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

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.
