xAI Selling $1.5 Billion of Compute to Anthropic Each Month

Anthropic, a leading artificial intelligence company known for its Claude language model, is set to pay xAI an astonishing $1.5 billion each month for computing power. This arrangement, revealed through a SpaceX regulatory filing, will see Anthropic utilise the full 300 megawatts of capacity at the Colossus 1 data centre near Memphis, Tennessee. The deal is expected to run until May 2029, potentially generating over $40 billion in revenue for xAI, which operates under the SpaceX umbrella. The Colossus 1 data centre has previously attracted criticism over its environmental impact, with concerns raised about pollution and sustainability. Originally, the computing resources were intended to support Grok, xAI’s own AI system, but lower-than-expected demand for Grok has left much of the capacity underused. Faced with an upcoming SpaceX initial public offering, the company has opted to lease this surplus capacity to Anthropic, a direct competitor in the AI space, raising questions about the strategic implications of this decision. The contract between Anthropic and xAI includes a clause allowing either party to terminate the partnership with 90 days’ notice, introducing some uncertainty into xAI’s future revenue stream. Nonetheless, the scale of this agreement marks a significant milestone in the commercialisation of AI infrastructure, signalling robust demand for large-scale compute resources. The SpaceX filing also hints at plans to secure similar contracts in the future, suggesting that xAI aims to further capitalise on its computing assets. This development highlights the intense competition and investment within the AI industry, where companies are willing to commit vast sums to secure the computational power necessary for advancing their models. It also underscores the evolving relationship between SpaceX, xAI, and other players in the sector, as well as the broader questions around the environmental and economic sustainability of such massive data centres. As the AI landscape continues to evolve, the outcomes of this partnership will be closely watched by industry observers and investors alike.
