Major Structural Obstacles to a Merger
The market remains highly skeptical of a merger announcement in 2026. The main structural obstacles are as follows:
Regulatory review: Any major merger would need to undergo antitrust and national security reviews
SpaceX's status as a defense contractor: SpaceX is a major U.S. defense contractor, making a merger with a company that has deep ties to China politically sensitive
Tesla's significant operations in China: China is Tesla's second-largest market, with wholesale sales reaching 93,579 vehicles in July
Shareholder preference for pure-play companies: The market generally favors companies focused on a single business and tends to avoid conglomerate valuation discounts
Valuation mismatch: Integrating a profitable automotive business with capital-intensive aerospace and AI businesses would pose significant challenges
Board approval and formal procedures: Elon Musk emphasized that M&A matters cannot be discussed hastily
SpaceX Stock Falls After Q2 Earnings
SpaceX's first public earnings report following its June 2026 IPO, covering the second quarter of 2026, showed revenue of $7.8 billion, up 92% year over year, and a narrowing net loss; overall performance appeared solid. However, capital expenditures exceeded $18 billion during the quarter, primarily for AI infrastructure, and the stock fell approximately 8% to 11% as the market absorbed the massive spending plans and the approaching expiration of the lock-up period.
This earnings backdrop helps explain some of the market's cautious sentiment regarding the timing of a merger.
Elon Musk Denies Rumors of Tesla Divesting Its Chinese Operations
The Wall Street Journal reported that Tesla had internally discussed spinning off, selling, or otherwise restructuring its Shanghai operations. The geopolitical rationale was that, as a defense contractor, SpaceX's merger with a company deeply tied to China would be politically sensitive. Elon Musk strongly denied the report, calling it “absurd fake news” and claiming that the matter had never been discussed internally. China is Tesla's second-largest market, with wholesale sales reaching 93,579 vehicles in July.
