Only 3.3 percent of Microsoft 365 and Office 365 users who touch Copilot Chat actually pay for it, an awkward figure that landed alongside Microsoft's $37.5 billion quarterly AI splurge and its insistence that the payoff is coming.

That single percentage stat undermines the company's carefully polished Copilot success story. On its Q2 FY26 earnings call, Microsoft repeatedly cited "record" AI momentum, telling investors it now has 15 million paid Microsoft 365 Copilot seats, with seat growth up more than 160 percent year-over-year. Satya Nadella described Copilot as "becoming a true daily habit," claiming daily active users are up tenfold year-over-year and that average conversations per user have doubled.

What Microsoft did not articulate is how small that paid footprint looks against the vast base of Microsoft 365 users experimenting with Copilot Chat for free, as highlighted by Directions on Microsoft analyst Mary Jo Foley.
