PendingOrbital satellites become lowest-cost AI compute
“Satellites with localized AI compute... will be the lowest cost way to generate AI bitstreams in <3 years.”
“We either build the Terafab, or we don't have the chips, and we need the chips, so we build the Terafab.”

The fine print
Deadline keyed to the AI5 volume-production-in-2027 target (overlaps existing entry #86). The terawatt/year goal has no stated date. SpaceX acquired xAI Feb 2, 2026 — relevant corporate context.

The promise: “We either build the Terafab, or we don't have the chips, and we need the chips, so we build the Terafab.” · Elon Musk on X, Mar 21 2026 — official TERAFAB announcement (a terawatt of compute/year, ~80% space / 20% ground) ↗
Today · Jul 16, 2026
Status: Pending · 533 days left. Still waiting.
At a March 21, 2026 event at Austin's Seaholm Power Plant, Musk unveiled Terafab, a Tesla/SpaceX (later joined by Intel) chip-fab venture he says is needed because existing fabs cover only about 2% of his companies' projected chip demand. Stated targets: AI5 small-batch production in late 2026, volume production in 2027, scaling toward one terawatt of AI compute output per year — against analyst estimates that a full build-out costs trillions.
