SpaceX is preparing one of the largest single bets on AI infrastructure ever disclosed by a private company, committing $55 billion to a Texas chip facility called TerraFab and signaling the project could grow to as much as $119 billion if later phases are built. The numbers surfaced in a public hearing notice filed in Grimes County, Texas, attached to a request for tax breaks on the development.
"They're going to commit $55 billion to this Texas AI chip plant. And that could hit $119 billion if some of the laser phases get built out," Jaeden Schafer said on the AI Chat Daily podcast, calling the disclosure "absolutely massive" for a company still pouring cash into Starship.
The TerraFab spend slots into a broader compute target Elon Musk laid out in March, when he said his orbit of companies would aim for 200 gigawatts of what he termed "Earth compute" and up to one terawatt of space compute. "It's wild that we have to differentiate the two there," Schafer said on the show, underscoring how quickly the AI build-out has expanded beyond conventional terrestrial data centers.
Key facts
- 01SpaceX has committed a $55 billion base investment to TerraFab, a Texas AI chip plant, with potential to reach $119 billion across later phases.
- 02The figures appear in a public hearing notice filed in Grimes County, Texas, tied to a request for tax breaks on the project.
- 03The build-out supports Elon Musk's March target of 200 gigawatts of 'Earth compute' and up to one terawatt of space compute.
- 04SpaceX has leased its first Memphis Colossus data center, originally built for xAI, to Anthropic, while a Colossus 2.0 handles internal workloads.
Unlike the hyperscalers funding their AI plants from public balance sheets, SpaceX is a private, cash-generating business leaning heavily on Starlink revenue. Layering tens of billions of dollars of fab capex on top of an active Starship program puts unusual strain on internal cash flow, even before the optional phases that would push the project past the $100 billion mark.

The Grimes County filing matters because it gives outside investors and rivals a rare hard number on Musk's AI ambitions. Tax-break hearings require specific capital commitments, and the document ties SpaceX's name directly to a chip fabrication footprint in Texas — a state already courting AI manufacturing with incentives.
SpaceX is also moving to wring revenue out of compute it has already built. The first Colossus supercomputer, originally constructed in Memphis for xAI, has been leased to Anthropic, while a follow-on Colossus 2.0 handles xAI's own training workloads. The arrangement turns a sister company's idle capacity into a recurring contract with one of xAI's most direct rivals.
Schafer flagged the maneuver as a sign Musk's team is treating AI infrastructure as a financial asset class, not just a cost center. "I know that they're doing some smart things financially," he said, pointing to the Anthropic lease as a way to offset the eye-watering TerraFab bill.
The strategic question is whether SpaceX can sustain parallel mega-projects — Starship, Starlink expansion, the Memphis Colossus footprint and now a multi-phase Texas fab — without tapping outside capital on terms that dilute Musk's control. With $55 billion committed and another $64 billion of optional spend penciled in, TerraFab alone now rivals the announced AI capex of any single hyperscaler, and it is being underwritten by a privately held rocket company.
