#1. Tiger Woods: $700 million Net Worth
With an estimated net worth of $700 million, Tiger Woods is still the most valuable sports athlete on the planet. Some highlights of his career include winning 14 professional major tournaments and 71 PGA Tour events. Tiger turned pro in 1996 and since then, he has accumulated a massive $92.8 million from 239 career PGA starts. However, he has earned a lot more from his endorsement deals with the likes of Gatorade, American Express, Asahi, Accenture, Rolex and Gillette etc. Unfortunately, his earnings have dipped in the recent years with many sponsors shunning him largely owing to his infidelity scandals.
