Boston Celtics Sold for Record $6.1 Billion to William Chisholm

The historic sale, pending NBA approval, will see Wyc Grousbeck remain as CEO through 2027-28 to ensure a smooth transition.

The $6.1 billion sale marks the highest valuation ever for a North American sports franchise, surpassing the $6.05 billion paid for the Washington Commanders in 2023.
William Chisholm, a Massachusetts native and lifelong Celtics fan, will lead the new ownership group alongside private equity firm Sixth Street and other investors.
The Grousbeck family, who have owned the Celtics since 2002, cited estate planning as the reason for the two-stage sale, with the remaining shares to be sold in 2028.
The sale agreement does not include TD Garden, but the Celtics' lease at the arena extends through the 2035-36 season, ensuring operational stability.
The Celtics face financial challenges under the new ownership, with a projected $500 million payroll next season due to luxury tax penalties under the NBA's new collective bargaining agreement.
