**SpaceX** is selling **orbital compute** as a rentable service years before the hardware that delivers it leaves the ground. The company holds multi-year capacity agreements with **Anthropic** valued near $1.25 billion a month and with **Google** at roughly $920 million a month, alongside a separate AI hosting contract worth about $1.1 billion monthly that begins in December 2026.

Those commitments exceed $3 billion in monthly contracted demand. The first satellites meant to serve them are not scheduled to launch until the fourth quarter of 2027, with meaningful operational scale arriving in 2028\. The hard part is delivery against contracts already signed, on a schedule SpaceX alone controls.

SpaceX CFO Bret Johnsen has set a $100 billion annualized revenue run rate as the target for the end of 2026\. Almost none of that will come from orbit.

## Signed Contracts, Unbuilt Capacity

The agreement economics are unusual for infrastructure of any kind. Buyers are committing years ahead of delivery, on a service with no operating history and a launch cadence that has not been demonstrated at the required volume.

| Agreement                                   | Monthly value | Annualized | Delivery window      |
| ------------------------------------------- | ------------- | ---------- | -------------------- |
| Anthropic                                   | \~$1.25B      | \~$15.0B   | Multi-year           |
| Google                                      | \~$920M       | \~$11.0B   | Multi-year           |
| New hosting deal (counterparty undisclosed) | \~$1.1B       | \~$13.2B   | Begins December 2026 |

SpaceX President Gwynne Shotwell has confirmed that the Anthropic and Google arrangements cover rented orbital capacity rather than terrestrial hosting. That distinction matters, because the orbital product does not yet exist as a deployed fleet.

What exists is a design. SpaceX has said the platform will reuse the same V3 satellite bus that carries Starlink broadband, fitted with modified payloads and larger solar arrays to handle the power draw of accelerated computing. The compute would come from a space-optimized version of Nvidia's Vera Rubin NVL72 system.

Note the sequencing in the third row of that table. A contract that starts paying in December 2026 cannot be served by satellites launching in late 2027, which means near-term hosting revenue is being met from ground infrastructure. SpaceX is running two businesses under one AI label, and only one of them is airborne.

The buyers' motivation is easier to read than the seller's. Anthropic and Google are securing compute capacity outside the interconnection queues that govern most new AI capacity, and they are paying for the option years ahead of delivery. That is a defensible hedge for two companies whose training and inference demand is growing faster than any single power market can absorb.

These are capacity agreements, which means the buyers have committed to paying for something produced on a schedule SpaceX controls. Delivery risk sits with the seller, and that is why the leadership changes below matter more than a routine reshuffle would.

## Why Orbital Compute Changes the Math

The pitch rests on constraints that terrestrial operators cannot engineer away. Ground-based AI campuses compete for grid interconnection, cooling water and land near population centers, and permitting timelines in those markets routinely run longer than the hardware procurement cycle. SpaceX has framed orbital hosting as a route around all three.

Solar arrays do the work that a utility interconnection agreement does on the ground. In orbit there is no queue, no water permit and no neighboring municipality to negotiate with, which is exactly the bottleneck set SpaceX has identified as the reason terrestrial buildout keeps slipping.

Hardware mass is where the orbital argument gets concrete. SpaceX describes its space-grade racks as lighter, denser and cheaper to field than conventional terrestrial server racks. Every kilogram saved is launch mass that does not have to be paid for, and every rack that skips a concrete slab and a chiller plant skips the capital cost of both. That edge holds only if launch cost per kilogram stays where SpaceX needs it, which ties the orbital compute margin directly to Starship cadence.

The program now has a name and a regulatory footprint. StarMind was formally designated in June, following SpaceX's February announcement of its xAI acquisition, and the company has filed an FCC application covering the project. Where Starlink satellites relay internet traffic between ground stations, StarMind satellites are designed to execute AI processing in orbit.

## Ground Capacity Is Still Carrying the Business

The revenue SpaceX is booking today comes from terrestrial infrastructure. Ground-based AI compute capacity is projected to reach 2 gigawatts by late 2026 and to expand into a 5 to 10 gigawatt range during 2027\. Google's hardware allocation within that footprint is roughly 110,000 Nvidia GPUs.

| Milestone                           | Timing                                    |
| ----------------------------------- | ----------------------------------------- |
| Ground AI compute capacity          | 2 GW by late 2026; 5 to 10 GW during 2027 |
| New hosting contract begins paying  | December 2026                             |
| First orbital compute satellites    | Fourth quarter of 2027                    |
| Significant orbital operating scale | 2028                                      |
| Projected orbital compute capacity  | Up to 75 GW by 2031                       |

Read that schedule as one line and the shape of the business becomes clear. Ground capacity compounds through 2026 and 2027\. Orbital capacity starts with a first launch in late 2027 and reaches meaningful scale the following year. Every dollar of the $100 billion run rate that arrives before then is terrestrial.

Launch is the other half of the machine. Starship's 14th flight is expected to be the vehicle's first revenue-generating mission, carrying V3 Starlink satellites. A reusable heavy-lift vehicle flying on commercial cadence is the precondition for putting data centers in orbit at any scale, so Starship's schedule and the orbital compute schedule are effectively the same schedule. A slip in one shows up in the other.

The capital intensity cuts both ways. Building two gigawatts of ground capacity by late 2026 is a heavy lift for a company whose core business is launch, and much of it is being funded against contracts that have not started paying. My read is that the $100 billion run rate is a statement about the ground business wearing an orbital story.

## The Execution Risk Is Real

SpaceX replaced several AI data center leaders in early September 2026, bringing in rocket and Starlink executives after reliability failures at its Tennessee and Mississippi sites. That reshuffle landed while a September 30 milestone tied to Google's GPU allocation was approaching.

The September 30 date is a useful test case. Deadlines attached to GPU allocations are contractual rather than aspirational, and they arrive on a fixed calendar regardless of how the orbital program is progressing. Meeting them from ground sites is the near-term proof that SpaceX can operate compute infrastructure at all.

Moving launch and satellite veterans into a data center organization is a revealing choice. It signals that SpaceX treats the hard part as industrial execution under schedule pressure, the muscle its launch and constellation teams have built, rather than facility operations it has been learning on the job.

The strongest counter-argument to the bullish case is temporal rather than technical. Jeff Bezos has taken a more cautious view of when orbital data centers become viable while agreeing that the destination is real. Published projections put potential orbital compute capacity at as much as 75 gigawatts by 2031, a figure far beyond the first satellites now on the manifest. If that number is even directionally right, the capacity contracted today will be delivered by hardware generations that do not yet exist.

Concentration is the second risk. Three counterparties account for the overwhelming majority of booked compute revenue, and two of them are named. A single renegotiation, or one missed delivery milestone, moves the run-rate arithmetic materially.

A second scenario deserves attention. If terrestrial permitting and power constraints ease faster than expected, orbital compute loses much of its structural edge, and SpaceX would be left selling a premium product into a market that no longer needs it. That is not today's trajectory, but it is the scenario that would quietly dismantle the thesis.

## Why this matters

SpaceX has turned rockets and a broadband constellation into a landlord business, and the demand side is paying before the buildings exist. What I would watch next is the launch manifest rather than the contract value: the case holds if the first orbital compute satellites fly on schedule in 2027, and it breaks if the revenue stays on the ground while the hardware slips. The gap between the 2026 contracts and the 2028 fleet is where this trade is won or lost.
