Lucy Guo has an estimated net worth of $1.5 billion, according to Forbes Real-Time Billionaires, Lucy Guo profile (figures as of October 20, 2026). That is up from $1.4 billion in 2026.
Lucy Guo is an American entrepreneur and engineer known for cofounding Scale AI and later starting Passes. She taught herself to code in elementary school after getting interested in Neopets. Guo studied computer science and human-computer interactions at Carnegie Mellon University, then left before graduating after becoming a Thiel Fellow in 2014. Early in her career, she interned at Facebook, joined Snapchat as its first female designer, and later worked at Quora.
Her biggest business break came in 2016, when she and Alexandr Wang started Scale AI. She left the company in 2018, but kept an ownership stake that became the main source of her wealth. In 2022, she founded Passes, a platform where creators and celebrities connect with fans, and became its CEO. Forbes says she was the world's youngest self-made woman billionaire from April 2025 to December 2025.
How Lucy Guo makes money
Most of Guo's fortune comes from her remaining stake in Scale AI. She launched the company in 2016 and left in 2018, but Forbes says she still owns roughly 3% of the business. Scale AI works in artificial intelligence through data labeling, and that stake is the biggest reason her wealth rose into billionaire territory. Her money story is tied much more to equity ownership than to a salary or a one-time payout.
Guo also runs Passes, which she founded in 2022. The platform connects creators and celebrities with fans and has been compared with Patreon and OnlyFans. She serves as CEO and has raised $50 million from investors. Earlier in her career, she also launched Apply to Date in 2018 and started Backend Capital in 2019, a firm focused on early-stage engineering startups. Those projects added to her profile as a repeat founder.
What moved her Forbes fortune
A major turning point came in June 2025, when Meta bought 49% of Scale AI for about $14 billion and Scale paid shareholders a hefty dividend. That deal lifted the value of Guo's remaining ownership and helped push her into a new tier of wealth. Forbes later ranked her as the world's youngest self-made woman billionaire from April 2025 to December 2025, a title tied to the jump in Scale AI's value.
On Forbes' World's Billionaires List 2026, Guo was estimated at $1.4 billion. Forbes' real-time billionaires tracker later put her at $1.5 billion as of October 20, 2026. Both figures point back to the same core asset: her stake in Scale AI. Passes matters to her business career, but the Forbes estimate is driven mostly by what she still owns in the artificial intelligence company she helped build.
