• Some Tesla executives had been told to prepare for the move .
• Advisers had discussed options including a spinoff, sale, or closure of the China operations .
• The report claimed Musk had designed Tesla's China business to be easily separable from the U.S. business because of geopolitical tensions .
• The rationale cited was that SpaceX's deep ties to U.S. national security and defense contracting made a combined entity with significant China exposure a potential regulatory and national security conflict .

Musk and Tesla China's Response

Elon Musk called the Wall Street Journal report "fake news" and "absurdly fake news", writing on X that the idea of selling Tesla's China business had "never even come up in a discussion ever" .

Tesla China separately denied the report as "false information" when contacted by local media outlets .

Despite Musk's flat denial, the report highlighted a very real strategic tension that has been simmering for years.

Why Tesla's China Business Is So Strategically Important

Tesla's China operations — anchored by the Shanghai Gigafactory — are central to the company's global output:

• Annual production capacity of more than 950,000 vehicles at the Shanghai plant .
• In 2025, the Shanghai factory accounted for more than half of Tesla's global vehicle deliveries — approximately 851,000 of 1.63 million units worldwide (about 52%) .
• The factory sources over 95% of its components locally from a dense supplier ecosystem in the Yangtze River Delta region .
• As of December 2025, the plant had produced its 4 millionth vehicle in just over six years of operation .
• The Shanghai factory also serves as a key global export hub, shipping vehicles to Europe, Asia-Pacific, and other markets .

Any separation would mean carving out Tesla's single biggest production site, its most important export hub, and its largest market outside the U.S. That's not a move any company would take lightly.

The Geopolitical and Regulatory Challenges of a Tesla-SpaceX Merger

Even if the WSJ report was wrong about immediate plans, the fundamental conflict it described is real. A merger between Tesla and SpaceX would face formidable hurdles, primarily because of SpaceX's role as a critical U.S. national security contractor.

CFIUS and national security reviews. Any merger combining a company with deep China operations (Tesla) and a company that holds classified U.S. defense contracts (SpaceX) would trigger a mandatory review by the Committee on Foreign Investment in the United States (CFIUS). Regulators would likely see Chinese exposure as an unacceptable channel for technology transfer or espionage risk .

SpaceX is a critical DoD contractor. SpaceX is a key provider for U.S. national security space launches, Starshield (the military version of Starlink), and other classified programs. U.S. Senators Elizabeth Warren and others have already raised concerns about Chinese investment in SpaceX, calling it "a critical Department of Defense contractor" and pressing the Pentagon on whether Chinese capital has accessed SpaceX shares through middlemen . In its S-1 filing, SpaceX stated it is "the primary launch provider for the U.S. government," having launched 11 out of 12 medium- and heavy-lift missions for the National Security Space Launch Program in 2025 .

Multi-jurisdictional regulatory approvals. JPMorgan analysts called this a "practical bottleneck," noting that securing approvals in both China and the U.S. simultaneously would be extremely difficult — China would likely oppose any restructuring that reduced Tesla's local commitment, while U.S. defense agencies would resist any foreign entanglement .

China's counter-leverage. China has its own review powers over foreign mergers that affect its national interests. Beijing would likely block or impose harsh conditions on any deal that saw a Musk-controlled combined entity divert investment or technology away from China .

Governance asymmetry. Musk controls roughly 85% of SpaceX's voting power but only about 20% of Tesla's, which would complicate any deal structure and raise questions about whether a merger would effectively be a SpaceX-led acquisition rather than a merger of equals .

Ongoing government scrutiny. As of early 2025, Elon Musk and his companies faced pending litigation, investigations, and enforcement actions across at least eight federal U.S. agencies, with potential liability exposure of over $2.37 billion, per a U.S. Senate investigation .

The Bottom Line

A Tesla-SpaceX merger would require navigating a near-impossible dual-track: satisfying U.S. national security clearances while managing China's regulatory sensitivities, with both governments holding effective veto power. The WSJ report may have been about contingency planning that Musk says never happened, but the strategic dilemma it described is a real and ongoing challenge for any company that operates at the intersection of U.S. defense contracting and Chinese manufacturing.
