SpaceX IPO Filing Highlights Water Supply Concerns as a Growing Business Risk

SpaceX has updated its IPO filing with new disclosures highlighting a growing concern for investors: access to water.

In an amended filing submitted on Monday, the company — which now incorporates Elon Musk’s AI venture, xAI — stated that securing water supplies has become as essential as obtaining electricity, advanced processors, and other resources needed to support its expanding AI infrastructure. Water is particularly important for cooling the large-scale data centres that power artificial intelligence operations.

The revised filing arrives as scrutiny continues to grow over the amount of water consumed by data centres and whether those demands are worsening local water shortages already intensified by climate change.

In the “risk factors” section of the updated IPO document, SpaceX expanded its discussion of the challenges of scaling AI-related infrastructure.

Earlier versions of the filing emphasised that the company’s data centre growth was largely limited by access to power at economically viable rates, as well as long construction timelines and shortages of key materials. The amended version introduces several references to water availability. SpaceX now notes that the development of data centres can be limited by the availability of both power and water at economically viable prices.

The company further explains that large-scale data centre facilities may require substantial amounts of water for cooling. According to the filing, access to water has become a major factor in selecting, developing, and operating data centre locations.

SpaceX also warns that challenges such as drought, limited water supplies, competition for local resources, and government restrictions on water usage could affect its ability to secure enough water for cooling operations. The company says these issues could reduce cooling capacity, increase operating expenses, slow or prevent future data centre expansion, or force the adoption of alternative cooling methods that may be more expensive or less readily available.

At this stage, it remains unclear why SpaceX chose to add the new water-related disclosures or why the topic was not included in the initial filing. The company is currently in the pre-IPO phase, during which the Securities and Exchange Commission (SEC) reviews filings and often issues comment letters requesting additional information or clarification. It is possible that questions from regulators contributed to the inclusion of the new language. However, confirmation may not come until those comment letters are released publicly after the IPO process moves forward.

The expanded discussion regarding water resources was not the only adjustment made in the amended filing. SpaceX also disclosed plans to reserve up to 5% of the shares offered in the IPO for employees and individuals connected to company executives. In addition, the filing now cautions investors that SpaceX could issue a substantial number of additional shares in future transactions after the IPO. The company notes that such actions could dilute existing shareholders’ holdings and may signal a potential future strategic deal, including a merger with Tesla.
