# SpaceX Leases $6.3 Billion of Nvidia Compute to an Open-Weight Lab, Turning Colossus Into a Merchant Cloud

The deal makes Reflection AI the latest tenant of Elon Musk's Memphis data center and shows that frontier compute, not capital, is the scarce asset labs now compete for.

SpaceX has agreed to lease Nvidia GB300 capacity inside its Colossus 2 data center near Memphis to Reflection AI, an open-weight model startup, for about [$150 million a month beginning in July, with payments reaching roughly $6.3 billion if the contract runs through 2029](https://www.cnbc.com/2026/06/22/spacex-ai-colossus-data-center-reflection.html). Either side can exit with 90 days' notice after the first three months.

The arrangement creates a circular flow of money. Nvidia [invested $800 million in Reflection](https://techcrunch.com/2026/06/22/spacex-inks-compute-deal-with-reflection-ai-an-open-source-ai-lab/), and Reflection is now paying to use Nvidia accelerators that SpaceX bought. Reflection gets the reasoning-class GB300 graphics processing units (GPUs) it needs to train models without building its own facility, SpaceX earns money from idle capacity, and Nvidia profits from its chips a second time. The deal follows earlier Colossus tenancy agreements with Anthropic, Google and Cursor, [confirming SpaceX's move into commercial compute leasing](https://t.me/aipost/7312).

The economics are straightforward. A monthly rent of $150 million implies an annual rate near $1.8 billion for a single tenant, a figure that only works if Reflection can turn that compute into models that earn back the cost. For an open-weight lab that gives its weights away, revenue must come from services, enterprise support and inference rather than licensed access. That is the assumption now being financed at a scale of several billion dollars.

What is verified is the structure of the deal and the dollar figures, which multiple outlets report consistently. What remains a claim is the strategic logic, namely whether leased capacity at this price is a step toward durable demand or a commitment that will look expensive if model revenue lags.

## What this means

Compute has become the limiting input in frontier AI, and the companies that own power, land and GPUs can now rent them at profit margins that rival the labs' own businesses. When a launch company and a chipmaker capture the cash flows around an open-weight lab, it indicates that capital is abundant and physical compute is the constraint. It also concentrates the risk in AI infrastructure. If demand for models disappoints, these long-dated leases are the first place that risk will be repriced.

## What to watch

- Whether Reflection releases open-weight models whose download and inference demand justify a roughly $1.8 billion annual compute bill. That is the test of whether the lease was a sound investment or an overcommitment.
- How many more outside tenants SpaceX signs for Colossus, which would confirm that a company built to host its own systems is becoming a commercial compute vendor competing with established cloud providers.
