Boston Celtics Sold for Record-Breaking $6.1 Billion, Marking Largest Team Sale in North American History

American sports history was made Thursday when the Grousbeck family sold the Boston Celtics to California private equity executive Bill Chisholm. The team was sold for the first time in two decades at a $6.1 billion valuation, marking the largest sale price for a North American sports team in history.

Lifelong Celtics fan Chisholm has assembled a strong group for this purchase, including current Celtics owner Rob Hale, Bruce A. Beal Jr. (president of Related Companies), and Sixth Street, a global investment firm.

“I understand how important the Celtics are to the city of Boston – the role the team plays in the community is different than any other city in the country,” Chisholm said in a statement. “I also understand that there is a responsibility as a leader of the organization to the people of Boston, and I am up for this challenge.”

This sale comes at a pivotal time for the Boston Celtics, who are competing for their second championship in this era. With over $400 million allocated to their roster, and as the NBA luxury tax and salary cap continue to fluctuate, major decisions will need to be made. This record-breaking sale further sets the market for the escalating cost of owning a North American sports franchise.

The NBA is a league experiencing significant global growth, and the valuation of a team with both national and international appeal expands opportunities for merchandise, events, and activations, allowing franchises to create lucrative long-term revenue streams.
