Sources: Anthropic could raise a new $50B round at a valuation of $900B

Anthropic, the company behind the Claude AI assistant, is weighing a massive new funding round of $40-50 billion at a valuation between $850-900 billion, according to half a dozen sources familiar with the matter. This would more than double the company's February valuation of $380 billion and match or surpass rival OpenAI's $852 billion post-money valuation from its recent $122 billion round. Investor interest is so intense that one institutional investor prepared to commit up to $5 billion has yet to secure a meeting with Anthropic CFO Krishna Rao. A final decision is expected at a May board meeting, and sources say the company is finding it difficult to resist pressure to secure what could be its final private fundraising before a potential IPO.

The company's rapid growth is the primary driver of this investor frenzy. Anthropic announced this month that its annual revenue run rate has surpassed $30 billion, a dramatic increase from roughly $9 billion at the end of 2025, with the current run rate closer to $40 billion. A large portion of this revenue comes from Anthropic's AI coding capabilities, specifically through its Claude Code and Cowork platforms. Many investors believe the company is only scratching the surface of its potential, given the massive opportunity to expand into new industries including finance, life sciences, and healthcare.
