0:25Fleury reports growing investor concern about AI infrastructure spending and slowing search advertising growth.
1:52Mahaney says major investment programmes pressure short-term free cash flow despite strong cloud growth.
3:02Google's particular challenge is preserving its search business and monetising it in an AI format, Mahaney explains.
4:10Mahaney predicts a temporary sell-off, pointing to enterprise demand and cloud revenue guidance.

Google is trying to change how people search without weakening the business that pays for it. That dilemma sits at the centre of BBC News's report on a sell-off that, the broadcaster says, wiped just over $500 billion from parent company Alphabet's market value.

The report drew roughly 51,000 views in its first three hours today. It pairs business correspondent Michelle Fleury's account of investor unease with a more optimistic assessment from Mark Mahaney, senior managing director at Evercore ISI.

Fleury reports that Google's AI search summaries are affecting advertising revenue, with search advertising still growing, but more slowly than in the previous quarter. The distinction matters: this is not a report of revenue collapsing. Alphabet's overall revenue rose by a quarter compared with a year earlier, according to the BBC, even as its shares fell sharply.

"They're willing to bet big on AI, but increasingly want to see the returns," Fleury says of investors.

Mahaney separates Google's search problem from the wider spending question. Meta, Alphabet and Amazon are undertaking enormous investment programmes, he says, putting short-term pressure on free cash flow while their cloud businesses show strength. For Google specifically, the challenge is preserving its core search engine and making money from its AI format.

Asked whether the sell-off signals a sustained retreat from AI investments, Mahaney offers a forecast rather than a certainty: "My guess is this is going to be a blip." His case rests on enterprise demand and cloud revenue guidance, not a dismissal of Google's advertising difficulties.
