Who will control the Senate?
Slight lean to Yes: fresh polling and simulations favor Democrats, but the Senate remains unresolved. The 75% market already reflects much of that edge, so the move is modest.
Analysis
As of Nov. 2, 2026, Democrats have not yet been confirmed to control the Senate, and several races remain uncalled. Fresh polling and modeling favor Democrats, especially in Michigan, Texas, Maine, Ohio, and Kansas.
That said, the market already prices a strong Democratic chance, and the decisive issue is final control, not polling. Republicans still have a path if late counts and close races break their way.
Arguments
For
- Democrats are ahead in several key Republican-held targets.
- Simulations currently favor a Democratic Senate majority.
Against
- The result is not yet final on Nov. 2.
- Several races are within normal polling error and can reverse.
Key drivers
- Democratic leads in multiple battleground Senate races.
- Final uncalled seats still leave Republicans a live path.
Risk factors
- Polling error could swing several close seats at once.
- Control depends on certification of the final Senate balance.
Scenarios
Best case
If the leading Democratic polls hold through final counts this week, Yes rises to about 85%.
Most likely
Most likely Democrats narrowly secure control, with Yes around 77%.
Worst case
If Republicans win enough late-deciding races this week, Yes falls to about 45%.
