# Public Cloud Provider Comparison: AWS, Azure, GCP, OCI, DigitalOcean & More > Source: > Published: 2026-06-02 00:00:00+00:00 The global cloud infrastructure services market reached approximately **$395 billion in 2025**, representing a 17% year-over-year expansion and is projected to exceed $500 billion by mid-2026, driven primarily by generative AI workloads. [1,2] The competitive landscape remains dominated by three hyperscalers—Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP)—which collectively control approximately **63% of total enterprise cloud spending** as of Q1 2026. However, the competitive dynamics are shifting: AWS’s market share has narrowed from about 30% to 28% year-over-year, while GCP surged 63% YoY and Oracle Cloud Infrastructure (OCI) grew 44%, signaling intensifying competition beyond the traditional top two.
