Microsoft Ignite opens Nov. 17 with Copilot seat count still undisclosed

Microsoft's Copilot disclosure history shows a shift in emphasis. The company began 2026 by putting a number on paid seats: Nadella reported 15 million in January, over 20 million by April, and over 30 million by July, with net seat additions more than doubling from the prior quarter. The October call broke that pattern. When an analyst asked directly, CFO Amy Hood said Microsoft did not disclose an update on the Copilot number that quarter and instead pointed to momentum in revenue and usage. Hood said Copilot revenue growth picked up from the previous quarter with continued adoption in Microsoft 365, GitHub, and security, but she did not share a dollar figure. The usage metrics Microsoft did provide were strong, yet they do not show how many seats customers pay for. As more customers pay by usage, a seat count may become a less complete gauge of the business over time, which could explain the change in disclosure. Last year's Ignite was mainly about products—Agent 365, Work IQ, and Microsoft 365 Copilot Business—and the paid count came two months later on the January call. That pattern suggests Ignite may again be a product event rather than the venue for a new paid-seat figure.
