Court documents shed light on Google's stake in Anthropic. Until now it has owned a 14% stake, investing more than $3 billion in the startup across multiple rounds, but Google plans to add another $750 million in September through convertible debt.

The filing, seen by The New York Times, also states that Google cannot legally own more than 15%. In addition, it may have no voting rights in Anthropic, no board seats, and no board observer rights.

Anthropic does use Google Cloud for some of its training and inference work, but has more publicly talked about its work on Amazon Web Services.

Amazon, Anthropic's primary cloud partner, has invested around $8 billion in the startup. The company also is building a cluster of Trainium2 UltraServers called Rainier that contain hundreds of thousands of Trainium chips interconnected with third-generation, low-latency petabit-scale EFA networking, to be used exclusively by Anthropic.

In Anthropic's latest funding round earlier this month, the company raised $3.5 billion at a $61.5 billion post-money valuation.

Google, which is developing its own tech while quietly funding competitors, is taking a chance on AI startups. The U.S. Department of Justice recently dropped a proposal to force the company to sell its investments in AI companies such as OpenAI and Anthropic that could favorably boost its competition in online search.

The news outlet Futurism via The Information reports Google cofounder Larry Page is reportedly launching a new AI startup called Dynatomics and has hired hired a few engineers to work on AI-driven product design for product manufacturing.

Chris Anderson, the former chief technology officer of Kittyhawk, an electric aircraft company that was once funded by Page, is leading the new startup.
