Democrats Favored to Sweep Congress According to Forecasts and Prediction Markets
Overview
With 35 days remaining before the midterms, forecasting outlets like Decision Desk HQ and prediction markets such as Polymarket and Kalshi indicate that Democrats are now favored to win control of both the House and the Senate. Driven by an eroding political environment for Republicans and public dissatisfaction with economic conditions, the shift reflects potential gains in multiple states and districts previously considered safe.
Key points
- Decision Desk HQ's forecast gives Democrats a 51% chance of sweeping both the House and the Senate.
- Prediction markets like Polymarket and Kalshi place the probability of a Democratic sweep at over 60%.
- The Senate has come into play as a real possibility for Democrats due to a shifting national political environment and sliding Republican support.
