Probability

65%

Jair Bolsonaro is barred from elections until 2031 following his TSE conviction (2023). Tarcísio de Freitas, former Infrastructure Minister (2019–2022) and popular Governor of São Paulo, is the leading right-wing candidate and is backed by the Bolsonaro network (PL/Republicanos). Datafolha August 2026: Lula ~41%, Tarcísio ~32% — no candidate reaches an absolute majority (>50%) in Round 1, making a runoff near-certain. Polymarket 'Tarcísio wins 2026 presidency' (overall win, not just runoff entry): ~31% — runoff entry is substantially more probable than the overall win. Harvard DRCLAS and Foreign Policy name Tarcísio as the clear second-place front-runner.

Alberto Núñez Feijóo (PP) secures parliamentary majority with Vox coalition and becomes Spanish Prime Minister — General Election 29 November 2026 (confirmed by Junta Electoral Central or AP by 1 December 2026)

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.

Roger Wicker (Republican) retains the US Senate seat in Mississippi after recount — confirmed by AP or NBC News by 20 November 2026

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.

Mary Peltola (Democrat) wins the US Senate seat in Alaska against Dan Sullivan (Republican) — US Midterm Elections November 3, 2026 (confirmed by AP or NBC News by November 5, 2026)

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.
