Intel to Make Terafab Chips for Tesla, SpaceX & xAI

Intel announced  that it would join the Terafab project, committing to design, fabricate, and package chips for the Austin facility. Lip-Bu Tan, Intel’s chief executive, met with Mr. Musk at Intel’s campus over the weekend in what amounted to a formal acknowledgment of how the project has been recast: not as a homegrown manufacturing venture, but as a co-anchored expansion of Intel’s foundry business, with Tesla and SpaceX serving as guaranteed anchor customers.

“Intel’s capabilities in design, fabrication, and packaging will help accelerate Terafab’s goals,” the company said in a statement — language that, to semiconductor industry veterans, describes something closer to a foundry partnership than a supplier relationship.

The shift reflects the practical realities of advanced chip manufacturing, an endeavor that typically requires a decade or more and upward of $20 billion to establish, along with deep institutional expertise that cannot be assembled quickly. Tesla has never produced a semiconductor wafer. Intel has been doing so for more than 50 years.

Intel’s 18A process node, at roughly 1.8 nanometers, ranks among the most advanced in commercial production today, and the company’s packaging capabilities are regarded as world-class. What Tesla, SpaceX, and xAI bring to the table, analysts said, is something Intel has been urgently seeking: demand, capital, and the political symbolism of building artificial intelligence infrastructure on American soil.

For Intel, the partnership amounts to the most significant validation of its foundry strategy since Mr. Tan assumed the chief executive role in March 2025. Intel Foundry recorded an operating loss of $10.32 billion last year on revenue growth of just 3 percent, and the unit has struggled to attract the marquee customers needed to justify its continued capital expenditures. Securing Mr. Musk’s entire compute ecosystem — spanning autonomous vehicles, humanoid robotics, satellite data centers, and AI model training — provides exactly the demand signal the business has been trying to generate.

For Tesla, the arrangement is more complicated. The company has existing chip agreements with Samsung for its AI6 processors and with TSMC for AI5, and Mr. Musk framed Terafab explicitly as a means of achieving supply independence. He told investors last month that Tesla “had to” develop its own fabrication capabilities because external partners could not guarantee sufficient volume.

The company is also navigating a crowded strategic agenda. Tesla has seen vehicle sales decline in recent quarters, lost a number of senior executives, and is simultaneously ramping production of two unproven products — the Cybercab robotaxi and the Optimus humanoid robot — that together represent a significant test of the company’s manufacturing capabilities.

The divergence between Mr. Musk’s March announcement and the arrangement now taking shape is not unusual for a project of this scale. What he described as an independent semiconductor operation appears to have evolved, at least for now, into something more pragmatic: a partnership with the one American company that has the technology to make such a facility viable.

Industry analysts noted that the revised structure, while less dramatic than the original vision, is arguably more achievable.

“What’s being built is a co-anchored Intel foundry expansion,” said one semiconductor analyst, who spoke on the condition of anonymity because of ongoing business relationships with the companies involved. “That’s a real thing. The original announcement was not.”
