Lucy Guo Becomes Youngest Self-Made Female Billionaire

Lucy Guo, a 30-year-old first-generation Chinese-American and co-founder of Scale AI, has become the world's youngest self-made female billionaire after a major tender offer valued Scale AI at $25 billion, making her estimated 5% stake worth about $1.2 billion. Guo, who left Scale AI in 2018 following a disagreement, has since launched other ventures including the creator platform Passes. She is now one of only six self-made women billionaires under 40 and the only one to have built her wealth from a company she no longer manages. Forbes reports she has surpassed Taylor Swift, 35, who remains the wealthiest female musician with a net worth of $1.6 billion from her Eras Tour and music catalog. Passes, Guo's company, faces a lawsuit alleging inadequate safety controls around explicit content, which Guo denies. Guo's ascent highlights both the power of Silicon Valley networks and ongoing debates about what defines 'self-made' success.
