Elon Musk discussed the potential merger of Tesla and SpaceX during the All-In Summit on September 15, 2026. Analysts from Wedbush and Deepwater note increasing collaboration between the firms, with estimates suggesting an 80-90% probability of a merger by 2027.
Operational integration between the companies includes the Terafab semiconductor project and the integration of Starlink satellite internet into Tesla vehicles. In February 2026, SpaceX acquired xAI, a startup in which Tesla had previously invested $2 billion.
SpaceX completed its IPO in June 2026, which simplified the potential mechanics of a stock-for-stock merger. Musk noted that any formal combination would require board approvals, shareholder votes, and extensive regulatory review.
A potential deal faces significant antitrust scrutiny due to the scale of the companies and their government contracts. These include agreements with NASA and the Department of Defense, alongside federal electric vehicle tax credits.
