- In 2025, the Chronicle of Philanthropy recorded media entrepreneur and former New York mayor Michael Bloomberg leading the Philanthropy 50 list as the 50 biggest U.S. donors gave $22.4 billion to charity.
- The Chronicle found technology donors supplied $10 billion and financial-industry philanthropists gave $4.1 billion, with the median gift at $105 million and many maintaining long-term donor–charity relationships.
- Supporting gifts included Bloomberg gave $4.1 billion to causes like arts, education, and public health, followed by three other donors each giving $1 billion or more last year.
- Health and research organizations received $1.5 billion, science and technology got more than $3 billion, and athletics received $871 million, with New York and California states receiving the most gifts.
- Observers note that a small number of donors dominated giving this year, with Mike Bloomberg accounting for 19% and the top 10 donors supplying nearly three-quarters, while MacKenzie Scott did not appear, likely due to donor-advised funds or limited disclosure.
