What she doesn't have yet is a product that is her sport. Every dollar of her value still flows through somebody else's infrastructure.
The market has shifted from endorsement to ownership
In 2025 the global athlete endorsement market hit $62.4 billion, and is forecast to nearly double to $118.7 billion by 2034. The sports influencer segment alone is projected to grow from $1.2 billion in 2024 to $4.7 billion in 2033 at a 16% CAGR. Step back further. The broader creator economy sits at $202 billion in 2025 and is on track to exceed $848 billion by 2032.
What's changed isn't the existence of endorsement income. It's who owns the upside. For the last three decades, an athlete was a celebrity rentable by the hour — a Gatorade spot here, a Nike commercial there, a headshot on a Wheaties box. In 2025, the top tier of athletes is increasingly choosing equity stakes over cash deals. Kevin Durant's stake in the sleep tracker Whoop is up 81× since his 2017 investment. LeBron James's SpringHill Company sold a minority position in 2024 to a syndicate of RedBird Capital, Nike, Epic Games and Fenway Sports Group at a $725 million valuation. These are no longer endorsement checks. They're cap table entries.
Campaigns featuring athletes generate up to 7× the return on ad spend of campaigns that don't, with brands earning an average of $5.78 in media value for every $1 invested. That asymmetry is what now finances the ownership pivot.
The new stack: athlete = creator + investor + platform owner
Consider what the top tier of basketball alone has built away from the court:
| Athlete | Vehicle | Scope | Status |
|---|---|---|---|
| LeBron James | SpringHill Company | Film, TV, marketing, athlete stories | $725M valuation |
| Kevin Durant | Thirty-Five Ventures / Boardroom | 100+ startup stakes, media brand | Coinbase, Whoop, Dapper Labs |
| Russell Westbrook | RW Digital / Honor the Gift | Apparel, digital media | Active portfolio |
| Serena Williams | Serena Ventures | VC fund, $111M raised | 85+ portfolio companies |
| Tom Brady | TB12 / Autograph | Performance brand + NFT platform | Active |
| Dude Perfect | Dude Perfect Media | YouTube native, 60M+ subs | Media empire |
What the list shares: these are no longer passive celebrity endorsements. Each is a P&L the athlete operates, staffs, and in most cases started themselves in the middle of their playing career. The old template was "play, retire, open a restaurant." The new template is "play, build a holding company in parallel, IPO or recapitalize on exit."
Non-sports brands now drive the athlete economy spend
The composition of brand dollars flowing to athletes has shifted materially. Non-sports brands accounted for 44% of all athlete endorsement spend in 2025, up from 37% in 2022. Luxury, fintech, gaming, telecom, health — the categories paying top athletes now are categories whose customers don't watch games for a living. They're paying for the athlete's audience, not their sport.
That's not bad news for sport. It's a leading indicator. It tells you the athlete has become a standalone media asset whose value is only loosely correlated with league-governed play. Livvy Dunne is the clearest case: the top ranked college athlete NIL valuation at $4.1 million, of which a negligible share flows from her gymnastics career. Ilona Maher was the single most engaged athlete at the 2024 Paris Olympics despite rugby sevens being a sport that most of her audience had never watched.
The athlete is no longer where the sport happens. The athlete is where the sport's attention happens. The sport is only one of the products the athlete sells.
LSC Research — April 2026 perspectiveThere's still one layer missing: a product that is the sport
Here is the oddity inside the $62 billion endorsement economy. The athlete has built a production company. The athlete has built a venture fund. The athlete has signed with a luxury-goods brand and a fintech app and a sneaker deal that's now partially equity. The one thing the athlete has not built, because no one has built the infrastructure to allow them to build it, is a commercial product whose core is their sport itself.
The gap shows up clearly in the numbers. Caitlin Clark's 2024 base WNBA rookie salary was approximately $76,000. Her annualized 2024-25 endorsement income is estimated at more than $11 million. The ratio is 144:1 endorsement-to-salary. Every dollar of Clark's revenue touches her basketball career as a referent, but almost no dollar of her revenue comes from basketball. The sport is the signal. It is not the product.
FSP's thesis: give the athlete a product that is their sport
The athlete already has (1) an audience, (2) a production stack to reach that audience, and (3) an investment vehicle to own any upside. What they don't have is a participation platform that lets fans do what they've been watching the athlete do, at scale, under the athlete's own brand, with a recurring revenue share back to the athlete.
Consider a concrete worked example. Ilona Maher has roughly 4.5 million Instagram followers and a sport (rugby sevens) that no major U.S. sportsbook lists. A branded FSP skill challenge (a passing accuracy bracket, a tackle ladder, a conditioning test structured as a bracket) priced at $75 entry with a 1% conversion of her audience generates $3.4 million gross for a single event. Split standard 45% to the athlete, that's $1.5 million in one event from a sport that currently has no direct revenue mechanism for her. She doesn't need a new brand deal. She needs a new product.
This is the third revenue line for the modern athlete. Endorsement pays for attention. Equity pays for ownership. Participation pays for the sport itself. FSP is the layer that makes the third line possible.
Why this matters for the next decade
The idea that athletes are content is now table stakes. Every major sports business is already writing it into their strategy. What comes next is product ownership. The athlete no longer just appears in a brand's campaign or takes equity in someone else's company. They operate a commercial product built on their sport, and they own the entire stack.
This is where the convergence actually lands. When an athlete can simultaneously be the performer, the content producer, the platform owner, and the party sharing revenue on fan participation, that is the complete stack. The current system gives them three out of four. FSP's thesis is that the fourth piece, a participation product built for sport, is worth more than the other three combined, because it is the one that uses the sport as the product rather than as the backdrop.
The athletes who win the next decade won't be the ones with the biggest brand deals. They'll be the ones who turn their sport into a product their fans can buy.
