Predicted for 3. November 2026
·
Based on: Historical Cycle
Polymarket prices Democrats at 59% for Senate control as of 15 September 2026 ($4.5M trading volume). Nate Silver's model gives Democrats 56.5%. Republicans hold a 53-47 majority; Dems need 4 net gains. Key vulnerable Republican seats: North Carolina (Roy Cooper leading), Iowa, Ohio, Texas (structurally tough). With Trump's approval underwater and Democrats +8 on the generic ballot, the market consensus of ~59% for a Democratic Senate flip is well-calibrated. Cassandra applies a marginal discount to 58%.

Current polls (Politpro.eu, as of ca. September 14, 2026) show the AfD at 17.9% in Berlin — clearly above the 16.5% threshold. A drop of more than 1.4 percentage points from current polls would be required to miss the prediction. The AfD ranks third behind Die Linke (19.8%) and CDU (19.6%). No Berlin-specific Polymarket markets available; calibration based on Politpro.eu polling data. Note: the open MV prediction (AfD >30%) is separate; in Berlin the party is weaker but firmly double-digit.

The 2021 State Duma election recorded an official turnout of 51.72% — a figure the Kremlin viewed as critically low. Since then, 3-day voting has been institutionalised, e-voting (u-Golosovaniye) rolled out nationwide, and intensive loyalty campaigns run under the framing of the Ukraine war. The 2024 presidential election officially hit 77.4%. Parliamentary elections historically generate less mobilisation than presidential contests; a reported figure between 60% and 70% appears realistic. Polymarket and Metaculus carry no direct quotes. Estimate based on historical Russian election data (CEC 2021, Reuters 2024, OSCE/ODIHR reports). No contradiction with open predictions on party vote shares.

President Vučić dissolved parliament in September 2026 and called snap elections for 25 October 2026. SNS won the 2023 snap elections with 46.2%. Government-aligned polls (Faktor Plus, spring 2026) show the party at ~46%; independent institute CRTA estimates support at 35.7% (July 2026) — the first time since July 2010 that an opposition-friendly aggregate has led. Polymarket prices Vučić at 66.3% to become next Prime Minister. SNS controls state media and administrative resources, conferring structural campaign advantages; however, student protests and a strengthening opposition coalition are mounting pressure. Even if the independent CRTA estimate proves more accurate than party-aligned polls, a result above 40% remains likely — SNS historically stays above this threshold even under stress.
