Horse Racing Betting by States

Pennsylvania horse racing betting is available both online and in-person for bettors aged 18 or older. There are six race tracks in the state, and the industry is overseen by the Pennsylvania State Horse Racing Commission. We recommend playing on TVG in The Keystone State, but other options exist as well.

Tennessee horse racing betting is available online-only as there are no racetracks in the state. Like Pennsylvania, we also recommend TVG for bettors within the state. Unlike many other states in the country, Tennesee’s legal framework for horse racing betting is not fully fleshed out or made completely clear, but it is still available for bettors aged 18 or older.

New Jersey horse racing betting is a solid industry, allowing bettors aged 18 or older to place bets both online and in-person at one of the state’s three racetracks. Bettors can utilize 4NJBets for advance-deposit wagering or MonmouthBets for fixed-odds horse racing betting. 4NJBets is powered by TVG, a trusted provider of horse racing betting.

New York horse racing betting is available both online and in-person at their nine racetracks. These racetracks include the iconic Belmont Park, located on Long Island. We recommend Empire State players utilize TVG for the best horse racing betting experience, although there are other options available in the state as well.

Texas horse racing betting is only available in-person at one of the states racetracks. There is currently no online horse racing betting permitted in the state, but bettors can also wager on simulcast races held elsewhere when they visit the racetracks in the state.

California horse racing betting is the only form of online gambling currently permitted in the state. Horse racing betting is legal both online and in-person at the state’s four racetracks. As with most other legal horse racing betting states, we recommend TVG for bettors to have the best experience.

Colorado horse racing betting is legal online and in-person for bettors aged 18 or older. Colorado is the only other state other than New Jersey to offer fixed-odds betting on horse races, giving bettors in the state a great option for their wagers. Despite Colorado only having one in-person racetrack, options are plentiful for those looking to get into horse racing betting.

What Types Of Bets Are Available On Online Horse Racing 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 is in contrast to how, for example, New York sportsbooks pay out, which is based on the odds of the wager and the size of the bet, not how many others placed the bet as well.

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?

Second Chance Bet

Second-chance 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 real money casinos and sportsbooks.

Second-chance bets guarantee a refund in bonus money on an individual wager, but only if that bet results in a loss.

The refund amount matches the total of the original wager, up to a certain cap. For example, let’s say the cap at an operator is $200. A $100 bet that loses would result in a $100 bonus refund. A $500 bet would be eligible for the maximum refund amount of $200 in bonus money.

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.

However, platforms have their own sets of terms and conditions. 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 outside of Nevada to engage in a form of online pari-mutuel betting for the first time.

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 Racing 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.

Online Horse Race Betting FAQ

Probably not. There are some legal question marks on this one.  Generally, states that allow horse betting say in their laws that as long as the race is simulcast (i.e. televised or otherwise shown on a screen) within the state, you can bet on it. However, there are some questions if eventually federal law will strike that down.

All betting apps use geolocation technology to see the state you are physically located in.  Whatever restrictions exist in the state where you are present will be reflected in your betting options on the app.

Horse race betting in the US is offered through pari-mutuel betting pools. Pari-mutuel betting puts all wagers on a race into a single pool, with payouts divided among all winning tickets.

The payout on a particular horse can go up or down based on how bets are divided across all participating horses in a race.

Mobile platforms like TVG operate as both horse race betting sites and streaming video services. In many cases, bettors wager on a race and then watch the race on the same platform in which they made the bet.
