Colorado sports betting in 2026: what Nuggets fans can use

Is sports betting legal in Colorado? Yes. Adults 21 and over can use licensed sportsbook apps anywhere in the state and retail sportsbooks at casinos in Black Hawk, Central City and Cripple Creek, and have been able to since May 1, 2020. This year the state tightened the rules on those books, and prediction markets have grown up alongside them under federal oversight. Here is where things stand for Nuggets fans as of Nov. 4.

How Colorado got here

The Legislature passed HB19-1327 in 2019, and Gov. Jared Polis signed it that May. Because it created a new tax, it needed voters' approval under the Taxpayer's Bill of Rights, and in November 2019 they gave it, narrowly, as Proposition DD. The law took sports betting out of the criminal code and set a 10% tax on the books' net proceeds, most of it for the state water plan. In 2024 voters approved Proposition JJ by about 76% to 24%, according to Ballotpedia, letting the state keep revenue above the original $29 million a year instead of refunding it.

The Colorado Division of Gaming licenses and polices the books, under rules set by the Limited Gaming Control Commission. Every online sportsbook operates under the license of one of the state's casinos.

Who is licensed

The Division of Gaming's list of online operators includes every sportsbook on our board: DraftKings, FanDuel, BetMGM, bet365, BetRivers, Hard Rock Bet, theScore Bet and Fanatics. Also licensed are Caesars, Circa Sports, Bally Bet and BetMonarch. Sporttrade, a state-licensed betting exchange, is still on the list but stopped taking wagers in Colorado on May 25, according to trade-press reports. The Division's separate retail list shows ten casino sportsbooks.

That means the sportsbook rows on the board are prices a fan standing in Colorado can actually take, which is not true in every NBA market.

What changed in 2026

Two laws changed the books' business this year.

SB26-131, which Polis signed in early June and which took effect Aug. 12, is the biggest change since launch. Licensed online books can no longer accept credit card deposits, directly or through a card-linked e-wallet, and can take no more than six deposits from one customer in a gaming day. They cannot send texts or push notifications that solicit bets or deposits, and neither they nor their marketing affiliates can aim ads at people under 21 or run them in media whose audience is mostly under 21. The Limited Gaming Control Commission enforces it, with penalties of up to $25,000. A proposed ban on player props was dropped before passage, RotoWire reported, so Colorado apps still offer them. FanDuel and DraftKings opposed the bill, arguing it would push customers toward unregulated markets, Colorado Politics reported.

HB25-1311, passed in 2025, finished phasing out the books' tax deduction for free bets: since July 1, 2026 they can deduct none of it, so more of their revenue is taxed.

Prediction markets: open, and argued over

Colorado has not ordered prediction markets out of the state or sued them. When Colorado Public Radio asked about Kalshi in May, the Division of Gaming declined to comment beyond saying it was monitoring the court cases elsewhere, KUNC reported. The same report noted that Kalshi pays no Colorado sports betting tax and is not bound by the state's problem-gambling rules, because it is regulated as a federal exchange. Attorney General Phil Weiser joined a coalition of other state attorneys general this spring in telling the CFTC that sports event contracts should fall under state law. That is advocacy in Washington, not enforcement in Colorado, and so far nothing has changed for a trader in the state.

The result for a Nuggets fan: Novig, Kalshi and Polymarket US are available in Colorado today, alongside the licensed books. Novig is a CFTC-regulated exchange where you take a position on a game at a price set by other traders, and it is live in 47 states, every state except Arizona, Michigan and Nevada. That matters on the road: when the Nuggets visit Detroit on Nov. 30, Novig will not work in Michigan. SB26-131's deposit and messaging limits apply to the state-licensed sportsbooks, not to federally regulated exchanges.

What a Nuggets fan can use tonight

Every Nuggets game is priced on the board, Novig first, alongside the sportsbooks and the other exchanges. The Colorado page prices this week's games at the venues a fan in the state can open, and it carries the date we last checked the law. Prediction markets vs sportsbooks explains how the two kinds of venue arrive at a price, and how to read the Nuggets board works through the numbers.
