Elon Musk Says SpaceX and Tesla Could Be Better Together, but a Trillion-Dollar Merger Faces a Shareholder Test He Cannot Control

For months, investors had speculated that Elon Musk might eventually combine SpaceX, his aerospace company, with Tesla, the electric-vehicle manufacturer. That possibility moved closer to reality on October 20, 2026, when Musk confirmed that both companies had established special committees to examine a potential merger. The Yahoo Finance report from The Motley Fool highlighted Musk’s support for the idea while explaining why a transaction of this scale could encounter serious obstacles.

The announcement was more significant than another round of speculation because it confirmed that the companies were formally examining a combination. In its October 20 report, Reuters detailed Musk’s comments during SpaceX’s third-quarter earnings call and the formation of the two committees. His endorsement gave the proposal momentum, but neither company announced a completed agreement or a final set of terms.

SpaceX’s filing makes the uncertainty explicit

SpaceX’s latest quarterly filing confirms that its board created a special committee to evaluate a potential combination with Tesla. The filing also acknowledges that Tesla established its own committee to examine the possibility. In its Form 10-Q filed with the Securities and Exchange Commission, SpaceX states that its committee has not reached a determination about whether to proceed.

The filing sets out several additional requirements before a transaction could happen, including approval from the committee, the SpaceX board and its controlling shareholder. It also warns that there is no guarantee an agreement will be reached or that a transaction will ultimately close. Those conditions are important because they establish the difference between exploring a major corporate move and committing to carry it out.

Tesla’s filing reveals that a merger is only one possibility

Tesla’s own regulatory filing describes its special committee as a group of disinterested directors tasked with exploring ways to deepen the company’s relationship with SpaceX. The Tesla quarterly report filed with the SEC says those arrangements could include a business combination, but does not limit the discussions to a merger. The wording leaves room for the committee to examine other forms of cooperation before recommending any transaction.

The filing also documents a financial connection that already exists between the businesses. After SpaceX acquired Musk’s artificial intelligence company xAI in February 2026, Tesla’s previously arranged $2 billion investment in xAI was converted into an opportunity to acquire SpaceX shares, which Tesla completed on March 12. That existing investment adds another layer to the relationship, meaning the companies must consider not only future business opportunities but also their current financial connections.

Musk’s support comes with an unusual limitation

Musk leads both companies and holds substantial interests in each, making his involvement particularly sensitive in negotiations between them. During the SpaceX earnings call, he explained that he could not participate in the committees’ discussions because he was a conflicted party. The transcript of SpaceX’s third-quarter earnings call records his explanation of why the two groups of directors would have to conduct their work without him directly taking part.

Musk nevertheless made his preference clear, describing a merger as a potentially worthwhile idea while acknowledging that the decision was not his alone. He also confirmed that the committees had not agreed on transaction terms and that an agreement was not guaranteed. His position therefore creates a distinction between advocating for the strategic vision and having authority over the process that would determine whether it becomes reality.

Tesla shareholders face a potentially difficult voting hurdle

Even if the committees reach an agreement, Tesla’s shareholder approval requirement could become one of the most important obstacles. Musk told investors that a transaction would require support representing 50% of all Tesla shares, rather than simply a majority of the shares actually voted. In its October 21 analysis of Wall Street’s expectations, Reuters highlighted how that requirement could make shareholder participation and the deal’s financial terms decisive factors.

Investors also disagree about how much additional value Tesla shareholders might demand before agreeing to exchange their stakes for ownership in a combined company. Reuters reported that estimates of the potential premium ranged from none at all to 35%, a spread that could translate into hundreds of billions of dollars. These figures represent analysts’ expectations, not prices that SpaceX and Tesla have negotiated or offered to their shareholders.

The proposed merger’s valuation remains a moving target

The financial scale of the potential transaction helps explain why investors are watching the discussions so closely. CBS News reported that SpaceX was valued at approximately $1.98 trillion while Tesla’s market capitalization stood at roughly $1.5 trillion. The report also quoted analyst Dan Ives, who estimated that a combined company could approach $5 trillion if Tesla shareholders required a substantial premium to approve the deal.

Those estimates should not be mistaken for an agreed purchase price or a confirmed valuation of the proposed combined business. The final figure would depend on the transaction structure, the relative value assigned to each company and the amount of ownership each company’s shareholders received afterward. Until the committees publish actual terms, even a seemingly precise trillion-dollar estimate remains an illustration of the deal’s potential scale rather than a price investors can rely on.

Artificial intelligence and chips provide the clearest strategic connection

One of the strongest arguments for bringing the businesses together is their growing interest in artificial intelligence and the computing infrastructure needed to support it. During his earnings call, Musk identified AI software, chip design, robotics and connectivity as areas where the companies could benefit from closer cooperation. An Axios report on the formal merger discussions likewise described the companies’ expanding overlap in AI and chip-related projects.

Combining the companies could make it easier to coordinate investments across these related technological priorities. It could also allow the businesses to pursue shared projects without relying as heavily on separate corporate decision-making processes. Whether that approach would create enough additional value to justify a merger, however, remains an unanswered question that the committees would need to evaluate.

Terafab and robotics could bring their longer-term ambitions closer together

A project known as Terafab illustrates how the companies’ future plans could intersect. Musk has discussed the proposed chip-manufacturing initiative as a way to support enormous computing requirements, and a merger could make coordination of that effort more straightforward. An Axios analysis published before the formal announcement cited Barclays analysts who viewed AI as a central reason a Tesla-SpaceX combination might make strategic sense.

