AWS vs Microsoft Azure Statistics 2026: Revenue, Growth and Share

Amazon Web Services (AWS) segment sales increased 37% year-over-year to $42.2 billion in the second quarter ended June 30, 2026. Microsoft’s Azure and other cloud services revenue increased 43% in the same quarter. AWS remained the leader in the global cloud infrastructure market in Q4 2025 with a 32% market share, and Microsoft Azure remained the second-largest provider with a 22% market share, according to Omdia. These AWS vs Microsoft Azure statistics pair company filings with analyst estimates.

Azure grows faster and AWS books more revenue, a contrast clearest over one shared window. AWS posted $148.4 billion in trailing-twelve-month net sales at Q2 2026, against $137.8 billion in Intelligent Cloud revenue for Microsoft’s twelve months ended June 30, 2026. Intelligent Cloud is wider than Azure alone, so each comparison below names its Microsoft line.

What is Amazon’s cloud computing revenue?

AWS segment sales were $42.2 billion in the second quarter ended June 30, 2026, a $169 billion annualized revenue run rate. Over the trailing twelve months at Q2 2026, AWS net sales totaled $148.4 billion. AWS segment operating income was $16.6 billion in the quarter, compared with $10.2 billion a year earlier.

Microsoft’s quarterly releases give Azure a growth rate rather than a dollar figure, so the dollar comparisons use Intelligent Cloud.

About This Data

Compiled from 15 sources: 9 company filings and earnings releases from Amazon and Microsoft, 2 company infrastructure pages from AWS and Microsoft Azure, and 4 analyst press releases from Omdia and Gartner. Publication dates run from June 2025 to October 2026. Only company disclosures and named analyst releases qualified. Figures are reviewed on a rolling basis and updated when the companies or analysts publish new editions.

AWS vs Azure Growth Rate by Quarter

• Azure and other cloud services revenue increased 43% in the quarter ended June 30, 2026, against AWS net sales growth of 37% excluding foreign exchange in Q2 2026.
• Azure and other cloud services revenue increased 40% (up 39% in constant currency) in the quarter ended September 30, 2025, when AWS net sales grew 20% excluding foreign exchange in Q3 2025.
• Azure’s growth lead stood at 20 points in Q3 2025 and narrowed to 6 points in Q2 2026.
• AWS net sales growth excluding foreign exchange rose from 17% in Q2 2025 to 37% in Q2 2026.
• Azure and other cloud services revenue grew 39% in the quarter ended June 30, 2025, so the gap a year earlier was 22 points.

Amazon’s series strips out currency moves while Microsoft’s headline Azure rate is as reported, so a one-point gap either way sits inside the difference in method. Faster growth has not yet changed the order of the market.

Recent Developments

• As listed in October 2026: The AWS Cloud spans 124 Availability Zones within 39 Geographic Regions, with announced plans for 7 more Availability Zones and 2 more AWS Regions in the Kingdom of Saudi Arabia and Chile, per AWS’s infrastructure page.

AWS vs Azure Market Share

• AWS led the global cloud infrastructure market in Q4 2025 with a 32% market share and 24% year-over-year revenue growth.
• Microsoft Azure remained the world’s second-largest cloud service provider in Q4 2025, with a 22% market share and year-on-year revenue growth of 39%.
• Microsoft Azure delivered year-over-year growth of 33% in Q1 2025, when it remained the second-largest cloud provider.
• AWS, Microsoft Azure and Google Cloud together accounted for 66% of global cloud infrastructure spending in Q3 2025.
• Google Cloud delivered year-on-year growth of 50% in Q4 2025 and expanded its market share to 12%.

A larger revenue base needs less growth to hold its dollar lead, and share only means something against the size of the market it divides.

