Microsoft says adoption of its AI assistant Microsoft 365 Copilot is growing rapidly, pushing back against the perception that the tool isn’t widely used.
CEO Satya Nadella revealed during the company’s latest earnings call that Microsoft 365 Copilot has now reached 20 million paid enterprise seats. He also noted a sharp rise in large-scale deployments, with the number of companies purchasing more than 50,000 seats increasing fourfold.
Major enterprises, including Bayer, Johnson & Johnson, Mercedes-Benz, and Roche each have over 90,000 Copilot seats. Microsoft also recently secured its biggest deal yet with Accenture, covering more than 740,000 seats.
Nadella emphasized that engagement is rising alongside adoption. Copilot queries per user increased nearly 20% quarter over quarter, and weekly usage is now comparable to Microsoft Outlook. He described this level of interaction as becoming a daily habit for many users.
Microsoft also highlighted Copilot’s flexibility, noting that it is not tied to a single AI model. Instead, it can access multiple models with intelligent routing to generate better responses. For example, Microsoft 365 supports models like Claude.
Industry analysts are also taking notice. Keith Weiss said the Copilot numbers are ahead of expectations, reflecting stronger-than-anticipated enterprise demand.
A key driver of this growth is the rollout of “agent mode,” which is now the default experience across Copilot in apps like Word, Excel, and PowerPoint. This feature allows the AI to take multi-step actions directly within documents, enabling users to delegate tasks and automate workflows more effectively.

Microsoft says these agentic capabilities are now generally available, marking a shift toward more autonomous AI tools that can actively assist with completing work rather than just responding to prompts.
