Predicted for 20. July 2026
·
Based on: Statistical Pattern
At the House of Councillors election on 20 July 2026, 125 of 248 upper house seats are contested. Sanseito (参政党), a nationalist micro-party with sharp anti-immigration and anti-establishment positions, is benefiting from pre-election polls indicating a generational mood shift among young voters disenchanted with the LDP and inflation policy. The party surprised observers by entering the upper house in 2022. CSIS forecasts a further rise in protest votes for 2026. No direct Polymarket/Kalshi anchor for Sanseito seat count found; calibrated on CSIS analysis and historical voter shifts. Co-existing open predictions (LDP+Komeito lose majority; DPFP ≥15 seats; LDP alone ≥60 seats) are non-contradictory.

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.
