Elon Musk plans U.S.-based AI chip manufacturing initiative with estimated $13 trillion investment

Elon Musk is exploring a massive initiative to build domestic advanced semiconductor manufacturing facilities in the United States to support AI data processing. This ambitious project, often compared to a U.S. version of TSMC, could require investments estimated at up to $13 trillion. This moves marks a significant pivot toward vertical integration for AI chips, following Musk's major ventures in EVs and space exploration.
Context
On March 21, 2026, Elon Musk unveiled a massive semiconductor initiative titled Terafab during an event in Austin, Texas. Musk described the project as "the most epic chip-building exercise in history by far," aiming to achieve vertical integration for Tesla, SpaceX, and xAI. While the headline figure of $13 trillion (2,000 trillion yen) stems from early high-end estimates of the total required investment to overhaul global AI infrastructure, specific project costs for the Texas facility are currently estimated between $20 billion and $40 billion.
The initiative is driven by Musk's assessment that existing leaders like TSMC and Samsung cannot expand capacity fast enough to meet his companies' robotics and AI demands. The Terafab facility plans to produce two specialized chip families: edge-inference processors for Tesla’s Optimus and Robotaxi fleets, and high-power chips for SpaceX’s orbital data centers. Musk warned that without this in-house manufacturing, the U.S. faces a "limiting factor" in electrical power and hardware availability that could stall AI deployment relative to competitors like China.
