the Senate majority is significantly closer and still undecided. Cassandra adopts the Polymarket anchor of 52% unchanged.

Verdict: Hit
Die Demokraten gewannen bei den Midterms am 3. November 2026 klar die Mehrheit im US-Senat. NBC News projizierte die demokratische Senatsmehrheit fristgerecht (vor dem 7. November 2026). Die Demokraten flippten mindestens 7 Senatssitze (u.a. Kansas, Texas, Ohio, Iowa, North Carolina, South Carolina, Maine) und erzielten ca. 54 Sitze — weit über der für die Mehrheit nötigen Mindestanzahl. Die Vorhersage mit 52 % Wahrscheinlichkeit traf ein; der tatsächliche Ausschlag war sogar deutlicher als erwartet.

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.
