SpaceX Wins $119B Texas Chip Deal as Musk Bypasses Taiwan Foundries

SpaceX secured a 100% property tax abatement from Grimes County commissioners on June 3 for a $119 billion semiconductor fabrication facility—the largest announced fab investment in US history and a strategic pivot into domestic chip manufacturing that bypasses traditional Taiwan-based supply chains.

The 4-1 vote came after a contentious public hearing where over 100 residents warned of water strain, power grid overload, and the permanent loss of rural character in the 34,000-person county. The project, structured as a joint venture between SpaceX, Tesla, and xAI, will supply chips for Starlink satellites, Tesla vehicles, xAI orbital data centers, and Optimus humanoid robots, according to Basenor. Intel is positioned as the manufacturing partner for the Intel 14A process node, per TechCrunch.

The approval marks a defining moment in the US semiconductor onshoring campaign. The $119 billion figure—if fully realized—exceeds TSMC’s Arizona expansion, which grew from $12 billion to $165 billion and represents the largest foreign direct investment in US greenfield history, data from TSMC shows. SpaceX’s Terafab now stands as the largest announced domestic fab investment, dwarfing prior commitments by Intel ($100 billion-plus), Micron ($100 billion proposed), and Texas Instruments ($60 billion).

Why SpaceX Is Building Its Own Foundry

The move reflects a structural shift in how space and AI infrastructure companies approach chip supply. Musk’s empire faces capacity constraints at TSMC and Samsung—foundries already stretched thin by Apple, Nvidia, and hyperscaler demand. Ben Bajarin, a chip analyst at Creative Strategies, told CNBC that SpaceX would struggle to secure priority at TSMC given existing commitments. Vertical Integration solves the problem: controlling the entire supply chain from design to fabrication eliminates dependence on Taiwan-based capacity and insulates against geopolitical risk.

The joint venture structure spreads cost and demand across three entities with distinct chip needs. Starlink satellites require radiation-hardened processors. Tesla’s autonomous driving stack demands edge AI inference chips. xAI’s orbital data centers—a novel architecture placing compute in low Earth orbit to reduce latency for AI training—require custom accelerators. Optimus robots add another volume driver. Together, these applications create the sustained demand necessary to justify a $119 billion fab, which carries a 15-year investment horizon.

The CHIPS Act Backdrop

The CHIPS Act allocated $39 billion for semiconductor manufacturing, catalyzing a broader onshoring wave. US companies have announced $645.3 billion in semiconductor investments across 140-plus projects in 30 states as of May 2026, according to the Semiconductor Industry Association. The US produced only 10% of global chips in 2024, down from 37% in 1990. China, meanwhile, is pursuing 7-nanometer and 5-nanometer node advancement and alternatives to ASML’s extreme ultraviolet lithography systems despite US export controls, per industry analysis.

SpaceX’s timing aligns with a record IPO planned for June 2026 at a $1.75 trillion valuation. The company aims to price shares at $135 to raise $75 billion, according to Yahoo Finance. The Terafab tax abatement strengthens the equity story by demonstrating strategic control over a critical input—chips—while the $20 million annual payment to Grimes County provides fiscal cover.

The Rural Backlash

Local opposition was intense. More than 100 speakers at the June 3 hearing warned of water and power infrastructure strain, wildlife habitat destruction, and the irreversible transformation of a county defined by sprawling ranches and dark skies. One resident told reporters the commissioners had “sold out Grimes County,” according to coverage from KBTX. The proposed site near Gibbons Creek Reservoir sits in an area valued for its quiet agricultural character—qualities incompatible with a facility that will eventually employ thousands and consume vast amounts of water and electricity.

Grimes County’s experience foreshadows tensions that will recur across onshoring sites. Semiconductor fabs require enormous infrastructure: multi-billion-gallon annual water usage, gigawatt-scale power demand, and heavy construction for years before a single chip ships. Rural counties offer land and tax incentives but lack the infrastructure and political constituencies to absorb industrial-scale development without friction. The promise of jobs and tax revenue—Musk’s $20 million annual payment plus employee income taxes—provides fiscal justification but does little to address concerns about irreversible environmental and cultural change.

What to Watch

The critical next steps are permitting and groundbreaking dates, which will reveal whether the $119 billion commitment is front-loaded or phased over decades. Intel’s formal announcement of its manufacturing role will clarify technology transfer terms and capacity allocation. SpaceX’s IPO performance in June will determine whether capital markets validate the vertical integration thesis or view it as overreach. Finally, watch for similar tax abatement battles in Arizona, Ohio, and New York—states where CHIPS Act projects are advancing through rural and exurban counties with limited industrial experience. Grimes County’s 4-1 vote may be the template: fiscal pragmatism wins, but opposition hardens as the scale of transformation becomes tangible.
