Tesla just put a SpaceX merger committee in an SEC filing. Its $2 billion SpaceX stake is already up $863 million
Tesla's board has formed a special committee of “disinterested” directors to explore "deepening Tesla's relationship with SpaceX," and Tesla now says in a legal filing that this could include "a business combination." The same filing shows Tesla already owns a slice of SpaceX: $2.0 billion invested in March, worth $2.87 billion by the end of September. That gain is about 28% of Tesla's pre-tax profit so far this year.

What Tesla filed
Tesla's quarterly report for July to September, its Form 10-Q, reached the SEC's EDGAR system at (shown in your time zone), a few hours after the Q3 earnings call. Under Part II, Item 5, it says:
"The Tesla board of directors has formed a special committee (the 'Special Committee') comprising disinterested directors to explore deepening Tesla's relationship with SpaceX, which could be through certain arrangements including without limitation a business combination."
The next sentence is the caveat: "While there could be merits to a Transaction, there is no assurance that any such Transaction will be consummated." Any deal would need "the affirmative recommendation of the Special Committee and, if agreed upon, any necessary shareholder approval."
Musk had already said on SpaceX's own earnings call on October 20 that both companies had set up special committees, that he is "a conflicted party," and that no terms have been agreed (my SpaceX Q3 write-up has his quotes). What's new is that Tesla has now said it in an SEC filing. Companies can be sued over false statements in a 10-Q, so this isn't a passing comment on a call.
Tesla has officially confirmed today that the Tesla board of directors has “formed a special committee to explore deepening Tesla’s relationship with @SpaceX, which could be through certain arrangements including without limitation a business combination.”

This is via Tesla’s 10-Q.
Post: @SawyerMerritt, (shown in your time zone).
Done, and not done
- Done: Tesla's board has formed the committee, made up of directors with no conflict (10-Q, Part II, Item 5).
- Done: Tesla invested $2.00 billion in SpaceX common stock in March 2026, for less than 1% of the company. The stake started out as preferred shares in xAI (10-Q, Note 13).
- Not done: any merger, any terms, any price or exchange ratio. The filing names no committee members and no advisers.
- Not done: the committee's recommendation or a shareholder vote. Both are required before anything happens.
- Not even promised: a merger in particular. The filing says "deepening Tesla's relationship," which could mean commercial deals short of a full combination.
Tesla is already a SpaceX shareholder, and it's winning
The part of the 10-Q most people skipped is the money. Tesla paid $2,002 million for its SpaceX shares (cash flow statement). On September 30 they were worth $2,865 million (Note 2). That's an $863 million paper gain, or about 43%, in roughly six months.
It wasn't a straight line up. Tesla booked a $142 million loss on the stake in the July to September quarter alone. That means the shares were worth about $3.0 billion at the end of June and slipped back in Q3 (my calculation from the filing's figures). The filing also says the shares moved to "Level 1" pricing in Q3, meaning they're now valued off a public market price, and that they stay under IPO sale restrictions "that expire in December 2026."
Here's the comparison that stood out to me. Tesla's pre-tax income for the first nine months of 2026 was $3,033 million. The $863 million SpaceX gain is about 28% of that. In Q3 the effect ran the other way: pre-tax income was $956 million, and without the $142 million SpaceX loss it would have been about $1,098 million, roughly 15% higher (my calculations from the 10-Q income statement). Whatever the committee decides, SpaceX is already moving Tesla's profit line.
SpaceX is also a Megapack customer
The relationship runs both ways. Note 13 shows SpaceX buying Tesla Megapack batteries "in the ordinary course of business":
- Q3 2026: $221 million of revenue from SpaceX, against $171 million of cost. That's about $50 million of gross profit, a margin of roughly 23%.
- First nine months: $626 million of revenue and $478 million of cost, or about $148 million of gross profit, a margin of about 24%.
- Still to come: SpaceX owed Tesla $729 million on September 30, and $588 million of that was for Megapacks not yet delivered. Tesla also held $648 million of deferred revenue on these contracts.
So there's already a stake, a supplier contract and, now, a committee. A "deeper relationship" doesn't start from zero.
My read
This filing doesn't make a merger more likely than it was on Tuesday's call. It makes it official. Tesla's board has a formal process, run by directors without a conflict, and it has warned shareholders in writing that nothing is guaranteed. The bull case is that Tesla already profits from SpaceX twice, as a shareholder and as a supplier. The open questions are the ones the filing doesn't answer: who sits on the committee, which bankers advise it, and what any deal would be worth to Tesla shareholders. Musk himself has called shareholder approval "quite a high hurdle." Nothing here is financial advice. The number to remember: a $2 billion bet Tesla made in March was worth $2.87 billion by the end of September, before any deal terms have been made public.