Cloud Infrastructure Spending Statistics

• Global spending on cloud infrastructure services reached $110.9 billion in Q4 2025, reflecting year-on-year growth of 29%, according to Omdia.
• Q4 2025 marked the sixth consecutive quarter in which the market expanded by more than 20%.
• Spending grew 25% year on year in Q3 2025, the fifth consecutive quarter in which growth in spending on cloud infrastructure services remained above 20%. Infrastructure services are one slice of the wider cloud computing market.
• Quarterly spending rose 22.0% between Q1 2025 and Q4 2025.

Gartner’s annual IaaS figures give a longer view.

AWS vs Azure vs Google Cloud IaaS Market Share 2024

• The worldwide infrastructure as a service (IaaS) market grew 22.5% in 2024, reaching $171.8 billion, according to Gartner.
• Amazon continued to lead the worldwide IaaS market with revenue of $64.8 billion and 37.7% market share.
• Microsoft followed with 23.9% market share in 2024, up from 23.0% in 2023.
• Microsoft’s IaaS revenue grew 27.6% from 2023 to 2024, against 18.6% for Amazon.

Who are the 5 biggest cloud providers in the world?

Amazon retained the No. 1 position in the IaaS market in 2024, followed by Microsoft, Google, Alibaba and Huawei, by Gartner’s count. In 2024, the top five IaaS providers accounted for 82.1% of the market. Gartner’s 2024 figures are over a year old and cover IaaS only, so they do not compare directly with Omdia’s shares.

Analyst shares are estimates. The companies’ own annual filings show the totals.

AWS vs Azure Annual Revenue

• AWS net sales reached $128.7 billion on a trailing-twelve-month basis at Q4 2025, the full calendar year.
• AWS net sales grew 41.8% from 2023 to 2025.
• AWS operating income rose from $24.6 billion in 2023 to $45.6 billion in 2025.
• Microsoft’s Azure revenue surpassed $100 billion for the first time in fiscal 2026.

Amazon reports AWS on calendar years and Microsoft on fiscal years that close mid-year, so read the two series below as trends, not matched pairs.

• Server products and cloud services revenue increased $31.0 billion or 31% in fiscal 2026, driven by Azure and other cloud services.
• Azure and other cloud services revenue grew 41% in fiscal 2026.
• Azure surpassed $75 billion in revenue in fiscal 2025, up 34%.
• Server products and cloud services revenue was $129.4 billion in fiscal 2026.

Revenue shows scale. Operating income shows what each cloud keeps.

AWS vs Azure Operating Margin

• AWS operating margin was 39.4% of AWS net sales in Q2 2026, up from 32.9% in Q2 2025.
• AWS’s trailing-twelve-month operating margin stood at 36.8% at Q2 2026.
• Intelligent Cloud operating income was $16.0 billion on revenue of $39.3 billion in the three months ended June 30, 2026, an operating margin of 40.6%.
• Intelligent Cloud operating income rose to $57.0 billion in the twelve months ended June 30, 2026, from $44.6 billion a year earlier, an operating margin of 41.3%.

By the numbers: AWS earned $54.7 billion in operating income over the trailing twelve months at Q2 2026, a 36.8% margin on AWS net sales. Microsoft’s Intelligent Cloud earned $57.0 billion in operating income in the twelve months ended June 30, 2026. Intelligent Cloud also carries server licenses, so its margin is not an Azure-only margin.

Both companies are reinvesting that profit at a pace the filings make visible.

AWS vs Microsoft Cloud Capex

• Amazon’s purchases of property and equipment, net of proceeds from sales and incentives, reached $169.0 billion over the trailing twelve months at Q2 2026, up 64%.
• Free cash flow decreased to an outflow of $7.6 billion for the trailing twelve months, and Amazon said the higher spending primarily reflects investments in artificial intelligence.
• Microsoft’s additions to property and equipment were $115.9 billion in the twelve months ended June 30, 2026.
• Microsoft’s additions to property and equipment were $35.8 billion in the three months ended June 30, 2026, against $17.1 billion a year earlier.
• Omdia reported that AWS expects capital expenditure to reach $200 billion in 2026, more than 50% above the nearly $132 billion recorded in 2025.

