No. In Synergy Research Group’s Q2 2026 estimate of worldwide cloud infrastructure services revenue, Amazon Web Services (AWS) held 28% of the market and Microsoft 20%. Azure has not passed AWS on this measure. The figures capture market scale—not which provider offers the best value or fit for a particular customer.
What the latest market-share figures show
Synergy Research Group estimated that the cloud infrastructure services market generated $143.4 billion in revenue in Q2 2026, up 43% year over year. Its category includes infrastructure as a service (IaaS), platform as a service (PaaS), and hosted private cloud services; it is not a measure of all cloud software or public IaaS alone. Synergy’s July 30, 2026 release also put trailing 12-month revenue at $500 billion.
| Provider | Q2 2025 share | Q2 2026 share | Change |
|---|---|---|---|
| AWS | 30% | 28% | Down 2 percentage points |
| Microsoft | 20% | 20% | No change |
| Google Cloud | 13% | 15% | Up 2 percentage points |
These are like-for-like Q2 estimates from Synergy’s series: Q2 2025 and Q2 2026. A falling share does not mean a provider’s revenue fell: a company can grow its revenue while losing share if the market grows faster.
Is Azure catching up to AWS?
The year-over-year comparison shows Microsoft holding steady at 20% while AWS declined from 30% to 28%. That narrows the gap, but AWS remained eight percentage points ahead in Q2 2026. Google Cloud gained two points over the same period.

The market itself is expanding rapidly. Synergy reported 165% year-over-year growth in GenAI-specific cloud services and attributed much of the broader acceleration to generative AI. John Dinsdale, Synergy’s chief analyst, said in the Q2 2026 release: “AI technology has lit a fire under the cloud market and is now driving unprecedented growth.” Fast growth in a segment does not, by itself, establish that Azure will overtake AWS.
Why different reports may give different answers
Market-share percentages depend on what a report counts and how it measures the market. Synergy’s figures are estimates of worldwide revenue across its defined cloud infrastructure services category. They should not be blended with a survey of what organizations use or spend, or with another analyst’s differently defined market.
Rank #2
- Survey findings: Flexera’s 2026 State of the Cloud describes respondents’ use and spending across AWS and Azure as closely matched, with no clear near-term trend toward one becoming dominant. That reflects surveyed organizations, not a global revenue-share estimate. Read Flexera’s report information.
- A different analyst series: Omdia’s Q4 2025 analysis also described AWS as the leader and Azure as second, but its scope includes BMaaS, IaaS, PaaS, CaaS, and serverless services hosted by third parties and available over the internet. Its percentages are not directly interchangeable with Synergy’s. Read Omdia’s release.
When comparing estimates, check the market definition, period, measurement method, and whether the figure refers to revenue share, growth, or survey responses. Those distinctions can change the number without making one report a direct contradiction of another.

A larger share indicates greater scale under the report’s definition. It does not establish better quality, customer satisfaction, lower prices, or a better fit for your workload. The market-share data cannot identify a universal winner for a business or individual project.

Quick Recap
Best Value
- Total cost: Include compute, storage, data transfer, support, and the cost of operating the service.
- Existing systems and skills: Account for compatibility with your current tools and the experience of the people who will manage the environment.
- Data and location needs: Check where data must be stored and which regions and services meet those requirements.
- Service and migration constraints: Evaluate reliability and other workload requirements alongside the effort and risk of moving or maintaining systems.
