Tycoon Elon Musk is no longer the richest person in the world, a title he has managed to hold for nearly a year. It was Larry Ellison, co-founder of the software company Oracle, who, after his company's shares soared 42% on the stock market on Wednesday, has snatched Musk's throne. The 81-year-old Oracle chairman had held second place since Tuesday, when he surpassed Mark Zuckerberg (Meta) in the ranking.
