Lionel Messi is a billionaire. The kid whose first professional contract was reportedly scrawled on a napkin — with a clause covering his growth hormone treatment because his local Argentine club couldn't afford it — has crossed the ten-figure mark thanks to a combination of Inter Miami, Apple, Adidas, and the commercial machinery of American sport.
He joins Cristiano Ronaldo in that rarefied air. Two players, one generation, both now worth over $1 billion. Whatever you think about the GOAT debate, the financial scoreline is level.
How the US changed everything
Moving to MLS was widely framed as a retirement lap. A warm send-off in pink. What it actually became was a commercial rebirth. The Apple TV deal that came bundled with his Inter Miami move didn't just pay Messi — it gave him equity-style upside tied to MLS subscription growth. That's not an athlete's salary. That's an investor's play.
Barcelona found Messi as a teenager at Newell's Old Boys, a club that couldn't fund the growth hormone treatment a young Messi needed. The Spanish giants covered it. The napkin deal — informal, unconventional, arguably the most consequential piece of paper in football history — launched a career that would eventually outgrow every club, every league, and now every salary structure the sport had previously imagined.
What this means beyond the headline
For MLS, Messi's billionaire status is a validation of the league's commercial ambition. His presence has already shifted how seriously American soccer is taken globally. Sponsorship rates, broadcast deals, jersey sales — all moved when he signed. His odds of remaining in MLS beyond his current contract just got shorter, too, because Inter Miami can now credibly argue they're part of something bigger than a farewell tour.
Ronaldo got there first, largely through his Al Nassr deal and years of meticulous brand-building. Messi took a different route — later to the commercial game, but the US market accelerated everything.
From a napkin in Rosario to ten figures. The growth hormone clause ended up being quite the investment.
