Microsoft rebuilds Copilot with coding and agents, adds usage billing after under 7% of seats paid

Microsoft on Friday unveiled a redesigned Copilot app that puts chat, a coding tool and a persistent AI agent in one place. The company's announcement describes three parts: Home, which combines Chat and the task-running Cowork feature with Word, Excel and PowerPoint built in; Code, which lets non-programmers build internal apps and automations on the same technology as GitHub Copilot; and Autopilot, an agent that keeps working when the user is not, and which The Verge reports is the renamed Scout assistant.

Microsoft shares were up 3.38% at $514.75 at 10:53 a.m., according to Nasdaq.com. CNBC noted the stock was up only 3% for the year through Thursday, behind the Nasdaq and most megacap peers.

The adoption number behind the relaunch

CNBC reported that fewer than 7% of Microsoft's more than 450 million commercial Office 365 seats carry a license for the Copilot add-on. That puts paid Copilot seats below roughly 31.5 million, by our arithmetic. At the $30 per user per month list price CNBC cited, even that ceiling would be under about $945 million a month, or around $11.3 billion a year, before any discounts. The other 93% of seats are the opportunity Microsoft is trying to reach, and it is the reason this is a relaunch rather than a feature update.

Microsoft's Copilot chief Jacob Andreou told CNBC that adding coding is partly Microsoft catching up with bundled tools from OpenAI and Anthropic, whose models Microsoft still uses inside the app.

What changes on the bill

The standard Copilot license still covers Copilot in chat and in Word, Excel, PowerPoint, Outlook and Teams. The new Cowork, Code and Autopilot features will be billed by usage, according to CNBC and The Verge. Microsoft is pairing that with what it calls FinOps for AI tools to help administrators track and cap spending.

For a small firm on Microsoft 365, that is the practical change. A 20-person office licensing Copilot at list price knows its cost today: $600 a month. Once staff start setting agents to watch Teams channels or run recurring tasks overnight, part of the bill will depend on how much work those agents do. Microsoft has not published usage rates in the materials we read, so there is no way yet to put a number on that second part. Owners who hand an agent a recurring job should expect to watch the spend closely in the first months.

Timing

• Home and Code roll out to Microsoft's Frontier early-access program in the coming weeks.
• Autopilot expands to private preview at the end of this month.
• No date was given for general availability or pricing.

For investors, the next read on whether usage billing lifts Copilot revenue will come with Microsoft's fiscal first-quarter results. Related: what Anthropic's latest price cut really is.
