Microsoft’s Copilot has 20M paid users, and no, they’re not just logging in once

Microsoft dropped a number this week that cuts against the persistent narrative that Copilot is a ghost town: over 20 million paid users, and they claim engagement is actually going up.

That’s a lot of people paying for something that critics love to call a glorified autocomplete. But the data, if accurate, suggests otherwise. Microsoft says these aren’t just trial accounts or people who clicked “upgrade” once and forgot about it. They’re tracking active usage across Office apps, Teams, and the rest of the M365 ecosystem.

I’ve been skeptical of Copilot since launch, mostly because the demos felt staged and the real-world workflow integration seemed clunky. But 20 million paid seats is hard to dismiss. For context, that’s more users than Slack had at its peak before Salesforce bought it. And these are people paying extra on top of their existing Office subscriptions.

What’s interesting is how Microsoft frames this. They’re not just bragging about raw numbers — they’re specifically pushing back on the idea that AI assistants are a fad that nobody actually wants to use. The engagement metrics they shared show people coming back, not just poking at it once out of curiosity.

Of course, we don’t have independent verification. Microsoft has a history of bundling metrics in ways that make things look better than they are. “Paid users” could include enterprise seats that were purchased but barely used. But even so, the scale is notable.

The bigger picture here is that Microsoft is betting the entire future of Office on Copilot being sticky. If these numbers hold up, they might actually pull it off. If not, we’ll see a lot of discounted renewals next year.

Either way, the “nobody uses AI” crowd has a tougher case to make now.
