Based on: Ongoing Event
In the Berlin Abgeordnetenhaus election on September 20, 2026, Die Linke receives the most votes of any party. Polymarket assigns 67% win probability to Die Linke (total volume ~$3.7M, as of September 14, 2026). Current polls: Linke 20.7%, CDU 19.9%, AfD 17.8%, Greens 16.1%, SPD 12.1%. The lead over CDU is only ~0.8 percentage points — within the margin of error. Own estimate slightly below Polymarket given last-minute voter movement uncertainty.

Current polls (Forsa/Infratest, 13 September 2026) put the Berlin FDP at only 3.4% — well below the 5% threshold. The FDP already failed in Berlin in 2023 with 4.6%. Following the collapse of the federal coalition, the FDP's exit from the Bundestag in 2025, and the absence of prominent Berlin state politicians, a swing from 3.4% to above 5.0% within one week is barely realistic. No prediction market (Polymarket, Metaculus) directly trades this question, but the 1.6 pp polling gap and historical underperformance in Berlin support a probability of ~90%.

PolitPro's September 13 trend shows Berlin SPD at 12.1% — a historic low. Even accounting for ±3pp polling error, exceeding 14% would require a substantial over-performance. National drag from the 2025 coalition collapse, CDU chancellorship, and Die Linke's strength in Berlin's urban left flank explain the decline. No direct prediction market; calibrated via polls only.

Kalshi prices the probability of the Republican candidate winning Iowa's 2026 Senate race at approximately 61%; Polymarket confirms a similar assessment. Incumbent Joni Ernst (Republican, senator since 2015) is running for her third term in Iowa. Iowa ranks among the most structurally Republican-leaning swing states of recent election cycles: Donald Trump carried Iowa by ~13 points in 2024. Even in a national Democratic Midterm wave scenario (Polymarket: 'Democratic Sweep' = 53%), Iowa remains extremely costly and logistically challenging terrain for Democrats. Crucially, Democrats can win the Senate majority without Iowa — by flipping Ohio (52% Democratic, Kalshi) and Texas (51% Democratic, Kalshi) — drawing resources away from Iowa. Ernst's moderate profile on farm subsidies and veterans' issues shields her from significant intra-state backlash.
