Meta and Microsoft seek to reduce employee use of Claude

The Information characterized Meta and Microsoft as looking to lower employees’ use of Claude; Business Insider reported that characterization.[1] The Information also described the two companies as among Anthropic’s largest corporate customers.[1] Microsoft’s published partnership commitments include continued access to Claude across several products.[4]

The number of Meta employees using Claude Code fell to about 30,000, from about 60,000 earlier in 2026, according to the report cited by Techmeme.[2] That is a decline of roughly half, based on the approximate figures reported.[2] The evidence gives no explanation for Meta’s change in usage, and it does not say that Meta has stopped using Claude Code. For teams assessing the news, the reported user count is a measure of internal adoption, not evidence by itself of why employees used the tool less.

Microsoft executives projected earlier in 2026 that the company would spend at least $1 billion on its internal use of Anthropic technology.[1] Microsoft has since cut that projected spending by more than a third.[1] The report attributes the reduction to cost savings and a decision to spend more time using Microsoft’s homegrown AI tools.[1] The evidence describes a change in projected internal spending; it does not give a new total or say that Microsoft has withdrawn Claude from customer-facing products.

Microsoft’s partnership announcement included Anthropic’s commitment to purchase $30 billion of Azure compute capacity, with additional capacity of up to one gigawatt to be contracted.[4] Microsoft said Foundry customers would be able to access Claude Sonnet 4.5, Claude Opus 4.1 and Claude Haiku 4.5.[4] Microsoft also committed to continue Claude access across GitHub Copilot, Microsoft 365 Copilot and Copilot Studio, and to invest up to $5 billion in Anthropic.[4] These commitments provide context for the reported effort to reduce employee use: internal consumption and the wider commercial partnership are distinct matters.
