SpaceX and Tesla are making progress in discussions over a potential merger that could bring two of Elon Musk’s largest companies under a single corporate structure. According to a Bloomberg News report cited by Reuters on November 12, 2026, the companies could announce an agreement as early as December, although an alternative timeline involving an announcement in early 2027 is also being considered. The proposed transaction could become one of the largest corporate mergers in history.
The potential combination would bring together Tesla’s electric vehicles, energy storage, robotics and artificial intelligence operations with SpaceX’s rockets, satellite communications and space infrastructure businesses. Based on their reported market capitalisations at the time, SpaceX was valued at approximately $1.90 trillion, while Tesla was worth around $1.55 trillion, putting their combined value at approximately $3.45 trillion. However, the merger is still under discussion and faces significant regulatory, governance and shareholder approval challenges.
SpaceX and Tesla Merger Negotiations Make Progress
According to Bloomberg, discussions between SpaceX and Tesla have advanced, with the companies’ boards and advisers working through potential transaction terms and the governance structure of a combined business.
The companies are considering announcing the transaction as early as December 2026.
However, an alternative scenario would push the announcement into early 2027.
The discussions follow Elon Musk’s comments during SpaceX’s third-quarter earnings call in October, when he described a potential merger with Tesla as a good idea.
Musk also confirmed that both companies had established special committees comprising independent directors to evaluate the proposed combination.
These committees are important because a transaction involving two companies controlled by the same influential executive requires careful consideration of shareholder interests, conflicts of interest and corporate governance.
Neither SpaceX nor Tesla immediately commented on the latest report.
Although negotiations have progressed, there is no guarantee that the companies will ultimately complete a merger.
Combined Valuation of SpaceX and Tesla Could Reach $3.45 Trillion
The potential transaction would bring together two companies with substantial valuations and businesses operating across several major industries.
According to Reuters, SpaceX had a market capitalisation of approximately $1.90 trillion, while Tesla was valued at around $1.55 trillion as of the previous market close.
Together, their valuations would amount to approximately $3.45 trillion.
| Company | Reported Market Capitalisation |
|---|---|
| SpaceX | $1.90 Trillion |
| Tesla | $1.55 Trillion |
| Combined Value | $3.45 Trillion |
The proposed merger could create a diversified technology and infrastructure group with exposure to electric mobility, artificial intelligence, autonomous systems, satellite connectivity and aerospace.
However, the combined valuation should not be interpreted as the final valuation of a merged company. The transaction’s structure, exchange ratio and financial terms have not been disclosed.
One of the important questions under discussion is how many shares SpaceX would need to offer Tesla shareholders as part of the transaction.
The final arrangement would determine how ownership is distributed between existing investors in both companies.
Why Does Elon Musk Want to Combine SpaceX and Tesla?
The proposed merger could bring several of Musk’s major technology ambitions together under one corporate structure.
Although Tesla and SpaceX operate in different industries, both companies are increasingly investing in artificial intelligence, computing infrastructure and advanced manufacturing.
A combination could create opportunities for collaboration across several business areas.
1. Artificial Intelligence and Computing Infrastructure
Artificial intelligence is becoming an increasingly important part of both companies’ strategies.
Tesla is developing AI systems for autonomous driving, its robotaxi business and humanoid robotics.
SpaceX has also expanded its involvement in AI infrastructure through its growing computing capabilities and partnerships with AI companies.
Combining the businesses could create opportunities to coordinate investment in computing infrastructure, semiconductor development and AI applications.
2. Robotics and Autonomous Technology
Tesla is developing its Optimus humanoid robot programme alongside autonomous driving technology.
The company wants to use robotics to automate manufacturing and eventually develop commercial humanoid robots.
SpaceX also relies heavily on robotics and automation for spacecraft manufacturing, launch operations and other engineering activities.
A combined organisation could potentially share expertise in robotics, manufacturing systems and AI software.
3. Satellite Connectivity and Autonomous Vehicles
SpaceX operates Starlink, its satellite internet service, which provides broadband connectivity through a network of satellites in low Earth orbit.
Tesla manufactures electric vehicles and is developing autonomous driving technologies.
A combination could create opportunities to explore satellite connectivity for vehicles, particularly in regions where conventional mobile networks have limited coverage.
However, such applications would require technical development, regulatory permissions and commercially viable service models.
4. Space-Based Data Centres
One of the longer-term opportunities involves the development of computing infrastructure in space.
As demand for AI computing increases, companies are exploring alternative ways to access energy and computing resources.
SpaceX’s launch capabilities and satellite infrastructure could potentially support future space-based computing projects.
