To break it down at the most basic level, female athletes have historically earned a small fraction of their male counterparts because of television revenue. The secret to understanding pro athlete salaries is that it has little to do with how many people attend the stadium and more to do with how much television networks are willing to pay for broadcasting rights.
For example, 67% of the NFL's revenue comes from their lucrative TV deals versus 17% for ticket sales. That split is 49-31 for the MLB and 54-26 for the NBA. The dilemma for women's sports is that the broadcasting revenue has never been there, which limits the profitability of each league. For example, while the NBA just signed a record-breaking 11-year $76 billion TV deal, the WNBA had a deal that paid out $60 million yearly, far from enough to cover $290 million in estimated expenses, resulting in a let loss that capped how much players were getting paid. It is why the average NBA salary is $11 million with a maximum of $63 million, while the average WNBA salary is $147 thousand and a maximum of $240 thousand.
Then, the Caitlin Clark phenomenon happened, a once-in-a-lifetime athlete who will indirectly generate over a billion dollars and impact generations of female athletes.
Starting with her time in Iowa, her games commanded millions of viewers, not only shattering women's college records but pro basketball in general. Her win over LSU in the 2024 Elite Eight commanded 16.1 million viewers, the most for a college basketball game ever and the second most ESPN has had for a basketball event since 2012. It had more viewers than every MLB and NHL game from the 2023 season.
That somehow fell short of the 24.1 million viewers for her national championship loss to South Carolina, the most-watched sporting event since 2019, excluding the Olympics, World Cup, and NFL.
