In a dramatic development that bodes well for its coffers, but not so for the competitiveness of its Grok AI model, SpaceX has just inked a $6.3 billion compute deal to start renting out Colossus 2 GPUs, raising question marks over its strategy to compete with the likes of OpenAI and Anthropic.
SpaceX will collect $150 million per month from July onwards by renting out NVIDIA GB300 GPUs at its Colossus 2 data center to Reflection
As of May 2026, SpaceX's Colossus 1 data center supported over 220,000 NVIDIA GPUs, divided between H100, H200, and around 30,000 units of the GB200 AI accelerators.
Meanwhile, the Colossus 2 data center currently boasts of over 550,000 GPUs, divided between GB200 and GB300 accelerators.
As we noted in a dedicated post recently, in the runup to its IPO, SpaceX locked a Cloud Service Agreement with Google, furnishing it with a compute capacity equivalent to "110,000 NVIDIA GPUs, CPUs, memory, and other related components," all for a consideration of $920 million per month.
Also, the parent company of Starlink and xAI recently inked a similar agreement with Anthropic, providing access to "220,000 NVIDIA GPUs (including H100s, H200s, GB200s, and others)," all for a consideration of $1.25 billion per month or $15 billion per year.
While the Anthropic deal is locked to SpaceX's Colossus 1 data center, where a mish-mash of GPUs renders the data center less attractive for training future iterations of Grok AI, and where xAI consumes just 11 percent of the total available FLOPs, the Google deal is primarily tied to the Colossus 2 data center.
This brings us to the core of today's topic. SpaceX has just signed another $6.3 billion compute deal for the Colossus 2 data center, this time with Pentagon-linked Reflection. Under the terms of the deal, SpaceX will furnish Reflection with access to its stash of GB300 GPUs for a consideration of $150 million per month starting in July 2026 and running through June 2029.
The question then arises: why is SpaceX lending out its compute capacity if Grok AI needs these computing resources to remain competitive? Is SpaceX slowly abandoning its own AI model, deeming it a lost cause, especially if such models are destined to become a commodity amid an onslaught of open-sourced models from China?
Of course, following a historic IPO and a gigantic bond deal, SpaceX is flushed with cash right now, to the tune of over $100 billion. What's more, SpaceX's $60 billion acquisition of Cursor is structured as an all-stock deal, which won't affect its cash-based liquidity position.
Against this backdrop, SpaceX's aggressive monetization of its compute resources raises more questions than it answers, casting a pall over the aggressive expansion currently being undertaken by OpenAI and Anthropic.
