Terafab: Musk's chip gigafab (compute for robots + space data centers)

Where it stands: Tesla and SpaceX are planning a huge chip campus in Grimes County, Texas, to supply chips for robots and space data centers, with Intel's 14A process named. Permits, tax incentives and foundations are moving, but there is still no groundbreaking date, no tool orders and no final Intel license. Musk has now floated, in talk only, eventually making chips on the Moon. Watch for county construction permits and lithography tool orders.

Latest

• 2026-10-25 (~12:27 AM ET relay — x.com/elonmusk): Fireside Alpha: the lunar-manufacturing layer spoken aloud — lunar soil "20% silicon or something like that": mine silicon, refine it, "create the solar cells and the radiators on the moon," radiators from lunar aluminum; chips "pretty light" to send from Earth, "but maybe at some point you make them on the moon, too." Scaling rationale: 500–1,000 terawatts a year "cannot be launched from Earth" — "a sort of a video game situation where it's difficult but not impossible to get to the next level." The same relay: NASA Artemis launch lead Jeremy Parsons calls SpaceX's between-flight Starship rebuild pace "unthinkable" in standard industry history. Fireside talk only — no plan, procurement document, or hardware artifact in the reporting. Watch: the lunar-cell pitch reaching any SpaceX program or procurement document, and corroboration of the Parsons attestation.
• 2026-10-07 (X layer, reaffirm): Intel CEO Lip-Bu Tan in Tokyo — Intel "will continue working with Elon Musk on Terafab," Intel's role in the project reaffirmed (DogeDesigner RT, X-grade single source). No tool orders, no site dates, no definitive Intel 14A license; the thread's "no announcement has added time" asymmetry continues — this entry repeats the partnership it describes.
• 2026-09-08 movement since Aug 6 = permitting and foundations only. JETI active; county agreements executed and published; Austin ATCF foundations progressing + contractor fit-out permits (Jul 27); no Grimes groundbreaking date, no first-wafer date, no lithography tool orders confirmed, no IP split. Analyst estimates: Morgan Stanley — first output no earlier than mid-2028; own-process chips 2030s. Jon Peddie: AI5 small-batch via research fab late 2026/early 2027, first Grimes chips (AI6 + D3) late 2027, volume 2028; floor split ~25% edge / 75% space; Tesla hired ex-Intel vet Gary Jiang to run 14A licensing. The asymmetry is the story: every announcement has added scale and place, none has added time. Credibility anchors: NYT — fewer than 1 in 5 of 600+ Musk predictions delivered on time; SpaceX Q2: $7.8B sales, $541M net loss; ASML CFO (Jul 15) says 2027-28 capacity plans account for Terafab demand — the one supplier-side validation. Local: ~900- signature residents' petition; on-site gas power (Memphis xAI precedent for unpermitted turbines); water from Gibbons Creek Reservoir, not groundwater. The "50×" framing is fan-amplification, not company news. Still no tool orders, no site dates, no definitive Intel 14A license; the thread's "no announcement has added time" asymmetry holds.

Background

• The thread: Tesla+SpaceX (xAI merged in Feb, "SpaceXAI") building a vertically integrated chip campus — logic + memory + packaging + testing under one roof — targeting 1 TW of compute per year, vs ~0.5 TW total US generation (Musk's own comparison). Two chip types: edge-inference for Optimus/Cybercab (AI5/AI6) and rad-hard space chips (D3) for space data centers. Intel 14A named as the process; Intel's first major external 14A commitment.
• Timeline of record: Mar 21 announced (Austin, "$20–25B headline", no date); Apr 7 Intel joins; Apr Tesla breaks ground on $3B Austin research fab (ATCF, few thousand wafer starts/mo); May 6 filings: phase 1 $55B, to $119B total; May 27 SpaceX S-1: Terafab a "general framework," no binding commitments, no finalized IP split, neither party obligated; Jun 3 Grimes County PILOT (100% abatement 2027–2036, $10M + $20M/yr × 35y = $710M; effective abatement ~78% per SpaceX counsel); Jun 12 SPCX lists on Nasdaq; Jul 14 four JETI phase agreements approved 5–2 (~$1.66B school incentives); Aug 6 site confirmed — Grimes County (Gibbons Creek Reservoir, ex-coal-plant brownfield, ~6,000 acres), $16.8B phase 1,

  100M sq ft (would be world's largest building; ~15 Pentagons), 3,000 permanent jobs, Abbott adds $30M Texas Enterprise Fund grant; SPCX +15.8% on the day.

• Watch for: Grimes County construction permits (county records move before press releases), ATCF cleanroom shell, ASML/litho tool orders, a definitive Intel 14A license replacing the framework, phase 2 activation, Brazos Valley fab-engineer hiring (18–24 mo pre-production).
