Something is shifting in the way the world thinks about wealth. Being used to mean accumulating, protecting, and growing. Now, for a growing number of the world’s wealthiest people, the most powerful statement they can make is not how much they own, but how much they give away. This isn’t charity in the old-fashioned sense. It’s a full-scale rethinking of what it means to have money and what responsibility comes with it.
A Record-Breaking Year for American Generosity
Individuals, bequests, foundations, and corporations gave an estimated $592.50 billion to U.S. charities in 2024, making it the most generous year in recorded American history. Giving to U.S. charities in 2024 reached an estimated $592.5 billion, representing a growth of 6.3% in current dollars and a new high. What drove this surge? Financial and economic security are key determinants of philanthropic giving, and major economic indicators, including GDP growth, stock market performance, and increased disposable income, pointed toward a return to meaningful growth in 2024.
Record giving creates opportunity: with $592.5 billion in 2024 charitable giving, individuals contributed 66% of total donations. That’s not a small number of mega-donors skewing the picture either. Individual donors remain the backbone of American philanthropy, contributing two-thirds of all charitable dollars. For the first time in three years, total giving outpaced inflation, with growth in total giving in 2024 similar to the 40-year averages of 5.5% in current dollars and 2.7% adjusted for inflation.
The Giving Pledge and the Ultra-Wealthy
Warren Buffett, Bill Gates, and Melinda French Gates started the Giving Pledge in 2010 to persuade the world’s wealthiest people to commit to giving at least half of their fortunes to charity. Over a decade later, the pledge has grown considerably. As of October 2025, the pledge has more than 250 signatories from 30 countries, with most of the signatories being billionaires, at a total pledged wealth of US$600 billion. The numbers behind individual donors on this list are staggering. For the fifth consecutive year, Warren Buffett and his family topped the list in terms of total giving, with $62 billion over his lifetime representing 30% of his net worth, and he donated more in the past year than anyone else, a total of $5.3 billion.
Still, scrutiny of the pledge reveals a complicated picture. According to a 2025 analysis by the Institute for Policy Studies, the 32 original U.S. pledgers who remain billionaires have collectively become about 166% wealthier since signing on in 2010. Only one set of the 2010 signers still living, Laura and John Arnold, have actually exceeded giving more than 50% of their assets away during their lifetimes. The gap between pledging and actually giving remains one of the most debated topics in modern philanthropy.
MacKenzie Scott and the Rise of Trust-Based Giving
Billionaire philanthropist MacKenzie Scott had a banner year in 2025: she donated $7.2 billion, bringing her cumulative philanthropic giving through her organization, Yield Giving, to an eye-popping $26 billion across more than 2,700 gifts in just the past five years. Her approach is unlike anything the world of philanthropy has seen before. Scott’s style of giving upends the traditional philanthropic playbook. She writes few press releases, operates without a large foundation staff, and gives primarily through a model known as trust-based philanthropy. The approach allows recipients to decide for themselves how best to use the funds, without the usual strings or reporting requirements attached.
Her 2025 donations continue her signature approach: large, unrestricted grants given without lengthy applications or reporting requirements. This model, built on trust and aimed at reducing administrative burdens, has distinguished her from traditional philanthropic practices and positioned her as a transformative force in modern giving. The ripple effects are being felt across the nonprofit sector. Scott’s giving has undoubtedly served as a signal of credibility and sophistication, making recipient organizations worthy of additional investment from other high-net-worth philanthropists and institutions. More philanthropists are echoing her giving and making more substantive and less restricted gifts. Further, Scott’s philanthropic strategy has sparked a shift toward dynamic giving to meet the needs of the moment by funding nonprofits working on the frontlines.
The Great Wealth Transfer and the Next Generation of Donors
The Great Wealth Transfer represents the largest intergenerational wealth shift in history, with $124 trillion moving over 25 years and $85 trillion specifically flowing to Millennials and Gen Z. This shift is already changing the face of charitable giving. Millennial participation in giving has increased 16% and Gen Z participation has grown 22% since 2021. Some estimates indicate that $18 trillion will go to charity by 2048, creating the opportunity for next-generation donors to have a significant charitable impact in the future.
Wealthy millennials and Gen Zers are redefining the world of charitable giving, seeing themselves more as activists than donors. Wealthy donors under the age of 43 are more likely to volunteer, fundraise, and act as mentors for charitable causes rather than just give money, according to a survey from Bank of America Private Bank. Their cause priorities are shifting too. They’re twice as likely to support efforts related to homelessness, social justice, climate change, and the advancement of women and girls. Bank of New York Mellon reports that 97% of millennials consider charitable giving part of their overall wealth strategy.
Where the Money Is Actually Going
Four subsectors reached all-time highs in 2024: education, health, environment and animals, and arts, culture and humanities. The biggest single-year jump was in civic causes. The largest year-over-year increase in giving was directed to public-society benefit causes, with 19.5% growth. This subsector includes organizations that focus on civil rights, community development and advocacy, and grantmaking foundations. Corporate giving also had a strong year. Corporate philanthropy rose 9.1%, a strong showing, though still representing only 7% of total giving.
Religious giving, meanwhile, continues a long historical decline. Religion continues to receive the largest share of charitable dollars, totaling an estimated $146.54 billion in 2024. However, religion’s overall share of total giving has steadily declined over time, from 62% in 1984 to just 23% in 2024. This shift redirects billions toward secular causes, creating opportunities for nonprofits in education, health, environment, and social services. The composition of American generosity is not just growing in dollar terms but changing in character.
Women Are Reshaping the Face of Philanthropy
Charity specialists have pulled on a common thread of who is innovating philanthropy, and how the general makeup of mega-donors is changing: women are in the spotlight. With more than 200 new billionaires minted in 2024 alone, nearly four every week, more players are entering the field and some women are stepping into immense wealth. The status quo of philanthropy is changing, and women are front and center. Melinda French Gates left the Gates Foundation in 2024 and now runs Pivotal Ventures, a group of philanthropic organizations focused on women’s issues. In 2024, she committed $150 million to create professional opportunities for women, with a third focused on the AI industry.
Michael Bloomberg has donated more than $21 billion to charitable causes and has ranked as America’s most generous donor in 2024 and 2025, with donations of $3 billion and $3.7 billion respectively over a twelve-month period. Yet it is Scott who has captured the most attention for her scale and speed. Scott’s cumulative giving places her behind only Warren Buffett and Bill Gates in terms of lifetime charitable contributions, according to Forbes. In 2024, 43% of affluent individuals volunteered their time and talents to charitable organizations, up from 37% in 2022, according to the Bank of America Study of Philanthropy. Across genders and generations, the wealthy are not just writing checks. They are showing up.
