Elon Musk and Anthropic have entered a $4 billion [1] agreement to make SpaceX the primary compute and data-center provider for the AI research company.

The deal marks a significant pivot in the relationship between the two entities, as Musk previously used his public platform to attack the company's values. By securing this agreement, Musk positions SpaceX as a critical infrastructure pillar for one of the most prominent AI developers in the world.

Under the terms of the agreement, Anthropic will utilize the Colossus 1 data center in Memphis, Tennessee, to host its compute capacity [2]. This arrangement effectively makes Musk a "data landlord" for the firm [1].

The partnership follows a period of public hostility. Approximately three months before the announcement [2], Musk said Anthropic was "evil" and "misanthropic" [2]. Despite those comments, the two parties reached the multi-billion-dollar deal this week.

SpaceX is leveraging its massive infrastructure to monetize compute power, diversifying its revenue streams beyond aerospace and satellite services. This move allows Musk to integrate his hardware capabilities with the software needs of his competitors.

Industry observers note the strategic nature of the physical infrastructure. One report said that he who controls the data center, really does control the application of artificial intelligence right now [1].

While Fortune reported the deal value at $4 billion [1], other reports on the announcement did not specify a dollar amount [3]. The agreement ensures that Anthropic has the necessary processing power to continue its AI research and development, while SpaceX expands its role in the AI ecosystem.

Elon Musk is now taking $4 billion to become its data landlord.

This agreement highlights a shift in the AI race where the control of physical compute infrastructure—the 'silicon and steel'—is becoming as valuable as the models themselves. By hosting a competitor's core operations, Musk creates a dependency that grants SpaceX significant leverage over the operational capacity of a major AI player, regardless of their ideological differences.
