Giga Texas transformed the Austin landscape. Elon Musk thinks Terafab could be about 10x the size.

Tesla’s upcoming chip plant, Terafab, is expected to dwarf anything the company has built before.

For comparison, its flagship factory, Gigafactory Texas, comprises roughly 10 million square feet across multiple floors on a 2,500-acre campus. Here’s a time-lapse of its construction from Planet Labs:

While Tesla hasn’t disclosed Terafab’s exact size, CEO Elon Musk has suggested it could be an order of magnitude larger — on the scale of 10x Giga Texas — and would require “thousands of acres.”

He’s also compared it to Samsung’s Texas semiconductor plant, which is expected to be around 8 million square feet. By Musk’s estimate, Terafab could be roughly 12x that size, close to 100 million square feet — or nearly 2,000 football fields.

Early speculation pointed to a structure shown near Giga Texas in Tesla’s presentation, but Musk later clarified that the building, about 2 million square feet, was “just the little advanced technology fab, where we will be iterating on chip designs.”

“We couldn’t possibly fit the Terafab on the GigaTexas campus,” Musk wrote on X. “It will be far bigger than everything else combined there.” He said several locations are currently under consideration for it.
