Prediction Markets
What traders are actually paying for each outcome on Polymarket. A contract settles at $1 if it happens, so its price reads directly as an implied probability. These are prices, not a forecast — they move all day, they can be wrong, and they are worth reading alongside polls and race ratings rather than instead of them.

Control of each chamber
| Market | Democratic | Republican | Split |
|---|---|---|---|
| Which party wins the 2028 presidency | 67% | 34% | |
| Which party wins the Senate in 2026 | 66% | 35% | |
| Which party wins the House in 2026 | 93% | 8% |
Each party trades as its own contract rather than as a share of one pool, so a row’s two prices are quoted independently and need not total 100%.
2026 governor races
There is no market on who holds a majority of governorships, so this is counted from the individual state races: of the 34 that Polymarket prices, the Democrats lead in 19 and the Republicans in 15.
The six closest shown. See all 34 priced races. No party-readable market for California.
