Moritz is a signatory of
The Giving Pledge, committing himself to give away at least 50% of his wealth to charitable causes. In June 2008, Moritz and his wife announced a donation of US$50 million to Christ Church, his Oxford college, the largest single donation in the college's history. In July 2012, it was announced that Moritz had donated £75m to
Oxford University to provide £11,000 scholarships to students from families with an annual income below £16,000. The donation is the largest financial donation to an undergraduate university in European history. In February 2013, he gave $5 million for
Juilliard School's Music Advancement Program. In September 2013, he and his wife gave $30 million to the
University of California, San Francisco (UCSF) to create the UCSF Discovery Fellows Program, the largest endowed programme for PhD students in the history of the
University of California; UCSF will raise $30 million in matching funds. In February 2016, he and his wife gave $50 million to the
University of Chicago (UC), benefiting the Odyssey programme, which supports lower-income students with outstanding potential; UC will raise $50 million in matching funds. In October 2016,
The Guardian reported that Michael Moritz "donated $49,999 to a divisive ballot measure intended to clear San Francisco's streets of homeless encampments, according to campaign filings". Moritz later wrote an
op-ed for the
Wall Street Journal opposing a homelessness funding measure. In May 2018, Moritz donated $20 million to the
American Civil Liberties Union (ACLU), the largest donation the organization has received. He donated to the
Lincoln Project, a Republican-led super PAC opposing the re-election of
Donald Trump and Republican Senators who supported him.
SFGate notes that he also donated $336 million into various political and social causes in
San Francisco over three years. These causes include organizations such as SF Parent Action, which, in 2022, advocated for a recall of members of the city's school board, and also TogetherSF Action, which is known for ads critical of San Francisco's drug policies that appeared all over the city in May 2023. In 2024 Moritz and TogetherSF backed the mayoral campaign of
Mark Farrell.
Crankstart In 2019, it was announced that his and his wife's charity Crankstart would be sponsoring the
Booker Prize for novelists for the next five years. The couple did not want the name of their charity to be attached to the prize, which subsequently reverted to its old name of the Booker Prize. In September 2025, it was announced that Crankstart would give £150 million to the
National Gallery London for a new extension, with a further £150 million coming from the
Julia Rausing Trust. ==Books==
