Anthropic Eyes $50B Raise at $900B Valuation, Likely Last Private Round Before IPO

Anthropic is racing to close what would be one of the largest private fundraises in tech history, with reports indicating the Claude developer is requesting investor allocations within 48 hours for a roughly $50 billion round at a valuation near $900 billion. According to TechCrunch sources, the deal is expected to close within two weeks and final pricing may exceed the $900 billion target as demand outstrips the slots available.

The numbers represent a stunning leap. Anthropic last raised in February 2026 at a $380 billion valuation, meaning the new round would more than double the company's worth in roughly three months. It would also leapfrog rival OpenAI, which closed a $122 billion round at an $852 billion post-money mark earlier this year. Bloomberg, CNBC, and the Wall Street Journal have separately reported on preemptive offers in the $850–900 billion range.

Behind the surge in valuation is a revenue ramp that is hard to overstate. Anthropic's annualized revenue run rate climbed from approximately $9 billion at the end of 2025 to more than $30 billion by the end of March 2026, and sources told TechCrunch the figure is now closer to $40 billion. Demand for Claude across enterprise, government, and developer channels — including the recently struck Amazon Bedrock partnership and FIS banking deal — has accelerated through the spring.

The upcoming round is widely expected to be Anthropic's last private financing before going public. The company's IPO has been pencilled in for as early as October 2026, the timing dictated as much by ballooning compute requirements as by market opportunity. Some early backers from 2024 and prior are reportedly skipping this round, content to wait for a richer payoff at the public listing rather than pay near-trillion-dollar entry prices today.

Anthropic has not officially confirmed the round, and a board decision on whether to proceed at these terms is still pending. Even so, the range of preemptive offers and the reported timeline make clear that capital is no longer the binding constraint on frontier AI labs — compute is. With Google having committed up to $40 billion in cash and TPU credits in late April, and a fresh $50 billion equity injection on the horizon, Anthropic appears to be lining up the war chest required to keep pace with OpenAI in both training and inference scale.
