Boston Celtics Sold for Record $6.1 Billion to William Chisholm's Group

The historic two-stage transaction marks the highest valuation for a North American sports franchise, pending NBA approval.

William Chisholm, managing partner of Symphony Technology Group, leads the investor group purchasing the Boston Celtics for $6.1 billion.
The sale includes a two-stage structure, with 51% of the team sold now and the remaining shares set for 2028.
Wyc Grousbeck will remain as governor and CEO of the Celtics through the 2027-28 season to ensure operational continuity during the transition.
The $6.1 billion valuation surpasses the previous record of $6.05 billion for the Washington Commanders, setting a new benchmark for U.S. sports franchises.
The Celtics' new ownership faces financial challenges, including a projected $500 million payroll for next season, the highest in NBA history.
