Cloud infrastructure spending Q2 2026 exceeded $143 billion, up 43% from a year earlier, according to Synergy Research. The research firm said that was the fastest growth rate for the market in eight years, a signal that AI-related compute demand is still turning into revenue for the largest cloud providers.
Synergy said the market has now doubled over a period that included 11 straight quarters of accelerating growth. For the trailing 12 months, total cloud infrastructure service revenue reached $500 billion, according to the firm.
Public infrastructure-as-a-service and platform-as-a-service products made up most of the market and grew 47% in the quarter, Synergy said. Those categories cover the rented compute, storage, networking and developer platform services that enterprises use instead of buying and operating more of their own infrastructure.
What is driving cloud infrastructure spending in Q2 2026?
Synergy attributed the extra acceleration mainly to AI services, alongside continued enterprise demand for flexible and scalable IT capacity. John Dinsdale, Synergy’s chief analyst, said AI accounted for most of the incremental growth and that AI-specific cloud services are now growing 165% year over year.
That AI figure is a rate, not a disclosed dollar amount in the figures cited. It still points to where cloud providers are getting the next leg of demand: training and inference capacity, GPU availability and managed AI services. Synergy said the main beneficiaries are a small group of leading cloud platforms and neoclouds, the specialized operators renting access to GPU-heavy infrastructure.
The same concentration remains clear at the top of the market. Synergy said Amazon Web Services, Microsoft Azure and Google Cloud accounted for 67% of global cloud revenue in the quarter, up from 63% in the third quarter of last year. The individual market share figures cited were 28% for AWS, 20% for Microsoft and 15% for Google.
AWS remains the largest provider by share, but Microsoft is close enough that the gap is no longer a static feature of the market. Google remains third globally. The concentration matters for enterprise buyers and infrastructure startups because AI demand is reinforcing the advantage of companies that can fund data centers, power agreements, networking and accelerator supply at global scale.
Among second-tier providers, Synergy named CoreWeave, Oracle, Crusoe, Nebius and Nscale as companies with some of the highest growth rates. Oracle held 4% of the market, while CoreWeave had 2%, according to the firm. Providers at roughly 1% share included IBM, Akamai, Baidu, China Mobile, China Telecom, China Unicom, Snowflake, Tencent and SAP.
Synergy also said nine rent-a-GPU neocloud operators now rank among the top 40 cloud providers by service revenue. That is a notable sign that AI infrastructure demand is large enough to support specialist suppliers, although the top three cloud platforms still capture most spending.
The United States remained the largest cloud market and widened its lead, growing 49% in the quarter, above the global average. Synergy said other countries growing faster than the worldwide market included India, Indonesia, Ireland, Thailand and Malaysia. In Europe, the largest cloud markets were the United Kingdom and Germany, while Ireland, Norway, Denmark and Finland grew the fastest.
