Elon Musk took the stage at the defunct Seaholm Power Plant in Austin tonight to officially launch the Terafab Project, a massive joint venture between Tesla, SpaceX, and xAI.
Musk described the initiative as the most “epic chip building exercise in history by far,” aimed at achieving total vertical integration of the AI supply chain. The project’s goal is to produce an unprecedented one terawatt of computing power annually within a single facility.
The Terafab is designed as a “comprehensive plant” that will house every stage of semiconductor production under one roof, including logic, memory, packaging, and testing. Musk highlighted that this approach allows for a continuous loop of testing and revising masks, a capability he claimed “doesn’t exist anywhere in the world.” This facility is the next step to becoming a “galactic civilization,” closing the gap between today’s chip production and the massive demand of a future among the stars.
The scale of the project is driven by the need to harness power from the sun by sending 100 million tons of solar capture equipment into space every year. This requires the capability to launch millions of tons of mass into orbit to support solar-powered AI satellites and millions of Tesla Optimus robots. Musk noted that Optimus alone will require 100-200GW of chips, while terawatts will be needed for the satellite arrays—a demand that exceeds the capacity of all current and projected chip manufacturers combined through 2030.
Musk explained that while the company will continue to buy Nvidia chips, the Terafab is essential to reach a scale of “amazing abundance.” He concluded by painting a picture of a future where humanity eventually moves “beyond the moon, beyond Mars, and we sail through the rings of Saturn.” He stated that in an economy a million times the size of Earth’s current output, “if you can think of it, you can have it.”
Building a fab from scratch is often called a Herculean task because it involves more than just a building; it requires securing $20–$25 billion in capital and thousands of specialized engineers to manage over 2,000–5,000 individual processes required to make a single chip.
