At the US states where sportsbooks are legal, you can place golf bets on these platforms:
DraftKings + Caesars
With a presence in 13 different states, DraftKings is one of the biggest sportsbook operators in the nascent US online gambling industry. This is largely due to their deal with Caesars Entertainment Group from Vegas, which allows the latter access to the existing DraftKings player base.
The company originally began as a fantasy sports content provider. With the legalization of online gambling, the company has pivoted to offer sports betting along with their traditional gaming products in major leagues like the NBA, MLB, NHL, NFL, and the PGA Tour as well.
FanDuel is a direct rival to DraftKings in the arena of fantasy sports in the US. In 2016, the two companies almost had a merger which was blocked by the FTC due to regulations against monopoly formation. The two companies together account for over 90% of the fantasy sports market in the United States.
In 2018, the company was acquired by the UK betting company Paddy Power Betfair. With the repeal of PASPA, FanDuel has been active in providing sports betting facilities to their existing markets across 45 states. They are slightly behind DraftKings in this regard though, with sports betting apps now available only in New Jersey and Pennsylvania as of Q3 2019. The company has Boyd Gaming as their main casino partner.
The MGM Casino group requires no introduction to folks who are familiar with the Las Vegas Casino scene. They have over 30 resort and casino properties across the US and overseas. MGM is also actively involved in the mobile sports betting scene since 2018. They have a strategic partnership with GVC International, of the biggest global vendors of online gambling software.
Originally called PlayMGM, their online sports betting app was available in Nevada. Now they have rolled out their services in the state of New Jersey as well. The launch was marked by a new brand and many new features. The MGM sportsbook will now be called BetMGM and is currently available in these two states.
One of the oldest and most respected names in sports betting, William Hill is a British company that has been around since before WW II. The company entered the US market in 2012 and has over 100 locations in Nevada. Post-PASPA repeal, they have also rapidly expanded into the online sports betting arena.
The William Hill app is now accessible from all seven states where mobile sports betting has been legalized. They have strategic partnerships with various casinos in these states. Big leagues like the NHL has also partnered with them for mobile betting.
Formerly known as Bet Stars, this new app is the result of a partnership between Stars Group and Fox Media. The Stars Group is a Canadian company with stakes in online poker, casinos, and sportsbooks. They were previously known as Amaya Gaming. After the legalization of sports betting in the US, they acquired licenses to provide the Bet Star app in New Jersey.
Rupert Murdoch-owned Fox Media is a world-famous company that needs no introduction. Fox Bet is their first foray into the new market on online sports betting in the United States. The newly christened app is available in New Jersey and Pennsylvania, with plans pending for roll out in other states as well.
888 is yet another famous UK sports betting and casino gambling brand. Based on the British territory of Gibraltar, they are listed on the London Stock Exchange. Their foray into the US market is currently restricted to New Jersey. The app is the result of a partnership with Caesars, the casino group which owns the sportsbook license in the state.
Caesars Entertainment Group is an iconic casino and resort corporation based in Reno, Nevada. They own over 50 different casino properties and golf courses across the world. The public company has an online betting app that is currently available in the states of Nevada and New Jersey, with future releases in states like Pennsylvania.
The US online sports betting market is in a massive growth phase at the moment. With more states pushing for legalization, we can expect more and more brands and companies to enter the fray. But these apps/sportsbooks mentioned above are in prime position to capture the bulk of the market, given their early bird advantage. If you want to bet on golf, they are your best options at the moment.
