Mark Zuckerberg

Overview

Mark Zuckerberg is an American entrepreneur and the CEO, chairman, and controlling stakeholder of Meta. As of early 2026, Zuckerberg was among the world's top six richest people, with an estimated net worth of roughly $218.9B.

In 2004, Zuckerberg created the social network Facebook in his dorm at Harvard University, dropping out of Harvard to run the company in California in 2005. Today, Facebook (now Meta) is a company valued at more than $1T that owns Instagram and WhatsApp and is heavily invested in artificial intelligence.

Zuckerberg has faced significant criticism for Facebook's role in perpetuating what some say is a toxic social media environment for children. In 2018, Zuckerberg testified before Congress over the Cambridge Analytica scandal, in which a consulting firm with Russian and conservative ties compromised the private data of more than 80 million Facebook users.

In many ways, Zuckerberg's vision for new technologies has been a defining feature of Meta's growth. Since founding the company, Zuckerberg has retained control of Meta (then Facebook) and has repeatedly said he doesn't intend to sell it.
