SpaceX IPO Filing Reveals $15 Billion Annual Compute Deal With Anthropic

SpaceX's IPO filing revealed a major compute partnership with AI company Anthropic. The deal involves Anthropic paying SpaceX $1.25 billion per month, totaling $15 billion annually, for access to its data centers through May 2029.
SpaceX IPO Filing Reveals $15 Billion Annual Compute Deal With Anthropic

SpaceX IPO Filing Reveals $15 Billion Annual Compute Deal With Anthropic SpaceX’s long-awaited IPO filing has unexpectedly turned the company into one of the most powerful players in AI infrastructure, revealing a multibillion‑dollar compute pact with Anthropic that could reshape both firms’ futures.

Early May: Partnership quietly begins

Earlier this month, Anthropic and SpaceX announced a new compute partnership giving the AI lab access to SpaceX’s Colossus data centers in Tennessee, initially framed as a way to supply more compute for Anthropic’s “booming AI business.” At the time, neither side disclosed the price tag.

May 20–21: IPO filing exposes the scale

Details emerged with SpaceX’s S‑1 IPO filing, revealing that Anthropic has agreed to pay $1.25 billion per month through May 2029 for access to Colossus I and Colossus II — about $15 billion a year, nearly doubling SpaceX’s roughly $18–19 billion in 2025 revenue. An Anthropic spokesperson confirmed the tally, which could exceed $40 billion over the life of the contract if fully executed.

The agreement includes a 90‑day termination clause for either company, a hedge against the “fast-moving nature of the AI industry” and the risk that future hardware or competition could rapidly change economics.

Anthropic’s bet: Pay up to escape compute bottlenecks

Anthropic’s revenue is “taking off,” with the company reportedly on track to more than double quarterly revenue to $10.9 billion and post its first operating profit, after years of heavy AI spending. But it has been “hampered by a lack of compute power,” making access to SpaceX’s GPU-rich facilities strategically vital.

SpaceX’s pivot: From rockets to AI utility

The IPO filing shows SpaceX has poured tens of billions into AI infrastructure, with its AI division losing $6.3 billion on $3.2 billion in 2025 revenue as it raced to build capacity. The Anthropic deal lets SpaceX “monetize unused compute capacity” while retaining the option to reallocate resources to its own models, including those from its merged xAI unit.

CEO Elon Musk publicly boosted morale amid the pivot, writing, “The SpaceX team is incredible!” on X after the IPO filing drew attention to the firm’s expanding AI ambitions.

A two‑hour news storm crystallizes the new AI order

The disclosure landed during what one analysis dubbed “two hours that changed AI,” a rapid-fire news cycle that also highlighted OpenAI’s research advances and Nvidia’s “parabolic” chip demand, underscoring an AI economy increasingly defined by who controls scarce compute.
