Elon Musk has rejected reports that Tesla may separate or sell its Chinese operations, but the speculation has highlighted how difficult such a move would be even if the company wanted to pursue it.
The discussion began after The Wall Street Journal reported that a separation of Tesla’s China business had been considered in connection with a possible combination of Tesla and SpaceX. Such a merger could create national-security complications because SpaceX is a major US government and defence contractor, while Tesla operates two strategically important factories in China. Musk responded by calling the report “absurdly fake news,” and Tesla has not announced a divestment plan.
The underlying question remains important. Tesla is not merely selling imported cars to Chinese consumers. China is integrated into its manufacturing, supplier network, battery strategy, export operations, software development and energy-storage business. Decoupling would therefore involve far more than closing a regional sales office.
Shanghai Is Tesla’s Most Important Vehicle Factory
Tesla’s Shanghai Gigafactory began production in 2019 and has developed into the company’s most productive automotive plant. It manufactures the Model 3 and Model Y for Chinese customers while also supplying vehicles to Europe, Canada and markets across the Asia-Pacific region.
The factory has annual production capacity exceeding 950,000 vehicles and accounted for more than half of Tesla’s global vehicle deliveries during 2025. Removing it from Tesla’s direct control would create an enormous production gap that factories in the United States and Germany could not immediately replace.
Tesla itself explains in its 2025 annual report that international manufacturing allows it to reduce transportation expenses, lower production costs and limit exposure to unfavourable tariffs. Those advantages are especially important for mass-market vehicles such as the Model 3 and Model Y, where a relatively small cost increase can weaken competitiveness.
Building replacement capacity would take years and require billions of dollars. It would also be difficult to reproduce Shanghai’s manufacturing efficiency immediately. A new factory needs land, regulatory approval, equipment, trained employees, supplier capacity and a long production ramp before it can reliably produce vehicles at high volume.
China Provides More Than One-Fifth of Tesla’s Revenue
China is also one of Tesla’s largest sales markets. Tesla reported $20.96 billion in China-based revenue during 2025, representing approximately 22 percent of the company’s total annual revenue of $94.83 billion.
That contribution was larger than the revenue Tesla generated in any international market grouping outside China. The figures are based on the location where products were sold, meaning they reflect the commercial importance of Chinese customers rather than only the output of the Shanghai factory. The geographical breakdown appears in Tesla’s official SEC filing.
Tesla’s domestic position has weakened as Chinese manufacturers introduce newer vehicles at aggressive prices. Local brands controlled approximately 72 percent of China’s electric-vehicle market by mid-2026, while Tesla’s Chinese retail sales declined during the first half of the year. Companies including BYD, Xiaomi, Xpeng and Li Auto can update models rapidly and integrate batteries, software and consumer electronics features around local preferences.
However, competitive pressure does not make the market disposable. China remains the world’s largest and most advanced electric-vehicle market, giving Tesla access to customers, engineering talent and an unusually fast product-development environment. Leaving would remove a difficult competitor from the market, but it would also surrender one of the largest sources of future EV demand.
Tesla’s Chinese Supply Chain Is Deeply Localised
The strongest barrier may be the supplier network surrounding the Shanghai factory.
Tesla sources more than 95 percent of the components used in its China-made Model 3 and refreshed Model Y locally. It works with more than 400 Chinese suppliers, and over 60 of those companies also provide parts to Tesla operations outside China.
This means China is not an isolated production island that could be disconnected without affecting the wider company. Suppliers developed for Shanghai have become part of Tesla’s global manufacturing network.
Localisation lowers shipping expenses, shortens delivery times and allows engineers to resolve manufacturing problems quickly with nearby suppliers. Replacing hundreds of established relationships would require Tesla to qualify alternative factories, test components, renegotiate contracts and ensure that new parts meet automotive safety and durability requirements.
Tesla has already been reducing Chinese content in vehicles manufactured in the United States. Suppliers were reportedly asked to replace China-made parts for American vehicles over a one- to two-year period. That process shows that partial regional separation is possible, but it also demonstrates that decoupling must be gradual rather than immediate.
Battery Dependence Makes Separation Even Harder
Batteries are central to Tesla’s cost, production capacity and product performance. The company continues to depend on external manufacturers, including China’s Contemporary Amperex Technology Co. Limited.
