The Rocket Company Compute Model - URL: https://www.sotkn.com/stack/hyperscalers/what-does-spacex-do/ - Published: 2026-11-01T04:55:07.000Z - Updated: 2026-11-01T04:55:07.000Z - Description: SpaceX builds and runs AI data centers in Memphis and Southaven, trains Grok, and rents about half its compute to others. Revenue is surging, but turning on power and cooling for new GPUs is the step that binds. - Author: Sean - Tags: #layer-hyperscalers STACK · Hyperscalers · Status: Tightening · Last reviewed: 1 Nov 2026 SpaceX, best known for rockets and Starlink, now also builds and runs large AI data centers. Through its Super Intelligence segment it fills those halls with NVIDIA GPUs, trains its Grok models on them, serves its own AI products, and rents a large share of the capacity to other AI labs for a fixed monthly fee. **In short.** SpaceX now runs one of the fastest-growing AI compute businesses in the world. Its Super Intelligence segment builds GPU data centers in Memphis and Southaven, trains Grok, and rents roughly half its capacity to other AI labs. In July–September 2026 that segment earned $7.56 billion of revenue, more than half of the group total, on 1.7 GW of nameplate compute. Our read: SpaceX gets paid monthly for reserved capacity, and pays Nvidia, lenders and builders first. The stuck step is power and cooling: management is aiming for about 13 GW by the end of 2027, and says the gear to switch on new GPUs, not the GPUs themselves, sets the pace. Why an investor cares: in one year this business went from a loss-making side bet to more than half of SpaceX's revenue, and it spent $16.4 billion on compute capex in a single quarter. If you want the basics of the group it is joining, start with [who the hyperscalers are](https://www.sotkn.com/explained/who-are-the-hyperscalers/). This page is about how SpaceX's version makes money, and where it gets stuck. ## Numbers that matter | Number | What it is | Why it matters | | ----------- | ----------------------------------------------- | ------------------------------------------------------------------------- | | **$7.56bn** | Super Intelligence revenue, July–September 2026 | Up from $813m a year earlier; 52% of group revenue, our arithmetic | | **1.7 GW** | Nameplate compute at 30 September 2026 | From 0.6 GW a year earlier; 2.5–3 GW targeted by the end of 2026 | | **$16.4bn** | Super Intelligence capex in the quarter | About 3.3 times the segment's $4.95bn adjusted EBITDA, our arithmetic | | **34.5%** | Group revenue from one unnamed SI customer | The cloud business is concentrated in a few large renters | | **$40bn** | GPU finance lease led by Apollo | Rent starts only when Vera Rubin GPUs arrive, from the first half of 2027 | *Company figures are listed at the end of the page. Shares and ratios are our arithmetic from SpaceX's third-quarter release.* ## What does SpaceX actually do in AI? It owns the whole chain from the power plant to the chatbot. The AI business, which the filings call SpaceXAI, operates the Colossus data centers in Memphis, Tennessee, and is adding capacity there and in Southaven, Mississippi, where mobile gas turbines supply power for Colossus II. It buys the GPUs, the networking and much of the electrical gear itself, and in 2026 it bought Mesh Optical, a maker of optical transceivers, for $249 million in stock. On top of that hardware sit its own products. Grok is its family of AI models and apps. X, the social network, brings in advertising. Cursor, the AI coding tool, joined on 14 August 2026 in a deal valued at $60 billion of implied equity, and contributed $608 million of revenue in its first half-quarter. SpaceX also introduced an always-on agent product during the quarter. The third use is renting. Since the second quarter of 2026 SpaceX has sold reserved compute to outside AI companies. Its 10-Q describes these as stand-ready promises of continuous access to reserved capacity, paid as fixed monthly fees. That is the same product a neocloud sells, which is why the line between the two kinds of company is blurring; our guide to [neoclouds versus hyperscalers](https://www.sotkn.com/explained/neocloud-vs-hyperscaler/) sets out the difference. ## How does SpaceX make money from AI? Mostly from renting and running compute. In July–September 2026 the Super Intelligence segment had $7.56 billion of revenue. Of that, $7.02 billion came from what SpaceX calls SI solutions and infrastructure, which covers cloud services, Grok and Cursor subscriptions, API access and data licensing. Advertising on X added $538 million. The jump came from the renters. SI solutions and infrastructure revenue was $2.19 billion in the June quarter and $359 million a year earlier. Even without Cursor it grew 192% in a quarter, which SpaceX put down mainly to new cloud services agreements switching on. One SI customer, not named in the 10-Q, accounted for 34.5% of the whole group's revenue in the quarter, about $5.0 billion on our arithmetic. The only cloud customer SpaceX has named is Anthropic. In May 2026 Anthropic said it would take all of the capacity at Colossus 1, more than 300 megawatts and over 220,000 NVIDIA GPUs. SpaceX's filings put the price at $1.25 billion a month through May 2029, across Colossus and Colossus II, but either side can end it on 90 days' notice. Elon Musk later described it as a 180-day