The cloud giants are riding an AI tidal wave. Amazon and Microsoft posted blowout growth in their cloud divisions as demand for AI infrastructure surges, with AWS revenue up 28% and Microsoft’s Azure up 40%. The results underscore how the AI boom is fueling the cloud business — and triggering a record wave of capital spending as the giants race to build capacity.
AWS reaccelerates
Amazon’s cloud engine is humming. AWS recorded 28% revenue growth in the first quarter, beating estimates, as customers piled into AI services. Spending on Bedrock, its platform for building AI agents and applications, jumped 170% from the prior quarter — consuming more tokens in a single quarter than in its entire history.
Azure powers ahead
Microsoft is right behind. Azure and other cloud services grew 40%, topping analyst estimates and reaffirming Microsoft’s strength as the second-largest cloud provider. The robust growth reflects surging enterprise demand for AI capabilities delivered through the cloud, a core pillar of Microsoft’s strategy.
The capex explosion
Spending is staggering. Capital expenditures have ballooned nearly fourfold, from about $53 billion in fiscal 2023 to close to $200 billion in fiscal 2026, as the giants build data centers and buy chips. The scale of investment reflects conviction that AI demand will keep climbing for years.
AI demand is real
The growth is grounded in usage. The surge in cloud revenue and token consumption shows enterprises moving AI from experiments into production, paying for compute at scale. That tangible, growing demand is what distinguishes this boom from pure speculation — and what justifies the massive buildout.
Custom silicon rises
The giants are building their own chips. Alongside buying from Nvidia, cloud providers are increasingly deploying custom silicon to power AI workloads more efficiently. The push reflects a drive to control costs and capacity as AI compute becomes the central battleground of the cloud wars.
Why it matters
The cloud is the engine of the AI economy. Blowout growth at AWS and Azure signals that AI demand is translating into real revenue, while the capex surge shapes the entire tech supply chain. The health of the cloud giants is a key barometer for whether the AI boom is sustainable.
The bottom line
Amazon and Microsoft rode the AI boom to blowout cloud growth, with AWS up 28% and Azure up 40%, while capital spending surged toward $200 billion. The results show AI demand is real and accelerating, fueling a historic infrastructure buildout. The cloud giants are betting big — and, for now, the bet is paying off.
