As SpaceX's listing approaches, a potential consolidation of unprecedented scale in the tech sector is moving from market speculation to more serious discussion. It is reported that Elon Musk, the world's richest person, has discussed with colleagues the possibility of merging SpaceX and Tesla (TSLA.US). With SpaceX expected to debut on the Nasdaq in just over two weeks, speculation that "Musk will ultimately combine his two core companies" is spreading on Wall Street.
**Laying the Groundwork for the Largest IPO Ever** SpaceX's IPO is undoubtedly the most anticipated event in global capital markets for 2026. On May 20, SpaceX formally filed its prospectus with the SEC, planning to list on the Nasdaq under the ticker "SPCX" with a dual listing on the Nasdaq Texas exchange. The roadshow will begin on June 4, with pricing on June 11 and the official listing on June 12. The valuation target for this IPO is staggering. Market estimates suggest SpaceX is aiming for a valuation between $1.75 trillion and $2 trillion, with a potential fundraising size of up to $75-$80 billion. If successful, this would be the largest IPO in global financial history, more than double the record set by Saudi Aramco's $29.4 billion offering in 2019. The underwriting syndicate is equally impressive, including Goldman Sachs, Morgan Stanley, JPMorgan Chase, Bank of America, and Citigroup.
SpaceX already commands a $1.25 trillion valuation in the private market, a figure bolstered by its full acquisition of xAI and the social platform X in February. Through this all-stock, tax-free transaction, SpaceX (valued at $1 trillion at the time) incorporated the two-year-old xAI (valued at $250 billion). The combined SpaceX now operates across three segments: Aerospace, Connectivity, and Artificial Intelligence. The prospectus reveals that SpaceX's consolidated revenue for the 2025 fiscal year reached $18.67 billion, with adjusted EBIT of $6.58 billion, but it reported a final net loss of $4.94 billion. The loss was primarily driven by massive investments in AI—xAI's capital expenditures in 2025 amounted to $12.73 billion, mainly for purchasing Nvidia (NVDA.US) chips and building the Colossus supercomputing center in Memphis, resulting in a $6.36 billion operating loss for its AI division that year. In 2026, AI-related investments have intensified further, with the AI segment accounting for over three-quarters of the company's total $10.1 billion in Q1 capital expenditures.
Meanwhile, Tesla currently holds a market capitalization of approximately $1.6 trillion. This means that post-SpaceX's listing, Musk would simultaneously helm two super-enterprises ranking within the top ten in U.S. market value. It is this unprecedented scale that has suddenly amplified the imagination around a potential merger.
**Rumors Move from Internal to Public** The reason this merger speculation is attracting far more attention than before is the belief that Musk himself has participated in these discussions. According to informed sources, SpaceX and Tesla already share numerous resources, and Musk has indeed discussed the possibility of integrating the two companies with colleagues. While rumors have circulated for months, Musk's personal involvement undoubtedly lends more realistic possibility to the prospect. Notably, this topic is reportedly not a secret within Tesla. A current Tesla employee stated that many employees have long expected such a transaction to eventually happen, and the subject is openly discussed internally. Another source close to the companies pointed out that shared challenges regarding power and computing limitations have driven frequent collaboration in recent years.
Former engineer and now Theory Ventures investor, Tomasz Tunguz, offered a succinct summary: "Tesla must run powerful AI systems in moving vehicles, subject to strict constraints on power, thermal management, latency, reliability, and cost. SpaceX must consider in-orbit computing, where radiation, thermal cycling, launch mass, power generation, and heat dissipation become critical design constraints." In his view, both companies are essentially tackling computing challenges under extreme conditions.
**Resource Sharing and Personnel Intertwining** The persuasiveness of the merger rumors stems from the already deeply interconnected resource network between SpaceX and Tesla. On the personnel front, the crossover is nearly seamless. Musk himself serves on the boards of both companies. His brother, Kimbal Musk, is a current Tesla board member and previously served on SpaceX's board. Ira Ehrenpreis, founder of venture capital firm DBL Partners, sits on both boards. SpaceX board members Antonio Gracias and Steve Jurvetson have also previously served on Tesla's board. Charles Kuehmann simultaneously serves as Vice President of Materials Engineering at both Tesla and SpaceX; this senior engineer, who joined from Apple (AAPL.US) a decade ago, is known for his significant contributions to solving critical design problems.
On the capital front, Tesla announced a $2 billion investment in xAI in January. The following month, as SpaceX completed its merger with xAI, Tesla's stake in xAI was converted into a holding in SpaceX, effectively making Tesla a shareholder in SpaceX. While this stake represents less than 1% of SpaceX's anticipated valuation, it financially links the two companies.
In terms of business, the scale and depth of transactions are even more remarkable. SpaceX's prospectus discloses that the company purchased $697 million worth of Tesla Megapack battery storage systems in 2024 and 2025 to power xAI's Colossus supercomputing facility data center in Memphis, Tennessee. Additionally, SpaceX purchased $131 million worth of Tesla Cybertrucks in 2025 at the manufacturer's suggested retail price. Past collaborations have also included Tesla selling solar equipment and auto parts to SpaceX, Tesla's use of SpaceX private jets, and SpaceX developing special alloy materials for the Tesla Cybertruck. Statistically, the term "Tesla" appears 87 times in the SpaceX prospectus, compared to "Musk" appearing 174 times.
