Top Horse Racing Sites Breakdown

While the experience of visiting the track firsthand is hard to beat, there are plenty of ways to bet on the Kentucky Derby with nothing more than your laptop or mobile phone. Here are our top-rated racebooks for 2021:

#1: TVG

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. Add in their lucrative bonus offers for new users and special events, and you’ve got a winning formula for casual Derby fans and dedicated, year-round horse bettors alike.

Ultimately, TVG earns our recommendation as the most immersive online horse betting experience on the market. With live streams and detailed info on hundreds of racetracks throughout the United States and abroad, visiting TVG is the closest you can get to spending an afternoon at the track.


#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.

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 Kentucky Derby 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.
