Microsoft Reports 20M Paid Copilot Users with Strong Usage
Microsoft countered doubts about Copilot adoption by announcing robust growth in users and activity for its AI assistant integrated into Microsoft 365 applications such as Word, Excel, and Outlook.
During the company's quarterly earnings conference call, CEO Satya Nadella stated that Microsoft 365 Copilot holds 20 million paid enterprise seats. This figure highlights significant enterprise uptake for the tool, which assists with tasks inside productivity software from Microsoft, a firm founded in 1975 and known for its dominant position in office software worldwide.
Enterprise Adoption Accelerates
Nadella pointed out that the number of companies subscribing to more than 50,000 seats has increased fourfold. Major organizations like Bayer, a global pharmaceutical and life sciences company, Johnson & Johnson, a healthcare giant, Mercedes, the automotive manufacturer, and Roche, another pharmaceutical leader, each maintain over 90,000 seats.
He highlighted a recent agreement with Accenture, a leading professional services firm, for more than 740,000 seats. Nadella called this Microsoft's biggest Copilot deal so far.
Usage Matches Email Habits
Nadella stressed actual usage, saying Copilot queries per user climbed nearly 20% from the previous quarter. Weekly engagement now equals that of Outlook, Microsoft's email client used by millions daily in businesses.
"This is like a daily habit of intense usage," he added.

Morgan Stanley analyst Keith Weiss commented during the call that these Microsoft 365 Copilot figures stand out as very strong and surpass what most observers anticipated.
Flexible Model Integration
Copilot does not rely on a single AI model, such as those from OpenAI. Users can access several models through chat by default. Features include smart routing in agents, critique options, and combining models for better responses.
For example, Microsoft 365 integrates Anthropic's Claude model. This multi-model approach allows Copilot to draw from various AI providers, enhancing reliability and performance across different tasks.
Agent Mode Drives New Habits
One key factor behind rising usage is agent mode. As of last week, it became the default setting in Copilot, Word, Excel, and PowerPoint. Microsoft made these agentic features generally available recently.
Agent mode enables Copilot to handle multi-step actions right within documents. "You now have a new way to delegate and complete work using Copilot," Nadella explained.
This capability shifts how workers interact with AI, turning it into a proactive assistant rather than just a responder. Microsoft 365 Copilot, launched to enterprise customers in late 2023 after preview periods, builds on Microsoft's investments in AI to boost productivity in its core apps, which serve over 345 million paid seats globally.
The earnings call details reflect Microsoft's focus on proving Copilot's value amid competition from other AI tools. Companies like Accenture, with its vast consulting workforce, adopt it at scale to streamline operations. Similarly, firms in pharma and auto sectors use it for data analysis and document handling.
