SpaceX Unveils More Than $74 Billion AI Supercomputing Campus Plan in Texas and Arizona; Both Sites Face December 9 Votes

• Dispatched: Nov 13, 2026 · 04:38 ET (09:38 UTC)

One-sentence summary: SpaceX announced on 2026-11-12 that it plans to invest more than $74 billion in two AI supercomputing campuses — more than $24 billion at its Starbase site in Texas and about $50 billion in Cochise County, Arizona (up to 6 GW) — and said its AI segment generated more than half of third-quarter revenue; both sites face local votes on 2026-12-09.

Verification status: ✓ Company statement reported by Reuters and The Wall Street Journal. Both campuses still require final local approval, and the investment figures are planned values, not contracted capacity or revenue.

Core Facts & Consensus Delta:

• Reuters reported the company statement on 2026-11-12 at 10:15 ET / 15:15 UTC; The Wall Street Journal also reported the $74 billion figure the same day.
• Starbase, Texas: more than $24 billion; the campus would generate its own electricity from a gas-fired plant on 444 acres rather than drawing from the Texas grid; it has already created more than 3,000 construction jobs and would support more than 500 permanent jobs once operating; SpaceX has committed $220 million to Brownsville-area water and wastewater infrastructure, including $40 million already provided.
• Cochise County, Arizona: about $50 billion; up to 6 GW in four phases of about 1.5 GW each, across nine single-story compute buildings of about 493,000 square feet each; about 5,500 construction jobs at peak and about 1,000 permanent jobs; dry cooling with no planned industrial groundwater use; power supplied through the Sulphur Springs Valley Electric Cooperative and the Arizona Electric Power Cooperative.
• Approvals: the Arizona campus needs a county special-use permit; a petition with about 2,400 signatures asks officials to deny it; the Cochise County Planning and Zoning Commission holds a hearing on application SU26-22 on 2026-12-09 at 16:00 ET / 21:00 UTC (14:00 local time); the Starbase City Commission votes the same day on a property-tax abatement.
• Context: SpaceX went public in June 2026 (NASDAQ: SPCX), and Reuters said its AI segment generated more than half of third-quarter revenue.
• SpaceX has not disclosed accelerator suppliers, network architecture or commissioning schedules for either campus.

Supply-Chain & Market Read-Through:

• Scale: a more than $74 billion plan and a 6 GW Arizona campus would rank among the largest single AI data-center builds announced to date. Self-generated gas power in Texas sidesteps grid queues, while dry cooling in Arizona addresses water constraints — the two tightest bottlenecks in US AI infrastructure today.
• Supply chain: construction at this scale would pull demand for GPUs and HBM, power equipment, liquid cooling and optical modules, but with no suppliers named and no phased timeline disclosed, no vendor or dollar figure can be tied to the plan; the 2026-12-09 local votes are the first gating test for whether either project proceeds on schedule.
• Related development: Bloomberg reported the same day that SpaceX and Tesla are advancing merger talks; if a combination were agreed, this compute buildout and Tesla's AI and robotics compute needs would sit under one capital plan. Neither matter has a final decision.
• Background: the Starbase figure of about $24 billion had already appeared in a 2026-11-10 city notice; 2026-11-12 is the first formal company statement and the first time the $74 billion combined figure and the full Arizona scale were given.

Next Catalysts & Watchpoints:

• 2026-12-09 at 16:00 ET / 21:00 UTC: Cochise County Planning and Zoning Commission hearing (SU26-22); Starbase City Commission property-tax abatement vote the same day.
• Clearance of the Arizona power arrangement by the state regulator.
• Any disclosure of accelerator suppliers, first-phase commissioning dates or phased capital spending.
