Three providers control roughly 68% of global cloud infrastructure in 2026: AWS at ~31%, Azure at ~23–25%, and Google Cloud at ~11–12%, per Synergy Research Group. GCP posted $20.0 billion in Q1 2026 revenue, up 63% year over year, its fastest quarter on record. This post covers current AWS vs Azure vs GCP market share, quarterly revenue from SEC filings, growth rates, and margins.
AWS vs Azure vs GCP Market Share – TL;DR
- AWS holds ~31% of the cloud infrastructure market, Azure ~23–25%, and GCP ~11–12% as of Q1 2026, based on Synergy Research data.
- GCP revenue hit $20.0 billion in Q1 2026, up 63% YoY, the fastest disclosed growth rate of any major provider.
- AWS reported $37.59 billion in Q1 2026, up 28% versus 17% growth a year earlier.
- Azure grew 40% in Q3 FY2026, its third straight quarter above 38%, with FY2025 Azure revenue at $75 billion.
- The global cloud market reached $395–419 billion in 2025 and is forecast to hit $778 billion by 2030, per IDC.
The short version of the AWS vs Azure vs GCP market share picture: AWS leads on share, Azure leads on enterprise momentum, and GCP leads on growth rate. All three accelerated in Q1 2026 as AI infrastructure demand lifted the entire market rather than shifting share between providers.
Who Leads the Cloud Market in 2026?
AWS remains the largest cloud provider at ~31% global share in Q1 2026. Azure sits at ~23–25% and GCP at ~11–12%, according to Synergy Research Group data cross-referenced with Canalys.
The Big Three collectively generate about $268 billion in annual cloud infrastructure revenue. Roughly 75% of enterprises now run multi-cloud setups, and Linux underpins most of that footprint, as the cloud provider Linux usage breakdown shows in detail.
| Provider | Market Share (Q1 2026) | Position |
|---|---|---|
| AWS | ~31% | 1st |
| Microsoft Azure | ~23–25% | 2nd |
| Google Cloud | ~11–12% | 3rd |
| All others | ~32% | — |

Azure’s 23–25% share estimate exceeds a straight revenue calculation ($75 billion / $395 billion = 19%) because Synergy weights IaaS-and-PaaS spend, where Azure is stronger. Both figures are valid; they measure different scopes.
AWS vs Azure vs GCP Market Share by Quarterly Revenue
Amazon, Microsoft, and Alphabet all reported on April 29, 2026, and all three beat analyst estimates. AWS posted $37.59 billion, Microsoft’s Intelligent Cloud segment $34.7 billion, and GCP $20.0 billion for the January–March 2026 quarter.
AWS beat StreetAccount’s $36.64 billion consensus by $950 million and accounted for ~21% of Amazon’s total revenue. Microsoft does not break out Azure revenue, only its growth rate, so the Intelligent Cloud figure includes server products and enterprise services.
| Quarter (Calendar) | AWS | Microsoft Intelligent Cloud | Google Cloud |
|---|---|---|---|
| Q1 2025 | $29.27B (+17%) | $26.8B (Azure +33%) | $12.3B (+28%) |
| Q2 2025 | — | $29.9B (Azure +39%) | $13.6B (+32%) |
| Q3 2025 | — | $30.9B (Azure +40%) | — |
| Q4 2025 | — | $32.9B (Azure +39%) | — |
| Q1 2026 | $37.59B (+28%) | $34.7B (Azure +40%) | $20.0B (+63%) |

The dominant OS running those revenue-generating workloads is Linux, which held 49.2% of global cloud workloads in Q2 2025 according to Linux cloud infrastructure market share data.
How Fast Is Each Cloud Provider Growing?
GCP’s 63% jump in Q1 2026, versus 28% a year earlier, is the sharpest single-quarter acceleration among the three. AWS went from 17% to 28% on the same quarter basis, an 11-point acceleration on a much larger base.
Azure grew 40%, 39%, and 40% across Q1–Q3 of Microsoft’s fiscal 2026, three consecutive quarters above 38%. Growth re-accelerated across all three providers after the 2023–2024 enterprise optimization cycle, driven by AI infrastructure demand.
| Growth Metric | Figure |
|---|---|
| GCP YoY growth, Q1 2026 | +63% (fastest ever disclosed) |
| Azure YoY growth, Q3 FY2026 | +40% |
| AWS YoY growth, Q1 2026 | +28% |
| GCP contracted backlog, Q1 2026 | $460+ billion, nearly doubled QoQ |
| Azure FY2025 annual revenue | $75 billion (+34%) |
| Alphabet Q1 2026 consolidated revenue | $109.9 billion (+22%) |

The $460 billion GCP backlog is the most forward-looking number in the dataset. Sundar Pichai said on the Q1 2026 earnings call that contracted commitments nearly doubled quarter on quarter, spend that takes years to convert to recognized revenue.

How Big Is the Global Cloud Market?
The global cloud infrastructure market reached $395 billion in 2025 per IDC and Synergy Research, or $419 billion under broader estimates that include managed services. IDC forecasts $778 billion by 2030, roughly a doubling.

Distribution choice affects these unit economics too; RHEL and Ubuntu dominate paid enterprise deployments, per the Linux distribution market share breakdown. Regional demand varies as well, with the US and China leading enterprise server spend based on country-level adoption data.
