Tesla officially broke ground on the $3.6 billion Phase II expansion of Gigafactory Nevada on July 6, 2026. The project includes the construction of two major facilities: a dedicated high--volume production line for the Tesla Semi and a 100 GWh 4680 battery cell factory. This expansion is a strategic move to scale the company's heavy--duty trucking division and enhance vertical integration of its battery supply chain, aiming to reduce long--term production costs.
