Musk Wants Tesla and SpaceX to Rethink Chip Manufacturing

what happened

GuruFocus reports that Elon Musk believes Tesla and SpaceX could eventually become unusually capable chip manufacturers by drawing on an existing strength: building machinery tailored to their own factories and products. Speaking by video at the X Takeover event near Tesla’s Gigafactory in Austin, Musk admitted that he does not currently know how to make microchips, but said the companies would learn how.

Musk’s broader point is that the manufacturing method itself could provide an edge. He said visits to competing sites had revealed little highly customized equipment, whereas Tesla and SpaceX have substantial experience developing specialized machines for their operations. That know-how, in his view, could help them improve the way chips are made instead of depending entirely on standard tools used across the industry.

The remarks add to Musk’s increasingly ambitious semiconductor plans. Earlier this month, he said Tesla and SpaceX intended to build and operate the proposed Terafab AI-chip complex on their own, while allowing for the possibility that TSMC could sublease part of it. When speculation suggested that TSMC might ultimately own and run the facility, Musk replied: “No, we will build and run the fab. Let there be ZERO doubt about that.”

Tesla and SpaceX already rely heavily on advanced semiconductors for autonomous-driving technology, AI training, robotics, communications and other compute-intensive uses. More internal production could give them greater influence over costs, supply and product architecture. The challenge is considerable: advanced fabrication demands exceptional precision, engineering expertise and capital, while foundries such as TSMC have developed those advantages over decades. Investors will be watching Terafab’s construction schedule, manufacturing partners, targeted process nodes, capital needs and whether custom equipment can produce better chip economics.

why it matters

The proposal is more ambitious than a conventional capacity expansion. Terafab could become an effort to build a proprietary manufacturing system around Tesla’s and SpaceX’s AI workloads, but the companies would face a substantial technological and execution gap.
