Microsoft (MSFT) Built a $100B Azure. Can It Outrun Its Own Spending?

When Microsoft (NASDAQ:MSFT) reports again later this month, one line will draw more attention than the rest: how fast Azure grew. That's a lot of weight for a single business inside a company that also sells Windows, Office, Xbox, and LinkedIn. But Azure has earned the spotlight. Azure is Microsoft's cloud platform. Businesses rent its computing power, storage, and AI tools to run their own apps and models. They pay as they use it, so every new AI workload becomes recurring revenue. In fiscal 2026, Azure's revenue passed $100 billion for the first time, according to CEO Satya Nadella, a milestone that cements Microsoft's standing among the 10 Best Growth Stocks to Buy Now According to Billionaires.
