Google will invest at least $10 billion in Anthropic, and that amount could rise to $40 billion if Anthropic meets certain performance targets, Bloomberg reports.

The investment follows Amazon’s $5 billion initial investment in Anthropic a few days ago; the Amazon deal also leaves the door open to further investment based on performance. Both investments value Anthropic at $350 billion.

Anthropic has seen rapid growth in the use of its Claude models and related products, such as Claude Code, which promises to significantly increase the speed and efficiency with which companies or individuals can develop software. (The reality varies from big improvements to setbacks, depending on the nature of the project and company, how Claude Code is used, and many other factors.)

Several factors contributed to Anthropic’s success in recent months, including controversies around OpenAI and its ChatGPT product and models, more robust agentic workflows, and new products like Claude Cowork, which does some of the same things for general knowledge work tasks as Claude Code does for software development.
