Investors debate whether AI stocks are in a bubble as spending grows

In short: More investors are warning that AI stocks may be overpriced, but many big tech and finance figures say the boom is still worth it.

What's going on

Worries about an “AI bubble” are rising on Wall Street. In Bank of America surveys, AI is repeatedly listed as the top “tail risk,” meaning a danger that might not happen often, but could cause big damage if it does (like a rare storm that can still flood a town). In several recent polls, roughly 40% to 54% of fund managers said AI-related stocks are already in bubble territory.

People pointing to a bubble cite a few main concerns. One is that stock prices for some AI-linked companies have climbed faster than their actual profits. Another is that market gains have been driven by a small group of large tech companies, which makes the market more fragile if those few stocks fall. A third concern is heavy corporate spending on AI infrastructure, like data centers and computing power, before it is clear how much money that spending will bring back.

At the same time, some prominent leaders say the bubble talk is overblown or even useful. JPMorgan Asset Management CEO Mary Callahan Erdoes has called the idea that AI is a bubble “absurd.” Others, like OpenAI CEO Sam Altman, have said there is a bubble element, but argue that overinvestment is common in new technologies, and the failures help reveal which companies are actually strong.

What to watch

If AI-linked stocks drop sharply, it could spread to the broader market, which is why central banks and large financial firms are paying attention. For everyday investors, the key issue is whether AI companies can turn today’s spending into steady earnings over time.
