Elon Musk has left the door wide open for a potential merger between Tesla and SpaceX, his two most valuable companies, despite declining to directly confirm the plans during Tesla's earnings call. When asked point-blank about combining the two firms, Musk avoided a direct answer but spent considerable time explaining how SpaceX's technology could enhance Tesla's mission, a response that has Wall Street analysts significantly raising their confidence that a deal could happen within the next few years.

The question of a Tesla-SpaceX merger has been brewing for months, especially after SpaceX completed a landmark $1.25 trillion acquisition of Musk's artificial intelligence company xAI earlier this year, rebranding it as SpaceXAI. That deal was followed by SpaceX's record $75 billion initial public offering in the summer of 2026, giving the space company a public market presence and the financial firepower to pursue major strategic moves.

What Did Musk Actually Say About a Merger?

During Tesla's earnings call on Wednesday, Musk acknowledged the growing overlap between his two companies but stopped short of confirming merger plans. "As you can tell from all the many collaborations on so many fronts with SpaceX, there's more and more overlap, especially with the Terafab, that's really going to be a gigantic project," Musk explained. He then noted that "obviously, you know, we can't talk about combining companies, that kind of thing, on earnings calls".

What followed, however, sounded like a carefully crafted pitch for why SpaceX technology belongs inside Tesla's future. Musk highlighted how SpaceX's Starlink satellite internet service could provide reliable connectivity for Tesla's autonomous vehicles, including the Cybercab, even in areas with poor cellular coverage. He also emphasized the potential of integrating SpaceXAI's Grok chatbot into Tesla's Optimus robots, a project he had previously unveiled as "Digital Optimus".

Why Are Analysts Now More Confident a Merger Will Happen?

Musk's carefully worded response appears to have convinced Wall Street that a merger is increasingly likely. Gene Munster, co-founder and managing partner of investment company Deepwater, stated that his confidence in a Tesla-SpaceX combination has risen sharply. "Going into the call, I thought there was an 80% chance the two companies come together in the next few years," Munster noted in a post on X. "I'm raising that to 90%".

The analyst's shift reflects a broader market perception that Musk is laying the groundwork for a merger through strategic language and demonstrated synergies. The two companies already collaborate extensively across multiple fronts, creating a compelling case for formal integration.

How Are Tesla and SpaceX Already Working Together?

• Terafab Joint Venture: The two companies are building a massive chip factory in Texas called Terafab, which Musk described as "really going to be a gigantic project" that represents significant overlap between the firms.
• AI Integration: SpaceXAI's Grok chatbot is being integrated into Tesla vehicles, and Musk has outlined plans to incorporate Grok into Tesla's Optimus humanoid robots as part of the "Digital Optimus" initiative.
• Connectivity Solutions: SpaceX's Starlink satellite internet is positioned to provide backup connectivity for Tesla's autonomous vehicles, addressing coverage gaps in areas with poor cellular infrastructure.

These collaborations demonstrate that the two companies are already functioning as a partially integrated entity, sharing technology, infrastructure, and strategic vision. A formal merger would simply formalize what is already happening operationally.

What's Driving Tesla's Financial Pressure?

Tesla's earnings report also revealed significant financial headwinds that could make a merger more attractive from a strategic standpoint. The company is spending more than $25 billion this year, largely driven by artificial intelligence investments, which has begun to weigh heavily on its financial performance. While revenue came in above expectations, earnings per share, a key metric showing profit per share of stock, fell well below market expectations.

The company's free cash flow, a measure of how much cash a company generates after accounting for capital expenditures, turned negative in the most recent quarter due to the massive spending spree. Musk defended the aggressive spending strategy, saying he specifically instructed his team to spend money "as fast as we can without it being too wasteful," arguing that pursuing "extremely high efficiency" would only slow innovation and production.

"We're bringing an incredible amount of construction and production growth in so many different arenas simultaneously. I think probably this is the fastest industrial scale up since World War II in America," Musk declared.

A merger with SpaceX could potentially help Tesla manage these costs by consolidating operations, sharing infrastructure like Terafab, and leveraging SpaceX's revenue streams to offset Tesla's massive capital expenditures. SpaceX's public market status and strong financial position following its IPO would give the combined entity greater financial flexibility.

While Musk has not confirmed a merger timeline or even acknowledged that formal discussions are underway, his strategic comments during the earnings call have convinced analysts that the pieces are being positioned for a potential combination. Whether that happens in the next few years remains to be seen, but Wall Street is now betting heavily that it will.
