Anthropic to pay xAI $1.25B monthly for compute
Earlier this month, Anthropic announced a major agreement to acquire 300 megawatts of computing power from xAI, securing the entire output of the Colossus 1 data center near Memphis, Tennessee. Under the terms of the deal, Anthropic will pay xAI $1.25 billion monthly for compute credits through May 2029, with a discounted rate for the initial two months while xAI completes its operational ramp-up. This arrangement is projected to generate over $40 billion in revenue for xAI. The specifics of the transaction were revealed in SpaceX's S-1 filing with the U.S. Securities and Exchange Commission. The agreement highlights a strategic shift for xAI, which operates as both a user of cloud infrastructure and a provider of services to others. Most industry players typically choose one path, either building data centers for their own internal use or leasing capacity to third parties. xAI, however, has adopted a hybrid model often referred to as a neocloud. This approach allows artificial intelligence companies to offset the high costs of infrastructure by acting as a cloud provider when their own usage does not fully utilize the available capacity. SpaceX described the deal as a way to monetize unused compute resources, stating that the dual strategy creates multiple pathways to generate returns on invested capital. Both parties retain the right to terminate the contract with 90 days' notice, and SpaceX indicated plans to enter into similar service agreements in the future. Despite the financial benefits, the deal suggests underlying challenges for xAI. The company appears to have overbuilt its computing capacity and sought immediate revenue streams ahead of its planned public offering. Data usage for Grok, xAI's flagship artificial intelligence assistant, has declined significantly in recent months, leaving substantial server capacity idle. Consequently, xAI is now selling this excess infrastructure to Anthropic, a direct competitor known for its Claude AI models. The transaction underscores the intensifying competition in the AI sector, where infrastructure scale and cost efficiency are becoming critical determinants of success. By securing such a massive amount of compute, Anthropic ensures it has the resources to train and run large-scale models, while xAI monetizes its assets to support its broader financial goals. The deal reflects a pragmatic solution to the high capital expenditure required in the AI industry, where surplus capacity must be leveraged to maintain viability.
