More than 10,000 residents of Southaven and Horn Lake could be covered by the proposed class, which seeks damages and a court order to abate the noise.

This article describes a class action complaint. The statements below are unproven allegations. X.AI Corp., Space Exploration Technologies Corp. and MZX Tech LLC have not been found liable, there is no certified class, and there is nothing to claim at this time. This page is informational and is not legal advice.
What Is This About?
Three residents of Southaven, Mississippi have filed a proposed class action accusing xAI, SpaceX and MZX Tech LLC of blanketing their suburban neighborhoods with round-the-clock industrial noise from the gas-fired turbines that power xAI's artificial intelligence data centers. The complaint, Haley v. X.AI Corp., was filed June 8, 2026 in the U.S. District Court for the Northern District of Mississippi (Case No. 3:26-cv-00148), and centers on the power plant the defendants operate at 2875 Stanton Road South in Southaven — referred to in the complaint as the "Southaven Plant."According to the complaint, the defendants began running "temporary" gas turbines at the site in mid-2025 to power xAI's Memphis-area data centers — including the Colossus facilities where the company trains and runs its Grok AI models — and have since grown the installation from 3 turbines to 57. The plaintiffs allege the turbines emit a continuous mix of high-pitched squealing, engine roar, low-frequency rumbling and tonal humming that travels into homes in Southaven and neighboring Horn Lake 24 hours a day, disrupting sleep and making it impossible to enjoy their homes and yards. The defendants have not responded to the allegations in court, and none of the claims have been proven.
What the Complaint Alleges
The complaint alleges that in less than a year the defendants increased the number of gas-fired turbines at the Southaven Plant by 1,800% — from 3 to 18 to 27 to 57 — while continuing to describe them as "temporary." In March 2026, the Mississippi Department of Environmental Quality approved a permit for 41 additional "permanent" turbines at the site, a decision that is now being challenged in a separate appeal by environmental groups.Residents allege the resulting noise is "omnipresent and inescapable," penetrating the walls of their homes even with windows closed, and that it can be felt as physical vibration. The complaint describes decibel readings as high as 70 dBA at residents' property lines — the limit set by Southaven's noise ordinance for normal industrial operations — and says the low-frequency component of the noise is not fully captured by standard A-weighted measurements. Plaintiffs claim the constant noise has caused sleep disruption, stress, anxiety, headaches, nausea and tinnitus, and has diminished the value of homes near the plant. The complaint expressly does not assert personal injury claims; it describes these as nuisance-level harms.
The plaintiffs also allege the defendants knew the risk before they arrived: noise complaints have followed data centers and their power infrastructure around the country, and xAI's turbines at its Memphis Colossus site had already drawn community opposition and a notice of intent to sue from the NAACP over Clean Air Act issues before the Southaven site was purchased. Despite months of resident complaints, petitions, a packed public hearing where no one spoke in favor of the permit, and the Southaven mayor's own acknowledgment that "the noise has not been acceptable," the plaintiffs say the defendants have not meaningfully reduced it.

Who Are the Defendants?
The complaint names three defendants. X.AI Corp. is the artificial intelligence company behind the Grok large language model. MZX Tech LLC is the entity that purchased the Southaven property in July 2025 and holds the site's air permit; the complaint alleges MZX was formed at xAI's direction, is managed by xAI, and shares its office address and personnel. SpaceX is named as xAI's alleged successor in interest: the complaint alleges SpaceX acquired xAI in February 2026, that Elon Musk — CEO of both companies — announced in May 2026 that xAI would be dissolved into "SpaceXAI," and that SpaceX now owns or controls the Southaven Plant. Those successor-liability allegations, like the rest of the complaint, are unproven.Who Would Be in the Proposed Class?
The complaint proposes a class of all individuals who resided in or owned residential property, at any time from August 2025 to the present, within a mapped area of Southaven and Horn Lake bounded by Stateline Road West to the north, U.S. Highway 51 to the east, Nail Road to the south, and a line one mile west of Horn Lake Road to the west. The plaintiffs allege more than 10,000 class members reside within that area. The precise class definition would be set by the court if and when it certifies the case. No class has been certified yet, so there is nothing for residents to file at this stage.What the Lawsuit Seeks
The proposed class action seeks compensatory damages for interference with the use and enjoyment of property, mental anguish and emotional distress, nuisance-level physical harms, and — for property owners — diminution in property value, along with punitive damages. The plaintiffs also ask the court for injunctive relief to abate the noise from the Southaven Plant "in a manner to be determined by experts." Whether any damages are awarded or operational changes are ordered would be decided by the court as the litigation proceeds.Read the Complaint

As a newly filed complaint, the case is at an early stage. The defendants will have an opportunity to respond, and the court will eventually decide whether to certify a class. Separately, the MDEQ air permit for the 41 permanent turbines faces its own appeal, and xAI's Memphis-area operations remain the subject of other environmental disputes. There is no settlement, no certified class, and no claim form — so there is nothing for residents to submit right now. We will update this page if the case is certified, dismissed, or resolved.Frequently Asked Questions
What does the xAI Southaven class action allege?
The complaint alleges that xAI, SpaceX and MZX Tech LLC operate dozens of gas-fired turbines at 2875 Stanton Road in Southaven, Mississippi to power xAI's nearby data centers, and that the turbines emit constant noise and low-frequency vibration into surrounding neighborhoods 24 hours a day. The plaintiffs bring claims of private nuisance, public nuisance, negligence, negligence per se under Southaven's noise ordinance, and negligent infliction of emotional distress. These are unproven allegations; the defendants have not been found liable.
Is there a settlement or money to claim?
No. This is a recently filed complaint. No class has been certified, there is no settlement, and there is nothing to claim at this time. The case must clear class certification before it could proceed on behalf of the proposed class.
Who would be in the proposed class?
The complaint proposes a class of all individuals who resided in or owned residential property, at any time from August 2025 to the present, within a defined area of Southaven and Horn Lake, Mississippi — bounded by Stateline Road West to the north, U.S. Highway 51 to the east, Nail Road to the south, and a line one mile west of Horn Lake Road to the west. The plaintiffs allege more than 10,000 people live within that area. The exact class definition would be decided by the court at certification.
What does the lawsuit ask for?

Why is SpaceX a defendant in an xAI lawsuit?
The complaint alleges that SpaceX acquired xAI in February 2026 and is xAI's successor in interest, succeeding to its assets, operations and liabilities, and that SpaceX now owns or controls the Southaven Plant. Those successor-liability allegations are unproven.
