Anthropic seeks $50B funding round at up to $900B valuation, could close within two weeks

Anthropic is seeking to raise approximately $50 billion at a valuation of $850–900 billion, which would make it the world's most valuable private AI company. Investors were given a 48-hour deadline to submit capital allocations, with the round expected to close within two weeks of April 30, 2026. The valuation would more than double Anthropic's February 2026 valuation of $380 billion. Anthropic's annual revenue run rate has surpassed $30 billion, with some sources placing it closer to $40 billion. If completed at the reported valuation, Anthropic would surpass OpenAI (last valued at $852 billion) and would represent what is expected to be the company's last private round before a potential IPO. The fundraise underscores the accelerating financial scale of the frontier AI industry, where a single round now rivals the total annual VC funding of entire sectors.
