SpaceX has filed for a property tax abatement in Grimes County, Texas, for a semiconductor fabrication facility. The initial phase of the "Terafab" project is estimated to cost $55 billion, with the total investment potentially reaching $119 billion upon completion of all planned expansions. The facility is intended to manufacture chips for AI, Tesla's vehicles and robots, and SpaceX's space-based computing needs. A public hearing on a property tax abatement agreement for the project is scheduled for June 3.
The proposed site for the Terafab is the Gibbons Creek Reservoir in rural Texas, approximately 90 miles northeast of Austin. This location was formerly a coal-fired power station and is now considered a brownfield site. The project represents a significant move toward vertical integration for Musk's ventures, aiming to reduce reliance on external chip suppliers. Elon Musk has previously stated that the project is an "existential necessity" to ensure sufficient chip supply for the rapid growth of AI systems.
The Terafab project is a joint effort involving SpaceX, Tesla, and xAI. Initial reports in March indicated a $20 billion price tag, but the recent filings reveal a substantially larger investment. SpaceX confirmed in March that it would handle high-volume chip manufacturing, while Tesla would operate a smaller research and development pilot line at its Austin campus. Intel has been announced as a partner for the project, with plans to utilize Intel's 14A manufacturing process.
The scale of the proposed investment far exceeds the $52.7 billion allocated by Congress for the entire U.S. semiconductor industry through the CHIPS Act. Analysts had previously estimated the cost of such a facility to be around $45 billion. Beyond the capital expenditure, the project faces challenges in securing specialized technical talent.
SpaceX is also preparing for a significant initial public offering (IPO), which is anticipated to be the largest in history. In preparation for the IPO, SpaceX has also filed for enhanced protections under Texas law, intended to deter hostile takeovers and activist investor campaigns. These legal measures, combined with internal company provisions, aim to solidify Elon Musk's control over the company. The company's S-1 filing indicates that these protections are expected to discourage coercive takeover practices and inadequate bids, requiring potential acquirers to negotiate directly with SpaceX.
The proposed Terafab facility would produce two main types of chips: lower-power processors for vehicles and robots, and higher-performance chips for space-based computing. Musk envisions the facility supporting massive computing capacity both on Earth and in orbit. He previously stated that Terafab would eventually produce enough chips for 1 terawatt of compute each year.
The project's proposed location in Grimes County is a rural area that previously hosted a coal-fired power station operated by the Texas Municipal Power Agency until 2018. Charah Solutions acquired the property in 2021 for demolition and remediation, subsequently selling it in parcels to undisclosed buyers.
The Grimes County Commissioners will consider the property tax abatement for the project on June 3. Public comments regarding the project have been mixed, with some residents expressing opposition and others supporting the potential job creation and economic benefits.
