Mark Zuckerberg is one of the most prominent men in the world — and, for better or worse, an immensely influential figure in how we communicate and connect with one another. He co-founded Facebook when he was just 19 years old, turning social networking from a niche internet activity into a defining aspect of everyday life. Two decades on, he remains at the center of the company he built, now known as Meta, which continues to corner the market with apps like Facebook, Instagram and WhatsApp, attracting more than 3 billion users a day.
Who Is Mark Zuckerberg?
Mark Zuckerberg is the co-founder and CEO of Meta, the parent company of sites including Facebook, Instagram and WhatsApp. Zuckerberg launched Facebook while attending Harvard University in 2004 and helped transform it into one of the world’s largest social media companies. He currently oversees Meta’s AI strategy, while continuing to shape its broader strategy and direction.
But Zuckerberg has never been one to simply rest on his laurels. Over the years, he has repeatedly tried to steer his company toward the next major technological shift, whether that be social media, the metaverse or, more recently, artificial intelligence. Some of those bets have worked better than others, but considered together they show how Zuckerberg thinks about the future, and how he uses Meta to pursue those opportunities.
Mark Zuckerberg’s Early Life
Mark Zuckerberg was born on May 14, 1984 and grew up in Dobbs Ferry, New York, a suburb of New York City. He developed an interest in computers at an early age, taking programming lessons from a private tutor who reportedly described him as a “prodigy” when he was just 11 years old.
Zuckerberg’s first foray into software development was “ZuckNet,” a messaging program he built for his father’s dental practice to share patient information more discreetly. By the time he was in high school, he had already created multiple platforms, including a music recommendation tool called Synapse that could track users’ listening habits, analyze their preferences using machine learning and generate personalized playlists. Synapse attracted acquisition offers from Microsoft and AOL, but Zuckerberg turned them both down to attend Harvard University in 2002, where he would go on to create Facebook.
Founding Facebook
While studying computer science and psychology at Harvard, Zuckerberg dabbled in various projects on his own. One of the most notable was Facemash, a site that allowed students to compare photos of classmates and vote on who was more attractive. But that was shut down within days after it overwhelmed Harvard’s network and drew criticism for using people’s photos without permission.
Then, in February 2004, Zuckerberg launched Facebook with classmates Eduardo Saverin, Dustin Moskovitz, Chris Hughes and Andrew McCollum. Originally called “TheFacebook,” the site was designed as an online directory where Harvard students could create profiles and connect with each other. It quickly expanded to other universities and was made available to high school students shortly thereafter. Eventually, anyone over the age of 13 with an email address could have a Facebook account.
After dropping out of Harvard during his sophomore year, Zuckerberg moved Facebook’s operations to Palo Alto, California, where it quickly secured millions in venture funding and grew into one of the world’s largest social media platforms, attracting more than a billion users. Some of the company’s earliest backers include prominent figures like Peter Thiel, who co-founded PayPal and Palantir, LinkedIn co-founder Reid Hoffman and Napster co-founder Sean Parker, who served as Facebook’s first president for about a year.
The company experienced some legal challenges early on, though. Shortly after Facebook’s launch, Harvard classmates Cameron Winklevoss, Tyler Winklevoss and Divya Narendra accused Zuckerberg of stealing ideas and source code intended for their own social networking project, HarvardConnection. The conflict ended in a 2008 settlement that included cash and Facebook stock, but the Winklevoss twins later sought additional compensation (and lost). Zuckerberg was also embroiled in a dispute with Eduardo Saverin after the company diluted Saverin’s ownership stake during an early funding round. In the end, the two reached a confidential settlement out of court in 2009, and Saverin retained the title of co-founder.
Facebook ultimately went public in 2012 in one of the biggest technology IPOs in history. It later expanded through several major acquisitions, including Instagram, WhatsApp and Oculus VR, a virtual reality startup founded by Palmer Luckey, who is now the head of defense tech pioneer Anduril Industries. The Oculus acquisition in particular helped lay the groundwork for Meta’s virtual and augmented reality push in 2021, which is currently housed under its Reality Labs division, and contributed to the foundation of what is now Meta.
Facebook’s Metaverse to Meta AI Pivot
In 2021, Zuckerberg announced one of the biggest strategic shifts in Facebook’s history, changing the name of its parent company to Meta to reflect his vision for the “metaverse” — a network of immersive digital worlds where people can work, socialize, shop, exercise and play using virtual and augmented reality. Convinced the metaverse would become the next big thing after smartphones, Meta poured tens of billions of dollars into the effort through its Reality Labs division, developing products like VR headsets and smart glasses.
Despite all of this effort, the metaverse failed to gain mainstream traction. Meta continued to generate billions of dollars in advertising revenue from apps like Facebook and Instagram, but Reality Labs hemorrhaged money. The company has since drastically scaled back its Reality Labs team, closing multiple VR game studios and shutting down the VR version of its Horizon Worlds social network.
The breakout success of ChatGPT in 2022 marked another turning point for Meta. Although the company had been developing its own internal AI and machine learning models through its Fundamental AI Research (FAIR) lab for a decade, the rapid adoption of generative AI prompted Zuckerberg to make artificial intelligence a bigger priority.
Meta adopted an open strategy initially, releasing its Llama family of large language models that users could freely download, customize and build upon. But the company has since shifted its primary focus to developing closed, proprietary models through Meta Superintelligence Labs, a division that houses all its AI teams and initiatives. Created after Meta acquired AI infrastructure startup Scale AI for $15 billion, MSL’s ultimate goal is to create what Zuckerberg calls “personal superintelligence,” where advanced AI systems are built for individual use and fulfillment rather than just enterprise or research applications.
