SpaceX disclosed it holds 18,712 Bitcoin valued at roughly $1.45 billion as of March 31, according to its S-1 filing with the SEC ahead of its highly anticipated initial public offering. The number is more than double what tracking firms had estimated — BitcoinTreasuries.NET and Arkham had pegged the holdings at around 8,285 BTC. The revelation positions SpaceX as a major corporate whale, holding the seventh-largest Bitcoin treasury among publicly listed companies.
The numbers behind the disclosure
The filing shows SpaceX bought its Bitcoin at an average price of $35,320 each, meaning it's sitting on a healthy unrealized gain given current prices. The disclosed stash dwarfs Tesla's 11,509 Bitcoin, making SpaceX the biggest corporate holder of Bitcoin among companies with a space or automotive focus. Before this filing, the exact size of SpaceX's Bitcoin position was a guessing game.
SpaceX's Bitcoin history
SpaceX started accumulating Bitcoin in early 2021, around the same time Tesla made its own splash into digital assets. The company stayed quiet about the size of its holdings for years, while analysts and on-chain sleuths tried to piece together the wallet data. The S-1 filing finally provides official confirmation — and the number is a lot bigger than anyone expected.
What the IPO means for investors
SpaceX is aiming to raise roughly $75 billion in its IPO, targeting a valuation between $1.75 trillion and $2 trillion. The company describes its addressable market as a $28.5 trillion opportunity spanning AI, space exploration, and global connectivity. For investors buying into the IPO, they'll get indirect exposure to one of the largest corporate Bitcoin positions among public companies — a unique perk that few other tech listings offer.
Where it ranks
With 18,712 Bitcoin, SpaceX now sits seventh on the list of publicly traded companies by Bitcoin holdings, behind names like MicroStrategy and Block but well ahead of Tesla. The disclosure also settles a long-running dispute among crypto trackers over the true size of SpaceX's stack. The IPO prospectus provides the first hard data point — and it changes the narrative around corporate Bitcoin exposure in the public markets.
SpaceX's offering is expected to price later this year, with the stock trading under a ticker yet to be announced. Whether the Bitcoin disclosure boosts demand or raises regulatory eyebrows remains an open question.
