Predicted for 20. September 2026
·
Based on: Historical Cycle
All available Berlin polls consistently show the FDP at 3.5% — well below the 5% threshold. Ipsos, the Tagesspiegel election trend, and dawum.de (early September 2026) confirm this figure uniformly. BSW also polls at ~3.8% and is likewise expected to fail. The calibration history is a warning: in the Saxony-Anhalt election (September 6, 2026) the FDP surprisingly achieved 6.4% and cleared the threshold (prediction miss). However, in Berlin there is no upward trend; moreover, the Berlin electorate is structurally less FDP-friendly than that of Saxony-Anhalt. Independent calibration yields approximately 88% probability of failing the threshold.
Data basis for this prediction
- Tagesspiegel/dawum.de Wahltrend Berlin: FDP 3,5 %, BSW 3,8 % (aktuell Anfang Sep 2026)
- Ipsos Berlin-Umfrage: FDP 3,5 %, kein Aufwärtstrend in den letzten 4 Wochen (ipsos.com/de-de, Sep 2026)
- Kalibrierungshistorie: SA-FDP überraschend 6,4 % → Scheitern-Prognose war Miss (bpb.de, 6. Sep 2026)
Verdict: Hit
Die Vorhersage ist eingetreten. Die FDP erhielt bei der Abgeordnetenhauswahl Berlin am 20. September 2026 lediglich 2,5 % der Zweitstimmen – deutlich unter der 5 %-Sperrklausel und sogar noch unterhalb der in Umfragen prognostizierten ~3,5 %. Sie gewann keinen Direktkandidatenwahlkreis und zog damit nicht in das Abgeordnetenhaus ein. Das Ergebnis wurde u. a. durch wahlen-berlin.de (offizielles Berliner Wahlergebnis-Portal) und Wikipedia (2026 Berlin state election) bestätigt. Der Ausgang war klarer als von den Umfragen angedeutet.

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.
