Tesla secured its largest-ever order for the Semi truck from freight technology firm WattEV. The deal includes 370 units valued at approximately $100 million.

This agreement marks the largest single electric truck order in California history. WattEV expects delivery of the first 50 units in 2026. The entire fleet will be operational by the end of 2027.

Tesla is currently scaling Semi production at its Nevada facility to meet higher 2026 output targets. More than 300 of these trucks will support a joint program at the Port of Oakland. WattEV will deploy Tesla’s Megawatt Charging Systems to provide rapid charging for the new fleet.
