Microsoft says it has over 20M paid Copilot users, and they really are using it

Copilot Adoption Numbers

Microsoft CEO Satya Nadella announced significant growth in M365 Copilot adoption during the company's quarterly earnings call:

20 million paid enterprise Copilot seats across M365 apps (Word, Excel, Outlook)
4x growth in companies paying for over 50,000 seats
Major enterprise deployments: Bayer, Johnson & Johnson, Mercedes, and Roche (each 90,000+ seats)
Largest deal to date: Accenture with over 740,000 seats

Engagement Metrics

"Copilot queries per user were up nearly 20% quarter over quarter. To put this momentum in perspective, weekly engagement is now at the same level as Outlook. This is like a daily habit of intense usage." - Satya Nadella

Key Technical Features

Multi-Model Architecture

Model agnostic: Not dependent on any single model (e.g., OpenAI)
Intelligent auto-routing in agents with "critique and counsel"
Multiple models working together to generate optimal responses
Support for Anthropic's Claude alongside other models

Agentic Capabilities (General Availability)

As of last week, Microsoft made Copilot's agentic capabilities generally available:

Agent mode is now the default experience across Copilot in Word, Excel, and PowerPoint
Multi-step actions directly within documents
New capability to delegate and complete work using Copilot
Users can now work with AI that takes autonomous actions rather than just responding to prompts

Market Reception

Morgan Stanley analyst Keith Weiss commented: "Those Microsoft 365 Copilot numbers are super impressive and I think way ahead of most people's expectations."

This counters the lingering perception that Copilot adoption has been slow or that users aren't actually engaging with the tool.
