In a landmark move, the NBA has unanimously approved the sale of the Boston Celtics to an investment consortium led by private equity executive Bill Chisholm, valuing the illustrious franchise at a staggering $6.1 billion—setting a new record for U.S. professional sports team transactions.
Chisholm, co-founder of STG Partners and lifelong Celt, will initially acquire a 51% controlling interest, with a contractual option to gain full ownership by 2028 at a higher price point—potentially bringing the total value to $7.3 billion.
Meanwhile, outgoing owner Wyc Grousbeck will remain CEO and shift into the role of alternate governor during the transition.
This sale eclipses the previous record held by the NFL’s Washington Commanders, purchased for $6.05 billion in 2023, and becomes the second-highest franchise sale in NBA history—surpassed only by the Los Angeles Lakers’ recent $10 billion valuation.
Serving as both a testament to the franchise’s competitive legacy—including 18 championships—and a reflection of soaring valuations in sports business, the deal signals a new era for the Celtics under Chisholm’s stewardship.
