Microsoft stocks fell more than 2.5% toward $520 after touching near $560 last week. The drop came as investors reassessed how much of the company’s cloud buildout will be paid for by Microsoft itself and how much pressure Anthropic may put on its workplace-software business.
That slide came after Microsoft had just posted a quarter with $90.6 billion in revenue, $36.6 billion in net income and $4.92 per diluted share on a GAAP basis. The contrast is stark: the company is still delivering large profits, but shareholders are now pricing in the cost of keeping Azure supplied with enough capacity to support expanding workloads.
Noelle Walsh on data-centre costs
Noelle Walsh, Microsoft’s President of Cloud Operations and Innovation, said the company would pay for its own data-centre construction and associated infrastructure. She oversees approximately 15,000 employees across Microsoft’s global data-centre operations, a scale that shows how central the buildout has become to Azure and Microsoft 365 Cloud.
Microsoft has also pledged to cover electricity costs and grid infrastructure upgrades tied to its projects rather than push those expenses onto local residents. For investors, that means the capital burden sits inside Microsoft’s own margins and cash flow, not on the communities around the projects.
Anthropic pushes into workplace software
Anthropic introduced a new suite of workplace software aimed at markets dominated by Microsoft and Google. The lineup includes a videoconferencing assistant, data dashboards and Claude Sheets, with several tools reportedly in beta for paying customers.
Anthropic also plans to let enterprises integrate existing applications into Claude. That moves the competition beyond chat into daily work tasks, where Microsoft’s productivity software and Azure-linked services have long been the default choice for large organizations.
Microsoft 365 Cloud still drives growth
Microsoft 365 Cloud generated $27.78 billion in revenue in the first quarter of fiscal 2027 ended September 30, 2026. That was about 17% year-over-year growth and roughly 30% of total company revenue, even before the full effect of the latest stock move.
Microsoft’s latest quarter also beat expectations, with earnings of $4.89 per share on a non-GAAP basis excluding the impact of investments in OpenAI, versus analyst consensus of $4.27 per share. The market’s pullback suggests investors are no longer focusing only on earnings delivery; they are weighing whether the returns from Microsoft’s infrastructure spending will justify the heavier bill attached to Azure and the rest of the cloud stack.
