SpaceX has been sitting on a mountain of Bitcoin, and nobody knew how big it actually was.
An S-1 registration statement filed on May 20 reveals that the aerospace giant holds 18,712 BTC, purchased at a total cost of $661 million and valued at $1.29 billion as of March 31, 2026. That stash has since appreciated further, with current estimates placing its market value between $1.3 billion and $1.4 billion. The disclosure landed as SpaceX prepares for an IPO planned for early June 2026, giving public markets their first real look at the company’s digital asset strategy.
Here’s what makes this interesting: on-chain analysts had previously pegged SpaceX’s holdings at roughly 8,285 BTC. The actual number is more than 2.2 times that estimate. For an industry that prides itself on blockchain transparency, that’s a pretty significant miss.
The Bitcoin trail SpaceX left behind
SpaceX’s Bitcoin story isn’t new. The company began acquiring BTC years ago, with the bulk of its purchases occurring around 2021. At one point, its holdings peaked near 28,000 BTC, a position that would be worth well north of $2 billion at today’s prices.
