SpaceX adds USD1.11 billion a month of hosted compute: what it means for three listed holdings

SpaceX no longer wants to be understood only as a rocket and satellite company. Its chief financial officer has disclosed a new hosted-compute contract worth about USD1.11 billion a month from 1 December. Annualised, that is USD13.32 billion. Yet the arrangement comes with short commitment periods: the figure is neither guaranteed annual revenue nor value that automatically accrues to the three listed holdings exposed to SpaceX.

The new fact: SpaceX is also becoming a compute host

At a Goldman Sachs conference published on 10 September, SpaceX chief financial officer Bret Johnsen said the company had signed a hosted-compute agreement worth USD1.11 billion a month, starting on 1 December.

The service provides the computing power, electricity, cooling, networking and operations needed for intensive workloads. The customer has not been identified. SpaceX has not said whether the capacity will train artificial-intelligence models, run them or process other workloads.

The USD13.32 billion annual figure is an Opulion calculation, not company guidance. It simply multiplies the monthly rate by twelve. In the same discussion, management described compute arrangements with roughly 90 days of commitment and a further 90-day exit mechanism. An annualised run-rate is therefore not the same as a firm multi-year order book.

Why this changes the way investors should read SpaceX

SpaceX already combines two economic models. Launch and Starlink share a technology base but sell different products. Launch charges for access to space. Starlink sells recurring connectivity to consumers, companies and governments.

Hosted compute adds a third layer. SpaceX deploys capital into buildings, chips, power systems and cooling, then sells computing capacity. Management is also targeting 5 to 10 gigawatts of terrestrial capacity next year, compared with a little over 2 gigawatts expected by the end of the current year, according to the conference transcript.

The industrial logic is credible: SpaceX operates complex energy and communications infrastructure and ultimately wants to move some computation into orbit. Yet the terrestrial capacity being announced first competes with specialist data-centre and cloud providers. The new business is not a free extension of Starlink.

Three holdings, three different transmission mechanisms

Scottish Mortgage: the most visible exposure

Scottish Mortgage reported on 11 June that SpaceX represented 22% of its portfolio, worth GBP3.78 billion. The trust had invested GBP151.1 million. The published value was therefore about 25 times invested capital, before any tax or future dilution.

The position is large enough for changes in SpaceX's fair value to move the trust's net asset value directly. Hosted compute may broaden the addressable market, but it also adds capital requirements and complexity. For Scottish Mortgage shareholders, the opportunity and the concentration risk rise together.

US Growth: an even more concentrated weight

Baillie Gifford US Growth valued SpaceX at GBP163.6 million, or 17% of assets, on the same date. It had invested GBP5.9 million, making the published value about 28 times cost.

The sterling amount is smaller than Scottish Mortgage's, but the relative weight remains exceptional. A fresh SpaceX valuation can therefore transmit strongly into this smaller trust's net asset value per share. Conversely, a multiple reset or dilutive financing could matter more than the absolute pound figure suggests.

Sofina: exposure is confirmed, but the weight is hidden

Sofina ranks SpaceX as its largest indirect exposure through private-equity funds. The Belgian holding company does not disclose the individual value. It says only that its ten largest indirect holdings together represent about 10% of the funds' look-through portfolio.

Investors therefore know SpaceX matters but cannot calculate its exact effect on Sofina's net asset value. That transparency difference is central: the same operating development is directly quantifiable in the two UK trusts and only directional at Sofina.

USD13 billion does not create a valuation by itself

A company valuation depends on more than revenue. Investors need margins, contract duration, required investment, customer risk and financing costs. Several pieces are missing here:

- the customer's identity and credit quality; - the contract's genuinely firm duration; - the capital expenditure required; - the margin after power, chips, cooling and operations; - the capacity already built versus the capacity still to be funded.

The agreement represents about 13.3% of management's USD100 billion year-end annualised-revenue ambition. That comparison gives scale. It does not prove SpaceX will reach the target or that compute will earn the same return as Starlink or launch.

Opulion's earlier article on SpaceX, OpenAI and Anthropic inside Sofina's indirect portfolio explained the visibility problem. The new point is operational: the value engine itself is broadening into a business whose economics remain thinly documented.

What shareholders should watch

Opulion view. The contract makes SpaceX harder to classify, but potentially more powerful: it is trying to turn its capabilities in energy, networks and infrastructure into a computing platform. For shareholders in the three holdings, the useful question is not “is SpaceX worth more today?”. It is “how much incremental value remains after the required capital, potential dilution and the customer's short commitment?”.
