Horse race betting became Colorado’s first legalized form of gambling decades. A measure passed through the Colorado General Assembly approved horse racing facilities to operate in the state, as well as pari-mutuel betting on in-state races. It took four more decades to make Colorado online horse betting a reality.

A 1948 law created the Colorado Racing Commission as the governing body to oversee the state’s horse racing industry. A second regulatory agency, the Division of Racing Events, began operations in 1983. Colorado’s first live race ran in 1949.

In 1991, Senate Bill 91-99 legalized interstate simulcasting of races and off-track betting facilities. This expansion of Colorado’s horse racing laws allowed for legal online horse race betting within state borders.

TVG Horse Racing and BetAmerica both offer legal online horse racing betting in Colorado.

What Types Of Bonuses Are Available For Online Horse Betting In Colorado?

Deposit Match Bonuses

Players across all forms of legal online gambling should be familiar with deposit match bonuses. Many different platforms offer this kind of bonus, including online casinos, sports betting, and horse racing sites.

Deposit match bonuses offer bonus money matching a certain percentage of a player deposit. These offers usually apply to the first deposit made on an online gambling platform.

BetAmerica offers a 100% deposit match bonus up to $100 for Colorado bettors that sign up for a new account.

The BetAmerica deposit match bonus requires a 10x playthrough to unlock the full bonus. For example, a $100 deposit is eligible for up to a $100 total bonus, but $1,000 must be wagered on BetAmercia to unlock the full $100 bonus.

Sign-Up Bonus

Sign-up bonuses offer new players one of the easiest ways to earn bonus funds on an online horse race betting site. These kinds of offers award bonus money just for registering for a new account.

The bonus funds awarded through a sign-up bonus usually come in the form of betting credits. These credits must be used to wager on the site and can’t be directly withdrawn.

Neither of Colorado’s legal mobile horse race betting platforms currently offer a free sign-up bonus, but that could change in the future.

Risk-Free Bets

Risk-free bets offer a rebate on a player’s first bet on an online horse race betting platform, if the bet results in a loss. This kind of offer usually applies to a single bet made after the initial deposit.

New bettors that register for a TVG account can enjoy their first bet risk-free, up to $200. For example, if a new player makes a $200 wager after the first deposit, and the bet results in a loss, TVG refunds $200 on the lost bet.

Who Regulates Horse Racing In Colorado?

A pair of regulatory agencies oversee Colorado’s legal horse racing industry. These agencies operate under the umbrella of the Colorado Department of Revenue.

The 1948 legislation that legalized horse racing in Colorado mandated the formation of the Colorado Racing Commission. The Colorado Racing Commission regulated the state’s retail horse racing industry from 1948-1983.

The creation of the Division of Racing Events in 1983 added a second governing body to regulate state horse racing operations.

The Colorado Racing Commission and Division of Racing Events regulate both retail, OTB and online horse race betting in Colorado. TVG and BetAmerica are both approved and regulated by Colorado’s pair of regulatory agencies.

How Safe Is Online Horse Race Betting In Colorado?

Legal mobile horse race betting platforms offer secure wagering, protection of personal information, and prompt payouts.

The Colorado Racing Commission and Division of Racing Events are government agencies that regulate Colorado’s legal horse race betting industry. The oversight of these agencies ensures a legal and safe wagering experience on Colorado’s legal mobile horse racing platforms.

TVG and BetAmerica are currently the only two legal and approved online horse race betting platforms in Colorado. Any other site offering online horse race betting in Colorado is operating illegally.

Offshore or illegal online gambling platforms do not offer the same level of security as legal, state-regulated sites. The sites operate illegally in the US, and as such using these platforms carries potential legal consequences for players.

Money deposited at an offshore gambling site could be lost forever, as these platforms operate outside US regulations.

What Races Can You Bet On In Colorado?

Popular Horse Racing Events In Colorado

Arapahoe Park operates as Colorado’s lone live racetrack and hosts several popular events each summer.

The biggest race of the year, the Mile High Futurity, always runs as the final event of the year on the Arapahoe Park schedule. Other popular events at Arapahoe Park include the Cherry Creek Futurity, Mile High Derby, and Arapahoe Park Classic.

Important American And International Races

American Triple Crown Races

The biggest and most famous horse race in the US, the Kentucky Derby draws the largest wagering pool of any annual US race. The Kentucky Derby takes place each May at Churchill Downs in Louisville, Kentucky, and is the first leg of the US Triple Crown.

The Preakness Stakes generally follows two weeks after the Kentucky Derby, emanating from Pimlico Race Course in Baltimore, Maryland. The final leg of the Triple Crown, the Belmont Stakes, takes place annually in June from Belmont Park in New York.

Colorado bettors can legally wager on all three Triple Crown races on TVG and BetAmerica.

Does Colorado Have OTB Facilities?

While Colorado hosts just one live racetrack, numerous off-track betting (OTB) parlors offer horse race wagering on events across the country.

A total of 11 standalone OTB parlors operate in Colorado. Arapahoe Park, Colorado’s lone retail racetrack, also offers simulcast horse race betting.

The passage of Senate Bill 91-99 in 1991 legalized OTB facilities and simulcast interstate horse race wagering, bringing forth Colorado’s current landscape of OTB parlors.

The Interstate Horseracing Act of 1978 legalized OTB parlors nationwide and outlined the financial partnership between OTB facilities and retail horse racetracks. US-based OTB parlors must share revenue with retail racetracks, the states in which they operate, and owners of participating racehorses.

Colorado’s 11 OTB facilities are spread out across the state. These parlors include Denver-area facilities like Celtic on Market and Softball County.

Aurora, Colorado Springs, Fort Collins, Littleton, and Pueblo all host OTB parlors as well.
