The Boston Celtics have officially been sold for a record-breaking $6.1 billion to a group led by Massachusetts native and private equity executive Bill Chisholm. This sale marks the highest price ever paid for a sports team in North America, surpassing previous records in the industry. As the team transitions to new ownership, questions arise about maintaining the championship core and the financial implications of such a major sale. Former owners see a remarkable return on their investment, generating nearly 1,700% profit from the transaction. Amid this shift, the NBA community expresses curiosity about how this sale may influence discussions around potential expansion teams like the Seattle Sonics.
