A single sentence from SpaceX's S-1 reignites speculation about a merger with Tesla

A single sentence in the amended SpaceX S-1 (June 1, 2026) has reignited the debate about the biggest imaginable merger in the Musk ecosystem: the company declares that "may issue a significant amount of equity in connection with future transactions."

What the document exactly says

The updated SEC filing adds several provisions compared to the original May 20 prospectus. Among them:

• Reservation of up to 5% of the IPO for employees, business associates, and directors' families, without a lockup period.
• The clause on issuing equity for "future transactions", which Fortune interprets as an open door to large acquisitions or corporate combinations.

Why it points to Tesla

The connections between the two companies have tightened in 2026:

• Tesla invested approximately $2 billion in xAI, converted into a stake in SpaceX (~19 million shares, ~$3.7 billion according to 409A valuation).
• Joint project Terafab (semiconductors in Texas) between SpaceX, Tesla, and Intel.
• Cross-selling: Tesla sold $143 million in vehicles to SpaceX in May; xAI purchased $269 million in Tesla Megapacks in April.
• CNBC reported in May that Musk has discussed with close associates about "folding" SpaceX into Tesla; Tesla employees discuss it internally as a plausible scenario.

Analyst stances

Dan Ives (Wedbush) estimates an 80-90% probability of an eventual combination. Gary Black warns of a possible 28% dilution for Tesla shareholders if executed. Morningstar and other valuators question the IPO valuation (~$1.77 trillion), which would complicate structuring an "equal" deal.

No merger has been announced. The clause is standard in many prospectuses, but in the Musk context, it takes on specific weight.
