When the U.S. Mens National Team beat Iran in Tuesdays World Cup game, advancing to the series knockout stage, it was a major win for the U.S. womens soccer team and the equal pay movement, too.

Thanks to a collective bargaining agreement both agreed to earlier this year, the teams will evenly split all the prize money awarded at various stages of their respective World Cups. Under those terms, half of the $13 million the mens team collected from beating Iran will go to the U.S. Womens National Team.

The outcome offers a stark reminder of how much less money has been on the table for female athletes. The $6.5 million the women will walk away with from the mens mid-tournament win is more than double the prize money they earned for winning the Womens World Cup championship games in 2015 and 2019 combined.

Thats because the pool of prize money offered by FIFA, which oversees the tournament, vastly differs between the two versions of the World Cup. The total prize money for the World Cup the men are playing in now is $440 million, whereas it was just $30 million for the Womens World Cup in 2019. Those totals are before each countrys soccer program takes a cut, which is 10% in the U.S.

Thats been a hard pill for players on the womens team to swallow. While theyve won four World Cup championships, making them the most successful team in international womens soccer, the men have won zero.
