The “sport of kings” is steeped in tradition, but the modernization of betting has ushered in a new crop of fans and bettors who are looking to become horse racing betting experts. If you’re reading this page, there’s a good chance that you are looking for ways to engage and interact with horse racing betting sites. We can help.

With the Belmont Stakes on deck, there’s still never been a better time to register with an online horse racing betting site. Read our round-up of the best online horse racing betting sites available in your area.

Where to bet on horse racing


Not all sportsbooks offer horse racing odds. However, you can turn to several legal horse racing specialist betting sites to meet your needs. Here are the best Preakness Stakes betting sites available in your area:


Horse racing’s popularity in Canada — and subsequent revenues — have soared to historic highs in recent years. The industry accounts for 50,000 jobs and $5.7 billion (Woodbine Communications) in economic activity across Canada. We’ve identified the top betting sites for Canadians looking to place bets on the Preakness and upcoming races:

Types of horse racing for online betting

You need to know a little bit about how to bet on horse racing and its betting intricacies before you can get started. Good news: This is the best place to start. First, let’s take a look at the three major types of horse racing.

Thoroughbred racing

Surely even the uninitiated are familiar with the term thoroughbreds. The most common form of horse racing features jockeys astride of thoroughbreds running on flat surfaces. Thoroughbreds can run on dirt or grass tracks, with distances ranging from 5/8 of a mile to 1 1⁄2 miles, although there can occasionally be races both longer and shorter. The upcoming Preakness Stakes at Pimlico is a thoroughbred race run over a distance of 1 3⁄16 miles on dirt.

Jump racing

Jump racing, sometimes referred to as steeplechase or hunt racing, involves horses leaping over an obstacle one or multiple times during the race. This type of horse racing is generally contested at distances of two miles or longer.

Harness racing 

This form of horse racing involves the horse pulling a two-wheeled vehicle called a bike or sulky. These rear-mounted bikes are steered by drivers. Most harness races take place on dirt tracks and are run over one mile. This is more common in North America, whereas in the UK and elsewhere they can be contested at longer distances.

Create Narrative Benefits of online horse racing betting

Those unable to attend the Preakness Stakes won’t miss a thing, aside from the fact that the Pimlico track’s infield is a giant party. Here are the advantages to leveraging online horse racing betting in your locale:

  • Convenience: Avoid the crowds and lines and browse the odds from home.
  • Security: We only recommend sites that offer top-notch security and encrypted links.
  • Paperless: Pull up the racing form from the palm of your hand.
  • Bonuses: Horse racing betting sites typically offer new customers a generous bonus. 

Popular horse racing bet types


Pick the horse that you believe will win the race. If it does, congratulations, you’ve won your bet.


Your horse needs to finish in either first or second to collect on your winning wager.


Here, you'll make a wager on a horse to finish within one of the top three positions. If the horse you've selected finishes first, second, or third, you will win the bet.


Make your prediction as to which horse will finish in first place and which one will place second. You'll win the bet if they finish in that exact order.


For the trifecta, you’ll bet on the horses that you think will finish in the top three in that specific order.

Different odds

The horse racing betting sites we highlighted earlier, along with any tied to the Preakness Stakes, will display their odds in American format. What does this mean? Let’s look at this recent example: 

Kentucky Derby winner Medina Spirit is listed at +225 and Concert Tour sits at +1,000. In this instance, a $100 bet on Media Spirit would profit $225 if he wins, and a $100 bet on Concert Tour would profit $1,000 if he were to win. 

Forget the mental math and use our betting odds converter to change American odds to decimal or fractional odds. Plus, don’t forget to check the latest Preakness Stakes odds.

Horse racing betting tips and trends

Free Picks Racing programs

Preakness Stakes racing forms are easy and free to download. These racing programs are key to your horse betting strategy, because they contain statistics on the horses and their past performances, too.

Tune-in Live betting and streaming

This fantastic feature allows you to back a horse in the middle of its race. Due to the fast-paced nature of horse racing, our recommendations for Preakness betting sites take into account high-quality functionality. Rooting for your horse in real-time with real money funds on the line is exhilarating.

Covers Global Two Color Dice Fire Bankroll

Between betting too many races, not trusting your gut, and chasing losses, your once-promising Preakness horse racing betting strategy can get blown up in a hurry. Remember those bet types highlighted earlier? Stick to the one that you are most comfortable with playing or choose the one that has provided the biggest return on your investment. Don’t pull up lame.

Covers Global Poker Chip Free bet

If you have recently signed up and registered an account with an online horse racing betting site, you will likely receive a welcome or deposit bonus. More often than not, this comes in the form of a free bet. 

Pro tip: Most horse race gambling sites require you to wager some of your own money before any winnings from the free bet can be collected.

Only the winnings from the bonus bets are returned to your account and you won’t recoup the free bet stake. Choose sports betting sites that treat these bonus bets and site credit like cash. Please read the fine print before claiming the offer.

Standings Past performances

Should Medina Spirit enter the Preakness Stakes and gallop its way to victory, they will be one win away from securing horse racing's vaunted Triple Crown. Keeping an eye on how the horse has performed in recent races can unlock the keys to your betting victory. Only 13 horses have won the Triple Crown, so stake that with a grain of salt.

Horse And Jockey Jockey experience

Prolific trainer Bob Baffert recently secured a record seventh Kentucky Derby win. Betting against Baffert’s horses has proven to be difficult, but there are no guarantees in horse racing. Securing information on a horse’s lineage and connections must be considered before you make any wager with horse racing betting sites.

Getting started at horse racing betting sites 

To bet on the Preakness or other horse races, U.S. bettors need to register with one of the horse racing betting sites highlighted earlier. Bettors in Canada and the UK can get started at an online sportsbook or bookmaker. Here’s what to expect when you are ready to wager.
