Democrats win the majority in the US Senate at the 2026 Midterm Elections (November 3, 2026) and become the Senate Majority Leader party

Pending ✦ AI-generated prediction Published on 15. July 2026 · Predicted for 3. November 2026 · Based on: Speculative
Probability
38%

Metaculus assigns Republicans 58.9% probability of holding the most Senate seats – implying ≈41% for Democrats. Structural analysis: Republicans currently hold a 53-47 majority and must defend 22 of the 35 contested seats. Democrats need a net gain of four seats. The NYT recently upgraded Alaska from 'Lean Republican' to 'Tossup'. Democrats lead in North Carolina and Maine; Republicans hold narrow advantages in Iowa, Ohio, and Texas. Historical anti-Trump wave effect (the president's party typically loses seats in midterms) could boost chances. Headwind: the Senate map structurally favors Republicans in this specific cycle composition.

Data basis for this prediction
  • Metaculus: Republikaner 58,9 % Senatsmehrheit, Demokraten ≈41 % (Stand Juli 2026)
  • Polymarket: 'Which party will win the Senate in 2026?' (Stand 15. Juli 2026)
  • NYT: Alaska-Senatsrennen zum Tossup eingestuft (270toWin/NYT, Juli 2026)
  • Kalshi 2026 Senate Prediction Markets: Dems führen NC + ME, Rep. Iowa/Ohio/Texas (270toWin, Juli 2026)

Berlin state election (20 September 2026): SPD receives more than 18.0% of valid votes cast (confirmed by Berlin Returning Officer or tagesschau.de by 21 September 2026)

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%.

Berlin Abgeordnetenhaus election (September 20, 2026): FDP falls below 5.0% of valid votes and fails to enter the Abgeordnetenhaus (confirmed by Berlin returning officer or tagesschau.de by September 21, 2026)

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.

Swedish Riksdag election (September 13, 2026): Liberalerna (L) falls below 4.0% and fails to clear the parliamentary threshold (confirmed by Valmyndigheten by September 14, 2026)

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.
