Nvidia Corp. is facing rising concerns that its stranglehold on the market for semiconductors used in artificial intelligence computing is slipping. And that skepticism is now showing up in the stock market.

Shares of the chipmaker fell 2.6% on Tuesday following a report suggesting that Alphabet Inc.’s AI processors are gaining ground. While the stock rose 2.2% on Wednesday, shares remain down 10% this month, erasing more than $500 billion in market value, as investors grow increasingly fearful of a bubble in AI spending as well as Nvidia’s circular investments in startups like OpenAI that are also customers.

The slump has left the chipmaker trading at less than 26 times profits projected over the next 12 months, down from about 34 times at the start of this month.

“Nvidia’s valuation was really based on the idea that it would maintain its market share,” said Adam Sarhan, chief executive officer of 50 Park Investments. “If it starts losing some market share, then investors will reassess what growth could look like, and what kind of valuation it should have.”