On the supply chain level, some suppliers reportedly view the two companies as a single client. A telling incident occurred in 2024 when Musk personally intervened to have Nvidia redirect a $5 billion GPU order originally destined for Tesla to xAI.
**Analyst Prediction: 2027 Could Be a Key Milestone** Shortly after the SpaceX prospectus was released, prominent Wall Street analysts quickly offered a predicted timeline. Dan Ives, a tech analyst at Wedbush, stated in a research note: "We continue to believe that SpaceX and Tesla will ultimately merge into one company by 2027, with the foundation for operational integration already in place." Ives further analyzed that Musk's strategic goal is to "own and control more of the AI ecosystem, and combining SpaceX and Tesla in some form will be the key link connecting these two disruptive tech giants to lead the AI revolution."
Supporting this judgment is not just strategic logic but concrete business cooperation. In March 2026, Musk announced that SpaceX, xAI, and Tesla would jointly build a large chip manufacturing plant named "Terafab," aimed at producing AI chips for Tesla's self-driving taxis and humanoid robots. Ives believes the announcement of this joint project could be the first step towards a merger between Tesla and SpaceX.
Ross Gerber, CEO of investment firm Gerber Kawasaki, stated that integrating SpaceX and Tesla would help Musk realize his long-held ambition of operating a super-company and make it easier to raise and allocate the vast capital needed to compete with tech giants like Google in the AI arena. Tejpaul Bhatia, CEO of Nebex and a long-term SpaceX investor, noted: "I think it's proven by Elon himself—parallel entrepreneurship seems to work for him." For investors supportive of a merger, consolidating SpaceX and Tesla under a single corporate structure could significantly improve resource allocation efficiency and accelerate the implementation of AI strategy. By unifying capital, technology, and data systems, this combination could potentially create the most valuable tech giant in history. Some market analysts have even playfully dubbed this potential merger the birth of "Elon Inc." According to the latest data from prediction market platform Kalshi, the probability of a SpaceX-Tesla merger by March 1, 2027, is 37%.
**Legal Challenges and Governance Structure** While business synergies and strategic logic seem clear, a merger of this scale faces equally significant technical and legal challenges. Legal experts suggest that a SpaceX-Tesla merger might not raise serious antitrust issues, as the two companies have little direct competition in their core businesses. The real difficulties lie in aligning shareholder interests. Experts point to several thorny issues: which company would be the surviving entity (the parent), the exchange ratio for the stock swap, and who determines fair valuations for both sides. Informed sources indicate that determining SpaceX's valuation is the primary hurdle—its valuation remains subject to significant fluctuation until the IPO is complete. How to establish a share exchange ratio satisfactory to shareholders of both companies during merger negotiations will directly impact the deal's success.
However, on the SpaceX side, Musk is expected to face limited board resistance. The prospectus reveals that SpaceX has a dual-class share structure, with Musk holding approximately 85% of the voting power. It also explicitly states in the risk factors section that SpaceX is a "controlled company," meaning its Class A shareholders "will not have the same protections afforded to stockholders of companies that are subject to all of Nasdaq's corporate governance requirements."
On the Tesla side, shareholders approved a 12-tranche compensation plan in late 2024, with each tranche's vesting tied to market cap growth and operational achievements. Should a merger proceed, reconciling this compensation plan with SpaceX's incentives for Musk (which include targets like reaching a $7.5 trillion market cap and establishing a colony of at least 1 million residents on Mars) presents another complex puzzle. It is important to note that representatives for both SpaceX and Tesla have not publicly commented on the merger speculation.
**The Future Vision: AI-Driven Super Consolidation** Beyond the technical details of a potential merger, the broader trend reflected in these rumors is more noteworthy. On the surface, a company launching rockets on government contracts and an electric vehicle manufacturer might seem to have little in common. However, both are increasingly focused on AI and the talent and computing resources needed to build AI infrastructure and services. As mentioned, over three-quarters of SpaceX's $10.1 billion Q1 2026 capital expenditures were AI-related. Tesla stated in its latest earnings report that its capital expenditures this year would roughly triple to exceed $25 billion, supporting new factory construction and AI-related infrastructure.
Integrating the narratives of space and AI is precisely the key factor supporting SpaceX's lofty $1.75-$2 trillion valuation target. Commercial launches and satellite broadband alone would likely struggle to justify such a high valuation to investors. But by adding the AI label and weaving a "space-based computing power" narrative, SpaceX's entire valuation framework undergoes a fundamental transformation.
From this perspective, a potential Tesla-SpaceX merger is not merely an expansion of corporate scale but a strategic step in Musk's plan to build a super-ecosystem spanning ground-based electric mobility, space transportation, satellite communications, and AI computing infrastructure. As Ives stated: "Musk wants to own and control more of the AI ecosystem, and combining SpaceX and Tesla in some form will be the key link connecting these two disruptive tech giants."
