A company accidentally spent $500 million on Anthropic's Claude AI in a single month after failing to set usage limits on employee licenses. The incident highlights the risks of unrestricted AI access, as costs can spiral out of control without proper oversight.
Anthropic announced a run rate revenue of $47 billion, raised $65 billion in a Series H round, and achieved a post-money valuation of $965 billion.
Anthropic's run-rate revenue has hit $47 billion, up from $30 billion in April and $14 billion in February 2026, according to its $65B Series H filing. The annualized figures show extremely rapid growth, though some observers have expressed skepticism about the projections.
Simon Willison argues Anthropic and OpenAI have found product-market fit through enterprise coding agents. Both companies shifted to API-based enterprise pricing, and recent models cost more. Stories of Uber blowing its AI budget and Microsoft canceling Claude Code licenses suggest customers are paying high prices for genuinely useful tools, making April 2026 a new revenue inflection point.
