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%.

The SPD received exactly 18.4% in the 2023 Berlin state election and has since been in opposition. Current polls (August/September 2026) put the SPD at 19–22%, making a result above 18.0% likely. Headwinds: ongoing federal political controversy and competition from BSW (which, per existing prediction, is expected below 5%). The 18.0% threshold is just below the 2023 result and would only be missed in a dramatic collapse. No Polymarket market; Metaculus aggregate implies ~65% for SPD above 18%.

Both current Berlin polls place the FDP far below the 5% threshold: INSA (Sept 2–4, 2026): 3.0%; Infratest dimap (Aug 27–31, 2026): FDP below the statistical detectable threshold. The Berlin FDP has not reached the 5% mark in any poll since spring 2026. Clearing the hurdle would require a simultaneous systematic error of 2+ points from both institutes — historically near-unprecedented. This is the highest-confidence prediction of the entire Berlin election.

Current polls show Liberalerna well below the 4% threshold: Indikator Opinion (fieldwork to September 4, 2026): 2.2%; PolitPro election trend (as of September 9, 2026): 2.7%. Neither institute identifies meaningful upward momentum. The party was part of the Tidö coalition but suffered from its image problems. Even with maximum systematic polling error of +1.5 points, Liberalerna would remain below 4.2%. Failing to enter the Riksdag would cost the governing coalition its parliamentary majority.
