For the third consecutive year, Michael Bloomberg landed the No. 1 spot on the Chronicle of Philanthropy’s exclusive ranking of the 50 biggest donors of 2025. The founder of the Bloomberg financial-news empire and former New York mayor gave $4.3 billion to support arts, education, the environment, public health, and programs to improve city governments.
Bloomberg is followed on the Philanthropy 50 list by three donors who each gave $1 billion or more to charity last year. Bill Gates (No. 2) gave $3.7 billion to the Gates Foundation, and his former Microsoft colleague, the late Paul Allen (No. 3), left a $3.1 billion bequest to start a foundation focused on science and technology. Warren Buffett donated $1.3 billion to four family foundations that support a range of causes.
Together the donors on the Philanthropy 50 list contributed a total of $22.4 billion to charity in 2025. The median gift was $105 million.
The financial industry was the source of wealth for most donors on the list, with 20 philanthropists giving a total of $4.1 billion. Next was technology, with 12 tech donors contributing $10 billion, and then real estate, with four donors giving $466.7 million.
More donors live in New York and California than any other state, and nonprofits in those states received the most gifts.
For many of these donors, philanthropy brings them great meaning. Jon and Mindy Gray (No. 34, at $63.6 million) primarily support research on inherited cancers related to BRCA mutations — Mindy’s sister died of BRCA-related ovarian cancer at age 44 — and empowering young people in New York City. One of their initiatives, the Gray Scholars program, provides scholarships to 10 New York City students per year to attend a historically Black college or university. Every year, the Grays participate in a gathering for all the scholars.
“We’re very hands-on people — we enjoy it,” Mindy Gray says. “Other people often come to us and say, ‘I want to do something, but what should I do?’ And it really is what you feel in your heart. You should not be doing this work in areas that don’t move you.”
But few of the country’s wealthiest people are moved to give in the way that the Grays and other Philanthropy 50 donors do. Only 19 of the richest Americans on the Forbes 400 list donated enough to appear in this year’s rankings.
High-profile philanthropist MacKenzie Scott is not in the ranking, though she has donated some $26 billion to charities since 2020. It is likely that Scott made gifts to her donor-advised funds that would have earned her a spot in the ranking, but she and her representatives declined to provide information about how much money she is funneling to the grantmakers.
Long-term relationships yield big donations
Not all donors on the Chronicle’s list grab headlines for their giving. Some lesser-known philanthropists who landed on the Philanthropy 50 include:
— Robert and Karen Hale (No. 25): The Granite Telecommunications founder and his wife gave nearly $111 million last year to dozens of nonprofits they have supported for years. They gave a $100 million gift to Boston Children’s Hospital and the remainder to education, human-service, social-justice, and youth groups throughout the greater Boston area.
— James and Patricia Anderson (No. 39): The automotive consultant and his wife gave $50 million to Wayne State University, his alma mater, and more than $8 million to charities that serve the elderly and people with special needs.
— Melanie and Richard Lundquist (No. 42): The Los Angeles real estate investors are longtime donors to Southern California nonprofits, primarily backing health care and the city’s public schools. Along with a $50 million donation they gave Torrance Memorial Medical Center, they also donated $3 million to nonprofits that help cancer patients and young people.
Though these billionaires and millionaires give away huge sums, they give for many of the same reasons that everyday donors do. They are drawn to groups that seek their input, understand their passions, are open to collaboration, and have effective programs. Most important, they give to people and charities they have known and trusted for years, if not decades.
The Chronicle found that more than 35 of 51 donors on the list had long-term relationships, often lasting five to 10 years or more, with the charities to which they gave the most in 2025.
“It’s about building relationships,” says Jeff Schreifels, a fundraising consultant at Veritus Group, which works with both large and small charities. “It’s being that bridge between the donor and their desire to change the world and matching that up with everything that the nonprofit does. That’s what everyone is trying to do.”
Variety of causes
Foundations and donor-advised funds created by the donors and colleges and universities were the biggest recipients of last year’s gifts. But many donors also supported a diverse range of causes that included:
Science and technology, which received more than $3 billion, including Allen’s big bequest and a $60 million donation to support the quantitative science program at the University of Pennsylvania’s Wharton School.
Health care and medical research, which got a total of $1.5 billion, including a $500 million donation from Nike co-founder Phil Knight and his wife, Penny, for cancer research and treatment; a number of eight- and nine-figure gifts to back pediatric health care; and two gifts to support dementia research and care.
Athletics, which received a total of $871 million, including two donations of $300 million apiece for university athletics and a $100 million gift to provide financial aid to Olympic athletes.
