Zuckerberg Commits $1-Billion More to Silicon Valley Community Fund

Mark Zuckerberg, Facebook co-founder, plans to give 18 million shares of his company’s stock, currently worth nearly $1-billion, to the Silicon Valley Community Foundation, according to Emmett Carson, the fund’s chief executive.

The gift comes a year after Mr. Zuckerberg and his wife, Priscilla Chan, donated shares then worth $500-million to the community fund. In recent months, the value has grown tremendously, to at least $986 million. Mr. Carson declined to say how the money would be used, but when the couple committed money last year, they said they wanted it to go primarily to health and education.

Mr. Carson called the Zuckerberg commitment “a historic, tremendous gift.” He added: “We think that is a real statement that others will get in terms of examining how they can help others do charitable work.”

The commitment from Mr. Zuckerberg marks a milestone: It is one of the biggest gifts ever made by someone under age 30 and is the largest contribution of cash or stock made by any donor so far this year. Already the couple is among America’s most generous donors, ranking No. 2 on The Chronicle’s most recent list of the 50 most-generous donors.
