In November 2025, the global wealth leaderboard saw some remarkable shifts among the world’s billionaires. The ranking showcases figures such as Elon Musk and Bernard Arnault, reflecting dramatic movements in technology and luxury markets.
Elon Musk briefly became the first individual ever valued at $500 billion twice in October. By November 1, his net worth adjusted slightly to $497 billion, marking an increase of $6 billion since the start of October. Despite a small decrease from his record, Musk widened the gap over runner-up Larry Ellison by $28 billion.
“Elon Musk’s fortune reached $497 billion as of November 1, 2025.”
Tesla’s stock climbed 3% during October, supporting this growth and maintaining Musk’s position as the world’s richest person.
Oracle cofounder Larry Ellison, now valued at about $320 billion, faced a 7% drop in Oracle’s shares, reducing his wealth by roughly $22 billion. The downturn followed an earlier high point in mid-September when Ellison briefly joined Musk in the ultra-exclusive $400 billion club due to optimism around Oracle’s cloud infrastructure business powering AI systems.
“In mid-September, Ellison’s fortune exceeded $400 billion for a short time.”
However, rising concerns among analysts regarding Oracle’s profit margins and dependency on its OpenAI partnership triggered a 21% stock decline, eroding part of his wealth.
Mark Zuckerberg experienced the biggest drop in wealth during October 2025. His net worth plunged by $29 billion to $223 billion as Meta’s third-quarter earnings missed expectations and its stock fell 12%. This setback reflected ongoing volatility in the social media sector and investor uncertainty over advertising and virtual reality ventures.
“Meta’s shares dropped 12%, cutting $29 billion from Zuckerberg’s net worth.”
In November 2025, shifting tech valuations propelled Elon Musk’s fortune to new highs while Ellison and Zuckerberg faced major equity losses tied to market confidence and corporate performance.
