The Boston Celtics, one of the most storied franchises in NBA history, have officially been sold for a record-breaking $6.1 billion. This sale surpasses the previous record set by the Washington Commanders in the NFL ($6.05 billion) and solidifies the Celtics as one of the most valuable teams in professional sports.
Who Bought the Celtics?
William “Bill” Chisholm is a prominent private equity executive with deep ties to Massachusetts and a lifelong passion for the Boston Celtics.
Chisholm and his investment team are acquiring the franchise from Wyc Grousbeck, who has been the majority owner since 2002.
Under the terms of the sale, Grousbeck will remain as the team’s governor through the 2027-28 season, ensuring continuity in leadership while the new ownership settles in.
Early Life and Education
- Chisholm grew up in Georgetown, Massachusetts, where his father, William F. Chisholm Sr., played a pivotal role in establishing the Georgetown High School soccer program. He attended Dartmouth College, graduating in 1991, and later earned an MBA from the Wharton School of the University of Pennsylvania. During his time at Dartmouth, Chisholm was an active member of the soccer team. Wikipedia
Professional Career
- Chisholm’s career began in technology investing and investment banking. He worked with Boston-based Bain & Company and the investment bank PaineWebber. In 2002, he co-founded Symphony Technology Group (STG), a private equity firm specializing in technology and software investments.

Under his leadership, STG has managed over $10 billion in assets and executed over 100 investments, including notable acquisitions like cybersecurity firm Trellix. AP News
A Look Back at Wyc Grousbeck’s Legacy
Grousbeck purchased the Celtics in 2002 for $360 million—a figure that seems minuscule compared to today’s sale price. Over his two-decade tenure, the Celtics:
- Won two NBA championships (2008, 2024)
- Became one of the most profitable teams in the NBA
- Increased their valuation nearly 17 times
- Built a sustainable winning culture
The 2024 championship victory, led by Jayson Tatum and Jaylen Brown, was a perfect sendoff for Grousbeck’s ownership era, cementing his legacy as one of the most successful owners in franchise history.
Why Did the Celtics Sell for So Much?
Several key factors contributed to the Celtics’ record-setting price tag:
- On-Court Success – Fresh off their 2024 NBA title and another strong season, the Celtics remain one of the league’s elite teams.
- Massive Market & Fan Base – Boston has a loyal and historic fanbase, making the team highly attractive to investors.
- NBA’s Explosive Growth – With rising global revenues, lucrative TV deals, and increasing franchise values, NBA teams have never been hotter assets.
- The Future of the Celtics – Young stars like Jayson Tatum and Jaylen Brown ensure the team’s competitiveness for years to come.
What’s Next for the Celtics?
Fans will be eager to see how Chisholm and his ownership group operate. Will they invest even more into the roster? Will there be any changes to the Celtics’ front office?
For now, Celtics fans can take pride in knowing their team remains one of the most valuable and successful franchises in all of sports.
