Elon Musk said SpaceX may rename its AI-focused unit SpaceXAI to SpaceXSI, describing SpaceX as a “super intelligence company.” He also said SpaceX and Tesla are discussing Terafab cooperation with TSMC, but the talks are preliminary and no agreement or rebrand has been confirmed.
Elon Musk has said SpaceX may rename its AI-focused unit SpaceXAI to SpaceXSI, while describing SpaceX as a “super intelligence company.” The possible name change remains a proposal, not a confirmed rebrand; separately, Musk said SpaceX and Tesla are in discussions with TSMC about the companies’ Terafab semiconductor project.
Musk’s remarks about the name followed a September 22 directive from President Donald Trump calling for artificial intelligence to be referred to as “super intelligence,” or SI, and urging the U.S. government to adopt the terminology. Musk expressed willingness to use the new label for SpaceX’s AI-focused unit. He also posted that the companies’ talks with TSMC were “just discussions, but something may come of it.” Neither statement confirms a completed rebrand or a deal with the chipmaker.
The discussions with TSMC concern Terafab, a planned joint project involving SpaceX and Tesla. The project is intended to produce at least one terawatt of AI compute per year for applications including Optimus robots, self-driving cars and space-based AI data centers. The project is being developed in Grimes County, Texas, and its first phase is reported to involve an initial investment of $16.8 billion; the full buildout could cost more than $100 billion.
Intel joined the initiative in April 2026, with plans to contribute its 14A process technology and advanced packaging capabilities. TSMC’s potential participation has not been finalized. Preliminary reporting says the company is considering operating a Texas fab, with Terafab potentially serving as a major customer through an equity investment, purchase commitments or both. Those options remain under discussion, rather than settled terms.

SpaceXSI? Musk Floats a New Name as Terafab Talks Expand
Elon Musk said SpaceX may rename its AI-focused unit SpaceXAI to SpaceXSI, calling SpaceX a “super intelligence company.” Separately, SpaceX and Tesla are discussing TSMC’s possible role in Terafab. Neither a rebrand nor a chipmaker deal has been confirmed.
Planned annual AI compute target
Reported initial investment
Reported project cost estimate
Reported 14A and packaging role
01 / Two separate developments
A Name Change Meets a Chip-Building Plan
Musk’s remarks link a possible terminology shift with a separate industrial project. The status of each matters: an expressed willingness is not a company decision, and early talks are not a supplier commitment.
SpaceXAI → SpaceXSI
Musk said the AI-focused unit may take the new name after President Trump promoted “super intelligence” as a term for AI. No formal announcement or timetable has been provided.
Terafab discussions
SpaceX and Tesla are talking with TSMC about a possible role. Musk described the exchange as “just discussions,” with no deal, investment or fab location settled.
Terafab ambition
The SpaceX–Tesla project targets at least one terawatt of AI compute per year for Optimus robots, self-driving cars and space-based AI data centers.
02 / Policy & industry
Two Stories, One Terminology Shift
The proposed label follows a White House push. Terafab’s scale puts financing, suppliers and production plans in focus.
Trump’s “SI” push
President Donald Trump called for government adoption of “super intelligence” in place of “artificial intelligence.” Reporting also describes a proposed Super Intelligence Force initiative to connect the federal government with industry. Its structure and scope have not been detailed here.

