Tesla's Optimus costs $46,000 with China. Without China, it's $131,000
Elon Musk originally wanted to sell Tesla's Optimus humanoid robot for around $20,000. That price depends almost entirely on a supply chain Musk did not build, located in a country that U.S. policy is increasingly treating as an adversary.
As reported by Interesting Engineering and the South China Morning Post, the current Optimus unit cost with Chinese components is approximately $46,000. Remove those components and build the same robot entirely outside of China, and Morgan Stanley puts the number at $131,000.
That's a nearly 3X gap between Musk's target retail price and the non-China manufacturing cost.
Tesla has been engaging hundreds of Chinese component suppliers for Optimus for roughly three years. The parts they make — actuators, motors, reducers, vision systems — are now being called the "Optimus chain" by suppliers, a deliberate echo of the iPhone supply chain that Apple spent decades building in China.
The structure of the dependency
The current arrangement is: core components manufactured in China, final assembly in the U.S. Tesla China President Allan Wang Ho has called GigaShanghai a "golden key" to mass-producing Optimus at scale. Musk himself, referring to the Shanghai factory, has called it "a gem" and praised China's "very strong, inherent ability to do manufacturing well."
This mirrors what Tesla did with electric vehicles, at least in China.
Chinese manufacturing partners, Chinese battery supply chains, Chinese production capacity ... then export the vehicles globally. The EV strategy worked. The robotics strategy looks like it is being built on the same template.
The numbers behind the Chinese manufacturing advantage are not subtle. Chinese companies shipped approximately 90% of the roughly 13,000 humanoid robots delivered worldwide in 2025. The country has built up supplier ecosystems for harmonic drives, frameless motors, and high-torque actuators that simply don't exist at comparable cost or scale elsewhere. Unitree's G1 humanoid robot sells for $16,000. That price is possible because Unitree sources and manufactures in China.
Tesla cannot get to $20,000 without the same supply base.
The geopolitical math
But politically, this is getting more and more complicated.
The U.S. government is actively restricting Chinese technology in semiconductors, AI chips, and drone components. Humanoid robotics is increasingly considered strategically sensitive by both governments. The Biden and Trump administrations both tightened export controls on advanced manufacturing technology. A $780 billion humanoid component market projected by Morgan Stanley by 2040 will not go unnoticed by Washington policymakers.
The framing being applied by analysts is "U.S. brain, Chinese body." American companies lead in AI and software; Chinese companies dominate the physical hardware manufacturing.
Tesla's Optimus is the clearest example of this split. The intelligence is in Palo Alto and Austin. The arms and legs are made in Guangdong and Zhejiang.
That arrangement is cost-optimal today. Whether it remains politically viable over the next five to ten years is a different question entirely.
The Optimus production ramp at Fremont — where Tesla is repurposing Model S and X lines — assumes a component supply chain that runs through Chinese factories. Disrupting that supply chain, through tariffs, export controls, or political decisions by either government, doesn't just raise costs. It delays production timelines by years, because no equivalent non-Chinese supply base exists at scale.
The competitive pressure
BYD confirmed its first humanoid robot would debut in August 2026. Unitree is already in the market at $16,000 and up. DEEP Robotics, AgiBit, Fourier Intelligence, and over 100 other companies ... the Chinese humanoid robot ecosystem is broad, vertically integrated, and moving fast.
These companies do not face a China-dependency risk. They are the supply chain.
Tesla is trying to build a global humanoid robot business on top of Chinese manufacturing, while simultaneously being a U.S. company subject to U.S. export control regimes, in an industry that both governments consider strategically important.
That's a hard position to hold long-term.
But Musk has played this game before. He knows the supply chain is a dependency. The question is whether he has a plan to reduce it, or whether he's betting that U.S.-China manufacturing ties in robotics will remain stable long enough to get Optimus to mass market before the politics catch up.
