Colorado has one of the most open markets in the country, with apps licensed through its casino towns.

Sportsbooks in Colorado

On vigged, DraftKings, FanDuel, BetMGM, Caesars Sportsbook, Hard Rock Bet, theScore Bet and Circa Sports are ranked for Colorado: their prices are the ones best price, +EV and arbitrage use when your state is set to CO. Kalshi joins them as a book (on by default) on a side with $2,000 available at its price.

Offshore sites such as Bovada are not licensed in Colorado or any other state: no regulator holds your deposits or settles disputes. vigged shows offshore prices unranked and never links to them.

Prediction markets: Kalshi and Polymarket US

Kalshi offers sports event contracts in Colorado to adults 18+. It is a federally regulated exchange (CFTC), not a state-licensed sportsbook, which is why it can operate alongside the sportsbooks.

Polymarket US, the CFTC-regulated app Polymarket launched in late 2025, lists Colorado as eligible; access is opening by waitlist. It is a separate order book from Polymarket’s international site, which does not serve US users.

How they differ from a sportsbook: you buy a contract that pays $1 if the outcome happens, priced in cents (58¢ is a 58% chance), from other traders rather than a bookmaker. Fees take the place of vig, the minimum age is 18 rather than 21, and the legal fight over sports contracts is still moving.
