Predicted for 20. September 2026
·
Based on: Statistical Pattern
All final polls show a genuine three-way race: Die Linke at 20.7–23% (BerlinTREND/Infratest dimap, PolitPro, as of 18–19 Sep 2026) narrowly ahead of CDU (20–21%) and AfD (17–18.9%). In 5 of 6 latest polls Die Linke ranks first, but always within margin of error vs CDU. Greens (15–16%), SPD (10–12%), BSW (~3–4%), FDP (~3%) trail. No prediction markets for Berlin state elections available. The ~42% reflects the genuine three-way contest: with base odds ~25–30% each for Linke, CDU, AfD to top, Die Linke's polling lead gives a slight edge.

All final polls (Infratest dimap, INSA, as of 17–18 Sep 2026) put the AfD at 37–38% in MV, more than two percentage points above the 35.0% threshold. SPD under Minister-President Schwesig follows at 33–34%; CDU and Die Linke each at ~7%. The gap between poll mean (~37.5%) and threshold (35%) exceeds the typical polling-error standard deviation (~2pp), justifying high confidence. No prediction markets available; 78% accounts for a residual SPD late-mobilisation risk.

After the 3rd Security Council straw poll on September 18, 2026, Rebeca Grynspan (Costa Rica, former UNCTAD Secretary-General) and Carolyn Rodrigues-Birkett (Guyana) lead 8 candidates. UNGA 81 High-Level Week (Sept 22–27) frames the 4th straw poll; Guterres' term ends December 31, 2026. Grynspan has the broadest backing (G77+China) but faces P5 veto risk from Russia or China. No Polymarket market found; probability based on straw-poll lead minus P5 veto risk.

Polymarket prices Democrat House majority at 88–90.5% (as of September 19, 2026). Generic Congressional Ballot shows Democrats leading D+7 to D+12; Trump's approval sits around 38% per aggregators. Historically the president's party loses ~26 House seats in midterms — current factors (Iran war, economy, unpopularity) amplify this trend significantly. Democrats need a net gain of ~5 seats for a majority of 218. I calibrate at 84% (slight discount to Polymarket's 88–90.5% for long-horizon uncertainty). The existing open prediction covers only the Senate — the House is a separate event, no duplicate.
