Tennis also thrived during medieval times when King Henry VIII was passionate about the game and played often using crude equipment.

Tennis Betting Odds
One betting line that we see on nearly every professional tennis tournament features winner odds like the ones featured below. These lines place moneyline odds next to each tennis player’s name that imply their chances of winning the entire tournament.
There are also traditional match game lines that feature spreads for the amount of total games the victor will win by, the total over/under for games played, and straight winner odds in money line form. To top it all off, there are a fleet of tennis prop bets that can cover any occurrence during the television broadcast. These will be further detailed in a section below titled “Tennis Bet Types.”
Grand Slam Tennis Tournaments
Each calendar year there are four grand slam tournaments that attract the top men and women’s professional tennis players from around the world. How many major championships a player has won determines their legacy, so each grand slam tournament features the best players bringing their A game, and also inspires legions of fans to place bets on the matches.
Most Men’s Grand Slam Titles: Roger Federer 20 (Raphael Nadal is active with 19)
Most Women’s Grand Slam Titles: Margaret Smith Court 24 (*Serena Williams is active with 23)
Legal Betting On Wimbledon
Wimbledon is the most prestigious grand slam tournament on the pro tennis schedule each year and takes place over two weeks, or a fortnight, in jolly ol’ England. It is the only grand slam event that features a grass court which gets worn down over the 14 days of play. Betting on Wimbledon features the most action out of any of the grand slam tournaments each year.
The grass court significantly slows down the speed that the tennis ball travels, creating for games that last for more strokes on average. This gives an advantage to slower tennis players that can serve the ball at high speeds. There is also the added pressure of playing in front of the Queen of England if your match is featured enough to be played at Centre Court.

Most Wimbledon Titles – Men’s: Roger Federer 8, Women’s: Martina Navratilova 9

Legal Betting On The US Open Tennis Tournament
Women and men’s US Open tennis betting odds can be found on the boards at sportsbooks nearly all year round, with oddsmakers pausing only briefly following each tournament to gather up a line for the following year’s event.
The tournament has been around since 1891 and is once of two grand slam tennis competitions that are played on hard courts. Hard court tennis matches feature faster ball travel as well as quicker movements from the competitors due to the solid grip the surface provides. US Open play features less volleys and quicker games, especially on the men’s side.
2020 Winners: Men’s: Dominic Thiem, Women’s: Naomi Osaka
Most US Open Tennis Titles – Men’s: Roger Federer, Pete Sampras, Jimmy Connors tied with 5 each, Women’s: Chris Evert and Serena Williams both have 5
2021 US Open: August 30-September 12
Legal Betting On The French Open
The French Open is the only grand slam tournament that features clay as the playing surface. The red clay causes players to slide when they try to stop in place, so they have to get accustomed to the extra motion when preparing to strike a ball while on the go.
All that sliding around causes the lines on the court to blur, and is easily the most entertaining tennis surface to watch a match commence upon. Rafael Nadal is still active as a player and is without a doubt the greatest clay court player of all time, earning 12 French Open titles during his career.
If you are going to bet on the French Open, don’t bet against Nadal. In fact, odds have yet to be produced for the 2020 men’s French Open winner because he hasn’t said if he intends to play.
2020 Winners: Men’s: Rafael Nadal, Women’s: Ashleigh Barty
Most French Open Tennis Titles – Men’s: Rafael Nadal 12, Women’s: Chris Evert 7
2020 French Open: September 21-October 11
Legal Australian Open Betting
Each year, pro tennis players from around the globe head down under to compete in the Australian Open and earn a shot at a grand slam title for their shelf. The tourney is played on hard courts, just like the US Open, and features high-speed ball movement and players moving rapidly to and fro.
The Aussie Open has been in play since 1905 and sports the highest attendance numbers out of all the grand slam events, hosting over 800,000 fans over the course of the tournament. Betting on the Australian Open is also popular, with Novak Djokovic often featured near the top of the money line odds.
2020 Winners: Men’s: Novak Djokovic, Women’s: Sofia Kenin
Most Australian Open Tennis Titles – Men’s: Novak Djokovic 8, Women’s: Serena Williams 7
2021 Australian Open: February 7-February 21
Tennis Bet Types: How Do Tennis Odds Work?
Match Lines - Individual match lines like the one below include three betting options - the spread, straight winner odds, and totals.
Novak Djokovic vs. Filip Krajinovic
- Spread: Djokovic -5.0
- Winner: Djokovic -500, Krajinovic +375
- Total: 21.0
How To Bet On Tennis Spreads - The above betting line implies that Djokovic will win by a total of 5 or more games based on the spread of -5.0.
A wager can be made on either side of the spread. Djokovic will need to win by 6 games or more games for bets on him to pay off. Alternatively, spread wagers will not pay out if made on Krajinovic unless he can lose by less than 4 games, or if he can outright win.
Winner – For bettors that want to keep it simple and do an old-fashioned bet on the winner of the tennis match, money line odds are the way to go. Since competitors are rarely equal, odds are placed next to each player’s name that indicates their chances of winning, as well as the payout that can be collected if they do.
Because Djokovic is favored to win, a bet of $500 on his -500 money line odds is required to earn a payout of $100. On the other side of the equation, a $100 bet on Krajinovic, who is a +375 underdog, will earn a cash sum of $375 if he can upset Djokovic.
Totals - The over/under indicates that the match will last for 21.0 games. Oddsmakers declare the total number of games that they predict the match will last and bettors are then able to wager on which side of the line they think the total will fall on. These are also fairly simple bets that don’t require a lot of research.
Futures - Futures odds are tennis betting lines for events that have yet to occur, like the ones featured above in sections for each of the winners of the four major tournaments. Another example is “How many grand slam tournament titles will Serena Williams earn before she retires?”
Set Lines – These are just like the match line above, but all of the odds are placed on a single set.
What Happens To A Tennis Bet If A Player Retires From A Match? – If a player retires before the completion of the first set, all bets are voided and refunded. If a player retires after the conclusion of the first set, then the bet stands.
