How AI boom made US tech billionaires even richer
The AI wave in 2025 has sent US tech billionaires' fortunes soaring—together, their net worth jumped from $1.9 trillion to almost $2.5 trillion by the end of December.
Elon Musk led the pack, becoming the first person ever to cross $500 billion and landing at $645 billion.
Larry Page and Jeff Bezos weren't far behind, with their wealth climbing to $270 billion and $255 billion.

NVIDIA's CEO Jensen Huang saw his fortune jump by nearly $42 billion as demand for AI chips exploded, helping push NVIDIA's value to a staggering $5 trillion.