CATL supplies lithium iron phosphate batteries used in vehicles produced at the Shanghai Gigafactory. Those vehicles are sold within China and exported to other markets, including Europe and Canada.
Tesla acknowledges that it has fully qualified only a limited number of battery-cell suppliers and has limited flexibility when changing between them. A disruption could restrict both vehicle and energy-storage production, while buying replacement cells elsewhere could increase costs. The risk is described directly in Tesla’s annual report.
Tesla is increasing battery and material production in Nevada and Texas, including lithium refining and lithium iron phosphate cell manufacturing. These investments may reduce strategic dependence over time, but the company has stated that battery-pack capacity remains a limitation on production growth.
Shanghai Is Also Becoming an Energy-Storage Hub
Tesla’s Chinese presence now extends beyond cars. Its Shanghai Megafactory produces Megapack battery-storage systems for utility, commercial and industrial customers.
The facility gives Tesla access to China’s extensive battery-material, cell and power-electronics ecosystem. Separating the Chinese business could therefore affect one of Tesla’s fastest-growing divisions at a time when electricity demand from renewable power and AI data centres is increasing.
Tesla lists both the Gigafactory and Megafactory as primary manufacturing facilities. It owns the buildings and holds land-use rights with initial 50-year terms, making any separation a substantial legal and asset transaction rather than a simple cancellation of a lease.
Tesla’s Chinese subsidiary also has access to a local working-capital facility backed by lenders in China. The facility was expanded during 2025, and Tesla disclosed commitments equivalent to tens of billions of yuan for production expenses and related financing needs. A sale or spin-off would require decisions about those loans, local assets, contracts and financial obligations.
Autonomous Driving Depends on Chinese Approval and Data
Tesla’s future strategy increasingly depends on software revenue, supervised Full Self-Driving and eventually autonomous transportation. China is both an important opportunity and a difficult regulatory environment for those ambitions.
Chinese rules restrict how vehicle and mapping data can be collected, transferred and processed. Tesla has consequently developed local data infrastructure and worked with Chinese partners to adapt its driver-assistance technology to local roads.
Shanghai previously allowed Tesla to pilot its advanced driving software, while the company pursued broader regulatory approval. China’s complex roads, dense cities and large Tesla fleet could generate valuable real-world driving experience, but the information cannot simply be treated like unrestricted US data.
An independent Chinese Tesla operation might make data separation easier from a national-security perspective. It could also make software development harder by dividing engineering systems, intellectual property, model updates and revenue between two businesses.
A Sale Would Need Support From Both Governments
Any separation would face scrutiny in Washington and Beijing.
US officials could examine Chinese supply-chain exposure, vehicle data and the consequences of combining Tesla with a defence-sensitive company such as SpaceX. Chinese authorities, meanwhile, would have influence over factory ownership, regulatory licences, data operations, land rights and any transfer to a new buyer.
Finding an acceptable purchaser would also be complicated. A Chinese buyer might concern US regulators and Tesla investors, while a non-Chinese buyer could face approval difficulties in Beijing. Closing the factories would destroy valuable production capacity and disrupt thousands of jobs and supplier contracts.
A spin-off may appear cleaner because Tesla shareholders could retain an economic interest in the Chinese company. Yet that structure would still require agreements covering technology, branding, software, batteries, exports and intellectual property.
Tesla Can Reduce Risk Without Leaving China
Complete decoupling is not the only strategy available. Tesla can continue separating data systems, regional suppliers and corporate structures while retaining its factories and Chinese sales operation.
It can source non-Chinese components for US vehicles, expand battery production in North America and limit sensitive technology transfers. At the same time, Shanghai can continue serving China and international markets where its cost advantages remain valuable.
This form of controlled separation is more realistic than an abrupt exit. It reduces the risk that one geopolitical dispute disrupts the entire company without forcing Tesla to abandon its most productive factory, hundreds of suppliers and one of its largest customer bases.
Tesla’s connection to China was built over years through investment, localisation and shared commercial interests. It helped the company lower prices, increase production and become a global manufacturer. Those same advantages have created dependencies that cannot be unwound quickly.
Musk may deny that a sale is being considered, but the broader dilemma remains. Tesla can make its American and Chinese operations more independent from each other. Fully removing China from Tesla or Tesla from China would be far more expensive, disruptive and strategically damaging.
