Predicted for 3. November 2026
·
Based on: Speculative
Republicans currently hold a 53-47 Senate majority. Democrats need a net +4 seats to flip control. The 2026 election covers Class 3 senators, including several competitive swing-state seats. Historically the president's party loses an average of 5 Senate seats at midterms; Trump's second term with unpopular tariff policy and social spending cuts may energise voters. No specific Polymarket Senate-control 2026 market available (as of July 17, 2026). Estimate based on historical regression. Distinct from the open prediction 'Democrats win House majority'.

Existing open predictions imply a high probability that LDP + Komeito will lose their absolute Sangiin majority in the 20 July 2026 election. Historical pattern from the 2025 Sangiin election: the LDP-led coalition lost its majority; PM Ishiba initially vowed to stay (23 July 2025) but resigned on 7 September 2025; DPP (Tamaki) initially declined formal cooperation. A swift public cooperation pledge within 7 days of the election (by 27 July) is historically atypical and should therefore be assigned a low probability – the pattern suggests a reflection period before formal talks. The question is binary and clearly verifiable via press reports after the deadline.

Wisconsin elects a new governor on November 3, 2026. Tony Evers (D) is constitutionally term-limited after two terms. Wisconsin is a genuine swing state: Biden won it in 2020 by just +0.6%, Evers was re-elected in 2022 by ~+3.4%. Historical midterm patterns under a Republican president (Trump 2nd term) favour Democrats in competitive gubernatorial races (+6–8pp average vs. a normal election). The Milwaukee metro area and college cities (Madison, Green Bay) are demographically shifting toward Democrats. No Polymarket or Kalshi market found for this specific race; estimate based on structural analysis and midterm dynamics.

At the July 20, 2026 Sangiin election, 125 of 248 Upper House seats are up for election. In 2022, the LDP+Komeito coalition won 76 of 125 seats (61%). Current forecasts show the coalition facing significant losses: three opposition parties alone (Ishin ≥10 + DPFP ≥15 + Sanseito ≥8 = ≥33 seats minimum per Cassandra database). Combined with the CDP and other opposition forces, a result of fewer than 60 seats for the coalition would be a historic defeat. Polls in July 2026 (NHK, Asahi Shimbun) show continued declining support for the LDP.
