SpaceX's IPO just put 18,712 BTC on the public leaderboard

@SpaceX's debut on the Nasdaq today did more than confirm the company's status as the largest IPO in history. It also delivered a surprise: the aerospace giant is a major Bitcoin holder, and almost nobody outside the company knew the full extent of it.

A Bitcoin Stash Hiding in Plain Sight

SpaceX's S-1 filing with the Securities and Exchange Commission first disclosed the 18,712 $BTC position in May, valued at approximately $1.29 billion at the time of filing. That figure caught analysts off guard. Blockchain analytics firm Arkham Intelligence had previously tracked SpaceX's holdings as low as 6,095 BTC, and BitcoinTreasuries.net's May 2026 Corporate Adoption Report noted that its pre-IPO private estimate stood at just 8,285 BTC. The real number was more than double those estimates.

The total cost basis was reported at $661 million, an average acquisition price of roughly $35,324 per coin. SpaceX held 18,712 bitcoin as of March 31, according to company disclosures. At bitcoin's recent price of around $63,500, those holdings are worth just under $1.2 billion, putting the position up roughly 80% from its cost basis even after this year's drawdown. The Bitcoin position represents approximately 1.8% of SpaceX's total assets, classified in the S-1 as a strategic reserve.

The company began acquiring $BTC years ago, with the bulk of its purchases occurring around 2021. Then came 2022. Bitcoin cratered, and SpaceX reduced its position during the downturn, decreasing its Bitcoin holdings by about 70%, going from roughly 28,000 BTC down to the 18,712 it holds today.

Musk's Combined Bitcoin Footprint

SpaceX officially entered the public Bitcoin treasury leaderboard as the 8th largest holder with 18,712 BTC, a position that had been building for years before its historic IPO debut confirmed the full size of the stash.

Add Tesla into the picture and the combined total becomes even more significant. Tesla made no changes to its bitcoin holdings during the first quarter of 2026, continuing to hold 11,509 BTC. Together, @elonmusk's two flagship public companies would hold more than 30,000 $BTC, placing them among the largest combined corporate holders on the public leaderboard.

Under standards published by the Financial Accounting Standards Board (FASB), SpaceX will be required to disclose the fair value of its digital currency holdings in its quarterly and annual reports, and changes in the market price of Bitcoin will be recorded directly in the company's net income. This means SpaceX's stock price may experience volatility tied to the crypto market. For investors in SPCX, that is a new dynamic worth watching closely.
