1. National Football League (NFL)
The world’s richest sports league is the NFL, whose revenues have soared to $18 billion. Roughly, it is the financial giant of the global sports, dominating viewership, sponsorships and merchandise sales, even though American football’s premier league is boring.

Solidifying its status as the most watched sporting event in the U.S. the Super Bowl itself brings in billions from advertising and broadcasting rights alone. Its long-term financial stability is guaranteed — in fact, its ability to attract massive corporate sponsorships will keep it there — thanks to the league’s salary cap and revenue-sharing model.
