Meta and Microsoft pull back from Claude as Anthropic transforms from partner into competitor

Meta and Microsoft, two of Anthropic's biggest enterprise customers, are sharply cutting their use of Claude. Microsoft slashed the monthly per-employee budget in its cloud division from $100,000 to $10,000, while Meta halved its Claude Code users to 30,000. Both companies are pushing their own AI tools instead. For Anthropic, that reliance on a few major clients is turning into a strategic risk.
