Company reportedly racked up $500M in Claude charges in one month

An unnamed enterprise customer allegedly accumulated roughly $500 million in Claude charges in a single month after failing to set employee usage limits. The figure is unconfirmed by the company or Anthropic; token-based billing and automated agent loops let costs scale silently.

• About $500M in Claude charges in one month without usage limits
• Token billing charges per model call and agent loop
• Anthropic estimates Claude Code at $150–250 per developer monthly
• Neither the customer nor Anthropic confirmed the figure
