A potential merger between SpaceX and Tesla could significantly strengthen Elon Musk’s control over the combined company, potentially giving him approximately 56% of the voting power, according to estimates discussed in a recent analysis. The proposed combination could provide Musk with a faster route to majority control of Tesla while bringing two of his most prominent companies under one corporate structure.

Musk already holds substantial voting control at SpaceX, where a compensation arrangement reportedly gives him approximately 85% voting power. According to the analysis, this voting structure could become particularly significant if SpaceX and Tesla were to merge, potentially allowing Musk to secure majority control of the combined business.

The discussion highlights two major compensation packages awarded to Musk over the past year. One is Tesla's ambitious compensation plan, reportedly valued at around $1 trillion and linked to a series of increasingly challenging company valuation and operational milestones.

Among Tesla's targets are putting one million robotaxis on the road and producing one million humanoid robots. Musk's compensation is tied to achieving these objectives alongside significant increases in the company's market capitalization. However, his voting control over Tesla would increase as he meets the specified milestones.

The second compensation arrangement is connected to SpaceX and was established ahead of its anticipated public listing. It includes particularly ambitious objectives, such as establishing a one-million-person colony on Mars and developing space-based data centers capable of delivering 100 terawatts of computing power.

Unlike Tesla's arrangement, the SpaceX compensation structure reportedly granted Musk the voting rights associated with additional shares immediately, even though the financial rewards remain conditional on achieving specific goals. This arrangement helped increase his voting control of SpaceX to approximately 85%.

The difference between the two compensation packages is central to understanding why a potential merger could be so important for Musk. At Tesla, even completing all the milestones in his compensation plan would reportedly give him only around 29% voting control, according to figures discussed in the analysis.

A merger could change that calculation considerably. Estimates suggest that if the two companies were combined at approximately their current valuations, Musk could hold around 56% of the voting power in the resulting company. This would potentially give him majority control without having to rely entirely on completing Tesla's long-term compensation milestones.

Another important factor involves Tesla's market capitalization and the conditions attached to Musk's compensation agreement. The analysis points to a market capitalization target beginning at approximately $2 trillion, compared with Tesla's valuation of around $1.56 trillion at the time of the discussion.

Under the compensation arrangement, a change of control could trigger a provision allowing Musk to receive a payout if the required market capitalization threshold is achieved. This means that if a merger increases Tesla's value sufficiently to reach the $2 trillion target, Musk could potentially qualify for compensation without separately completing an operational milestone.

Ultimately, a SpaceX-Tesla merger could represent more than a combination of two major businesses. It could also reshape the balance of corporate voting power and give Musk greater authority over the direction of the combined company.

While the possibility of a merger raises significant questions about corporate governance, shareholder interests and the future of both businesses, the analysis suggests that the ownership and voting structures already in place at SpaceX could give Musk a substantial advantage. However, the proposed merger and its potential financial consequences remain subject to the actual transaction structure and applicable shareholder and regulatory approvals.
