Microsoft Reveals It’s the No. 2 Seller of AI Apps Behind OpenAI

Microsoft’s slightly-slowing growth in cloud server rentals cast a pall over its quarterly earnings report on Wednesday, but the company had a salve to numb that sting: It’s generating significant revenue from AI software subscriptions.

During its earnings call, CEO Satya Nadella revealed one of the most hotly anticipated figures investors and competitors have been waiting for: it has 15 million paying users of 365 Copilot, the flagship AI features in its Office apps suite for automating tasks including summarizing Teams meetings, generating PowerPoint presentations, or doing math in Excel spreadsheets.
