In a landmark transaction, Bill Chisholm, co-founder and managing partner of Symphony Technology Group, has agreed to purchase the Boston Celtics from the Grousbeck family for a record-breaking $6.1 billion.
This sale sets a new high for North American sports franchises, surpassing the $6.05 billion paid for the NFL’s Washington Commanders in 2023.
Chisholm, a Massachusetts native and lifelong Celtics fan, co-founded Symphony Technology Group in 2002. Under his leadership, the firm has managed assets exceeding $10 billion, focusing on investments in software, data, and analytics companies.
The Grousbeck family, led by Wyc Grousbeck, acquired the Celtics in 2002 for $360 million. Under their stewardship, the team secured its 17th NBA championship in 2008 and its 18th title last season, solidifying its status as one of the league’s most successful franchises.
As part of the agreement, Grousbeck will continue in his roles as CEO and Governor through the 2027-2028 NBA season, ensuring a smooth transition of ownership.
The sale is pending approval from the NBA’s Board of Governors, a process expected to conclude by this summer.
