SpaceX officially filed for its initial public offering on Wednesday, and its lengthy prospectus revealed a significant investment in gas turbines to power the company’s AI data centers. This disclosure comes amid ongoing litigation over its use of the air-polluting generators. Elon Musk’s xAI, which merged with SpaceX in February, was sued by the NAACP in April. The organization, represented by the Southern Environmental Law Center and Earthjustice, alleges that xAI and its subsidiary, MZX Tech, illegally operated 27 natural gas turbines without an air permit at its data center power plant in Southaven, Mississippi. But that hasn’t discouraged xAI from installing more turbines, according to reports published last week. Apparently, the company added 19 of them to its fleet between late March and early May. Now, SpaceX’s S-1 filing shows that the company is digging its heels in further. It states that on April 30, SpaceX entered a purchase agreement with an unspecified company to purchase approximately $2 billion worth of mobile gas turbines and related equipment. The document also indicates that during a period of three months ending on March 31, SpaceX executed purchase agreements with an unspecified company to acquire an additional $925 million worth of turbines through 2029.
