Overview

  • William Chisholm, managing partner of Symphony Technology Group, leads the new ownership group, which includes private equity firm Sixth Street and local investors Rob Hale and Bruce Beal Jr.
  • The $6.1 billion deal surpasses the $6.05 billion sale of the Washington Commanders in 2023, setting a new record for a U.S. sports franchise.
  • The Grousbeck family, owners since 2002, will remain in charge of team governance until 2028 as part of a phased transition plan.
  • The Celtics, reigning NBA champions with 18 titles, were sold following a surge in franchise valuations driven by lucrative media rights deals and private equity investments.
  • The sale excludes TD Garden, the team's home arena, though the Celtics' lease there extends through the 2035-36 season.
