Anthropic is fielding preemptive offers for a roughly $50 billion funding round at a valuation between $850 and $900 billion, according to Bloomberg and TechCrunch reporting from April 29–30. The terms are not finalized — the company has not accepted any offer — but TechCrunch sources say a deal could close within two weeks. The round would more than double Anthropic's February 2026 mark of $380 billion and put it ahead of OpenAI, which closed earlier this year at an $852 billion post-money valuation.
The jump is being driven by revenue, not just narrative. Anthropic's annualized revenue has crossed $30 billion, with Claude Code as the standout growth driver. The fundraising also lines up with a potential IPO as soon as October — meaning the new round functions as a pre-IPO crossover, the kind that lets late-stage investors lock in a position before public-market pricing takes over.
Two structural shifts make the headline number less surprising than it first reads. Google's $40 billion commitment last week and Amazon's $5 billion top-up on the existing partnership both routed compute to Anthropic at a scale that makes the company's revenue trajectory more credible. And the recent restructuring of OpenAI's Microsoft deal — which freed OpenAI to sell on AWS and Google Cloud — has weakened the 'one frontier lab per cloud' framing investors used in 2024. Anthropic is now the bet on the cloud most willing to pay for it.
Takeaway for learners: when a private company's valuation doubles in ten weeks, the question to ask is what changed in the underlying contracts, not the model. Anthropic's jump tracks compute commitments and enterprise revenue, both of which are checkable. Valuation by itself tells you what investors are willing to pay; the contracts tell you why.
