Revenue rose 25% to $127.6bn, and Google Cloud more than doubled. Even so, Alphabet's shares fell by more than 10% in after-hours trading on Wednesday, erasing tens of billions of dollars from a company valued at $4tn. The explanation lies in the gap between the top line and the bottom line.
Net profit fell 25% to $26.2bn in the July-to-September quarter, well short of analysts' forecasts. Part of the damage was an $8.7bn loss on equity investments, which Alphabet blamed on its stake in SpaceX, whose shares have struggled since it went public in June.
Meanwhile, the core advertising machine is slowing. Advertising revenue grew 11% to $82bn, and search growth eased from 17% to 12%. YouTube advertising rose 9%, down from 13% a quarter earlier, although the platform is now the most-watched content provider on American television screens. The brightest spot was Google Cloud, where revenue jumped 103% to $30.
7bn and operating income tripled to $11.1bn. Sales of Google's in-house AI chips, known as TPUs, contributed significantly. Alphabet is also selling them to outside companies, a growing challenge to Nvidia, and OpenAI reportedly plans to buy some.
The cost of this ambition is striking.