Worth noting: Amazon’s free cash flow outflow was driven primarily by a year-over-year increase of $66.1 billion in purchases of property and equipment, a company-wide figure rather than an AWS-only one. Omdia cites Microsoft quarterly capital expenditure of $37.5 billion, a different basis from the cash-flow line in the table.

The spending is aimed at AI, and both companies now report what AI earns.

AWS vs Azure AI Revenue Run Rate

• AWS’s AI business exceeded a $25 billion annual revenue run rate in Q2 2026, with triple-digit year-over-year growth.
• Within Microsoft’s Copilot business, Microsoft 365 Copilot reached over 30 million paid seats in fiscal 2026.
• On Amazon Bedrock, customers spent more in Q2 than all prior quarters combined, per Amazon’s Q2 2026 results.

Amazon’s run rate covers AWS’s AI business, while Microsoft’s is company-wide and one quarter older. Contracted future revenue shows how much of that demand is already signed.

AWS vs Azure Backlog and Contract Commitments

• For contracts with original terms that exceed one year, Amazon’s commitments not yet recognized, primarily related to AWS, were approximately $496 billion as of June 30, 2026.
• The weighted-average remaining life of Amazon’s long-term contracts is 6.4 years.
• In its OpenAI commercial arrangement, AWS expanded an existing $38.0 billion multi-year commitment by $100.0 billion over 8.0 years in Q1 2026.
• AWS ended Q4 2025 with a total backlog of $244 billion, according to Omdia.
• Microsoft’s commercial remaining performance obligation increased 84% to $678 billion in its fiscal fourth quarter.

Source: Omdia Q3 and Q4 2025 releases, Amazon.com Form 10-Q, Microsoft Form 10-K for fiscal year 2026

Key finding: Amazon’s Form 10-Q put commitments not yet recognized for contracts with original terms that exceed one year, primarily related to AWS, at approximately $496 billion as of June 30, 2026. That total sits alongside an Anthropic expansion of more than $100.0 billion over 10.0 years. Omdia’s quarterly AWS backlog figures come from a different disclosure, so they stay separate rows.

Serving that backlog depends on physical footprint.

AWS vs Azure Regions and Availability Zones

• The AWS Cloud spans 124 Availability Zones within 39 geographic regions.
• AWS global infrastructure is built with three Availability Zones (AZs) per Region.
• AWS’s global network backbone uses nearly 20 million kilometers of fiber optic cabling.
• Microsoft lists 80+ Azure regions and 500+ datacenters, and says Azure has more regions than any other cloud provider.

Source: AWS Global Infrastructure and Azure global infrastructure pages, October 2026

How is Azure different than AWS?

On footprint, the two companies count different units. AWS reports Availability Zones within Geographic Regions, with three Availability Zones per Region, while Microsoft reports 80+ Azure regions and 500+ datacenters. A region on one platform is not the same unit as a region on the other, so the counts are not a ranking.

Neither company publishes a total customer count in the sources cited here, but both disclose usage markers.

AWS vs Azure Customer Statistics

• For Elastic Compute Cloud (EC2), Graviton is used by 98% of the top 1,000 EC2 customers.
• Hundreds of thousands of customers now use Bedrock, and more customers were added in the last six months than in the first two years after launch.
• Azure AI Foundry now serves more than 80,000 customers, according to Omdia’s Q3 2025 release.

Source: Amazon.com Q2 2026 results, Omdia Q3 2025 release

These markers measure adoption of specific services, not total customers, so they show where each platform is growing rather than which one has more users.

Conclusion

AWS segment sales increased 37% to $42.2 billion in the second quarter ended June 30, 2026, while Azure and other cloud services revenue increased 43% in the same quarter. AWS remains the larger cloud business and Azure the faster-growing one, but the growth gap has narrowed as AWS reaccelerated.

The next filings will show whether that acceleration keeps closing the gap and how fast both backlogs turn into revenue. For anyone comparing the two platforms, the matched window and the scope label on each figure matter more than any single headline number.
