Michael Jordan’s first NBA contract paid him $6.3 million across seven seasons. The shoe deal he signed the same summer, with a Nike that was then a distant runner in the basketball market, has since paid him well over $1 billion. Same 21-year-old, same July, two documents with wildly different futures.
That gap explains almost everything about the athletes who became billionaires. Salaries make players rich. Ownership, royalties and equity make them wealthy enough to stop counting. Only a few dozen people in the history of professional sport have crossed the ten-figure line, and the routes they took are more instructive than the numbers themselves.
The short list is shorter than you think
Forbes tracks a handful of billionaires whose fame came from a pitch, a court or a ring. Michael Jordan sits near the top with a fortune estimated above $3 billion. LeBron James reached the mark in 2022 while still averaging 30 points a game. Tiger Woods crossed $1 billion in career earnings back in 2009, the first athlete ever to do it. Cristiano Ronaldo and Floyd Mayweather have both cleared the line, and Romania’s Ion Tiriac has quietly built a fortune near $2 billion. Lionel Messi and Magic Johnson hover around it depending on whose valuation you read.
Compare that with the tens of thousands of professionals who have played top-level sport in the past fifty years, and the odds look brutal. The richest athletes of all time share a habit that has nothing to do with talent: they treated their name as an asset to be owned rather than a service to be sold.
Michael Jordan: the royalty cheque that never stopped
Nike’s offer in 1984 was $500,000 a year for five years, plus a royalty on every pair sold. Nike projected $3 million in Air Jordan revenue for the first three years combined. It sold $126 million in the first twelve months alone.
The rest is arithmetic. Jordan Brand now generates roughly $6.6 billion a year in revenue, and Jordan’s royalty sits somewhere near 5% of it. He has earned more from that single clause than from every contract, appearance fee and endorsement of his playing career combined.
The Charlotte Hornets were the second act. He bought a minority stake in 2006, took majority control in 2010 for a reported $275 million, and sold the bulk of it in 2023 at a $3 billion valuation, keeping a slice on the way out. A mediocre basketball team turned out to be an excellent piece of real estate.
LeBron James: building an empire mid-career
Most athletes build after they retire. James started at 25. His 2015 lifetime deal with Nike was reportedly worth more than $1 billion, and he took equity in brands like Blaze Pizza and Lobos 1707 tequila instead of flat endorsement fees. In 2021 he became a partner in Fenway Sports Group, which handed him a stake in Liverpool FC.
SpringHill, the production company he co-founded, sold a minority stake to RedBird Capital at a valuation near $725 million. When Forbes put his net worth at $1 billion in 2022, he was the first active NBA player to get there, which says as much about timing as it does about money. The billion-dollar fortunes built by the wealthiest athletes almost always include one asset held for twenty years, not twenty investments flipped in two.
Cristiano Ronaldo: the first footballer to bank a billion in wages
Ronaldo got to $1 billion in career earnings in 2020, the first team-sport athlete to do it, and that was before the Al Nassr contract that reportedly pays him around €200 million a year. Wages alone got him most of the way, which is unusual.
What came after is the more interesting part. CR7 is a brand with hotels in Lisbon and Madrid, a fragrance line, a fitness chain, a museum and a licensing business that runs on his face. His Instagram following, north of 600 million, is worth more than most of his sponsorships. You can see where that kind of reach ranks among the most followed celebrities in 2025, and why sponsors pay a premium for it.
Tiger Woods and Floyd Mayweather: two opposite roads
Woods made his billion through endorsements. At his peak, Nike, Titleist, General Motors and Accenture paid him more to do nothing on a Tuesday than most PGA Tour pros earned in a season. The 2009 scandal cost him sponsors, but the comeback and the 2019 Masters restored the machine. He now has his own Nike successor brand, Sun Day Red.
Mayweather took the other route entirely. Almost no blue-chip sponsors, no corporate partners, just pay-per-view revenue funnelled through his own promotion company. He earned roughly $1 billion in purses across his career and kept far more of it than a fighter signed to a rival promoter would have.
The quiet billionaire nobody mentions
Ion Tiriac played ice hockey for Romania, then tennis, reaching a French Open final in doubles. His sporting career was solid but unremarkable. His business career made him one of the wealthiest people in Eastern Europe.
He moved into banking after the fall of communism, built an insurance and leasing empire, opened car dealerships and held the licence for the Madrid Masters tennis tournament for years. His estimated $2 billion fortune owes very little to prize money and everything to knowing which doors were opening in 1990 and walking through them early.
What the billionaires have in common
Read enough of these stories and the same mechanics keep repeating.
- Equity over fees. Jordan took royalties, James took shares, Mayweather took the promoter’s cut. Cash is taxable and finite; ownership compounds.
- One enormous bet, held for decades. Almost every fortune traces back to a single deal signed young and never sold.
- Control of the name. The athletes who licensed their likeness cheaply rarely made the list.
- Timing. Nike in 1984 was a gamble. Air Jordan was not a sure thing.
- A business brain in the room. An agent, a college friend, an older brother. Someone had to read the contract properly.
Most won’t make it, and the reason isn’t spending
The often-quoted figure is that 60% of NBA players go broke within five years of retirement. The stat comes from a 2009 Sports Illustrated piece and has been contested since, but the direction of it holds. A $100 million career is not a $100 million fortune. Taxes take a third, agents and managers take a slice, and a divorce can take half.
The bigger leak is investment. Retired athletes are surrounded by people offering restaurants, car washes and nightclubs, deals that need a working owner in a city they no longer live in. Jordan’s team was mediocre. His Nike royalty still paid.
The next wave is already forming
Mathieu Flamini, an Arsenal midfielder most fans remember as a squad player, co-founded a biochemical company called GF Biochemicals that has been valued in the billions. Conor McGregor’s sale of his Proper No. Twelve whiskey stake reportedly netted him a nine-figure sum, more than any purse he ever earned. Serena Williams runs Serena Ventures, which has backed more than sixty startups.
College athletes now sign NIL deals at eighteen with agencies that teach equity structures. Saudi money has inflated football wages to the point where a young forward in Riyadh can bank a billion before thirty. Women’s sport is attracting capital it has never seen.
The next group of athlete billionaires will probably look different from Jordan: younger, more global, more likely to own a piece of a league or a media company than a sneaker royalty. The maths will be the same, though. Somebody has to sign the paper that pays them for twenty years instead of twenty games.
