Terafab is rush-ordering chip tools in Japan, with a plan 40 times Rapidus’s wafer capacity
Japan’s Nikkei says a procurement team from Elon Musk’s Terafab chip project visited Japanese equipment makers early this month, placed orders due within months, and shared a long-term target of 1 million silicon wafers a month from 2032. Against Rapidus’s planned ~25,000 wafers a month, that is the “40 times” figure in Nikkei’s headline. None of that has been announced by Musk’s companies. It’s a reported plan, and the 2032 number was shared informally.

What Nikkei reported
Nikkei’s Japanese story went up at 5:00 Japan time on Monday, 9 Nov 2026, which was 3:00 p.m. ET / 12:00 p.m. PT on Sunday, 8 Nov 2026. Its headline says Terafab’s planned production volume is “40 times Rapidus,” that Musk’s Terafab procurement team made a secret trip to Japan, showed order plans to equipment makers and is pushing to get the fab started early. Rapidus is Japan’s government-backed company trying to make 2-nanometer chips in Hokkaido.
The free part of the article opens with a line from an executive at a Japanese supplier: “The biggest topic in the semiconductor industry right now isn’t Kioxia or Rapidus. It’s Elon Musk.”
The rest sits behind Nikkei’s paywall. Asia Business Daily’s English write-up of the report fills in the numbers (also consistent with other English summaries of the same Nikkei story). According to that summary, the long-term plan the team shared with equipment makers is 1,000,000 wafers a month from 2032, with about 700,000 of those for memory and more than 300,000 for logic chips. Procurement staff visited Japan early this month and started detailed talks on mass-production schedules. Some suppliers have already received orders with delivery dates just a few months out. One company representative told Nikkei: “It’s an unreasonable order, but we have no choice but to do what we can to meet it.”
BREAKING: Elon Musk’s Terafab has already started ordering machines from Japan for its chip factory in Texas, according to Nikkei. • One supplier was asked to deliver equipment in just a few months. • Elon is aiming for a working test chip in Austin by mid-2027 and mass production in the second half of 2028. • Terafab is aiming for 1,000,000 silicon wafers a month from 2032 onward. That would be 40 times the planned capacity of Japan’s Rapidus plant. • About 700,000 wafers a month would go toward memory chips and over 300,000 toward chips that handle computing.

What the “40 times Rapidus” figure compares
Nikkei’s “40 times” is a monthly wafer-capacity comparison, not factory floor area or investment. The arithmetic:
| Project | Monthly wafers | What it is | As of / source |
|---|---|---|---|
| Terafab (long-term plan shared with suppliers) | 1,000,000 | Informal 2032 target (~700k memory, >300k logic) | Nikkei via Asia Business Daily, 9 Nov 2026 |
| Rapidus (IIM-1, Hokkaido) | ~25,000 at full ramp | Company / METI business-plan ramp (from ~6,000 at start) | Rapidus public plan (e.g. Tom’s Hardware / Digitimes coverage of the METI plan) |
| Ratio | 40× | 1,000,000 ÷ 25,000 | Matches Nikkei’s “ラピダスの40倍” headline framing |
Neither figure is installed capacity today. Terafab’s 1 million is a reported long-term plan; Rapidus’s ~25,000 is its stated full-ramp target. Rapidus’s early mass-production rate is lower (~6,000 wafers a month), so 40× is specifically versus the ~25,000 full-ramp figure Nikkei and English summaries use.
What’s reported and what’s on the record
The orders and the Japan trip come from Nikkei’s suppliers, not from Tesla, SpaceX or Musk. The 1 million wafer figure is described as a long-term plan shared informally with equipment makers, so treat it as a target. I couldn’t find any official company statement confirming it.
The timeline does line up with what Musk has said in public. On SpaceX’s third-quarter call in October 2026, he put the goal for mass production at around the third quarter of 2028 and called it “a very aggressive schedule,” adding that it could slip to the third or fourth quarter, per Asia Business Daily’s summary of the same Nikkei reporting. If the 2028 date holds, tools ordered now for delivery in a few months would be going into the first lines more than two years before that.
The equipment side also fits what Musk said at X Takeover on 10 Oct 2026. In the full interview, looking at existing fabs, he said, “there’s not a ton of customized equipment here. Like the equipment’s all pretty much coming from the same vendors.” His plan was to “start with the conventional equipment and then we’re going to modify that equipment to improve the throughput,” and to build custom tools “where we see the choke points.” Japan is home to many of the companies that make that conventional equipment, so a buying trip there is the first step he described.
How the numbers compare
The memory split stands out. About 70% of the planned wafers would go to memory and the rest to logic, the kind of chips that run AI models. Most of the coverage of Terafab so far has been about AI processors, so a plan weighted this heavily toward memory is new information, if Nikkei’s sources have it right.
A 2032 plan can change many times before then, and the only mass-production dates Musk has given publicly are for 2028. I ran the bigger-picture math on Terafab’s scale in an earlier piece, and the chip roadmap behind it is in this one. Related: Baron on orbital data centers.
For now the hard facts are the orders. Suppliers say they’ve been asked to deliver tools within months, and if those tools ship on time, there will be something physical to check against the 2028 target.
What’s confirmed and what isn’t
- Confirmed on the record (Nikkei headline / open teaser, 9 Nov 2026): “40 times Rapidus” production-volume framing; Terafab procurement team secretly visited Japan; supplier quote naming Musk as the industry’s biggest topic.
- Reported via Nikkei (English summaries, e.g. Asia Business Daily): 1,000,000 wafers/month from 2032; ~700k memory / >300k logic; early-November supplier visits; some orders with delivery only months away; “unreasonable order” supplier quote; Musk Q3 2028 mass-production goal from the SpaceX call.
- Independent check on the 40× math: 1,000,000 ÷ Rapidus ~25,000 wafers/month full-ramp plan = 40 (Rapidus public capacity plan).
- On the record (Musk at X Takeover, 10 Oct 2026): start with conventional vendor equipment, then modify / customise at choke points.
- Not used here without a primary check: mid-2027 Austin test chip, Intel partnership, and other extras in amplifier posts.
- Not disclosed by Tesla / SpaceX / Terafab: official confirmation of the Japan orders, the 1 million wafer plan, or named suppliers.
