The DOJ submitted a memorandum supporting xAI in response to a lawsuit filed in April. According to a report by Wired, the DOJ explained that the claims made by the NAACP would result in cutting off the power supply that supports AI innovation and would impact the Department of Defense's military operations. Grok is reportedly one of four AI models that support "mission-critical operations," such as attacks on Iran.

US Department of Justice Supports xAI in Gas Turbine Lawsuit Citing National Security

xAI utilizes "mobile" gas turbines mounted on trailers at its Colossus and Colossus 2 data centers. The company argues that because they are trailer-mobile, they are exempt from Mississippi's air pollution regulations for one year. Conversely, the Southern Environmental Law Center, which initiated the lawsuit, counters that trailer-mounted units should be considered stationary and thus regulated under federal law.
The NAACP points out that air quality in the region has deteriorated since the data centers began operating. Since last year, the number of turbines has more than doubled, and major pollutants such as PM2.5 and formaldehyde have increased. These substances are linked to asthma, cardiovascular disease, and cancer risks.
xAI, which has become a division of SpaceX, is expected to further expand its power generation facilities. SpaceX's IPO filing explicitly states that it will purchase $2.8 billion worth of gas turbines over the next three years. At least $2 billion of that amount is planned to be allocated to "mobile gas turbines."
