In summary, Tesla’s China president Wang Hao has called the Shanghai Gigafactory a “golden key” for mass-producing Optimus humanoid robots, marking the first time a Tesla executive has linked the factory to robotics production. In 2025, the plant delivered 851,000 EVs, and Tesla has deployed over 1,000 Gen 3 Optimus units within its facilities, with mass production aimed for 2026-2028.
Wang’s statement, reported by the South China Morning Post and confirmed by other outlets, highlights the Shanghai Gigafactory’s potential role in Tesla’s robotics strategy. While he didn’t specify if existing production lines would be repurposed or if new facilities would be built, the implication was that this key plant is being considered for a new phase in Tesla’s hardware strategy.
The Shanghai Gigafactory, which delivered 851,000 electric vehicles in 2025, makes up more than half of Tesla’s global deliveries and has produced over four million cars since opening. The plant’s rapid production of the new Model Y shows the supplier network, workforce density, and manufacturing infrastructure crucial for producing humanoid robots. Wang argues that Shanghai’s capabilities, like modular assembly lines and robotics infrastructure, are adaptable for Optimus production without starting from scratch. Six new production lines for vehicles, robots, energy storage, and battery manufacturing are planned for 2026.
Producing Optimus in China also provides access to a supply chain dominating necessary components like actuators and sensors. With China controlling about 90% of the global humanoid robot market, making Optimus in this ecosystem means Tesla can leverage cost advantages similar to its Shanghai-built vehicles.
Tesla introduced the Gen 3 Optimus, the first version designed for mass production, in early 2026, deploying over 1,000 Gen 3 units at Gigafactory Texas and Fremont, where they perform tasks for real-world testing and workforce augmentation. Production aims are ambitious, with plans to manufacture hundreds in 2026, scaling to thousands and tens of thousands by 2027 and 2028. Some internal goals suggest one million units per year from Shanghai, though not publicly confirmed. A dedicated line in Gigafactory Texas aims for higher volumes, with a goal to price Optimus under $20,000 per unit.
Despite this progress, significant gaps remain between prototypes and mass production. Optimus can handle structured tasks, but the dexterity, autonomous navigation, and general-purpose features needed for wider usefulness are still developing. The robot’s hands, crucial to success, lack the fine motor control seen in mass-produced humanoids.
Wang’s remarks come as China’s humanoid robotics sector advances rapidly. Unitree and Agibot offer robots below Tesla’s indicated price for Optimus. Manufacturing Optimus in Shanghai positions Tesla in a market where competitors are strong and grants access to talent, suppliers, and government incentives boosting Chinese robotics growth. While China considers humanoid robots a strategic technology, offering policy support, other regions are slower to match.
Tesla’s potential Shanghai production poses a challenge for European competitors like Germany’s Neura Robotics. Combining Tesla’s brand, scale, and AI with China’s supply advantages could be tough to counter.
If Tesla decides to produce robots in Shanghai, it would have geopolitical implications, deepening Tesla’s reliance on Chinese manufacturing amidst volatile US-China relations. Historically, Tesla has leveraged its presence in China; the success of the Shanghai factory supported global expansion. Using this approach for Optimus aligns with existing strategies by using China’s ecosystem to achieve cost and scale goals before global expansion.
While it’s uncertain if the Shanghai Gigafactory will produce humanoid robots, Wang’s comments suggest planning is more advanced than public demonstrations indicate. Tesla has shown it can produce complex hardware quickly and affordably. Whether these capabilities extend to autonomous robots remains to be seen, but Wang’s metaphor of a “golden key” might become more than just promotional.
