Elon Musk’s proposed merger of Tesla and SpaceX, which would create a combined entity worth roughly $3.5 trillion, has sent both companies’ valuations higher on the news, but the path to actually closing the deal runs through a far tougher obstacle than Musk himself: Tesla’s shareholder base.
Special committees made up of independent directors at both companies have been formed to explore the union, with SpaceX valued at around $2 trillion and Tesla at nearly $1.5 trillion. Markets reacted immediately, with Tesla shares rising 3.4% and SpaceX adding 7.8%, a combined $155 billion in market value, the day after Musk’s comments.
Musk described the merger as “a good idea,” pointing to potential gains from pooling engineering talent, research budgets and technology across AI software, chip design and robotics, areas where both companies are investing heavily and could otherwise be duplicating spending.
The structural challenge lies in Musk's uneven control across the two companies: he holds roughly 85% of SpaceX's voting power compared with about 20% at Tesla, meaning any deal would require support not just from a majority of shares voted, but from holders of a majority of all outstanding Tesla shares, a bar Musk himself has called "quite a high hurdle."
Whether Tesla shareholders ultimately back the deal is likely to hinge heavily on valuation and premium, with one analyst noting that a zero-premium merger would likely face real resistance, while an offer in the 20% to 40% range would probably clear shareholder opposition with little difficulty.
With both special committees still in the early stages of evaluating the structure and terms, the coming months are likely to center less on whether Musk wants the merger to happen and more on whether Tesla's board can construct an offer compelling enough to win over a shareholder base that, unlike at SpaceX, he does not control outright.
