Boston Celtics Enter New Era as Bill Chisholm Completes Record-Breaking $6.1 Billion Ownership Deal.

The Boston Celtics, one of the most storied franchises in professional sports, are embarking on a new chapter following a historic change in ownership. Private equity billionaire Bill Chisholm, a lifelong Celtics supporter, has officially purchased the majority stake in the team for $6.1 billion, marking one of the largest franchise sales in NBA history. The deal, unanimously approved by the NBA’s Board of Governors, is set to gradually shift full control to Chisholm by 2028.

This landmark transaction not only underscores the Celtics’ unmatched legacy in basketball but also reflects the skyrocketing value of professional sports franchises in recent years. With 17 NBA championships and a global fan base that stretches across continents, the Celtics remain one of the league’s crown jewels.

Private equity mogul Bill Chisholm—a lifelong Celtics fan—has officially acquired majority ownership of the team in a historic $6.1 billion deal, approved unanimously by the NBA. He’s poised to assume full control by 2028, pledging to uphold the franchise’s pursuit of championships. Former owner Wyc Grousbeck remains involved to ensure continuity.

Continuity Amid Change

Though Chisholm will be assuming majority control, outgoing governor Wyc Grousbeck will remain involved during the transition period. Grousbeck, who helped oversee Boston’s resurgence into perennial contenders over the past two decades, expressed confidence in the team’s future.

“Bill’s passion for the Celtics and his commitment to excellence ensure that the franchise remains in great hands,” Grousbeck said in a statement. “It’s a bittersweet moment for me, but I’m thrilled for what’s ahead for the team and our fans.”

Chisholm, meanwhile, emphasized his deep personal connection to the franchise. “The Celtics are more than just a basketball team to me—they represent tradition, pride, and community,” he said. “I grew up watching them, and now I have the honor of helping carry that legacy forward. Our mission remains clear: to compete for championships year in and year out.”

Impact on the Team’s Future

The Celtics’ sale comes at a pivotal moment for the franchise. After celebrating a successful 2024–25 campaign, the team now faces the challenge of navigating through roster changes and the long-term recovery of star forward Jayson Tatum, who is sidelined with an Achilles injury.

With Chisholm’s backing, however, there is optimism that Boston will continue to invest heavily in player development, infrastructure, and global brand growth. His background in private equity suggests a focus on long-term sustainability while maintaining the competitive spirit that Celtics fans demand.

Industry analysts note that this sale cements the Celtics as one of the most valuable sports organizations in the world, alongside franchises like the New York Knicks, Los Angeles Lakers, and Dallas Cowboys.

While fans may not notice immediate changes on the court, the symbolic passing of ownership marks the beginning of a new era. Chisholm has pledged not to interfere with basketball operations but to provide the resources needed for the front office and coaching staff to succeed.

For Celtics Nation, the message is clear: the team’s commitment to chasing championships remains as strong as ever. With fresh leadership at the helm, Boston looks poised to continue its pursuit of an 18th banner to hang from the rafters of TD Garden—an achievement that would solidify its place as the winningest franchise in NBA history.
