Tesla and SpaceX have confirmed where they\u2019ll build Terafab, the semiconductor megafactory Elon Musk first teased in March. It\u2019s going to Grimes County, Texas, about an hour northwest of Houston.<\/p>\n

The companies put the initial phase at roughly $16.8 billion and said the finished site will span more than 100 million square feet, which they\u2019re calling the largest chip manufacturing facility on the planet.<\/p>\n

<\/p>\n

SpaceX laid out the plan in an update on its site Thursday, and Tesla echoed it on X. \u201cBoth Tesla & SpaceX will need far more chips than current & future global production can supply,\u201d Tesla wrote, pointing to a goal of \u201cproducing over 1 terawatt of compute per year.\u201d<\/p>\n

Terafab will be built in Grimes County, Texas<\/p>\n

In April, we broke ground on our research fab on the North Campus of Giga Texas \u2013 the precursor to Terafab.<\/p>\n

Both Tesla &\u00a0SpaceX will need far more chips than current &\u00a0future global production can supply.<\/p>\n

The pitch is vertical integration at a scale nobody has attempted. SpaceX says Terafab will combine logic, memory, packaging, and testing under one roof, producing chips for Tesla\u2019s Optimus robots and Cybercabs and for the \u201cspace-based data centers\u201d SpaceX wants to launch. The first phase is $16.8 billion from the two companies, with \u201cfuture expansion phases bringing total investment much higher.\u201d At least 3,000 people would work there, most of them local hires.<\/p>\n

The site has a backstory. Terafab will sit on the Gibbons Creek Reservoir, which used to cool a coal-fired power plant that shut down in 2018. SpaceX says it\u2019ll pull water from the reservoir rather than local groundwater, a nod to a Grimes County community that\u2019s already uneasy about water use and the data centers spreading across Texas.<\/p>\n

The price tag keeps moving<\/h2>\n

That $16.8 billion figure is not the number Musk led with. When Tesla and SpaceX first announced Terafab in March, the headline number was $25 billion<\/a>. Now it\u2019s a $16.8 billion \u201cinitial phase,\u201d with the rest left vague.<\/p>\n

And in May, SpaceX\u2019s own IPO paperwork undercut the pitch. The company\u2019s S-1 filing described Terafab as only a \u201cgeneral framework\u201d<\/a> with no binding commitments, no finalized IP split, and no obligation for either side to keep participating. A month before that, we reported that Tesla wasn\u2019t really going to build the fab itself, with Intel lined up to handle the actual manufacturing<\/a>.<\/p>\n

So the confident tweet naming a county sits on top of a paper trail that says a lot of this is still undecided.<\/p>\n

Tesla already has its chips coming from Samsung and TSMC<\/h2>\n

None of this is about Tesla\u2019s near-term supply, which is already contracted out. Samsung\u2019s Taylor, Texas fab is in production on Tesla\u2019s AI5 chip<\/a>, and last year Tesla signed a $16.5 billion deal with Samsung<\/a> to build its next-generation AI6 chip. TSMC covers the rest.<\/p>\n

That makes Terafab a much longer bet, tied to Musk\u2019s claim that his companies will eventually need more compute than the whole semiconductor industry can produce. It\u2019s the same \u201c1 terawatt of compute per year\u201d math he laid out when SpaceX absorbed xAI in February and started pitching orbital data centers.<\/p>\n

The scale claims are hard to square with anything that exists. 100 million square feet is more than ten times the floor space of TSMC\u2019s biggest gigafabs. TSMC is spending roughly $165 billion to build six fabs in Arizona, and those are a fraction of Terafab\u2019s stated footprint. No fab on Earth is built to output \u201ca terawatt of compute\u201d a year, because that number doesn\u2019t come from the chip industry. It comes from Musk\u2019s space ambitions.<\/p>\n

Electrek\u2019s Take<\/h2>\n

Terafab is more real today than it was in March. There\u2019s a county, a site, permits moving, and SpaceX reps sitting down with residents. That\u2019s more than a slide in a keynote.<\/p>\n

But the gap between the tweet and the fine print is still wide. Tesla and SpaceX are calling this \u201cthe largest chip manufacturing facility ever\u201d before pouring a foundation, while the same SpaceX told IPO investors three months ago that Terafab was a \u201cgeneral framework\u201d with no binding commitments. Both of those can\u2019t be fully true.<\/p>\n

The number that matters for Tesla shareholders is how much of that $16.8 billion, and the \u201cmuch higher\u201d that follows, lands on Tesla\u2019s balance sheet. Tesla already committed $16.5 billion to Samsung for chips it can build today, while its car business has stopped growing<\/a>. Pouring billions more into a terawatt of compute for robots and orbital data centers describes a very different company than the one most Tesla investors originally bought into.<\/p>\n

However, it fulfills Musk\u2019s long-stated argument that \u201cTesla is not an automaker anymore.\u201d<\/p>\n

As data centers put mounting pressure on the grid and electricity rates keep climbing, home solar and batteries are becoming basic infrastructure rather than a luxury. With electricity rates up almost 10% last year and expected to keep climbing, going solar is one of the best ways to protect yourself against rising costs. And with lease and PPA options, you can do it with zero upfront cost and start saving immediately. If you want to find the best deal, check out EnergySage<\/a>. It\u2019s a free service with hundreds of pre-vetted installers competing for your business, so you save 20 to 30% compared to going it alone. No sales calls until you pick an installer.
