Summary
MacKenzie Scott's philanthropic activity in 2025 underscores the concentration of charitable giving among ultra-high-net-worth individuals in the United States. Scott's $7 billion in donations last year accounted for exactly one-third of all American megagifts totaling $19.2 billion, according to data from Giving USA and the Indiana University Lilly Family School of Philanthropy. This single year of giving brought her cumulative five-year philanthropic total to $26.2 billion, distributed across thousands of organizations with a focus on housing, diversity and equity initiatives, disaster recovery, and other social causes.

The scale of Scott's giving substantially outpaces other prominent megadonors. Michael Bloomberg contributed $4.3 billion in 2025, while Bill Gates donated $3.7 billion, Warren Buffett gave $1.34 billion, and Susan and Michael Dell contributed nearly $1 billion. Collectively, these five donors accounted for approximately $18 billion of the $19.2 billion in megagifts, demonstrating the degree to which ultra-wealthy individuals shape the philanthropic landscape.

The broader U.S. charitable sector recorded strong growth in 2025, with total donations reaching $617.2 billion—a 5.7% increase from 2024. This aggregate figure includes contributions from individuals, bequests, foundations, and corporations. According to Gabe Cooper, vice chair of Giving USA Foundation, "It was a positive year for charitable giving, with virtually all categories of recipient organizations achieving solid or better growth at the aggregate level." Religious institutions, human services, education, health, international affairs, and arts and culture were among the largest beneficiary categories.

Despite her record-setting philanthropic year, Scott was notably absent from the Chronicle of Philanthropy's list of top 50 donors for 2025, a reflection of her deliberate approach to maintaining privacy around her giving. Scott, the ex-wife of Amazon founder Jeff Bezos, has consistently prioritized anonymity in her charitable work, choosing to allow her donations to speak through recipient organizations rather than seeking public recognition.
