The Best Tennis Betting Sites For 2025
Is it Legal to Bet on Tennis in America?
Gamblers in America can bet on tennis matches at local sportsbooks or offshore sports betting sites. Domestic sports betting has spread to nearly every state in the USA, but there are a few holdout regions where it's yet to become legal. Alternatively, offshore sportsbook sites can legally accept players nationwide, even in states where local books are illegal.
The reason that sportsbook sites located in other countries can accept American bettors is that they do not fall under the authority of state or federal gambling laws. However, it is still essential to ensure that any site you do business with is legitimate, so we've gathered the best-reviewed offshore sportsbooks here in this guide.

The Legal Status of Betting on Tennis In The United States
In 2018, the Supreme Court of the United States repealed PASPA, essentially giving each state the right to permit local sportsbooks. Since then, nearly every US state has opted to legalize sports betting, with options for in-person, online, or mobile wagering or a combination of the three. Sports betting bills have circulated the legislatures in most states where sportsbooks are not yet legal, with only Utah appearing to be completely uninterested.
Another option for legally betting on sports in the United States is using an online sportsbook located in another country. These are referred to as offshore sportsbooks, and they can skirt US gambling laws due to their international location. The SCOTUS ruled in 2023 that online gambling occurs where the servers are located, so any bets placed with an offshore sportsbook are technically taking place in that country where the book is located (ie, not the USA).
Tennis Betting Explained
Tennis Match Lines
Each tennis match on the tour will feature a corresponding betting line (also called a match line) where you can place wagers on different aspects of play. Here is an example of a match line for us to refer to going forward.
Nuno Borges vs. Ugo Humbert Match Line
- Game Spread: Borges +2.5 (-110), Humbert -2.5 (-120)
- Moneyline Odds: Borges +165, Hubert -200
- Over: 23.0 (-120)
- Under: 23.0 (-110)
The game spread allows you to bet on how many games a player will win by. Hunbert is favored to win by at least 2.5 games, so he'll need to win by at least three games to cover the spread for bettors who wagered on him. Borges is the underdog and is expected to lose by at least 2.5 games. He'll need to lose by two or fewer games to cover the spread. Spread betting is a way for oddsmakers to create an even match-up for gambling.
Placing a wager on a player's moneyline odds is a simple wager on whether they will win the match. If they win, your payout will be calculated based on how much you risked, weighed against the moneyline odds. Borges is the underdog at +165, so sportsbooks will pay you more than what you wagered. A $1 bet on Borgos will net you $1.65 in profit if he wins the match.
Tennis Futures
Futures odds in tennis involve wagering on the winning player from a list of all remaining contenders that have yet to be eliminated. Each player will have moneyline odds that reflect their chances of winning, and let you know how much you can win against the bet that you make on them. Here is an example to work from.
2025 Women's Wimbledon Futures
- Aryna Sabalenka +275
- Elena Rybakina +500
- Coco Gauff +700
- Iga Swiatek +700
- Mirra Andreeva +1000
- Madison Keys +2000
- Jasmine Paolini +2500
- Qinwen Zheng +2800
- Barbora Krejcikova +3300
- Emma Navarro +3300
- Jessica Pegula +3300
- Ons Jabeur +3300
- Emma Raducanu +4000
- Karolina Muchova +4000
- Naomi Osaka +4000
- Danielle Collins +5000
Using these Wimbledon futures, we can establish that Aryna Sabalenka is the favorite to win. Even though she is the top odds-getter, the odds are still positive and will reward gamblers with exponential profits if she wins. A $1 bet on Sabalenka will net $2.75 if she wins Wimbledon. Tennis futures are posted before the tournament begins and remain online until the semifinals.
Tennis Prop Bets
Proposition bets allow gamblers to wager on aspects of matches and tournaments that don't involve betting lines and futures. These wagers can involve statistical over/unders, set betting, wagering on exact scores, total tie-breaks, first service scoring, and any other stat that oddsmakers find important enough to create odds for. Here is an example of a tennis prop.
Set Betting Marton Fucsovics vs. Taylor Fritz
- Taylor Fritz Wins 2-0 +125
- Taylor Fritz Wins 2-1 +260
- Marton Fucsovics Wins 2-0 +360
- Marton Fucsovics Wins 2-1 +460
This prop allows you to gamble on the exact set score at the end of the match. Once again, each outcome features moneyline odds, with the potential outcomes listed from most to least likely to occur.
Betting Live Tennis Odds
Sportsbooks used to stop taking bets on tennis matches a few minutes before the opening serve. Now, in-match betting is available at most tennis gambling sites, taking action on all sorts of match-related odds. Most of the focus of live betting is placed on match lines, with odds lasting into the final set in most cases.
Tennis prop bets and tournament futures will also remain live, but they are often removed randomly during the match or tourney. The important takeaway is that with the inclusion of live betting on tennis matches, the gambling can occur at any time you choose.
Understanding Legal Online Tennis Betting Options in the USA
Both domestic and international sports betting sites are available in the USA and are a legal option for players of appropriate age to use. Locally regulated sportsbooks are limited to use within the states where they exist and cannot be accessed outside of their borders.
The same is not true of offshore sportsbook sites, as they can extend service to all 50 US states. However, some sportsbooks that are located overseas have chosen not to serve certain markets like Nevada due to an overabundance of local options already present.
We prefer offshore gambling sites for their access across the country and their massive selection of tennis odds. Our gambling experts have reviewed the websites featured here and are the brands that we use when betting on tennis online ourselves.
