Anthropic Set To Pay xAI $1.25 Monthly For Compute Services

Anthropic shocked the AI community earlier this month by obtaining the whole output of the Colossus 1 data centre outside Memphis, Tennessee, with an agreement to purchase over 300 megawatts of compute.

In order to obtain enormous artificial intelligence processing power, Anthropic has committed to pay xAI up to $1.25 billion every month. SpaceX’s S-1 IPO registration filing with the SEC served as the official announcement of the massive acquisition. 

It turns out that it is expensive to compute at such a scale. Through May 2029, Anthropic will pay xAI $1.25 billion per month, with a discounted rate for the first two months as xAI finishes its ramp-up. The purchase might generate over $40 billion in income for xAI overall.

SpaceX’s S-1 filing with the SEC provided information about the transaction. The company claimed that the agreement “allows us to monetize unused compute capacity in our infrastructure.” Both parties may end the agreement with ninety days’ notice under the conditions of the agreement.

The filing said, “We anticipate entering into additional similar services contracts.”

xAI now has a mixed position in the AI sector as a result of the move. The majority of players either construct data centers for their own use or for the use of others, rarely both at the same time. This new paradigm, commonly referred to as a “neocloud,” allows AI firms to offset infrastructure expenses by serving as a cloud provider when their own consumption is insufficient.

The arrangement, according to SpaceX, is a wise use of resources. The statement read, “We think our dual monetization strategy offers multiple pathways to generate returns on invested capital.” However, it’s difficult to ignore the underlying message: xAI seems to have overbuilt its computational capability and needed to figure out how to make money off of it before going public. Recent months have seen a sharp decline in the use of Grok, xAI’s flagship AI helper, freeing up servers that the business is now selling to one of its nearest rivals.  

Under the key deal terms, Anthropic secures the entire 300-megawatt output of xAI’s Colossus 1 facility near Memphis, backed by over 220,000 Nvidia GPUs, the contract is expected to run through May 2029, with potential total revenue exceeding $40 billion for Elon Musk’s infrastructure. The agreement also grants Anthropic expansion rights to Colossus 2 (featuring Nvidia GB200 Blackwell chips), includes a 90-day mutual exit clause, and offers a discounted monthly rate during the first two months of server ramp-up.

The strategic impact of this intends to focus on the following;

• Claude Expansion: According to Anthropic, the new computing capacity will immediately support higher usage limits for both Claude Code and its developer APIs.
• The “Neocloud” Model: This transaction introduces a hybrid approach to infrastructure. When internal demand for Grok falls below capacity, xAI offsets its substantial data center construction costs by functioning as a third-party cloud provider.
• Financial Winds: The monthly cash injection nearly doubles SpaceX’s historical run-rate for space-related revenues. At the same time, the arrangement helps Anthropic scale up as it moves closer to a highly anticipated public debut on the stock market.
