Private equity investor Bill Chisholm is still working hard while leading a group that agreed to purchase the Boston Celtics last week for a record $6.1 billion evaluation. Chisholm, a life-long Celtics fan and Massachusetts native already has several partners in the deal including current Celtics minority co-owner Robert Hale, Bruce A. Beal Jr, and Sixth Street, a global investment firm, among others. It’s unclear what the specific stakes those individuals will have in the eventual Celtics purchase but Axios has reported that Sixth Street’s investment could be as much as a billion dollars.

Despite those hefty investments, a report from Forbes indicates that Chisholm was still on the hunt for more investors in the deal as recently as last week. A billionaire told Forbes in the story that they were offered an opportunity to buy a stake in the team as recently as last Thursday, the same day the purchase was announced.

Ultimately, Chisholm’s group will take a controlling stake in the franchise once the deal is closed this summer, pending approval by the league. Chisholm agreed to let current CEO, team governor and co-owner Wyc Grousbeck remain in his current role until the final close of the sale in 2028.

“My partners and I have immense respect for Wyc, the entire Grousbeck family and their indelible contributions to the Celtics organization over the last 23 years,” Chisholm said in a release last week announcing the sale. “We look forward to learning from Wyc and partnering with Brad Stevens, Joe Mazzulla and the talented team and staff to build upon their success as we work to bring more championships home to Boston.”

Chisholm has indicated he plans to attend the Celtics’ April 2nd matchup against the Miami Heat at TD Garden, the team’s first home game since the sale agreement was announced.
