Quick answer: Polls and forecasts favor Democrats to win the House in the November 3 midterms, while control of the Senate is much closer. Forecasts vary a lot, so treat any single number with caution.
What Is on the Ballot
All 435 House seats are up for election on Tuesday, November 3, 2026, along with 35 of the 100 Senate seats, many governorships and local races.
The House: Democrats Are Favored
Several national polls show Democrats ahead on the generic congressional ballot. One forecast model using polls through October 18 put the Democratic lead at about seven points, while AP-NORC data cited by Kalshi’s news site showed a lead near nine. Forecasters and prediction markets generally put Democratic chances of winning the House between 85 and 90 percent. Historically the president’s party tends to lose seats in midterms, and President Trump’s approval ratings in several trackers are in the high 30s.
The Senate: A Much Closer Fight
Republicans hold a 53-47 majority, so Democrats need a net gain of four seats. Estimates of Democratic chances range from about one in three to nearly two in three depending on the model or market. That spread reflects real uncertainty, not a firm prediction.
Key Issues
Inflation and the cost of living have been described as top concerns for voters. Redistricting fights in several states and recent Supreme Court rulings on election maps have also shaped the landscape. Read our Supreme Court term review for background.
How to Read the Numbers
- Polls are snapshots with margins of error, and they can miss in either direction.
- Forecast models and betting markets estimate probabilities, not results.
- Turnout can swing close races and is hard to measure in advance.
