SpaceX said on 12 November that it is advancing two supercompute projects, one at Starbase in Texas and one in Cochise County, Arizona, which “Together, they represent more than $74 billion in planned American investment”, according to an update on its website. The Texas facility is planned at up to $24 billion and the Arizona campus at roughly $50 billion.
By our arithmetic, $74 billion is about 1.5 times the $48,069 million SpaceX spent buying property, plant and equipment in the first nine months of 2026, according to its 10-Q, and about 3.8 quarters of capital spending at its third-quarter rate of $19,593 million.
Business Pill · Grid Cost Allocation
A short Business Engineer explainer on how grid costs are allocated. It teaches the general idea only and does not discuss these projects.
The key insight: As we read the update, SpaceX is pricing the two sites in power and water terms as much as in dollars: Starbase is to make its own electricity off the public grid, Cochise is to use dry cooling with no planned industrial groundwater use, and the combined $74 billion is about 1.5 times what SpaceX spent on property and equipment in the first nine months of 2026, by our arithmetic.
The update describes “a major new supercompute facility at Starbase in the Rio Grande Valley in Texas, and a second campus in Cochise County, Arizona”. It was relayed on X shortly after 16:00 UTC by accounts including FirstSquawk, which wrote “SPACEX PURSUING ~$50 BILLION SUPERCOMPUTE CAMPUS IN ARIZONA”.
SpaceX says the Texas facility will “train frontier intelligence systems” and help “develop and test technologies for the future of space-based computing”. The update opens by citing the “$100B Terafab advanced chip manufacturing project in Grimes County, Texas”, announced earlier.
SpaceX’s two supercompute projects as it described them on 12 November 2026 (up to $24 billion at Starbase, Texas; roughly $50 billion in Cochise County, Arizona), with its nine-month 2026 spending on property, plant and equipment from the 10-Q, the City of Starbase notice and the 6 GW+ figure the Arizona Daily Star reported citing The Arizona Republic.
Starbase: $24 Billion and Its Own Power
In Texas, SpaceX writes that it is “planning to invest up to $24 billion in this project alone”, on SpaceX-owned property near the Port of Brownsville. It says the project “has already generated more than 3,000 construction jobs” and will support more than 500 permanent jobs.
The facility “will generate its own electricity rather than drawing power from the public grid”. That matches the City of Starbase notice we covered in our piece on the Starbase tax break, which describes a “gas-fired power plant and super-compute facility” with a hearing on 9 December.
SpaceX also says it has “committed $220 million in private capital” to expand water and wastewater infrastructure for Brownsville and Cameron County, of which it has already provided $40 million. It says closing that gap through traditional financing “could have cost local water customers more than $370 million over 25 years”. By our arithmetic, $220 million is about 0.9% of the $24 billion.
Cochise County: Roughly $50 Billion
In Arizona, SpaceX says it is “pursuing a roughly $50 billion supercompute campus” expected to create approximately 5,500 construction jobs and 1,000 permanent jobs. Working with local electric cooperatives, it says the project could “potentially reduce electricity bills for cooperative members by up to 20%”.
The update says the campus “will use dry cooling, with no planned industrial groundwater use or new wells”. SpaceX does not give a power figure for the site in the update. The Arizona Daily Star reported, citing The Arizona Republic, that the campus would demand more than 6 gigawatts when completed, as our piece on the Arizona campus records. On those figures, roughly $50 billion is at most about $8.3 billion per gigawatt, by our arithmetic.
The $74 Billion Against SpaceX’s Capex
SpaceX’s 10-Q shows purchases of property, plant and equipment of $48,069 million in the nine months to 30 September 2026, against $13,846 million a year earlier. Its AI segment, which it calls SI, accounted for $39,995 million of capital expenditures in the nine months and $16,444 million of $19,593 million in the third quarter, as our piece on the Q3 capex set out.
By our arithmetic, the two projects equal about 1.5 times the nine-month spend on property and equipment and about 1.85 times the SI segment’s nine-month capex. SpaceX does not say over how many years the $74 billion would be spent.
Per permanent job, the figures SpaceX gives work out to at most about $48 million in Texas ($24 billion for more than 500 jobs) and about $50 million in Arizona ($50 billion for 1,000 jobs), by our arithmetic. Together, the two sites name about 8,500 construction jobs or more.
The Structural Read
As we read the 10-Q next to the update, the AI segment already took $39,995 million of capex in nine months, so the two sites extend a build that is under way rather than start one.
As we read the two local processes together, both sites go before local bodies on 9 December, the Starbase tax agreements and the Cochise County hearing, so the plan still depends on approvals SpaceX names in its own update.
SpaceX, update on spacex.com/updates, 12 November 2026
“We’re ready to build. And we’re committed to making sure the communities where we build share in the benefits.”
Three Implications
FOR SPACEX The update ties the $24 billion Texas figure to a stable, competitive, and supportive policy environment, and the Starbase tax agreements are still being worked out.
FOR ARIZONA COOPERATIVES SpaceX says bills for cooperative members could fall by up to 20%; the update gives no method for that figure.
FOR BROWNSVILLE WATER SpaceX says it has committed $220 million, provided $40 million so far, and that the city and its utilities board will retain full ownership of the facilities.
The framework argues: “The structural bottleneck isn’t computing, it’s electrons.”
As we read it, SpaceX’s update answers that bottleneck site by site: its own generation in Texas and cooperative power in Arizona. The framework predates the announcement and does not discuss these projects.
The project figures are SpaceX’s, from its 12 November 2026 update; capital spending is from SpaceX’s Form 10-Q for the quarter ended 30 September 2026. The 1.54x and 3.8-quarter comparisons are our arithmetic.
What Is Not Established
The update gives no start or completion dates, no compute capacity in chips or megawatts, and no customer for either site. The Texas figure appears as both “more than $24 billion” and “up to $24 billion” in the same update; the Starbase notice called its $24 billion an estimate “for initial phases of the project”.
Both projects still need local approvals: SpaceX says the Arizona campus is “seeking approval”, and the Texas tax agreements are being worked out with the City of Starbase and Cameron County. Our arithmetic compares a multi-year plan with spending already made and is not a forecast.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
SpaceX has put more than $74 billion of planned investment on two supercompute sites, up to $24 billion at Starbase with its own power and roughly $50 billion in Cochise County with dry cooling. That is about 1.5 times what it spent on property and equipment in the first nine months of 2026, by our arithmetic.
A note on sourcing. The announcement and every SpaceX claim here come from SpaceX’s own update on spacex.com/updates, read in full on 12 November 2026; capital-spending figures come from SpaceX’s Form 10-Q for the quarter ended 30 September 2026 on SEC EDGAR. The 6-gigawatt figure is the Arizona Daily Star’s, citing The Arizona Republic, and the Starbase notice is the City of Starbase’s, both as recorded in our earlier pieces. Ratios, per-job and per-gigawatt figures are our arithmetic. We did not contact SpaceX for this piece.
