All three big clouds sped up in 2026. Google Cloud is growing fastest, Azure is holding above 40%, and AWS posted its strongest growth in years. Growth rate and market share tell different stories, and next week’s earnings will add another data point.
The growth picture
| Provider | Q1 2026 growth | Q2 2026 growth |
|---|---|---|
| Google Cloud | 63% | 82% |
| Microsoft Azure and other cloud services | 40% | 43% |
| AWS | 28% | 37% |
For the quarter ended June 30, AWS revenue rose to $42.2 billion, and Microsoft’s Intelligent Cloud segment, which includes Azure, reached $39.3 billion. Microsoft does not report Azure revenue on its own. In Q1, AWS revenue was $37.6 billion and Google Cloud topped $20 billion.
Share is still a different story
Synergy Research’s Q1 2026 figures put AWS at about 28% of cloud infrastructure, Azure at 21% and Google Cloud at 14%, with Google edging toward 15% in Q2. Other trackers use different definitions and show larger shares for AWS and Azure, so compare like with like. Synergy’s data also showed the overall market passing $143 billion in Q2, its fastest growth in eight years.
Where to be skeptical
- Percentages flatter smaller bases. Adding 82% to a smaller business is not the same as adding 37% to the largest one.
- Capex is the cost of this growth. One industry tally has the three companies guiding to roughly $570 billion of combined 2026 capital spending, and all three have said they expect to stay capacity-constrained through at least the end of 2026.
- Markets are not rewarding growth by itself. Alphabet’s stock fell about 7% after its Q2 report despite the cloud surge.
- AI-driven backlogs concentrate risk. A large share of committed spend comes from a handful of AI labs.
What it means for buyers
- Expect capacity limits and allocation conversations for GPU-heavy workloads. Plan lead times.
- Use competition. Google’s growth pressure and Microsoft’s and AWS’s AI pushes give you negotiating room on committed spend.
- Keep portability where it is cheap: containers, open data formats, and infrastructure as code.
- Watch FinOps closely as AI usage grows; usage-based AI costs are the fastest-growing line for many accounts.
What to watch next
Alphabet and Microsoft report on October 28, and Amazon on October 29, per published earnings calendars. Check whether Azure holds above 40%, whether AWS sustains its acceleration, and what each says about capex and capacity.
