Warren Buffett: “AI investment is not a bubble…this kind of money wouldn’t even go into building a railroad network”

Warren Buffett said the AI spending by Meta, Microsoft, Amazon, and Alphabet looks more like future infrastructure building than a bubble.

In a CNBC interview, he compared investment in data centers, chips, and networks to building a railroad system.

Buffett pushed back on the idea that Big Tech’s massive AI capital spending is overheating.

His remarks frame the AI boom as a contest over financial strength and infrastructure capability, not just hype.
