TVG is the most popular racebook for Americans for good reason. With a robust online betting platform that’s available in 31 states, TVG makes it exceptionally easy to bet on horses from the comfort of your own home.

In addition to an exceptionally intuitive and well-designed mobile app, TVG offers live streaming of major horse racing events throughout the year.

#2: Twin Spires

Twin Spires is another good choice for betting on the Derby and other horse races. The online site and betting app is owned and operated by Churchill Downs – the official home of the Kentucky Derby. You can read more on our TwinSpires review, for all the latest promos and deposit info.

If you’re new to the world of sports betting, Twin Spires provides lots of educational resources. Some of this basic information is available for free, but you can also pay for detailed statistical reports on a large number of race tracks and past events.

While not as juicy as the TVG new user offer, Twin Spires does provide a sign up bonus worth up to $200. They’ve recently begun expanding into traditional, fixed-odds sports betting in select states where such wagering is legal.

#3: BetAmerica

BetAmerica rounds out our list of the top 5 racebooks for the Kentucky Derby with a simple platform that’s powered by Twin Spires. You’ll find a similar general layout and betting options to those available at their better-known partner site, with less supporting content and fewer bonus offers generally up for grabs.

If you already have an existing sports betting account with BetAmerica, it may be easiest just to jump over to their racebook for pari-mutuel wagering come Derby Day.

Where Can I Bet on the Triple Crown and Other Horse Races?

Online betting on horse racing is legal in most of the United States, with 33 states allowing it.

Here are the states where online horse betting is legal and available in 2021:

It’s worth noting that betting on horse racing is currently legal in far more states than general sports betting. This is because the Professional and Amateur Sports Protection Act – a federal law which banned most sports betting from 1992 to 2018 – made an exception for pari-mutuel wagering on horse racing.

While PASPA has since been repealed, individual states must legalize and set up their own regulatory framework for sports betting.

Just remember – most states allow online wagering on horse racing, even if online sports betting isn’t yet allowed.

Need Some Help Betting on Horses?

Finding the best racebook to bet on the horse races is a must. But even if you’re just hoping to place a quick wager or two for a big race, understanding how horse racing odds work and getting a good sense of different wagering options is worth investing a bit of time.

The horse racing articles in our sports betting guides section are a great place to start.
