Lionel Messi is worth somewhere between $850 million and $1.1 billion depending on which valuation you trust. He's still playing professional football at Inter Miami while running a business empire that now earns him more off the pitch than on it. That gap in the estimates isn't sloppy journalism. It comes down to how you value private equity stakes in hotels, restaurants, a media company, and a slice of an MLS franchise, none of which trade on a public market with a clean price tag attached.
