Tesla reported third-quarter results on Wednesday that showed auto revenue declining and energy revenue dropping even more sharply, but the numbers were an afterthought. The only line analysts wanted to discuss was Elon Musk's endorsement, a day earlier on SpaceX's earnings call, of a merger between his two flagship companies. "Do I think it would be a good idea? Yes," Musk said Tuesday, adding that both boards have formed special committees to explore a transaction. Tesla shares fell 3% on Thursday and are down 17% for the year. SpaceX gave back 9%, erasing its post-IPO gains and slipping below its June debut price.
The numbers that got ignored
Tesla's automotive revenue fell year over year, and the energy generation and storage segment, recently the company's highest-margin business, posted an even steeper decline. Musk has been arguing for quarters that the investment case rests on robotaxis and Optimus humanoid robots, not car sales. The Robotaxi service remains in early development and Optimus is not close to high-volume production. Investors appear to be pricing the core business for a slowdown while assigning little value to the future Musk keeps promising.
The control arithmetic
SpaceX carries a market capitalization near $2 trillion against Tesla's roughly $1.5 trillion, making SpaceX the natural acquirer in a stock swap. Musk holds 10-to-1 supervoting shares at SpaceX, giving him nearly 80% voting control. At Tesla he owns 19.8% beneficially and, as he noted on the call, any merger would require a majority of all outstanding shares to approve, not just a majority of votes cast. He also identified himself as a conflicted party who cannot sit in on the negotiations between the two special committees.
Governance as the real thesis
William Blair analysts argued Thursday that the merger logic is about control, not operational synergy. "We fully respect the overlap and collaboration potential, but view this is a truly unique case where Musk runs both companies almost as if they are one entity already," they wrote. "We are hard-pressed to find a material opportunity that could only be achieved by an official combination." Columbia law professor Eric Talley offered a counterpoint: a combination could settle shareholder litigation over divided loyalties and clarify which entity houses converging AI and robotics initiatives.
What comes next
The special committees will negotiate terms, but regulatory review looms large. A deal that consolidates Musk's voting power across a $3.5 trillion entity will attract scrutiny from antitrust and securities regulators. Tesla's proxy statement already flags the supermajority voting threshold as a high hurdle. Until the committees produce a structure, the market is left pricing two separate companies, one struggling with auto demand, the other trading below its IPO price, while the controlling shareholder decides whether they are better together.
