• The proposed Terafab facility in Grimes County aims to produce a staggering one trillion watts of computing power annually.
• SpaceX is leading an initial $55 billion investment push for a massive chipmaking campus at the Gibbons Creek Reservoir site.
• The project would manufacture two distinct chip types: one for Tesla’s vehicles and robots, and another built specifically for space applications.

SpaceX has unveiled a bold plan to anchor a new era of domestic semiconductor production in rural Texas, with an initial $55 billion proposal to build a sprawling chip fabrication campus in Grimes County. The project, internally codenamed Terafab, would be located at the retired Gibbons Creek Reservoir, transforming an old power plant site into what could become one of the most advanced computing hardware hubs in the world. County commissioners are scheduled to vote next month on a property tax abatement agreement, a move that local officials hint could fast-track construction as early as next year.

During a live stream on his social media platform X, Elon Musk revealed that the facility’s annual output is targeted at one trillion watts of compute capacity—a figure more commonly associated with national power grids than microchip production.

The sprawling campus, which Musk later clarified would consist of two separate fabrication plants, is expected to cover approximately 100 million square feet. While Musk offered no specific investment breakdown during the 30-minute broadcast, independent estimates from multiple outlets have pegged the total project value at roughly $25billion,thoughSpaceX’s\; ownpreliminary\; spendingcommitmentstandsat$55 billion.

The strategic logic behind Terafab appears twofold. One production line will focus on custom chips destined for Tesla’s electric vehicles and its developing humanoid robot line, Optimus. The other will manufacture high-radiation-tolerant, high-powered processors designed exclusively for spacecraft and orbital systems, directly feeding SpaceX’s Starlink and Starship programs. By co-locating automotive, robotics, and space-grade chip production, Musk is effectively betting on vertical integration at an unprecedented scale, bypassing traditional supply chains that have left even major automakers waiting months for essential components.

What makes this announcement unusual is its timing. Rather than seeking federal CHIPS Act funding upfront, Terafab appears to be self-financed in its early stages, with the tax abatement request serving as the primary public incentive. Grimes County, historically reliant on agriculture and energy production, now stands at the center of a potential industrial revolution that could bring thousands of high-wage technical jobs to a region better known for its reservoir and coal plant history.

Environmental groups have already begun quietly reviewing the Gibbons Creek location, noting that repurposing an existing industrial site may reduce the ecological footprint compared to greenfield development. If approved, Terafab would not only rival Taiwan’s and Arizona’s leading chip foundries but also reorient the geopolitics of advanced computing around a single Texas county.
