Tennis betting is most commonly done with moneyline odds for a match. Each player is assigned a moneyline price and bettors can wager on which one they think will win.
For example, Player A is a -200 favorite to beat Player B at +170 odds. For every $1 you want to win with a bet on Player A, you must wager $2.00 and for every $1 bet on Player B, you could win $1.70. In order to win $100 with a wager on Player A, you would need to wager $200 while a $100 bet on Player B will win $170.
You can also bet on the total or Over/Under sets in a match. For example, a match may have a set total of 3.5 sets and you can bet on whether the match will have Over 3.5 sets or Under 3.5 sets. Each Over or Under bet has a set price, such as Over -160 and Under +130.
Tennis also offers futures odds for each tournament in which you can bet on which player will win that specific tournament. Every player is assigned a price according to their chances of winning. For example, Player A is a +120 favorite to win the tournament while Player B is set at +300 and Player C is at +450. These odds will adjust as the tournament progresses and players are eliminated.
There are alternative wagers in tennis, including match and player props, set handicaps, and tournament totals.
