Microsoft Confirms 20M+ Paid Copilot Seats
Microsoft disclosed during its FY2026 Q3 earnings call that Microsoft 365 Copilot has exceeded 20 million paid seats, up from 15 million reported in the previous quarter. This rapid increase of 5 million seats quarter over quarter was highlighted in Microsoft’s official investor materials, positioning Copilot as one of the fastest-scaling enterprise AI products to date.
Industry coverage also reflected this milestone, noting that the growth signals increasing adoption across organizations rather than isolated deployments.
Usage Growth Backs Engagement Claims
Beyond seat count, Microsoft shared internal engagement metrics to support its claim that Copilot is being actively used. According to the company’s earnings call, Copilot queries per user increased nearly 20% quarter over quarter.
Additionally, Microsoft stated that weekly usage has reached levels comparable to Outlook, indicating that Copilot is becoming embedded into routine workflows. These figures, however, are based on Microsoft’s internal data and are not independently verified.
Enterprise Customers Driving Large-Scale Deployments
Microsoft attributed much of this growth to enterprise adoption. The company said the number of customers with more than 50,000 Copilot seats has quadrupled year over year.
It also cited major deployments, including Accenture with over 740,000 seats, while companies such as Bayer, Johnson and Johnson, Mercedes-Benz, and Roche have each committed to more than 90,000 seats.
