The Chan Zuckerberg Foundation is the formally charitable arm of the Chan Zuckerberg Initiative, the nonprofit foundation of Facebook billionaire Mark Zuckerberg and his wife Priscilla Chan. The Advocacy has a political sister group, Chan Zuckerberg Advocacy. All three groups receive 100% of their funding from Facebook shares donated by Zuckerberg and Chan.

The Foundation primarily donates to scientific research, universities, and education initiatives, though it has also contributed to left-of-center advocacy groups involved in education, immigration, low-income housing, and criminal justice policy. The Foundation is also a signer Bill Gates’ “Giving Pledge,” in which Gates invited billionaires “to commit to give the majority of their wealth to philanthropy either during their lifetimes or in their wills.” 1 2

As of 2018, the Foundation had no listed employees or executives other than Mark Zuckerberg as trustee.


Since 2018, the Chan Zuckerberg Foundation has given 68 grants ranging from $50,000 to over $60 million. 3

The Foundation’s largest grant of just over $60 million is going to Gates Philanthropy Partners over a four-year period from 2018-2022. The grant contributes to a portfolio to develop treatments for heart disease and stroke in low and middle-income countries. 4

The Foundation’s second largest recipient is NewSchools Venture Fund, which over two grants stretching from 2018-2022 is receiving $45 million. The Fund works to improve education outcomes for low-income Americans, particularly in math. 5

The Foundation has given considerable funds in support of charter schools. Summit Public Schools, a network of eleven charter schools in California and Washington, received almost $29 million from 2018-2019. T.L.P Education, which runs the Summit Public Schools network, received $40 million from 2018-2020. 6

In 2018, grants from the Foundation launched Opportunity Insights, a research and policy think tank based out of Harvard University focused on improving economic opportunities for low-income Americans. From 2018-2021, Opportunity Insights will receive $15 million.

The Foundation has given grants to numerous universities for scientific research, primarily related to cellular biology, including $9.7 million to Harvard University, $8.6 million to University of California schools, $4 million to Northwestern University, $3.7 million to the University of Michigan, $2.5 million to the University of Washington, $2.4 million to the University of Pennsylvania, almost $2 million to the Baylor College of Medicine, almost $1.7 million to the University of Oxford, $1.5 million to Columbia University, almost $1.5 million to the University of Chicago, almost $1 million to Stanford University, $749,676 to Indiana University, $400,000 to Duke University, almost $400,000 to Ben Gurion University, and almost $400,000 to Northeastern University. 7

The Foundation has given grants to left-of-center nonprofit advocacy groups. From 2018-2023, the Foundation is giving over $39 million to the Local Initiatives Support Corporation to seed the Regional Housing Flexible Fund, a fund to provide housing to low-income individuals and racial minorities in the San Francisco Bay Area. 8

From 2018-2020, the Foundation gave $1 million to CASA de Maryland, a group which finds employment for immigrants regardless of legal status. In 2019, the Foundation gave $100,000 to the North Bay Organizing Project, a group which provides relief services to illegal immigrants impacted by California wildfires. 9

From 2018-2019, the Foundation gave $1 million to the BronxConnect program of the Urban Youth Alliance International, a criminal justice group. BronxConnect is co-sponsored by the Rockefeller Foundation. From 2019-2021, the Foundation is giving $1.1 million to the Greater Kanawha Foundation, a group of criminal justice nonprofits in West Virginia. 10
