Top 10 Richest Athletes of All Time

Cristiano Ronaldo ranks fourth with a $600 million net worth, fueled by a $200 million annual salary at Al Nassr—the highest in sports history. His Instagram account, with over 600 million followers, generates $3 million per sponsored post. The CR7 brand spans hotels, gyms, and fashion, while career football earnings exceed $1.3 billion. With 900+ career goals and five Ballon d'Or awards, Ronaldo has won titles in England, Spain, and Italy. He is the most-followed person on social media globally.

Lionel Messi's net worth of $650 million is built on a career total of $1.3 billion in earnings, yet his post-soccer earnings may dwarf that figure. His 2023 Inter Miami deal grants a reduced $12 million annual MLS salary but includes equity in the club and a share of Apple TV's MLS Season Pass revenue.

Roger Federer's $550 million net worth is driven by shrewd post-retirement deals: his equity in On Running, which IPO'd in 2021 at a $6 billion valuation, is worth an estimated $300 million — more than 2x his total $130 million in prize money. His 20 Grand Slam titles and elegant brand yield a marketing value that outearns Lionel Messi's Adidas deal on a per-year basis ($100M vs. $67M). Federer proves that sophistication and longevity in branding can outperform any controversial headlines.

The Mayweather vs. Pacquiao fight generated $600 million, and the McGregor bout added $550 million. Even in exhibitions, he nets $10–50 million per event, often for just a few rounds. Mayweather's self-promotion remains a masterclass in monetizing controversy.

Magic Johnson's $1.2 billion net worth dwarfs his $40 million NBA salary — over 30% of which was earned after retirement. Through Magic Johnson Enterprises, he sold Starbucks franchises for $200 million, owns EquiTrust life insurance with $3.6 billion in assets, and co-owns the Los Angeles Dodgers (turning a $130 million investment into a $5 billion valuation), LAFC, and the Los Angeles Sparks. His 12-theater chain in underserved communities proved profitable, generating $50 million annually.

The Irishman earned an estimated $100 million from the 2017 Floyd Mayweather boxing match alone, plus tens of millions more in UFC earnings over his career. Yet his true fortune came from Proper No. Twelve Irish Whiskey: in 2021, he sold his majority stake to Proximo Spirits in a deal reportedly worth up to $600 million, pocketing an estimated $150 million himself — a sum that rivals his combined fight purses from boxing and MMA. With a 22-6 MMA record and 0-1 in boxing, McGregor has been the UFC's biggest PPV draw for over a decade, proving that personality and promotion can generate as much value as the fights themselves.

She earned $94 million in career prize money — the most in women's tennis history — but Serena Ventures has invested in 78+ companies including MasterClass, Tonal, and Impossible Foods, with a combined portfolio valuation exceeding $14 billion. She also owns stakes in the Miami Dolphins and Inter Miami CF, adding sports equity rarely seen among female athletes. Her S by Serena fashion line and lifetime Nike deal generate ongoing revenue streams. Retired in 2022 with 23 Grand Slam singles titles, she remains one short of Margaret Court's record — a gap that fuels her relentless ambition.
