Predicted for 3. November 2026
·
Based on: Speculative
Polymarket assigns 83–84% probability to a Democratic House majority (as of June/July 2026, active market). Historically, the president's party loses an average of 28 House seats in midterms (Roll Call analysis); the current Republican majority is only ~5 seats (c. 220–215). 270toWin and RaceToWH identify 40+ competitive districts, predominantly suburban. Democrats hold a 5–6 point generic ballot lead (as of June 2026). Dampening factors: gerrymandering, high GOP rural turnout, Iran crisis could briefly trigger a rally-around-the-flag effect. Calibration anchored to Polymarket 83% with a small discount for remaining 4-month uncertainty: 81%.

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.
