The Boston Celtics are set to be sold for a record-breaking valuation of $6.1 billion USD, led by William Chisholm, managing partner of Symphony Technology Group. This sale, announced on March 20, 2025, would surpass the previous record of $6.05 billion for the NFL's Washington Commanders, established in 2023. The Celtics, who recently won their 18th NBA championship, are recognized as one of the league's premier franchises.
Chisholm, a Massachusetts native and a graduate of Dartmouth College and the Wharton School of Business, expressed his lifelong commitment to the team and the city of Boston. He emphasized the unique role the Celtics play in the local community and acknowledged the responsibility he would undertake as the new owner. Current owner Wyc Grousbeck, who purchased the team in 2002 for $360 million, has agreed to remain as CEO for the next three seasons to ensure a smooth transition.
The sale agreement involves a two-part structure, allowing Chisholm to acquire at least 51% of the franchise upon approval from the NBA's board of governors, which could occur in the upcoming summer. The remaining shares may be retained by current owners until 2028, with the possibility of selling them at a price reflecting a 20% increase based on league revenue growth, potentially valuing the team at $7.3 billion.
Chisholm's ownership group also includes Boston businessmen Rob Hale and Bruce Beal Jr. He has expressed respect for Grousbeck and enthusiasm for working with Celtics leadership, including coach Joe Mazzulla, to continue the franchise's legacy of success. This impending sale marks a significant moment in professional sports, reflecting both the financial growth of the NBA and the enduring legacy of the Boston Celtics.
