SpaceX and Tesla have set up special committees to examine a potential transaction. Musk announced the move on Tuesday during SpaceX’s quarterly earnings webcast. The process has taken an important step beyond market speculation into formal evaluation, although transaction terms remain unagreed.
Approximately $2 trillion is SpaceX’s current valuation. Tesla’s market capitalisation stands close to $1.5 trillion, placing both among the world’s most valuable businesses. Adding their current valuations gives approximately $3.5 trillion. If a merger goes ahead, that combined value could make it the largest corporate merger in history.

Combining the businesses would generate significant value, Musk said on the webcast, particularly through the substantial benefits of joint superintelligence software development. As chief executive officer of both companies, he acknowledged a conflict of interest and said he would stay out of the special committees’ discussions. Finalising a transaction remains a distant prospect: the committees have not yet agreed on terms.
Artificial intelligence ambitions shared by the companies are a key driver of the integration discussions. Musk wants to connect superintelligence software with businesses covering chips, robotics, autonomous vehicles and satellite internet. Through collaboration across these fields, he hopes to create greater technological and commercial value.
Under a completed merger, a single company would house Tesla’s electric vehicle, energy and robotics businesses alongside SpaceX’s rocket launch and satellite internet operations. Investment in areas such as AI infrastructure and data centres could also be coordinated between the businesses.
Investors should not assume a merger is certain, Musk explicitly cautioned. A key hurdle is shareholder approval. At Tesla, shareholders representing 50% of all shares would need to support the transaction, rather than a simple majority of shares voted. Approval could therefore fail even with support from most shareholders who actually vote.
No specific terms have been agreed as the special committees continue their evaluation of a potential transaction. Whether a deal involving a combined corporate value of approximately $3.5 trillion comes to fruition depends on their findings, the transaction structure and shareholders’ views.
Market Insight: A Foundation for Integration
Existing business links give SpaceX and Tesla a foundation for further integration. Their investor bases overlap, and some personnel hold positions at both businesses. More than $100 million worth of Tesla Cybertrucks have previously been purchased by SpaceX. Tesla also counts Musk’s AI company, xAI, among the major customers for its large-scale energy storage batteries.
