Elon Musk said SpaceXAI would be renamed SpaceXSI, adding a proposed branding change to the still-unresolved TeraFab discussions with TSMC. The new detail since Saturday’s coverage is a stated plan, not a completed rename, an agreement with TSMC or delivered chip capacity, DatacenterDynamics reported.
Musk again confirmed that SpaceX and TSMC have discussed TeraFab but did not describe TSMC’s role or announce terms. His reply, as Tom’s Hardware reported, was: "Just discussions, but something may come of it".
Saturday’s report covered Musk’s confirmation of the talks and the absence of an announced deal. Intel had already announced it would join TeraFab, but its participation did not establish a factory or production capacity.
What role could TSMC have in TeraFab?
Musk has not said what the discussions cover. DatacenterDynamics summarized journalist Tim Culpan’s reporting about one possible arrangement: TSMC could own and operate a Texas chip factory, while SpaceX invested or committed to buy chips. Culpan also reported that other arrangements were being considered. None has been announced as an agreement.
DatacenterDynamics and Tom’s Hardware reported that TSMC had not publicly commented on the discussions. The reporting supports that Musk confirmed talks; it does not establish that TSMC will participate or what it would do.
Owning or operating a factory, investing in it and agreeing to purchase its output would be different commitments. The available reports do not say which, if any, has become a formal proposal between the companies.
Why could TeraFab matter for AI compute?
TeraFab has been presented as a way to address chip needs across Musk’s companies, including their AI work. A manufacturing or supply agreement could therefore be relevant to those plans, but the talks themselves do not add capacity: no chips or additional compute capacity from TeraFab have been reported as delivered.
DatacenterDynamics describes TeraFab as a $16.8 billion project. That is a reported project figure, not proof that the money has been invested or that manufacturing has begun. The reports do not establish production volumes, a schedule or the technology the factory would use.
Intel has announced it is joining the project, making it another named participant alongside the potential TSMC role discussed in reporting. The available accounts do not define Intel’s production responsibilities or explain how its role would relate to TSMC’s.

DatacenterDynamics also reported that Grimes County commissioners approved three proposals for a 100% property-tax abatement in June 2026, by a 4–1 vote. Those approvals are not evidence that a chip factory is operating or producing capacity.
What would confirm a TeraFab chipmaking deal?
Musk first floated the TeraFab idea at Tesla’s annual shareholder meeting in November 2025, according to DatacenterDynamics. In March 2026, he confirmed plans for a semiconductor plant; later, Intel announced it was joining. Those steps document plans and announced participation, not completed production.
The proposed SpaceXSI name change does not answer questions about the factory. The reporting offers no evidence that the new name would change SpaceXAI’s technology, organization, products or computing resources.
A public agreement specifying TSMC’s role would clarify whether the talks became a partnership. Facility and construction details, a production timeline and evidence of chip output would be needed to establish whether TeraFab adds manufacturing capacity. Those details remain unresolved.
