Key Takeaways:
A regulatory filing has revealed the staggering cost of AI supremacy, with Anthropic agreeing to pay rival xAI $1.25 billion per month for cloud computing infrastructure in a deal that reshapes the competitive landscape. The agreement, which runs through May 2029, underscores the intense demand for processing power and establishes a new "neocloud" business model for Elon Musk's SpaceX, xAI's parent company.
"This structure allows us to monetize unused compute capacity in our infrastructure, while still permitting reallocation of the capacity for our own internal initiatives if needed in the future," SpaceX stated in its S-1 filing with the SEC. The document, filed ahead of a planned initial public offering, provides the first financial details of the compute deal announced in early May.
The arrangement gives Anthropic, developer of the Claude AI models, immediate access to more than 300 megawatts of processing power, including the entire output of the Colossus 1 data center in Tennessee and capacity from the newer Colossus 2 facility. This infrastructure comprises over 220,000 Nvidia GPUs, according to reports. Anthropic, which confirmed the monthly payment, will use the compute primarily for inference — the process of running trained AI models to generate outputs for its customers.
The deal, valued at over $40 billion if it runs to term, highlights the immense capital expenditures required to compete in the AI sector. SpaceX's S-1 reveals that its AI-related losses from operations grew fourfold to over $6 billion last year, driven by cloud costs and GPU depreciation. The filing even lists "manufacturing our own GPUs" as a potential future capital expenditure, signaling a desire to reduce its reliance on Nvidia and control a crucial part of the supply chain, a move that would put it in direct competition with the chipmaking giant.
By selling compute at this scale, SpaceX and xAI are not just funding their own AI ambitions; they are entering the cloud infrastructure market and competing directly with giants like Amazon Web Services and Google Cloud. The move is particularly complex as SpaceX itself is a major customer of Google Cloud for its Starlink satellite internet division. This "neocloud" strategy of building massive data centers for internal use and leasing excess capacity allows AI companies to offset billions in infrastructure costs.
The subtext, however, is that xAI may have overbuilt its capacity relative to the current usage of its flagship product, the Grok chatbot. By leasing a significant portion to a top rival, xAI secures a massive revenue stream ahead of its IPO, effectively asking Anthropic to help finance its operations. Either party can terminate the contract with just 90 days' notice, providing both with flexibility in the volatile AI market.
For Anthropic, the deal is a strategic coup, allowing it to bypass near-term capacity constraints and secure the power needed to serve its rapidly growing customer base for products like Claude Pro. It gets immediate access to a massive GPU cluster without waiting for its other cloud partnerships to come fully online.
The transaction puts pressure on all players in the AI ecosystem. For cloud providers like Google and Amazon, it signals the emergence of a new, well-capitalized competitor. For Nvidia, it demonstrates the insatiable demand for its hardware but also highlights how its customers are exploring ways to mitigate their dependence. For investors, the deal validates the thesis that access to compute is the primary bottleneck and key differentiator in the AI race, a factor that will heavily influence the upcoming SpaceX IPO.
