Tesla's Terafab Chip Fab to Span 100M Sq Ft in Texas

**Implied Volatility / Movement:** Tesla ($TSLA+WL) is down 27.17% year-to-date, facing headwinds from a capital expenditure surge and negative Q2 free cash flow.

Mega-cap U.S. equity indices saw modest gains, with the S&P 500 adding 0.25%, the Dow Jones Industrial Average up 0.30%, and the Nasdaq 100 increasing by 0.24%.

Elon Musk's Terafab project, a joint venture between Tesla, SpaceX, and xAI, is poised to become one of the world's largest manufacturing facilities, spanning over 100 million square feet in Grimes County, Texas. This massive chip fabrication plant, confirmed on August 6, 2026, is designed to produce a terawatt of computing power annually, intended for applications such as humanoid robots, self-driving vehicles, and orbital data centers. The facility's scale is projected to be roughly 36 times the size of the Empire State Building's office space.

While the confirmed first phase of Terafab is valued at $16.8 billion, a SpaceX filing indicates the total project cost could eventually reach $119 billion across multiple phases. The project aims to draw cooling water from the former Gibbons Creek Reservoir, addressing local community concerns regarding groundwater usage. Intel has also joined the Terafab venture with unspecified terms, while TSMC and Samsung are already supplying Tesla's near-term chip needs through separate agreements.
