Generative AI Fuels Cloud Market Growth as Revenue Reaches $143 Billion

Generative AI is reshaping enterprise IT spending, driving the strongest growth in cloud infrastructure services since 2018. As organizations race to build AI capabilities and expand computing capacity, cloud platforms have become the foundation of this transformation.

According to new data from Synergy Research, worldwide spending on cloud infrastructure services reached $143.4 billion in the second quarter of 2026, marking a 43% year-over-year increase. This is the fastest growth rate the industry has seen in eight years, and cloud spending has doubled over the past 11 quarters.

A major factor behind this expansion is the rapid adoption of generative AI (GenAI). This research found that AI-related cloud services are growing much faster than the overall market, and AI technologies are also boosting demand across many other cloud-based applications and services.

AWS, Microsoft, and Google continue to dominate the cloud market

Interestingly, Amazon Web Services (AWS) remained the leading cloud provider with a 28% share, followed by Microsoft at 20% and Google at 15%. AWS still holds the largest share, but Microsoft and Google are increasing their revenues rapidly.

This report also highlights the rise of newer AI-focused cloud companies, which are called “neoclouds.” Companies (such as CoreWeave, OpenAI, Oracle, Crusoe, Nebius, Anthropic, and Nscale) are among the fastest-growing providers that reflect the strong demand for AI computing infrastructure.

Public cloud services continue to outpace the market

Public cloud services (like infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS)) accounted for most market revenue and grew even faster than the overall market at 47% year over year. The three largest providers together controlled about 67% of the public cloud sector.

Regionally, cloud adoption continued to expand worldwide. The United States remained the largest cloud market and grew by 49%, which outperformed the global average. Some of the fastest-growing national markets included India, Indonesia, Ireland, Thailand, and Malaysia, while Ireland and several Nordic countries led growth in Europe.

Best practices for maximizing AI and cloud investments

Organizations should treat the current cloud and AI boom as more than a technology trend. Businesses need to analyze whether their existing infrastructure can support advanced analytics, machine learning, and generative AI applications at scale. Companies that modernize their cloud environments, strengthen data management practices, and invest in scalable architectures will be able to take advantage of emerging AI opportunities.

Additionally, organizations should avoid adopting AI and cloud services without a clear business strategy. As cloud consumption increases, business leaders should focus on governance, security, cost optimization, and workforce readiness to ensure investments generate measurable value. They should partner with established cloud providers, develop internal AI skills, and prioritize high-impact use cases to help organizations balance innovation with operational efficiency.
