A rocket company is spending $74 billion on AI supercomputers: SpaceX unveils Texas and Arizona campuses, one drawing up to 6 gigawatts

Most people know SpaceX for rockets and Starlink satellites. Now the company is putting tens of billions of dollars into something else: supercomputers for AI.

On Nov. 12, 2026, at 11:08 a.m. EST (00:08 Nov. 13 Beijing time), SpaceX posted a thread on X laying out plans for two "supercompute campuses" and the community benefits attached to them. According to SpaceX's statement, as reported by Reuters and the Houston Chronicle, the two sites add up to more than $74 billion: more than $24 billion near Starbase, its launch site in South Texas, and roughly $50 billion in Cochise County, Arizona.

**What the campuses are for**

SpaceX says the computing will train its own "super intelligence" models and support science and engineering work. The Houston Chronicle reports SpaceX also described the Texas site as a place to develop technology for its plans to put data centers in space. Put simply, these are giant buildings full of AI chips, used to train and run AI systems.

**How big (all figures are SpaceX's plans)**

- Arizona: nine supercompute buildings plus support facilities, drawing up to 6 gigawatts of power, which is in the range of what several million American homes use. It would include a 24 gigawatt-hour battery system that SpaceX says would be the largest in the US. The campus would be dry-cooled with no evaporative spray, and SpaceX says it would use no industrial water. The company expects about 5,500 construction jobs and 1,000 permanent jobs, but the project still needs approval from Cochise County. - Texas: about 444 acres near the Port of Brownsville, with its own power generation. SpaceX says the project has already created more than 3,000 construction jobs and will employ more than 500 people once running.

**Why so much talk about "community benefits"**

Data centers use huge amounts of power and water and have become a flashpoint in many US communities. SpaceX devoted much of its announcement to local payoffs. It pledged $220 million to expand water and wastewater systems for Brownsville and Cameron County, with the city keeping ownership. In Arizona, it says it will hand $3.6 billion worth of grid upgrades to the local electric cooperatives at no cost, and projects that cooperative members' bills will fall 10% to 40% for the life of the project. Those arrangements are still "subject to final negotiations" with the co-ops.

The pushback is real. The Houston Chronicle reports that the Texas land was de-annexed by Brownsville and then annexed by the city of Starbase, and that on Nov. 4, less than a week earlier, the Brownsville City Commission unanimously approved a 90-day moratorium on new data centers. A representative of a local environmental justice group said residents fear losing access to water and power.

**What it means for you**

First, the AI race now runs through who can build power-plant-sized computing sites. A rocket company committing tens of billions of dollars to supercomputers shows that computing power is being treated as core infrastructure, on par with launch capacity. Second, promises like lower power bills and zero industrial water use are company plans, not results; they depend on approvals and on how the sites actually run. Third, the AI tools people use every day are backed by real electricity and water, and fights like Brownsville's over local data centers are likely to become more common.
