Detailed summary

The Meta CEO and Priscilla Chan pledged 99% of their shares in a 2015 letter to their newborn. Those shares were worth $45 billion then; his fortune now tops $200 billion.

When Mark Zuckerberg and Priscilla Chan pledged to give away 99% of their Facebook shares in 2015, the stake was worth about $45 billion. Zuckerberg’s fortune now exceeds $200 billion, and their three daughters still aren’t slated to inherit most of it.

That puts the Meta CEO and Chan, a pediatrician, in a cohort of ultra-wealthy households, including Bill Gates, Warren Buffett, and Michael Bloomberg, where the children won’t be inheriting the bulk of the balance sheet.

The couple announced the decision in December 2015, after the birth of their first child, Maxima. In an open letter to their newborn, they introduced the Chan Zuckerberg Initiative (CZI) and committed to giving away 99% of their Facebook (now Meta) shares during their lifetimes.

“Like all parents, we want you to grow up in a world better than ours today,” they wrote.
