Online Horse Race Betting

Online horse race betting is the oldest form of legal online gambling in the US. Off-track betting (OTB) parlors, the original form of mobile horse race betting, originated in Nevada. Now, bettors across the US have access to horse betting without having to leave home to visit a race track or an OTB.

The best online horse racing sites offer a range of bonus offers, including deposit-match promotions for new members. And while some states restrict the practice, over 30 plus Washington D.C. allow online horse race betting.

The first OTB parlors outside Nevada began to appear in New York in 1970. OTB facilities offer bettors the opportunity to place bets into pari-mutuel betting pools across state lines, on races around the country and abroad. The Interstate Horseracing Act of 1978 then officially legalized OTB parlors in the US, and an amendment to the act in 2000 put language in place legalizing internet-based mobile horse race betting as well.

Several mobile apps offer legal online horse racing bets in the modern era. BetMGM, TVG, and TwinSpires lead the pack as the biggest brands in mobile horse race betting.

BetMGM Horse Racing

BetMGM is partnering with NYRA (New York Racing Association) to power its new horse race betting platform. BetMGM Horse Racing will be available in California, New York, Ohio, and more. 

While the welcome bonus isn’t for sure, it will likely be a 100% deposit match up to $200 or more. Anything less would be surprising.

That’s because BetMGM Sportsbook & Casino consistently offers some of the best promotions in online betting. Available in many states across the US, the all-in-one gambling platform even boasts multiplayer poker. No matter what you want to bet on, BetMGM has you covered as long as it’s legal in your state. Soon, that will include horse racing as well.

TVG Horse Racing

TVG operates as both a 24-hour television network dedicated to horse racing and a mobile horse race betting site. TVG stands for “Television Games Network.” It began operations in 1999.

The TVG Horse Racing website and mobile app gives bettors access to a pair of 24-hour television channels dedicated to horse race handicapping. TVG also allows bettors to wager on races at more than 100 domestic and international racetracks.

TVG operates legally in 33 states, including California, New York, New Jersey, Pennsylvania, and Kentucky.

Originally an outlet founded by the owners of TV Guide magazine, the British sports betting company Betfair purchased TVG Horse Racing in 2008. TVG operates in the US under the banner of the FanDuel Group, a US subsidiary of Flutter Entertainment (formerly known as Paddy Power Betfair).

Bettors can download TVG as a mobile app for iOS and Android devices or enjoy the platform’s betting and television services from a desktop browser.

Claim Offer: New players at TVG can receive a 50% deposit match up to $250 total.


TwinSpires began accepting horse race bets in 2007, and it was acquired by Churchill Downs Incorporated in 2010. Churchill Downs purchased BetAmerica seven years later, and the company is currently in the process of rebranding all BetAmerica platforms to TwinSpires. That’s likely why BetAmerica is no longer offering any welcome bonuses on its site.

Today, TwinSpires Horse Racing is available in over 30 states, including California, Pennsylvania, and New York. Meanwhile, TwinSpires Sportsbook is available in several states with legal sports betting, and TwinSpires Casino is available in Michigan, New Jersey, and Pennsylvania. That makes TwinSpires one of the most prominent online betting brands in the US.

TwinSpires can be downloaded as a mobile app for both iOS and Android devices, or accessed from a desktop browser. New bettors can take advantage of a 100% deposit match up to $200. Terms and conditions apply.

TwinSpires offers bets on all domestic races as well as many overseas tracks located in the UK, New Zealand, and beyond. The official betting partner of the Kentucky Derby, TwinSpires is named after the twin spires seen at the Churchill Downs racetrack. So you can expect some very enticing bonus offers leading up to the Derby.

What Types Of Bets Are Available On Online Horse Betting Sites In The US?

Pari-Mutuel Betting

Pari-mutuel betting puts all of the money wagered by bettors on a race into a single payout pool. The money from the pool is then divided among winners, minus the vigorish, or “juice,” taken by the venue that offers the bet.

This kind of wagering pits bettors against each other, compared to traditional fixed-odds bets where bettor wager against the house. Pari-mutuel betting is by far the most common wagering style in horse racing.

Single Horse Bets

Single horse bets involve wagering on one particular horse to finish in a certain place in a race.

These wagers allow for bets on whether a horse will finish first (win), first or second (place), or anywhere in the top three (show). Odds on a single horse bet are always higher for “win” bets.

Multiple Horse Bets

Multiple horse bets attempt to predict where two or more horses finish in a given race.

Bets in this category include:

  • Quinella – Two horses must finish first and second, in any order, for the bet to win.
  • Exacta – Two horses must finish first and second, in that order.
  • Trifecta – A trifecta bet wins if the bettor predicts the top three finishing horses and the exact order in which they finish.
  • Superfecta – A superfecta bet wins if the bettor predicts the top four finishing horses and the exact order in which they finish.

Multiple Race Bets

For a multiple race bet to win, a chosen horse must win two or more consecutive races. These bets include Daily Double (two wins in a row), Pick 3 (three consecutive wins), and so on.

What Types Of Bonuses Are Available When Betting On Horse Races Online?

Risk-Free Bet

Risk-free bet bonuses offer a rebate on the first bet made at a mobile horse race betting platform. This kind of bonus is also commonly offered at online casinos and sportsbooks.

