Lucy Guo Becomes World’s Youngest Self-Made Female Billionaire, dethroning Taylor Swift

In a stunning move, Lucy Guo has become the world’s youngest self-made female billionaire, surpassing pop sensation Taylor Swift according to Forbes. Guo’s estimated net worth of $1.3 billion comes from her stake in Scale AI, the data-labeling firm she co-founded at age 21 alongside Alexandr Wang in 2016. Guo recently stepped back from Scale AI in 2018 but retains a 5% stake valued at roughly $1.2 billion.
