Tesla Breaks Ground on Dedicated Optimus Factory at Giga Texas

AUSTIN, Texas — Tesla's dedicated factory for Optimus humanoid robots is officially under construction at Gigafactory Texas, with the first steel structure now standing and a second phase of land reclamation underway. Drone footage captured on May 27, 2026 by Giga Texas observer Joe Tegtmeyer shows the new building taking shape on the North Campus of the facility — a milestone that moves Tesla's most ambitious manufacturing project from blueprint to physical reality.

The new facility is expected to extend nearly the full length of the main Gigafactory Texas building, potentially exceeding 4,000 feet, while spanning somewhat narrower in width. Combined with the broader North Campus expansion adding more than 5.2 million square feet of new industrial space, the Optimus plant represents the largest addition to Tesla's manufacturing footprint since the Austin factory itself opened in 2022.

Why This Factory Matters

Tesla's stated production target for Optimus is staggering: up to 10 million units per year once the facility reaches full operational capacity — roughly 27,000 robots per day. To put that number in context, Tesla produced approximately 1.8 million electric vehicles in 2024. Optimus at scale would make Tesla the largest manufacturer of humanoid robots by an enormous margin.

Elon Musk has repeatedly described Optimus as potentially Tesla's most valuable product — more significant in the long run than even the vehicle business. The thesis is that general-purpose humanoid robots capable of performing physical labor across factories, warehouses, and eventually homes represent a market measured not in billions but in tens of trillions of dollars.

The phase-out of Model S and Model X production earlier this year, freeing up manufacturing space in Fremont, California, was the first step in this pivot. Initial Optimus production at Fremont is expected to begin in July or August 2026, with early units supporting internal Tesla factory tasks while the engineering team refines performance and autonomy. The Giga Texas facility will house a second-generation, high-volume production line targeting mass output starting in Summer 2027.

Built Alongside Terafab

The Optimus factory sits adjacent to the Terafab chip manufacturing facility, also under development at Giga Texas as part of Tesla's joint project with SpaceX and xAI. Terafab is designed to produce the advanced AI chips that will power Optimus's onboard neural networks, Tesla's Full Self-Driving system, and the broader AI infrastructure the Musk ecosystem depends on. Having chip fabrication and robot assembly within the same campus eliminates supply chain dependencies and gives Tesla direct control over two of the most critical inputs in its future product roadmap.

The co-location is deliberate. Tesla's vision for Optimus is not a robot that relies on cloud computing for every decision — it is a machine capable of real-time reasoning and physical dexterity using onboard silicon. That means the quality and availability of custom chips is directly tied to how fast Optimus can improve and scale.

Challenges Ahead

Tesla is candid that building this factory is only the beginning. Creating an entirely new manufacturing ecosystem for a product as complex as a humanoid robot — with precision actuators, sensors, custom motors, and AI-integrated control systems — requires solving supply chain problems that don't yet have standard solutions. Tesla is developing many of these components internally, a strategy that mirrors the vertical integration that made it the world's most efficient EV manufacturer but that demands significant upfront investment and time.

Still, the visible progress at Giga Texas this week is exactly the kind of concrete evidence that translates ambition into credibility. With steel rising and land clearing advancing, 2027 is looking increasingly like the year Tesla's robot story stops being a forecast and starts being a delivery.
