Based on: Speculative
The French Senate election on September 27, 2026 is an indirect vote by grands électeurs (local elected officials), renewing 178 of 348 seats. RN polls at roughly 35% of national voting intention. Decisive, however, is the electoral college structure: the indirect system strongly favours parties with deep, established local roots (Républicains, PS). In the last Senate election in 2023, RN grew from 2 to 22 seats — a large jump, but from an extremely low base. While RN made gains in the March 2026 municipal elections, these new officeholders only took up their grands électeurs roles in March 2026 and have yet to build mature local campaign infrastructure for the Senate race. No Polymarket signal available. We estimate 58% probability that RN wins fewer than 40 of the 178 contested seats.

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.