A project still taking shape
Wccftech reports that Terafab’s first phase is under construction. Intel joined in April 2026, with plans to contribute its 14A process technology and advanced packaging capabilities. TSMC’s potential participation remains exploratory.
Reported plans and estimates; figures are not operational results or finalized budgets.
03 / How the proposal could progress
From Talk to a Verified Decision
The next useful signals are official company updates. Until then, treat both the name and supplier question as open.
Proposal voiced
Musk signals willingness to use “SpaceXSI.”
Company decision
An official SpaceX statement would confirm a rebrand and effective date.
Supplier terms
SpaceX, Tesla or TSMC could disclose a commercial or investment agreement.
Build & output
Financing, construction and production updates would clarify the project timeline.
04 / What is known today
Confirmed, Reported, Still Unsettled
A quick status check helps separate public remarks and reported plans from completed actions.
| Question | Current status | What remains open |
|---|---|---|
| SpaceXAI renamed SpaceXSI? | ~ Proposed | No formal rebrand announcement or effective date. |
| TSMC joining Terafab? | ~ In discussion | No confirmed agreement, investment, fab location or schedule. |
| Intel involved? | ✓ Reported participant | Planned contribution: 14A process technology and advanced packaging. |
| One terawatt of annual compute? | ~ Project target | Planned capacity, not current production or a verified output timeline. |
05 / Key questions
What Readers Should Know
Has SpaceX officially changed the name?
No. Musk expressed willingness to consider SpaceXSI, but no completed rebrand or effective date has been confirmed.
What did Musk say about TSMC?
He called the SpaceX and Tesla talks “just discussions,” adding that something may come of them. That does not confirm a deal.
What is Terafab intended to do?
The planned project aims to produce at least one terawatt of AI compute per year for robotics, self-driving vehicles and space-based data centers.
How much could a Texas fab cost?
Reporting puts the first phase at $16.8 billion and the full buildout above $100 billion. Those are reported plans and estimates, not final costs.
A Name Change Meets a Chip-Building Plan
The proposed SpaceXSI name would align Musk’s company with the terminology Trump has promoted, but the immediate practical significance lies in the two separate developments: a possible corporate rebrand and talks that could expand the suppliers involved in Terafab. Neither development is confirmed as a completed action, so readers should distinguish Musk’s stated willingness from a formal company announcement, and early talks from a TSMC commitment.
If TSMC takes part, it could bring another major semiconductor manufacturer into a project designed to supply computing capacity for SpaceX and Tesla’s AI-related ambitions. But the project’s scale and potential cost also make its financing, production plans and supplier roles consequential. A Texas facility could add U.S.-based capacity, while also exposing TSMC to higher costs: the company has said Arizona wafers cost 30% to 40% more than wafers produced in Taiwan. That comparison concerns Arizona production and Taiwan-based production; it does not establish the cost of any proposed Texas fab.

Trump’s SI Push and Terafab’s Suppliers
The naming discussion followed Trump’s September 22 call for government adoption of “super intelligence” in place of “artificial intelligence.” The supplied reporting also says Trump announced a proposed Super Intelligence Force initiative to connect the federal government with the wider industry. Musk’s SpaceXSI suggestion is a response to that terminology shift, but no formal rebranding announcement or implementation timetable has been provided.
Terafab is the industrial backdrop to Musk’s separate comments about TSMC. SpaceX and Tesla are pursuing a large-scale chip and computing project, with Intel already named as a participant. Wccftech reports that Terafab’s first phase is under construction in Texas and that the project’s projected capacity and costs refer to planned targets, not current output. The possibility of TSMC joining would add another potential supplier, but the available details describe exploratory discussions, not an agreement.
“Just discussions, but something may come of it.”

No Rebrand or TSMC Deal Yet
It is not clear whether SpaceX will formally rename SpaceXAI, when any change would take effect, or whether the unit currently uses that name in official company materials. Musk’s stated willingness does not establish that a decision has been made. The precise structure and scope of the proposed Super Intelligence Force are also not detailed in the information available here.
For Terafab, TSMC has not been confirmed as a participant. No final agreement, investment amount, fab location or construction schedule has been disclosed. The reported figures for capacity and total project cost describe plans and estimates, not operational results; the companies have not provided a completed timeline for production in the details cited.

Formal Decisions Will Set the Timeline
The next concrete indicators would be an official SpaceX announcement confirming whether it will adopt SpaceXSI, and a direct update from SpaceX, Tesla or TSMC on whether their discussions lead to a commercial or investment agreement. Until then, the proposed name and TSMC’s possible role should be treated as unconfirmed developments.
Further details about Terafab’s construction, financing, production capacity and the contributions of Intel and any additional partners would clarify how the project is intended to proceed. The reported plans establish its ambitions, but they do not show when the facility will begin producing chips or how much of its proposed annual compute target it will reach.
