Intel said on X this morning that it is joining Elon Musk’s Terafab project with SpaceX, xAI and Tesla, putting the chipmaker into a $25 billion Austin plan that Musk first unveiled last month. The move ties Intel stock to one of the most audacious semiconductor bets now on the table: a vertically integrated mega-facility on the north campus of Giga Texas meant to cover design, lithography, fabrication, memory, advanced packaging and test under one roof.
Intel said its ability to design, fabricate and package ultra-high-performance chips at scale will help accelerate Terafab’s goal of producing 1 TW/year of compute. That is the pitch Musk has been making since he introduced the project, and the scale is staggering even by chip-industry standards.
Musk told investors last month that Tesla would have to build its own fab because even the best-case supply from TSMC and Samsung was not enough to cover the AI5, AI6 and Optimus chips the company needs. Tesla already has a $16.5 billion AI6 deal with Samsung and a TSMC relationship for AI5, but Musk has argued that still leaves too much demand uncovered. Tesla, for its part, has never made a wafer in its life.

Intel’s involvement matters because leading-edge chip fabs are brutally hard to stand up. TSMC, Samsung and Intel have each spent a decade and tens of billions of dollars building that kind of capability, and Intel’s own 18A process node is now in volume production. The company has been trying to land marquee foundry customers since Pat Gelsinger first pitched IDM 2.0, and its foundry unit still needs customers to justify the capital spending behind it.

That is the friction inside the Terafab story. Musk has described the project as a way to build a self-contained manufacturing stack, but the announcement now folds in a company that has spent years trying to persuade outsiders to trust it with their chips. Whether Terafab becomes a clean demonstration of Musk’s vertical-integration vision or another expensive test of just how hard sub-2nm manufacturing really is will depend on whether the partners can turn the idea into a working line, not just a headline.
