Elon Musk has been dethroned as the world’s richest person by Oracle co-founder Larry Ellison after over 300 days at the top. Musk’s $385 billion net worth trails Ellison’s $393 billion, boosted by a record $101 billion surge in Oracle stock. At 81, Ellison now leads Bloomberg’s Billionaire Index, with most wealth tied to his 40% Oracle stake.
