In a blockbuster move that’s shaking the sports world, the NBA has officially approved the record-setting $6.1 billion sale of the Boston Celtics to an investor group led by billionaire Bill Chisholm. The price tag is the highest ever paid for a North American professional sports franchise, underscoring the Celtics’ iconic legacy and massive market power.

Chisholm outlasted at least two other bidders to secure majority ownership of the storied franchise. Once the deal closes, he’ll take control of at least 51% of the team, with plans to assume full ownership by 2028—a step that could boost the franchise’s valuation to an eye-popping $7.3 billion.

The deal ends an era for Wyc Grousbeck, who spearheaded the Celtics’ $360 million purchase in 2002. Grousbeck, who presided over championships in 2008 and 2024 and four Finals appearances, will reportedly step aside as governor but remain CEO and alternate governor.

Under Boston Basketball Partners LLC, the Celtics added to their unrivaled tradition of greatness. With 18 championships— third most among all North American pro sports franchises behind only the Yankees and Canadians’—the green-and-white dynasty now enters a new chapter.

For Celtics fans, it’s a historic moment: the team that delivered Bill Russell, Larry Bird, Paul Pierce, and Jayson Tatum is now part of the most expensive deal in sports history.
