SpaceX’s new filing hints at the biggest merger ever

SpaceX slipped a new sentence into its amended IPO filing on June 1, and Wall Street immediately started reading it like a treasure map. The line says the company 'may issue a significant amount of equity in connection with future transactions.' That is the kind of phrase that can sit in a filing and still make people sit up straight, because it suggests SpaceX is preparing to use its stock as acquisition currency on a very large scale.

The same amended registration statement also added another eyebrow-raising detail: SpaceX will reserve 5% of the offering's shares for 'certain employees and persons… which may include parties with whom we have business relationships and friends and families of our executive officers.' Those shares 'will not be subject to a lockup restriction.' In plain English, that means some recipients, unlike Elon Musk and top executives who cannot sell for around a year, can sell whenever they want after the IPO, which is slated for mid-June.

That matters because the deal is already enormous. SpaceX is widely reported to be issuing 555.6 million shares at $135 each, raising roughly $75 billion. Five percent of that offering translates to about $3.75 billion in stock reserved for those favored recipients at the same insider price paid by the underwriters' institutional buyers. If the stock pops on day one, the windfall gets bigger fast. At a 20% jump, the group would gain $750 million immediately. At 30%, that jumps to $1.125 billion. And since they are not locked up, they could cash out right away. For anyone watching the IPO mechanics, this is the kind of detail that turns a headline into a live trading question.

But the bigger story is what that new sentence may be signaling about what comes next. The amended S-1's reference to issuing 'a significant amount of equity' in future transactions is being treated by some Wall Street observers as too pointed to be dismissed as boilerplate. Their read is that it raises the odds SpaceX could buy Tesla, Musk's second-largest holding. That possibility has already been floating in the background, but the filing language gives it fresh fuel.

There is another reason the market is taking the sentence seriously: SpaceX had already telegraphed a major stock-based acquisition in the original filing, and it did not get much attention at the time. The company said it could purchase venture-backed AI coding assistant Cursor for $60 billion in an all-stock transaction. That deal looks highly likely, because if SpaceX walks away, it has agreed to pay a total of $10 billion in breakup and service fees. For SpaceX shareholders, Cursor would be dilutive by around 3.5%, which is the polite way of saying their slice of the company gets smaller.

That Cursor math also reveals the style of the broader strategy. SpaceX appears willing to use what may be extremely expensive shares as currency for expansion, even if the target is priced for future promise rather than present profits. The source notes that Cursor's profits are not publicly disclosed, but at $60 billion, SpaceX would be paying roughly 20 to 30 times the company's current run rate for revenues. That is not a casual tuck-in. It is a bet that future growth will justify a very rich valuation, the same kind of bet that helped fuel SpaceX's own ascent.

Now zoom out to Tesla. If SpaceX and Tesla were combined and both sides' investors received stock in proportion to current market caps, SpaceX shareholders would give up around 45% of their company to absorb the EV maker. The resulting deal would imply a price-to-earnings ratio of over 400 for Tesla, which posted just $3.9 billion in net profits over the past four quarters. That would make it, by the source's telling, the biggest merger in history. It is exactly the kind of headline-grabbing corporate fantasy that stops being fantasy only when the math and the market make room for it.

The key point for founders, operators, investors, and board members is not whether this merger happens tomorrow. It is that SpaceX is now openly framing itself as a company that may be able to finance transformative acquisitions with highly valued equity, and that changes how the market should think about its IPO. A rich stock price is not just paper wealth. It is strategic ammo. If the shares trade well, SpaceX can use them to buy growth, recruit talent, and potentially reshape its corporate perimeter in ways that most newly public companies cannot.

That makes the filing language more than a legal footnote. It is a window into intent. SpaceX is telling investors it may be ready to deploy stock aggressively, and the targets under discussion sit at the far end of the ambition spectrum: Cursor at $60 billion, Tesla in the realm of the biggest merger ever. The catch is that both bets rely heavily on future expectations, not current profitability. That is the same sort of market psychology that can produce explosive upside and very expensive mistakes. For anyone running a company with a liquid, high-flying stock, the lesson is blunt: once your equity becomes a currency, the market will start pricing not just your business, but your buying power.
