Microsoft Is Cutting Claude Code Access for Thousands of Engineers by June 30

Microsoft opened Claude Code to its Experiences + Devices division in December 2025, giving thousands of engineers, program managers, and designers access to Anthropic’s terminal agent. The experiment ran for less than six months. Now it’s over.

Rajesh Jha, Executive Vice President for the division, told staff that Claude Code licenses are being canceled by June 30. Engineers are being redirected to GitHub Copilot CLI, Microsoft’s own command-line AI coding tool.

Experiences + Devices covers Windows, Microsoft 365, Outlook, Teams, and Surface, so this isn’t a small group. The division ran Claude Code at scale, and by April 2026 monthly usage rates had climbed to between 84% and 95% of engineers in the program.

That adoption is exactly what makes the cancellation interesting. This isn’t a tool people stopped using. It’s a tool that became too popular.

The Cost Problem

Claude Code’s pricing is token-based on top of a base subscription fee. At light usage, that’s manageable. At the usage rates Microsoft saw, it wasn’t.

Per-engineer API costs ran between $150 and $250 per month for typical users. Power users, the ones running long agentic sessions or working on large codebases, were spending $500 to $2,000 per engineer per month. Across thousands of engineers, that adds up quickly.

Uber ran a similar experiment and hit the same wall harder. The company deployed Claude Code to roughly 5,000 engineers and burned through its entire 2026 AI coding tools budget in four months. One Uber executive clocked $1,200 in a single two-hour session. Uber’s CTO for Mobility and Delivery confirmed the budget exhaustion to The Information.

Both companies discovered the same thing: token-based pricing for agentic coding is hard to predict and easy to overshoot.

What Jha Said

Jha’s message to staff framed the switch as strategic, not just financial: “Claude Code was an important part of that learning. At the same time, Copilot CLI has given us something especially important: a product we can help shape directly with GitHub for Microsoft’s repos, workflows, security expectations, and engineering needs.”

That framing matters. Microsoft doesn’t just want to cut costs. It wants to run its own stack internally and use that to improve the product it sells to customers. Having its engineers use a competitor’s tool is a product conflict it can’t keep tolerating.

GitHub Copilot CLI runs at $39 per seat per month on a flat rate, with no token overage risk. It also integrates with GitHub repositories, enterprise security policies, and Microsoft’s existing identity and compliance infrastructure in ways Claude Code doesn’t.

The Timing

June 30 is the last day of Microsoft’s fiscal year. Canceling Claude Code licenses before that date closes the cost exposure for FY2026 and lets the company start FY2027 with Copilot CLI as the standard. It’s also a clean time to switch, since budget cycles reset and teams can plan around the new tooling from day one.

Microsoft engineers who’ve been using Claude Code will notice the difference. Copilot CLI is a capable tool, but it operates differently. Claude Code’s agentic model, long-context handling, and the way it manages multi-step tasks across large repos has been its selling point. How closely Copilot CLI matches that experience is something Microsoft will find out over the next few months.

The more significant signal here is what this does to the broader market. If Microsoft, one of Anthropic’s largest partners, couldn’t keep Claude Code in its developer workflow because of cost predictability, that’s a problem the whole industry has to address. The tools that survive enterprise procurement aren’t necessarily the best ones. They’re the ones that fit inside a budget.
