Michael Bloomberg Claims Top Philanthropy Spot for Third Straight Year
Michael Bloomberg has secured the number one position on the Chronicle of Philanthropy's prestigious Philanthropy 50 list for the third consecutive year. The founder of Bloomberg LP and former mayor of New York City donated an impressive $4.3 billion in 2025 to support arts, education, environmental initiatives, public health programs, and efforts to enhance city governance.
Billion-Dollar Donors Follow Close Behind
Following Bloomberg on the exclusive ranking are three philanthropists who each contributed $1 billion or more to charitable causes last year. Bill Gates, occupying the second spot, donated $3.7 billion to the Gates Foundation. The late Paul Allen, co-founder of Microsoft, left a substantial $3.1 billion bequest to establish a foundation dedicated to science and technology. Warren Buffett contributed $1.3 billion to four family foundations supporting diverse causes.
Collectively, the donors featured on the Philanthropy 50 list contributed a remarkable total of $22.4 billion to charity in 2025. The median gift amount stood at $105 million, highlighting the substantial scale of these philanthropic efforts.
Wealth Sources and Geographic Distribution
The financial industry emerged as the primary source of wealth for most donors on the list, with twenty philanthropists from this sector giving a combined $4.1 billion. The technology sector followed closely, with twelve donors contributing $10 billion. Real estate represented the third-largest sector, with four donors providing $466.7 million.
Geographically, more donors reside in New York and California than in any other states, and nonprofits located in these regions received the highest volume of gifts.
Personal Motivations Behind Major Giving
For many donors, philanthropy provides profound personal meaning. Jon and Mindy Gray, ranked thirty-fourth with a donation of $63.6 million, primarily support research on inherited cancers related to BRCA mutations, a cause close to their hearts following the loss of Mindy's sister to BRCA-related ovarian cancer at age forty-four. They also focus on empowering young people in New York City through initiatives like the Gray Scholars program, which provides scholarships to ten students annually to attend historically Black colleges or universities.
"We're very hands-on people—we enjoy it," Mindy Gray explains. "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."
Despite such inspiring examples, only nineteen of the wealthiest Americans on the Forbes 400 list donated sufficiently to appear in this year's rankings. Notably, high-profile philanthropist MacKenzie Scott, who has donated approximately $26 billion to charities since 2020, does not appear on the list. It is likely that Scott made gifts through donor-advised funds that would have qualified her for inclusion, but she and her representatives declined to provide detailed information about these contributions.
Long-Term Relationships Drive Significant Donations
Not all donors on the Chronicle's list attract widespread media attention for their giving. Several lesser-known philanthropists made substantial contributions based on enduring relationships with charitable organizations.
- Robert and Karen Hale (Ranked 25th): The founder of Granite Telecommunications and his wife donated nearly $111 million last year to dozens of nonprofits they have supported for years. This included a $100 million gift to Boston Children's Hospital and additional funds to education, human-service, social-justice, and youth groups throughout the greater Boston area.
- James and Patricia Anderson (Ranked 39th): This automotive consultant and his wife gave $50 million to Wayne State University, his alma mater, along with more than $8 million to charities serving the elderly and individuals with special needs.
- Melanie and Richard Lundquist (Ranked 42nd): Los Angeles real estate investors and longtime supporters of Southern California nonprofits donated $50 million to Torrance Memorial Medical Center and $3 million to organizations assisting cancer patients and young people.
The Chronicle's research indicates that more than thirty-five of the fifty-one donors on the list maintained long-term relationships, often spanning five to ten years or more, with the charities receiving their largest gifts in 2025.
"It's about building relationships," says Jeff Schreifels, a fundraising consultant at Veritus Group. "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."
Diverse Causes Benefit from Philanthropic Support
Foundations, donor-advised funds, colleges, and universities were the primary recipients of last year's gifts. However, donors also supported a wide variety of causes, including:
- Science and Technology: Received over $3 billion, including Paul Allen's bequest and a $60 million donation to support the quantitative science program at the University of Pennsylvania's Wharton School.
- Healthcare and Medical Research: Garnered a total of $1.5 billion, featuring a $500 million donation from Nike co-founder Phil Knight and his wife Penny for cancer research and treatment, multiple eight- and nine-figure gifts for pediatric healthcare, and two contributions supporting dementia research and care.
- Athletics: Received $871 million, including two separate $300 million donations for university athletics and a $100 million gift to provide financial aid to Olympic athletes.
These philanthropic efforts demonstrate that while billionaires and millionaires donate enormous sums, their motivations often align with those of everyday donors: a desire to support causes they are passionate about, collaborate with effective organizations, and contribute to people and charities they have trusted for years.
