Fluidstack Breaks Ground on $4B Cameron County Data Center Campus
Fluidstack has broken ground on the first phase of a $4 billion AI data center campus in unincorporated Cameron County, Texas, after Cameron County issued a worksite permit allowing site clearing, grading, and utility installation to begin, the Rio Grande Guardian reports.
The 1,100-plus-acre campus sits east of FM 509 and west of FM 106, near Valley International Airport in Harlingen and the Port of Harlingen. Fluidstack says the first phase will generate more than 2,500 construction jobs and several hundred permanent technical roles, with no county tax abatements or incentives attached to the project. Cameron County Judge Eddie Treviño Jr. confirmed the worksite permit covers preliminary ground development, including access roads, parking, and stormwater retention ponds, ahead of a separate permitting step for vertical construction.
The project comes with several binding infrastructure commitments the company says it will fund directly rather than pass on to ratepayers. Cooling uses a closed-loop system with a tank capacity smaller than an Olympic swimming pool, supplied by the East Rio Hondo Water Supply Corporation and recycled rather than drawn from municipal supply. Fluidstack says it will cover all energy and transmission infrastructure costs itself, subject to Public Utility Commission of Texas and ERCOT audit protocols, and has committed to a 60-decibel noise cap at the property line.
Founded in 2017 and headquartered in New York, Fluidstack builds and operates dedicated GPU infrastructure for AI labs and closed a $1.5 billion funding round this year at an $18 billion valuation, alongside a previously announced multi-year capacity agreement with Anthropic.
What It Means for Subcontractors
Fluidstack says it is prioritizing Rio Grande Valley workers for construction, electrical, and skilled trades roles that don’t require a four-year degree, with hiring for the 2,500-plus construction jobs starting now ahead of vertical construction. Electrical and mechanical subs bidding data center work in South Texas should treat the Cameron County permit conditions, closed-loop cooling, self-funded grid infrastructure, and strict noise limits as the emerging template other Texas counties may require on future AI data center campuses. Site work, access roads, and utility installation are already underway, meaning trade packages for the vertical build phase are likely to open within the coming months.