Tesla’s expertise in batteries, energy storage and AI could also become relevant to such initiatives.
However, large-scale space-based data centres remain an emerging concept rather than an established commercial business.
Terafab Chip Manufacturing Venture Connects SpaceX and Tesla
SpaceX and Tesla already have a significant business connection through Terafab, their joint semiconductor manufacturing initiative.
The project is designed to develop advanced chips that could support artificial intelligence, robotics, autonomous systems and other computing applications.
During SpaceX’s third-quarter earnings call, Musk said Terafab expects to produce its first test chip around May or June 2027.
The venture is targeting volume production by the third quarter of 2028.
The project highlights the importance both companies place on securing access to advanced semiconductor technology.
AI development requires increasingly powerful processors, while autonomous vehicles and robotics also depend on specialised chips capable of handling complex computing workloads.
Terafab could help strengthen their access to semiconductor manufacturing capabilities.
The joint venture also demonstrates that the two businesses are already collaborating in areas that extend beyond their traditional industries.
Regulatory Challenges Could Complicate the SpaceX-Tesla Merger
Despite the potential business synergies, combining SpaceX and Tesla would present substantial regulatory challenges.
One of the biggest concerns involves SpaceX’s US government and defence contracts.
SpaceX plays an important role in America’s aerospace and national security infrastructure through its rocket launches, satellite communications and other government-related services.
Its contracts with US government agencies could create additional scrutiny over ownership, control and access to sensitive technology.
Tesla, meanwhile, has significant manufacturing and commercial operations in China.
The company relies on its Chinese operations as an important part of its global business, including vehicle manufacturing and battery-related supply chains.
Combining a company with sensitive US defence contracts and another with substantial exposure to China could raise questions involving national security, data access and foreign business interests.
Regulators and government agencies would need to examine how these interests could be managed within a single corporate structure.
Shareholder approvals and corporate governance requirements could also complicate the transaction.
Shareholder and Governance Questions Remain Unresolved
Another important challenge is determining how the combined company would be managed.
Tesla and SpaceX have different shareholder bases, business models and financial priorities.
Tesla shareholders have exposure to electric vehicles, energy storage, autonomous driving and robotics.
SpaceX investors have exposure to aerospace, satellite communications, launch services and emerging AI infrastructure opportunities.
A merger would require an agreement on how these different businesses would be valued and represented in the combined entity.
The exchange ratio would be particularly important because it would determine how many shares investors in each company receive.
The governance structure would also need to address the responsibilities of the board, executive management and independent directors.
Because Musk has a central role in both companies, managing potential conflicts of interest will be an important part of the process.
The independent committees established by both companies are expected to examine these issues.
SpaceX and Tesla Shares React to Merger Reports
The latest merger developments have attracted attention from investors in both companies.
According to Bloomberg’s reporting, Tesla shares climbed as much as 1.9% during Thursday’s trading session following the news, while SpaceX shares also recorded gains.
Investors are assessing the potential benefits of combining the companies, including access to shared technology, manufacturing capabilities and AI infrastructure.
However, a potential merger could also create uncertainty regarding the financial structure, ownership arrangements and regulatory obligations of the combined business.
The final impact on shareholders will depend on the transaction’s terms and whether the expected business synergies justify the combination.
The Bigger Picture
A potential SpaceX-Tesla merger represents a broader shift in Elon Musk’s business strategy towards combining artificial intelligence, robotics, energy, transportation and aerospace infrastructure.
Both companies are investing heavily in technologies that could become increasingly interconnected over the coming decade.
Tesla is expanding beyond traditional vehicle manufacturing into autonomous transportation, robotics and energy storage. SpaceX has developed from a rocket manufacturer into a major aerospace and satellite communications business, while also exploring AI-related infrastructure opportunities.
Bringing these operations together could create a technology group with capabilities spanning several industries.
However, combining businesses of this scale would also introduce substantial management complexity, regulatory scrutiny and financial considerations. The success of the proposal would depend on whether the operational benefits outweigh the challenges of managing such a diversified organisation.
Looking Ahead
SpaceX and Tesla are expected to continue discussions through their independent board committees and advisers as they evaluate the potential transaction. An announcement could come as early as December 2026, although early 2027 remains another possibility. The companies still need to resolve important questions involving valuation, share exchange ratios, governance and regulatory approvals before a merger can proceed.
For investors, the next major development will be the disclosure of the proposed transaction structure and its financial implications for existing shareholders. If completed, the combination could reshape several industries, bringing electric vehicles, artificial intelligence, robotics, satellite communications and aerospace under one corporate umbrella. Until the companies make an official announcement, however, the merger remains a proposal under consideration rather than a confirmed deal.
