Grimes County, Texas, just handed SpaceX a full property tax waiver lasting 35 years for a planned $55B semiconductor manufacturing facility called Terafab. The county’s commissioners court approved the deal on a 4-1 vote, greenlit after a public hearing on June 3, 2026, where local residents voiced concerns about environmental impacts and the sheer scale of tax incentives being offered to one of the world’s most valuable private companies.
In exchange for the 100% property tax abatement, SpaceX will pay an upfront fee of $10M and annual payments of $20M over the 35-year term. Quick math: that’s $710M in total payments to the county, which sounds like a lot until you remember the alternative was collecting property taxes on a facility that could eventually represent $119B in total investment.
What Terafab actually is
The facility is a joint effort involving SpaceX, Tesla, and xAI, all companies under Elon Musk’s expanding empire. Terafab is designed to be one of the world’s largest chip fabrication plants, producing advanced AI chips, logic and memory semiconductors, and packaging components.
Tesla needs custom silicon for its autonomous driving systems and humanoid robots. xAI needs compute power for its Grok models. SpaceX has its own chip requirements for satellite communications and spacecraft systems.
Construction is expected to generate approximately 2,000 jobs in the area, a significant number for a rural county near College Station and the greater Houston region.
Why locals aren’t celebrating
Grimes County is not exactly Silicon Valley. It’s a rural community where the sudden arrival of a mega-scale industrial facility raises real questions about water usage, land transformation, infrastructure strain, and whether $20M a year in payments adequately compensates for what residents stand to lose.
The 4-1 vote suggests the opposition wasn’t trivial. One commissioner broke ranks, reflecting concerns that were clearly present in the public hearing. The bet from commissioners is that indirect economic activity, job creation, and the halo effect of having a world-class semiconductor facility will more than compensate for the forgone property tax revenue over 35 years.
What this means for investors
The Terafab project signals a structural shift in how the largest tech companies think about chip supply chains, bringing production onshore and under direct control rather than outsourcing fabrication to Asian foundries.
There’s also the question of whether 2,000 jobs justifies the incentive package from a pure economic development standpoint. That works out to roughly $27.5M in initial investment per job created. The real payoff for Grimes County depends entirely on whether the facility attracts a broader ecosystem of suppliers, housing development, and service businesses that multiply the direct employment figures.