Tesla’s potential contribution to such a relationship extends beyond electric vehicles to autonomous-driving technology and humanoid robots. SpaceX, meanwhile, brings aerospace engineering, satellite communications and growing computing-related activities. These businesses could complement each other, but the existence of a shared technological vision would not automatically solve the engineering, manufacturing and commercial challenges each project faces.

SpaceX’s latest earnings strengthened the financial backdrop

The merger discussions emerged as SpaceX reported a particularly strong third quarter. According to the Associated Press’s coverage of the company’s earnings, revenue reached $14.6 billion for the three months ending September 30, 2026, representing a 161% increase from the same period a year earlier. Net income reached $4.4 billion, reversing a loss in the comparable quarter of 2025.

The results also highlighted how much SpaceX’s business has expanded beyond rocket launches. Its AI business became the company’s largest source of revenue during the quarter, while Starlink remained its largest profit generator. This combination of computing services and satellite connectivity adds a different dimension to SpaceX’s financial profile as investors consider how its assets might fit alongside Tesla’s vehicle, software and robotics ambitions.

Rapid growth does not eliminate the financial risks

The companies’ ambitious plans also require substantial spending, and that is an important part of the potential merger’s risk profile. A Business Insider analysis of the proposed combination examined the possibility that investors could gain access to complementary businesses while also becoming exposed to each other’s financial and operational challenges. It highlighted questions surrounding SpaceX’s investment requirements and Tesla’s efforts to expand its autonomous-driving business.

SpaceX’s plans involve expanding computing capacity and advancing Starship, while Tesla is pursuing autonomous vehicles and humanoid robots. Some technologies central to the companies’ future valuations have not yet reached commercial scale, making their ultimate financial contributions uncertain. A combined company might be able to coordinate spending more effectively, but it would also place more of those ambitions within the same corporate structure.

Musk’s public endorsement could complicate the negotiation process

The committees are supposed to evaluate the transaction independently, but Musk’s public support has raised concerns about how the negotiations will be perceived. A Reuters investigation published on October 22 reported that people familiar with the discussions worried his remarks could invite greater shareholder scrutiny and delay the process by several weeks. Those concerns reflect the views of people involved in the discussions, not confirmation that the merger has been derailed.

The report also drew comparisons with Tesla’s 2016 acquisition of SolarCity, which resulted in years of litigation over Musk’s role in that transaction. Reuters reported that advisers were considering different possible structures for the new transaction, including a SpaceX acquisition of Tesla or a merger under a newly created holding company. It also described discussions about different forms of consideration, but none of those possibilities had become an agreed proposal.

Antitrust scrutiny could depend on who gets access to the technology

Even a transaction supported by both boards and their shareholders could attract competition-related questions. A Semafor report on possible antitrust scrutiny described a concern that a combined company might eventually use access to technology such as Starlink to favor Tesla or limit access for competing electric-vehicle and autonomous-driving businesses. That is a potential regulatory issue rather than a finding that either company has already engaged in such conduct.

The actual risk would depend on the structure of a deal and the way the combined company handled its products and infrastructure. Regulators could examine whether connecting satellite communications with vehicles, robotics or AI services would disadvantage competitors or restrict access to important technologies. Because the terms remain unknown, the possible antitrust consequences cannot yet be determined.

Cross-border operations and national security add another layer

The companies also operate in different regulatory environments, which could complicate any effort to combine them. Morningstar’s analysis of the merger discussions warned of potential regulatory risks involving both the United States and China, citing SpaceX’s role as a U.S. defense contractor and Tesla’s manufacturing operations in China. Such considerations could require scrutiny beyond the shareholder and corporate-governance issues already facing the proposed transaction.

A combination could bring defense-related space infrastructure into the same corporate group as an automaker with extensive international operations. That prospect makes government review an additional issue to consider rather than a procedural formality that can be assumed away. There is no basis yet to conclude whether regulators would approve, challenge or impose conditions on a transaction that has not been agreed.

Tesla’s earnings call produced no new merger details

Investors hoping for a clearer explanation of the possible deal did not receive one during Tesla’s October 21 earnings call. According to MarketWatch’s account of the call, Tesla’s head of investor relations said the company would not address questions about a potential SpaceX merger that day. The call therefore did not provide a proposed price, an exchange ratio or a timetable for completing a transaction.

MarketWatch reported that Tesla shares fell in premarket trading on Thursday, October 22, after investors were left without further clarity. That reaction reflected the market’s response to uncertainty, but it did not establish whether a merger would ultimately proceed. The central questions remained unresolved because the committees had not yet produced terms for shareholders to consider.

The next meaningful development will be a proposal investors can evaluate

The next stage depends on whether the committees can turn the strategic arguments into a transaction they believe is in the interests of their respective shareholders. Any proposal would need to specify the structure of the combination, the treatment of existing ownership and the financial terms offered to investors. The relevant boards, shareholders and regulators would then have their own roles in determining whether the transaction could move forward.

For investors, the unanswered questions include how much Tesla shareholders would receive, how ownership and voting power would be divided, and how the combined company would finance its ambitious projects. Musk has publicly argued that cooperation between the businesses could be valuable, but the companies’ filings make clear that no completed deal is assured. For now, the most important development is not the endorsement itself, but whether the independent committees can produce terms that both companies and their shareholders are prepared to accept.
