Spurred on by the artificial intelligence (AI) craze, Oracle's stock price witnessed a remarkable surge in September, briefly catapulting its founder, Larry Ellison, to the pinnacle of global wealth. However, the subsequent downward trajectory of the stock price has led to a staggering $130 billion reduction in Ellison's personal net worth. This downturn in Oracle's stock performance has enabled Larry Page to overtake Ellison for the first time in the Bloomberg Billionaires Index, propelling Page to the second - spot, while Ellison has slid down to the third position.

Previously, Oracle's AI - related cloud infrastructure business was the driving force behind a 36% single - day spike in its stock price. But this gain was completely wiped out in a mere two months. Moreover, Oracle's AI strategy leans heavily on OpenAI, and there are growing concerns in the market regarding its increasing reliance on debt financing.

In stark contrast, Alphabet's stock price has soared by 58% this year, largely attributable to the positive reception of its Gemini AI model. As of 2025, Page's personal net worth has ballooned by $88.6 billion. Additionally, Sergey Brin is set to make a comeback to the company. He currently holds the fifth position on the Bloomberg Billionaires List, with a net worth of $239.9 billion.
