Alphabet’s AI spending spree turns its search empire into a $500bn sell-off
Investors saw a warning that AI is eroding Google’s most valuable profit engine just as spending surges; Alphabet sees the same transition as a costly but necessary route to stronger search demand and a rapidly expanding cloud business.
Alphabet’s third-quarter results landed after Wednesday’s market close with a collision at their heart: Google is investing heavily to win the AI race while its core search business is becoming harder to monetize.
The company reported search-and-other revenue of roughly $63bn, up 12% year on year but below forecasts for a second straight quarter. Growth had slowed from 19% in the first quarter and 17% in the second. Chief Business Officer Philipp Schindler acknowledged that AI Mode queries generated “lower monetisation” through ads, sharpening fears that conversational answers may cannibalize the traditional link-based search model.1
Alphabet’s own case is that AI is expanding usage, not hollowing it out. Sundar Pichai said the company’s investments were driving overall and commercial search-query growth, with the year-on-year rate at its strongest in five years.
2 Schindler also said Gemini was being deployed across Google’s advertising infrastructure to improve performance, while Alphabet’s cloud revenue more than doubled to $30.7bn as customers sought AI services and computing capacity.1
But the bill arrived before the payoff. Free cash flow fell to minus $9.1bn in the September quarter as capital expenditure reached $51.3bn; Alphabet maintained full-year capex guidance of up to $205bn. Investors also focused on search revenue missing estimates and the prospect that spending could climb further.3
By Thursday, the verdict was brutal: shares fell about 13%, erasing a record $500bn in market value. The contrast with Microsoft was hard to miss: it spent heavily too, but still produced $18.6bn in free cash flow. “Markets are carefully calibrating the trade-off between capex and free cash flow,” SLC Management’s Dec Mullarkey said; in that test, Google “fell short.”3
The immediate panic does not settle whether AI has permanently damaged search. It does establish what investors now demand from Alphabet: evidence that its vast AI outlay can turn growing queries and cloud contracts into cash before its legacy advertising moat narrows further.
