- Cloud infrastructure revenues jumped by roughly 30% year‑on‑year in Q4 2025, driven by GenAI workloads and AI‑enhanced services.
- Major hyperscalers maintain dominance, but rising AI demand is reshaping competition and regional growth patterns.
What happened
The global cloud infrastructure market experienced a significant surge in the final quarter of 2025, with revenues reaching approximately US $119 billion — about 30% higher than a year earlier, according to Synergy Research Group data. This marked acceleration is widely attributed to demand for generative artificial intelligence (GenAI) services and the integration of AI features across a broader portfolio of cloud offerings.
Synergy’s figures show that GenAI is not only driving incremental spending on new AI‑specific cloud services, such as large‑model hosting and GPU‑accelerated compute, but also enhancing traditional cloud infrastructure services, prompting enterprises to increase their overall cloud outlays.
The so‑called “Big Three” hyperscale cloud providers — Amazon Web Services, Microsoft Azure and Google Cloud — collectively account for around two‑thirds of the market, with AWS retaining the largest share. However, Microsoft and Google have been growing at a faster pace than AWS, reflecting fierce competition among major players to capture AI‑related workloads.
Smaller and specialised cloud providers are also benefiting from this trend. Companies such as CoreWeave, OpenAI’s cloud arrangements, Oracle, Crusoe and Nebius have reported strong growth rates, with some crossing key revenue milestones as AI demand creates space for niche and GPU‑focused service offerings.
Regionally, AI‑driven cloud demand is growing across multiple markets, with robust expansion in Australia, India, Indonesia, Ireland, Mexico, South Africa and Taiwan when measured in local currencies, underscoring how GenAI is not only a US‑centric phenomenon but a global cloud driver.

Why it’s important
The rapid acceleration in cloud spending highlights how GenAI workloads are becoming a central driver of IT infrastructure investment rather than a niche experimental use case. Enterprises increasingly deploy AI‑enabled applications — from advanced analytics to AI‑powered operational tooling — demanding scalable and flexible cloud environments.
This trend is significant for cloud providers and customers alike. For providers, meeting GenAI demand means expanding high‑performance computing capacity, optimising GPU resources and innovating around AI service offerings. For customers, the shift underscores the need to balance cost, performance and governance as AI workloads grow in scale.
However, questions arise about sustainability and market concentration. With a handful of hyperscalers dominating the majority of revenue and infrastructure, smaller players may struggle to compete without specialised offerings. Furthermore, as spending continues to accelerate, organisations must ensure they derive tangible business value rather than simply scaling capacity in response to hype.
The cloud market’s trajectory suggests that GenAI will remain a key structural force in enterprise IT spending and infrastructure planning throughout 2026 and beyond.
