Wall Street Wiped $500 Billion Off Alphabet in a Day as AI Spending Drained Its Cash and Search Came Up Short

Alphabet just had the worst day in its history as a public company. Shares fell 13% on Thursday, erasing roughly $500 billion of market value and blowing past the previous record drop of 11.63% from March 2020.

Investors got two things they did not want in the same report. AI spending pushed free cash flow deep into the red, and search, the business that pays for all of it, came up short.

A rare double miss

Free cash flow came in at negative $9.07 billion for the third quarter, far worse than analysts expected. Alphabet did not offer relief on spending either, keeping its full-year capex guidance at $195 billion to $205 billion.

The top line disappointed as well. Revenue was $127.57 billion against a $128.2 billion consensus, and earnings per share were $2.12 against the $3.02 Wall Street expected.

Search advertising grew 12% to $63.35 billion, a number most companies would frame on the wall. Analysts wanted about $64.9 billion. Google Cloud grew 103%, and it did not save the day.

The AI Mode problem

The search miss is what makes this more than a bad quarter. Chief business officer Philipp Schindler said the impact came partly from lower monetization within AI Mode, and that Alphabet is now "scaling" ads in AI Overviews and AI Mode, including internationally.

In other words, Google's answer to the AI threat currently earns less than the product it is meant to protect. "Our view is that clearly there is some effect from consumers interacting with less advertising when they go to Google search and use Google AI," said Pivotal Research CEO Jeffrey Wlodarczak.

Ben Barringer of Quilter Cheviot was harsher. He described "a fairly messy set of results and a poorly handled earnings call," and argued that the company is stuck: "The problem for Google is it faces an innovator's dilemma and doesn't know whether to protect its core business or look to join the disruption."

Not everyone is convinced the sky is falling. "I don't think it's a sea change," Rosenblatt's Scott Devitt said on CNBC, arguing that 4 billion search customers who become AI customers leave Alphabet "in an enviable position."

Microsoft spent too, and kept its cash positive

The sharpest contrast came from the other big report. Microsoft's capex and finance leases rose 30% to $45.2 billion, below the $50.67 billion projected. Its free cash flow fell 27% to $18.63 billion, but it stayed positive, and the shares traded roughly flat.

Barringer's read was that Microsoft "is building out its architecture in a measured way and as such contains fewer surprises."

Alphabet is not alone on the wrong side of that line. Meta reported negative free cash flow for the first time in years last week, and its stock was punished as well.

The result is a market that has stopped applauding AI budgets on sight. Nasdaq futures slid about 1% on the results as spending fears returned, weeks after Goldman's top strategist warned that AI capex is creating an earnings bubble.

For Alphabet, the price of spending past its cash flow while search fell short was $500 billion in a single session.
