Lucy Guo dethrones Taylor Swift as the youngest self-made female billionaire at 30, thanks to her stake in ScaleAI. AI entrepreneur Lucy Guo has become the world’s youngest self-made female billionaire at 30, surpassing Taylor Swift. Despite being ousted from her own company, Guo’s 5% stake in ScaleAI is now valued at $25 billion which launched her net worth to $1.3 billion.
Lucy Guo, a 30 year old entrepreneur and co-founder of ScaleAI has been officially named the world’s youngest female billionaire. Guo has surpassed music industry celebrities like Taylor Swift, Rihanna, and Selena Gomez.
Forbes’ 2025 list of America’s Richest Self-Made Women has just confirmed Guo’s achievement as the youngest female billionaire with a net worth of $1.3 billion. This milestone comes after ScaleAI, the artificial intelligence data-labeling firm she helped launch at the age of 21 and which has now reached a valuation of $25 billion in a landmark deal.
Guo, who is a college dropout, grew up in the San Francisco Bay Area. She is the daughter of Chinese immigrants and she began coding in middle school and later attended Carnegie Mellon University. However, she dropped out after receiving a $100,000 Thiel Fellowship which was founded by the venture capitalist Peter Thiel to support young entrepreneurs skipping college.
Despite being ousted from ScaleAI after internal disagreements with co-founder Alexandr Wang, Guo retained her 5% stake in the company. That stake has now propelled her into billionaire territory, even though she no longer plays a role in the firm’s operations.
Guo’s journey has drawn attention for both her intense work ethic and her high-profile, fast-paced lifestyle. Her rise contrasts sharply with the entertainment-driven billionaire narratives. Until now the popular American singer, Taylor Swift, who crossed the billionaire threshold in 2023 at the age of 33 had held the title of youngest self-made female billionaire.
Guo’s story underscores a growing trend of tech founders disrupting traditional paths to wealth. From coding in middle school to building a billion-dollar fortune by 30, Lucy Guo’s ascent signals the increasing dominance of AI in shaping tomorrow’s billionaire class.
