SpaceX's WORLDCHANGING AI Complex in Texas. Literally $ Trillions

SpaceX is rapidly developing AI data-center capacity, with its 444-acre Starbase City site potentially hosting 10–20 mini-hard facilities and Tennessee projects already progressing quickly. Construction milestones include vapor barrier, concrete, steel framing, roof work, and arriving turbines, while the site’s gas infrastructure may support multiple facilities but remains a key constraint. The company’s roughly five-month Tennessee build pace is far faster than typical data-center timelines, and cited economics suggest a roughly six-month payback with substantial revenue potential. Strong demand, including sold-out hyperscaler capacity, supports SpaceX’s ability to self-fund and sell completed capacity at premium prices. The main risks are commissioning timing and pipeline capacity, though management expects build rates to ramp toward 14 GW at the site and a possible 20–30 GW bull case by late 2028.

• ▶ 0:17 Construction is moving at “mini hard speed,” with vapor barrier added September 23, concrete poured September 24, and steel framing added September 28.
• ▶ 1:47 The 444-acre/19 million sq ft site was annexed into SpaceX Starbase City and is described as a possible home for 10–20 mini hard AI data centers.
• ▶ 2:05 By mid-October, the roof is going on for about one-third of a building and turbines have arrived, while the site’s gas pipeline and roughly 500 MW of portable turbines may support multiple facilities.
• ▶ 4:49 The 444-acre site could support roughly 20 mini-hard sites, each needing about 20 acres including exterior power and cooling.
• ▶ 5:45 Pipeline capacity is a major constraint: a 24-inch line could fuel about 3 GW, while 20 mini-hards would need about 9 GW (or 14 GW at Reuben density), requiring additional gas diversion.
• ▶ 6:30 Tennessee construction is progressing quickly, with Memphis mini-hards completed in about five months, the macro hard already turned on, another site expected in December, and Texas sites possibly starting in January–March.
• ▶ 7:19 The Memphis site involves a building acquired in September; the “mini hart” is 220,000 chips, not GB300 or Reuben chips, while Jensen says over 1 million Reuben chips are going to SpaceX in 2027.
• ▶ 7:41 SpaceX’s roughly five-month Tennessee construction pace is far faster than typical data-center builds, which range from about 12 months containerized to about 22 months stick-built.
• ▶ 8:40 The estimated payback is about six months, with a 400 MW mini hard worth about $13 billion and the 220,000-chip deal bringing about $26.7 billion in revenue, much faster than CoreWeave’s roughly 2.5-year target.
• ▶ 9:27 Competitors depend on pre-sold five-year contracts and SPV financing, while SpaceX can self-fund construction and sell completed capacity at top dollar without resale lock-in.
• ▶ 10:49 Projects are being built quickly, with Tennessee expected done by November and Texas underway, pointing to completion/rental around March 2027.
• ▶ 11:36 Demand far exceeds supply—Amazon is sold out past 2028 with a tens-of-gigawatts backlog—so SpaceX can absorb capacity, with cited revenue potential around $200B and models ranging from ~$22B/year to $26.7B per mini heart.
• ▶ 13:12 The October 20 Q3 SpaceX earnings call is expected to reveal Q3 financials and likely provide Q4/Q1 revenue and execution details because the Q4 impact is described as material.
• ▶ 14:03 The main risk is commissioning timing, including hooking up turbines and 24-inch gas lines; SpaceX controls the Starbase City site, and the critical port pipeline started construction October 1 with a rough March 2027 turn-on estimate.
• ▶ 15:01 Build pace is expected to ramp from one completion per month in Q4 2026 to two per month in 2027, with 14 GW possible at this site and a bull-case path toward 20–30 GW by end of 2028, while space data centers scale by 2028 with next-generation chips.
