MacKenzie Scott reinforced her position as one of the world’s most generous philanthropists in 2025 after donating around $7 billion to charitable causes across the United States. According to Giving USA and the Indiana University Lilly Family School of Philanthropy, Scott’s contributions accounted for nearly one-third of the country’s $19.2 billion in major charitable gifts made during the year. The donations formed part of a record year for US philanthropy, which reached $617.2 billion overall. Despite making the largest charitable contribution of any individual donor in 2025, Scott continued her long-standing approach of giving quietly, avoiding publicity while supporting thousands of organisations working across a wide range of causes.
MacKenzie Scott was America’s biggest donor in 2025
MacKenzie Scott emerged as the largest individual philanthropist in the United States in 2025 after donating approximately $7 billion. Her giving represented about one-third of the $19.2 billion in major charitable gifts made during the year. Other leading donors included Michael Bloomberg, who contributed $4.3 billion, Bill Gates with $3.7 billion, Warren Buffett with $1.34 billion, and Susan and Michael Dell, who donated nearly $1 billion. Scott’s cumulative charitable giving has now reached approximately $26.2 billion over the past five years.According to the Giving USA Annual Report on Philanthropy, Americans donated an estimated $617.2 billion to charity in 2025, marking a 5.7 per cent increase from the previous year after adjusting for inflation. The total includes donations from individuals, foundations, corporations and charitable bequests. Among the sectors receiving the greatest support were religion, education, human services, health, international affairs, arts and culture, reflecting broad growth across nearly every category of charitable organisations.
Why MacKenzie Scott was missing from the Philanthropy 50 list
Despite donating more than any other individual during the year, Scott did not appear on the Chronicle of Philanthropy’s annual Philanthropy 50 ranking. The publication explained that its rankings rely on publicly available information and voluntary disclosures. Scott and her representatives declined to provide details about donations made through donor-advised funds, making it impossible to determine whether those gifts qualified under the publication’s methodology. As a result, she was excluded despite her substantial charitable contributions.
A different approach to philanthropy
Since announcing her commitment to philanthropy following her 2019 divorce from Amazon founder Jeff Bezos, Scott has adopted an unconventional approach to charitable giving. Rather than requiring lengthy applications or imposing detailed conditions, she often provides unrestricted grants, allowing recipient organisations to decide how best to use the funds. Her donations have supported thousands of non-profit organisations working in areas such as affordable housing, education, racial equity, disaster recovery, public health and community development.
What motivates MacKenzie Scott’s giving?
Scott has repeatedly said that her philanthropy is driven by personal experiences and the kindness she received earlier in life. In an essay published in December 2025, she recalled how a college roommate once lent her $1,000 so she could remain enrolled, while a dentist provided treatment free of charge when she could not afford it. She wrote that such acts of generosity can create lasting ripple effects and argued that non-transactional kindness is often underestimated despite its long-term social benefits. Scott also noted that scientific research suggests generosity and kindness contribute to greater happiness and improved wellbeing.
The Giving Pledge and her growing legacy
Following her divorce, Scott signed the Giving Pledge, a commitment created by Bill Gates, Melinda French Gates and Warren Buffett that encourages billionaires to donate the majority of their wealth during their lifetimes or through their estates. Although Scott has already donated more than $26 billion, the appreciation of her Amazon shares means her estimated net worth remains close to $35 billion. Her continued philanthropy has made her one of the most influential charitable donors of the modern era, setting a benchmark for large-scale, trust-based giving without seeking public recognition.
