Google Cloud's year-over-year revenue growth rate climbed from 32% to 82% over the past year, and the segment's operating income more than tripled, now making up 21.6% of Alphabet's total profits. Executives point to surging AI compute demand as the driver, with no sign yet of a slowdown.
Cloud growth keeps accelerating
Google Cloud's growth has caught investors and executives by surprise. Revenue rose 32% year over year in Q2 2025. It then accelerated to 34% in Q3 and 48% in Q4.
That acceleration continued into 2026. Growth surged to 63% year over year in the first quarter, then reached 82% in the second quarter. Google Cloud is now growing faster than Amazon Web Services and Microsoft Azure, and there are no signs a deceleration is coming.
Profitability is climbing just as fast. Google Cloud's operating income more than tripled year over year. The segment now makes up 21.6% of Alphabet's total profits.
AI workloads drive the compute crunch
Alphabet CEO Sundar Pichai told investors on the Q2 earnings call that the company's AI investments are "redefining what's possible across every part of our business." He used similar language in the Q1 press release, describing AI as lighting up every part of the business.
AI workloads and large language models such as ChatGPT and Grok have substantially increased demand for compute. That gives Alphabet more customers for Google Cloud's services, but it also gives the company flexibility to charge higher premiums for available compute capacity.
What it could mean for Alphabet's bottom line
If cloud growth continues at this pace, Google Cloud could produce half of Alphabet's total operating income within the next two to three years. The largest companies and enterprises are scrambling to gain market share and are willing to invest what is necessary to secure the extra compute they need, an environment that explains Alphabet's tremendous cloud growth.