Risk-free bets guarantee a refund on an individual wager, but only if that bet results in a loss.

At TVG, for example, new players can take advantage of a $200 risk-free bet offer. Using this offer, new bettors place their first wager at TVG and are eligible for up to a $200 rebate in the event of a loss.

The refund amount matches the total of the original wager, up to a $200 cap. A $100 bet, for example, would result in a $100 refund in the case of a loss. A $500 bet would be eligible for the maximum refund amount of $200.

At TVG, the first bet must be made within 15 days of the first deposit to be eligible for the risk-free bet offer.

Deposit Match Bonus

Deposit match offers award bonus money that matches a certain percentage of the first deposit on a mobile wagering platform. This kind of bonus is widely offered across multiple online gambling sites.

For example, BetMGM Horse Racing will offer a 100% bonus up to $200 in partnership with NYRA Bets. The same welcome bonus is offered by TwinSpires Horse Racing as well. 

However, both platforms have their own sets of terms and conditions, such as TwinSpires crediting your bonus in 50% increments as you bet 4x the deposit amount. So be sure to read the T&Cs before taking advantage.

Is Online Horse Race Betting Legal In The US?

Off-track betting (OTB) parlors, the predecessor to modern online horse betting, were legalized in 1978. The Interstate Horseracing Act of 1978 contained language to explicitly legalize interstate wagering on horse racing.

A 2000 amendment to the Act legalized internet-based horse race betting. Though many forms of online gambling have faced legal hurdles in the US, online horse race betting is currently legal in more than 30 states.

What Is The History Of Horse Race Betting In The US?

Horse racing in the US traces its roots to the early 1800s. The tradition of horse racing in England carried over into American settlements.

Some of the earliest vestiges of modern-day horse race betting in the US still stand today. Saratoga Race Course opened in 1863, and the upstate New York venue is still one of the most hallowed horse racing venues in the US.

All three races making up the American Triple Crown debuted by 1875. Betting on horse racing has long been synonymous with the sport itself in the US. By 1900 more than 300 horse racing facilities were open for betting around the country.

Pari-Mutuel And Off Track Betting

Pari-mutuel betting was introduced in the US in the early 1900s and is still the most common method of horse race betting used today.

A total of 32 US states currently offer legal pari-mutuel betting. OTB parlors sprang up in New York in the 1970s, which allowed bettors to engage in a form of online pari-mutuel betting.

The Interstate Horseracing Act of 1978 legalized OTB facilities, and in 2000 an amendment was added to the act expressly legalizing the use of the internet for off-track betting.

The UIGEA And Online Horse Race Betting

The Unlawful Internet Gaming Enforcement Act (UIGEA) of 2006 effectively outlawed all internet-based gambling transactions that crossed state lines.

The UIGEA, however expressly allows an exemption for online horse race betting. The federal government permits individual states to enforce their own legislation on online horse race betting.

Nearly 40 states allow mobile horse race betting in some form. Horse race wagers are the only form of online gambling transactions allowed to cross state lines in the US.

Is It Safe To Bet On A Legal Online Horse Betting Site?

Legal, regulated online horse race betting platforms in the US include brands like BetMGM, TVG, and TwinSpires. Several other legitimate, legal mobile horse race betting apps operate in the US as well.

Bettors should use caution and research mobile betting apps thoroughly to determine if they’re legally operating sites. Government agencies regulate all legal platforms. This ensures a secure experience for the bettor as well as accountability for the operating betting service.

Betting apps like TwinSpires and TVG are owned by Churchill Downs Incorporated and the FanDuel Group, respectively. These multi-billion dollar companies operate with a vested interest in providing prompt payouts, safe betting, and security of personal information.

Offshore betting platforms do not operate under the same level of regulation as legal betting sites. Betting at an offshore site does not offer the security of wagering on a legal platform. Offshore sites operate in the US illegally, and as such betting on these sites is also illegal.

What Options Are There To Deposit And Withdraw At Online Horse Betting Site?


One of the fastest ways to get funds on an online horse racing site is through ACH/eCheck deposit. This method draws directly from a bank account as an electronic check, and the funds usually become available instantly.

The ACH/eCheck deposit method is known as BetCash, Telecheck, and ECash at various horse race betting sites. Some sites occasionally reject the ACH/eCheck method but is still the most widely accepted deposit method at legal online gambling sites.

Debit/Credit Cards

Most online horse race betting sites allow deposits using a Visa or Mastercard debit/credit cards. These deposits can sometimes be rejected by the issuing bank, but when it does work the funds are instantly available on the betting account.

Some betting sites charge fees for using debit/credit cards for deposits. Credit card deposits are also subject to cash advance fees from the issuing bank.


PayPal deposits provide one of the most reliable ways to put money on a mobile horse racing balance. The PayPal process takes a few extra steps compared to some other methods.

PayPal deposits have a nearly 100% success rate, and the funds become instantly available on a betting account.

PayNearMe and Green Dot MoneyPak

PayNearMe allows players to deposit at participating 7-Eleven locations. GreenDot Moneypak offers a similar service at participating Walgreens, Rite Aid, and Safeway Kroeger locations.

Both of these methods come with fees, and bettors should only use these deposit methods as a last resort.
