Elon Musk’s AI ambitions just got a whole lot more tangible, and maybe a bit more secretive too.
An affiliate of Phoenix Investors says it has sold the Colossus I data center property in Memphis, Tennessee to a subsidiary of SpaceX for a staggering $185 million. The massive site spans 217 acres and includes a 785,000-square-foot facility already tied to xAI operations.

Here is where things get interesting: the press release never actually names the SpaceX subsidiary that bought the property.
That omission feels notable.
The release simply says the buyer was “a subsidiary of SpaceX,” but offers no LLC name, corporate entity, or additional details. In an era where Musk’s companies increasingly overlap with one another, the vague wording only adds to the mystery surrounding how xAI, SpaceX, X, and Musk’s broader AI strategy are being structured behind the scenes.
You know what? Maybe that is intentional.
The AI race is no longer just about who has the smartest chatbot. It is becoming a battle over who controls the underlying infrastructure. Datacenters, GPUs, networking, cooling systems, electricity, and land are quickly becoming just as valuable as the AI models themselves.
Owning a facility like Colossus I outright could give Musk tighter control over xAI’s future while reducing dependence on outside cloud vendors or landlords. Leasing hyperscale infrastructure is expensive, especially when giant AI models are training nonstop. Ownership potentially offers long-term cost savings and more flexibility to expand aggressively.
If you look at Musk’s history, controlling the entire stack is sort of his signature move.
Tesla builds batteries and charging networks. SpaceX builds rockets and satellite internet. Starlink controls connectivity. Neuralink is working on brain interfaces. Now xAI appears to be moving toward the same vertically integrated approach, where the infrastructure itself becomes part of the competitive advantage.
The wording in the release raises another eyebrow too. It refers to “X-AI” as a subsidiary of SpaceX, which is not how xAI has traditionally been described publicly. Whether that is sloppy wording, legal restructuring, or an accidental reveal about how closely tied these businesses have become is unclear.
Either way, the lines separating Musk’s empire are looking blurrier by the day.
The Memphis facility itself has already drawn attention because of the enormous power and cooling demands associated with modern AI infrastructure. Across the country, communities are beginning to question whether giant AI datacenters are economic opportunities, environmental headaches, or both.
For Musk, though, the strategy may be simple: if AI is the future, owning the land underneath it could be just as important as owning the software running on top.
