William Chisholm Acquires Majority Stake in Boston Celtics for Record $6.1 Billion

Boston, Massachusetts — William Chisholm, managing director and co-founder of Symphony Technology Group, has acquired a 51% stake in the Boston Celtics, making headlines as the deal was finalized for a historic price of $6.1 billion. This acquisition marks the largest sum ever paid for a sports team in North America, surpassing the previous record held by Josh Harris‘s $6.05 billion purchase of the Washington Commanders.
The Celtics’ ownership group, led by Wyc Grousbeck, confirmed the sale in a statement issued Thursday. Chisholm, a native of Georgetown, Massachusetts, attended Dartmouth College and has been a lifelong supporter of the Celtics. This transition comes several months after the Grousbeck family announced their intention to sell the team, citing estate and family planning reasons.
Chisholm will take over the franchise amid its continued success. The Celtics, who secured their 18th NBA title last June, are currently boasting an impressive 50-19 record this season, positioning them as strong contenders for another championship.
“I look forward to being part of this incredible organization,” Chisholm said in a statement. “The Boston Celtics have a storied history and a dedicated fanbase, and I’m excited to keep building on what Wyc and his team have established.”
Wyc Grousbeck is set to remain as the team’s governor during the transition. He expressed confidence in Chisholm as the new steward of the Celtics, emphasizing the importance of maintaining the club’s competitive edge. Grousbeck noted, “We’re excited about what this means for the team. We believe in the vision and leadership William brings.”
The Celtics’ financial outlook is notable; with a talented roster featuring All-Stars like Jayson Tatum and Jaylen Brown, they face substantial costs. The team has incurred a luxury-tax bill exceeding $50 million this season, which could escalate significantly if changes are not implemented in payroll structure for the next season.
“We’re prepared to address the challenges ahead, including the payroll and luxury tax implications,” Chisholm added. “My focus will be on not just competing at the highest level but ensuring the long-term financial stability of the organization.”
Current players, including Tatum, have expressed hopes that the new ownership will preserve the stability and culture the team has built. “I trust they’ll make the right decisions,” Tatum stated, highlighting the importance of continuing the organization’s legacy and success.
The milestone purchase reflects a broader trend of increasing valuations in professional sports franchises, fueled by rising revenues and demand for sports entertainment. As the NBA market expands, the Celtics’ record sale is indicative of the franchise’s ongoing significance within the league.
League approval is still pending for Chisholm’s ownership. In the interim, the Celtics are focused on their playoff push, bolstered by historical performance and community support, as they aim for another championship run amidst the evolving landscape of professional basketball.
