FanDuel Colorado: Legal — Free-Bet Tax Break Ends July 2026

FanDuel Colorado: Legal Since 2020, Taxes Are Changing

FanDuel Colorado has operated as a licensed online sportsbook since May 1, 2020, under a market-access deal tied to a Black Hawk casino rather than a retail shop of its own. Colorado voters authorized the whole industry by the narrowest of margins — Proposition DD passed with barely 51% in November 2019 — and in 2026 the state is in the middle of phasing out the tax break operators like FanDuel used to get on bonus bets.

Legal status in Colorado

Colorado sports betting runs on Proposition DD, the ballot measure voters approved in November 2019 by a margin of roughly 51% to 49% — one of the closer legalization votes in the country. The law lets the Colorado Limited Gaming Control Commission license sportsbooks, but only as an add-on to the state's existing limited-stakes casino industry in Black Hawk, Central City, and Cripple Creek; there is no standalone online license. FanDuel is live under a market-access partnership with a Black Hawk casino operator (Twin River Worldwide Holdings at launch, since rebranded Bally's Corporation), which is how an online-only operator gets a Colorado license without opening its own retail floor. A newer law, HB25-1311, is reshaping the tax side: the cap on deducting promotional free bets from taxable revenue fell to 1% of handle for the first half of 2026 and disappears entirely on July 1, 2026.

State gambling authority: Colorado Division of Gaming, operating under the Colorado Limited Gaming Control Commission within the Department of Revenue.

FanDuel Colorado has run as a licensed online sportsbook since May 1, 2020, one of the first five states where FanDuel went live after Colorado voters authorized the industry. It got there in an unusual way: there was no clean yes-or-no vote on sports betting by itself, and there is still no FanDuel retail sportsbook anywhere in the state.

Is FanDuel Legal in Colorado?

Yes, but the law it runs on barely passed. Proposition DD, the November 2019 ballot measure that legalized sports betting statewide, cleared by roughly 51% to 49% — one of the narrowest sports-betting votes of the entire 2018–2026 expansion era. It didn't create a standalone online license. Instead it bolted mobile and retail sports wagering onto Colorado's existing limited-stakes casino framework, which confines licensed gaming to three old mining towns: Black Hawk, Central City, and Cripple Creek. An online-only operator like FanDuel gets in through a market-access partnership with one of those casinos rather than a license to stand alone.

FanDuel's Colorado license: market access through a Black Hawk casino operator — Twin River Worldwide Holdings at the May 2020 launch, since rebranded Bally's Corporation. Retail sportsbook: none; FanDuel never opened a physical counter in Colorado. Regulator: Colorado Division of Gaming, under the Limited Gaming Control Commission.

The Free-Bet Tax Break Is Disappearing in 2026

Colorado taxes sports betting at 10% of net proceeds, with the money earmarked for water projects through the Colorado Water Plan — the detail that helped Prop DD squeak through in 2019. For years, operators including FanDuel could shrink that taxable number by deducting the value of promotional bonus bets they handed out. That break is being phased out. Under HB25-1311, signed by Governor Jared Polis in May 2025, the deduction cap fell to 2% of handle for the back half of 2025, drops to 1% for January through June 2026, and disappears completely on July 1, 2026. The state's own fiscal note projected roughly $12.9 million in additional tax revenue from the change in its first full year.

None of that changes what a Colorado bettor sees at sign-up — FanDuel's bonus-bet structure is a national offer, not a state-specific one. What changes is how much of that bonus value FanDuel gets to write off its Colorado tax bill, which is a regulator-and-revenue story, not a player-facing one.

Is FanDuel Safe in Colorado?

Yes, in the sense that matters for a bettor: the Colorado Division of Gaming, operating under the Limited Gaming Control Commission, licenses and audits FanDuel the same way it licenses every retail casino floor in Black Hawk, Central City, and Cripple Creek. Geolocation enforces the state line before a wager is accepted, and the master-licensee structure means FanDuel's Colorado operation is tied to a named, regulated casino partner — not a free-floating app with no local accountability.

No FanDuel Casino Here

Proposition DD only ever authorized sports betting. Colorado has no legal online casino market of any kind, for any brand, so this isn't a FanDuel-specific gap. Slots and table games stay confined to the three limited-stakes mountain towns in person. FanDuel Casino nationally exists in just five states — Connecticut, Michigan, New Jersey, Pennsylvania, West Virginia — and Colorado misses that list for a structural reason, not an oversight.

Who It Fits

Adults 21+ in Colorado get a fully licensed FanDuel sportsbook with six years of track record and a named regulator behind it. The tax fight over free-bet deductions is a state-revenue story worth knowing, not a reason to doubt the book's legitimacy. Treat every wager as entertainment spending, not income.

FanDuel Colorado — Frequently Asked Questions

Is FanDuel legal in Colorado?

Yes. FanDuel has held a Colorado sports betting license since the market launched on May 1, 2020, under Proposition DD, the November 2019 ballot measure that authorized sports wagering statewide. It operates through a market-access deal with a Black Hawk casino rather than a license of its own storefront.

Is FanDuel safe to use in Colorado?

Yes. FanDuel is overseen by the Colorado Division of Gaming under the Limited Gaming Control Commission, the same regulator that licenses every retail casino in Black Hawk, Central City, and Cripple Creek. Geolocation confirms a bettor is physically in Colorado before any wager is accepted.

Why does FanDuel Colorado need a casino partner if it only operates online?

Colorado never created a standalone online sportsbook license — Proposition DD attached mobile betting rights to the state's existing limited-stakes casino licenses in three mountain towns. FanDuel's path in is a market-access agreement with a Black Hawk casino operator (Twin River at launch, now Bally's Corporation), the same structure DraftKings and other online books use.

Is the FanDuel bonus bet offer changing in Colorado?

Not the offer itself, but the tax treatment behind it is. Under HB25-1311, signed in May 2025, the cap on operators deducting promotional free bets from taxable sports betting revenue dropped to 1% of handle for January through June 2026 and ends completely on July 1, 2026. That raises FanDuel's effective Colorado tax bill; it does not change what a bettor is offered.

Does FanDuel have an online casino in Colorado?

No. Proposition DD authorized sports betting only — Colorado has no legal online casino market at all, in any brand. Retail slot and table games stay confined to the limited-stakes casino floors in Black Hawk, Central City, and Cripple Creek. FanDuel Casino nationally runs in just five states (Connecticut, Michigan, New Jersey, Pennsylvania, West Virginia), and Colorado is not one of them for either reason.

Where does Colorado sports betting tax money go?

To water projects. Proposition DD set a 10% tax on net sports betting proceeds, with the revenue earmarked for the Colorado Water Plan and distributed as grants by the Colorado Water Conservation Board — the same pitch that helped the measure narrowly pass in 2019.
