Know About the Best Tennis Odds and How They Work


Tennis tournaments are not as extravagant as the Indian Premier League or FIFA World Cup but every year millions are exchanged, won and lost over the year through legal online sports betting. While the sport runs year long, it is the Grand Slams like Wimbledon, US Open, French Open and Australian Open that garner most of the attention of potential betters.

With Wimbledon around the corner, here is a little explainer as to betting odds in tennis work for beginners and intermediaries.

Tennis odds are a bit different from normal sporting odds. However, understanding them is not going to be rocket science for someone with a basic knowledge of the sport and little about online fantasy sports betting.


This is the most basic question for beginners. So, betting odds are — A player is listed at odds of 1.85 to win a Grand Slam match… what does it mean? It is the likelihood of that particular outcome happening. So, if a player is listed at 1.85 to win a match, these odds are what the bookmaker believes are the chances of winning the match.

The formula is: 

Implied probability = 1 / decimal odds

So, for 1.85, it will be: 1 / 1.85 = 0.5405 = 54.05 per cent.


There are two main lines when it comes to tennis betting — match odds and in-play odds. Match odds are a basic line where you predict the winner. For example, Novak Djokovic is playing an unseeded player in the first round of the Australian Open. The odds will be higher in Djokovic’s favour and he will likely be favoured to win in straight sets (3-0) with maybe losing two games (-2) per set. So, if Djokovic wins 6-2, 6-3, 6-3 — he has covered each set.

The trickiest part in understanding the basic line is the change in-play odds. For example, Rafael Nadal is playing a competitive or equal opponent like Djokovic. In this instance, Nadal may be the underdog because of Nole’s form and the Serbian is favoured to win. But if Nadal wins the first set 6-3; the odds may shift a bit in Nadal’s favour in the next set. Paying attention to the in-play odds is very important for one to adjust their bet based on momentum.

Understanding these odds will help one a lot to place bets and limit risks and increase their potential to earn a profit. Viewing the odds live with the help of a sportsbook also helps in the process of understanding and judgement. 


As mentioned above, the odds betting part of tennis changes via in-play, live-time betting options. As the odds change, a person is given the chance to place a different wager. However, you cannot remove old wagers. But, old wagers can be leveraged based on the new odds. Leverage can also be learned by placing proposition bets, which are known as prop bets. For example, there can be bets based on the number of aces served in a match, or the number of unforced errors in a single game. There are even wagers relating to players losing their cool and screaming at match officials first. 


So, here’s an example of how much you can win by placing a bet on a player.

Profit = (Stake * Odds) – Stake

So, if you have bet INR 100 on a player listed at odds of 1.85 to win a match and if the player wins, this is how much you will make.

*All values are in INR

Your Profit = (100 * 1.85) – 100

Your Profit = (185) – 100

Your Profit = INR 85
