Mark Zuckerberg has dropped from second to sixth on the Bloomberg Billionaires Index, despite adding $23 billion to his net worth in under 15 months. The Meta CEO, whose company owns Facebook, Instagram, and WhatsApp, reached a net worth of $229 billion as of Wednesday’s market close. However, he has fallen behind several other tech leaders whose fortunes have grown even faster. Zuckerberg briefly overtook Amazon founder Jeff Bezos to become the world’s second-richest person in October 2024, trailing only Elon Musk by $50 billion at the time. Since then, Musk’s net worth has surged to $632 billion, widening the gap between them to more than $400 billion. This dramatic increase is largely driven by the soaring value of Tesla and SpaceX, with SpaceX’s valuation now estimated at $800 billion following a recent secondary share sale ahead of a potential public listing. Alphabet co-founders Larry Page and Sergey Brin have each added roughly $100 billion to their fortunes over the same period, pushing their net worths to $256 billion and $238 billion, respectively. That has elevated Page from seventh to second place and Brin from 10th to fourth on the list. Bezos’ wealth has grown by $39 billion to $244 billion, securing him third place. Oracle co-founder Larry Ellison, who briefly held the top spot in September, now ranks fifth with $231 billion, up $52 billion since last October. His position is bolstered by his nearly 50% stake in Oracle and significant holdings in Tesla. Despite gaining $11 billion to reach $204 billion, LVMH CEO Bernard Arnault has slipped from fourth to seventh place. Meanwhile, Meta’s stock has only risen 11% since October, significantly lagging behind Tesla’s 94% gain and Alphabet’s 78% surge. Amazon’s shares have climbed 22%, and Oracle’s have increased 7%, while LVMH’s gains have been minimal. The shift in rankings underscores how rapidly wealth is being reshaped by performance in the AI-driven tech market. While Zuckerberg’s personal wealth continues to grow, the outsized gains in Tesla and Alphabet stocks have propelled Musk, Page, and Brin to the top. Bezos and Ellison have also maintained strong positions due to their diversified stakes in high-performing companies. Zuckerberg now sits just $27 billion behind Page in second place, meaning his position could change quickly if Meta’s stock rebounds or if other factors shift. With the billionaire rankings so fluid, the race for the top remains far from settled.
