MacKenzie Scott donated $26 billion over the past seven years, including a record $7.2 billion in 2025, a pace of giving that makes her the third-largest philanthropist of all time by total lifetime donations, according to Forbes.
Scott is a novelist and the former spouse of Amazon founder Jeff Bezos. She has distributed the funds primarily through large, unrestricted grants to non-profit organisations across the United States and internationally. Her total giving since 2019 now stands at $26 billion, according to publicly disclosed figures compiled by philanthropy trackers and financial publications.
