Merging SpaceX and Tesla would be a "good idea," Musk says

What changed

Elon Musk said SpaceX and Tesla are considering a merger, calling the idea a “good idea” during SpaceX’s third-quarter earnings call on October 20, 2026. Both companies have formed special committees of independent directors, but no terms or agreement exist; shareholders would ultimately decide whether a deal goes ahead.

Why it matters

This is more than a space company absorbing a carmaker. Musk is trying to align two businesses he says are moving toward overlapping needs: artificial intelligence, chips, robotics, energy and connectivity. SpaceX has also acquired xAI and gone public this year, making the proposed merger part of a broader consolidation of Musk’s technology empire.

The numbers explain the attraction. SpaceX was valued at about $2 trillion and Tesla at about $1.5 trillion when Musk spoke. Musk holds more than 82% of SpaceX’s voting power, compared with about 20% at Tesla. A merger could therefore give him much greater control of the combined company, depending on the valuations and deal terms shareholders negotiate.

That is also why Tesla investors may look closely at the exchange ratio and governance structure. Musk said 50% of all Tesla shareholders would need to approve the transaction, not merely holders of voting shares. The independent committees are meant to handle those negotiations while Musk stays out because he is a conflicted party.

The practical case still has to be proved. SpaceX says future revenue could center on orbital data centers for artificial-intelligence computing, while Tesla is pursuing self-driving cars, robots and industrial hardware. Those ambitions may share chips, power and connectivity, but the committees have not established that combining the companies would produce measurable benefits.

US regulators will scrutinize the proposal, and some political leaders may object to concentrating even more influence in one Musk-controlled corporation. For now, the merger is an idea under negotiation, not a transaction.
