Forbes put Alexandr Wang's net worth at $3.6 billion in April 2025. That figure predates Meta's June 2025 investment in Scale AI, so treat it as a dated snapshot rather than a current number.
Wang left MIT after about a year and founded Scale AI in 2016 with Lucy Guo, going through Y Combinator. A $100 million round led by Founders Fund in 2019 pushed the valuation past $1 billion. A July 2021 round valued the company at $7 billion, and with a stake of about 15 percent Wang became a billionaire at 24.
Scale's valuation reached almost $13 billion in March 2024 and $14 billion in May 2024. The company reported revenue of $870 million in 2024.
In June 2025 Meta agreed to take 49 percent of Scale AI for roughly $14.3 billion, which implied a valuation of about $29 billion. Wang stepped down as CEO, Jason Droege took over, and Wang became Meta's Chief AI Officer.
