Tesla's Gigafactory Texas Set to House Huge Optimus V4 Robot Production Line

Tesla has confirmed that its Gigafactory Texas will be the site of an ambitious new production line for the next-generation Optimus V4 humanoid robot, with plans for a massive manufacturing scale-up that eclipses initial pilot efforts. The announcement comes from remarks made by Elon Musk on social media platform X, underscoring Tesla’s accelerating push into robotics and advanced automation.

Mass Production Moves to Texas

While Tesla’s initial Optimus robot lines are being built and tested at the Fremont factory in California, Musk revealed that Optimus V4 production will shift to Gigafactory Texas with much higher volume than before. The Texas facility is expected to significantly outpace the Fremont pilot line, establishing a major industrial hub for humanoid robot manufacturing.

At the 2025 Annual Shareholder Meeting, Musk outlined an aggressive vision: starting with a line capable of 1 million robots per year at Fremont, followed by an even larger production line in Texas that could eventually aim for 10 million units annually, a figure that, if reached, would represent an unprecedented scale in robotics production.

I predicted S and X would be discontinued.

Still sad to see them go.

I’m a bit surprised they’re building Optimus in Commiefornia. https://t.co/ikLurHYQt3

Why This Expansion Matters

Optimus is designed to be a general-purpose humanoid robot capable of learning tasks by observing humans or being shown how to perform tasks through demonstration or instruction. Tesla executives believe that such robots could have a transformational impact on industries and even broader economic metrics in the long term. Elon Musk has said Optimus has the potential to significantly influence sectors ranging from manufacturing to domestic assistance.

Having a dedicated production line for Optimus V4 at Gigafactory Texas, Tesla’s sprawling mega-factory near Austin, signals the company’s confidence in scaling up from early prototypes toward true high-volume robot manufacturing. This move mirrors Tesla’s historical strategy with electric vehicles: begin with smaller pilot runs and then expand into larger, highly automated facilities to support widespread commercialization, a model that has helped its vehicle business grow.

Conclusion

Although detailed timelines and production targets for Optimus V4 have not been publicly confirmed beyond Musk’s commentary, the commitment to building the next-generation robotics line in Texas reflects Tesla’s broader mission to lead not just in electric mobility but also in advanced machine learning, robotics, and automation. The future of Optimus and its role in Tesla’s product portfolio could become one of the defining elements of the company’s strategy in the coming decade.
