Musk Confirms Talks with TSMC on Texas Chip Fab Collaboration
nashnova research
Elon Musk confirmed on October 2 that his chip venture Terafab is in discussions with TSMC over a Texas factory project; a deal would recast Terafab from chipmaker to anchor customer, while giving TSMC the demand guarantee it needs for a second U.S. site.
What exactly is on the table?
Musk replied to a report on X: "Just talking, but maybe something will come of it."
According to Culpium, citing anonymous sources, the likeliest structure is: TSMC builds and operates a new fab, with SpaceX or Terafab taking an equity stake, signing a volume-purchase agreement, or both.
This means → Terafab would not make chips itself — it would hand TSMC the money and the orders in exchange for guaranteed supply. Buying a seat, not driving the car.
Why does TSMC need this deal?
TSMC is evaluating a second U.S. manufacturing site; the Texas campus plan is at an early stage with no investment decision made.
Two core concerns: whether Congress will extend the advanced-manufacturing investment tax credit, and whether demand is sufficient to fill the lines.
In plain terms = building one advanced wafer fab — a factory that turns silicon into chips — costs tens of billions of dollars. TSMC needs to know: subsidies won't vanish mid-build, and orders will keep the lines full.
Market rumors put the Texas campus at up to six advanced-node fabs, but the figure is unconfirmed.
What does Musk get out of it?
Terafab lacks wafer-fab operating experience — a TSMC partnership would shift its role from manufacturer to large-scale anchor customer.
This means → Musk secures stable chip supply while sidestepping the technical risk of building his own production capacity.
Terafab was announced jointly by Tesla and SpaceX in March 2026 with an initial investment of roughly $25 billion; Intel joined in April. Full-phase investment ranges from $55 billion to $119 billion per county-level filings.
What questions are still open?
Texas is not TSMC's only option — the company has reportedly been in contact with Singaporean officials about other overseas capacity plans.
Neither side has addressed how the partnership would affect Intel's role in the Terafab project — a key point to watch as talks progress.
Phase one is sited in Grimes County, northwest of Houston, with a $16.8 billion budget and construction set to begin in December.
