A group led by Bill Chisholm, managing partner at Symphony Technology Group, has reached an agreement to purchase the Boston Celtics for a record-breaking valuation of $6.1 billion, sources told ESPN. This deal sets a new high for a North American sports franchise, surpassing the $6.05 billion paid for the NFL’s Washington Commanders in 2023. It also eclipses the previous NBA record set when Mat Ishbia bought the Phoenix Suns for $4 billion in 2022.
The new ownership group includes Boston business leaders Rob Hale, a current Celtics shareholder, and Bruce Beal Jr. The deal was announced on Thursday, though specific terms were not disclosed.
Chisholm, a lifelong Celtics fan, described the acquisition as a dream come true. “This process started when I attended a game at the old Boston Garden for my seventh birthday. I’ve been a rabid fan ever since,” he said. “Wyc has done an incredible job running this franchise, and I’m committed to building on that success.”
The sale follows the Celtics’ historic 18th NBA championship last June, when they defeated the Dallas Mavericks in five games. Shortly afterward, the controlling ownership group — Boston Basketball Partners, LLC — announced plans to sell the franchise after more than two decades of stable leadership. Wyc Grousbeck and Steve Pagliuca have led the group since acquiring the team in 2002 for $360 million.
Grousbeck will remain CEO and governor for the next three seasons at Chisholm’s request. “We wanted to find the right person with the resources and commitment to win banners — Bill checks every box,” Grousbeck said.
The transaction involves a two-part sale, with Chisholm initially acquiring at least 51% upon NBA board approval, expected by summer. Remaining shares can be sold by 2028 at a premium tied to league revenue growth.
Chisholm emphasized his focus on winning: “My approach is to win and raise banners. Aligning with Brad Stevens and the current leadership is key to sustaining success.”
The Celtics are on track to exceed $500 million in combined payroll and luxury tax next season, raising financial challenges under the new collective bargaining agreement. However, with a strong roster and stable leadership, the team remains a top contender for another title.
“This is the best sports franchise in the world,” Chisholm said. “I bleed green — and I’m up for the challenge.”
