SpaceX's quarterly report puts its bitcoin at 18,712 units, worth $1,573 million on Sept. 30 and held at both Dec. 31, 2025, and Sept. 30, 2026, according to the filing it made with the SEC on Thursday afternoon [1]. Tesla's own quarterly report shows 11,509 units at Sept. 30 [2]. Add them and 30,221 bitcoin sit on the balance sheets of two Elon Musk companies whose boards have each set up special committees to study how the two might come closer together.
For anyone holding either company's shares, that changes what the bitcoin line is attached to. Today it is two separate disclosures at two separate companies. If the committees ever recommend a combination, the same coins could end up reported by one company. Neither filing says that will happen.
How the holdings are reported
Both companies carry bitcoin at fair value, meaning the balance-sheet figure moves with the market price each quarter. SpaceX says its 18,712 units cost $661 million and were worth $1,573 million on Sept. 30, down from $1,637 million at the end of 2025, and that the value is measured at Level I, the tier for assets with a quoted market price [1].
Tesla reports differently, and the difference matters. Its balance sheet shows "Digital assets" of $962 million on Sept. 30, down from $1,008 million at the end of 2025 [2]. That $962 million is all of Tesla's digital assets, not bitcoin alone. The filing says only that "the majority of our digital assets were comprised of 11,509 units of Bitcoin held at an acquisition cost of $386 million" [2]. Tesla booked a $46 million unrealized loss on digital assets in the first nine months of 2026, against a $239 million gain a year earlier [2].

On the filed numbers, the two companies together paid $1,047 million for 30,221 bitcoin (Le Coin's sum of $661 million and $386 million). A combined fair value can't be stated from the filings, because Tesla does not break out its bitcoin from its other digital assets.
What the committees are doing
The wording in the two filings is not the same, and neither describes an agreement.
SpaceX says its board "has formed a special committee to evaluate a potential combination between SpaceX and Tesla, Inc.," as announced on its Oct. 20 earnings call. "No determination by our special committee has been made regarding any potential combination," the filing says, and any combination would need approval from the committee, the board and SpaceX's controlling shareholder. "There can be no assurance that any agreement will be reached or that any transaction will be consummated" [1].
Tesla's committee of disinterested directors is "to explore deepening Tesla's relationship with SpaceX, which could be through certain arrangements including without limitation a business combination." Tesla adds that "there is no assurance that any such Transaction will be consummated," and that one would need the committee's recommendation and any necessary shareholder approval [2].
So the companies are exploring. A combination is one possible outcome that SpaceX names directly and that Tesla lists among several.
Tesla shareholders already have SpaceX exposure
One more line in Tesla's filing shows the two balance sheets are already linked. Tesla holds SpaceX shares and recorded an $863 million unrealized gain on that investment in the first nine months of 2026 [2]. It says regulatory restrictions on those shares expired in the third quarter, while customary sales restrictions tied to SpaceX's initial public offering run until December 2026 [2].
A Tesla shareholder therefore has indirect exposure to SpaceX's results, its bitcoin included, through that stake, separate from any committee outcome.
The objection
The bitcoin is small next to both businesses. SpaceX's bitcoin and Tesla's digital assets are line items, not strategies, and SpaceX reports the same 18,712 units at Dec. 31, 2025, and Sept. 30, 2026, so it neither bought nor sold on net in the first nine months of 2026 [1]. For a holder of either stock, the committee process is about rockets, satellites, cars and batteries far more than about bitcoin.
In Le Coin's view, that is right about the size and misses the reporting point. Corporate bitcoin holdings are usually read one company at a time. Here, 30,221 coins sit across two filers under one founder, with a formal process now studying whether they become one reporting company. That is worth tracking as a disclosure question even for readers who never think about the coins.
What would change the picture
The tell is in the next filings. A change in either company's unit count would be the first sign that the bitcoin itself is being managed differently. A committee recommendation, or an 8-K announcing an agreement, would be the first sign that the combination moves past evaluation. Until one of those appears, the filings describe two separate holdings and two committees that have reached no decision.
