The deal surpassed the sale of the NFL’s Washington Commanders in 2023, which came in at $6.05 billion.
The team was previously owned by the Grousbeck family, who bought it for $360 million, and they’ve agreed to sell it to Chisholm, who is a co-founder of Symphony Technology Group.
“This was an extremely thorough, rigorous sale process,” the Grousbecks said. “We had tremendous interest from potential control owners and we’re grateful for the considerable time and effort bidders put in over the past few months, especially. In the end, Bill and the group he put together came in with a superior final bid.”
