Polymarket is back in the US
For years, Polymarket's main site was off-limits to American users. That changed in January 2026, when Polymarket US launched as a CFTC-regulated exchange with its own clearing house. It started with sports markets and has since added politics, including the midterms.
The US app and the international site at polymarket.com are run separately. Prices can differ slightly between the two, and not every market on the international site is necessarily listed in the US app, so check the app to see what's live for your account.
Polymarket US also has its own midterms page at polymarket.us/midterms, with a state-by-state view of the races it lists. Individual Senate races trade there too: Polymarket US had handled about $4.7 million on the Maine Senate race by October 22.
The Polymarket Midterms Hub
In September 2026, Polymarket launched a Midterms Hub that brings its election markets into one place. It includes:
- An interactive map that zooms from the national picture down to single states and districts.
- A key races view covering the most competitive contests.
- Balance-of-power markets on control of Congress.
- Live vote counts on election night, shown next to market prices so you can watch the odds react as results come in.

What does Polymarket say about the midterms?

- Ohio Senate: Sherrod Brown (D) about 72%, Jon Husted (R) about 29% (October 30)
- Maine Senate: Troy Jackson (D) about 67%, Susan Collins (R) about 33% (October 30)

How Polymarket pricing works
Every Polymarket share trades between $0 and $1, and the price reflects the chance the market gives that outcome. A winning share pays $1 and a losing share pays nothing.
Say you buy 50 shares of "Democrats win the Senate" at 66¢. That costs $33. If Democrats win control, your shares are worth $50, a profit of $17. If they don't, the shares expire worthless. You can also sell before the result if the price moves your way.
Polymarket runs on a peer-to-peer order book, so you're trading with other users rather than against the house. You can buy at the current price or set your own price and wait for another trader to fill it.

Polymarket US is open to adults in eligible states, with identity checks when you sign up. The promo code CHECK offer isn't available in Nevada. For state-by-state details, see our guide to where you can bet on the 2026 midterms near you.
