Retail flows across Asia remained heavily concentrated in newly listed, high-beta names, most notably Chinese robotics maker Unitree following its blockbuster Shanghai debut. The retail craze surrounding physical AI merely shows Beijing’s accelerating push to dominate the humanoid market.
To close out the week, we pivot across the Pacific for a peek inside the US humanoid-robotics supply chain, where Tesla’s Fremont buildout provides a timely indicator of how quickly physical AI is advancing.
Rajat Gupta, a JPMorgan analyst who covers Tesla, recently toured Tesla’s Fremont factory and reported to clients this week that the facility, once the birthplace of the company’s electric vehicles, is now pivoting toward producing robotaxis and humanoid robots.
Gupta and his colleagues toured the roughly 5-million-square-foot facility and found that the discontinued Model S and Model X production lines are being replaced by manufacturing equipment for Tesla’s Optimus humanoid.
"On Optimus, production lines are being installed at Fremont (the area was tarped off at the time of our visit), and TSLA remains largely on schedule for the targeted four-month transition following the end of S/X production in May, with initial humanoid deployments in 2H26 expected to focus on Optimus Academy for training and data collection, followed by internal factory use and external sales as early as 2H27," the analyst said.
He said that Optimus robots are not currently working inside the Fremont plant. Initial deployments in the second half of 2026 will instead take place at the "Optimus Academy," where the robots will collect real-world training data before being deployed in factories.
"Overall, we came away from the factory tour with greater conviction in the robotaxi fleet ramp through late 2026 and early 2027, as well as an Optimus SoP that remains largely aligned with previously communicated timelines, both of which are central to the long-term thesis, while near-term commentary on demand drivers and FSD uptake remains constructive," the analyst said.
Here are Gupta’s top takeaways from walking the Fremont factory floor:
Facility details. TSLA’s Fremont facility serves as the company’s primary test bed for innovation, supporting the launch of both new vehicles and humanoids across its expansive roughly 5-million-square-foot footprint. The plant manufactures premium Model Y variants and performance and premium Model 3 variants, while the recently decommissioned S/X lines, retired in early May, are being replaced by Optimus production lines. The factory showcases the breadth of TSLA’s automation capabilities, featuring numerous custom-built robots and proprietary software designed to enhance manufacturing speed and precision. Production continues under several modernized tents, originally erected during the Model 3 "production hell" days, which remain integral to the facility’s operations. During our visit, we observed gigapress machines, stamping operations and general assembly lines and participated in FSD demonstrations involving the Model Y L variant and the Cybertruck.
Giga casting and stamping. TSLA’s innovative giga-casting process, first introduced with the Model Y, consolidates 70 underbody components that would otherwise require welding, significantly streamlining production. This approach reduces the number of robots needed on the welding line. The Model Y utilizes roughly 300 robots, compared with approximately 1,000 for the Model 3. TSLA also attributes this advancement to its materials-science expertise, including the development of a custom aluminum alloy, a capability enhanced through its collaboration with SpaceX. For stamping, TSLA employs Schuler presses with six progressive, interchangeable dies. TSLA stamps roughly 10 visible vehicle components in-house, while hundreds of remaining stamped parts are sourced from suppliers.
Unboxed manufacturing. TSLA emphasized that Cybercab production leverages an unboxed manufacturing process in which large subassemblies are built independently and in parallel, then joined together during the final stage. This approach allows open access from all angles, enabling simultaneous installation and streamlining the overall assembly process.
FSD demos. We participated in FSD demonstrations involving the Model Y L and Cybertruck, with the team walking us through the various modes, ranging from Sloth to Mad Max. The vehicles demonstrated notable driving accuracy, including navigating through a construction zone without manual intervention. The Autopark function worked seamlessly as well.
