A recent plunge in tech shares reshaped the Forbes ranking of the world’s wealthiest people. The shift is worth reading because it highlights why Warren Buffett’s investment style kept him uniquely positioned among the richest.

Larry Ellison, co‑founder of Oracle, saw his estimated net worth drop by roughly $11 billion to $153.3 billion after Oracle shares fell about 7 %, pushing him down to 11th place on the Forbes list. At the same time, Dell Technologies’ share slump cut CEO Michael Dell’s wealth by $22 billion, Nvidia’s 9 % slide erased $15.8 billion from Jensen Huang’s fortune, and Tesla’s 11.5 % plunge removed $79.4 billion from Elon Musk’s net worth, although Musk remains the world’s richest man.

Warren Buffett, chairman and CEO of Berkshire Hathaway, saw his wealth shrink by $2.4 billion to $162.2 billion, keeping him inside the top ten and moving him up to eighth place on the Forbes ranking. His fortune comes from the shares he owns in Berkshire Hathaway, and he had avoided tech stocks for most of his career, although Berkshire now holds stakes in IBM, Apple and, more recently, Alphabet.

Amancio Ortega, the Spanish founder of fashion group Inditex, is the only other billionaire in the top ten whose fortune does not come from technology. Like Buffett, his wealth is built on retail and real‑estate assets.

The tech sell‑off shows how dependent the richest rankings are on the performance of technology companies. Buffett’s long‑term, non‑tech focus allowed his wealth to stay relatively stable, leaving him the sole non‑tech billionaire among the world’s ten richest.
