Giga Texas Optimus Factory: 5 Details That Matter

A new timelapse from aerial observer Joe Tegtmeyer puts five months of Giga Texas Optimus factory construction into sharp focus — and the pace is striking. From bare ground in late March 2026 to a rising multi-story steel superstructure today, the footage compresses what's become one of the most ambitious manufacturing buildouts in Tesla's history into a single watchable sequence. Here are the five numbers and milestones that define where this project stands.

1. Construction Began March 23, 2026 — Five Months In

Ground broke on the Optimus factory site at Giga Texas's North Campus on March 23, 2026. Tegtmeyer's timelapse captures each week from that starting point to today, making the rate of progress easy to gauge. What was a cleared site in late March is now a recognizable industrial structure. Five months is a short window for a building of this scale, which makes the visual transformation in the video genuinely notable rather than routine construction footage.

2. The Structure Is Approximately 25% Complete

As of mid-August 2026, the steel superstructure was estimated to be roughly 25% complete. That figure comes with important context: floor decking installation was already underway by mid-June, meaning the build isn't just going vertical — horizontal work is progressing in parallel. Seven large cranes were active on site by June 17, a level of equipment density that signals Tesla is not treating this as a phased, conservative rollout. The North Campus area is described as a continuous hub of steel assembly activity.

3. The Planned Footprint Is 5.2 Million Square Feet

The Giga Texas Optimus factory is planned at 5.2 million square feet of new construction, with that full footprint targeted for completion by the end of 2026. For reference, that's a substantial addition to an already large campus. GeoPier ground reinforcement work and additional footing construction visible across the site suggest the building's eventual boundaries extend well beyond what's currently framed in steel. An on-site steel corrugated pipe manufacturing plant has even been established nearby specifically to supply materials for the project's rainwater management infrastructure — a detail that underscores how self-contained this buildout has become.

4. Volume Production Is Targeted for Summer 2027

The first Optimus production lines at Giga Texas are anticipated to come online in 2027, with volume production specifically targeted for Summer 2027. This facility is expected to produce the Gen 4 variant of Optimus — the higher-volume model — rather than the Gen 3 currently being manufactured at Fremont. For context, Fremont's mass production of Gen 3 began January 21, 2026, and current output there is expected to reach 50,000–100,000 units in 2026, primarily for training data collection rather than productive deployment. Giga Texas is where the real volume story begins.

5. The Long-Term Target Is 10 Million Units Per Year

Tesla's stated ambition for Giga Texas is to build a dedicated Optimus manufacturing facility capable of producing 10 million units annually at full scale — roughly 27,000 robots per day. That number is a long-horizon target, not a near-term commitment, and the gap between today's 25%-complete structure and that production ceiling is enormous. But the construction pace documented in Tegtmeyer's timelapse suggests Tesla is building infrastructure that takes the target seriously. The $20 billion capital investment Tesla has allocated for 2026 covers Optimus manufacturing infrastructure at both Fremont and Giga Texas, which gives some sense of the financial commitment behind the footage.

The timelapse is worth watching in full — five months of construction compressed into a short clip makes the trajectory clearer than any single progress photo. The Summer 2027 production target is now less than a year away, and the steel going up in Austin will need to be enclosed, equipped, and staffed before that clock runs out.
