Cloud market share, Q3 2026

Source: Data Center Knowledge, Nov 3, 2026.

Spending on cloud infrastructure services reached $168 billion in the third quarter of 2026. That was 55% more than in the same quarter of 2025.

A share of 26% of $168 billion works out to $43.7 billion, while AWS reported about $46.0 billion for the same quarter. For Microsoft the same arithmetic gives $31.9 billion against $33.2 billion of Azure revenue, and for Google $26.9 billion against $30.7 billion for a segment that includes Workspace.

The figures differ because they measure different things. The analyst applies one definition of cloud infrastructure services to every provider. Each company draws its own segment boundary. This site ranks on reported revenue and shows share next to it.

The market grew 55% in the third quarter. Measured on their own latest quarter, 4 of the 10 ranked companies grew faster than that and 6 grew more slowly. Quarters differ between companies, so read this as a rough comparison.
