9:37am: The new ownership group also includes minority owner Robert Hale, Himmelsbach tweets.
9:20am: The Celtics are being sold to William Chisholm for a valuation of $6.1 billion, a new record for a controlling stake in a North American sports franchise, Scott Soshnick of Sportico reports (via Twitter).
Chisholm is the managing director and co-founder of Symphony Technology Group, a California-based private equity firm, Adam Himmelsbach of the Boston Globe reports. Chisholm is a Massachusetts native and lifelong Celtics fan. His involvement in the bidding was first reported last week.
The Celtics’ sale of $6.1 billion surpasses the NFL’s Washington Commanders ($6.05 billion) for the highest sum ever for a North America sports team, ESPN’s Shams Charania tweets.
Celtics co-owner Wyc Grousbeck is expected to remain governor through the ownership transition. He’ll remain in that role, continuing to oversee the team’s operations, through the 2027/28 season, Mike Vorkunov of The Athletic tweets.
The Grousbeck family expected a handful of bids for the franchise during the sales process. The Grousbeck family announced last July 1 that it was putting the team up for sale, just a few weeks after the Celtics won their 18th championship.
The Grousbeck family said then that it intended to sell 51 percent of the team in late 2024 or early 2025. The Grousbeck family is selling the team for estate and family planning considerations.
The sales price is a huge jump from the amount paid by Grousbeck 20-plus years ago. Grousbeck founded and led the group, Boston Basketball Partners L.L.C., which bought the Celtics for $360MM in 2002.