lease with mutual cancellation after that. Our [analysis of short compute contracts](https://www.sotkn.com/analysis/short-contracts-40m-mw-where-cash-sticks/) looks at who carries the risk when terms are that short. The margins have turned. The segment lost $1.72 billion at the operating line a year earlier; in the third quarter it made $431 million, after $1.2 billion of stock compensation tied to the Cursor deal. Segment adjusted EBITDA, which strips out depreciation and stock compensation, was $4.95 billion. Depreciation alone was $2.47 billion in the quarter, a reminder of how fast the hardware wears out on paper. ## How fast is it growing? ![What does SpaceX do in AI: nameplate compute of 0.6 GW in September 2025, 1.4 GW in June 2026, 1.7 GW in September 2026, a target of 2.5 to 3 GW by the end of 2026 and about 13 GW by the end of 2027](https://storage.ghost.io/c/cd/10/cd10e222-131f-4ba4-b4a9-ca4214e8c12d/content/images/2026/11/spacex-nameplate-compute.png) Nameplate compute, actual and management target. Second Order chart from SpaceX figures. The chart shows the plan. SpaceX counts nameplate compute as the GPUs installed multiplied by their all-in power, excluding cooling and other overhead, so it measures chips in place rather than power used. That figure went from 0.6 GW to 1.7 GW in a year. On the 20 October call the company said it expected nearly 2.2 GW by the end of October and 2.5 to 3 GW by the end of 2026. For 2027 the targets jump. Musk said he was highly confident of adding 10 GW of compute next year, for about 13 GW in total, and that more than 20 GW was a small but rising possibility. He also said SpaceX wants its largest training cluster, built on NVIDIA's Vera Rubin, online by the end of the second quarter. These are management's targets. The bars for end-2026 and end-2027 in the chart are plans, not results. The money is moving with it. SpaceX guided fourth-quarter capex of $35 billion to $40 billion, against $19.6 billion in the third quarter, and first-quarter 2027 revenue of $33 billion to $37 billion, against $14.6 billion in the third quarter. It also repeated a goal of $100 billion of annualised revenue by December 2026\. Its finance chief said new compute is paying back in less than a year at current prices, and that pricing was running slightly above the top of the $30 to $50 per watt range it gave a quarter earlier. Those are company claims; the filings do not break out the payback. ## Who gets paid first? - **NVIDIA and the hardware chain.** Servers and networking gear on SpaceX's books rose from $22.7 billion at the end of 2025 to $43.2 billion at 30 September, and another $23.7 billion sat in construction in progress, mostly servers and data center infrastructure not yet in service. - **Lenders and lessors.** On 24 October SpaceX committed to a finance lease of about $40 billion of GPU pods with an Apollo-managed lessor, backed by BlackRock, Goldman Sachs Asset Management and KKR-advised accounts. Rent is paid quarterly in advance at one-twentieth of each tranche plus a fixed rate. Our [Wire on the Apollo lease](https://www.sotkn.com/wire/spacex-40b-apollo-gpu-lease-2027-wire/) has the details. - **Power and site suppliers.** SpaceX bought $480 million of Tesla Megapack batteries in the nine months to September, and in a dispute over Memphis-area construction, where SpaceX is suing a contractor for more than $500 million, the other side has recorded liens of about $569 million for work it says is unpaid. - **SpaceX, last and monthly.** Renters such as Anthropic pay fixed monthly fees for reserved capacity, and Grok, Cursor and X users pay subscriptions and see ads. Cash comes in after the GPUs are bought, powered and switched on. The pattern matches the rest of the layer: the builder pays upfront for chips, halls and power, then earns it back by the month. Our guide to [finance leases versus operating leases](https://www.sotkn.com/explained/finance-lease-vs-operating-lease/) explains why the Apollo deal counts as borrowing. ## What limits it? Power, cooling and electrical gear. Musk said on the call that the constraint on deploying AI is now more in power, cooling and infrastructure than in chips, and that SpaceX is aiming for 20 GW of new power and cooling in 2027 so that the electrical side runs ahead of the GPUs it has to feed. He said he does not expect everything to go right, which is why he gave 10 GW as the confident case. The sharpest point is the gas turbine. Musk said turbine makers had told SpaceX that blades and vanes, the cast metal parts inside the hot section, arrive 12 to 18 months after the rest of the turbine. SpaceX plans to cast its own using the foundry skills it built for rocket engines, and claims that lets it bring power on 12 to 18 months faster than rivals. That claim is untested at this scale. Permits are the second limit. The 10-Q discloses a suit filed in April by the NAACP alleging that the mobile gas turbines powering Colossus II in Mississippi need Clean Air Act permits they do not have. On 19 October the court let the US government intervene but declined to dismiss the case. Our [analysis of gas turbine waits](https://www.sotkn.com/analysis/if-gas-turbines-stay-booked-into-2030-where-cash-sticks/) and our guide to [how much power an AI data center uses](https://www.sotkn.com/explained/how-much-power-does-an-ai-data-center-use/) show