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.

How big is the cloud infrastructure market?

Global spending on cloud infrastructure services reached $110.9 billion in Q4 2025, according to Omdia. Gartner puts total IaaS spending at $222,170 million in 2025. Gartner counts IaaS alone, while Omdia adds bare metal, platform, container, and serverless services, so the two totals differ and should be read separately.

IaaS Market Share by Vendor

• Amazon continued to lead the worldwide IaaS market with revenue of $64.8 billion and 37.7% market share, followed by Microsoft with 23.9% market share in 2024.
• Amazon’s share was 39.0% in 2023, a drop of 1.3 points in a year.
• Google’s IaaS revenue grew 35.4% from 2023 to 2024, reaching $15,519.5 million.
• Alibaba Group’s IaaS revenue grew 11.8% to $12,444.9 million over the same period.
• Gartner rounds each share to one decimal, so the five leaders’ 2024 shares in the chart below add to 81.9%, not 82.1%, and each year’s shares sum to 99.8% (2024) and 100.1% (2023) rather than exactly 100%.

Who are the big 5 cloud providers?

Amazon retained the No. 1 position in the IaaS market in 2024, followed by Microsoft, Google, Alibaba and Huawei, according to Gartner. Together, the top five IaaS providers accounted for 82.1% of the market, with others at 17.9%.

AWS Market Share and Revenue

• In the quarter ended June 30, 2026, AWS net sales rose by $11,359 million ($11.4 billion) year-over-year to $42,232 million ($42.2 billion), the largest dollar gain of the three segments in the chart below.
• AWS grew 36.7% year-over-year in Q2, its fastest growth in 18 quarters, Amazon said in its second-quarter 2026 results.
• AWS had a 32% share and 20% year-over-year revenue growth in Q3 2025, supported by easing compute supply constraints and demand driven by its partnership with Anthropic, according to Omdia.
• In Q1 2026, AWS segment operating income was $14.2 billion, compared with $11.5 billion in the first quarter of 2025.

By the numbers: AWS net sales increased 37% to a $169 billion annualized revenue run rate, Amazon reported for its second quarter. The AI and Chips businesses each eclipsed run rates of more than $25 billion. Microsoft’s quarters in the chart are its fiscal fourth quarters, which cover the same April to June months.

Microsoft Azure Market Share and Growth

• Azure revenue surpassed $100 billion for the first time in Microsoft’s fiscal year ended June 30, 2026.
• Azure and other cloud services revenue increased 43% in the quarter ended June 30, 2026.

What is the market share of AWS compared to Azure?

AWS held a 32% market share in Q4 2025, and Microsoft Azure held 22%, according to Omdia’s count of cloud infrastructure services, a gap of 10 points. 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.

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.

Cloud Backlog and Remaining Performance Obligations

• Oracle booked more than $30 billion of additional AI cloud contracts in Q1 of fiscal 2027.
• AWS ended Q4 2025 with a total backlog of $244 billion, up from a total backlog of $200 billion by the end of Q3.
• As of September 30, 2025, Google Cloud reported a backlog of $157.7 billion, up sharply from $108.2 billion in Q2 of 2025.
• RPO and backlog are company-defined measures, and Microsoft’s figure covers its whole commercial business, not Azure alone.

Source: Microsoft, Oracle, Alphabet, Omdia

Key finding: Microsoft’s commercial remaining performance obligation increased 84% to $678 billion, while Microsoft Cloud revenue was $59.3 billion and increased 27%. Contracted commitments grew 3.1 times as fast as Microsoft Cloud revenue. Revenue that is already signed for points to growth that has not yet reached the income statement.

Oracle and Alibaba Cloud Market Share

• Oracle’s Total Cloud Revenues were up 62% in USD and up 61% in constant currency to $11.6 billion in its first quarter of fiscal 2027.
• In Oracle’s software as a service (SaaS) business, Cloud Apps (SaaS) revenue was up 10% in USD and constant currency to $4.2 billion.
• AI Cloud and Compute Services combines Cloud Intelligence Group with T-Head, so Alibaba’s newest cloud figures do not line up with its earlier Cloud Intelligence Group series.
• AI-related product revenue achieved RMB 12,376 million ($1,824 million), the twelfth consecutive quarter of triple-digit year-over-year growth, Alibaba said.
• Alibaba Group says that, in an Omdia report on China’s AI cloud market for 2025, Alibaba Cloud ranked first in China’s AI cloud market with the largest share of 38.1%.
• Alibaba Group held 7.2% market share of worldwide IaaS in 2024, by Gartner’s count.

Neocloud Providers and AI-Optimized IaaS

• CoreWeave’s revenue grew 112% year-over-year, from $1,212 million to $2,575 million.
• CoreWeave, an AI cloud provider that rents out GPU capacity, measures capacity in megawatts (MW) and gigawatts (GW) of power. It expanded active power by nearly 500 MWs to reach 1.5 GW and grew total contracted power to approximately 3.7 GW.
• Gartner forecasts AI-optimized IaaS spending of $42,276 million in 2026, growth of 96.4%, and $66,143 million in 2027.
• The share of AI-optimized IaaS spending that supports inference is set to reach 59% in 2027, Gartner forecasts.

How Analysts Measure Cloud Market Share

• Omdia defines cloud infrastructure services as the sum of bare metal as a service (BMaaS), infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), container-as-a-service (CaaS), and serverless that are hosted by third-party providers.
• Gartner’s measure is the worldwide infrastructure as a service (IaaS) market, which grew 22.5% in 2024, reaching $171.8 billion.
• Google Cloud generates services revenue primarily from consumption-based fees and subscriptions, Alphabet says.

Source: Omdia, Gartner, Amazon, Alphabet, Microsoft, Alibaba Group

Why it matters: Omdia put AWS at a 32% market share in Q4 2025, while Gartner’s IaaS table gave Amazon 37.7% market share in 2024. 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.
