Forbes October 1 Ranking Shows Seven of the Top Ten Billionaires Changed Positions in the Past Month
Jeff Bezos Returns to Second Place with $370 Billion
Forbes' ranking as of October 1 shows that seven of the top ten billionaires in the world changed positions in the past month. Jeff Bezos rose from third to second place, with a net worth of approximately $370 billion, an increase of about $102 billion over the month, marking his return to second place for the first time since May 2025.
The rise is attributed to private valuations, not Amazon's stock price on that day. Blue Origin was valued by private investors at over $130 billion, and industrial AI company Prometheus at over $41 billion. He became the fourth person in history to surpass a net worth of $300 billion, following Elon Musk, Larry Page, and Larry Ellison.
Page dropped from second to third. He had held second place continuously for ten months but saw his wealth increase by only about $8 billion to $286 billion this month. Sergey Brin fell from fourth to fifth, with an increase of about $7 billion to $263 billion.
Michael Dell rose from fifth to fourth, with an increase of about $28 billion to $268 billion. Dell Technologies' stock price rose 18% over the month, driven by demand for AI servers. Jensen Huang moved up from eighth to seventh, while Larry Ellison dropped from seventh to eighth. Warren Buffett entered the top ten at tenth place. Mark Zuckerberg remains sixth, and Steve Ballmer remains ninth.
Elon Musk retains the top position with about $936 billion, an increase of about $44 billion over the month, driven by SpaceX and Tesla. Bill Gates has not returned to the top ten since his wealth was adjusted down in October 2024. Forbes notes that stock prices are changing these numbers daily.
The buyers are private investors and stock buyers revaluing Blue Origin, Prometheus, and AI servers, while the sellers are shareholders who have been pushed down in the rankings. The event is driven by month-end valuations. Funds are shifting from slow increases in cloud and advertising stocks to rockets, industrial AI, and servers, benefiting Bezos and Dell's equity that received new private valuations, while Page and Brin, who rely solely on Google stock, are under pressure as their increases are not enough to surpass others.

Jeff Bezos founded Amazon in 1994 and Blue Origin in 2000, and after stepping down as CEO of Amazon, he divided his time between rockets and later projects. Forbes has placed him second this time not due to retail cash flow, but due to private valuations of Blue Origin exceeding $130 billion and Prometheus exceeding $41 billion. His last time at second was in May 2025.
The capital path is the repricing of unlisted assets. Amazon's stock is fluctuating daily, but the real change in rankings comes from the two private companies. Michael Dell's $28 billion increase comes from the publicly listed Dell, which rose 18% in a month, driven by AI server purchases. Page and Brin's wealth is also increasing, but their increases of $8 billion and $7 billion are not enough to surpass others, thus ending Page's ten-month run at second.
A comparable situation is when Bezos briefly surpassed Musk at Amazon's stock peak in 2021, and Ellison moved in and out of the top five with Oracle holdings. The current situation reflects a rotation in valuations, not a disappearance of wealth. Seven positions in the top ten have swapped, while Zuckerberg and Ballmer remain unchanged, indicating that the monthly fluctuations in advertising and Microsoft software are not enough to change rankings. Buffett's entry into tenth place is due to others vacating that position.
Structurally, this represents a shift in pricing power. The monthly pricing power of the billionaire list has temporarily shifted from daily traded internet equities to rockets and industrial AI that can be revalued in one go by private equity. If Blue Origin and Prometheus do not maintain their next round of valuations, second place will revert to those holding tradable stocks. The first place with $936 billion did not participate in this rotation.

When rankings change, it often means others' valuations are rising faster.
Private pricing can rewrite a decade's second place in a month.
Wealth increases can still lead to drops in rank as long as the increase is not sufficient.
