The Boston Celtics have reset the market on pro sports team valuations.
Earlier Thursday, it was announced that the storied basketball team was sold for a record $6.1 billion to Bill Chisholm, managing partner and co-founder of Symphony Technology Group. This deal sets a new benchmark for North American sports franchise transactions, surpassing the $6.05 billion sale of the NFL’s Washington Commanders in 2023.
Notably, the deal does not include TD Garden, the Celtics’ home arena, which remains under the ownership of the NHL’s Boston Bruins. However, the Celtics’ lease at the arena extends through the 2035–36 season, offering stability for the franchise’s operations.
The Grousbeck family, which purchased the Celtics for $360 million in 2002, will retain governance over the team until the 2027–28 season. Wyc Grousbeck, the current team governor, is set to oversee the transition and ensure continuity in the leadership of the team.
Chisholm’s Symphony Technology Group is a private equity firm based in Menlo Park, Calif. This acquisition further underscores the growing influence of private equity in sports, as the firm moves to establish its presence in one of the most iconic franchises in the NBA.
This monumental transaction has implications not only for the Celtics but also for the broader sports industry, as it sets a precedent for the potential valuation of future NBA expansion teams, such as those in Las Vegas and Seattle.
With Boston’s payroll expected to hit a record $500 million next season, the sale underscores the high financial stakes involved in professional sports. The Celtics’ new ownership will have significant implications for both the team’s operations and the evolving landscape of the sports business as a whole.
