Anthropic, the maker of the Claude AI assistant, has received multiple offers to raise around $50 billion at a valuation in the $850 billion to $900 billion range. This could be Anthropic's final round of private fundraising before a potential IPO. The company is expected to make a decision on the round and its valuation at a board meeting in May. The round is likely to total $40 billion to-$50 billion, but investor demand is higher due to the rapid company's rapid growth. Anthropic's annual revenue run rate has surpassed $30 billion, a significant increase from $9 billion at the end of 2025.
