Elon Musk has strategically structured Tesla's China business to be easily separable from its U.S. operations, according to a report by the Wall Street Journal. The design aims to mitigate risks tied to escalating U.S.–China geopolitical tensions and could also pave the way for a potential merger between Tesla and SpaceX.

Discussions among advisers about a possible combination of the two companies have explored several options, including a spinoff or sale of Tesla's China unit, as a means to navigate anticipated regulatory hurdles. The Shanghai Gigafactory—Tesla's most important manufacturing base outside the United States—occupies a central role in any such restructuring plan.

SpaceX's status as a major U.S. defense and national security contractor adds a layer of complexity to any merger scenario. A deal uniting Tesla, a publicly traded electric-vehicle manufacturer, with SpaceX, a privately held aerospace company, would likely draw intense scrutiny from regulators in both Washington and Beijing. In the United States, the Committee on Foreign Investment in the U.S. (CFIUS) reviews transactions involving foreign interests that could affect national security, while China's State Administration for Market Regulation (SAMR) oversees antitrust reviews of significant corporate combinations.

Tesla has operated the Shanghai Gigafactory since 2019, when it became the company's first fully owned auto plant outside the United States. The facility has been a cornerstone of Tesla's global production capacity and its largest export hub, making its governance and ownership structure a critical factor in any corporate reorganization. The plant's strategic importance has grown as Chinese automakers such as BYD have intensified competition in the world's largest EV market.

Musk has previously expressed interest in combining Tesla and SpaceX, noting potential synergies in areas such as energy storage, materials science, and artificial intelligence. However, he has also acknowledged that the two companies' differing ownership structures and regulatory profiles present significant obstacles. SpaceX was valued at approximately $180 billion in a secondary share tender in late 2023, while Tesla has at times ranked among the world's most valuable publicly traded companies by market capitalization, underscoring the scale and unprecedented nature of any potential combination.

Data from prediction markets referenced in the CryptoBriefing report indicates growing expectations of a possible merger announcement. The implied probability of a Tesla–SpaceX merger being announced by December 31 has reportedly risen to 29.5%, reflecting heightened market interest in a potential year-end development.

Regulatory scrutiny from both the United States and China will be pivotal, as any transaction involving SpaceX—given its defense contracts with the U.S. government—would likely face rigorous national security reviews. Observers are closely watching for official statements from Tesla or SpaceX regarding any consolidation plans.
