Is the stock market in an AI bubble? A recent warning sign suggests yes

Are we in an AI bubble, similar to the dot-com bubble which burst in the early 2000s? Stock market analysts have been sounding the warning bells for the last year, but those warnings just got louder—and some are saying a resounding yes. One thing that’s got market watchers worried: While the S&P 500 closed out May on a record high (largely driven by semiconductors), only a few of those 500 companies—just 20 to be exact—hit their own all-time highs. That’s a similar pattern that occurred during the dot-com internet bubble, according to CNBC.

After driving up the market, including the Nasdaq five-fold, the market collapsed by nearly 77% by October 2002. Many companies went bankrupt, spurring a mass exodus from Silicon Valley. Today, we are seeing artificial intelligence startups like Anthropic and OpenAI raise billions for their upcoming IPOs, while at the same time many tech companies are spending an unprecedented amount to build massive AI da
