Tennis players are amongst the wealthiest sports people on the planet - a win at this year’s French Open will earn you a hefty €2.55 million.
It’s also one of the few sports to offer similar fiscal rewards to both male and female players - with all the major titles now offering equal money (although Wimbledon didn’t until 2007, decades after the US Open in 1973).
Add in money-spinning advertising and sponsorship deals, personal appearances and shrewd investments, and these aces can become fabulously wealthy.
Lucrative television rights mean that the prize money in the sport has never been higher, meaning that youngsters like Carlos Alcaraz and Jannik Sinner are seeing their bank balances challenge those of the all-time greats - with plenty of years left to play.
Here are the 20 richest tennis stars in the world in 2026, according to CelebrityNetWorth.
