MacKenzie Scott’s Philanthropy in 2025
MacKenzie Scott’s $7 billion donation in 2025 made her the largest single donor in the U.S. That year, she accounted for one-third of the $19.2 billion in megagifts. Her giving, spread across thousands of organizations, focused on housing, diversity, and disaster recovery. Despite her generosity, she remained under the radar, avoiding media attention and not disclosing details of her donations. The U.S. philanthropy sector saw a 5.7% increase in 2025, reaching $617.2 billion, according to a report by Giving USA and Indiana University.
Other Major Donors in 2025
Michael Bloomberg gave $4.3 billion, Bill Gates $3.7 billion, and Warren Buffett $1.34 billion. The Dell family donated nearly $1 billion. These donations were part of a broader trend of increased giving in the U.S. The report highlighted that most categories of charitable organizations saw growth. Religious, human services, education, health, and arts organizations received the most funding. Despite the overall growth, Scott was not listed on the Chronicle of Philanthropy’s top 50 donors, due to her preference for privacy.
Scott’s Motivation and Background
Scott’s giving was inspired by past acts of kindness, such as a $1,000 loan from her college roommate and free dental care from a dentist. She emphasized the long-term impact of small, non-transactional acts of generosity. In a December 2025 essay, she wrote about the psychological benefits of giving, noting that it activates the same pleasure centers in the brain as sex, food, and receiving gifts. She also signed the Giving Pledge, promising to give away the majority of her net worth. Her Amazon shares, received after her divorce from Jeff Bezos, kept her net worth at nearly $37 billion.
Scott’s Privacy and Public Recognition
Despite her massive donations, Scott avoided public recognition. The Chronicle of Philanthropy did not list her on its top 50 donors, as she and her representatives declined to provide details. She rarely speaks publicly about her giving, preferring to let the impact of her donations speak for themselves. Her quiet approach contrasts with other philanthropists who seek media attention. However, her influence on the philanthropy landscape is undeniable, as she has given more in a single year than many billionaires have in their lifetimes.
Scott’s Future and Impact
Scott’s $26.2 billion in total giving over five years has had a significant impact on thousands of organizations. Her approach to philanthropy emphasizes trust and autonomy, allowing recipients to use the funds as they see fit. She has also ventured into writing, releasing a novel that is not available on Amazon. Her continued generosity, combined with her privacy, sets her apart in the world of philanthropy. While she may not seek recognition, her impact on the sector is clear, and her legacy is likely to grow in the years to come.
