CoreWeave (CRWV.US) has reached a multi-year computing power leasing agreement with Anthropic, gaining another top AI client.

On Friday, CoreWeave (CRWV.US) added a new member to its growing list of well-known clients, announcing a multi-year data center leasing agreement with the artificial intelligence (AI) startup Anthropic PBC. CoreWeave announced in a statement on Friday that the agreement will help Anthropic build and deploy its Claude AI model. The collaboration will gradually roll out computing resources later this year, with plans to further expand in the future. CoreWeave CEO Michael Intrator said in the statement, "The focus of AI is no longer just infrastructure, but how to translate models into real value through platforms. We are delighted to work with Anthropic at the forefront of model deployment and performance in production environments." Intrator added in an interview that the provided computing power will cover various NVIDIA Corporation (NVDA.US) chip architectures in US data centers. The specific financial terms of the agreement were not disclosed by the two companies. Boosted by this news, CoreWeave's stock price rose over 6% in pre-market trading. The stock rose 3.5% on Thursday, leading to a cumulative increase of 28% so far this year. This announcement is the latest development in a busy week for CoreWeave. The company announced a $21 billion expansion agreement with Meta Platforms (META.US) on Thursday and issued two bonds. CoreWeave is a representative player in the "neoclouds" camp, focusing on providing leasing services for high-performance cloud computing resources for AI workloads. Customers including Microsoft Corporation (MSFT.US) have started using neocloud providers to rapidly improve their capabilities in building and providing AI products. In February this year, CoreWeave stated that the company has 43 active data centers and has signed contracts for over 3 gigawatts of power supply for server clusters. Intrator said that with the agreement with Anthropic, nine of the top ten AI model providers are now using CoreWeave's cloud platform. Like OpenAI, Anthropic has been at the forefront of the explosive growth of AI services. Faced with what they call "unprecedented demand," Anthropic sometimes struggles to maintain its online service capacity. As a result, the company is actively expanding its computing power, including a commitment to invest $50 billion to build new AI data centers in the US. Based in San Francisco, Anthropic is one of the highest valued private companies, with a valuation of $380 billion, including the recent $30 billion funding raised. Earlier this week, Anthropic also announced partnerships with Broadcom Inc. (AVGO.US) and Alphabet Inc. Class C (GOOGL.US) to obtain a 3.5 gigawatt energy supply. It is understood that 1 gigawatt of power is enough to meet the electricity needs of approximately 750,000 US households simultaneously.
