Musk's Terafab Procures ASML EUV Equipment, 2029 Mass Production Target Emerges
nashnova research
ASML hinted on its earnings call that Musk's Terafab is now an EUV lithography customer, with first tool delivery in mid-2027 and mass production targeted for late 2029 — but ASML is simultaneously raising prices and rationing orders, making equipment supply the biggest wildcard for this brand-new chipmaking venture.
What is Terafab — and why is Musk building his own chips?
Terafab is a chip manufacturing project Musk formally announced in March 2026, with initial investment exceeding $15 billion. Tesla, SpaceX, and other companies are involved.
The site is in Grimes County, Texas. Phase-one investment stands at $16.8 billion; Texas filings suggest total multi-phase investment could reach $119 billion.
This means → Musk wants to stop relying on TSMC and Samsung for chips. The goal is to bring design, fabrication, memory, and packaging into a single campus — serving Tesla vehicles, Optimus robots, Cybercab, and even SpaceX's planned space data centers.
How did ASML "hint" at this customer?
On ASML's Q3 2026 earnings call, CEO Christophe Fouquet mentioned a brand-new customer whose name likely starts with "T" seeking lithography orders for 2029–2030. The market widely interprets this as Terafab.
Fouquet stressed the demand goes beyond one client: "We continue to see new customers in low-NA EUV — a mature version of extreme-ultraviolet lithography, the technology that etches circuits onto chips with ultra-short-wavelength light — especially in DRAM."
In plain terms = ASML is telling the market: Musk isn't the only one in line — the entire EUV demand pool is expanding, which sets the stage for the price hikes and order rationing that follow.
Is the production timeline realistic?
Analyst Tim Culpan reports Terafab will receive its first EUV tool in mid-2027, but the development fab shell won't be finished until late 2027.
SemiAnalysis projects the production fab will begin operating in late 2029 and ramp to volume by mid-2030. The plan calls for Intel 14A process technology, using both low-NA and high-NA EUV scanners.
Musk has proposed a "SpaceX-style" chip iteration model: 10 design iterations per year, far exceeding the industry's typical two-year cycle. But he admitted: "Frankly, I don't know how to make chips, but we'll figure it out."
This means → The timeline is extremely aggressive — equipment hasn't arrived, the building isn't done, yet the target is volume production in two and a half years. Whether this holds depends on the next question.
Why is ASML rationing orders and raising prices?
CFO Roger Dassen said ASML is deliberately not accepting orders for 2029–2030. The reason: it doesn't want to book some customers first, then tell long-standing partners "sold out." ASML will wait until demand is fully visible, then accept orders in one round.
At the same time, ASML confirmed for the first time that it has raised prices on its "most critical products." The increase will show up in average selling prices and margins starting in 2027, with full effect from 2028. CEO Fouquet called the pricing negotiation "unprecedented" and said customers showed "clear recognition" that "value across the ecosystem is shifting."
In plain terms = ASML holds all the cards — it is the only company on Earth that makes EUV lithography machines. That monopoly position lets it do two things at once: raise prices and choose whom to sell to.
How big is the equipment supply gap?
ASML expects to deliver roughly 65 low-NA EUV systems in 2026, up nearly 50% from 44 units in 2025.
But Dassen acknowledged that planned output for 2027–2028 "will not fully meet customer demand." The company is studying whether to push 2028 capacity expansion beyond 30%.
The new NXE:3800F processes 260 wafers per hour, up from 230 on the current 3800E, and will ship in limited volume in early 2027.
This reflects a core tension: more customers want EUV tools, but machine output can't scale fast enough. As a newcomer, Terafab's place in the queue is itself an open question.
Who makes Tesla's chips right now?
Samsung's Taylor, Texas fab currently produces Tesla's AI5 chips and holds a $16.5 billion contract for AI6 chips.
TSMC supplies the rest of Tesla's chip needs.
Intel joined Terafab as a manufacturing partner in April 2026, but the two sides have only a framework agreement — financial terms and IP arrangements are still under negotiation.
This means → Terafab is still a blueprint. Tesla's chip supply chain remains entirely dependent on Samsung and TSMC. Between "buying someone else's chips" and "making your own" lie at least three years and well over a hundred billion dollars.
