Tesla and SpaceX have formed separate independent board committees to review a possible merger, but no terms have been agreed.
Why the companies might fit
Tesla’s plans now include autonomous vehicles, robotics and artificial intelligence. SpaceX has expanded beyond rocket launches into Starlink and AI computing. Tesla invested about $2 billion in Musk’s AI company, xAI, which SpaceX later acquired. The companies are also working on Terafab, a planned chip-making project for Tesla’s vehicles and robots and SpaceX’s computing needs.
Musk says common ownership could make it easier to share software, chips, robotics, connectivity and computing resources. A single company could move money, engineers and equipment between projects without separate negotiations. But these are possible benefits, not proven savings: the companies could keep working together through contracts and joint projects without merging.
Who would set the terms
Musk runs both companies and has a large financial stake in each. He says he is excluded from committee discussions because he has a conflict of interest. The committees are made up of independent directors, but their members and advisers have not been publicly identified. Ira Ehrenpreis is an independent director at both companies, but there is no indication he is on either deal committee.
The combined company has been estimated at about $3.5 trillion. Reuters reported that Wall Street estimates of a possible premium for Tesla shareholders range from none to 35 percent. The committees would need to assess each company’s value and negotiate an exchange ratio, which would determine how much of the combined company each group owns. Musk owns nearly a fifth of Tesla and has voting control at SpaceX, so a merger could increase his influence, depending on its structure.
What investors and regulators face
Tesla investors would gain access to SpaceX’s launch and satellite businesses, while taking on more costly, technically demanding projects. SpaceX investors would gain a stake in Tesla’s vehicles, energy storage and robotics, along with the automaker’s risks. The committees must decide whether the businesses strengthen one another and whether a deal would share the value fairly.
Under current U.S. rules, mergers above set size thresholds must be reported for antitrust review and cannot close until a waiting period ends. The 2026 transaction-size threshold is $133.9 million. The FTC or Justice Department could challenge a deal if they concluded it would harm competition, though neither has publicly laid out a case against this proposal. Musk said Tesla needs support from holders of 50 percent of all outstanding shares, not just a majority of those who vote; he called this a high hurdle. Musk controls a majority of SpaceX’s voting power.
The committees’ next steps are to review valuations, possible deal structures and whether shareholders would benefit. Tesla’s December 3 annual meeting is not a merger vote, and its proxy lists no such proposal. The companies have given no timetable. If the committees agree on terms, disclosures, shareholder votes and regulatory review would follow. If they do not, the companies can continue their joint projects while remaining separate.
