Predicted for 3. November 2026
·
Based on: Statistical Pattern
In the 2026 US Midterms, 34 Senate seats are contested; Republicans must defend 20, Democrats 14. The historical pattern shows the president's party loses an average of 6 Senate seats in second-term midterms. Trump (second term, in office since January 2025) faces this structural headwind. Polymarket (September 7, 2026) shows a 'Democratic lead in generic ballots and key races'; specific Senate data are not quantified. Structurally, Democrats sit at 47 seats, 3 short of majority — flipping 3 is plausible but uncertain. The existing open prediction covers Democrats in the House; the Senate majority is an independent, additional event.

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.

With 97% of votes counted, Republican incumbent Roger Wicker leads by just 28 votes per NBC News live results (04.11.2026) — one of the closest Senate races in history. Mississippi election law requires an automatic recount when the margin falls below 0.5% of total votes, expected to conclude by 15–20 November. The remaining 3% of ballots originate primarily from rural precincts with historically higher Republican turnout, giving Wicker a slight statistical edge. No specific Polymarket market for Mississippi was identified.

Polymarket gives Peltola a 72% win probability (as of November 3, 2026). The Democrat benefits from Alaska's Ranked Choice Voting system, which structurally favors cross-partisan candidates, as well as strong support from the Indigenous population and Alaska Native organizations. The national environment weighs on Sullivan: Polymarket gives Democrats a 72–77% probability of winning the Senate majority and 95% in the House. Early mail-ballot returns show a slight pro-Democratic lean in Alaska. Because Alaska uses ranked choice, a final count is not expected until November 5.
