Key Takeaways:
SpaceX added water access as a risk factor in its IPO filing Monday, warning that scarcity could limit data center cooling capacity and delay expansion of its AI infrastructure as the company targets a valuation of at least $1.8 trillion.
"Water availability has become a critical consideration in data center site selection, development and operations," SpaceX wrote in the amended filing, which now includes Elon Musk's AI venture xAI alongside the space exploration business.
The company said data center buildouts are constrained by "availability of power and water at economically feasible prices." SpaceX also disclosed it will reserve up to 5% of Class A shares for employees and friends of executives, while more than 60% of pre-IPO shares — including Musk's stake — face a 366-day lock-up. The directed-share program gives some insiders and connected participants more flexibility to sell immediately, contrasting with the restricted majority.
The water warning introduces a novel environmental risk for one of the most anticipated listings in years. The disclosure comes amid a broader debate about data center water consumption and its contribution to localized droughts worsened by climate change. SpaceX said drought conditions, competition for local water resources and regulatory restrictions could increase costs or require alternative cooling techniques that may be more costly or less available.
The amended filing also revealed SpaceX's agreement to provide Anthropic PBC with AI computing capacity using about 325,000 Nvidia chips. The deal costs Anthropic $1.25 billion per month and runs through May 2029, though either party can terminate after the initial three-month period with 90 days' notice. SpaceX flagged that some compute customers may rely on external capital to meet their obligations.
SpaceX's orbital data center ambitions are taking shape alongside its Starlink satellite network. The company has progressed from 10 megawatts across 3,000 first-generation Starlink satellites to 100 megawatts with 7,000 second-generation units, with the upcoming third generation expected to generate 1,000 megawatts. Musk said this trend of "10xing space solar every few years" will continue for many years.
The company completed 165 missions in 2025, far below the 10,000 annual Starship launches Musk estimates would be needed to deliver 300 to 500 gigawatts of solar-powered AI satellites to orbit. Starship has yet to achieve a fully reusable flight, raising questions about the timeline for orbital data centers that could bypass terrestrial water constraints entirely.
