The Most Expensive Sports Contracts In History

With the ink still drying on his US$503 million deal, Patrick Mahome II now holds the most expensive sporting contract in history. Naturally, the news of the Kansas City quarterback’s twelve-year agreement stoked our curiosity about what other most expensive sports contracts were out there.

Before we proceed, a few details need to be addressed…

  • Numbers are not indicative of endorsement deals or any other supplementary forms of income which often contribute to total career earnings (e.g. Roger Federer’s 2019 winnings amounted to US$6.3 million vs. 2019 endorsements which amounted to over US$100 million).

  • Athletes of individual sports may have been excluded due to the fact that prize money, promotional deals, and so forth are not always guaranteed within a contract (e.g. Floyd Mayweather’s six-fight pact with Showtime guaranteed approximately US$200 million; a pay-per-view side deal earned him an additional US$250 million – also note the use of “pact” and not “contract”).

  • Numbers are based purely on what is public knowledge, therefore undisclosed salary contracts/backdoor deals associated with some high-profile athletes have also been excluded (e.g. Cristiano Ronaldo’s four-year contract with Juventus is reported to be worth at least US$340 million, which includes a transfer fee and an estimated annual salary of US$64 million – but his contract has never been explicitly cited or confirmed).

Now… where were we?



From the top 100 selection of most expensive sports contracts, a staggering 55 entrants came from Major League Baseball, 29 from the NBA, and 12 from the NFL. The rest are from a mix of boxing, Formula 1, and soccer. Clearly, the US of A is where it’s at.

Interestingly enough, the majority of these contracts were active in the last decade/valid until well into the next. And by the latter I mean 2025 and beyond, approaching 2030 and even 2031. Which raises the question – given the current upward trend, how long before a billion-dollar contract comes along?
