Based on: Historical Cycle
Japan's House of Councillors (Sangiin) election on July 20, 2026 sees 125 of 248 seats contested. Historical turnout in Sangiin elections: 2022 = 52.05%, 2019 = 48.80%, 2016 = 54.70%, 2013 = 52.61%. The threshold of 52.5% sits just above the 2022 reading. Mobilization factors in 2026: sustained inflation pressure, JPY weakness, policy discontent, and the escalated Hormuz crisis as a geopolitical shock. Compared to 2022, there is more opposition mobilization potential. No Polymarket market on voter turnout; the historical average of the last four Sangiin elections is ~52.0%. Exceeding 52.5% is possible but not the majority view — hence 44%.

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.
