Oracle's founder once became the world's richest man, with his wealth soaring by hundreds of billions in one day

The title of "world's richest man" has changed hands again, with a reshuffle in the wealth rankings among the top tycoons capturing global attention.

According to the latest data from the Bloomberg Billionaires Index, after nearly 300 days as the world's richest man, Tesla CEO Elon Musk has temporarily lost the title.

In his place is Oracle co-founder Larry Ellison. The immediate driver of this change was Oracle's astonishing stock price performance.

Driven by strong demand for its cloud business and a significant upward revision to its revenue forecast, the company's stock price surged over 42% during the session and closed up 36%, its largest single-day percentage gain since 1992. The $244 billion surge in market capitalization in a single day also made it a focal point for the market.

As of Tuesday, Musk remained at the top of the world's richest list with a net worth of $384 billion, followed closely by Ellison with $295 billion. However, after the market closed that day, Oracle released positive signals: it not only raised its sales forecast but also announced several major customer wins.

This news quickly ignited market enthusiasm, driving its stock price sharply higher.

According to newly disclosed shareholding documents, Ellison currently holds 1.16 billion shares of Oracle. Based on Wednesday's intraday high of $345.72, his personal wealth skyrocketed by nearly $120 billion in a short period of time, reaching $414.8 billion, propelling him to the top of the Billionaires Index for the first time.

Although the stock price fell slightly at the close, his net worth stabilized at $380.8 billion, still demonstrating an astonishing single-day increase in wealth.

On the other hand, Musk's wealth is primarily based on his holdings of 506.8 million Tesla shares. As of Wednesday's close, the fluctuations in Tesla's stock price had boosted the total value of his holdings to $384.6 billion, allowing him to regain his position as the world's richest person.

This "richest man race" not only saw dramatic changes within a single day, but also reflected the high volatility of the tech stock market and the close correlation between the wealth of top entrepreneurs and their company's stock price.

Analysts point out that the rapid growth of cloud computing continues to reshape the new business landscape, while traditional software giants like Oracle are once again gaining market favor thanks to their successful transformation.

Meanwhile, the electric vehicle industry, while offering high growth potential, also faces challenges from cyclical fluctuations and intensified competition. The industry dynamics behind these two entrepreneurs thus provide a window into global economic trends.
