Alexandr Wang net worth: how the Scale AI founder became Meta’s $3.2 billion AI chief

Alexandr Wang’s net worth was $3.2 billion, about ₹30,500 crore, on 4 November 2026, according to Forbes. The 29-year-old co-founded Scale AI, became the world’s youngest self-made billionaire at 24 and, since Meta bought 49% of Scale in 2025, has been Meta’s chief AI officer. Here is how the money was made and where it sits. 1

From Los Alamos to Scale AI

Wang was born in January 1997 and grew up in Los Alamos, New Mexico, where his parents worked as physicists, according to Wikipedia. He worked as a software engineer at Quora, enrolled at the Massachusetts Institute of Technology, and in 2016, at 19, left to co-found Scale AI through the Y Combinator accelerator. 2

Scale labels and prepares the data that AI models learn from, for AI labs, carmakers and the US government. That made it one of the picks-and-shovels businesses of the AI boom.

Alexandr Wang net worth: how it grew

In 2021 Scale was valued at $7.3 billion, and Wang’s stake of about 15% made him a billionaire at 24, the youngest self-made one in the world at the time, Wikipedia says. Forbes estimated his fortune at $3.6 billion in April 2025. 2

In June 2025 Meta invested $14.3 billion for 49% of Scale, valuing it at about $29 billion. Wang stepped down as Scale’s chief executive, stayed on its board and joined Meta as chief AI officer, where he leads Meta Superintelligence Labs for Mark Zuckerberg. Forbes still counts his remaining Scale stake. 12

His fortune has slipped since then, to $3.2 billion by November 2026, according to Forbes. Because Scale is private, the figure moves with its private valuation rather than a share price. The full breakdown is on our Alexandr Wang net worth page, and our explainer on Forbes vs Bloomberg net worth shows why estimates differ. 1

Is he still the youngest self-made billionaire?

No. Forbes says he held the title until October 2025, when Polymarket founder Shayne Coplan overtook him. 1

What he does at Meta

As chief AI officer, Wang runs the company’s push toward more capable AI models and products, one of the biggest bets in Big Tech. That makes him one of the most closely watched executives in artificial intelligence, alongside founders such as Sam Altman, whose wealth also comes from outside his main company, as we explained in Sam Altman’s net worth.

What happens next

Any new funding round or sale involving Scale would reset its valuation and move Wang’s net worth with it. For his life story, family and companies, see the Alexandr Wang profile.
