Polymarket shows for the 2026 Midterms (c. August 2026): Democrats sweep both chambers 50%, Republican Senate + Democratic House 34%, Republican sweep 12%, other 4%. This implies a Democratic Senate victory probability of approximately 54%. Kalshi shows Democrats at ~55% for Senate control (August 2026). Cook Political Report identifies five toss-up Senate seats (PA, WI, AZ, NV, GA), all slightly Democratic-leaning in the latest polls. The existing Cassandra forecast covers the House; this prediction covers the Senate as a separate resolution.

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.
