What Is Elon Musk’s Terafab Project and Why Is ASML Involved?

TLDR

• Elon Musk will virtually attend a closed-door ASML employee conference to discuss Terafab, a SpaceX-Tesla chip venture
• Terafab plans to build a U.S. chip factory costing at least $55 billion to produce 2-nanometer chips
• ASML confirmed it will collaborate on the initiative alongside other companies in the semiconductor supply chain
• ASML shares dropped 6.55% on Friday, closing at $1,641.74, in line with a broader tech sector sell-off
• Analysts hold a Strong Buy consensus on ASML stock with an average price target of $1,905.25, implying 16.05% upside

Elon Musk will virtually attend a closed-door technology conference hosted by ASML Holding, the Dutch chip-equipment company, to discuss his Terafab chipmaking project, according to Bloomberg.

Terafab is a joint venture between SpaceX and Tesla, unveiled in March 2026. The project aims to build a chip factory in the United States at a cost of at least $55 billion.

The factory would produce 2-nanometer chips, which are among the most advanced semiconductors currently available. Musk wants the project to eventually support a terawatt of computing power per year.

ASML invited Musk to speak to its employees about his vision for AI, robotics, space, and semiconductor manufacturing. A company spokesperson confirmed the appearance to Bloomberg.

What Is Terafab and Why Does It Matter?

Terafab is designed to supply chips for Tesla’s robotics programs, SpaceX’s space data centers, and Musk’s broader artificial intelligence operations. The venture represents a push by Musk to reduce his companies’ dependence on existing chip suppliers.

Right now, companies like Taiwan Semiconductor Manufacturing and Samsung produce the most advanced chips in the world. Terafab would aim to compete directly with those foundries, though experts note that matching their scale, yield, and manufacturing expertise would be extremely difficult.

ASML plays a central role in this picture. The company makes the lithography machines that are required to manufacture the most advanced chips. No chip factory at this level can operate without them.

ASML confirmed that “many companies, including ASML, will collaborate on this initiative,” suggesting Terafab is shaping up as a broader industry effort rather than a solo Musk project.

ASML Stock Falls as Tech Sector Sells Off

ASML shares dropped 6.55% on Friday and closed at $1,641.74. The decline came alongside a wider sell-off in the tech sector and was not specific to the Terafab news.

Despite the drop, Wall Street analysts remain positive on the stock. ASML currently holds a Strong Buy consensus based on six analyst ratings.

The average price target from those analysts is $1,905.25. That implies a potential upside of 16.05% from Friday’s closing price.

For ASML, Terafab could eventually represent a major new source of demand for its high-end equipment. The company already counts Taiwan Semiconductor and Samsung among its key customers.

ASML recently became the most valuable stock in European market history, driven by rising demand for its machines as AI spending continues to grow.

For Musk, the ASML conference appearance is the latest step in positioning Terafab as a credible industrial project. The $55 billion factory, if built, would rank among the largest semiconductor investments ever made in the United States.

No timeline has been given for when construction on the Terafab facility would begin.
