Tesla’s humanoid robots are no longer prototypes shown on a stage — they’re now rolling off a real production line in California. The company announced on October 21, 2026 that it has begun building production-quality Optimus robots at its factory in Fremont, marking the most serious step yet in Elon Musk’s plan to turn Tesla from a carmaker into a robotics company.
The announcement came as part of Tesla’s third-quarter earnings update, alongside a sobering financial result: the company’s profit fell 43% while revenue stayed flat.
A robot factory where luxury cars used to be made
The new Optimus line occupies manufacturing space at Tesla’s Fremont factory that once built the company’s premium electric vehicles. Earlier this summer, Tesla dismantled the Model S and Model X assembly lines — a job completed in just 46 days — to make room for robot production equipment.
In its third-quarter letter to shareholders, Tesla wrote that “the bots coming off this line are the first production-quality bots that we have manufactured,” adding that the company has demonstrated the manufacturing process is “suitable for a commercial product.”
Musk was quick to temper expectations on the earnings call, calling it “early production” and warning that the ramp-up would be slow and “somewhat bumpy because it is such a radically new product.”
What “production-quality” actually means right now
Despite the milestone, the first Optimus units are far from a finished consumer product. Musk admitted there is still significant work ahead on the robot’s design, reliability, and durability.
“There’s still some things we need to tweak about the design, because you need to deliver a robot that is safe and reliable and has long duration, so it can’t, like, wear out after a month,” Musk said. “And there’s still quite a lot of work to do with regard to the AI and the robot for it to be truly useful for open-ended tasks.”
The company has also been wrestling with practical hurdles, including difficulties perfecting the robot’s hands and restrictions on Chinese rare-earth magnets used in its components.
The 20,000-a-week target — and the road to get there
Musk nonetheless laid out an aggressive production roadmap. He said “the vast majority” of the equipment for a line capable of building one million robots per year has already arrived in Fremont, with an even larger line planned for Tesla’s Giga Texas facility.
“I would expect that it takes us probably at least a year, maybe a little longer, to get to that annualized rate — to get to 20,000 units a week,” Musk said, noting that roughly 10,000 things have to go right along the way.
Current production uses the Optimus Gen 3 design, with a Gen 4 version planned for when the Texas capacity comes online. Tesla also plans to integrate its next-generation AI5 chip into Optimus around April 2027, a chip Musk says brings far more computing power than the current AI4 hardware.
External customers — other companies buying Optimus — will have to wait. Musk expects the remaining AI, design, and durability issues to be resolved around the end of 2027, which is when Tesla plans to begin supplying robots to outside companies. Early uses, he said, will be industrial: dangerous, repetitive, around-the-clock tasks. Consumer robots would come later as volume scales.
“I remain convinced that Optimus will be the biggest product on Earth,” Musk said.
The other side of the story: profit plunges 43%
The robot milestone arrived alongside weak financials. Tesla reported third-quarter revenue of about $28.05 billion — essentially flat year over year — while GAAP net income dropped 43% to $787 million from $1.37 billion a year earlier.
The squeeze came from heavy spending on AI, autonomous driving, and Optimus development, which pushed operating expenses up sharply, plus lower sales of regulatory credits that have historically padded Tesla’s profits.
Tesla delivered 486,532 vehicles in the quarter — slightly more than the previous quarter, but fewer than in the same period last year. The company did note that demand is being driven increasingly by its Full Self-Driving offering, with the Cybercab fleet in Austin growing significantly.
Why this matters
The humanoid robot race is heating up fast, and right now the leaders aren’t in California. According to Counterpoint Research, Chinese manufacturers — led by AGIBOT, Unitree and three other firms — captured 86% of the more than 22,000 humanoid robots shipped in the first half of 2026, though most of those went to entertainment, research, and performances rather than factory work.
Tesla is betting that it can do what it did with electric cars: scale manufacturing until costs collapse. Musk is aiming for a long-term Optimus price of around $20,000, down from the estimated $50,000–$60,000 it currently costs to build one at low volumes.
Whether Optimus becomes the “biggest product on Earth” or another overpromised Musk timeline will depend on one thing the spreadsheets can’t show: whether the robots actually work. For the first time, Tesla has a real production line to find out.
