Microsoft posts best quarter in decades as AI focus strengthens
Azure growth hit a four-year high and pushed Microsoft shares to their best calendar quarter since 1998
Microsoft just had the kind of quarter that makes rival CFOs quietly reread their own slide decks.
Fiscal fourth-quarter 2026 revenue came in at $90 billion, up 18% from a year earlier. Cloud and AI demand did most of the heavy lifting.
Shares rose approximately 37.5% to 39% during calendar Q3 2026. That was the company’s best stretch since 1998, and it added roughly $1 trillion in market capitalization.
The numbers behind the rally
Microsoft reported results on July 29. The next day, the stock jumped 16%, adding approximately $450 billion in market value in a single session.
The star of the show was Azure, Microsoft’s cloud computing platform. Revenue in that division grew 43%, the fastest pace in four years.
Azure also crossed $100 billion in annual revenue for the first time.

The broader Microsoft Cloud segment, which bundles Azure with other cloud products, brought in $59.3 billion. That marks a 27% increase year over year.
Microsoft 365 Copilot passed 30 million paid seats. Each seat is a business paying extra for AI help on top of software it already uses.
Why the AI spending story finally clicked
On the earnings call, Microsoft executives argued that heavy infrastructure investment is producing real returns, pointing to Azure’s growth and its new $100 billion milestone as evidence.
Microsoft generates positive cash flow while it spends on AI, putting it in a different position than competitors relying on borrowed money or investor patience.
What comes next for Microsoft and its rivals
Analysts project Azure growth of around 45% in constant currency for the first quarter of fiscal 2027. Analysts also project continued double-digit growth for Microsoft overall.
The next checkpoint is the company’s earnings report, expected in late October or early November 2026.
The key metrics to watch are straightforward. Can Azure hit the roughly 45% constant-currency growth analysts expect? Does Copilot keep adding paid seats beyond 30 million? And does cash flow stay strong as infrastructure spending continues?
