I correctly called the #Bundestagswahl2025 back in December.

My model wasn’t perfect, but I did predict that a grand coalition (CDU/CSU + SPD) was the most likely outcome—more likely than the polls suggested. Here’s how my predictions held up: 🧵⬇️

If you look at the different party trajectories from the past 3 months some obvious trends stick out:
- The ascent of the #AFD, #DieLinke, and #DieGruenen
- How little both the #CDUCSU and the #SPD moved the needle during their campaigns
- #BSW was always gonna come down according to my model

Final prediction for the #Bundestagswahl2025 !

The top takeaways:
- A #CDUCSU and #SPD grand coalition will be possible
- The #AFD will have their best result ever but underperform their polls
- #DieLinke will reeenter parliament
- #FDP's reentry is on a knife's edge.

New predictions for the #Bundestagswahl2025

#FDP now more solidly before 5% in my forecast but well within the margin of error.

New predictions on vorcast.org! #DieLinke continues its climb, looking more and more like a safe bet for reentry of parliament after the #Bundestagswahl2025

New predictions up for the #Bundestagswahl2025

As designed, the polls and my model are converging. Biggest discrepancy between them remains the #AFD, followed by the #SPD.

1 week until the #Bundestagswahl2025. The most important takeaways from my latest predictions:

1. Coalition between #CDUCSU and #SPD still possible
2. #DieLinke likely above 5%
3. #FDP's reentry into the Bunedstag on knife's edge
4. #BSW not likely to enter the Bundestag

Model update with the latest two polls. #DieLinke continues to gain some ground, not much movement for the other parties.

My model's predictions differ from @zeit.de now. According to them a three party coalition is most likely.
February 13, 2025 at 5:44 PM
With the latest round of polls released a grand coalition between the #SPD and #CDUCSU is still possible (according to my model). It’s going to be a very close #Bundestagswahl2025.

Also, #DieLinke is looking more and more likely to enter the Bundestag.
February 13, 2025 at 5:42 PM
The #Bundestagswahl2025 is 2 weeks away so there's not much difference between the Vorcast Polling Average and the Vorcast Model anymore..but that difference is important.

According to my model, a grand coalition between the #CDUCSU and the #SPD is still possible, barely.
February 9, 2025 at 6:24 PM
With 2.5 weeks to go until the #Bundestagswahl, these things are still possible:

- #FDP, #DieLinke & #BSW all have a shot at entering the Bundestag

- The #SPD could end up in arm's reach to the #AFD (unlikely according to my model, impossible according to the polls)

First predictions up since last week's drama in the #Bundestagswahl2025.

Out of the two released polls, one was bad for the #CDUCSU but it's too early to detect any major shifts.
February 4, 2025 at 2:54 PM
Durch diese Umfrage verliert die #CDUCSU weiter leicht in meiner Vorhersage auf vorcast.org

Die #Linke kann sich langsam wieder mehr Hoffnung auf einen Einzug haben, laut meinem Modell steht sie bei 4.7%.

New predictions up on vorcast.org

Taking the long-term view: Only the #AFD and #DieGruenen have changed significantly in my forecast.

No other party has managed to move the needle. Also no effect in the polls or my model from @_FriedrichMerz's immigration push.

Die beste Umfrage für die #AFD seit die Ampel auseinander gebrochen ist.

Auch in meinem Modell legt die Partei weiter zu, aber ist (noch) unter 20% 👇
vorcast.org
January 29, 2025 at 10:25 AM
Die #SPD kann durch mein Modell noch ein wenig Hoffnung schöpfen, da sind sie bei knappen 18%. Allerdings schwindet die Wahrscheinlichkeit eines besseren Abschneidens da auch mit jeder schlechten Umfrage die veröffentlicht wird.
January 27, 2025 at 7:05 PM
Bei den #Gruenen sieht es ähnlich aus (1.5%). Das hat auch damit zu tun, dass die Partei oft schlechter als ihre Umfragewerte abschneidet.
January 27, 2025 at 7:05 PM
Am meisten driften mein Modell und die Umfragen (noch) bei der #AFD auseinander, nämlich 2.7%.

Bei meinem Modell spielen zusätzlich zu den Umfragen auch noch Langzeitrends und wirtschaftliche Faktoren eine Rolle, doch deren Gewicht nimmt ab je näher wir am Wahltag sind.
January 27, 2025 at 7:05 PM
Ab jetzt gibt es Vorcast auch auf deutsch 🇩🇪 #Bundestagswahl2025

In meinem neuesten Post erkläre ich warum sich mein Modell mit den Umfragen nicht verträgt und warum ich langsam nervös werde: www.vorcast.org/mein-modell-...

It's only by 0.5% but the #AFD has overtaken the #SPD in my forecast for the #Bundestagswahl2025. This is the result of the fundamentals weight decreasing in my models as we get closer to the election.

New predictions up for the #Bundestagswahl2025

The #SPD and #AFD are neck to neck now in my forecast. Despite the polls, the #SPD is still predicted to come out on top of the #AFD but just barely.

Allensbach war bei der letzten Bundestagswahl das genaueste Umfrageinstitut.

In meinem Modell haben deren Umfragen deswegen das höchste Gewicht. Mehr Infos hier: vorcast.org

Lastly, I go into why even a big miss from my model might still provide us with some insights into how the German electorate has changed.
January 22, 2025 at 7:04 PM
For all of the smaller parties, the #FDP, #BSW and #DieLinke , this election will be existential in that they are all really close to 5%. This is the threshhold that smaller parties have to reach in order to remain (or enter) the Bundestag.
