The $4 billion round is led by Google, which has now invested over $3 billion in Anthropic across three separate tranches since 2023. Amazon remains a significant investor through its AWS arm, which made a $4 billion commitment in late 2023. The new round also includes participation from Salesforce Ventures, Spark Capital, and several sovereign wealth funds. The deal is structured as a mix of primary equity — going directly to the company — and secondary shares from early employees and investors who wanted liquidity. At $61B post-money, Anthropic is now valued at roughly 30x its annualized revenue, a premium that reflects investor confidence in the AI safety narrative and Claude's enterprise traction.

“Anthropic has done something very few AI companies have managed: translate genuine safety credibility into enterprise sales. Fortune 500 buyers who are nervous about AI risk specifically choose Claude. That's a durable competitive moat.”

Anthropic's CEO Dario Amodei confirmed in an internal memo (seen by multiple journalists) that the new capital is earmarked across three areas. The largest allocation — approximately 55% — goes toward compute for training Claude 4 and its successors. Claude 4 is described internally as a 'frontier reasoning model' targeting the same PhD-level benchmark territory as the leaked GPT-5 numbers. Another 30% will fund safety and interpretability research, consistent with Anthropic's Constitutional AI approach. The remaining 15% covers global hiring (particularly in Europe and APAC) and enterprise sales infrastructure.
