Tesla starts building Optimus robots on its Fremont production lines, but won't say how many
Tesla's third-quarter update says the humanoid robots now coming off its California lines are the first 'production-quality' Optimus units. It gave no production rate, price or date for outside sales.

Key points
- Announced in Tesla's Q3 2026 update on October 21
- Optimus production began on high-volume lines in Fremont, California, where Model S and X were built
- Tesla says the current process is 'suitable for a commercial product'
- No production rate, unit count, price or customer sales date was given; a Texas factory is under construction
Tesla says its humanoid robot has crossed an important line. In its third-quarter 2026 update, posted October 21, the company wrote:
"Optimus production began in Fremont on our high-volume lines. The bots coming off this line are the first production-quality bots that we have manufactured."
What Tesla announced
Tesla went further than saying the robots are being built. It also said:
"While we will continue to iterate on the hardware and manufacturing process, we have proven that the current manufacturing process for Optimus is suitable for a commercial product."
In the update's factory table, Optimus now has two rows:
| Location | Status |
|---|---|
| Fremont, California | Early ramp |
| Giga Texas | Construction |
What Tesla didn't say
The update leaves the most important questions open, as Tesla North points out. Tesla gave:
- no production rate,
- no unit count,
- no price,
- no date for selling Optimus to outside customers,
- no word on which version of the robot is being built.
Unlike the car and Megapack battery rows in the same table, the Optimus rows have no capacity numbers.

How we got here
The Fremont line has been in the works all year:
- January: Elon Musk said the Model S and Model X would be discontinued to free floor space for Optimus, with a long-term goal of one million robots a year in California.
- April: Musk said the initial ramp would be "quite slow," partly because the robot needs about 10,000 parts.
- Late March: construction began on a dedicated Optimus factory at Giga Texas.
- Second quarter: Tesla decommissioned the S and X lines; early robots went to collecting training data in what it calls the "Optimus Academy."
Why it matters
Humanoid robots are one of the most hyped corners of AI, and Musk has said Optimus and Cybercab will be the vast majority of Tesla's value. "Production-quality" is a meaningful step, but until Tesla shares numbers, there's no way to tell whether it's building hundreds of robots or a handful. Watch the next quarterly update for the first hard figures.
