Musk Terafab Formal Announcement (X Post)
Summary
Elon Musk's March 21, 2026 X post announcing the Terafab project — the originating primary source for the entire story. Confirmed the joint venture between Tesla and SpaceX (with xAI and Intel joining later), the ~1 TW/year compute target, and the ~80%/20% split between space-based and terrestrial deployment. Still needs a preserved screenshot or archive.org snapshot — X posts are volatile and this one is the root of the timeline.
Key Excerpts
"Formal announcement of the TERAFAB project, which will be done jointly by @SpaceX and @Tesla, tonight around 8pm CT. Livestream on 𝕏. The goal is to produce over a TERAWATT of compute per year (logic, memory & packaging) with ~80% for space and ~20% for the ground."
Why it matters: Musk's own framing of the scale and split — the 80/20 space-to-ground ratio is the single most quotable structural claim of the entire project, and every subsequent piece of coverage has echoed or questioned it.
