Three DeSoto County residents filed a federal class action on June 9 against xAI, SpaceX, and xAI subsidiary MZX Tech LLC in the Northern District of Mississippi [CASE NO. PENDING], alleging that gas-fired turbines at xAI's Southaven power facility subject more than 10,000 nearby residents to near-constant noise and vibration. The complaint asserts claims for public nuisance and negligence and seeks damages for emotional distress and diminished property values, disgorgement of profits, and injunctive relief that could force operational changes at the facility. Elon Musk is not a named defendant.
The complaint frames the case in categorical terms, alleging that the AI buildout is "wreaking havoc on communities across the United States." Plaintiffs' counsel Robert Wiygul of Waltzer Wiygul & Garside described the harm as an around-the-clock invasion of the home: residents near the facility at 2875 Stanton Road South report jet-engine-level sound that prevents sleep, in a neighborhood of houses, churches, and schools.
The facility at the center of four legal fronts
This is not an isolated filing. The same plant is now the subject of overlapping proceedings that together sketch the emerging shape of AI infrastructure litigation.
The NAACP and its Mississippi State Conference sued xAI and MZX Tech in April under the Clean Air Act's citizen suit provision (NAACP v. X.AI, No. 3:26-cv-00074-MPM-JMV, N.D. Miss.), alleging the companies built and expanded the plant without preconstruction or Prevention of Significant Deterioration permits. Court filings in that case document the buildout with unusual precision: MZX Tech acquired the Southaven property in July 2025, had 18 turbines powering xAI's Colossus 2 data center by November, 27 by December, and 33 by April 2026, with six added after the NAACP served its notice of intent to sue. At 33 turbines, the plaintiffs' engineering analysis puts potential emissions at roughly 2,500 tons of nitrogen oxides per year, which would make the plant the largest industrial NOx source in the 11-county Memphis metro area by more than a factor of three. Only the 14 smallest turbines carry smog controls.
The NAACP's pending preliminary injunction motion asks the court to halt operations entirely until permits issue. The defense rests heavily on a two-paragraph 2025 letter in which Mississippi regulators deemed the turbines exempt from permitting as "mobile" and "temporary." The plaintiffs' response is blunt: these are units up to 100 feet long weighing as much as 400,000 pounds, set on concrete pads and hard-plumbed to gas, water, and electrical lines. A power plant, in their framing, does not become a mobile source because it arrived on a flatbed.
The Department of Justice signaled last month that it may intervene in the NAACP case, citing federal policy interests in AI infrastructure and the administration's stated commitment to American AI dominance. Its deadline to decide is June 15, six days after the nuisance class action hit the docket. A separate state-level appeal challenges the air permit Mississippi issued in March for a planned permanent 41-turbine fleet at the same site. Four fronts, one address.
Why this matters for the plaintiffs' bar
AI litigation to date has concentrated on outputs: copyright, defamation, and product liability theories built around what models say and generate. This case marks the arrival of the other half of the docket, the physical externalities of the infrastructure itself. Noise, air emissions, water demand, and property devaluation around data centers and their captive power plants are classic nuisance and toxic tort territory, and the buildout is national. xAI alone invested more than $20 billion at Southaven with the backing of Mississippi's governor, and hyperscale projects with self-generated gas power are replicating across the South and Midwest, frequently in communities with limited regulatory leverage and air quality already graded failing.
The Southaven cluster will be an early test of three questions that matter well beyond this docket. First, whether nuisance class actions can reach AI operators directly, with disgorgement of profits as a remedy that scales with the defendant rather than the harm. Second, how courts weigh a federal government openly invested in AI dominance against the property rights of the people living next to the buildout, a tension the DOJ's potential intervention puts squarely on the record. Third, whether the parent-subsidiary structure holds up: xAI operates through MZX Tech and is now itself under SpaceX ownership, and the NAACP's briefing already cites authority for direct parent liability where the parent controls a facility's environmental decision-making.
For mass tort practices, the practical read is simpler. Every hyperscale data center campus with on-site generation is a potential defendant cluster, every fenceline community is a potential class, and the Southaven filings are about to produce the first body of rulings on how these claims survive motions practice. This corner of the docket is worth watching from the first docket entry, because the next one will not be in Mississippi.
