12:37pm: The Celtics confirmed in a press release that the majority ownership group plans to sell of its shares in the team (Twitter link via Chris Forsberg of NBC Sports Boston).
“The controlling family of the ownership group, after considerable thought and internal discussion, has decided to sell the team for estate and family planning considerations. The managing board of the ownership group expects to sell a majority interest in 2024 or early 2025, with the balance closing in 2028, and expects Wyc Grousbeck to remain as the Governor of the team until the second closing in 2028.”
12:13pm: On the heels of their record-setting 18th NBA championship, the Celtics will be hitting the market, according to ESPN’s Adrian Wojnarowski of ESPN (Twitter link). Sources tell Wojnarowski that the team’s majority ownership group, led by Wyc Grousbeck, intends to make the franchise available for sale.
Grousbeck has been the team’s Governor since his Boston Basketball Partners group purchased the Celtics for $360MM back in 2002. Boston has won two NBA titles under his stewardship, in 2008 and just a few weeks ago.
A source tells Adam Himmelsbach of The Boston Globe that while Grousbeck is selling his stake in the Celtics, other minority shareholders are expected to remain invested in the team (Twitter link).
As ESPN’s Bobby Marks tweets, the Celtics could be the most expensive team in NBA history in 2025/26, when a potential super-max extension for Jayson Tatum kicks in. Grousbeck will be looking to sell his stake just as severe roster-building restrictions are implemented in the new CBA.
As of December, Sportico had the Celtics ranked as the fourth-most valuable franchise in the NBA, with a valuation of $5.12 billion. That figure seems likely to have risen in the past eight months, given the team’s on-court success.
Grousbeck, 63, is a Massachusetts native who has built his wealth through various investments over the past few decades. His father, Irving, is a billionaire who co-founded Continental Cablevision.
