Microsoft Cloud revenue hits $63.9 billion on AI agent growth

Cloud growth and AI adoption

Microsoft reported that its cloud revenue reached $63.9 billion for the three months ended September 30, 2026. This figure represents a 30 percent increase compared to the same period last year. The growth was primarily fueled by rising demand for Copilot, AI development tools, and the underlying infrastructure required to run them.

The company's total quarterly revenue also saw a significant climb, reaching $92.3 billion. Within that total, revenue from Azure, Microsoft's primary cloud computing platform, increased by 48 percent. These numbers suggest that enterprise customers are rapidly integrating AI into their core computing environments.

Microsoft's net income reached $36.6 billion, which was a 32 percent increase from the previous year. When adjusting for the impact of the company's investments in OpenAI, the adjusted net income rose 18 percent to $36.4 billion. These figures highlight the scale of the company's financial performance during this period of heavy AI investment.

The expansion of Copilot

Usage of Copilot has seen a dramatic spike, with daily users increasing nearly 50 percent from the previous quarter. When compared to a year ago, the number of daily users has grown more than fivefold. Additionally, the number of customers with more than 50,000 licensed Copilot seats increased eightfold over the previous year.

The company is currently consolidating several tools into a single experience. This update includes Chat, Cowork, Autopilot, and Code, which provide a mix of conversational assistance, delegated tasks, automated work, and software creation. By bringing these together, Microsoft aims to provide a more unified interface for different types of AI interactions.

CEO Satya Nadella noted that the company is bringing capabilities from Dynamics 365, a suite of business applications, directly into Copilot. This move is intended to let employees access complex business processes through a single assistant. The goal is to move beyond simple document drafting to help organizations build what Nadella called an 'infinite SaaS factory.'

A shift toward AI agents

A major trend in the latest report is the move toward AI agents, which are systems capable of performing delegated tasks. More than 50 million agents were registered in Agent 365, a management platform that saw a 30 percent increase in registrations quarter over quarter. This indicates that businesses are beginning to manage large fleets of autonomous AI entities.

To support this, Microsoft is linking Windows and Agent 365 through Microsoft Execution Containers, or MXC. This technology provides a controlled environment for agents to operate on devices safely. Notable agents adopting this technology include OpenAI Codex, Anthropic Claude Code, and Meta Muse.

Security is a primary focus for these agents, as the company uses Perception security tools to manage identities and permissions. These tools operate outside the AI model itself to monitor what actions an agent is authorized to take. This approach allows organizations to set firm boundaries on what an autonomous agent can do without relying solely on the model's internal logic.

Infrastructure and Foundry growth

The demand for AI infrastructure is creating a massive need for computing capacity. Microsoft's quarterly capital expenditure reached $45.2 billion as it continues to invest in the hardware needed to support its services. The company is currently adding capacity while also trying to maximize the efficiency of the infrastructure it already owns.

Revenue from Foundry, the platform used for building and running AI applications, more than tripled compared to a year ago. This growth is supported by a fivefold increase in customers building with multiple AI models. Furthermore, revenue from open source models grew tenfold, showing that customers are moving away from relying on a single provider.

Microsoft is also integrating Foundry more closely with Fabric, its data and analytics platform. This allows customers to build agents alongside the specific organizational information they need to use. Nearly 60,000 customers are already accessing context through Microsoft IQ, which helps AI systems work with relevant business data.

Future costs and performance

Looking ahead, Microsoft expects total revenue to fall between $96 billion and $97.1 billion for the next quarter. The company forecasts that Azure revenue growth will be between 49 and 50 percent, excluding currency movements. This forecast suggests that customer demand for cloud and AI infrastructure continues to exceed the current available supply.

The company is prioritizing cost and performance as it enters the next phase of AI adoption. Satya Nadella stated that the next goal is maximizing intelligence per task while optimizing for costs. This focus is intended to make AI more sustainable and affordable for large-scale enterprise use.

For developers, the company is highlighting tools like GitHub Copilot Fusion. This tool coordinates multiple AI models to help produce software. Nadella noted that this approach can deliver high-quality results at up to 77% lower cost. These developments suggest a move toward more efficient, multi-model workflows for software engineering and other complex tasks.
