Tesla's Optimus Factory at Giga Texas Raises Its First Steel Structure
5 min read read
Drone footage captured by Giga Texas construction observer Joe Tegtmeyer on May 27, 2026 documented the first steel structure rising at Tesla's dedicated Optimus humanoid robot factory on the North Campus of Gigafactory Texas. The milestone — from ground clearing to structural steel — took roughly six months, a compressed construction timeline that tracks with Tesla's stated urgency around the Optimus program. Foundation equipment moved in during April 2026; a month later, the first beams are up.
The North Campus facility is designed to be enormous. Tesla's construction permits describe a project that will add more than 5.2 million square feet of industrial space — a footprint approaching the same length as the main Giga Texas building itself, which stretches nearly 4,000 feet. The eventual production target, per Elon Musk's statements, is 10 million Optimus units per year, roughly 27,000 per day at full capacity. That figure remains a long-term goal, not a near-term plan, but the physical infrastructure being built is scaled to accommodate it.
Timeline: From Clearing to Steel in Six Months
The construction pace at the North Campus tells a relatively straightforward story of a project moving fast within the constraints of industrial building. Ground clearing at the site was first confirmed in drone footage from November 2025. That phase — removing vegetation, grading, and preparing soil — ran through the end of 2025 into early 2026.
Geopier foundation equipment, used for ground improvement and deep foundation preparation, appeared at the site in April 2026. That equipment signals the transition from site clearing to actual structural preparation, and it typically precedes steel erection by weeks rather than months. On the May 27 footage, the first structural steel is visible — confirming the site has crossed from groundwork to vertical construction.
| Phase | Date | Status |
|---|---|---|
| Ground clearing begins | November 2025 | Completed |
| Foundation equipment on site | April 2026 | Completed |
| First steel structure erected | May 27, 2026 | Confirmed |
| Major structural work complete | Late 2026 | Projected |
| Second-gen production line active | Summer 2027 | Planned |
Fremont Comes First, Then Texas
The Giga Texas North Campus is not where Optimus production begins. Tesla's initial manufacturing ramp for the robot is slated for the Fremont, California factory, with low-volume output targeted for July or August 2026. Fremont was converted from Model S and Model X production, which Tesla wound down earlier this year, freeing up factory space for the robot program.
The Texas facility represents the second wave — a purpose-built, ground-up factory optimized for the Optimus V4 platform at a scale that Fremont's repurposed floor space cannot match. Tesla has described the Giga Texas production line as a second-generation setup, designed from the start around the specific manufacturing requirements of a humanoid robot rather than adapted from automotive tooling.
"This will allow this new factory to grow to nearly the same length as the main Giga Texas factory." — Joe Tegtmeyer, Giga Texas construction observer, May 27, 2026
The Economic Logic Behind the Scale
Tesla's target for Optimus involves numbers that have no precedent in the robotics industry. No company has come close to building humanoid robots at automotive production scale. Boston Dynamics, which has been selling its Atlas platform commercially, measures output in the hundreds per year. The implied math for Tesla's 10 million unit target — if taken seriously — would require manufacturing and supply chain infrastructure that doesn't currently exist anywhere.
Musk has framed the business case in explicit financial terms: Optimus, if it delivers on what he's described, could generate revenue that exceeds Tesla's entire vehicle business. A humanoid robot capable of performing physical labor in industrial settings — which is where Tesla is initially targeting deployment, including its own factories — at a cost below human labor wages represents a different category of economic opportunity than anything in Tesla's current product portfolio.
The investment figures being discussed reflect that scale. Estimates for the Giga Texas North Campus construction range from $5 billion to $10 billion over the full build-out, with Tesla's overall capex guidance for 2026 set at more than $25 billion — up from the prior $20 billion guidance provided earlier in the year.
The Bottom Line for Optimus Watchers
The first steel structure at the Giga Texas North Campus is a construction milestone, not a product milestone — and it's worth being clear about the difference. The building being erected will eventually house production lines; those lines will eventually make robots; the robots will eventually need to demonstrate the capabilities that justify the investment. None of that has happened yet at this facility.
What has happened is that Tesla has moved from permits and ground clearing to vertical construction in roughly six months, and the scale of what's being built is consistent with the long-term targets Musk has stated publicly. Fremont's low-volume ramp later this summer will be the first real signal of whether the manufacturing and software side of Optimus is tracking to plan. Texas is what happens if it does.
