Bloomberg Philanthropies

Bloomberg Philanthropies was established in 2006 by Michael R. Bloomberg as the umbrella for his charitable activities. The Bloomberg Family Foundation serves as the primary 501(c)(3) vehicle. Wealth originated from Bloomberg L.P., where Bloomberg retains an 88 percent stake. The foundation allocates across arts, education, environment, government innovation, and public health. Asset allocation data shows 90 percent in private equity. Confirmed holdings include positions in Circle and multiple biotechnology companies held through Willett Advisors. Geographic reach covers North America, Europe, and Latin America through city advisory work and global forums. The organization employs 435 professionals. Bloomberg Associates, founded in 2014, provides pro bono consulting to city governments. A September 2025 Global Forum in New York addressed climate and public health topics. Additional offices are not disclosed. Bloomberg Philanthropies maintains separation between grant-making and investment management via Willett Advisors. Michael Bloomberg's role as founder and primary donor creates a direct link between personal wealth and program priorities without external limited partners.
