SpaceX plans more than $74 billion for two AI supercomputing campuses
SpaceX plans to invest more than $74 billion across two artificial intelligence supercomputing campuses, with $24 billion for Starbase in Texas and $50 billion for a new site in Arizona.
The announcement came on November 12, 2026, marking a significant shift for the company known primarily for rocket launches. The timing is crucial as AI has reportedly become SpaceX's primary revenue source, surpassing its space exploration activities.
The Texas project at Starbase will be built on a 444-acre site with its own gas-fired power plant, generating between 708 and 748 megawatts.
Arizona's massive scale
The Arizona campus in Cochise County represents the larger investment, spanning 747 acres with capacity for up to 6 gigawatts across nine buildings. Unlike the Texas site, it will eventually connect to local electric cooperatives and uses dry cooling methods without industrial groundwater.
Revenue driving the shift
The investment aligns with SpaceX's changing revenue streams, with AI accounting for over half of the company's third-quarter 2026 earnings. Anthropic, the AI lab behind Claude models, reportedly contributes roughly one-third of that AI revenue, while Google has signed a $920 million monthly agreement for computing services.
The Google deal alone works out to more than $11 billion over a full year.
Market and approval hurdles
SpaceX's June 2026 public listing under ticker SPCX means these spending decisions now face shareholder scrutiny. Both campuses still require local approvals, with votes on tax abatements scheduled for December 9, 2026, alongside a public hearing.
The investment signals SpaceX's commitment to AI as a core business rather than a temporary venture, though the company remains dependent on a few large customer relationships. The power strategies differ significantly between sites, with Texas going fully off-grid while Arizona eventually connects to local utilities.
