Prominent St. Louis businessman and philanthropist Dr. Richard A. Chaifetz has acquired an ownership interest in the San Francisco Giants, becoming a partner in the storied franchise’s ownership group.
The announcement came Thursday from the Chaifetz Group, the private investment firm chaired by Chaifetz. “I am proud to become part of the ownership group of the San Francisco Giants,” Chaifetz said in a statement released by his firm.
Chaifetz, born in August 1953 in Brooklyn, New York, is a self-made billionaire with a diverse background in business, psychology, and philanthropy. He founded ComPsych Corporation in Chicago in 1984, growing it into the world’s largest provider of employee assistance programs (EAPs) and behavioral health services, serving over 160 million individuals in more than 200 countries.
A licensed neuropsychologist with a Psy.D., Chaifetz has built his fortune through ComPsych and the Chaifetz Group, a venture capital and private equity firm focused on early- and mid-stage growth companies, real estate, and sports investments. His net worth was estimated between $1.4 billion and $2.8 billion as recently as 2024.
Chaifetz’s ties to St. Louis run deep. A magna cum laude graduate of Saint Louis University (SLU) with a bachelor’s in psychology, he has donated tens of millions to his alma mater. His gifts include naming rights to Chaifetz Arena (after a $12 million donation) and the Richard A. Chaifetz School of Business (following an additional $15 million in 2018). He has also supported institutions like the Field Museum of Natural History and Miami University’s Farmer School of Business.
In sports, Chaifetz has prior investments, including ownership of the St. Louis Shock in Major League Pickleball. His entry into MLB marks a major step into one of the premier professional sports leagues.
The San Francisco Giants are owned by a large partnership group, led by Chairman Greg Johnson (son of principal shareholder Charles B. Johnson). The group includes dozens of investors, with recent additions like retired legend Buster Posey (who joined in 2022) and institutional investors such as private equity firm Sixth Street (which acquired a minority stake in 2025 to fund ballpark upgrades and the Mission Rock development).
Chaifetz’s investment aligns with the Giants’ strategy of bringing in high-profile partners to support the franchise’s long-term growth. The team, valued at around $4 billion by Forbes in recent estimates, boasts eight World Series titles and a passionate fan base at Oracle Park.
While details of Chaifetz’s stake size were not disclosed, his addition brings fresh capital and expertise from outside the Bay Area, potentially aiding initiatives in player development, facilities, and community engagement.
