Anthropic weighs $50 billion fundraising round at $850B to $900B valuation

Investor interest in Anthropic has intensified as the company behind the Claude AI assistant weighs a substantial new fundraising round that could value it at roughly $850 billion to $900 billion. According to half a dozen sources familiar with the matter, the startup has received multiple preemptive offers to raise around $50 billion. Bloomberg and Business Insider reported earlier this month that Anthropic received bids at an $800 billion valuation, though the company had not committed at that time. Sources now say Anthropic is under pressure to secure what could be its final private round before a potential initial public offering, with a board meeting in May expected to produce a definitive decision. The round is expected to total between $40 billion and $50 billion, though investor demand may push the figure higher. 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, a sharp rise from roughly $9 billion at the end of 2025. One person with knowledge of the company’s financials said the run rate is now closer to $40 billion. Much of that revenue stems from AI coding tools, including its Claude Code and Cowork platforms. Anthropic raised its last round in February at a $380 billion valuation. At the upper end of the current range, its new valuation would match or surpass that of rival OpenAI, which closed a $122 billion round in February at an $852 billion post-money valuation.
