Inside TeraFab: Elon Musk’s $119 Billion Bet to Build the AI Chip Factory for Tesla, SpaceX and Orbital Compute

TeraFab has moved from Elon Musk’s audacious chip vision to a $16.8 billion first-phase project in Texas, with public filings pointing to a $119 billion four-phase buildout. NexusWild examines Intel 14A, High-NA EUV, AI5, AI6, orbital compute, power, economics and execution risk.

What to know

Texas and SpaceX confirmed an initial TeraFab phase in Grimes County requiring more than $16.8 billion of capital from SpaceX and Tesla and expected to create at least 3,000 jobs.
Texas incentive filings describe four planned phases and an estimated combined investment of $119 billion; that figure is a project estimate rather than fully deployed capital.
SpaceX says the completed TeraFab campus is planned to exceed 100 million square feet and combine logic, memory, advanced packaging and testing.
Tesla broke ground in April 2026 on a roughly $3 billion research fab at Giga Texas intended to test manufacturing ideas at a few thousand wafers per month.
Musk says TeraFab plans to use Intel 14A. Intel says 14A uses RibbonFET 2 and PowerDirect and targets 15% to 20% higher performance at the same power or 25% to 35% lower power at the same performance versus Intel 18A.
Intel and ASML said on September 7, 2026 that Intel had processed more than one million wafers using High-NA EUV across certification, R&D and production activities, strengthening the process ecosystem relevant to 14A.

TeraFab figures are explicitly separated between official first-phase commitments, public incentive filings, analyst estimates and long-term statements by Elon Musk or project materials.

TeraFab is now a real Texas industrial project, not just an Elon Musk presentation. The confirmed first phase exceeds $16.8 billion, public filings describe four phases totaling about $119 billion, and Intel 14A gives the plan a credible leading-edge process path. The harder question is whether Tesla and SpaceX can turn a 100-million-square-foot vision into competitive chips, memory and packaging at yields that justify the capital.
