Predicted for 3. November 2026
·
Based on: Speculative
On 3 November 2026, 34 Senate seats are contested. Polymarket places the probability of Democrats flipping the Senate at approximately 44% (Republicans retain ~56%, $3.2M volume). Clearly distinct from the existing 'Democrats win the House' prediction (Polymarket ~83-86%); Senate and House races historically often decouple. Democrats benefit from anti-Trump fatigue but must defend comparatively more vulnerable seats. This prediction anchors to the Polymarket estimate of ~44% without significant deviation.

Left-alternative Reiwa Shinsengumi (Tarō Yamamoto) is benefiting from the LDP's historic collapse in trust. In the 2025 Sangiin vote the party won 3 seats; in the February 2026 lower-house election it drew ~2.92% of the PR vote. With further strengthened anti-establishment sentiment and targeted social-policy demands (minimum wage, debt relief), 4–6 seats is plausible. No Polymarket odds available; NHK seat models project a 4–6 seat range.

The EU has adopted 16 Russia sanctions packages since February 2022, most recently the 16th package in January 2026. The average interval between packages in 2025/2026 was approximately 4–5 months — by this cadence, the 17th package would be due in May–August 2026. Political drivers: ongoing hostilities (Russia struck Kyiv with 41 missiles and 125 drones on July 18–19, 2026), active shadow-fleet enforcement, third-country circumvention crackdown, and sustained pressure from the Baltics and Poland. Potential delay due to domestic coalition issues in individual member states (notably Hungary). No Polymarket market.

Pre-election polls for July 2026 project Nippon Ishin at 5–9 seats (of 125 contested) — a clear downtrend from their 2022 peak. Opposition voters increasingly flow to CDPJ and DPP; Ishin suffers from waning reform momentum and internal disputes. Reference: in the 2025 Sangiin election Ishin won only 7 seats. For 2026, polling institutes see the range at 5–9 mandates.
