Nearly all wealth gained by world’s rich this year comes from AI

Nvidia co-founder Jensen Huang’s wealth has surged as a blistering rally in AI-related stocks pushed the chipmaker’s market value above Amazon.com ’s for the first time.

The rally has minted another billionaire in Huang’s own family — his cousin Lisa Su, chief executive officer of Nvidia competitor Advanced Micro Devices, who’s worth $1.2 billion after the stock doubled over the past year.

Two chipmaker billionaires in one family illustrates the scope of the artificial-intelligence craze, which has come to dominate the stock market and accounts for most of the wealth gained by the world’s richest people this year.
