Here are the factors we consider when ranking and recommending the best US Open betting sites: Licensing: We only recommend golf betting sites that are licensed by the UK Gambling Commission (UKGC). UKGC-licensed operators ensure that customers’ details are protected and that sites are regulated. Welcome offer: Value is imperative for all betting sites, especially when betting on the US Open. It starts with the welcome offer that should at least match the rest of the industry for rewarding new customers. Promotions: We only recommend betting sites that offer a complete collection of the best promos for new and existing customers. Using any of our top 20 betting sites for golf, users can expect to find free bets, moneyback specials, price boosts, super boosts, extra places and much more. Value: We strive to find operators that provide optimum value on your US Open betting odds. You’ll struggle to find regulated bookmakers that provide better value than our recommended betting sites, but customers should always shop around to ensure you find the best price before placing a bet online. Markets: The US Open is one of the most prestigious golf events of the year and as such, there should be ample betting markets to reflect the importance of the major. There should be extensive options for bettors based on players, groupings, nationality, props and specials. Usability: Betting sites are not effective unless they have sound usability and functionality for all features. Our recommended operators tick all the boxes when it comes to usability, providing a sound online betting experience. App: The best US Open betting sites should offer a quality online betting app for both Apple and Android devices. Operators should provide ease of use for navigating, placing bets, cash outs and more when using betting apps. Payment options: These betting sites should offer a wide range of payment methods to reflect modern day transactions. Debit card and bank transfers should be a staple, but methods should also include options for PayPal betting, Apple Pay betting, Google Pay betting and pre-paid cards. Below, we’ve given punters some detail on the most common markets to use for betting on the US Open for golf. Outright Winner Market: This is simply bet on who will win the tournament. Each-Way Betting: This is essentially making two bets – one on your chosen player to win, and one on them place. Betting sites offer extra places for each-way bets. Look out for the best extended US Open offers before placing your bet as well as the each-way odds price that are usually a 1/5 of the outright price. Top 5/10/15/20 Finish: This is a straightforward wager on players to finish in the top positions. The odds lessen in value with the more places you add, although your chances of winning are increased. Bear that in mind before wagering. Regional Betting: Betting on the Top American, Top European, Rest of the World, player groupings and similar. Match Betting: This is betting on head-to-head player matchups. Bookmakers either select two players or allow you to select your own based on the pool of players in the tournament. Make The Cut: A simple wager on whether the player will make the score for the cutdown after the second round of action. You can also bet for a player to miss the cut. Prop Bets & Special Markets: These markets are more specific, and include first-round leader, a player to get a hole-in-one, the winning margin and many others.

If you’re having a bet on the US Open, it’s vital to practice responsible gambling. Betting can be addictive and it’s important to stay in control of your gambling. Never treat gambling as a way to make money, never bet more than you can afford and when the fun stops, stop. Gambling sites offer punters tools, like deposit limits, profit and loss trackers and self-exclusion options, to help them stay in control. You’ll find the same tools on casino sites, slots sites and poker sites too, so long as they’re regulated by the UKGC. Never bet with unregulated bookmakers. But if you ever feel like you need help or advice on gambling addiction, don’t hesitate to contact one of the charities or organisations below.
