Michael Bloomberg has taken the top spot on the Chronicle of Philanthropy’s exclusive ranking of the 50 biggest donors of 2025 for the third consecutive year.
The founder of the Bloomberg financial-news empire and former New York mayor gave $4.3 billion in 2025 to support arts, education, the environment, public health, and programs to improve city governments. He is followed on the Philanthropy 50 list by three donors who each gave $1 billion or more to charity last year.
