Investor interest in Anthropic has reached a feverish pitch.

The maker of the Claude AI assistant has received multiple preemptive offers to raise fresh capital of around $50 billion at a valuation in the $850 billion to $900 billion range, according to half a dozen sources familiar with the matter. Bloomberg and Business Insider reported earlier this month that Anthropic received multiple preemptive bids at an $800 billion valuation, but at that time, the company had not yet committed to a fundraise.

Sources say, however, that Anthropic is finding it difficult to resist the pressure to secure more funding in what could be its final round of private fundraising before a potential IPO. The company is expected to make a definitive decision on the round and its valuation at a board meeting in May, one person told TechCrunch.

The round is expected to total $40 billion to $50 billion, according to people familiar with the company. But investor demand appears to be much higher given the company’s rapid growth, which shows no sign of slowing. Investors are clamoring to get into the round. One institutional investor prepared to commit as much as $5 billion has yet to secure a meeting with Anthropic CFO Krishna Rao, according to a source.

Anthropic announced this month that its annual revenue run rate has surpassed $30 billion, which is a dramatic increase from roughly $9 billion at the end of 2025. The company’s run rate is currently closer to $40 billion, one of the people with knowledge of the company’s financials said.

Antrhopic declined to comment.

A large portion of that revenue is driven by 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 its offerings into new industries, including finance, life sciences, and healthcare.

Anthropic raised its last round at a $380 billion valuation in February. If the company proceeds with another fundraise at the terms described by TechCrunch’s sources, it will not only more than double its valuation but also match or surpass that of its chief rival. Also in February, OpenAI closed a record-breaking $122 billion round at an $852 billion post-money valuation.
