sulphur springs v. vistra -- land restriction antitrust dispute

case overview

Case	Sulphur Springs v. Luminant/Vistra
Court	Texas state court (Hopkins County)
Filed	2025
Parties	City of Sulphur Springs + MSB Global v. Luminant/Vistra
TX AG Involvement	Amicus brief + antitrust investigation
Status	Active — preliminary injunction in place; dismissal motion heard July 2026

background

vistra subsidiary luminant donated former lignite mine land to sulphur springs with a restrictive covenant prohibiting power generation or storage. sulphur springs then agreed with msb global to build 30 ai data centers on the land. vistra sent a cease-and-desist in september 2025.

sulphur springs and the texas attorney general argue the restrictive covenant creates an illegal “energy monopoly” violating state antitrust law. ag ken paxton’s office filed an amicus brief supporting the city and announced an investigation into luminant for including similar restrictions in 100+ other deeds across texas.

vistra filed counterclaims arguing the deed restriction is enforceable. a judge denied sulphur springs’ motion for early resolution in february 2026.

significance

this case has implications for data center siting across texas, particularly on former industrial/mining land. if the restrictive covenants are found to violate antitrust law, it could open up significant acreage for data center development.

update: injunction and pending dismissal motion

two developments this page did not previously capture:

the february 2026 order that denied sulphur springs’ motion for early resolution also imposed a preliminary injunction barring new construction or development on the disputed land pending trial.
in july 2026 the court heard vistra’s motion to dismiss 6 of the city’s 11 claims, including the fraud counts. no ruling had issued as of the reporting consulted — unconfirmed, needs a docket check.
