Mark Zuckerberg, the iconic founder of Facebook, is one of the most recognisable figures in the tech world. Known as a pioneer in social networking and a staunch advocate of philanthropy, Zuckerberg’s net worth stands at a staggering $232 billion. Despite the ups and downs of tech stocks and global scrutiny of his platform, he remains one of the richest individuals on the planet—and by far, the youngest among the top 100.
In this in-depth profile, we explore how Zuckerberg built his empire, what contributes to his massive fortune, and what he plans to do with it.
Early Life and Background
A Prodigy from a Young Age
Mark Elliot Zuckerberg was born on 14 May 1984 in White Plains, New York. Raised in nearby Dobbs Ferry, he grew up in a well-educated family. His father, Edward Zuckerberg, is a dentist, while his mother, Karen, worked as a psychiatrist. Mark has three sisters—Randi, Donna, and Arielle—with whom he shared a home environment that encouraged creativity and intellectual pursuits.
Zuckerberg began programming in middle school, learning BASIC from his father and later receiving private tutoring from software developer David Newman. One of his earliest projects was ZuckNet, a messaging system that linked his house and father’s dental office computers—essentially a precursor to instant messaging.
Academic Excellence
Mark attended Ardsley High School before transferring to Phillips Exeter Academy, where he shone academically and captained the fencing team. Notably, he also created an intelligent music software called Synapse Media Player, which caught the attention of both Microsoft and AOL—offers he ultimately turned down.
Harvard and the Birth of Facebook
Humble Beginnings in a Dorm Room
Zuckerberg entered Harvard University in 2002, studying psychology and computer science. It wasn’t long before he started attracting attention for his programming talents. Projects like CourseMatch and the controversial Facemash—which let students rank others based on attractiveness—laid the groundwork for something bigger.
On 4 February 2004, Zuckerberg launched Thefacebook.com, a social platform built from his dorm room alongside co-founders Dustin Moskovitz, Chris Hughes, and Eduardo Saverin. Initially exclusive to Harvard students, the site expanded rapidly to other universities and beyond.
Dropping Out and Going All In
By mid-2004, Zuckerberg and his team relocated to Palo Alto, California, where Facebook would truly begin to scale. Backed by early investors like Peter Thiel, the platform started gaining traction at an exponential rate. Zuckerberg made the bold move to drop out of Harvard during his sophomore year to fully commit to the venture.
Building the Facebook Empire
Growth and Global Reach
From its modest start, Facebook blossomed into a global social network boasting billions of users. By July 2010, Facebook had already surpassed 500 million users. Its meteoric rise caught the attention of major tech companies, many of whom attempted to acquire it—but Zuckerberg wasn’t selling.
Facebook IPO and Zuckerberg’s Wealth
On 18 May 2012, Facebook went public at $38 per share. At the time, Zuckerberg owned 400 million shares, making his stake worth an estimated $15 billion on the day of the IPO.
Wealth Timeline: Key Milestones
From Billionaire to Multi-Billionaire
- 2007: Becomes a billionaire on paper when Facebook raises $240 million from Microsoft at a $15 billion valuation.
- 2012: Facebook IPO cements his wealth at $15 billion.
- August 2020: Net worth crosses $100 billion for the first time.
- Late 2021: Wealth peaks at $137 billion, making him the third-richest person in the world.
A Temporary Setback
In 2022, Zuckerberg’s net worth took a massive hit due to a 70% drop in Meta (formerly Facebook) shares. From $126 billion in January, it plummeted to $37 billion by October—losing $89 billion in less than a year. This made him the biggest financial loser of the year among billionaires.
Resurgence in 2023 and Beyond
Fortunately for Zuckerberg, the drop was short-lived. In 2023 and early 2024, Meta’s stock rebounded. On 2 February 2024, with Meta shares at an all-time high, Zuckerberg’s net worth soared to $170 billion, marking his richest point to date. By mid-2025, his fortune stood at approximately $232 billion.
Zuckerberg’s Facebook Holdings
A Breakdown of His Shares
Mark Zuckerberg owns roughly 400 million shares of Facebook/Meta, categorised into:
- 12 million Class A shares
- 365 million Class B shares
Class B shares come with super-voting rights, giving Zuckerberg 53% control over company decisions. Additionally, he controls co-founder Dustin Moskovitz’s Class B shares, giving him an effective 58% voting power in the company.
Salary and Compensation
Zuckerberg famously draws a symbolic salary of $1 per year. This practice is not uncommon among tech executives who prefer to grow their wealth via stock appreciation rather than annual income. Other executives, including Larry Page and Elon Musk, have employed similar strategies.
Philanthropy and the Chan Zuckerberg Initiative
Giving Away 99% of His Wealth
Mark Zuckerberg has pledged to donate 99% of his Facebook shares during his lifetime. Along with his wife, Priscilla Chan, he established the Chan Zuckerberg Initiative (CZI) in 2015 with a mission to “advance human potential and promote equality.”
Major Contributions
- In 2018, Zuckerberg sold $5.3 billion worth of Facebook shares for charitable use.
- In 2019, he sold an additional $1.86 billion.
- CZI focuses on education, health, science, and justice reform.
Zuckerberg and Chan are also signatories of The Giving Pledge, initiated by Bill Gates and Warren Buffett.
Legal Challenges and Controversies
The ConnectU Lawsuit
In the early days of Facebook, Zuckerberg faced a major legal battle. Harvard students Divya Narendra and Cameron and Tyler Winklevoss sued him, claiming he stole their idea (HarvardConnection, later renamed ConnectU).
The case was settled in 2008, with the plaintiffs receiving 1.2 million Facebook shares and $20 million in cash. Those shares are now worth over $200 million.
Cambridge Analytica Scandal
In April 2018, Zuckerberg testified before the U.S. Senate in relation to the Facebook–Cambridge Analytica data breach. The controversy involved the unauthorised use of Facebook user data for political profiling—one of the biggest privacy breaches in tech history.
Personal Life
Marriage and Family
Zuckerberg met Priscilla Chan at Harvard in 2003. The couple married on 19 May 2012, the day after Facebook’s IPO. They have three daughters: Maxima (born 2015), August (born 2017), and Aurelia (born 2023).
Hobbies and Interests
Zuckerberg is multilingual, listing French, Hebrew, Latin, and ancient Greek among the languages he could read and write on his college application.
In 2022, he took up Brazilian Jiu-Jitsu (BJJ) and Mixed Martial Arts (MMA). In 2023, he won gold and silver medals at a local BJJ competition. He is also reportedly training to obtain a pilot’s licence.

Palo Alto Compound
