Citadel founder Ken Griffin played a pivotal financial role in the appointment of U.S. men's national soccer team head coach Mauricio Pochettino, underscoring the billionaire hedge fund manager's long-standing commitment to developing the sport in the United States, according to a report by Reuters.

A Citadel spokesperson confirmed that Griffin made the largest philanthropic contribution towards securing Pochettino's appointment in 2024, following the U.S. team's disappointing Copa America campaign. The former Tottenham Hotspur, Paris Saint-Germain and Chelsea manager has since guided the national team into the knockout stages of the 2026 FIFA World Cup.

The contribution reflects Griffin's broader investment in U.S. soccer. Through previous donations, he has funded the construction of community mini-pitches in Chicago and Miami, while he and Miami developer Stephen Ross recently donated more than 1,200 World Cup tickets to local residents.

Beyond sport, Griffin has built Citadel into one of the world's largest and most successful hedge fund firms, overseeing approximately $68 billion in assets. His support for U.S. Soccer highlights a growing trend of alternative investment executives deploying philanthropic capital to strengthen elite sporting institutions and expand grassroots participation.
