Larry Ellison lost an estimated $25 billion in a single day after Oracle shares plunged more than 11% on weaker-than-expected earnings, according to Bloomberg’s Billionaires Index. The drop cut Ellison’s net worth to $258 billion, marking one of the steepest single-day wealth declines of 2025.
Oracle missed Wall Street revenue expectations despite posting 14% year-over-year growth, fueling concerns about the company’s massive spending on artificial intelligence infrastructure.

Co-CEO Clay Magouyrk rejected those concerns, saying the company expects to require “substantially less” funding and emphasized Oracle’s debt remains investment-grade.
