Alphabet’s advertising business missed expectations while AI costs continued to climb. Investors are beginning to question how much Google can spend transforming the business that made it rich.
Google has spent years turning internet searches into one of the most profitable advertising businesses ever created. Now it’s spending extraordinary amounts of money trying to change how people search, even as that transformation threatens the revenue paying for it.
Investors aren’t particularly thrilled with the arrangement.
Alphabet, Google’s parent company, reported $127.6 billion in third-quarter revenue, missing Wall Street’s $128.2 billion forecast. Advertising revenue reached $82 billion but fell approximately $1.4 billion short of expectations. On Thursday, Alphabet shares plunged 12.6%, their worst one-day decline in more than two decades.
The problem isn’t that Google can’t make money. It’s that the company is spending at a pace that makes even its enormous earnings look less reassuring.
Alphabet reported negative free cash flow of $9.1 billion during the quarter. It expects capital spending of $195 billion to $205 billion this year, much of it supporting artificial intelligence and cloud infrastructure, with additional increases anticipated in 2027.
That money is going toward data centers, specialized chips and the computing capacity needed to compete in an AI market where every major technology company wants to become indispensable.
And here’s the uncomfortable part: Google is investing heavily in technology that could disrupt its own advertising model.
Traditional search results give advertisers opportunities to reach consumers through sponsored links. But when Google’s AI Mode answers questions directly, users may have fewer reasons to click through to websites. Google is introducing advertising into those experiences, though monetization has not yet matched the economics of traditional search.
There is encouraging news. Google Cloud revenue more than doubled to $30.7 billion, demonstrating substantial demand for AI computing and related services. But rapid growth in one division doesn’t automatically erase the financial pressure building elsewhere.
Google is effectively financing two businesses at once: the search empire that generates much of its revenue and the AI infrastructure it believes will define the next generation of technology.
The question is whether the second can become profitable enough before it changes the economics of the first.
Wall Street’s reaction suggests investors are no longer satisfied with the promise that spending more on AI will eventually mean earning more from it. They want to see the money coming back.
