How a Kylie Jenner Rumor Sparked a $22 Billion Prediction Market

Today, at 29, Lopes Lara stands as the world’s youngest self-made female billionaire with a net worth of $2.6 billion. Her platform, Kalshi, has seen its valuation more than double since December following a Series F funding round led by Coatue. The firm’s expansion has been aggressive, with the workforce swelling from 35 to 150 employees over the past year. Last month alone, the platform processed nearly $18 billion in trading volume, with sports-related wagers accounting for 80% of that activity.

This rapid ascent remains tethered to significant industry friction. Prediction markets face persistent scrutiny regarding insider trading, and Kalshi recently grappled with a public backlash after a market tied to Iran’s Supreme Leader triggered controversy. The firm responded by reimbursing $2.2 million in fees and losses to users caught in the fallout. While the original bet regarding Jenner never materialized, the platform now facilitates millions of similar speculative exchanges.
