SpaceX-Tesla merger could hurt Tesla shareholders

Investor Anthony Pompliano on Monday urged Elon Musk to merge Tesla with SpaceX, putting Tesla stock in focus as investors weighed the proposal. Tesla shares are down more than 6% since the start of 2026.

Tesla is a publicly traded auto and energy company that investors expect to generate steady free cash flow. SpaceX reported a $4.28 billion net loss in the first quarter, largely tied to hardware research and development for Starship and the expansion of the Starlink satellite network. SpaceX’s programs require continuous large-scale capital.

Under a proposed merger, Tesla shareholders might exchange TSLA shares for shares in a combined company, changing the profit profile investors hold. The combined entity would add exposure to large R&D losses and projects without guaranteed near-term returns.

Market analysts note that diversified groups with unrelated operations often receive lower valuation multiples than focused companies. A lower multiple on a combined Tesla–SpaceX firm would affect the market value of shares held by current Tesla investors.

Governance differences are also central. SpaceX uses a dual-class voting structure that gives founders outsized control, and Elon Musk is estimated to hold about 85% of SpaceX voting power. A merger that retains or extends that structure would alter voting rights for existing Tesla shareholders and could conflict with governance policies used by major institutional investors.

Regulatory and national security review would follow a combination of the companies. Tesla’s manufacturing and supply chain are closely tied to China, with Gigafactory Shanghai a major contributor to global output. SpaceX operates under U.S. national security rules as a contractor for NASA and the Department of Defense. Combining the firms would create crossover exposure likely to invite review by the Committee on Foreign Investment in the United States and other security bodies, and regulators could require operational firewalls or other conditions.

Operational and compliance differences would complicate integration. Tesla must meet automotive safety, consumer and international trade rules, while SpaceX must comply with International Traffic in Arms Regulations and defense-related controls. Aligning those compliance regimes would extend approval timelines, increase legal work and raise costs.

Investor response will depend on deal terms, governance arrangements and any regulatory conditions imposed during review. The final effect on shareholders will hinge on the transaction structure and the scope of any required operational or voting safeguards.
