Alphabet股价暴跌12%市值蒸发5000亿美元

In tonight's future of everything, Google's biggest AI challenge might not be building the technology, but figuring out how to make money from it. Shares of Google's parent Alphabet plunged more than 12% today, marking the company's worst one-day stock performance on record and wiping out more than $500 billion in market value. But the sell-off wasn't limited to Google. Will that drop spread across other parts of the tech sector as investigators are now starting to ask those questions about whether all this money being poured into AI is going to pay off quickly enough to justify all of the costs.

NBC's Alli Canel has more.

The worst day ever for Alphabet.

Google is absolutely crashing through the floor right now. Shares of the company behind Google, YouTube, and the AI chatbot Gemini plunging double digits today, erasing more than $500 billion in value, making it the second largest single day wipeout for any single stock in history, behind only Nvidia's nearly $600 billion plunge last year, sparked by the rise of China's Deepseek. The drop of more than 10% adding to growing anxiety on Wall Street.

Is the AI bubble set to pop? Amazon stock also plummeting after hours this evening due to a lackluster earnings report. It's all dragging down the broader market even as stocks hover near record highs thanks largely to AI. Ironically, Google's own AI technology is part of the problem. More people are using its AI search features, but the company says those searches aren't generating as much ad revenue. On a call with investors, its CEO emphasizing that getting people to use its AI search features comes first and making money from them comes second.

Just like our shift to mobile over a decade ago, we are focused on building the best search user experience followed by monetization.

Despite the Gemini app having more than 1 billion users, that wasn't what investors wanted to hear. And the cost of building out AI continues to soar. Tech giants pouring in hundreds of billions of dollars from building data centers to buying advanced chips.

We're literally at the beginning of a new industrial revolution.

Both Google and Amazon holding spending projections mostly steady this week, adding to the anxiety.

This may be one of the biggest investment cycles ever. And the the market at some point, and I think it already is, is sort of questioning when we start getting returns. And that massive AI spending plan starting to hit the workforce.

AI is not like a sort of a technology. It's the future of the firm.

That's Microsoft CEO earlier this year. This week, the company offering voluntary buyouts to some 60,000 eligible employees. It all comes as concerns grow over AI taking human jobs.

Some jobs are just going to become less relevant. I think that happens with any sort of major technology innovation. Even non- tech companies from Kroger to Barclays to American Express also announcing job cuts this month as they expand or prepare for AI.
