Summary

  • Microsoft Cloud revenue reached $63.9 billion, up 30%; Azure revenue increased 48%.
  • Microsoft Cloud gross-margin percentage fell to 66% as Azure took a larger share of the sales mix. The filing also records rising data-centre and compute-capacity costs.

Analysis

The cloud growth line is moving up. The margin line is moving down.

Microsoft reported $63.9 billion in Microsoft Cloud revenue for the three months ended 30 September 2026, against $49.1 billion a year earlier. The company defines Microsoft Cloud as Azure, Microsoft 365 commercial cloud and Industry solutions cloud. Azure supplied the fastest growth: revenue rose $10.8 billion, or 48%, on demand for services across its platform.

The combined Microsoft Cloud gross-margin percentage fell to 66%. Microsoft attributes the change to a larger Azure share of sales. Product-level margin improvements, primarily in Azure, partly offset the decline.

The physical bill is visible elsewhere in the same filing. Cost of revenue in the Agents and Infra segment rose $6.2 billion, or 35%, as Microsoft invested in data-centre infrastructure for demand across Azure and Microsoft 365 cloud. Company-wide operating expenses increased $975 million, or 6%, with continued R&D investment in compute capacity and talent.

Total revenue still grew 19% to $92.3 billion and operating income rose 21% to $45.9 billion. Cloud margin compression is occurring alongside that company-wide expansion. The test is what each additional dollar of cloud capacity earns as the sales mix changes.

Microsoft does not publish Azure gross-profit dollars or a margin schedule by cloud workload. The filing also says segment assets are not allocated for internal reporting. Those figures would show whether Azure’s faster growth is adding enough gross profit dollars to offset the lower blended percentage.
