Microsoft AI revenue up 120%

Microsoft’s latest quarter made one thing very clear: AI is no longer a side bet inside the company. It is already a huge business. On April 29, Microsoft said its AI business had reached a $37 billion annual revenue run rate, up 123% from a year earlier. Azure kept growing fast, commercial backlog climbed again, and the company spent heavily to keep enough compute online. (microsoft.com) ### What actually jumped? The headline number is the AI run rate. Microsoft did not say “AI revenue for the quarter was X.” It said the AI business is now running at a $37 billion annual pace. That is a way of saying the current revenue base has become large enough that, if sustained, it would equal roughly that amount o(microsoft.com)s enterprise AI demand is still expanding from a very high base.

In Microsoft’s fiscal third quarter, Azure and other cloud services kept driving the Intelligent Cloud business, and Microsoft Cloud revenue rose to $54.5 billion, up 29% year over year. This is the part of the company that tur(microsoft.com)ng enterprise stack. (microsoft.com) ### What is that $627 billion figure? It is Microsoft’s commercial remaining performance obligation — basically, revenue already contracted but not recognized yet. Think of it as a giant future-sales queue.

The odd twist is (microsoft.com)h tells you Microsoft is already sitting on a mountain of committed business. (microsoft.com) ### Why are costs rising with it? Because AI scale is brutally expensive. Microsoft said capital expenditures were $31.9 billion in the quarter, even after a sequential dip tied to normal build timing. It also said gross margin percentage fell partly because of continued investment in AI infrastructure and growing AI product us(microsoft.com)ps, more networking, more power equipment, and more data center capacity.

Microsoft’s latest sustainability materials say the company remains committed to its 2030 environmental goals, but they also show how hard that path is getting as AI and cloud expansion increase energy use and emissions pressure.

Officially, no change has been announced.

But the supply side is getting harder and more expensive. That is why companies keep talking about efficiency —(msn.com)y, “just add more AI” stops being a strategy and starts being a budget problem. (microsoft.com) ### Bottom line? Microsoft just showed that AI can already produce tens of billions in annualized revenue. But it also showed the bill for that growth — in capex, margins, and electricity. The boom is real. So is the infrastructure strain. (microsoft.com)