Although Meta continues to develop AR and VR products, as well as operate its assortment of social media sites, artificial intelligence is now the company’s main concern. It has woven AI throughout Facebook, Instagram, WhatsApp and Messenger via its Meta AI assistant, as well as committed hundreds of billions of dollars to data centers, chips and other AI infrastructure. It has also positioned the technology as a cornerstone of its future products, user experiences and advertising business.
Meta Today
These days, Meta is as much an artificial intelligence company as it is a social media company. It has built AI into just about every part of its business, from algorithms that recommend content on Instagram to the tools advertisers use to create targeted ads on Facebook. Meanwhile, Meta AI is being integrated across the company’s entire portfolio of consumer-facing products, and its Meta Superintelligence Labs has released several new models, agentic coding tools and a personal AI agent called Muse that can perform actions across apps and services on a user's behalf.
Behind all of these products is an enormous investment in computing infrastructure. Meta spent $72 billion on capital expenditures in 2025 and expects to spend anywhere from $130 billion to $145 billion in 2026, much of which is going toward constructing new data centers to train and run ever more powerful AI models. The company is making its own AI chips as well, including the Meta Training and Inference Accelerator to supplement hardware from third-party suppliers.
Meta’s AI ambitions extend far beyond just chatbots and data centers. It is also building smart glasses equipped with cameras, microphones and speakers, giving users a hands-free way to take photos, make calls, navigate and more. These are part of a much broader push to develop AI-first devices that could eventually oust the smartphone as our primary device — but they aren’t without controversy. The specs have developed a reputation as “pervert glasses” in some circles due to incidents involving the nonconsensual recording of women and children. Plus, a recent investigation found that footage captured by Meta glasses is sometimes sent to remote contractors for review and labeling, including sensitive footage of people using the bathroom, undressing and handling bank cards.
For what it’s worth, Meta has taken steps to prevent its eyewear from being used to secretly record people anymore, but the bad press has been hard to come back from. Norway is considering an outright ban on camera-enabled wearables in public spaces, citing concerns over people’s privacy. Meta is also facing a proposed class-action lawsuit in the U.S. alleging that the company falsely marketed its glasses as “designed for privacy” while sending footage captured by the devices to foreign contractors.
Meta’s core social media business is also facing mounting scrutiny over its impact on young users specifically. In August 2026, the company agreed to pay up to $17 billion to settle a lawsuit brought by 47 states and Washington, D.C., which alleged that Facebook and Instagram were designed to hook children and teens, harming their mental health as a result. The deal also stipulates that Meta implement new child-safety measures, including stronger age verification, parental controls and usage limits for minors.
The settlement brought an abrupt end to a trial in Oakland, California after just four days of testimony, with former Meta safety engineer and whistleblower Arturo Béjar among those who took the stand. Béjar placed the blame for Facebook’s lax approach to child safety squarely on Zuckerberg, claiming “it was the company culture Mark had created that made it so that it was practically impossible to deliver features that address the wellbeing and safety issues that we’ve all been talking about.” Zuckerberg — who testified in a separate suit over similar allegations in February — did not appear in the Oakland case before Meta reached its settlement.
Mark Zuckerberg’s Net Worth and Philanthropy
Zuckerberg was declared the world’s youngest self-made billionaire in 2008 at just 23 years old, with an estimated net worth of about $1.5 billion. Today, he is worth about $222 billion, according to Forbes, making him one of the five richest people in the world. Similar to many tech billionaires, though, Zuckerberg collects a symbolic base salary of just $1 as Meta’s CEO. Instead, the vast majority of his wealth comes from his roughly 13 percent ownership stake in Meta, meaning his income rises and falls with the company’s stock price, as well as through periodic dividend payouts.
Zuckerberg and his wife, Priscilla Chan, also manage a massive philanthropic entity they founded in 2015 called the Chan Zuckerberg Initiative. While not a direct mechanism for personal monetary gain per se, CZI functions as a for-profit LLC used to deploy billions of dollars into scientific research. The company historically focused on a wide range of social and political causes, including affordable housing and education. However, it has since pivoted to become almost entirely science-focused, investing heavily in areas like artificial intelligence and biomedical research.
Overall, both Zuckerberg and Chan have pledged to donate 99 percent of their Meta shares to charity over the course of their lifetimes.
What Is Mark Zuckerberg Working on Now?
At this point, Zuckerberg’s focus is overwhelmingly on integrating AI across all of Meta’s products and developing “personal superintelligence.” To support these ambitions, his company Meta is shelling out billions of dollars to grow its AI infrastructure and poach top talent from rival labs like OpenAI and Apple. In fact, Zuckerberg has personally led many of these recruiting efforts, viewing the race to build advanced AI systems as one of the most consequential competitions of the century.
Zuckerberg is also quite politically active, dining with President Donald Trump on multiple occasions and attending his 2025 inauguration. What’s more, Zuckerberg is probably one of the tech industry’s most influential voices in AI policy at the moment, warning that overly restrictive regulations could slow innovation and weaken the United States’ ability to compete with China. He even has sway behind the scenes, according to reports — most recently expressing concerns during a private call with Trump about a proposed national AI oversight body that would review advanced AI models before they are deployed. Meta has bolstered its CEO’s agenda with an increasingly assertive political strategy of its own, launching two super PACS to boost pro-AI candidates running on the state level and fight off what it sees as onerous AI policy bills across the country.
At the same time, Zuckerberg seems interested in taking Meta beyond just social media and AI. The company is rumored to be working on a prediction market app called “Arena” that could compete with wildly popular platforms like Polymarket and Kalshi, allowing users to bet on future events and, eventually, share their predictions across Instagram and Facebook. Sources familiar with the project told The New York Times that Arena is being tested internally, though it may never launch publicly. Still, the idea fits Zuckerberg’s usual playbook: spot the next big trend early and position Meta to capitalize on it.
