Record Deal: Bill Chisholm becomes the new owner of the Boston Celtics
The businessman acquired the most decorated franchise in the NBA in exchange for the highest amount in the history of American sports
The NBA closed one of the most important chapters in its financial history with the official announcement of the sale of the Boston Celtics, completed this Tuesday. The buyer was William "Bill" Chisholm, a 56-year-old magnate who paid more than 6.1 billion dollars to acquire at least 51% of the institution.
The transaction, which received unanimous approval from the league's Board of Governors, becomes the most expensive transaction for a professional sports team in the United States. Chisholm is expected to acquire full control in 2028, when the franchise's value could exceed 7.3 billion.
The new principal owner introduced himself as a lifelong supporter of the Boston team: "We're committed to maintaining the Celtics' proud history and raising expectations so the team can once again reach the next level of championships," he stated in a press release.
The new management structure includes Wyc Grousbeck, who will become co-owner and CEO, and Aditya Mittal as alternate governor. Other prominent names such as Bruce Beal, Rob Hale, Mario Ho, and Ian Loring are also joining, as well as the international fund Sixth Street as a significant shareholder.

This transfer closes a cycle that began in 2002, when Grousbeck and his group purchased the franchise for 360 million dollars. During those two decades, Boston won two NBA titles (2008 and 2024), reached two additional finals, and participated in 20 out of 23 postseasons.
Chisholm's arrival coincides with a challenging outlook: next season the team won't be able to count on Jayson Tatum, who is seriously injured, which will test the new management both in sports and institutionally.

The sale of the Celtics adds to a wave of multi-billion-dollar transactions in the NBA. Meanwhile, Mark Walter has agreed to acquire the majority of the Los Angeles Lakers in a deal estimated at 10 billion dollars, although nothing is official yet, while Tom Dundoncompleted the purchase of the Portland Trail Blazers for more than 4 billion.
