The potential merger between Tesla and SpaceX is increasingly seen not as a matter of "if" but "when." The boundaries separating Elon Musk's two core assets are rapidly dissolving. Investors purchasing shares in either company are fundamentally investing in the same underlying asset: Elon Musk himself.
This past Wednesday, Musk presided over Tesla's first-quarter earnings call. Despite a 16% year-over-year revenue increase, automotive sales received minimal attention. The company's strategic focus has decisively shifted towards energy storage, autonomous robotaxis, and the humanoid robot Optimus. More notably, Tesla disclosed a $2 billion investment in SpaceX stock during the quarter—a rare signal of cross-company capital movement. Concurrently, SpaceX is preparing for a public listing with a valuation approaching $2 trillion, following its recent merger with Musk's social media and AI venture, xAI.
The market reaction to these developments was muted, with Tesla's stock price showing little movement after hours. This suggests investors have already priced in the reality: betting on Tesla or SpaceX is essentially a bet on Musk's vision and execution.
As capital flows between the two companies intensify and joint projects materialize, the rationale for a merger becomes increasingly coherent. The primary remaining question involves managing potential conflicts of interest—a challenge given that Musk is the largest shareholder in both entities.
**Tesla: Automotive Business Becomes "Secondary"**
Tesla's corporate narrative is undergoing a fundamental transformation. During the earnings call, vehicle sales were deliberately marginalized. While the automotive division continues to underpin the company's cash flow—generating $4 billion in operating cash flow and $1.4 billion in free cash flow for the quarter—management's vision is fixed on robotics, artificial intelligence, and the bipedal Optimus robot, described as capable of handling dangerous, repetitive, or tedious tasks.
A sharp expansion in capital expenditure underscores this strategic pivot. Musk and the CFO cautioned that full-year 2025 capital expenditures could reach $25 billion, earmarked for semiconductor production and robotics factories, significantly exceeding analyst expectations of $20 billion. According to LSEG data, analysts had projected 2026 capital expenditures at just $11 billion a year ago—expectations have more than doubled within twelve months. Certain factories are already being retooled to prepare for robot mass production. The company once defined as an electric vehicle manufacturer is increasingly resembling a comprehensive technology platform centered on Musk's ambitions.
**SpaceX: Valuation and Ambition Expand in Tandem**
SpaceX's ambitions are equally grand. This week, SpaceX revealed it had offered to acquire the AI programming tool Cursor for $60 billion, with a $10 billion breakup fee should the deal fall through. In comparison, Tesla's $2 billion purchase of SpaceX stock appears notably "restrained." This scale of ambition reaffirms SpaceX's nature as a Musk-style "moonshot" project, albeit one grounded by a fully operational satellite and rocket business.
If SpaceX proceeds with its planned public listing at a near-$2 trillion valuation, Musk would simultaneously helm the quarterly earnings calls of two major public companies. At that point, discussions about a merger would be difficult to ignore—the driving force behind both securities is, after all, the same individual.
**Terafab: A "Preview" of a Potential Merger**
The boundaries between the two companies are already blurring in a concrete project. Tesla and SpaceX, in partnership with Intel, are jointly building a semiconductor plant named "Terafab" in Texas. Musk stated that this collaboration would be reviewed by the independent directors of each company to ensure fairness to all shareholders. However, this governance arrangement faces a structural challenge: the largest shareholder of both companies is Musk himself.
This represents the core conflict of interest any potential merger must address. Nevertheless, history suggests Tesla's non-Musk shareholders have granted him significant leeway. Future public shareholders of SpaceX would likely do the same, especially since Musk is expected to hold super-voting shares, inherently limiting other shareholders' institutional influence.
**The Endgame: One Musk, One Security**
The valuation logic for both Tesla and SpaceX has little to do with recent profits or cash flow. The market is pricing Musk's long-term vision and execution capability. The fundamental conclusion is that if shareholders truly seek exposure solely to Musk's ventures, then consolidating the two companies into a single security represents the logical endgame.
Currently, no official information indicates a merger plan is in advanced stages. However, each instance of cross-company capital flow, every joint project, and the continued convergence of their business narratives brings this potential outcome closer. For investors, the question may never have been "Tesla or SpaceX?" but rather—how much do you believe in Elon Musk?
