Tesla (NASDAQ: TSLA) and SpaceX Plan $16.8 Billion Texas Chip Factory Spanning 100 Million Square Feet

Tesla and SpaceX confirmed plans Thursday, August 6, 2026, to build a massive semiconductor factory called Terafab in Grimes County, Texas. The initial investment stands at $16.8 billion, with the facility spanning more than 100 million square feet. Elon Musk, CEO of both companies, called it “the largest and most valuable building on Earth by far.” Terafab will produce chips for Tesla’s Optimus robots, Cybercabs, and SpaceX’s planned space-based data centers.

Terafab’s Scale Dwarfs Every Existing Chip Facility

Terafab’s confirmed footprint would make it the largest manufacturing building ever constructed, surpassing every current record holder by a wide margin.

• The world’s current largest building, Chengdu’s New Century Global Center, spans just 18.9 million square feet.
• Terafab’s 100 million square feet would exceed that by more than five times.
• Tesla’s existing Gigafactory Texas covers roughly 10 million square feet by comparison.

Combined, the Pentagon, Apple Park, Mall of America, and Giga Texas total just 25.04 million square feet. Terafab alone would dwarf all four of those landmark buildings put together.

Why Tesla and SpaceX Need Their Own Chip Supply

Tesla (NASDAQ: TSLA) and SpaceX (NASDAQ: SPCX) say their combined future compute demand already exceeds what global chip suppliers can provide. That gap is driving this unprecedented investment.

• SpaceX estimates combined chip demand will exceed 1 terawatt of compute capacity.
• That figure surpasses current total global semiconductor production output.
• The facility will house logic, memory, packaging, and testing under one roof.

This vertical integration mirrors Musk’s broader strategy across Tesla and SpaceX, reducing dependence on external chip suppliers like TSMC and Nvidia for future AI and robotics workloads.

Texas Incentives and Local Pushback Shaped the Deal

Texas offered substantial financial incentives to secure Terafab, while some Grimes County residents raised concerns during the process. Both sides of that story matter for understanding the project’s path forward.

• The state extended a $30 million Texas Enterprise Fund grant to SpaceX.
• Grimes County commissioners approved a 100% property tax abatement in June 2026, voting 4-1.
• Governor Greg Abbott called Terafab a “first-of-its-kind” facility that will “accelerate chip production.”

A county meeting Wednesday, August 5, drew hundreds of residents questioning the tax incentives and project transparency, just one day before the official announcement.

Water Use and Job Creation Commitments

Terafab’s planners addressed a common concern with large data-center and chip-fab projects: local water strain. The companies outlined a specific alternative sourcing plan.

• Water will come from the Gibbons Creek Reservoir, not local groundwater supplies.
• The facility is expected to create at least 3,000 jobs.
• Workers will be drawn from Grimes County and neighboring Brazos County.

This $16.8 billion figure covers only Terafab’s first phase, with some industry estimates suggesting total investment could eventually reach $119 billion.

Tesla and SpaceX are dropping $16.8B on "Terafab," their own chip factory in Texas.

A leading edge fab runs $20B+ and takes years to build so this is them buying a permanent spot at the front of the line instead of waiting behind Apple and Nvidia for TSMC's booked out capacity.…

What Investors Should Watch Going Forward

Tesla shares reflect growing investor interest in Musk’s push toward vertical chip integration across his companies. SpaceX, meanwhile, filed for an IPO in May 2026.

• That IPO filing described Terafab as a “general framework” with no binding financial commitments.
• Either Tesla or SpaceX could still walk away from the project under current terms.
• Construction timelines and specific chip output targets remain unconfirmed as of this announcement.

This flexibility gives both companies room to scale Terafab’s investment up or down based on actual chip demand trends.

Our Take

Terafab represents one of the most ambitious vertical-integration bets in Tesla’s history, tying chip supply directly to demand from robotics and space computing. With no binding commitments yet, execution risk remains real despite the scale of Thursday’s announcement.
