India, Dec. 3 -- Luana Lopes Lara, 29, has become the world's youngest self-made woman billionaire after her prediction-market startup, Kalshi, reached a $11 billion valuation. Lara has taken the title from Scale AI's Lucy Guo, who herself only recently surpassed Taylor Swift.

According to a Forbes report, Kalshi raised $1 billion in a new round led by crypto-focused VC firm Paradigm, with participation from Sequoia Capital, Andreessen Horowitz, and Y Combinator. The fundraising pushes both cofounders, Lopes Lara and her MIT classmate Tarek Mansour, also 29, into the billionaire ranks, with each now holding an estimated net worth of $1.3 billion.
