Cloud spending surges as AI drives growth in Q3 2025

Cloud spending surges as AI drives growth in Q3 2025 is profiled by BTW Media because public-source evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• Global cloud infrastructure spending reached $102.6 billion in Q3 2025, up 25 per cent year-on-year, marking the fifth consecutive quarter of strong growth. 
• Hyperscalers AWS, Microsoft Azure and Google Cloud accounted for 66 per cent of the total, shifting competition towards platform-level AI capabilities. 

What happened: Cloud infrastructure spending accelerates as enterprises scale AI workloads

Research from analyst group Omdia shows that global expenditure on cloud infrastructure services hit $102.6 billion in the third quarter of 2025, a rise of 25 per cent compared with the same period last year, continuing a trend of robust expansion above 20 per cent for the fifth quarter in a row. 

Omdia’s report links this sustained growth to enterprises shifting from early experimentation with artificial intelligence towards scaled production-ready deployments. The report observes that demand for cloud infrastructure is increasingly driven by applications that require multi-model strategies and agent-based AI systems rather than simply the performance of individual models. 

The big three hyperscale cloud platforms — Amazon Web Services (AWS), Microsoft Azure and Google Cloud — maintained their ranking from the previous quarter and collectively captured 66 per cent of total cloud infrastructure spend. Together they delivered around 29 per cent year-on-year revenue growth. 

According to industry data beyond the initial report, AWS re-accelerated its growth to about 20 per cent year-on-year, its strongest pace since 2022, while Microsoft Azure and Google Cloud each clocked growth of more than 35 per cent — evidence of rapidly expanding enterprise demand for cloud-based AI and data services.

Why it’s important

This surge in cloud infrastructure spending has broader implications for the technology sector. As organisations increasingly commit to large-scale cloud adoption, cloud providers are moving from offering experimental tools to delivering production-ready platforms that support complex, real-world applications — especially those involving AI. 

The dominance of AWS, Azure and Google Cloud underscores how concentrated this market remains. Their combined market share of two-thirds suggests that while competition from smaller cloud providers and regional players exists, the hyperscale trio continues to shape the pace and direction of cloud innovation. 

Growth in cloud spending also ties closely to broader digital transformation trends. According to other market analyses, public cloud services are expected to account for a majority of enterprise IT spending soon, reflecting a structural shift away from on-premises infrastructure. 

At the same time, organisations are balancing increased cloud investment with cost control and risk management strategies, particularly as public cloud environments become more complex. For policymakers and business leaders alike, understanding how these spending trends interact with issues such as data sovereignty, cybersecurity and competitive dynamics will be critical as the cloud market continues to evolve.
