--- title: "Cloud Market Share Statistics 2026: Largest Cloud Providers Ranked" date: 2026-11-12 author: "Brad Nickel" featured_image: "https://tricitylocalnews.com/wp-content/uploads/2026/10/cloud-market-share-largest-cloud-providers-ranked.jpg" categories: - name: "Cloud" url: "/cloud.md" tags: - name: "Statistics" url: "/tag/statistics.md" --- # Cloud Market Share Statistics 2026: Largest Cloud Providers Ranked Amazon Web Services (AWS) remained the leader in the global cloud infrastructure market in Q4 2025, with a **32%** market share, according to Omdia. Microsoft Azure held a **22%** market share and Google Cloud **12%**. Global spending on cloud infrastructure services reached **$110.9 billion** in Q4 2025, reflecting year-over-year growth of **29%**. Gartner’s count of infrastructure as a service (IaaS) alone gave Amazon **37.7%** market share in 2024, so the share each of the cloud providers holds depends on what is counted. Company filings carry the picture into 2026. In the June 2026 quarter, Google Cloud revenues increased **82%** to **$24.8 billion**, while AWS segment sales increased **37%** year-over-year to **$42.2 billion**. In its quarter ended August 31, 2026, Oracle’s Cloud Infra (IaaS) revenue was up **121%** in USD to **$7.4 billion**. The smaller providers are growing faster, while the order at the top has held. ## Key Takeaways - Google Cloud’s market share went from **11%** in Q3 2025 to **12%** in Q4 2025, while AWS held a **32%** market share and Microsoft Azure **22%** in both quarters. - In 2024, the top five IaaS providers accounted for **82.1%** of the market, by Gartner’s count. - Oracle’s cloud infrastructure revenue grew **3.3 times** as fast as AWS segment sales in each company’s latest quarter (**121%** against **37%**). - Google Cloud’s operating income equaled **35.6%** of its segment revenue in Q2 2026. - Omdia forecasts that global cloud infrastructure services spending will grow by **27%** in 2026. - Gartner forecasts AI-optimized IaaS spending of **$42,276 million** in 2026, growth of **96.4%**. ## Editor’s Choice - AWS annualized revenue run rate: **$169 billion**, as of the quarter ended June 30, 2026. - Azure revenue, Microsoft fiscal 2026: surpassed **$100 billion** for the first time. - Microsoft Cloud revenue, quarter ended June 30, 2026: **$59.3 billion**, an increase of **27%**. - Worldwide IaaS spending, 2026 Gartner forecast: **$287,347 million** in total IaaS spending. - Microsoft commercial remaining performance obligation (RPO): **$678 billion**, up **84%**. - Google Cloud backlog, Q1 2026: over **$460 billion**, nearly doubling quarter-on-quarter. ## Cloud Market Share by Provider - AWS remained the leader in the global cloud infrastructure market in Q4 2025, with a **32%** market share and **24%** year-over-year revenue growth, Omdia estimates. - Microsoft Azure remained the world’s second-largest cloud service provider in Q4 2025, with a **22%** market share and year-over-year revenue growth of **39%**. - Google Cloud held its position as the world’s third-largest cloud service provider in Q4 2025, delivering year-over-year growth of **50%** and expanding its market share to **12%**. - In Q3 2025, AWS, Microsoft Azure, and Google Cloud collectively accounted for **66%** of global cloud infrastructure spending, and their Q4 2025 shares again add up to **66%**.

On Gartner’s IaaS table for 2024, Amazon held **37.7%** market share and Microsoft **23.9%**. ## Google Cloud Market Share and Revenue - In Q2 2026, Google Cloud revenue was **$24,768 million**, up from **$13,624 million** a year earlier. - Growth was led by an increase in Google Cloud Platform (GCP) across enterprise AI Solutions and enterprise AI Infrastructure, as well as core GCP services, Alphabet said. - Google Cloud delivered **36%** year-over-year growth in Q3 2025 and increased its market share to **11%**, Omdia said, adding that growth was primarily driven by enterprise AI offerings. 2025 vs 2026 · Source: Alphabet (first- and second-quarter 2026 results) Alphabet · 2026 Google Cloud Revenue, Q1 and Q2 ($ millions) 2025 vs 2026 2025 revenue 2026 revenue 25,000 20,000 15,000 10,000 5,000 0 $12,260M $20,028M $13,624M $24,768M Q1 Q2 2025 revenue · $12,260M 2026 revenue · $20,028M 2025 revenue · $13,624M 2026 revenue · $24,768M SOURCE Alphabet (first- and second-quarter 2026 results) View the data| Quarter | 2025 revenue ($ millions) | 2026 revenue ($ millions) | |---|---|---| | Q1 | 12,260 | 20,028 | | Q2 | 13,624 | 24,768 | > **Worth noting:** Google Cloud includes infrastructure and platform services, applications, and other products and services for enterprise customers, including Google Workspace communication and collaboration tools. Alphabet’s segment revenue is therefore wider than the infrastructure services Omdia counts, so its growth rate and Omdia’s share measure different things. ## Cloud Provider Operating Income - In Q2 2026, Google Cloud operating income was **$8,814 million**, against **$2,826 million** a year earlier, **3.1 times** the prior-year figure. - Google Cloud’s operating income equaled **35.6%** of its **$24,768 million** in segment revenue in Q2 2026. - AWS segment operating income was **$16,621 million** in Q2 2026, equal to **39.4%** of AWS net sales. - At Microsoft, Intelligent Cloud’s operating income equaled **40.6%** of segment revenue in the quarter ended June 30, 2026. - In Q1 2026, Google Cloud operating income was **$6,598 million**, against **$2,177 million** a year earlier. - At CoreWeave, the operating loss was **$49 million** for the three months ended June 30, 2026, against operating income of **$19 million** in 2025.

Scope and period explain most of that gap, so each share needs its definition beside it. ### Why do cloud market share figures differ between analysts? Analysts count different services over different periods. Omdia’s cloud infrastructure services total adds bare metal, platform, container, and serverless services to IaaS, while Gartner’s table measures the worldwide IaaS public cloud services market. Company segments differ again, since Google Cloud includes Workspace and Alibaba’s segment now includes T-Head chips. ## Conclusion AWS remained the leader with a **32%** market share in Q4 2025, ahead of Microsoft Azure at **22%** and Google Cloud at **12%**, by Omdia’s count. Company filings since then show the challengers growing faster: Google Cloud revenues increased **82%** in Alphabet’s second quarter, against AWS segment sales growth of **37%**. Share, growth, profit and backlog rank the cloud providers a little differently, so the scope and period behind each figure matter as much as the figure itself. Omdia forecasts that global cloud infrastructure services spending will grow by **27%** in 2026, and Gartner forecasts total IaaS spending of **$287,347 million** in 2026. With most spending on three platforms, how often those platforms fail matters to most buyers, and the record of major cloud outages tracks it.
