Kalshi co-founder Luana Lopes Lara becomes the youngest self-made female billionaire in history, surpassing Taylor Swift and Lucy Guo.

Lopes Lara has just become the youngest self-made woman billionaire on Earth, unseating 31-year-old Scale AI cofounder Lucy Guo who took the title from Taylor Swift in April. She and her cofounder, Tarek Mansour, also 29, both moved into the three comma club after their prediction market firm raised $1 billion at an $11 billion valuation. Crypto-focused venture capital firm Paradigm led the round, announced Tuesday, which also included investors Sequoia Capital, Andreessen Horowitz and Y Combinator among others.

Almost 8 years ago the founders of Kalshi made what so many told them was the dumbest decision of their lives.

Today that stupid decision is worth $11b. Kalshi lore is worth studying for early founders. I wanted to join the team because of it.
