Based on: Historical Cycle
Berlin Greens poll consistently at 15–16%: Forschungsgruppe Wahlen (Sept 11) 16%, Infratest dimap (Sept 10) 16%, INSA (Sept 4) 15%, Civey (Aug 31) 15%; dawum aggregate 15.6%. Polymarket assigns ~3% probability to the Greens winning outright — they hold their base as a stable fifth party in a tight five-way race. Falling below 14% would require a >1.6-point polling miss.
Data basis for this prediction
- Forschungsgruppe Wahlen: Grüne 16% Berlin (11.09.2026)
- Infratest dimap: Grüne 16% Berlin (10.09.2026)
- INSA: Grüne 15% Berlin (04.09.2026)
- dawum.de Berlin Aggregat: 15,6% / Polymarket Berlin State Election (11.09.2026)
Verdict: Hit
Die Grünen erhielten bei der Abgeordnetenhauswahl Berlin am 20.09.2026 laut amtlichem Ergebnis 14,29% der Zweitstimmen (Quelle: wahlen-berlin.de, Wikipedia: 2026 Berlin state election). Damit wurde die Schwelle von 14,0% knapp, aber eindeutig überschritten. Das Ergebnis lag jedoch deutlich unter dem Umfragemittel von ~15–16%: Die Grünen verloren 4,1 Prozentpunkte gegenüber der Wahl 2023. Die Vorhersage gilt dennoch als erfüllt, da das einzige Kriterium >14,0% war.

Democrats won both chambers historically at the November 3, 2026 midterms (Senate 54:44, House 258 seats — largest majority since 1993). Trump's disapproval rating stands at 62% (FiveThirtyEight, Nov 2026). Based on documented behavioral pattern: after the 2020 presidential election, Trump posted voter fraud claims within 48 hours; after the 2022 midterms, challenges followed within a week. Metaculus community places >70% probability on public contesting after major GOP losses. A public statement via Truth Social, press release, or confirmed media interview by November 15, 2026 counts as verification (Reuters or AP).

Ukrainian, US, and Russian negotiators convene November 10–11 in Abu Dhabi. Russia conducted large-scale long-range strikes on Ukrainian energy infrastructure and logistics hubs on November 3–4; Ukraine responded with drone strikes on the Ryazan refinery. Positions on territory and security guarantees remain far apart. No Polymarket or Kalshi market covers this specific event; historical base rate for failure of comparable trilateral talks: >80%.

Spain holds a general election on 29 November 2026. Polymarket prices Feijóo as next PM at 85%, Kalshi at 82% — both serve as anchors. A separate Polymarket market gives PP+Vox a 92% probability of a joint majority (>176/350 seats). Current polls (Sondaxe) show PP at 29.2% narrowly ahead of PSOE (26.9%); Vox is tracking slightly higher. Feijóo failed to form a government in 2023, but market odds reflect the lesson learned: PP+Vox is now seen as stable enough. No deviation from market anchor warranted.
