Larry Ellison, co-founder and chairman of Oracle, has regained his position as the world's second-richest person with an estimated net worth of USD 264.8 billion, following a significant increase in Oracle's stock price. The company's shares rose 2% to around USD 212, contributing to a USD 5.2 billion increase in Ellison's wealth. This surge pushed him past Google co-founders Larry Page and Sergey Brin, whose net worths are estimated at USD 259.7 billion and USD 239.6 billion, respectively. Elon Musk remains the world's richest individual with a net worth of approximately USD 493.6 billion. In India, Mukesh Ambani and Gautam Adani also saw increases in their wealth, ranking 18th and 20th globally with net worths of USD 106 billion and USD 84.2 billion. The shift in billionaire rankings reflects Oracle's strong performance and Ellison's strategic investments, including a billion-pound research institute in Oxford and significant involvement in yachting and technology sectors.
