The lights shooting into the Austin sky on Saturday night weren’t aliens. They were Elon Musk doing what Elon Musk does best — staging an event so audacious that you can’t look away, even if you’re not sure you believe a word of it. Inside the defunct Seaholm Power Plant in downtown Austin on March 21, Musk officially launched Terafab — a joint venture between Tesla, SpaceX, and xAI to build what he calls “the most epic chip-building exercise in history by far.” The price tag: an estimated $20–25 billion. The goal: producing one terawatt of computing power per year, with 80% of it destined for space. ...

Seven words on X. That’s all it took to detonate the semiconductor world. On March 14, Elon Musk posted: “Terafab Project launches in 7 days.” Over 866,000 views within hours. And if Tesla actually pulls this off, it could be the most ambitious vertical integration play in the history of chip manufacturing. What Terafab Actually Is Think “Gigafactory, but for chips” — except Musk says it’s “like giga but way bigger.” Confirmed during Tesla’s January earnings call, Terafab would combine logic processing, memory storage, and advanced packaging under one roof. Full vertical integration at a scale that currently only exists at TSMC and Samsung. ...
