From Darkness Unto Light, 20 May 2026 Update – Part 1

MOVE 1: SpaceX filed permits for a $55 BILLION chip fabrication facility in Texas. A TERAFAB — the largest semiconductor plant ever proposed on American soil. They’re not building satellites anymore. They’re building the hardware for an entirely new global infrastructure.

Tesla Breaks Ground on Terafab Chip Facility at Giga Texas

Facility 2 (Space-grade): Focused on high-powered AI chips designed for orbital data centers — essentially AI satellites in space, supporting what is expected to be a next-generation Starlink intelligence layer. The target process node is 2 nanometers — putting Terafab in direct competition with TSMC's most advanced production lines.

Terafab serves all three companies. AI5 chips for Tesla FSD and Optimus. D3 chips for SpaceX orbital data centers. Potentially custom inference silicon for xAI Grok deployment.

Starship V3 Explained: What the Taller Rocket, Raptor 3

On March 21, 2026, Musk outlined the Terafab project in Austin, Texas: a joint SpaceX, Tesla, and xAI initiative targeting one terawatt of AI processor production annually. That would be roughly 50 times the current combined global production ...

Inside Elon Musk’s Terafab - by Ana Levine - E1 Ventures

Intel’s own materials on advanced packaging underline how much of modern compute capability now depends on combining multiple dies within a single package. Performance, bandwidth, thermals, and density increasingly depend on packaging and integration choices rather than on logic scaling alone. That is one reason the repeated pairing of “logic, memory, and packaging” in the Terafab discussion is significant.

Tesla's Terafab Dream

Design happens at fabless customers, memory is made at separate fabs (Micron, Samsung, SK Hynix), and advanced packaging and test are typically done at OSAT facilities or dedicated packaging sites. Terafab's claim is that design, lithography, fabrication, memory production, advanced packaging, and testing all happen at a single site.

Elon Musk lays out Terafab AI chip project plan | Reuters

Musk's SpaceX, its xAI ​unit and Tesla will build two advanced chip factories at a sprawling facility in Austin, one to be used in ‌Tesla vehicles and Optimus humanoid robots, and another designed for AI data centers in space.

Tesla generated nearly $890M from SpaceX and xAI deals

Musk’s companies have long maintained overlapping financial relationships through investments, partnerships, shared employees, and common investor networks. Tesla and SpaceX are also collaborating on a semiconductor manufacturing facility Musk has referred to as “Terafab.”
