SpaceX S-1: Anthropic is paying SpaceX $1.25B per month through May 2029 under their compute deal; Anthropic says it is expanding the deal to include Colossus 2
Anthropic is paying SpaceX $1.25 billion per month through May 2029 as part of the massive compute deal the companies signed earlier this month.

Context & Ripple Effects
Earlier coverage described Anthropic taking all available Colossus 1 compute capacity, with more than 300 MW expected within a month. The new disclosure puts a long-duration payment figure behind that capacity commitment and extends the relationship to Colossus 2.
The coverage also contains an important qualification: SpaceX’s filing describes monthly payments through May 2029, while Elon Musk characterized the arrangement as a 180-day lease with 90 days’ notice. That distinction affects how firmly either party is locked into the reported economics.
First-order effects
Anthropic secures a broader supply of dedicated compute across Colossus 1 and Colossus 2, while taking on reported monthly payments of $1.25 billion under the SpaceX arrangement.
SpaceX gains a major contracted revenue source tied to AI-compute capacity, though the later characterization of the deal as a short lease introduces uncertainty around its practical duration.
Second-order effects
A commitment of this scale raises the bar for rival AI developers seeking large blocks of near-term compute: they must secure comparable infrastructure or compete for remaining capacity.
Operators of large compute campuses gain evidence that anchor-customer contracts can support expansion, but customers and investors will scrutinize cancellation and renewal terms rather than headline contract duration alone.
Third-order effects
If such arrangements persist, frontier-model development will become more tightly shaped by access to power-dense, dedicated compute campuses and by a small set of infrastructure providers able to build them.
The conflicting accounts of term length point to a structural tension in AI infrastructure: providers need long-horizon commitments to finance capacity, while model developers seek flexibility as demand and hardware requirements change.
The trend: AI labs are moving from general-purpose cloud consumption toward bespoke, high-capacity infrastructure commitments, even as the contractual durability of those commitments remains contested.
We're expanding our partnership with @SpaceX, and will be scaling up on GB200 capacity in Colossus 2 throughout June. Appreciate @elonmusk and the team helping us find good homes for the Claudes.

Holy: After Anthropic secured compute capacity from Colossus 1, it is now also getting access to compute from Colossus 2. But to be honest: I somehow expected to his. Grok certainly doesn't need all that compute.
As the recently expanded partnership with @AnthropicAI demonstrates, @SpaceX is offering AI compute as a service at significant scale. We are in discussions with other companies to do the same. Over time, especially with orbital data centers, we expect to serve AI at extremely
the Anthropic rev alone is $15B for NTM 2025 revenue for the entire business was in total only $18.7B Note that Anthropic has a 90 day out. Would be a huge hit to revenue. https://x.com/...
spacex revenue was $4.69B in Q1 pre-anthropic deal. now anthropic is paying them $1.25B monthly for compute. that means anthropic likely currently makes up *nearly half* of spacex revenue.
This is about 2X of what I was expecting in terms of revenue from Anthropic to SpaceX. But they are also selling them compute from Collosus 2 so makes sense.

Anthropic and OpenAI both want to go public first, because it lets you set the narrative rather than being defined by your rival. BUT: There's also an argument that the one that pulls trigger first is doing so because it's numbers are inferior (i.e. doesn't want the known comp)
