Then there is advanced packaging, the facilities that stack HBM onto processors using 2.5D and 3D integration. These run $2 to $3.5 billion per phase, and TeraFab would need tens to hundreds of them.
The Terafab facility is projected to become the largest semiconductor manufacturing plant globally, significantly enhancing domestic chip production. The initiative aligns with the goals established by the CHIPS Act of 2022, which has prompted ...
It comes amid intensifying national efforts to reshore semiconductor manufacturing to the United States, driven by the CHIPS and Science Act signed into law in 2022, which allocated $52.7 billion in subsidies and incentives to domestic chip production. TSMC, Intel, and Samsung have all broken ...
For Europe and Spain, this movement ... the well-known "Chips Act", with the aim of increasing its share of global production and reducing dependence on Asia and the United States....
When Elon Musk unveiled plans for a new semiconductor manufacturing facility he called 'Terafab', he promised it would be the 'most epic chip-building exercise in history.' However, industry experts are doubtful that Musk can actually execute on the scale and scope he described, which would require up to $13 trillion in capital spending to build 140-360 new chip factories.
Musk's TeraFab dream meets Nvidia reality check on chip manufacturing limits
By vertically integrating chip production, Musk can ensure a reliable supply of the specialized semiconductors needed to push the boundaries of self-driving capabilities. Musk’s vision for Terafab includes powering a network of satellite-based data centers, which could potentially render traditional, land-based data centers obsolete.
The goal of Terafab is to produce 1 terawatt of computing power annually, while the current global annual output of AI computing power is about 20 gigawatts. That is to say, Terafab's goal is 50 times that amount. Musk's logic is straightforward - if Samsung, TSMC, and Micron expand production at full capacity, he is willing to "buy all the chips".
That’s what 80% of Terafab produces. Not chips to compete with TSMC on Earth.
The CHIPS and Science Act aims to bring manufacturing back to the U.S. by offering incentives to chipmakers. That’s brought new investments from TSMC, Intel, and Micron, plus projects like TSMC’s Arizona fabs and Elon Musk’s private Terafab ventures.
On March 23, 2026, Reuters reported that CEO Elon Musk said the day before that Tesla, Inc. (NASDAQ:TSLA) and SpaceX aim to establish two advanced chip factories in Austin, Texas, as part of the “Terafab” project.
Terafab will pursue 2-nanometer process technology — the most advanced node in the world, one that TSMC is only now beginning to produce at scale.

Elon Musk introduced his ambitious Terafab vision last week, aiming to produce a staggering terawatt of computing capacity annually. In contrast, the world’s current AI computing capacity is only around 20 gigawatts—about 2% of Musk’s projected needs.

After criticizing leading chipmakers for slow capacity expansion and claiming his companies need 100 – 200 billion AI processors annually, Elon Musk last week unveiled
Obviously, building an entire industrial AI-driven space economy would be a massive undertaking, and that is why Terafab will be required to meet those ambitions.
It’s less about building more factories and more about making the ones they have work better. There’s also a big emphasis on tighter software-hardware integration right from the start, aiming to dodge post-delivery fixes and recalls—even as the broader economy keeps everyone guessing.
Elon Musk, CEO of Tesla, announced in mid-March that he would launch the Terafab megafab project within seven days, and on March 21 confirmed that the facility will be built in Austin, Texas. While many remain skeptical, industry forum SemiWiki offers an alternative perspective.
The bank estimates that developing an initial 100,000 wafer-per-month capacity could require more than $60 billion in capital expenditure. Even at full utilization, Terafab’s production costs are expected to exceed those of TSMC’s advanced nodes, with wafer costs potentially 30% to 50% higher.
Analysts note that building a competitive semiconductor foundry from scratch is among the most complex industrial challenges. Market leaders such as TSMC and Samsung Electronics benefit from decades of accumulated expertise, vast capital investment and deeply embedded supply chain ecosystems. In contrast, Terafab would begin with limited manufacturing experience and lack critical infrastructure, including advanced electronic design automation tools and established intellectual property libraries
