Musk pitches Tesla-SpaceX merger after SpaceX S&P 500 denial

Bloomberg reported that Elon Musk is pitching a merger between SpaceX and Tesla as a way to give SpaceX a path into the S&P 500, months after the index provider denied SpaceX a swift entry. Tesla is already a major S&P 500 constituent, so combining the companies could bring SpaceX’s operations inside an existing index member without a separate listing or index vote.

The S&P 500 is a U.S. stock index used by many funds to track large companies, so inclusion can create automatic buying demand. SpaceX’s reported denial had left it outside that flow despite its role in launch services and government contracts. A Tesla merger would not by itself guarantee index treatment, but it would place SpaceX within a company already weighted heavily in the benchmark.

The pitch connects corporate structure to government-adjacent infrastructure. SpaceX is central to U.S. satellite launch and communications, while Tesla is a consumer industrial company. A merger would require shareholder approvals and regulatory review, and the proposal raises questions about disclosure, conflicts and concentration of control under Musk. Bloomberg did not detail the proposed terms or whether either board had formally accepted the idea.

The significance is structural. A combination between a private aerospace and satellite business and a listed automaker would change how investors value both sectors and how index providers treat hybrid industrial groups. It also shows how a denial of direct S&P inclusion can push a larger corporate reorganization, with effects on shareholders, fund flows and regulatory oversight in the United States and globally.
