Larry Ellison, Oracle co-founder, has surpassed Elon Musk as the world's richest person, with a net worth of $393 billion. Oracle's stock soared over 40% following a strong earnings report showcasing significant growth in its cloud infrastructure and AI businesses. Musk's Tesla shares have fallen this year, contributing to the shift. Ellison's wealth is largely tied to Oracle's success, while Musk's potential future earnings are contingent on meeting ambitious Tesla targets.
