More than $110 billion in projects are underway or announced in the Rio Grande Valley in 2026. SpaceX is seeking tax abatements for a $24 billion xAI data center planned on a 444-acre property adjacent to the Port of Brownsville.
Why it matters
The concentration of energy, defense and data center investment could reshape the economy of South Texas and draw new jobs and infrastructure to the region. Incentive requests from local governments will determine how much of that investment is shared with the public.
The Port of Brownsville has $64 billion in investment underway and about 40,000 acres available for development, but the extraction does not state how much of the announced $110 billion total is committed versus proposed. Whether the $24 billion xAI project and other planned facilities proceed as scheduled remains unresolved.
The players
SpaceX
SpaceX is the aerospace company founded by Elon Musk that operates the Starbase launch complex in South Texas and is seeking abatements for the xAI data center.
Port of Brownsville
The Port of Brownsville is the only deepwater port on the U.S.-Mexico border and the largest land-owning port authority in the country.
Saronic Technologies
Saronic Technologies is a defense shipbuilding company seeking incentives to build a $3.2 billion military shipyard at the port.
Fluidstack
Fluidstack is a company building a 1.5 gigawatt data center near Harlingen as part of a $4 billion investment in the Valley.
Soluna Holdings
Soluna Holdings is a company operating data centers in Willacy County, one of the Valley's growing data center sites.
The details
SpaceX will request tax abatements from the Starbase City Commission and the Cameron County Commissioners Court for a $24 billion xAI data center. Fluidstack is investing $4 billion to build a 1.5 gigawatt data center near Harlingen, and Karadeniz Holdings is investing $3 billion to construct floating data centers called dataships.
Timeline
March: President Trump announced the America First Refining refinery at the Port of Brownsville.
August: U.S. Energy Secretary Chris Wright visited the region.
September: Vance and Gov. Greg Abbott attended the Saronic Port Alpha shipyard groundbreaking.
In the coming weeks: SpaceX goes before the Starbase and Cameron County commissions for tax abatements.
Tech Race
The $24 billion xAI data center extends SpaceX's Starbase footprint from rocket launches into large-scale AI computing, placing it alongside Fluidstack's 1.5 gigawatt facility near Harlingen as competing AI infrastructure bets in South Texas. Together these projects position the Rio Grande Valley as a new hub for AI data capacity in the state.
Residents of the Rio Grande Valley may see changes in local tax revenue and job availability as tax abatements for the xAI data center are decided. Households in the region should watch county commission agendas for votes that determine how much public funding is committed to these projects.
The takeaway
Large industrial and data center projects can bring substantial investment, but the public benefit depends on the incentives granted and the projects that are actually completed. Tracking commission votes is the clearest way to follow what is committed.
What happens next
SpaceX goes before the Starbase City Commission and the Cameron County Commissioners Court in the coming weeks to seek tax abatements for the $24 billion xAI data center.
