Cloud Infrastructure Spending Reaches $102.6 Billion: TTGT Subsidiary Omdia Reveals Surging Enterprise AI Demand
Global Cloud Infrastructure Market Growth Remains Strong—AI Moves from Experiment to Production
Omdia, a research and advisory group under Informa TechTarget, Inc. (NASDAQ:TTGT), reported that global cloud infrastructure spending soared to $102.6 billion in Q3 2025—a robust 25% increase compared to the prior year. This marks the fifth straight quarter of growth above 20%, a signal that enterprise adoption of AI has crossed from pilot projects to widespread deployment.
The three major hyperscalers—Amazon Web Services, Microsoft Azure, and Google Cloud—continue to set the pace, collectively accounting for 66% of all spending. Their combined annual growth reached 29%, powered by rising order backlogs and new AI platform launches tailored for scaled, real-world applications.
| Vendor | Q3 2025 Market Share | Year-on-Year Growth | Key Developments |
|---|---|---|---|
| AWS | 32% | 20% | AgentCore, Nova 2 models, $200B backlog |
| Microsoft Azure | 22% | 40% | OpenAI renewal, Agent Framework, Malaysia/India data center plans |
| Google Cloud | 11% | 36% | Gemini Enterprise, Vertex AI, $157.7B backlog |
Multi-Model & Agent-Based AI Platforms Take Center Stage
As companies accelerate adoption, the competitive landscape among cloud giants is shifting from raw model performance to platform-wide support for multi-model and agent-driven AI. Enterprises are insisting on flexibility, resilience, and production-grade solutions—a trend hyperscalers are meeting by integrating more proprietary and third-party models into their managed AI platforms.
Notable moves in Q3 2025 include AWS launching new Nova models and AgentCore to strengthen its end-to-end AI stack, while Microsoft’s Agent Framework is already being used by clients like KPMG for advanced audit processes. Google Cloud, meanwhile, continues to expand its Vertex AI Model Garden and ramp up enterprise-centric offerings with the launch of Gemini Enterprise, supporting secure no-code development and robust governance.
TTGT Positioned Strategically Amid Cloud Sector Tailwinds
Omdia’s continued thought leadership highlights TTGT’s strategic role as a key intelligence provider within a rapidly evolving market. With enterprises increasingly treating advanced AI and platform flexibility as production requirements, TTGT’s market research arm is well-positioned to benefit from ongoing digital transformation trends and the growing necessity for data-driven decision making.
Order backlogs at the hyperscalers tell a story of sustained demand: AWS is reporting a $200 billion backlog, Microsoft’s Azure platform is expanding in fast-growing regions, and Google Cloud’s backlog jumped nearly 46% in just three months, from $108.2 billion to $157.7 billion. This resilience underscores both the challenges and opportunities across the cloud landscape, propelled by scalable, real-world AI deployments moving out of R&D and into vital business operations.
Key Takeaway: Cloud Spending Surge Validates AI’s Shift to Production—and TTGT’s Research Edge
With cloud infrastructure spend hitting record levels—buoyed by enterprise-scale AI adoption—market watchers may want to pay attention to how platform-centric innovation is outpacing incremental model upgrades. For investors and industry participants, TTGT’s Omdia unit remains a crucial resource as AI and cloud reshape enterprise technology standards.
As the dust settles on Q3 2025, the message is clear: cloud-driven AI capability is not just an experiment, but is rapidly becoming a baseline for global business—and the demand signals remain robust well into the next cycle.
