SpaceX-Tesla Merger Speculation Grows as Musk Pushes SpaceX Toward Historic Nasdaq Debut

Elon Musk’s expanding technology empire is once again fueling speculation about a possible merger between SpaceX and Tesla as the rocket company moves closer to a highly anticipated public listing.

SpaceX is expected to begin trading on the Nasdaq within weeks after securing a private valuation of approximately $1.25 trillion earlier this year following its merger with Musk’s AI startup xAI. Tesla, meanwhile, currently carries a market capitalization of roughly $1.6 trillion.

The prospect of combining two of Musk’s most valuable companies has increasingly become a topic of discussion among employees, investors and industry insiders. According to people familiar with internal conversations, Musk has discussed the possibility of integrating the businesses more closely as both companies become increasingly centered around artificial intelligence infrastructure and computing capabilities.

Employees at Tesla reportedly view such a transaction as plausible given the extensive operational overlap already in place between the two firms.

Although SpaceX and Tesla operate in very different industries — aerospace and electric vehicles — both companies now share a growing dependence on AI systems, advanced computing power and specialized engineering talent.

SpaceX disclosed that more than three-quarters of its $10.1 billion in first-quarter capital expenditures were tied to AI-related investments. Tesla has also dramatically increased spending, saying its capital expenditures are expected to exceed $25 billion this year as it accelerates development of autonomous driving systems and AI infrastructure.

Industry experts note that both companies face similar technological challenges despite their different markets.

Tesla must develop powerful AI systems capable of functioning reliably inside moving vehicles under tight power and cooling constraints. SpaceX, meanwhile, faces similar engineering problems in orbit, where computing systems must withstand radiation exposure, thermal extremes and severe energy limitations.

The companies have already spent years sharing resources, personnel and suppliers.

Several executives and board members hold roles across both organizations, while engineering collaboration between the firms has become increasingly common. Tesla has previously supplied solar technology and vehicle components to SpaceX, while SpaceX has supported Tesla on advanced materials engineering projects.

More recently, SpaceX revealed in its IPO filings that it purchased nearly $700 million worth of Tesla Megapack battery systems to support xAI data centers in Memphis. The company also disclosed spending over $130 million on Tesla Cybertrucks during 2025.

Tesla itself invested $2 billion into xAI earlier this year before the AI company merged into SpaceX.

Suppliers increasingly view Musk’s companies as a unified ecosystem rather than separate businesses. Nvidia reportedly redirected a major GPU shipment from Tesla to xAI at Musk’s request last year as the entrepreneur prioritized AI infrastructure expansion.

The potential strategic logic behind a merger has attracted growing attention in Silicon Valley. Supporters argue that a combined company could more efficiently compete against rivals such as Google, OpenAI and other AI leaders by pooling capital, computing resources and engineering talent.

However, such a deal would likely face enormous structural and governance complexities.

Questions remain about how ownership would be structured, which company would serve as the parent entity, and how shareholders would evaluate the relative value of each business.

Still, analysts believe regulatory antitrust concerns may be less severe than in other megadeals because the two companies operate in largely different industries.

For Musk personally, a merger could significantly expand his influence over artificial intelligence, transportation, aerospace and communications simultaneously. SpaceX’s compensation structure reportedly includes ambitious milestones tied to multi-trillion-dollar valuations and even long-term Mars colonization goals.

Investors are now closely watching SpaceX’s upcoming roadshow, which is expected to offer deeper insight into how Musk positions the company’s future — and whether its long-term trajectory may eventually converge with Tesla’s.

As AI increasingly becomes the common thread connecting Musk’s businesses, speculation around a future combination of SpaceX and Tesla is unlikely to fade anytime soon.
