As global cloud infrastructure spending soared to US$102.6 billion in Q3 — up 25 percent year-on-year — AWS, Microsoft Azure and Google Cloud solidified their leadership by snaring 66 percent of the market, according to Omdia.
This fifth straight quarter of more than 20 percent growth was fuelled by enterprises scaling AI from pilots to production, driving hyperscalers to emphasise multi-model platforms and AI agents.
AWS held the top spot with 32 percent market share and 20 percent year-on-year revenue growth bolstered by easing compute constraints, Anthropic ties, and a US$200 billion backlog.
Microsoft Azure was next with 22 percent share on 40 percent growth, powered by its OpenAI renewal, Azure AI Foundry serving 80,000 customers across 11,000 models, and new Agent Framework tools.
Google Cloud came in third with 11 percent share and 36 percent growth on a backlog jump to US$157.7 billion and Vertex AI expansions including Gemini 2.5 models.
“Collaboration across the ecosystem remains critical. Multi-model support is increasingly viewed as a production requirement rather than a feature, as enterprises seek resilience, cost control, and deployment flexibility across generative AI workloads,” said Rachel Brindley, Senior Director of Omdia.
