Anthropic Signs $1.25 Billion Monthly Compute Deal With xAI

Anthropic has entered into a landmark agreement with xAI, under which Anthropic will pay $1.25 billion per month to secure significant computing resources from the Colossus 1 data center near Memphis, Tennessee. The arrangement, revealed through SpaceX’s S-1 filing with the U.S. Securities and Exchange Commission, positions Anthropic to expand its artificial intelligence operations while providing xAI with a substantial and predictable source of revenue.

The contract stipulates that Anthropic will gain access to 300 megawatts of compute—a measurement describing the total energy capacity required to support AI model training and operation at scale. Compute resources like these are critical for training large language models and other advanced AI systems, which demand enormous processing power. The agreement also includes a discounted rate for the first two months as xAI increases its service capacity. Over the duration of the contract, which extends through May 2029, total revenue for xAI could exceed $40 billion, subject to potential early termination by either party with 90 days’ notice.

SpaceX, which operates the Colossus 1 facility and owns xAI, stated in its filing that the deal allows the company to “monetize unused compute capacity in our infrastructure.” The unique structure of the deal enables xAI to function not just as an AI developer but also as a compute provider—a hybrid role increasingly referred to in the industry as a "neocloud." This model allows AI firms to operate as cloud service providers during periods of lower demand, offsetting the costs of large-scale data center infrastructure.

As AI applications mature, some providers are grappling with fluctuations in demand. According to the filing, usage of Grok, xAI’s main AI assistant, has reportedly declined, offering the company an opportunity to sell excess compute resources to Anthropic, a direct competitor in the generative AI space. SpaceX indicated in the documents an expectation to pursue similar service agreements in the future, signaling a broader trend across the AI industry as companies attempt to navigate both infrastructure investment and excess capacity.

The agreement could have wider implications for the AI market, particularly as firms increasingly seek flexible infrastructure strategies to manage expenses. The contract’s termination clause provides both Anthropic and xAI the ability to adapt quickly to shifts in the rapidly evolving landscape of AI compute demand and availability.

This development highlights an emerging dual-role strategy among leading AI firms—balancing the roles of consumer and provider of critical data center resources—which may shape infrastructure investment and competitive dynamics across the industry in the years leading up to public offerings and further expansion.
