Alphabet's $100 Billion Stock Swoon Shows AI Stakes Are Rising

The stakes in the race for generative AI are rising.

The fervor in the stock market bubbling around artificial intelligence spread this week to Microsoft Corp. and Alphabet Inc., which despite investing heavily in the technology had so far been ignored by traders in favor of smaller, more speculative companies.

Google parent Alphabet’s shares tumbled 7.7% on Wednesday after concerns surfaced about the competency of Bard, the ChatGPT rival it unveiled on Feb. 6. The rout was the worst for the stock in more than three months and erased more than $100 billion in market value.

The fact that the selloff was far bigger than the 2.8% drop the day after Alphabet’s earnings missed estimates shows how important success in the AI arms race has become for investors.

“For a stock like Google to get knocked down this much, it just shows you that people aren’t even looking at the fundamentals,” said Matt Maley, chief market strategist at Miller Tabak + Co.
