Microsoft has for the first time reported Microsoft 365 Copilot adoption stats, boasting this week of 15 million paid seats (individual user licenses). There are “multiples more enterprise chat users” Microsoft CEO Satya Nadella said during the company’s earnings call Wednesday — a reference to Copilot Chat, a simplified version of the AI assistant available to Microsoft 365 customers at no extra cost. (Microsoft did not provide specific figures.) Analysts said the number of paid user seats lags expectations at this stage, given the company’s efforts to market Microsoft 365 Copilot and position it as central to its AI strategy. “Microsoft’s disclosure of 15 million Microsoft 365 Copilot paid users represents disappointing uptake of the tool — just 3.3% of the 450 million-strong Microsoft 365 user base, despite reorganizing the Microsoft 365 product and go-to-market around Copilot,” said J.P. Gownder, vice president and principal analyst at Forrester.
