The Boston Celtics’ ownership group has agreed to sell the team to Bill Chisholm, the co-founder and managing director of the Symphony Technology Group (STG), for a record $6.1 billion, according to a source who spoke to The Boston Globe. The deal surpasses the record recently set by the Harris Group, which acquired the Washington Commanders for $6.05 billion in June 2023.
Chisholm helped co-found STG in 2002, where he currently serves as the organization’s chief investment officer and managing partner. Even though STG is located in California, Chisholm grew up in Georgetown, Massachusetts, and has been described as a longstanding Celtics fan who possesses “encyclopedic knowledge” of the team, according to a person close to him who spoke to The Boston Globe.
“Growing up on the North Shore and attending college in New England, I have been a die-hard Celtics fan my entire life,” Chisholm said in a statement obtained by CBS News. “I understand how important the Celtics are to the city of Boston – the role the team plays in the community is different than any other city in the country. I also understand that there is a responsibility as a leader of the organization to the people of Boston, and I am up for this challenge.”
Wyc Grousbeck says in a statement that new Boston Celtics owner William Chisholm has “asked me to run the team as CEO and Governor for the first three years, and stay on as his partner, and I am glad to do so.”

According to industry sources, the ownership group includes Chisholm, current Celtics co-owner Robert Hale, Related Companies president Bruce Beal Jr., and the global investment firm Sixth Street.
Current Celtics co-owner Wyc Grousbeck will remain the team’s governor and oversee franchise operations through the end of the 2027-28 season.
“I trust [Grousbeck] and those guys in their decision. And understanding the culture that we’ve set and we have, and sustaining that and trying to make it better,” said Celtics star forward Jayson Tatum in a statement made earlier this week. “We’ve got some great people in this organization and on this team, and we’ve worked really hard to build something special. I trust that they’ll make the right decisions in whoever that next group is.”
The sale still needs to be approved by the NBA’s Board of Governors before it can be finalized.
