Basics of tennis betting

Betting on tennis isn’t all that different from betting on other sports. Here’s a look at the basic ways you can bet on tennis:

Tennis tournaments seed players, then match up the top seeds with the lowest seeds and unseeded qualifiers in the first round. The winners advance through a single elimination bracket until a champion is crowned.

Each match presents a number of betting opportunities. You can pick match winners and lay down bets at basic money line odds, get a little more advanced with match spreads and totals, or simply pick who you think will win the entire tournament.

Money line: Money line bets allow you to simply pick a player to win a particular match. You book the bet at odds posted at the time. Oddsmakers will post a favorite with negative odds representing how much you’ll need to bet to win $100 plus your bet back.

For example, Serena Williams might be a -150 favorite, meaning you’ll need to bet $150 to win $100, plus your $150 bet back. Oddsmakers will also post an underdog with positive odds representing how much each $100 you bet will earn.

For example, Coco Gauff might be a +150 underdog, meaning a $100 bet will get you $150 , plus your $100 bet back if Gauff wins.

Game spread: Game spread adds a different wrinkle to money line betting. Oddsmakers post a margin of games that the favorite is expected to win by, and this number must be factored into the final score by game to determine a betting winner. You pick who you think will win with the game spread factored in and book the bet at adjusted money line odds.

Set spread: Set spread bets ask you to pick whether the favorite can win two sets to none in a three-set match or the underdog can take a set. In five-set matches, set spread bets ask you to pick whether the favorite can win by three sets to none or the underdog can take a set.

Over/under: In most sports, the over/under, or total, refers to a line on how many total points will be scored in a game. In tennis, the over/under line is on the total number of games in a completed match. You bet on whether there will be more or fewer games than the line set by oddsmakers.

Tennis live betting

Live betting on tennis matches is the process of betting on a match once it has already begun. Colorado online sportsbooks will allow you to bet on the basic markets listed above during a match at odds that are adjusted throughout. The markets move quickly, and the odds can change in an instant.

Plus, live matches present a number of betting opportunities for the points, games and sets within. Here’s a list of some of the other live betting markets open for tennis matches:

  • Points: A bet on who will win the next point in a match.
  • Games: Money line bets on which player will win the next game.
  • Sets: Money line bets on which player will win the next set.

Tennis futures

Just like the name suggests, futures are bets on a future outcome. In tennis, most futures markets revolve around Grand Slam events and various player accomplishments. These include:

  • Australian Open winner
  • French Open winner
  • US Open winner
  • Player of the year

You can bet on both men’s and women’s winners in each category at professionally set odds that are adjusted throughout the year. There are also futures markets for most ATP and WTA tour stops.

Tennis prop betting

Prop betting markets revolve around the game within the game. In tennis, that means certain aspects of the match but not necessarily the match itself. Straight bets on a tennis match involve who wins and loses and by how much. Tennis props revolve around any other question in a match you might ask.

Colorado online and mobile sportsbooks may offer tennis props that include:

  • Whether there will be a tiebreak in a match.
  • Will it be a straight sets victory by either player?
  • Over/under a certain amount of games for each player.

Betting on tennis Grand Slams

Various tennis tournaments are held throughout the year. However, the four Grand Slam events present the biggest and best tennis betting opportunities.

These two-week tournaments are the biggest and best each year. There’s worldwide TV coverage and widespread international media interest. In fact, interest in the sports itself is as high as it gets during Grand Slams, which means more active tennis betting markets than any other time of the year. That includes more live betting, props and odds boosts.

Here’s a list of the four Grand Slam events on the calendar and everything you need to know about betting on the Grand Slams in Colorado:

  • BNP Paribas Open ATP Tour Masters 1000. Indian Wells, California. March. (Hard)

Betting on men’s vs. women’s tennis

The biggest difference between men’s and women’s tennis is the length of the matches in Grand Slams. Men play the best of five sets in Grand Slams, while women’s matches are the best of three sets.

Men play either the best of three or five sets in ATP events. WTA matches are all best of three sets.