why on-site gas has become the fallback for halls that cannot wait for the grid. The third limit is money and timing. SpaceX ended September with $89.9 billion of cash and marketable securities, much of it from its IPO, against $38.8 billion of debt and finance leases, our sum. But it also had $37.8 billion of non-cancelable commitments, $25.6 billion of them due in 2027, mostly for AI infrastructure and outside cloud capacity, before the Apollo lease. At full size that lease adds about $2 billion of principal a quarter once all tranches are delivered, our arithmetic. Our read on the stuck step: for the next year it is switching on power and cooling fast enough for the GPUs SpaceX has already paid for or financed. Demand is not the problem on the company's account. Musk said SpaceX could rent its compute several times over. That is why we mark the status Tightening. ## Who else does this? SpaceX sits between two models on this layer. Like [Meta](https://www.sotkn.com/stack/hyperscalers/what-does-meta-do/) and Google, it builds frontier models on its own hardware. Like [Oracle](https://www.sotkn.com/stack/hyperscalers/what-does-oracle-do/) and [CoreWeave](https://www.sotkn.com/stack/neoclouds/what-does-coreweave-do/), it rents large blocks of GPUs to AI labs. Musk said the aim is to split compute roughly half and half between its own use and renters, shifting as far as 60/40 either way, and to rent on short terms close to spot prices rather than lock in long deals. That last choice is the real difference. On our read, most hyperscalers and neoclouds sell multi-year capacity so lenders can see the cash. SpaceX is betting that the value of each watt of compute rises as models improve, so short contracts reprice upward; Musk said renewals were coming in at higher dollars per watt. The cost is less certainty on revenue, which its 90-day termination terms make plain. For how the incumbents secure electricity, see [how hyperscalers buy power](https://www.sotkn.com/stack/hyperscalers/how-do-hyperscalers-buy-power/). It is also trying to reach further up the chain than anyone else on the layer. Musk said SpaceX hopes to run a first test chip at a research fab in Austin around May or June 2027 and is aiming, with large error bars by his own account, for volume chip production around the third quarter of 2028\. That is an aspiration, not a plan with disclosed spending. ## What would change this view? - **Easing:** SpaceX reports nameplate compute near 3 GW at the end of 2026 with turbines and cooling running ahead of GPU deliveries, and the Colossus II permit case is resolved. - **Tightening further:** the year-end compute target slips, the Apollo lease fails to close before year end, or a court order limits the mobile turbines in Mississippi. - **A demand shift:** a large renter uses its 90-day exit, or renewals come in at lower dollars per watt, which would test the short-contract bet. ## Practical takeaways Read SpaceX's AI business as a builder that rents out half its halls and keeps half for itself, with power as the gate. Its revenue now depends on how many gigawatts it can switch on each quarter, not on finding customers. The next checkpoints are the Apollo lease closing before the end of 2026, the year-end nameplate figure in its fourth-quarter results, and the first Vera Rubin deliveries in the first half of 2027\. Our explainer on [hyperscaler capex lines to watch](https://www.sotkn.com/explained/hyperscaler-capex-lines-to-watch/) shows which numbers to check in those reports. ## FAQ **What does SpaceX do in AI?** SpaceX builds and runs AI data centers, mainly its Colossus sites around Memphis and Southaven, fills them with NVIDIA GPUs, and uses the compute three ways: training its Grok models, serving its own products such as Grok and Cursor, and renting capacity to other AI companies under cloud services agreements. It reports all of this as its Super Intelligence segment. **How big is SpaceX's AI business?** In July–September 2026 the Super Intelligence segment had $7.56 billion of revenue, more than half of SpaceX's $14.58 billion total, and $4.95 billion of segment adjusted EBITDA. It had 1.7 GW of nameplate compute at 30 September and spent $16.4 billion of capex in the quarter. **Is SpaceX a hyperscaler?** On our reading it now behaves like one. It owns the halls, buys GPUs at hyperscale, trains frontier models and rents capacity to outside customers. It differs from Amazon, Microsoft and Google in renting mostly whole blocks of reserved capacity to a few AI labs rather than selling a broad public cloud. **Who rents compute from SpaceX?** The only cloud customer SpaceX has named in its filings is Anthropic, which agreed in May 2026 to pay $1.25 billion a month for capacity across Colossus and Colossus II. One unnamed SI customer made up 34.5% of SpaceX's third-quarter revenue. **What limits SpaceX's AI growth?** Power, cooling and electrical gear, on management's own account. SpaceX says it is confident of adding 10 GW of compute in 2027 and is planning 20 GW of power and cooling, partly by casting its own gas turbine blades and vanes, which suppliers say run 12 to 18 months behind the rest of the turbine. **Is this a recommendation to buy SpaceX?** No. This page explains how SpaceX's AI business makes money and where it can get stuck.
