Elon Musk didn't deny the possibility of combining Tesla and SpaceX during Tesla's July 22 earnings call, signaling that a merger between the two companies remains a live possibility despite significant obstacles. When an analyst asked whether Musk sees eventual synergies between Tesla and SpaceX, which went public in June, he acknowledged "more and more overlap" between the two companies but stopped short of committing to any deal.

What Did Musk Actually Say About a Potential Merger?

Musk pointed specifically to Terafab, SpaceX's planned chipmaking venture, as evidence of deepening connections between the companies. He described it as "really going to be a gigantic project." When pressed on whether a merger could happen, Musk said he couldn't discuss "combining companies and that kind of thing" in a public earnings setting, adding that any such move would have to happen through "the appropriate process". That careful non-denial has caught the attention of investors and Wall Street analysts alike.

The two companies are already deeply intertwined today. Tesla's general counsel noted on the earnings call that the relationship deepened this year through an investment and a framework agreement. Grok, the artificial intelligence (AI) assistant built into Tesla vehicles, actually comes from the xAI business that SpaceX absorbed before its initial public offering (IPO). Tesla's Cybercab robotaxis are expected to rely on SpaceX's Starlink network for connectivity, and Terafab could eventually supply the chips Tesla needs for its cars and robots.

Why Would a Tesla-SpaceX Merger Make Sense?

JPMorgan told clients this month that a combination would make strategic sense on paper, uniting Musk's ambitions in AI, transportation, and space under one roof. The logic is straightforward: combining the companies could streamline operations, reduce redundancy, and create synergies across multiple business lines. However, the investment bank also cautioned that executing a deal is far messier than the logic suggests.

Two major obstacles stand out. The first is pricing. A merger requires an exchange ratio, which determines how many shares of one company each share of the other is worth. Both stocks trade heavily on future potential rather than current profits. SpaceX carries a market value of approximately $1.5 trillion on trailing-12-month revenue of about $19 billion, up 33 percent from the year before, and it remains unprofitable. Tesla, valued at about $1.2 trillion, trades at more than 300 times earnings after this week's post-earnings sell-off.

What Are the Major Obstacles to a Deal?

Beyond valuation challenges, several structural and regulatory complications could derail or significantly delay any merger:

• Musk's Conflicting Interests: Musk controls about 85 percent of SpaceX's voting power but only about 20 percent of Tesla's, meaning he effectively sits on both sides of any negotiation. Tesla's board would need an independent process robust enough to survive shareholder lawsuits that reliably follow deals of this magnitude.
• National Security Concerns: SpaceX is a major defense and government contractor, while Tesla operates one of its largest factories in Shanghai and depends on China for a meaningful share of its sales and supply chain. Folding a national security asset into a company with deep Chinese exposure invites regulatory scrutiny in both countries.
• International Complications: Starlink isn't even approved to operate in China, adding another layer of complexity. A regulatory review could stretch on for years with no guarantee of approval.

The pricing problem cuts both ways. SpaceX shareholders own the larger company by market value and the asset Musk has the deeper economic interest in. Tesla shareholders would gain exposure to Starlink's fast-growing revenue in a deal, but they'd be paying with stock that the ultimate decision maker has less personal incentive to defend. Every version of the math involves the same person on both sides of the table.

Investment analysts suggest that investors shouldn't own either stock based on speculation about a potential merger. While Musk's comments suggest the idea is at least alive, the timing and terms remain unknowable today, and the regulatory path could take years to resolve. Both companies already price in spectacular futures, and each business should have to prove its own case independently first.
