Two Polymarkets
- polymarket.com is the international site. US visitors see a notice that trading is blocked.
- Polymarket US is a separate CFTC-regulated exchange run by QCX LLC, with its own listings and prices.
- Many sites quote polymarket.com prices because the data is public. Our NBA guides use Polymarket US prices, the ones US traders can actually get.
State by state
Both US exchanges are federally regulated, but some states argue sports contracts fall under state gaming law, and cases are ongoing. Each app checks your location and shows what you can trade. Sign-up offers can also vary by state.
Kalshi or Polymarket US

Prices differ by a cent or more on most markets. NBA MARKET shows both side by side for every game, and the champion and MVP guides compare the futures.