The style of play is also different. Men’s tennis is generally the more powerful game with an emphasis on serving. Women’s tennis is a bit more of a finesse game with longer rallies.

Of course, there are powerful women and finesse players on the men’s side, as well.

All of this should be taken into consideration when betting on men’s and women’s tennis matches. A little research focused on these areas will go a long way in helping you pick tennis winners.

Betting on the Davis Cup

The Davis Cup is an international championship series with teams representing their home nations in singles and doubles competition.  The format has been changed for 2021 with the Davis Cup World Group I and World Group II now playing for spots in the final. Plus, traditional Davis Cup Nations Rankings are no longer used to determine which group a nation is in.

Davis Cup qualifying from around the world leads to the Davis Cup Finals. You should be able to bet on Davis Cup qualifying involving the US team and the entire 2021 Davis Cup Finals at Colorado sportsbooks.

That means bets on a team to win outright, individual players and teams to win matches and futures on teams to win the Davis Cup Finals.

Bet on Olympic tennis

Tennis is an Olympic sport, and various men’s and women’s tennis tournaments will be held as a part of the Olympic Games. The next Olympics will feature the following tennis tournaments:

  • Men’s singles
  • Men’s doubles
  • Women’s singles
  • Women’s doubles
  • Mixed doubles

With an Olympic gold medal on the line, Olympic tennis is considered a fifth Grand Slam event. The top players in the world compete, and anyone who can win all five in a single year is considered to have won a Golden Slam. Steffi Graf is the only player to have accomplished this.

Olympic tennis brings with it another opportunity to bet on something akin to a Grand Slam event. That means individual match betting, live betting and futures as well.

Tennis betting rules

The rules of tennis are fairly straightforward. Therefore, the rules when it comes to betting on the sport are relatively simple and easy to understand.

However, the game has its quirks, and certain very specific betting rules may apply to certain situations. You should always check out the tennis betting rules specific to the Colorado sportsbook of your choice before betting.

In the meantime, here are some relatively common situations and the betting rules you should get a grasp of before making a tennis wager:


Players sometimes retire during a match due to injury or other circumstances. Check with the sportsbook where you bet to see if and when matches are considered complete after a player retires. Sportsbooks vary in considering a match complete if either:

  • The first ball is played.
  • One set has been played.
  • Two sets have been played.
  • The full match is completed.

Otherwise, all bets on the match are returned.


If a player’s opponent withdraws from the tournament prior to the match, it is considered a walkover. All bets on the match are returned.


Weather is a factor in outdoor tennis tournaments. It can cause a match to be postponed before it starts and delay a match at any time. As long as the match is completed within a reasonable timeframe, most bets are considered live until the match is done.

Tennis Betting FAQ

You can bet on a games spread where a line on the number of games a player wins by must be factored into the final games score. Or you can bet on a set spread where a line on the number of sets a player wins by must be factored into the final sets score.

Finding the best lines on any tennis match isn’t all that difficult. In fact, you can do it from home, sitting on your couch. Just browse through the tennis markets at various Colorado sports betting apps, and look for the best prices on a bet.

It’s called line shopping; it’s easy to do, and it will save you money in the long run.

Match fixing is a problem in tennis, even in Grand Slam events. However, the Tennis Integrity Unit was set up in 2008 and is working toward ridding the game of corruption.

Over the past three years, three players have been banned from the sport for match-fixing. None were upper-echelon players.

Stick to reasonably sized bets on high profile matches featuring the world’s top players to avoid match-fixing issues.

Each game is won by the first player to win four points by two points clear. Points are called 15 (1), 30 (2), 40 (3), and Game (4). 40-40 is referred to as deuce. Since a player must win by two points, the player who wins the point at deuce is said to have the advantage. If the player with the advantage wins the next point, that player wins the game. Otherwise, it’s back to deuce.

Sets are won by the first player to win six games by a margin of two games. A tiebreaker can also decide a set that is tied at six games each. Tiebreakers are won by the first player to win seven points by two points, or 10 points by two points for match tiebreakers.

Matches are either a best-of-three format, where the first to two sets wins, or a best-of-five format, where the first to three sets wins.
