In short: Tesla’s China president Wang Hao has described the Shanghai Gigafactory as a “golden key” to mass-producing Optimus humanoid robots, the first time a Tesla executive has publicly linked the factory to robotics manufacturing. The plant delivered 851,000 EVs in 2025, and Tesla has deployed over 1,000 Gen 3 Optimus units across its own facilities, with production-scale manufacturing targeted from 2026-2028.

Tesla’s China president has described the Shanghai Gigafactory as a “golden key” to mass-producing Optimus humanoid robots, the first time a Tesla executive has publicly linked the company’s most productive car factory to its robotics ambitions.

Wang Hao, Tesla’s president in China, made the remarks in comments reported by the South China Morning Post and confirmed by the Washington Post and ABC News. He did not specify whether Tesla would repurpose existing Shanghai production lines or build new facilities for robot manufacturing, but the implication was clear: the factory that delivers more than half of Tesla’s global vehicle output is being considered for the next phase of the company’s hardware strategy.

Why Shanghai

The Shanghai Gigafactory delivered 851,000 electric vehicles in 2025, accounting for more than half of Tesla’s total global deliveries, and has now built more than four million cars since it opened. When Tesla ramped production of the new Model Y at the plant, it reached full output in six weeks. The supplier network, workforce density, and manufacturing infrastructure that made that speed possible are exactly the assets that humanoid robot production would require.

Wang’s argument is that Shanghai’s existing capabilities, its modular assembly lines, robotics infrastructure, and vertical integration, can be adapted for Optimus production without building from scratch. The factory is already planning to ramp six new production lines in 2026 across vehicles, robots, energy storage, and battery manufacturing.

For Tesla, producing Optimus in China would also mean access to a supply chain that increasingly dominates the components humanoid robots need: actuators, sensors, batteries, and precision motors. China now controls an estimated 90% of the global humanoid robot market, with domestic companies like Unitree and Agibot competing aggressively on both price and capability. Manufacturing Optimus in the same ecosystem would let Tesla leverage the cost advantages that have made its Shanghai-built vehicles the most profitable in its fleet.

Where Optimus stands

Tesla unveiled its Gen 3 Optimus, the first version designed for mass production rather than demonstration, in early 2026. More than 1,000 Gen 3 units have been deployed across Tesla’s own manufacturing facilities, primarily at Gigafactory Texas and the Fremont plant, where they perform factory tasks that serve as both real-world testing and workforce augmentation.

The production targets are ambitious by any standard. Tesla has discussed manufacturing a few hundred units in 2026, scaling to thousands and then tens of thousands annually by 2027 and 2028. Some internal targets cite one million units per year from Shanghai, though that figure has not been confirmed in any public filing. A dedicated robotics line at Gigafactory Texas is expected to reach higher volumes, with Elon Musk’s long-stated goal of pricing Optimus below $20,000 per unit.

The gap between deployed prototypes and mass production remains significant. Optimus can perform structured factory tasks, but the dexterous manipulation, autonomous navigation, and general-purpose capability that would make it useful outside Tesla’s own facilities are still in development. The robot’s hands, which Musk has identified as the critical hardware challenge, require the kind of fine motor control that no humanoid robot has yet demonstrated at production scale.

The China competition

Wang’s comments arrive at a moment when China’s humanoid robotics sector is advancing rapidly. Unitree’s G1 and H1 robots are already available for commercial purchase at price points well below what Tesla has indicated for Optimus. Agibot, backed by significant state and private capital, is developing robots aimed at factory and logistics applications. Fourier Intelligence, UBTECH, and a growing roster of Chinese startups are all targeting the same market.

The competitive dynamic creates both pressure and opportunity for Tesla. Manufacturing Optimus in Shanghai would put Tesla directly in the market where its competitors are strongest, but it would also give the company access to the talent pool, component suppliers, and government incentives that are accelerating Chinese robotics development. China’s central and local governments have identified humanoid robots as a strategic technology, with subsidies and policy support that other regions have been slower to match.

For European competitors like Germany’s Neura Robotics and other emerging players, Tesla’s potential Shanghai production adds another dimension to an already complex competitive landscape. The combination of Tesla’s brand, manufacturing scale, and AI capabilities with China’s supply chain advantages could prove difficult to counter.

The strategic calculation

The decision to produce humanoid robots in Shanghai, if it materialises, would carry geopolitical implications. Tesla’s China operations already navigate the tension between US and Chinese technology policies. Adding robotics production, a category that both governments consider strategically sensitive, would deepen Tesla’s dependence on Chinese manufacturing at a time when the political relationship between the two countries remains volatile.

Musk has historically used Tesla’s China presence as leverage, the Shanghai factory’s success gave Tesla the production capacity and cost structure that funded its global expansion. Applying the same playbook to Optimus would be consistent with that strategy: use China’s manufacturing ecosystem to achieve the cost and scale targets that make the product viable, then expand production globally once the economics are proven.

Whether the Shanghai Gigafactory actually becomes a humanoid robot production site remains to be seen. Wang’s comments signal intent rather than commitment, and the distance between a Tesla executive calling a factory a “golden key” and that factory producing robots at scale is measured in years of engineering, regulatory approvals, and capital expenditure. But the fact that Tesla is publicly discussing the possibility suggests that Optimus production planning is further along than the company’s carefully staged public demonstrations have indicated.

Tesla’s Shanghai factory has already proved that it can manufacture complex hardware faster and cheaper than anyone expected. The question is whether that capability can translate from electric vehicles to autonomous machines that walk, grasp, and navigate the physical world. If it can, Wang’s “golden key” metaphor may prove less promotional than prophetic.
