Microsoft M365 Copilot surpasses 20 million paid enterprise seats amid surging engagement
Major clients including Accenture and Bayer drive growth as the tool integrates multi-step agent capabilities and multiple AI models.

Microsoft CEO Satya Nadella confirmed during the company's quarterly earnings call that the M365 Copilot platform has surpassed 20 million paid enterprise seats. This announcement marks a significant shift in market perception regarding artificial intelligence adoption, supported by robust engagement metrics where weekly usage now matches Outlook levels.
The data indicates that Copilot queries per user rose nearly 20 per cent quarter on quarter. Nadella described the momentum as a daily habit of intense usage, noting that the number of companies paying for over 50,000 seats has quadrupled. Major enterprise clients holding more than 90,000 seats each include Bayer, Johnson \& Johnson, Mercedes, and Roche.
A new agreement with Accenture covers more than 740,000 seats, which Nadella described as the company's largest Copilot win to date. The tool, integrated into core applications such as Word, Excel, and Outlook, is now defaulting to an 'Agent mode' for multi-step tasks. This feature allows the software to perform actions directly within documents, enabling users to delegate and complete work more efficiently.
The platform supports multiple AI models by default, including Anthropic's Claude, with intelligent auto-routing capabilities. Nadella emphasised that Copilot is not dependent on any single model, allowing agents to use multiple models together to generate optimal responses. Morgan Stanley analyst Keith Weiss commented during the earnings call that the reported numbers were super impressive and exceeded most expectations.
This growth comes despite a lingering market perception that few users actually adopt or utilise Copilot effectively. The announcement highlights a surge in large-scale enterprise adoption, contrasting with previous doubts about the utility of the software. Microsoft previously announced the general availability of Copilot's agentic capabilities last week, which has coincided with this spike in engagement.
While the specific timeframe for the 20 million figure is tied to the current quarter's earnings call, the trend mirrors broader AI-driven growth elsewhere. For instance, Alphabet's Google recently saw a 19 per cent surge in revenue attributed to AI-powered search experiences, suggesting a wider industry shift toward integrated artificial intelligence tools.
