Elon Musk said Tesla is considering building a semiconductor manufacturing facility valued at about $25 billion, as the company looks to secure a long-term supply of chips for its expanding artificial intelligence operations.
In posts published over the weekend on X Corp., Musk referred to the proposed project as “Terafab,” describing it as a large-scale fabrication plant that could produce the processors needed for Tesla's self-driving systems, data-center infrastructure and robotics development.
Musk said construction could begin as early as March 21, though Tesla has not released a formal statement outlining the project's scope, timeline or financing.
Pressure From Growing AI Demand
Tesla has been rapidly expanding its computing capacity as it develops autonomous driving software and trains increasingly large artificial intelligence models. The company also plans to deploy its Optimus humanoid robot in industrial settings in the coming years.
Meeting that demand through traditional semiconductor supply chains could prove difficult, Musk suggested, given the long timelines typically required to build and ramp up advanced chip fabrication plants.
Challenging the Traditional Foundry Model
Advanced chips used in artificial intelligence systems are currently produced mainly by large contract manufacturers such as Taiwan Semiconductor Manufacturing Company and Samsung Electronics.
These companies generally require several years to bring new fabrication plants online, from groundbreaking to high-volume production. Musk has said such timelines could slow Tesla's plans as the company increases investment in AI computing.
The proposed Terafab facility would aim to reduce that dependence by bringing more semiconductor production under Tesla's control.
Production Targets and Technology
Musk suggested the factory could eventually scale to roughly one million wafer starts per month, placing it among the largest semiconductor fabrication facilities in operation.
He also indicated Tesla might explore collaboration with other semiconductor manufacturers. In one post, Musk wrote that discussions with Intel regarding potential use of its upcoming 18A process technology could be “worth having.”
Industry Skepticism
Some analysts say building a leading-edge semiconductor fabrication plant would present major challenges for a company whose core business remains automotive manufacturing.
Dan Nystedt, a technology analyst who tracks the semiconductor sector, said the plan could face obstacles including recruiting experienced engineers, securing advanced equipment and achieving stable production yields at cutting-edge process nodes.
Constructing and operating a modern chip fabrication facility is widely considered one of the most complex undertakings in the technology industry, often requiring years of development and tens of billions of dollars in investment.
Even so, Musk has argued that deeper vertical integration may become necessary if Tesla's AI ambitions continue to grow.
