The investment also reflects the changing dynamics among key players in this segment, particularly in light of the previously dominant partnership between Microsoft and the OpenAI startup, with which it has collaborated since 2019 and holds a roughly 27% stake worth around $135 billion. The collaboration with Anthropic also reflects Microsoft’s commitment to its Azure infrastructure. Anthropic has agreed to purchase up to $30 billion in Azure compute capacity and has secured guaranteed access to additional computational resources up to one gigawatt in power. For Microsoft, this is a long-term contract that directly supports the growth of its cloud segment, while also reinforcing its position as a critical AI infrastructure provider.
What Nvidia Gains
Nvidia, which is entering Anthropic in an even more prominent way, views the partnership as a key opportunity to optimize its own computing platforms. Anthropic has committed to purchasing one gigawatt of capacity on Nvidia systems, including the latest architectures, Grace Blackwell and Vera Rubin. This commitment strengthens Nvidia’s position as the dominant supplier of AI accelerators, while also guaranteeing demand at a time when computing capacity is one of the rarest resources in the entire industry. The collaboration also allows for tight technical integration between Claude’s models and Nvidia hardware, improving efficiency and reducing latency in both training and inference.
Anthropic Gains Capital
Founded in 2021 by former OpenAI researchers, Anthropic is now receiving a combination of capital, cloud capacity, and computational infrastructure that will significantly accelerate the development of its Claude models. The company continues to collaborate with AWS, which has been its key provider for training environments in 2023 and 2024. Partnerships with Amazon, Microsoft, and Nvidia are creating a robust and diversified ecosystem for Anthropic.
Investment Implications
From an investment perspective, the entire deal serves as a major signal of market direction. Both Microsoft and Nvidia are solidifying their positions at the top of the AI supply chain, with Microsoft in cloud services and Nvidia in computing accelerators, while Anthropic is emerging as one of the world’s three most significant model creators. So, the market is now entering a phase where strong alliances are forming between chip providers, cloud infrastructure, and frontier model creators.
