• Alphabet shed around $500 billion in market value on Thursday after its stock tanked 13%.
• If the losses persist, it will be the second-largest one-day drop in market cap for any company.
• Shares of Google's parent company fell after its earnings disappointed investors.

Alphabet is on track to suffer its biggest-ever one-day market-cap wipeout, and the second-largest value drop in stock-market history.

Shares of Google's parent company slumped by as much as 13.5% in early trading on Thursday, slashing Alphabet's market capitalization by over $500 billion, from around $3.9 trillion to $3.4 trillion.

If the losses persist until the close, it would be the second-largest one-day loss of market capitalization ever. Only AI chipmaker Nvidia has lost more value in a single day, when it shed close to $600 billion on January 27, 2025, on fears that China's DeepSeek would steal its lunch.

Alphabet's shares slumped after its earnings report on Wednesday showed about $9.1 billion in negative free cash flow as it spent heavily on AI infrastructure, and profits that fell short of Wall Street's forecasts.

Google's AI search revenue also lagged expectations, despite CEO Sundar Pichai saying on the earnings call that AI helped search queries grow at the fastest year-over-year pace in five years.

Search revenue of $63 billion came in below analysts' estimates and was virtually flat compared to the previous quarter.

That came as a shock because search revenue had beaten Wall Street's estimates in each of its four previous quarterly earnings reports.

"It's worth noting that the strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode," Philipp Schindler, Google's chief business officer, said on the call.

He also announced that Google is introducing ads in AI Mode to more users, including in international markets for the first time.

The rise of generative AI has shaken up Google's core business as chatbots like ChatGPT and Claude give people an alternative way to search. While Google has its own chatbot, Gemini, and has integrated it into its search engine with AI Mode, revenue is lagging behind its popularity.

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

As well as one of the market's biggest-ever single-day value losses, if Alphabet stock closes more than 9.77% lower on Thursday, it would be the company's worst post-earnings percentage drop since going public in 2004.

"In the AI trade you need a clean story to pique investor interest. But it only matters if numbers track in the right direction," Mark Shmulik, a senior analyst at Bernstein, wrote in a note.

"Is Google an AI winner? Probably, but not today."

• Elon Musk says it's "pointless" to save for the long term, as he expects "super intelligent abundance."
• The Tesla and SpaceX CEO was replying to an X user who said they'd stopped stressing about spending.
• Musk previously said that if he's right about the future, "saving for retirement will be irrelevant."

Elon Musk says it's not worth saving for the long term, as nest eggs won't matter.

"Saving money for the distant future is pointless with the advent of super intelligent abundance," Musk said in an X post on Thursday, doubling down on one of his most polarizing predictions.

The Tesla and SpaceX CEO was replying to a user who said they weren't stressing over their "questionable financial decisions" because a future of abundance meant "most of it won't matter in a few years anyway."

The world's richest person — who has a nearly $1 trillion net worth — has previously advised against saving for decades to come.

"Don't worry about squirreling money away for retirement in 10 or 20 years," Musk said during a podcast episode released in January. "It won't matter."

"If any of the things that we've said are true, saving for retirement will be irrelevant," he added.

Musk said at the time that he expects progress in AI, energy, and robotics to supercharge productivity, resulting in plentiful resources so that "anyone can have whatever stuff they want."

In that world, he continued, everyone would have access to "better medical care than anyone has today," there would be "no scarcity of goods and services," and "you can learn anything you want about anything for free."

Business Insider spoke to seven personal finance and AI experts about those comments, and they all agreed people should keep saving for retirement given the risk that Musk may be wrong.

Musk laid out an even more utopian vision on a recent podcast, predicting that advances in robotics and space travel would lead to a multiplanetary economy, at which point "money becomes irrelevant" and "conventional currency will not matter."

Several other tech leaders have predicted AI and other technologies will transform the way we live.

Microsoft cofounder Bill Gates said on a recent podcast episode that AI will lead to "true abundance" with robots able to "build houses, grow food, do surgery."

But he also warned the next two decades will be "as tumultuous a period as there's been in human history," as technological advances will mean "none of the things that human labor provides to the economy will be necessary for most goods and services."

Similarly, Musk has predicted a "bumpy" transition to a brighter future. He's suggested government checks for all as the best solution to AI-fueled job destruction.
