Tesla or SpaceX: Who Benefits More From Terafab and How
SpaceX’s 247% AI segment growth and $93.5 billion cash pile give it more leverage than Tesla in allocating Terafab output.
- Tesla and SpaceX confirmed Terafab last week, a $16.8 billion semiconductor plant in Grimes County, Texas, designed as the largest chip manufacturing facility on the planet.
- SpaceX's 247% AI segment growth and $93.5B cash pile provide significantly more Terafab upside than Tesla, whose free cash flow turned negative at $1.09 billion and operating margin collapsed to 1.4%.
- Despite Tesla co-owning the facility, the project will utilize natural gas plants and large battery arrays rather than Tesla solar, which markets solar-plus-storage as an AI power solution.
- SpaceX holds $14.1B in signed cloud agreements and a pending $60B Cursor deal, making wafer allocation at Terafab the critical signal for its future compute capacity demands.
- Tesla needs Terafab to protect gross margins on millions of vehicles and eventually one million Optimus units annually, while SpaceX leverages the fab for Starlink and Starship avionics.

Tesla (NASDAQ: TSLA) And SpaceX Commit $16.8 Billion To Single Chip Plant As Annual Profit Sits At Just $3.8 Billion
Tesla (NASDAQ: TSLA) and SpaceX announced on August 6 that they will jointly spend $16.8 billion on the first phase of Terafab, a semiconductor manufacturing plant located in Grimes County, Texas. The scale of that commitment is striking when measured against Tesla’s financial performance over the past twelve months, during which the company reported net income of approximately $3.8 billion. In simple terms, the first phase of Terafab alone cost…
It’s not just Gina Rinehart who failed to make a killing on SpaceX
For the 28,000-plus Australian mum and dad punters, there hasn’t been much joy or excitement in the return on their investment.
Tesla and SpaceX want to make their own chips at a giant Texas plant to meet a joint demand higher than a computer teravatio
Musk's Terafab chip plant will run on gas, not Tesla solar
SpaceX confirmed it will power Terafab, its $16.8 billion chip megafactory in Texas, with its own natural gas power plants and “very large battery arrays.” Tesla solar isn’t in the plan. That’s despite Tesla being a partner on the project, and despite Tesla selling solar panels, Powerwalls, and grid-scale batteries built for exactly this kind of load.
