A source just dropped the news to the Associated Press: a group led by William Chisholm, co-founder and managing partner of Symphony Technology Group, has agreed to buy the Boston Celtics for a jaw-dropping $6.1 billion. If this deal goes through, it’ll officially be the *largest sale ever* in U.S. professional sports history, smashing the previous record set by the Washington Commanders’ $6.05 billion sale in 2023.
The details are still a bit hazy—like when exactly the deal will close and how it’s structured—but one thing’s clear: this is HUGE. Boston Basketball Partners LLC, the current ownership group, had been planning to sell the majority of their Celtics shares by early this year, with the rest to follow in 2028. Current governor Wyc Grousbeck will stay on board until the sale is finalized.
So, who’s the man behind the deal? William Chisholm isn’t just any billionaire—he’s a tech investment powerhouse. As the co-founder, managing partner, and chief investment officer of Symphony Technology Group, he’s got serious chops from his time at Bain & Company and PaineWebber. With a net worth rumored to be in the tens of millions (and likely climbing), Chisholm is stepping into the NBA world in a major way.
The Celtics’ legacy just got a whole lot richer—literally. Stay tuned for more updates as this historic deal unfolds!
