SpaceX S-1 Discloses 18,712 BTC Holding, Over Double Earlier Estimates
SpaceX disclosed 18,712 bitcoin in its S-1 registration statement ahead of a planned Nasdaq listing. The figure is more than double the 8,285 BTC estimated from wallet tracking and exceeds Tesla's reported 11,509 BTC.

What the Filing Shows
SpaceX reported holding 18,712 bitcoin in its S-1 registration statement filed with the U.S. Securities and Exchange Commission. CoinDesk, citing the same filing, put the fair value of that position at $1.29 billion at the end of the first quarter. Crypto.news cited a value of $1.4 billion for the same balance, a gap that likely reflects a different price reference date or valuation method; the filing itself is the source to check for the exact figure.
Gap Versus Earlier Estimates
Before the filing, crypto.news had reported SpaceX's holdings at an estimated 8,285 BTC, based on Arkham-linked wallet tracking. The official balance is more than 10,000 BTC above that estimate, so on-chain attribution appears to have substantially undercounted the position. The disclosure also places SpaceX ahead of Tesla, which BitcoinTreasuries lists at 11,509 BTC. Both companies are tied to Elon Musk, who has voiced support for bitcoin at several points in past market cycles.
IPO Context
The balance appears inside one of the most closely watched IPO filings of the year. Reports cited by crypto.news point to a Nasdaq listing in June, a raise of around $75 billion, and a valuation between $1.75 trillion and $2 trillion. CoinDesk framed the target valuation at more than $1.5 trillion, a difference that the sources do not reconcile. The filing places SpaceX's addressable market at about $28.5 trillion across space, connectivity and artificial intelligence, a figure the company describes as the largest actionable total addressable market in human history.
Comparison With Corporate Bitcoin Holders
SpaceX remains far smaller than Strategy, which crypto.news reported holds 843,738 BTC after adding 24,869 BTC in a single week. Among corporate treasuries, SpaceX would rank as one of the more visible holders. The filing does not state whether the company intends to buy additional bitcoin, sell part of the position, or hold it unchanged after listing.
Why It Matters
For Traders
The 18,712 BTC disclosure is a fixed balance rather than an announced purchase, so near-term price effects depend on whether the company signals any sales or buys during the IPO process.
For Investors
A large corporate bitcoin position inside a major IPO adds a new public-market channel for bitcoin exposure and is worth tracking alongside revenue and capital spending.
For Builders
The gap between wallet-tracking estimates and the official filing shows that on-chain attribution of corporate holdings can materially undercount positions, which matters for any tooling built on that data.
