Global spending on cloud infrastructure services reached $95.3 billion in Q2 2025, up 22% year on year. According to Canalys (part of Omdia), cloud demand increased due to AI consumption, revived legacy migrations, and cloud-native scale-ups. As hyperscalers advance their AI capabilities and applications, more customers are adopting multi-model approaches to meet specific cost and use-case requirements. In Q2 2025, Amazon Web Services (AWS), Microsoft Azure and Google Cloud continue to dominate this market with a 65% combined market share of global cloud infrastructure spending. Collectively, customer spending with these three hyperscalers increased 27% year on year. Microsoft Azure (39% y/y growth) and Google Cloud (34% y/y growth) continue to outgrow market leader AWS (17% y/y growth). When taking AWS share lead into account (bottom chart), in actual dollar terms, AWS’s year-on-year increase outpaced that of both Microsoft and Google Cloud. Hyperscalers are experiencing a significant increase in customer demand, with growth driven by AI-related workloads alongside a rebound in traditional migrations and continued capacity expansion by cloud-native enterprises. Investment in AI infrastructure continues to accelerate. In July, Google lifted its 2025 capital expenditure target from US$75 billion to US$85 billion; earlier, AWS projected total spending for 2025 to exceed US$100 billion, while Microsoft announced plans to invest approximately US$80 billion in infrastructure expansion in the current fiscal year. Yi Zhang of Canalys (part of Omdia) pointed out a key trend that customer demand for AI services is evolving from a primary focus on availability and ease of use to a greater emphasis on flexibility and fit-for-purpose model choice. An increasing number of enterprises are seeking the capability to switch between different AI models based on specific business requirements, enabling them to achieve an optimal balance of performance, cost and application fit. Amid this trend, AWS Bedrock, Azure AI Foundry and Google Vertex AI continue to broaden their portfolios of proprietary and third-party models, spanning the full spectrum of capabilities from high-complexity reasoning to low-latency response, thereby supporting a wider range of industries and workloads. Much like the entire $5.3 trillion tech industry, coopetition has become the norm in the generative AI landscape: vendors compete on model advancement and product capabilities even as they collaborate on compute capacity and model distribution. For example, AWS Bedrock aggregates models such as Anthropic’s Claude and OpenAI’s GPT, while OpenAI has added Google Cloud to its compute network to bolster capacity.
Is Oracle missing???
Great breakdown, Jay McBain! This tightening race with a lot of co-opetition is great for customers - it helps to somewhat balance the concentration of power within this big 3 cloud ecosystems
Impressive insights on the growth of cloud infrastructure services! 🚀 With the rapid advancements in AI and evolving customer demands, it’s fascinating to see how hyperscalers are adapting their strategies. How do you see this trend impacting smaller cloud providers in the coming years? 🤔
This is fantastic Jay McBain. Thanks for sharing. I’m particularly interested to see what the private cloud providers are doing and what the data shows after VMware’s business model shift. We’re seeing and talking to a lot of cloud providers looking at other hypervisors. What’s your take?
Insightful share, Jay McBain. What I see most in the field is how these cloud shifts are changing partner and GTM strategies — it’s no longer just about speed and scale, but about building the right ecosystem around AI-driven workloads. Those who align with hyperscalers and specialized partners will be best positioned to capture the next wave of demand.
Those cloud spending curves are less like lines and more like rocket trajectories—and the launchpad? AI demand, obviously. Azure’s 39% growth in Q2 isn’t just a number—it’s a signal for partners to double down on co-sell plays that use AI-native infrastructure. After all, investments like these turn cloud platforms into the connective tissue of innovation.
Any view on Oracle Cloud?

1moAnother example today of coopetition - Microsoft is set to use Anthropic’s tech for AI features in Office 365 after executives found Claude Sonnet 4 outperformed OpenAI’s GPT-5 in some tasks, according to a report from The Information. Microsoft has said the $30-per-month Copilot add-on already has over 100 million users, and analysts estimate it could be a $1 billion annual business. Microsoft will access Anthropic’s models through Amazon Web Services, and the move will blend Anthropic and OpenAI’s technology in the apps.
