Celtics owners give Boston Children’s Hospital a record $200 million, the biggest statement yet from Bill Chisholm’s $6.1 billion group

The biggest number the Celtics posted this week did not come from Jayson Tatum. On Thursday, Oct. 29, Boston Children’s Hospital announced a gift of more than $200 million from the Celtics ownership group and the team, in association with the Celtics’ Shamrock Foundation. It is the largest donation in the hospital’s history.

It is also the clearest public statement yet from the group led by Bill Chisholm, which took control of the franchise in 2025 after putting together a bid that valued the Celtics at $6.1 billion, a record for a North American team at the time.

“The Celtics have historically been defined by the concept that true legacy is more than what happens on the court,” Chisholm said in a statement. “Boston Children’s and the Celtics share a belief that it takes every single one of us to achieve our most ambitious goals. This gift is our commitment to the next generation in Boston and far beyond. We all win when we invest in our children’s futures.”

How the $200 million was built

The gift was not written as one check. Half of it is the $100 million that co-owner Rob Hale and his wife, Karen, pledged in December 2025 to build a new pediatric behavioral health campus in Boston’s Brighton neighborhood. At the time, that was already the largest gift Boston Children’s had ever received.

The rest of the ownership group, about two dozen investors, then set out to match it. Hale said two owners started by giving $10 million each earlier this year, and the total from the others quickly grew to $60 million before it reached the full $100 million. Neither the team nor the hospital disclosed what each owner gave.

The group includes private equity firm Sixth Street, Chisholm, Hale, steel executive Aditya Mittal, Klaviyo co-founder Andrew Bialecki and New York real estate developer Bruce Beal Jr. Chisholm, who grew up on Boston’s North Shore, made his fortune as co-founder of the private equity firm STG Partners.

“I’ve had the privilege of seeing firsthand the extraordinary work being done at Boston Children’s Hospital and the difference it makes for patients and families,” Hale said.

Where the money goes

The hospital listed five priorities. The first is the Brighton campus, a $640 million project on the grounds of Franciscan Children’s that broke ground on Oct. 8. Its first phase is a 116-bed pediatric psychiatric hospital that will nearly double Boston Children’s inpatient psychiatric capacity, and it is expected to open in 2029.

The other four are research into new therapies for childhood diseases and the early origins of adult diseases, advanced training for pediatric nurses, an innovation fund for what the hospital called “daring concepts” in children’s health, and family programs that promote healthy lifestyles.

“While the size of this gift is unprecedented for Boston Children’s Hospital, its significance will ultimately be measured not by the record it sets, but by the lives it will save,” said Dr. Kevin Churchwell, the hospital’s CEO. Boston Children’s president Dr. Ryan Nagy added in a radio interview that the money is especially timely because federal health and research funding has become less predictable.

On the same day, the Celtics hosted a group of the hospital’s patients at practice, where Mike Conley handed out chest bumps for made shots.

What it means in business terms

For scale, $200 million is about 3% of the price the Chisholm group agreed to pay for the team. It is close to the roughly $198 million the Red Sox have raised for the Dana-Farber Cancer Institute’s Jimmy Fund over several decades, and it is about 27 times what the Shamrock Foundation gave out last year, when it sent roughly $7.5 million to about 500 nonprofits across New England. The team said the new gift does not replace that annual giving.

It also sits completely outside the salary cap. Money that owners give to charity is not player salary, so it does not count toward the luxury tax or the aprons, and it has no effect on how much the Celtics can spend on their roster. That matters because the new owners’ first summer was defined by cost-cutting. The front office traded Jrue Holiday and Kristaps Porzingis in 2025 to bring the payroll down and get below the second apron, the line that comes with the league’s harshest spending penalties.

Big civic gifts are also part of how a new ownership group builds a public profile, and the price of that profile keeps rising. Team values have climbed so fast that the Lakers deal set a $12.5 billion mark, the stock market now values the Knicks at about $7.35 billion, and the league has told Las Vegas bidders an expansion team will cost $10 billion or more. As purchase prices rise, so does the wealth of the people sitting in owners’ suites.

The Celtics have a long record here. The previous ownership group led by Wyc Grousbeck, Steve Pagliuca and Robert Epstein launched the Shamrock Foundation in 2004, and in 2020 the team committed $25 million to fight racial injustice and support Black communities. The franchise that drafted the NBA’s first Black player, Chuck Cooper, in 1950 and hired its first Black head coach, Bill Russell, in 1966 has long tied its brand to more than wins.

What to watch

On the court, Jayson Tatum followed his return from a torn Achilles with a 40-point overtime winner against Brooklyn this week. Off it, the next steps are concrete: construction on the Brighton campus, the first grants from the innovation and research funds, and whether other NBA ownership groups answer with gifts of their own. Boston’s owners have set the bar at $200 million.
