Larry Ellison, co-founder and chief technology officer of Oracle, has become the world's second-wealthiest person for the first time, surpassing Meta CEO Mark Zuckerberg. According to the Bloomberg Billionaires Index, Ellison's net worth has risen to approximately $257 billion, driven by a sharp rally in Oracle's share price, which has surged about 90% in the last three months. This increase is largely attributed to Oracle's strategic investments and advancements in artificial intelligence, including partnerships with OpenAI and contracts with the U.S. government. Ellison retains a 41% stake in Oracle, which has contributed significantly to his wealth growth, with gains exceeding $60 billion in 2025 alone. At 80 years old, Ellison's rise to the second spot on the global rich list reflects the growing market value of technology companies focused on AI. His financial ascent has also been accompanied by public support for fellow tech entrepreneur Elon Musk.
