Predicted for 3. November 2026
·
Based on: Speculative
Polymarket assigns 83–84% probability to a Democratic House majority (as of June/July 2026, active market). Historically, the president's party loses an average of 28 House seats in midterms (Roll Call analysis); the current Republican majority is only ~5 seats (c. 220–215). 270toWin and RaceToWH identify 40+ competitive districts, predominantly suburban. Democrats hold a 5–6 point generic ballot lead (as of June 2026). Dampening factors: gerrymandering, high GOP rural turnout, Iran crisis could briefly trigger a rally-around-the-flag effect. Calibration anchored to Polymarket 83% with a small discount for remaining 4-month uncertainty: 81%.

The LDP won a historic landslide in Japan's lower house election on February 8, 2026 (316/465 seats, 68%) under PM Takaichi. This momentum should carry into the upper house election. 60/125 new seats (48%) is well below the lower house share — the separate coalition absolute majority question (LDP + Komeito > 125/248 total) is independently tracked (open prediction: fails). We price LDP alone reaching ≥60 seats at 42%. No Polymarket quote.

Per existing prediction, the USA has already imposed expanded secondary sanctions against Iran by July 18, 2026 (in response to the Hormuz crisis). Historically, within 1–2 weeks of Iran sanctions escalations, OFAC targets third-country actors circumventing sanctions: Chinese intermediaries and 'teapot refineries' buying discounted Iranian oil were repeatedly designated in the 2018/2019/2020 cycles. With oil price pressure from the Hormuz blockade, Washington faces strong political pressure to curb Chinese sanctions-busting. Own estimate: ~52%.

An existing open prediction already forecasts Nippon Ishin no Kai at ≥8 seats. This prediction sets a more ambitious threshold of ≥15 seats and is fully compatible with the existing one (≥15 implies ≥8). Ishin has positioned itself as a reform-oriented third force capitalising on declining trust in the LDP-Komeito coalition (2025 Sangiin election: LDP coalition lost majority). LDP's landslide lower-house victory in February 2026 (316 seats) may make Ishin more attractive as an upper-house alternative. A Polymarket Japan election market exists (as of July 14, 2026) listing Ishin as a relevant actor; no specific seat-count market available. Own estimate based on historical strength and political dynamics: 30%.
